1. So, have inetd started and listened for telnet connections? It seems
like your inetd/ftp trying to bind to 'old' ctc ip address only (and
localhost).
2. Check the routing table.
3. Check the routing table twice :)

Subject: Re: Removed CTC, kept ETH... SSH still works, TELNET and FTP
don't
Oh sorry, I should have said that also :
Yes, I've been able to ftp from within the linux once
connected in ssh...
[EMAIL PROTECTED] root]# ssh lnxprod
[EMAIL PROTECTED]'s password:

Have a lot of fun...
lnxprod:~ # ftp lnxprod
Connected to lnxprod

ftp>
... but I haven't been able to telnet lnxprod or even
localhost from within :
lnxprod:~ # telnet lnxprod
Trying 172.16.8.34...
telnet: connect to address 172.16.8.34: Connection
refused
lnxprod:~ # telnet localhost
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection
refused
Telnet is started by inetd while ftp is in standalone
lnxprod:/etc # grep telnet inetd.conf
# If you want telnetd not to keep-alives (e.g. if it
runs over a ISDN
# uplink), add -n. See 'man telnetd' for more details.
telnet stream tcp nowait root /usr/sbin/tcpd
in.telnetd
# Try telnet localhost systat and telnet localhost
netstat to see that
regards,
Eric.
