Public bug reported: I added "PermitUserEnvironment Yes" in sshd_config file, and the server cannot start at all. Every attempt to start the server results in such error messages at the end of this report.
The reason is I used 'Yes', which should be 'yes'. It is hard to find, since when starting the server, it seems OK: $ sudo /etc/init.d/ssh start [sudo] password for tux: Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service ssh start Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the start(8) utility, e.g. start ssh ssh start/running, process 5780 It does not report it as a config file error. -------------- Syslog message: Jan 4 21:21:16 Neverland kernel: [ 5271.135175] init: ssh main process (5780) terminated with status 255 Jan 4 21:21:16 Neverland kernel: [ 5271.135236] init: ssh main process ended, respawning Jan 4 21:21:16 Neverland kernel: [ 5271.147909] init: ssh main process (5783) terminated with status 255 Jan 4 21:21:16 Neverland kernel: [ 5271.147950] init: ssh main process ended, respawning Jan 4 21:21:16 Neverland kernel: [ 5271.155092] init: ssh main process (5786) terminated with status 255 Jan 4 21:21:16 Neverland kernel: [ 5271.155127] init: ssh main process ended, respawning Jan 4 21:21:16 Neverland kernel: [ 5271.163840] init: ssh main process (5789) terminated with status 255 Jan 4 21:21:16 Neverland kernel: [ 5271.163873] init: ssh main process ended, respawning Jan 4 21:21:16 Neverland kernel: [ 5271.171317] init: ssh main process (5792) terminated with status 255 Jan 4 21:21:16 Neverland kernel: [ 5271.171348] init: ssh main process ended, respawning Jan 4 21:21:16 Neverland kernel: [ 5271.178720] init: ssh main process (5795) terminated with status 255 Jan 4 21:21:16 Neverland kernel: [ 5271.178764] init: ssh main process ended, respawning Jan 4 21:21:16 Neverland kernel: [ 5271.186037] init: ssh main process (5798) terminated with status 255 Jan 4 21:21:16 Neverland kernel: [ 5271.186080] init: ssh main process ended, respawning Jan 4 21:21:16 Neverland kernel: [ 5271.194536] init: ssh main process (5801) terminated with status 255 Jan 4 21:21:16 Neverland kernel: [ 5271.194579] init: ssh main process ended, respawning Jan 4 21:21:16 Neverland kernel: [ 5271.203290] init: ssh main process (5804) terminated with status 255 Jan 4 21:21:16 Neverland kernel: [ 5271.203331] init: ssh main process ended, respawning Jan 4 21:21:16 Neverland kernel: [ 5271.210991] init: ssh main process (5807) terminated with status 255 Jan 4 21:21:16 Neverland kernel: [ 5271.211026] init: ssh main process ended, respawning Jan 4 21:21:16 Neverland kernel: [ 5271.217402] init: ssh main process (5810) terminated with status 255 Jan 4 21:21:16 Neverland kernel: [ 5271.217424] init: ssh respawning too fast, stopped ProblemType: Bug DistroRelease: Ubuntu 11.10 Package: openssh-server 1:5.8p1-7ubuntu1 ProcVersionSignature: Ubuntu 3.0.0-14.23-generic 3.0.9 Uname: Linux 3.0.0-14-generic x86_64 NonfreeKernelModules: fglrx ApportVersion: 1.23-0ubuntu4 Architecture: amd64 Date: Wed Jan 4 21:20:43 2012 InstallationMedia: Ubuntu 10.10 "Maverick Meerkat" - Release amd64 (20101007) SSHDConfig: Error: command ['gksu', '-D', 'Apport', '--', '/usr/sbin/sshd', '-T'] failed with exit code 255: SourcePackage: openssh UpgradeStatus: Upgraded to oneiric on 2011-10-14 (81 days ago) ** Affects: openssh (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug oneiric running-unity -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/911753 Title: Wrong directive in config file cause server to crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/911753/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
