I'm trying to run check_by_ssh against my localhost (for consistency purposes.) I'm using forced command execution with ssh:
`cat /home/nagios/.ssh/authorized_keys2` command="/home/nagios/bin/check_by_ssh.sh" ssh-dss AAAAB3N<snip> nagios_check_by_ssh /usr/lib/nagios/plugins/check_by_ssh -i /etc/nagios2/keys/check_by_ssh -l nagios -H localhost -C 'Disk_Space -m /root -w 15% -c 10%' -t 20 This check works fine (same authorized_keys, same script) on remote hosts, but segfaults against localhost. Localhost kernel: [5081242.311916] check_by_ssh[15109]: segfault at 0000000000000000 rip 00002b68aaa130f0 rsp 00007fff00450888 error 4 As the nagios user I run: `ssh -v -i /etc/nagios2/keys/check_by_ssh localhost 'Disk_Space -m /root -w 15% -c 10%'` <snip> debug1: read PEM private key done: type DSA debug1: Remote: Forced command: /home/nagios/bin/check_by_ssh.sh debug1: Authentication succeeded (publickey). debug1: channel 0: new [client-session] debug1: Entering interactive session. debug1: Sending environment. debug1: Sending env LANG = en_US.UTF-8 debug1: Sending command: Disk_Space -m /root -w 15% -c 10% debug1: client_input_channel_req: channel 0 rtype exit-status reply 0 debug1: channel 0: free: client-session, nchannels 1 debug1: Transferred: stdin 0, stdout 0, stderr 0 bytes in 0.0 seconds debug1: Bytes per second: stdin 0.0, stdout 0.0, stderr 0.0 debug1: Exit status 1 `ssh -v -i /etc/nagios2/keys/check_by_ssh otherhost 'Disk_Space -m /root -w 15% -c 10%'` debug1: read PEM private key done: type DSA debug1: Remote: Forced command: /home/nagios/bin/check_by_ssh.sh debug1: Authentication succeeded (publickey). debug1: channel 0: new [client-session] debug1: Entering interactive session. debug1: Sending environment. debug1: Sending env LANG = en_US.UTF-8 debug1: Sending command: Disk_Space -m /root -w 15% -c 10% debug1: client_input_channel_req: channel 0 rtype exit-status reply 0 DISK OK - free space: / 320 MB (67% inode=96%);| /=159MB;407;431;96;479 debug1: channel 0: free: client-session, nchannels 1 debug1: Transferred: stdin 0, stdout 0, stderr 0 bytes in 0.0 seconds debug1: Bytes per second: stdin 0.0, stdout 0.0, stderr 0.0 debug1: Exit status 0 The only difference is the output from check_by_ssh.sh on the remote host (and an exit code.) Since the check_by_ssh.sh (/home/nagios actually) was rsynced from localhost to otherhost it seems it should be ok. If I export SSH_ORIGINAL_COMMAND and run check_by_ssh.sh on localhost it works ok, so I don't think it's the script. Nagios is reporting status as "(Return code of 139 is out of bounds)." This is on Ubuntu 6.10, all versions of everything (ssh client, server, nagios-plugins, etc.) are the same. Any ideas, I'm kind of at a loss... mark ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
