Hello friends,

I recently ran an upgrade on my system which is debian sid(most of it) during the upgrade I noticed that libc6 version is also being upgraded .

After the upgrade I noticed that my machine rejects any NIS login. It allows login through local accounts though.

I have attched two sections of auth.log file

here user shashank is a NIS user. If I do ypcat passwd or passwd.byname I get the entire passwd db from NIS sever. also ypwhich points to correct ypserver. We have only one NIS server on the network and no NIS slaves running.

My experience with NIS is not very vast.

I went through google but those docs did not help me much.

version of libc6 running on the system is 2.3.2-3 version of nis on system is 3.9-6.3 ========================================================================================== Aug 29 00:33:53 gnu PAM_unix[2172]: authentication failure; (uid=0) -> shashank for ssh service Aug 29 00:33:55 gnu sshd[2172]: Failed password for shashank from 158.144.42.200 port 35335 ssh2 Aug 29 00:34:02 gnu PAM_unix[2172]: check pass; user unknown Aug 29 00:34:04 gnu sshd[2172]: Failed password for shashank from 158.144.42.200 port 35335 ssh2 Aug 29 00:34:12 gnu PAM_unix[2172]: check pass; user unknown Aug 29 00:34:15 gnu sshd[2172]: Failed password for shashank from 158.144.42.200 port 35335 ssh2 Aug 29 00:34:15 gnu PAM_unix[2172]: 2 more authentication failures; (uid=0) -> shashank for ssh service Aug 29 00:34:32 gnu PAM_unix[2174]: check pass; user unknown ========================================================================================== Aug 29 17:19:13 gnu login[12149]: FAILED LOGIN (1) on `tty1' FOR `shashank', Authentication service cannot retrieve authentication info.
