Description of problem:
new red hat 7.1 installation. able to telnet into machine fine. except
for the red hat machine itself...cannot telnet out to any machine (by name
or ip address). can ping any machine by its name or ip address, but when
trying to telnet out get "no route to host message". similar machine
running 7.0 has no problem. network card running fine, netscape running
fine, ping running fine, network parameters set up fine. default search
hosts, dns. person in office next door having similar issue. we give
up! any clues? basically cannot telent to any machine other than the
local machine (but can telnet in fine).
Steps to Reproduce:
2. open hostname (or ip)
3. no route to host message
Actual Results: still cannot telnet out...though can ping to the machine.
Expected Results: login prompt from remote machine
I, too, have this problem. I telnet out and get a message that I am connected to
the host machine, it sits for several seconds, and then says that the
remote host closes the connection. I am never asked to logon...
email@example.com: This sounds like /etc/hosts.allow is denying your
connection. You may check /var/log/secure and /var/log/messages.
this has absolutely nothing to do with hosts.allow....
like i said...i can telnet to the machine from anywhere (in the world). cannot
telnet out to anywhere (in the world). can telnet out from any other machine.
No problems here. Are you sure you do not have any firewall settings on
your local machines? ipchains -L ???
$ sudo rpm -ivh
