Telnet : Configure the login retry count

thelink123 · 01-06-2011, 07:46 AM

Hi,

I have two servers running Linux 2.6.9 kernel.

When i telnet to server1 , the telnet will be disconnected only after 3 login failures. While, when i telnet to server2, telnet will be disconnected after the first login failure. I expect server2 to behave the same way as server1 when telnet is executed.

Kindly tell me where i should tweak my servers so that i could achieve what i expect.

Thanks,
TheLink

Hi,

Have a look at /etc/login.defs for LOGIN_RETRIES

Hi, Bathory,

I tried both LOGIN_RETRIES and LOGIN_TIMEOUTS in /etc/login.defs on my fc14 machine. Neither of them seems to work. LOGIN try always terminates the connection at the 4th try. Any suggestions? Thank you.

Hi,

Since you're using fc14, those variables are overwritten by pam.
You can open the file /etc/pam.d/system-auth, look for the line containing pam_cracklib (similar to the following):

Quote:

password requisite pam_cracklib.so try_first_pass retry=3

and change the retry number to your liking
