nagios plugin check_pgsql can’t handle all valid database names

Leave a Comment / Bucardo, Nagios / By /

I found a problem with the check_pgsql Nagios plugin last week. It can’t handle names such as freshports.org. It’s a valid database name, as witnessed here: $ psql -l | grep freshports freshports.old | dan | SQL_ASCII | C | C | freshports.org | dan | SQL_ASCII | C | C | But it doesn’t work: $ /usr/local/libexec/nagios/check_pgsql -H slocum -l www -d freshports.org check_pgsql: Database name is not valid – freshports.org Usage:

If you see this message when trying to svn up: then you are missing a subversion compile option. Try this command: cd /usr/ports/devel/subversion && make config Then make sure this option is checked: [X] SERF WebDAV/Delta-V (HTTP/HTTPS) repo access module Then recompile subversion with one of these two commands: portupgrade -f subversion Or portmaster subversion

mounting the FreshPorts chroot within a jail

Leave a Comment / ezjail, FreeBSD, FreshPorts, Jails, Open Source / By /

In my work on FreshPorts, I’ve learned more than the average non-committer about the FreeBSD ports tree and its oddities. Just about everything learns about a port it gets from ‘make -V’. Even this method can be fraught with difficulty. In an attempt to get the fairest information possible, FreshPorts uses a chroot solution, first proposed by Ryan Steinmetz . Previous posts about this particular solution can be found in the FreshPorts blog.

bad ifconfig leads to no pings

I had a Bacula job fail today: Is bacula-sd running on crey? Yes it is. Can I telnet to port 9103 on crey? Yes, I can: $ telnet 10.5.0.20 9103 Trying 10.5.0.20… Connected to crey.example.org. Escape character is ‘^]’. What about from the nyi-fd server? Can I telnet from there? $ telnet 10.5.0.20 9103 Trying 10.5.0.20… telnet: connect to address 10.5.0.20: Operation timed out telnet: Unable to connect to remote host I started

Accessing every jail from a VPN

Leave a Comment / Jails, Open Source, OpenVPN / By /

I’ve been meeting a few challenges with running an instance of bacula-fd in each of my jails. Most of them are related to networking. Perhaps my deployment strategies are imposing too many restrictions. The challenges arise on the jail hosts which are not behind my firewall at home. Each of those servers is accessible through a VPN, but the individual jails on those servers are not. The backup of the jail host is
