I am using HPUX 11.00, and i have configured telnet, rlogin and ftp in /etc/inetd.conf.
All three was working fine.
Some 3 months before i am not able to connect through Telnet by using putty but able to connect by using telnet command available in Windows XP.
Then for past 2 weeks i am not able to connect through Telnet by using telnet command available in Windows XP.
Please find my configuration file:
# vi /etc/inetd.conf
ftp stream tcp nowait root /usr/lbin/ftpd ftpd -l-v-o
telnet stream tcp nowait root /usr/lbin/telnetd telnetd -b/etc/security.banner
login stream tcp nowait root /usr/lbin/rlogind rlogind -B /etc/security.banner
shell stream tcp nowait root /usr/lbin/remshd remshd
exec stream tcp nowait root /usr/lbin/rexecd rexecd
Solved! Go to Solution.

Re: Telnet issue in HPUX 11.00
Well, did you tell PuTTY to use telnet (as it's default is ssh)?
"Then for past 2 weeks i am not able to connect through Telnet by using telnet command available in Windows XP."
Is there a firewall in the mix somewhere that may be filtering (blocking) port 23 / telnet traffic? What error messages do you get when you try it.
Does telnet from anywhere else to the 11.0 box in question work?
Are the XP box and HPUX on the same subnet or different?

Re: Telnet issue in HPUX 11.00
Whenever you try to connect, what message do you get after usuing the user name and password? Or do you get any prompt at all?
Regards,
Jaime.

Re: Telnet issue in HPUX 11.00
What is the error message you are getting when trying to telnet?
Use netstat to check that inetd has read inetd.conf and has opened a socket for port 23 (telnet) and this is in LISTEN status.
# netstat -a |grep telnet
Enable inetd -l and check syslog.log to see if any critical error is logged when telnetd starts.
# lsdev
Look for "tels" and "telm" in the third field.
Check the master driver's device file:
# ll /dev/telnetm
Regds..

Re: Telnet issue in HPUX 11.00
See the attached picture of the PuTTY configuration dialog - you *did* select telnet/port23 didn't you?

Re: Telnet issue in HPUX 11.00
inetd -k
inetd -l
after doint this, please login to this server and run
tail -f /var/adm/syslog/syslog.log
as you try to telnet to it from another server to see if your request is even reaching the server.
UNIX because I majored in cryptology...
