Hi, I've installed redhat 7.1 few weeks back on a PC running Pentium 200 MHz, 128 MB. The network is configured with DHCP server on a secure intra-network within the company as a development box. I am having telnet session timing out problem when I telnet into the box as root. After about 10 minutes, the telnet session hangs or not responds any more. If I go to the console window, and execute a ping command, then the telnet session resumes. I think I don't have this problem when I telneting out from the box to remote hosts. I tried make /etc/pam.d/other file to be generic as possible but the problem (could be called a feature with the PAM default configuration) persists. Does anyone run into this problem in redhat 7.1 ? Anyone knows how I can disable (or work-around) the 10-min timeout on telnet session ? It is not clear to me whether this problem is with PAM or XINETD. Thanks, Moo /etc/xinetd.d/telnet: # default: on # description: The telnet server serves telnet sessions; it uses \ # unencrypted username/password pairs for authentication. service telnet { flags = REUSE socket_type = stream wait = no user = root server = /usr/sbin/in.telnetd log_on_failure += USERID disable = no } boot message : eepro100.c:v1.09j-t 9/29/99 Donald Becker http://cesdis.gsfc.nasa.gov/linux/drivers/eepro100.html eepro100.c: $Revision: 1.36 $ 2000/11/17 Modified by Andrey V.
