Hi,

Thanks for your answer sysgate. Youīve got it rigth, I canīt establish any data transfer session even though network connection seems to be OK. Here some answers to your questions.

1) Iīve tried to SSH, telnet and ftp several public sites. All these programs just hault, they seem be waiting some response that never comes. The process go to 'idle' state very soon after execution, network monitor shows some send/receive activity.

2) Network settings come from DHCP. IP address looks to be OK. I tried to disable ipv6 also but it didnīt help.

3) No proxies involved, direct connection to internet using Zyxel ADSL/WLAN box.

4) I have root access.

5) I have MS Vista installed also in the same machine. It setups the network automatically and connecto to internet without any problems.

6) I tried RHEL 5 server version too, no success

7) After RHEL I decided to try Fedora 10. Setup was done the same way and everything works fine eith it. The settings seem to be pretty much similar, the only differences Iīve found so far is that in Fedora the HOST name in prompt is 'localhost' as in RHEL it's 'DHCPPC'. Fedora also has xinetd.d service available that were missing form RHEL installation. That might be the reason?

I think I go with Fedora for a while and take copy of itīs config files for comparison before trying RHEL again.

RXTELNET(1)						    BSD General Commands Manual 					       RXTELNET(1)

NAME
rxtelnet -- start a telnet and forward X-connections. SYNOPSIS
rxtelnet [-l username] [-k] [-t telnet_args] [-x xterm_args] [-K kx_args] [-w term_emulator] [-b telnet_program] [-n] [-v] host [port] DESCRIPTION
The rxtelnet program starts an xterm window with a telnet to host host. From this window you will also be able to run X clients that will be able to connect securely to your X server. If port is given, that port will be used instead of the default. If setting up the X forwarding failes, rxtelnet will still telnet in to the remote host, but without X forwarding. The supported options are: -l Log in on the remote host as user username. -k Disables keep-alives. -t Send telnet_args as arguments to telnet. -x Send xterm_args as arguments to xterm. -X Send kx_args as arguments to kx. -w Use term_emulator instead of xterm. -b Use telnet_program instead of telnet. -n Do not start any terminal emulator. -v Be verbose. EXAMPLE
To login from host foo (where your display is) to host bar, you might do the following. 1. On foo: rxtelnet bar 2. You will get a new window with a telnet to bar. In this window you will be able to start X clients. SEE ALSO
