DNS problematic

Ciao,

i have a gemstone 3.4.2 run on Ubuntu system.

Sometime the internet connection is down or the

provider's DNS server don't answer.

In these cases when i do, from tode shell, the command:

GsSocket getHostAddressByName: 'www.gemtalksystems.com'.

the tode shell is blocked for 100 seconds.

After the tode report:

ArgumentError: getaddrinfo failed, EAI error -3, Errore temporaneo nella risoluzione del nome, 

--------------------

1. ArgumentError(AbstractException)>>_signalFromPrimitive: @6 line 15

2. GsSocket class>>_twoArgClassPrim:with:with: @1 line 1

3. GsSocket class>>getHostAddressesByName: @3 line 13

4. GsSocket class>>getHostAddressByName: @3 line 16

16. TDWorkspaceClientElementBuilder(ExecBlock)>>value:value:value:value:value: @2 line 11

17. GsNMethod class>>_gsReturnToC @1 line

I think same problem from relative gem execution.

How i can manage this problematic ?

I can define a relative timeout ?

Other question:

when the dns works the system replies a string like:

'::ffff:138.197.233.120'

how i can, which is the best way, to translate it to Ipv4 ?

Thanks,

Dario

Dario,

At the moment there is no way to set a timeout on the `getHostAddressByName:` call, but we may add that feature in a future release so keeps your eyes peeled. It might be possible to change the time out by modifying /etc/resolv.conf.

If the result begins with '::ffff:' then you should be able to just remove that prefix from the result and have an IPv4 address.
