After upgrade Passport to 1.5.0, can't login using root to CLI on SSH

Question

Hi!

I upgraded a bunch of Passports to the latest 1.5.0 code (82001329_L.bin) and noticed this issue after.

Before the upgrades, I could login with "root" over SSH to port 22 of the Passport, and I would be rewarded with a CLI. However, after the upgrade, I can no longer do so.

The root user works fine on the Web, and also via "SU -" if I setup another CLI user. The messages file says:

Nov 20 13:01:08 Digi_Passport pam_local_auth: session opened for user root by (uid=0)
Nov 20 13:01:08 Digi_Passport sshd: LOCAL - SSH authentication for 'root' passed.

but the SSH client sees this instead:

unixbox$ ssh -l root 10.2.3.4
root@10.2.3.4's password:
Permission denied, please try again.

The config didn't change, as it was a simple "Upgrade Firmware", and post reboot this is the case. PAM/SSHD seem ok with the password, but the user can't login. SSH is working otherwise, like I said if I create a new user with CLI rights, and I SU from there...

And, you probably know, the /etc/sshd_config contains the line:
#PermitRootLogin yes

What's going on?

Thanks!
Ian.

Answer 1

1. Change the “PermitRootLogin” option to yes and take out the “#” in /etc/ssh/sshd_config
PermitRootLogin yes

2. run “saveconf” command in the CLI.

3. Restart “SSHD” by running the following command in the CLI
# service sshd restart
Or simply reboot the system again.

Hi RonK,

For the record, I needed to reboot the box in order for the change to take.  The service restart didn't work for this keyword.

Thanks for your information!
