We are having an issue with slow password prompts via SSH login on all of our SLES 11.2 boxes. The output from a ssh -v login attempt shows a delay here: This issue only happens on the first logon of the day; subsequent logons are normal. Adding the client's workstation hostname/IP to /etc/hosts, and setting "UseDNS no" in /etc/ssh/sshd_config has no effect. Both the client and server can resolve respective hostnames and IP's via nslookup and dig as well.
The peculiar side is that we also have a few SLES 10.4 boxes without this issue. Between these two versions, all of the applicable config files are identical. The only server-side difference we can see thus far is the version of OpenSSH, which is minor:
SLES 11.2 = OpenSSH_5.1p1, OpenSSL 0.9.8j-fips 07 Jan 2009
SLES 10.4 = OpenSSH_5.1p1, OpenSSL 0.9.8a 11 Oct 2005
Update 11/29/12: We performed a trace during the delay and our network team found something interesting. During the first logon of the day, there is a massive ldap query performed against the AD forest, as if a cache has expired and needs refreshed. This could explain why the delay only happens once a day. We are looking into the samba/winbind configs to see if there is a setting that controls when the cache expires. Perhaps the "winbind cache time" parm could be of value to us since these servers don't have routine ldap activity.
Hi,
I am using a remote storage service for backing up our data - we want to have a script run as part of a cron job which would do the backups from our local Linux machine to the service's Linux machine.
I want to use tar and ssh to do this (rather than mounting the disk and using cp) .... (5 Replies)
Hi All,
I've followed the exact same steps of how to setup and enable SSH user equivalent including the right permission, but when I "ssh" it still prompts for password. Could you help to see what I did wrong?
I appreciate any helps.

I have 3 Solaris 10 UNIX servers, the shadow and passwd file are all identical and are automatically sync every 5 minutes. A majority of the users do not have CLI access but rather use a menu. I currently have menu options that allows them to rlogin to another server and I need to have the... (1 Reply)
Hi,
I am using DSEE 6.3 to authenticate and authorize my Solaris 9 and 10 users. Everything works fine except password expiration. I use built-in global password policy for all users. The policy works well. However I could not find the right pam configuration in order to prompt users at ssh... (2 Replies)

Weak password: too short.
Try again.
You can now choose the new password.
A valid password should be a mix of upper and lower case letters,
digits, and... (2 Replies)
Can anyone give me a little clue on why the hard drive cache read timings on sles 9 is better then sles 11? The same hardware was used in both test. I even deleted the ata_generic module from initrd.
The speed difference is 10MB vs 5 MB

Hello forum,
I want to have a function to test for passwordless SSH setup. Pretty simple. However, what I'm finding difficult is to NOT return a password prompt to screen IF it's not in place.
Here's the function:
