I am trying to login to the machine. I get type in login id (root, normal user), it takes it and then takes a long time to display the password prompt. once u type the password the login is quick. what could be the issue?

Thanks

Joe

Shalom Joe,

Three possible factors here:

Version of Secure Shell on the server
swlist -l product | grep -i secure

how fast host resolution occurs on the client machine: /etc/resolv.conf

Strong random number generation on the server to do the encryption more quickly.

11i v1 only. Its built into 11i v2. Its not available for 11.00 at all.

this is the output from swlist
# swlist -l product|grep -i secure
openssl A.00.09.07-d.010 Secure Network Communications Protocol

Thanks

Run this command:

swlist | grep -i "RNG"

I'm betting you don't have the Strong Random Number Generator (or it is not functional, if installed).

This is what i get....

swlist -l fileset -a state |grep -i "RNG"
openssl.OPENSSL-PRNG configured
# prngd
prngd.prngd-RUN configured

we have checked and dns is fine.

Thanks
