Problems with telnet

Carme Torca — Wed, 15 Feb 2006 04:58:29 GMT

Hi,

I have installed a new computer, I am in console and I have net configured, but when I do a telnet loopback o telnet itself, it doesn't works ok.

Does anyone could help me?

#telnet 10.2.3.3
Trying...
Connected to 10.2.3.3
Escape character is '^]'.

(it hangs here)

# netstat -a |grep -i telnet

Hi,

check the speed of your network card and the port setting on your switch.

It is best to put these on the same settings

Hi,

1. Check your hostname is proper.
# hostname
# cat /etc/hosts
Both should be similar

2. Check /etc/nsswitch.conf file.
See you have set proper resolution order.

3. Check /etc/rc.config.d/netconf
For proper NIC configuration.

4. Use "linkloop" command to see if you are able to ping the switch port (cable may be bad)

5. Check your NIC port and switch port setting are in sync. Both should have similar speed settings, Duplexing etc.

Hope that resolves.

Regards,

I think that this problem is related to name resolution. Check your /etc/hosts file (add your computer there), your DNS configuration in /etc/resolv.conf and /etc/nsswitch.conf.
