Default unknown host pspnet.no-ip.info

Hi,

I seem to be unable to start the llrnet client on my RHEL5 box. I'm sure I'm doing something wrong, but here's the error message I get:

nice -20 ./llrnet
Running 'init.lua' ...
Loading library 'basic' ...
Loading library 'client' ...
Loading library 'client_server' ...
LLR network client 0.9b7 started
Based on LLR version 3.5.0
Loading library 'win32' ...
unknown host pspnet.no-ip.info
LLRMain started
server dialog thread started ...
unknown host pspnet.no-ip.info

Thanks for your time,

Some linux Distributions have problems with the DNS resolution when it is calledfrom the llrnet client.

Try:

server=62.75.240.56

I hope it is the correct IP. From my office ping to the outside world is blocked so I can not check it from here.
So maybe best way is first ping www.psp-project.de and then use the ip shown.

This is due the statically linked executable and different glibc on your host than the one on the host that llrnet was compiled.

The function "gethostbyname" used when you try to resolve that DNS address to an IP address will not return anything at all if your glibc is slightly different than the one used for linking.

Actually, you will get a warning while compiling:
Code:
warning: Using 'gethostbyname' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
There is no simple way of solving this, other than using an IP address. If you want, you could try to compile the source yourself, or you could try to locate what version of glibc was used and install that on your RHEL box (last one sound horribly painfull and potentially dangerous).

Thanks for your kind input. I don't mind hardcoding the IP into the config, so I'm all set.

@puh_32: Sorry for forgeting the """

@runesk: Thanks for giving the background information why this happens. Till now i did only know that there is a problem but had no clue about the reason.
