Hi,
I have NIS master server on RHEL 7.6. It is using SHA512 as hashing algorithm by default. The users which are created on SHA512, are not able to login to a Solaris 10 with "Sun_SSH_1.1, SSH protocols 1.5/2.0". It gives segmentation fault. But some users were migrated from old NIS and those passwords are short (not SHA512).
Now, there is a requirement of one user needs access to this old Solaris 10 server. This user was created recently, so its password is SHA512. Is there anyway, I can reset his password on RHEL NIS master server, with older hashing?
I don't want to change default behavior of NIS server, for all users.
Please suggest.
Thanks

Here's a good HOWTO ref to the openssl cli tool https://www.madboa.com/geek/openssl/...password-entry and here's a soln https://unix.stackexchange.com/quest...n-command-line
Just scroll down to that example cmd and read the notes

I guess that is not impossible (replacing the hashing algorithm), but I would rather try a different way.
From the other hand the ssh protocol error is not related to that hashing algorithm. see for example here: https://askubuntu.com/questions/1112...r-than-ssh-1-5
Segmentation fault is also hardly related to that.
I would try to fix that ssh config, and probably I would try to create a local user if there was no better way.
