I don't think he's talking about password aging.

He *seems* to be saying either:
a) he's timing out at login if he doesn't answer the password prompt quick enough, or
b) the actual "password" command is timing out.

I've never heard of / seen either of the above...

so, clarification is needed.

When does this occur, and if it's during login, how are you connecting (telnet, ssh, etc..) and what terminal emulator (if any) are you using...

Version of the OS, trusted or non-trusted?

This is just a "thought"....

It sounds like a network setting has been tuned down.
Does this happen on every server? or just one?
Has anyone done any networking tuning on this server lately with the ndd command?

Do a man ndd
Check the settings for tuneables that affect the length of tcp timeout. Compare to other boxes not having this problem. If you find something set too low...adjust it.

Example to check setting:
ndd -get /dev/tcp tcp_deferred_ack_interval

Hope this helps,
Rgrds,
Rita

Hi Oldschool,

This happens during login and your a) option is exactly what i am facing.

Version of OS is 11.23 and it is in trusted mode.

We have disabled telnet access, so only via ssh login anyone can login and this happens with ssh... and the terminal emulator i use is putty.

Hi Rita,

I don't think network tuning has been done.

The out put of the command that you gave was 50. And, i checked with a box which was working fine, the output of which was also 50.

This is a 3-node cluster and the problem is there with all the 3 servers.

Thanks !

Sridhar,

If you can login at the console, try calling:

/usr/lbin/getprdef -t

This gives the Trusted System settings for the following:
umaxlntr max number of consecutive unsuccessful logins allowed
tmaxlntr max number of consecutive unsuccessful logins allowed
per terminal
dlylntr time delay between unsuccessful login attempts
lntmout login timeout in seconds

The setting for lntmout usually =0 (zero). Which means the system default, about 30 seconds, applies. If the value is not zero, try setting it using the following:

/usr/lbin/modprdef -m lntmout=0
