Not able to login from putty to server

Postby rameez.amjad4 » Fri Oct 19, 2018 5:09 pm

Good Day,
i have a very rare issue today i install Vicibox 8.1.2 and i followed following steps:

1) Os-install
2) Yast lan
3) Zypper up -y

and when i rebooted system and tried to login to server via putty on the local network i am not able to login as root with the password that i set, but when i login directly to server using root it gets logged in :-(

Need Assistance, Thanks.

Try downgrading openssh.

If I reinstall system and do not use update 'zypper up - y' still installation will be done smoothly or it is necessary updating if not then I can reinstall system.
Please update, thanks.

Probably would work. But you probably could just use zypper to downgrade openssh to a slightly lower revision without a reinstall. But we've not had this problem yet so I can't be sure or provide the specific instructions.

https://unix.stackexchange.com/question ... ic-version

get the versions available
Code: Select all
zypper se -v openssh


after choosing the version you want:
Code: Select all
zypper in -f <package-with-version>


For instance, I executed the check on a server running 8.0.1 and got:
Code: Select all
i+ | openssh                   | package    | 7.3p1-1.1    | x86_64 | (System Packages)


So it's possible that this would be valid:

Code: Select all
zypper in -f openssh=7.3p1-1.1
