However, the above set always conincides with a pair of related messages including the segfault. The PID is always just a few numbers higher. The times at which the log entries occur are at the same time. The user names logged by PAM_smbpass are also always identical: PAM_smbpass[30864]: username [root] obtained kernel: sshd[30864]: segfault at 00000000 eip 00000000 esp bfdbf73c error 4 It seems as if the password itself might be the cause for the segfault. The real bug could be in PAM_smbpass, but sshd should really not segfault. -- .''`. martin f. krafft <madduck@d.o> Related projects: : :' : proud Debian developer http://debiansystem.info `. `'` http://people.debian.org/~madduck http://vcs-pkg.org `- Debian - when you have better things to do than fixing systems
