[rancid] error after migrating to new server

[Andrew Meyer]

Recently we have migrated from our in house setup to AWS.  Rancid is installed on Amazon Linux 2, but i'm seeing this issue in the logs:

Short answer, yes. But "par" is troublesome.

RANCiD needs a program by that name for "parallel command processing", but the name conflicts with other software packages, particularly on Ubuntu linux as I recall. I don't know if it conflicts with Amazon's linux.

I renamed it to rancid_par back when I built the Red Hat packages of RANCiD 3.4.1, but I haven't done so in more recent packages because I don't need any of the other programs named "par" on any of my Red Hat boxen.

also, it seems you installed it under /usr/bin, best practices for rancid & package management in general is not do this. perhaps install it under the rancid user's homedir & make sure $HOME/bin is in your $PATH first. second option is that you used a vendor provided rancid package instead of building from source, which might not include par. third option is that your cron or whatever scheduler you're using is does not have par in it's $PATH.

Is this a perl/python or something else command?  I think I found the package in Amazon Linux.

The "file" command says it's an executable image, not a script.

[***@gitdrome ~]# file /usr/libexec/rancid/par

/usr/libexec/rancid/par: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=968bbb9325486639b0fd1294bebcfef7c67317ed, stripped

If you've found the correct par (and not one of the other programs of the same name) then like Nick said you need to make sure it's in the PATH of the user executing rancid-run.

its a command that comes with rancid. my guess is one of

- you copied rancid from another machine and missed it
- the pre-built package you installed is broken
- you copied rancid.conf from another machine and its PATH doesnt match,
so it cant find par.
- you deleted it somehow
- you're using an old version of rancid, when par was a perl script, and
the interpretter line is wrong
- par lacks executable mode bits

[Andrew Meyer]

I fixed.  Had to create a symlink from, /usr/bin/par to /usr/libexec/rancid/par.
Thank you!
