Does anyone there know lots about setting up a dial in server using linux (specifically Red Hat 7.2)? I have a problem that I just can't pin down. We had a server running RedHat 6.2 which is our dial-in RAS server. It worked. No problems. Last week someone upgraded it to RedHat 7.2 and applied all the updates. He did not change the dial up configuration files in any way. If you dial in now, the modem connects, hand-shaking and authentication take place, and the appropriate DHCP information is passed to the client. It connects as normal, in fact, except that, after about 20 seconds from completing the connection, pings start to fail intermittently and then stop completely. Everyone (both server and client) thinks they are connected and are showing the correct information for IP, DNS and so on, but the traffic simply stops. The messages file simply shows the normal connection information, as though the link is working fine. Has anyone seen this before? Can you think of a fix? Naturally, it's urgent (like all computer problems... ;) Oh, I tried adding 'debug' to the line in login.config, and also changing the debug level in mgetty.config. but I'm not getting any increase in error information in /var/log/messages. Here are the configuration details (with the IPs and Names changed to protect the innocent... ).
