Hi, We have installed Red hat 7.1 Linux one of our customer location. It used work all network service (ftp, telnet, ssh) etc. Because of power failure file system got crashed, then we did fsck manually. Now system is booting without any problem, it was able send outgoing request (telnet, ftp, ping). >From other machine only ping request work, all other network services are not working. While booting the machine about 30 sec, It allows us to login that after the it's terminating the telnet connection. I did some google search, got the following message. http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&th=5f887abf1be0e 4ca&rnum=14 We turned off the firewall, still its not working. We did the following. 1 Ipchains -F Tried telnet,ssh not working, 2 Chkconfig -level 12345 ipchains and rebooted the machine, then tried telnet,ssh its not working. Any Idea why it's not working? How will I fix this? Any help.
