now Im unable to login with my regular username, or to su - to it
[root@xxxxxxx pam.d]# su - jimc Segmentation fault [root@xxxxxxx pam.d]# su jimc Segmentation fault [root@xxxxxxx pam.d]#
the segfault happens when su-ing from joe to bob,
Also - on the X session still running there, where previously opened 'joeuser' windows are present, the bash prompt changed to "[I have no name!@xxxxxxx]", and xterm title now shows 500, my userid from /etc/passwd (which is dated 4/13, so presumably un-mangled).
I havent yet tried a reboot to see if this is transient, despite my ability to
ssh into the box (as root only).
I was messing around with SAMBA, trying to get it to accept password entered at smbclient's prompt.
after adding '-d 2' to /etc/sysconfig/samba: SMBDOPTIONS, I determined I had a missing smbpasswd file, so I made one:
mksmbpasswd.sh < /etc/passwd > /etc/samba/smbpasswd. log showed progress, file found, but passwd not accepted.
then things went astray: I wasnt getting further, so I checked pam;
rpm -V pam showed a change:
rpm -V pam .......T c /etc/pam.d/other S.5....T c /etc/pam.d/system-auth .......T c /etc/security/access.conf
so I forced a reinstall (several times) - I eventually noticed the system-auth.rpmnew,
but only after I renamed the modded file, so Im not sure of the order or importance
of my changes.
BTW - is it normal/expected that an 'rpm -i --force $pkg' would fail to overwrite
modified files ?
Also, Im seeing unexpected diffs between old file, and new - it
[root@xxxxxxx pam.d]# diff system-auth system-auth-hold 4,6c4,6 < auth required /lib/security/$ISA/pam_env.so < auth sufficient /lib/security/$ISA/pam_unix.so likeauth nullok < auth required /lib/security/$ISA/pam_deny.so --- > auth required /lib/security/pam_env.so > auth sufficient /lib/security/pam_unix.so likeauth nullok > auth required /lib/security/pam_deny.so 8c8 ...
This looks suspicious; like an install-script substitution didnt happen.
CAN ANYONE SHED ANY LIGHT ON THIS ?
even WAGs are encouraged.
