comment Can't create/write to file '/tmp/#sql_xxxx.MYI' (Errcode: 13)
thanks for including the mysqladmin output. I've now used this to donate a dedicated tmpdir for mysql, adding a little security.

comment Check to ping google from host in check_mk using WATO
Errors from ping wil be printed prior to the echo. When that happens, your local check section of the agent output will go to hell

comment ntpd default rate limiting?
If the servers fall back to the stratum 10 local clock it is hardly an issue if the monitoring, just because it noticed and did alert. :>

comment Check to ping google from host in check_mk using WATO
It's not possible to define a check like this from the server side since the agent is not designed to ever accept external input.

You should just make one addition and suppress error messages from the script as they could break the local checks section, badly.

comment How do I non-interactively update FreeBSD system (and ports)?
No it won't destroy a newly installed system. He's worrying you'll blow up your systems and obviously didn't read any of the bits about nightly images.

comment Is it necessary to burn-in RAM for server-class hardware?
except for all the incidents of people who actually found errors, as shown in the thread. Also, if it's not obvious, there is a difference in getting the parts swapped before taking a server into production or replacing ram on a DB server that runs in 24x7. Unless pretend it's a "Grown error" and everyone else is just old and doing cargo cult stuff, but it's still gonna cause losses to have a prod server offline.

comment Trying to set up SFTP only in a chroot jail for one user
Hi Devator, many kudos for the trick with setting the homedir to /incoming in /etc/passwd - i had set it to the chroot base dir (worked); now setting to incoming the users are in a writeable directory as it makes sense for them. From my reading of docs and howtos I think you're the only person who got that right[tm]. Thanks so much!
