SSH login will state after password entering "Unable to get valid context for root"
Last modified: 2012-05-27 07:11:33 EDT
Description of problem: I am unable to SSH into the system. I will be greeted with password prompt, but after providing one I get "Proken Pipe" and "Unable to get valid context for root" message and will get kicked out. Version-Release number of selected component (if applicable): Kernel 3.4.0-0.rc6.git3.1.fc18.x86_64 How reproducible: Always on that system, but not on other machines I have. Steps to Reproduce: 1. Try to login over SSH; Actual results: Locally trying will get me "Broken Pipe" message and remote one: [root@haskaa ~]# ssh 192.168.20.8 root@192.168.20.8's password: Unable to get valid context for root Last login: Sun May 20 07:20:53 2012 from haskaa Connection to 192.168.20.8 closed. [root@haskaa ~]# Expected results: Terminal prompt. Additional info: I removed and reinstalled SSH server, but nothing changed. Also, I have updated several kernel releases, but still the same situation. [ivo@ragana ~]$ rpm -qa|grep ssh libssh2-1.4.1-2.fc18.x86_64 openssh-askpass-5.9p1-22.fc18.x86_64 openssh-5.9p1-22.fc18.x86_64 openssh-server-5.9p1-22.fc18.x86_64 libssh-0.5.2-1.fc17.x86_64 trilead-ssh2-213-9.fc17.noarch openssh-clients-5.9p1-22.fc18.x86_64 ganymed-ssh2-210-11.fc17.noarch [ivo@ragana ~]$
This sounds like an SELinux label issue. You might want to relable your filesystem.
Yes. ps -eZ | grep ssh If it is not running as sshd_t, you probably have a labelling issue. # touch /.autorelabel; reboot Should fix the systems labeling.
Thanks, it did the trick. Before "touch /.autorelabel; reboot": [root@ragana ~]# ps -eZ|grep ssh system_u:system_r:kernel_t:s0 524 ? 00:00:27 sshd [root@ragana ~]# and after: [root@ragana ~]# ps -eZ|grep ssh system_u:system_r:sshd_t:s0-s0:c0.c1023 1125 ? 00:00:00 sshd [root@ragana ~]# I have SELinux in permissive mode. Why it should affect my system work?
