Telnet problem

Li_7 — Mon, 18 Feb 2002 21:53:23 GMT

I???ve got HP-UX 11.00.

I could not use telnet to log into the server. Before that, there is no problem on the server. On the reboot, there are some error messages, erroras follow.

rpcbind: init_transport: check binding for tcp
rpcbind: init_transport: check binding for ticlts
rpcbind: svc_tli_create: t_getname failed; T_IDLE
rpcbind: svc_dg_create: could not get transport information
rpcbind: init_transport: Could not create rmtcall fd for ticlts
brian rpcbind: init_transport: check binding for ticotsord
brian rpcbind: init_transport: check binding for ticots
brian vmunix: NFS server (pid562@/net) not responding still trying
/usr/sbin/nfsd[627]: Setting STREAMS-HEAD high water value to 65536.

I can ping the server.

I try to telnet localhost through the console. It gives ???connection refused???.

# ps -fae | grep inetd
root 2331 576 0 21:01:39 ttyd0p2 0:00 grep inetd
# grep telnet /etc/inetd.conf
telnet stream tcp nowait root /usr/lbin/telnetd telnetd
# grep telnet /var/adm/inetd.sec
telnet allow
# netstat -rn | grep default
# grep telnet /etc/services
telnet 23/tcp # Virtual Terminal Protocol
#

I can ping default router.

There is no problem on the network. I can ping other computers in the network.

Lanscan gives follow:
0/0/0/0 0x001083FC4238 0 UP lan0 snap0 1 ETHER Yes 119

What does
netstat -a |grep telnet
say?

Connection refused sounds like it's not listening for telnet.

I notice netstat -rn does not have a default route. Are we limited to the local LAN or is the router doing proxy arp for us?

Can you ping this host from your starting point? If so try unplugging the network cable on the one you want to telnet to and make sure the ping to it fails. You could have a duplicate ip address and be hitting a Windows box.

Can you telnet to the local host while logged onto the console?

telnet 127.0.0.1

Well, the 'ps -aef | grep inetd' ouput doesn't show that the inetd daemon is working ! Check the reasons for that - inetd should be running.

Thanks.

You can ping the host.

telnet 127.0.0.1 gives "connection refused".

Hi,

Few questions for you.

First are there any users that have been able to telnet to the server since the last reboot?

How many user licenses do you have?

Can you telnet to a different server?

Is the inetd service actually running?

# ps -ef | grep inetd
root 604 1 0 16:47:24 ? 0:00 /usr/sbin/inetd

HTH

Hi,

From your ps output, your inetd daemon is not running at all to allow servicing of telnet requests.

# ps -fae | grep inetd
root 2331 576 0 21:01:39 ttyd0p2 0:00 grep inetd

Check that the following files exist and the startup script begins with a capital S ie. S500inetd.

# ls -la /sbin/init.d/inetd
-r-xr-xr-x 1 bin bin 1386 Oct 27 1997 /sbin/init.d/inetd
# ls -la /sbin/rc2.d/*inetd
lrwxr-xr-x 1 root sys 18 Mar 17 2000 /sbin/rc2.d/S500inetd -> /sbin/init.d/inetd

To start your inetd daemon in your current running environment, execute

# /sbin/init.d/inetd start

Hope this helps. Regards.
