Hi,
SK> When i try to connect to my Red hat machine from another machine thro
SK> telnet. It takes much time to get the login prompt. I also can't login as
SK> root.
One of the reason must be problem in resolving name of the machine
from which you are telnetting. If you are telnetting from other
machine, the simple way of making it faster is to add lines in
/etc/hosts file like:
192.168.0.2 client.machine.com client
This way the Linux server will know that client, from where you are
telnetting and it should work even if your dns is not configured yet.
Of course you would have
order hosts,bind
in /etc/host.conf which allows your linux server to look in /etc/hosts
file with more priority than Bind (DNS system) If you are using this
for corporate network, hosts files wshould be easier but if you are
talking about Big networks, then DNS should be flexible way.
Telnetting using root shall be provided using following entries in
/etc/securetty
ttyp0
ttyp1
ttyp2
...
This way you can allow as many no. of ROOT-Telnet.
Hope this helps.
