telnet problem: temporary failure in name resolution illegal seek in fedora core 6

bv_uma · 01-30-2007, 08:50 AM

dear friend
I have installed fedora core 6 recently in my LINUX server in my LAN. i have configured my server's eth0 for local networking with IP address 172.16.12.2.

I am unable to access this fedora core 6 linux server
172.16.12.2 from any PC [windows XP based] inj LAN using telnet.
I get the following error:
"Temporary Failure in name resolution .... illegal seek".

Can you help me out.
Thanks and regards

That error sounds strange, but telnet does not become enabled by default. SSH is enabled by default, and is much better than telnet, as the traffic is encrypted.

Your error makes little sense, as telnet 172.16.12.2 doesn't ask for and DNS resolution. It should still fail, but it shouldn't spit a DNS error.

Peace,

I've had the same problem with telnet server in FC6.
One solution is to use krb5-telnet server instead of telnet server.
Open service configuration window. Go to On Demand Services tab. Remove the checkmark, if any, beside 'telnet'. Put checkmark beside 'krb5-telnet'. Save the settings. Then, switch to Background Services tab and select xinetd and restart it.
I hope it'll fix your problem.

That is because of the name resolving of client which want to access to telnet server.
The solution here is: Open the hosts file (/etc/hosts in linux, C:/Windows/system32/drivers/etc/hosts in Window) of the machine which telnet server is running. Add the ip address and the relevant name of the host which want to connect to telnet server in. The telnet will work fine.
