Unhappy telnet problem (getnameinfo.)


I can't telnet to my linuxbox and is in the same network. And I already haven't set hosts.allow and hosts.deny. When I telnet to my box and reply is "getnameinfo." then closed. What is the problem of my box?

Thanks!

Can you ping the IP address?
netmasks set the same?
#ifconfig -a

Is the telnet Daemon running?
# ps -eaf | grep telnet
look for in.telnetd

If so Can you telnet to the IP address?
If you can telnet the IP check out all name resolution stuff

Also check your /etc/hosts file. take out the alias to your actual hostname and the localhost. Put your hostname and IP address on a seoarate line.

and /etc/inittab.conf for the line
hosts files dns nis nis+
make sure files comes before dns. This is your name resolution order

Also check /etc/hosts.conf I think it is. This will have a line containing order and bind. Youll have to check the man pages for details cause I cant remember.

If you can login as a user but cannot login as root check man page on /etc/securetty

Hope this helps?

gethostbyname is a system call. I dont uderstand these things but can you telnet 127.0.0.1? perhaps try this first. If you cant then either telnet is not running or its broken somehow. (not all installed?
try
# rpm -qa | grep telnet
and check you have all the packages installed.

# setup
at the command line and check all the system services.

I am not sure this rpm packages can/can't running RH7.1, does RH also have this problem? If yes, did you find the patch from RH sites?
