[Glass] Ubuntu 14.04 ethernet static ip and GemTools login

Dale,

tODE client works into remote without problem.

GemTools not. 

it's strange !?

It's a  GemTools-1.0-beta.8.7-3101x.sh definition problem ?

 

Dario

Dario,

I don't have a clue at this point, since that was the formula that worked for me ...

Below is  the script that I used to install all of the prerequisites using the `-G -X -o ubuntu14.04` options...

Okay in addition to the published 14.04 prereqs[1] (including X11 client prereqs[2]), the following two packages need to be loaded for GemTools to work on Ubuntu14.04:

  sudo apt-get install sane:i386
  sudo apt-get install libsm6:i386

Dario,

I think I have stumbled across the magic for getting GemTools to run on 14.04. Try this:

  sudo apt-get install libx11-6:i386 libsm6:i386

I had done some other installs along the way, but with no success ... Since I've pretty much trashed my ubuntu vms during this excercise, I will have to start with fresh ubuntu installs to verify exactly what is needed and that will be a little while ...

When I'm done I will verify and include the GemTools information in the soon to be released gsDevKitHome 1.0.0 documentation:)

Not sure right now ... Pharo1.1 must have a different set of prerequisites ... it will take a bit of time for me to figure that out, I suppose you could try running GemTools over the lan using the ssh port forwarding until I figure out the missing prerequisites ...

No after reboot the Ubuntu system server,  the GemTools  on macBook don't work,

 because when i open the ssh session with :

meetingto:~ dtr$ ssh  scandella -l scandella -L 57858:localhost:57858 -L 57860:localhost:5786

Dale,

Dario,

Good questions.

As part of my work for the soon to be released gsDevKitHome 1.0.0, I have taken a pretty close look at the prerequisites[2] and I've got a detailed list of the prerequisites for Ubuntu14.04[2]. I think I've added a couple of prereqs since you've done an install ... mainly in the areas of support for ptrace (C stack straces) and freetype fonts for pharo.  Check you list against the required prereqs[5].

I don't verify the prerequisite for now.

It looks like you have the X11 Client already installed on the server, so you will need to install GemTools on the server. You should just be able to scp the GemTools zip file over to the server and go ...

I open ssh session with:

ssh -X scandella -l scandella -L 57858:localhost:57858 -L 57860:localhost:57860

And submit:

export GS_HOME=/opt/oodb/gsDevKitHome

export PATH=$GS_HOME/bin:$PATH

$GS_HOME/bin/todeClient

It work fine and i can submit tODE command on: gestionale    environment

After i download  and unzip:  http://seaside.gemtalksystems.com/squeak/GemTools-1.0-beta.8.7-310x.zip  

When i  submit:

[hidden email] ./GemTools-1.0-beta.8.7-3101x.sh

the system answer:

could not find module vm-display-X11 Annullato (core dump creato)

Any idea about it?

Another questions about macBook GemTools problem.

after reboot the server Ubuntu system now when i open a ssh on my macBook with:

meetingto:~ dtr$ ssh  scandella -l scandella -L 57858:localhost:57858 -L 57860:localhost:5786

the system answer:

bind: Address already in use

Could not request local forwarding.

Welcome to Ubuntu 14.04.2 LTS (GNU/Linux 3.13.0-24-generic x86_64)

A this point when i open the GemTools on my macBook and open the session the system answer:

Error: Unable to create a GemStone session.

NetLDI service '57858' not found on node 'localhost' port 57858 :

 For further information about login failures, check the gem log file

I don't understund because 57858 i already in use after reboot the system.

Before use the ssh -X ..................  all worked well,  at the login the 57858 is free  and GemTools session work fine.

Any considerations?

Thanks,

Dario

For the best performance using GemTools, I think that X11 forwarding[3] (instructions included) is probably the best option. In my limited experience using X11 forwarding (with compression) with tODE, the update delays are not nearly as annoying as the pretty long round trip induced delays seen when using GemTools over the WAN.

On the other hand, I think that SSH port forwarding[4] is the best option for tODE. tODE does a pretty good job of limiting the number of round trips so having snappier window updates is appreciated.

Does that clarify things for you?

Dale, Mariano,

for now my server tODE environment is installed into my office and i don't have performance problem with GemTools.

But the next week the server will installed on remote office of my client and i'm interested to work on it from my home office on WAN.

But i don't have clear that i need to install on the server.

The server is based on Ubuntu 14.04 server  and for now i installed:

sudo apt-get -y install git

sudo apt-get -y install unzip

sudo apt-get -y install curl

sudo apt-get -y install libpam0g:i386

sudo apt-get -y install libxcb-dri2-0:i386

What other i need to load ? 

What i need to load for GemTools on the server ( and relative prerequisite ) ?

After installed all, how i can test the GemTools load on the server with X11 forwarding ?

Into another e-mail Dale write: 

Things are a bit snappier if I use port forwarding, but the advantage of XLL forwarding is that you don't have to install GemTools on the remote system...

But relative performance are good?

What is the best solutions, i'm confusing?

Thanks for any help, considerations.

Dario

Mariano,

You have a point that ssh tunneling for X may be a better option ...

Dario, When we get the port forwarding option working, you can give X11 forwarding a go.

You'd need to install the X client on your server and I have another little writeup (that's part of the soon to be release gsDevKitHome 1.0.0) that details the X packages that need to be installed for X11 client [1], since you don't need the full blown X server for X11 forwarding.

Dario, 

I did not read the full email.... but If you allow me a quick recommendation (maybe offtopic here), I would not use remote GemTools. It is really too slow and becomes unusable. It is far easier and faster to use SSH with X forward and run GemTools locally in your server. So in GemTools you simply put localhost etc... and then do ssh -X etc..

And you can even improve performance of SSH with X by doing:

alias ssh-x='ssh -c arcfour,blowfish-cbc -XC'

then ssh-x myserver...

Best,

Dario,

I'll have to wait for Martin to chime in with what he thinks may be going on now ...

but, I'm inclined to take a different tack to address your GemTools remote login problem.

You have ssh installed and you can log into the remote machine using ssh, so you should be able to setup ssh port forwarding for GemTools.

I've done a writeup on this as part of the soon to be released gsDevKitHome 1.0.0[1].

In a nutshell you do the following (after setting up the static ip address):

ssh scandella -l scandella -L 57858:localhost:57858  -L 57860:localhost:57860
# cd to your gestionale directory                                        
. defStone.env                                                                    
$GEMSTONE/bin/startnetldi -a scandella -g -p 57860:57860 -P 57858 gestionale

OK i do this test, i report what i do:

before we get to the point where we are trying to debug the startNetldi script, let's verify that you can start a netldi that works with your remote GemTools. So:

  1. login in as the user that is running your stone processes

I login as  scandella

  2. cd $GS_HOME/gemstone/stones/<stone-name>

i go to my  gestionale  stone   directory

  3. execute the following bash script:
      .  defStone.env

i do the command:     . defStone.env ( with a blank after the. )

  4. then manually start the netldi:
      $GEMSTONE/bin/startnetldi -g -a $USER -A192.168.1.10 -l \
                                                  $GEMSTONE_LOGDIR/${GEMSTONE_NAME}_ldi.log \
                                                   ${GEMSTONE_NAME}_ldi

i do the command :

    $GEMSTONE/bin/startnetldi -g -a scandella -A192.168.1.10 -l $GEMSTONE_LOGDIR/gestionale_ldi.log \gestionale_ldi

It don't work, when i do the GemTools login the system go into loop

When we get GemTools working with a manually started netldi, then you can try changing the startNetldi script.

OK, thanks. From your previous message I wasn't sure whether you were
still seeing the problem.

Considerations?

The netldi is only listening on the IPv6 localhost address. If you want
to use GemTools from another machine, it must also listen on the
192.168.1.10 address. I'm not sure why it isn't already listening on
that address, but you should be able to fix it by adding -A192.168.1.10
to your startnetldi command line (see the man page for startnetldi).

Once you've started netldi with that option, netstat -ltpn should show
netldi listening on that address.

First: my environment is based on tODE and i think to change the file  startNetldi

adding some parameter to the last line.

#! /bin/bash

$GS_HOME/bin/tode startnetldi $stoneName -A192.168.1.10

But with this information when i do the command :   startNetlidi gestionale   i don't solve the problem.

The  netstat -ltpn    don't report  netldi listening on that address.

Second: in addition  the service are  started with Daemontools Gemstone service and  i don't know where i need add the -A parameter.

Anyone know informations about it ?

GemTools not. 

it's strange !?

It's a  GemTools-1.0-beta.8.7-3101x.sh definition problem ?

 

Dario

Dario,

I don't have a clue at this point, since that was the formula that worked for me ...

Below is  the script that I used to install all of the prerequisites using the `-G -X -o ubuntu14.04` options...

Okay in addition to the published 14.04 prereqs[1] (including X11 client prereqs[2]), the following two packages need to be loaded for GemTools to work on Ubuntu14.04:

  sudo apt-get install sane:i386
  sudo apt-get install libsm6:i386

I think I have stumbled across the magic for getting GemTools to run on 14.04. Try this:

  sudo apt-get install libx11-6:i386 libsm6:i386

I had done some other installs along the way, but with no success ... Since I've pretty much trashed my ubuntu vms during this excercise, I will have to start with fresh ubuntu installs to verify exactly what is needed and that will be a little while ...

When I'm done I will verify and include the GemTools information in the soon to be released gsDevKitHome 1.0.0 documentation:)

Not sure right now ... Pharo1.1 must have a different set of prerequisites ... it will take a bit of time for me to figure that out, I suppose you could try running GemTools over the lan using the ssh port forwarding until I figure out the missing prerequisites ...

No after reboot the Ubuntu system server,  the GemTools  on macBook don't work,

 because when i open the ssh session with :

meetingto:~ dtr$ ssh  scandella -l scandella -L 57858:localhost:57858 -L 57860:localhost:5786

Dale,

Dario,

Good questions.

As part of my work for the soon to be released gsDevKitHome 1.0.0, I have taken a pretty close look at the prerequisites[2] and I've got a detailed list of the prerequisites for Ubuntu14.04[2]. I think I've added a couple of prereqs since you've done an install ... mainly in the areas of support for ptrace (C stack straces) and freetype fonts for pharo.  Check you list against the required prereqs[5].

I don't verify the prerequisite for now.

It looks like you have the X11 Client already installed on the server, so you will need to install GemTools on the server. You should just be able to scp the GemTools zip file over to the server and go ...

I open ssh session with:

ssh -X scandella -l scandella -L 57858:localhost:57858 -L 57860:localhost:57860

And submit:

export GS_HOME=/opt/oodb/gsDevKitHome

export PATH=$GS_HOME/bin:$PATH

$GS_HOME/bin/todeClient

It work fine and i can submit tODE command on: gestionale    environment

After i download  and unzip:  http://seaside.gemtalksystems.com/squeak/GemTools-1.0-beta.8.7-310x.zip  

When i  submit:

[hidden email] ./GemTools-1.0-beta.8.7-3101x.sh

Any idea about it?

Another questions about macBook GemTools problem.

after reboot the server Ubuntu system now when i open a ssh on my macBook with:

Could not request local forwarding.

Welcome to Ubuntu 14.04.2 LTS (GNU/Linux 3.13.0-24-generic x86_64)

A this point when i open the GemTools on my macBook and open the session the system answer:

Error: Unable to create a GemStone session.

NetLDI service '57858' not found on node 'localhost' port 57858 :

 For further information about login failures, check the gem log file

I don't understund because 57858 i already in use after reboot the system.

Before use the ssh -X ..................  all worked well,  at the login the 57858 is free  and GemTools session work fine.

Any considerations?

Thanks,

Dario

For the best performance using GemTools, I think that X11 forwarding[3] (instructions included) is probably the best option. In my limited experience using X11 forwarding (with compression) with tODE, the update delays are not nearly as annoying as the pretty long round trip induced delays seen when using GemTools over the WAN.

On the other hand, I think that SSH port forwarding[4] is the best option for tODE. tODE does a pretty good job of limiting the number of round trips so having snappier window updates is appreciated.

Does that clarify things for you?

Dale, Mariano,

for now my server tODE environment is installed into my office and i don't have performance problem with GemTools.

But the next week the server will installed on remote office of my client and i'm interested to work on it from my home office on WAN.

But i don't have clear that i need to install on the server.

The server is based on Ubuntu 14.04 server  and for now i installed:

sudo apt-get -y install git

What other i need to load ? 

What i need to load for GemTools on the server ( and relative prerequisite ) ?

After installed all, how i can test the GemTools load on the server with X11 forwarding ?

Into another e-mail Dale write: 

Things are a bit snappier if I use port forwarding, but the advantage of XLL forwarding is that you don't have to install GemTools on the remote system...

But relative performance are good?

What is the best solutions, i'm confusing?

Thanks for any help, considerations.

Dario

Mariano,

You have a point that ssh tunneling for X may be a better option ...

Dario, When we get the port forwarding option working, you can give X11 forwarding a go.

You'd need to install the X client on your server and I have another little writeup (that's part of the soon to be release gsDevKitHome 1.0.0) that details the X packages that need to be installed for X11 client [1], since you don't need the full blown X server for X11 forwarding.

Dario, 

I did not read the full email.... but If you allow me a quick recommendation (maybe offtopic here), I would not use remote GemTools. It is really too slow and becomes unusable. It is far easier and faster to use SSH with X forward and run GemTools locally in your server. So in GemTools you simply put localhost etc... and then do ssh -X etc..

And you can even improve performance of SSH with X by doing:

alias ssh-x='ssh -c arcfour,blowfish-cbc -XC'

then ssh-x myserver...

Best,

Dario,

I'll have to wait for Martin to chime in with what he thinks may be going on now ...

but, I'm inclined to take a different tack to address your GemTools remote login problem.

You have ssh installed and you can log into the remote machine using ssh, so you should be able to setup ssh port forwarding for GemTools.

I've done a writeup on this as part of the soon to be released gsDevKitHome 1.0.0[1].

In a nutshell you do the following (after setting up the static ip address):

ssh scandella -l scandella -L 57858:localhost:57858  -L 57860:localhost:57860
# cd to your gestionale directory

OK i do this test, i report what i do:

before we get to the point where we are trying to debug the startNetldi script, let's verify that you can start a netldi that works with your remote GemTools. So:

  1. login in as the user that is running your stone processes

I login as  scandella

  2. cd $GS_HOME/gemstone/stones/<stone-name>

i go to my  gestionale  stone   directory

  3. execute the following bash script:

i do the command:     . defStone.env ( with a blank after the. )

  4. then manually start the netldi:

                                                  $GEMSTONE_LOGDIR/${GEMSTONE_NAME}_ldi.log \

It don't work, when i do the GemTools login the system go into loop

When we get GemTools working with a manually started netldi, then you can try changing the startNetldi script.

OK, thanks. From your previous message I wasn't sure whether you were
still seeing the problem.

Considerations?

The netldi is only listening on the IPv6 localhost address. If you want
to use GemTools from another machine, it must also listen on the
192.168.1.10 address. I'm not sure why it isn't already listening on
that address, but you should be able to fix it by adding -A192.168.1.10
to your startnetldi command line (see the man page for startnetldi).

Once you've started netldi with that option, netstat -ltpn should show
netldi listening on that address.

First: my environment is based on tODE and i think to change the file  startNetldi

adding some parameter to the last line.

#! /bin/bash

But with this information when i do the command :   startNetlidi gestionale   i don't solve the problem.

The  netstat -ltpn    don't report  netldi listening on that address.

Second: in addition  the service are  started with Daemontools Gemstone service and  i don't know where i need add the -A parameter.

Anyone know informations about it ?

So Dario,

Just to check ...

tODE works when run on the server (using X11 forwarding) or on your local macbook (using port forwarding).

GemTools works on your local macbook (using port forwarding) and not on the server (with X11 forwarding)...

The latest stable vm for Pharo-3.0 does not work with the old Pharo1.1 images, so we will need to figure out the magic that it takes to get GemTools working on your server .... I have it working on my server, but I will try again to verify that I didn't sneak in a package upgrade that I forgot to include ...

Okay in addition to the published 14.04 prereqs[1] (including X11 client prereqs[2]), the following two packages need to be loaded for GemTools to work on Ubuntu14.04:

  sudo apt-get install sane:i386
  sudo apt-get install libsm6:i386

I think I have stumbled across the magic for getting GemTools to run on 14.04. Try this:

  sudo apt-get install libx11-6:i386 libsm6:i386

I had done some other installs along the way, but with no success ... Since I've pretty much trashed my ubuntu vms during this excercise, I will have to start with fresh ubuntu installs to verify exactly what is needed and that will be a little while ...

When I'm done I will verify and include the GemTools information in the soon to be released gsDevKitHome 1.0.0 documentation:)

Not sure right now ... Pharo1.1 must have a different set of prerequisites ... it will take a bit of time for me to figure that out, I suppose you could try running GemTools over the lan using the ssh port forwarding until I figure out the missing prerequisites ...

No after reboot the Ubuntu system server,  the GemTools  on macBook don't work,

Good questions.

As part of my work for the soon to be released gsDevKitHome 1.0.0, I have taken a pretty close look at the prerequisites[2] and I've got a detailed list of the prerequisites for Ubuntu14.04[2]. I think I've added a couple of prereqs since you've done an install ... mainly in the areas of support for ptrace (C stack straces) and freetype fonts for pharo.  Check you list against the required prereqs[5].

I don't verify the prerequisite for now.

It looks like you have the X11 Client already installed on the server, so you will need to install GemTools on the server. You should just be able to scp the GemTools zip file over to the server and go ...

I open ssh session with:

ssh -X scandella -l scandella -L 57858:localhost:57858 -L 57860:localhost:57860

And submit:

export GS_HOME=/opt/oodb/gsDevKitHome

export PATH=$GS_HOME/bin:$PATH

$GS_HOME/bin/todeClient

It work fine and i can submit tODE command on: gestionale    environment

After i download  and unzip:  http://seaside.gemtalksystems.com/squeak/GemTools-1.0-beta.8.7-310x.zip  

When i  submit:

[hidden email] ./GemTools-1.0-beta.8.7-3101x.sh

Welcome to Ubuntu 14.04.2 LTS (GNU/Linux 3.13.0-24-generic x86_64)

A this point when i open the GemTools on my macBook and open the session the system answer:

Error: Unable to create a GemStone session.

NetLDI service '57858' not found on node 'localhost' port 57858 :

I don't understund because 57858 i already in use after reboot the system.

Before use the ssh -X ..................  all worked well,  at the login the 57858 is free  and GemTools session work fine.

Any considerations?

Thanks,

For the best performance using GemTools, I think that X11 forwarding[3] (instructions included) is probably the best option. In my limited experience using X11 forwarding (with compression) with tODE, the update delays are not nearly as annoying as the pretty long round trip induced delays seen when using GemTools over the WAN.

On the other hand, I think that SSH port forwarding[4] is the best option for tODE. tODE does a pretty good job of limiting the number of round trips so having snappier window updates is appreciated.

Does that clarify things for you?

After installed all, how i can test the GemTools load on the server with X11 forwarding ?

Into another e-mail Dale write: 

Things are a bit snappier if I use port forwarding, but the advantage of XLL forwarding is that you don't have to install GemTools on the remote system...

But relative performance are good?

What is the best solutions, i'm confusing?

Thanks for any help, considerations.

Mariano,

You have a point that ssh tunneling for X may be a better option ...

Dario, When we get the port forwarding option working, you can give X11 forwarding a go.

You'd need to install the X client on your server and I have another little writeup (that's part of the soon to be release gsDevKitHome 1.0.0) that details the X packages that need to be installed for X11 client [1], since you don't need the full blown X server for X11 forwarding.

Dario, 

I did not read the full email.... but If you allow me a quick recommendation (maybe offtopic here), I would not use remote GemTools. It is really too slow and becomes unusable. It is far easier and faster to use SSH with X forward and run GemTools locally in your server. So in GemTools you simply put localhost etc... and then do ssh -X etc..

And you can even improve performance of SSH with X by doing:

alias ssh-x='ssh -c arcfour,blowfish-cbc -XC'

then ssh-x myserver...

I'll have to wait for Martin to chime in with what he thinks may be going on now ...

You have ssh installed and you can log into the remote machine using ssh, so you should be able to setup ssh port forwarding for GemTools.

I've done a writeup on this as part of the soon to be released gsDevKitHome 1.0.0[1].

In a nutshell you do the following (after setting up the static ip address):

ssh scandella -l scandella -L 57858:localhost:57858  -L 57860:localhost:57860
# cd to your gestionale directory

When we get GemTools working with a manually started netldi, then you can try changing the startNetldi script.

OK, thanks. From your previous message I wasn't sure whether you were
still seeing the problem.

Considerations?

The netldi is only listening on the IPv6 localhost address. If you want
to use GemTools from another machine, it must also listen on the
192.168.1.10 address. I'm not sure why it isn't already listening on
that address, but you should be able to fix it by adding -A192.168.1.10
to your startnetldi command line (see the man page for startnetldi).

Once you've started netldi with that option, netstat -ltpn should show
netldi listening on that address.

First: my environment is based on tODE and i think to change the file  startNetldi

adding some parameter to the last line.

But with this information when i do the command :   startNetlidi gestionale   i don't solve the problem.

The  netstat -ltpn    don't report  netldi listening on that address.

Second: in addition  the service are  started with Daemontools Gemstone service and  i don't know where i need add the -A parameter.

Dario, it's very likely you are missing to install a lib in Linux needed by Pharo VM. An easy way to detect that is to do a ldd over the VM binary. Try to do something like this:

sudo ldd /opt/gemstoneAdditions/GemTools-1.0-beta.8.7-3101x.app/Contents/Linux686/squeak

Change that path for the accurate for your server. And check paste us the output of such a command. It may suggest a lib is missing. If true, let us know which one. 

Cheers,

Dario,

I just tried again and I started with an ico downloaded from the ubuntu site:

  ubuntu-14.04-server-amd64.iso

Created the vm using vmware player 7.x.

Installed ssh manually:
  sudo apt-get -y update
  sudo apt-get -y install openssh-client
  sudo apt-get -y install openssh-server

scp'd the osPrereqs script that I mailed you to the server and ran it with:

  ./osPrereqs -G -X -o ubuntu14.04

When it finished I logged out and back in using the `X` flag to ssh:

  ssh 192.168.100.131 -l dhenrich -X

then launched GemTools on the server

  GemTools-1.0-beta.8.7-3101x.app/GemTools-1.0-beta.8.7-3101x.sh &

and it came up fine ...


Soooo, there must be something different about the setup of your Ubuntu14.0.4 virtual machine ...

Now I never did track the exact X11:i386 library that was needed by the Pharo1.1.x vm, but the sane:i386 did the trick for me...

So Dario,

Just to check ...

tODE works when run on the server (using X11 forwarding) or on your local macbook (using port forwarding).

GemTools works on your local macbook (using port forwarding) and not on the server (with X11 forwarding)...

The latest stable vm for Pharo-3.0 does not work with the old Pharo1.1 images, so we will need to figure out the magic that it takes to get GemTools working on your server .... I have it working on my server, but I will try again to verify that I didn't sneak in a package upgrade that I forgot to include ...

Okay in addition to the published 14.04 prereqs[1] (including X11 client prereqs[2]), the following two packages need to be loaded for GemTools to work on Ubuntu14.04:

  sudo apt-get install sane:i386
  sudo apt-get install libsm6:i386

I think I have stumbled across the magic for getting GemTools to run on 14.04. Try this:

I had done some other installs along the way, but with no success ... Since I've pretty much trashed my ubuntu vms during this excercise, I will have to start with fresh ubuntu installs to verify exactly what is needed and that will be a little while ...

When I'm done I will verify and include the GemTools information in the soon to be released gsDevKitHome 1.0.0 documentation:)

Not sure right now ... Pharo1.1 must have a different set of prerequisites ... it will take a bit of time for me to figure that out, I suppose you could try running GemTools over the lan using the ssh port forwarding until I figure out the missing prerequisites ...

No after reboot the Ubuntu system server,  the GemTools  on macBook don't work,

Dale,

Good questions.

As part of my work for the soon to be released gsDevKitHome 1.0.0, I have taken a pretty close look at the prerequisites[2] and I've got a detailed list of the prerequisites for Ubuntu14.04[2]. I think I've added a couple of prereqs since you've done an install ... mainly in the areas of support for ptrace (C stack straces) and freetype fonts for pharo.  Check you list against the required prereqs[5].

I don't verify the prerequisite for now.

It looks like you have the X11 Client already installed on the server, so you will need to install GemTools on the server. You should just be able to scp the GemTools zip file over to the server and go ...

I open ssh session with:

ssh -X scandella -l scandella -L 57858:localhost:57858 -L 57860:localhost:57860

And submit:

export GS_HOME=/opt/oodb/gsDevKitHome

export PATH=$GS_HOME/bin:$PATH

$GS_HOME/bin/todeClient

It work fine and i can submit tODE command on: gestionale    environment

After i download  and unzip:  http://seaside.gemtalksystems.com/squeak/GemTools-1.0-beta.8.7-310x.zip  

When i  submit:

[hidden email] ./GemTools-1.0-beta.8.7-3101x.sh

Any considerations?

For the best performance using GemTools, I think that X11 forwarding[3] (instructions included) is probably the best option. In my limited experience using X11 forwarding (with compression) with tODE, the update delays are not nearly as annoying as the pretty long round trip induced delays seen when using GemTools over the WAN.

On the other hand, I think that SSH port forwarding[4] is the best option for tODE. tODE does a pretty good job of limiting the number of round trips so having snappier window updates is appreciated.

Does that clarify things for you?

After installed all, how i can test the GemTools load on the server with X11 forwarding ?

Into another e-mail Dale write: 

Things are a bit snappier if I use port forwarding, but the advantage of XLL forwarding is that you don't have to install GemTools on the remote system...

But relative performance are good?

What is the best solutions, i'm confusing?

Thanks for any help, considerations.

Dario

Mariano,

You have a point that ssh tunneling for X may be a better option ...

Dario, When we get the port forwarding option working, you can give X11 forwarding a go.

You'd need to install the X client on your server and I have another little writeup (that's part of the soon to be release gsDevKitHome 1.0.0) that details the X packages that need to be installed for X11 client [1], since you don't need the full blown X server for X11 forwarding.

Dario, 

I did not read the full email.... but If you allow me a quick recommendation (maybe offtopic here), I would not use remote GemTools. It is really too slow and becomes unusable. It is far easier and faster to use SSH with X forward and run GemTools locally in your server. So in GemTools you simply put localhost etc... and then do ssh -X etc..

And you can even improve performance of SSH with X by doing:

alias ssh-x='ssh -c arcfour,blowfish-cbc -XC'

then ssh-x myserver...

Best,

You have ssh installed and you can log into the remote machine using ssh, so you should be able to setup ssh port forwarding for GemTools.

I've done a writeup on this as part of the soon to be released gsDevKitHome 1.0.0[1].

In a nutshell you do the following (after setting up the static ip address):

ssh scandella -l scandella -L 57858:localhost:57858  -L 57860:localhost:57860

When we get GemTools working with a manually started netldi, then you can try changing the startNetldi script.

OK, thanks. From your previous message I wasn't sure whether you were
still seeing the problem.

Considerations?

The netldi is only listening on the IPv6 localhost address. If you want
to use GemTools from another machine, it must also listen on the
192.168.1.10 address. I'm not sure why it isn't already listening on
that address, but you should be able to fix it by adding -A192.168.1.10
to your startnetldi command line (see the man page for startnetldi).

Once you've started netldi with that option, netstat -ltpn should show
netldi listening on that address.

First: my environment is based on tODE and i think to change the file  startNetldi

adding some parameter to the last line.

stonePath=$GS_HOME/gemstone/stones/$stoneName

pushd $stonePath >& /dev/null

source $stonePath/stone.env

popd >& /dev/null

$GS_HOME/bin/tode startnetldi $stoneName -A192.168.1.10

But with this information when i do the command :   startNetlidi gestionale   i don't solve the problem.

The  netstat -ltpn    don't report  netldi listening on that address.

Second: in addition  the service are  started with Daemontools Gemstone service and  i don't know where i need add the -A parameter.

Anyone know informations about it ?

Thanks,

Dario
