Qmail PLAIN SMTP Auth failure, after upgrade to FreeBSD 9/10x, vpopmail,

1 Reply

vpopmail[37658]: vchkpw-smtp: vpopmail user not found karen@:95...*

After upgrading certain shared servers to FreeBSD 10x i came to the follwing conclusion:

chmod ug+s /usr/local/vpopmail/bin/vchkpw

The servers needed that after i manually selected SMTP AUTH in the make config of the port:
/usr/ports/mail/qmail

Or the qmail user couldnt execute it right and created MASS CHAOS in the building where i worked at that moment. Ppl couldnt auth right with authenticated SMTP, vpopmail.

Cacti not filling certain RRDTool db’s on FreeBSD

Hi,

We reinstalled one of our nameservers with BSD 10.

Ive syced the RRA files over from RRDTool using the follwing command:
rsync -avz /usr/local/share/cacti/rra/ usert@hostname.nl:/home/cacti/rra/.
rsync -avz /local/directory username@kwomkwommr.nl:/destination/dir/.

it kept on running on a high load if it ran the poller.php and cmd.php from cacti on it.

I coulda dig into it and maby? solve it, but we are running into like 400+ hosts and alotta dataqueries, so i knew spine is a cleaner and better way to poll hosts, so why not give it a try…

Ive gone to Console > Settings > Poller tab > And put it on Spine instead of cmd.php
It did not work instant, i had to edit the settings file /usr/local/etc/spine.conf and put in the MySQL database details

After this it filled 3/4 of the RRD database, but a few hosts kept showing there down, so i didnt get what was going on. After a while i discovered a chmod on the spine binairy was wrong.

So after a quick:
chmod a+s spine

On the binairy file it was sorted, and the 4 hosts that where showing there down where “up” and recovering again. Very wierd… still dont know why a few hosts needed this. These werent hosts that had any special plugins… lol

Hope this will help u on your quest to polled hosts,

WordPress drama – wp-login.php

Hi,
We experiece alot of occasions lately that ppl are trying to crack a wordpress “admin” login. to post spam or something on a wordpress blog. Change the standard username / password if u wanna be safe and dont wanna have a hosting company complain at u. We have been experiencing a higher load then useual on our shared servers lately.

If someone wont respond then we take action and use one of the following samples:

Create a .htaccess file or edit it, and put in the following:

<Files wp-login.php>
AuthUserFile /home/vhosts/kwomkwommr.nl/www/.htpasswd
AuthName “Private access”
AuthType Basic
require valid-user
</Files>

Generate a .passwd file on the desired location:
htpasswd -c /home/vhosts/kwomkwommr.nl/www/.htpasswd username

I know, i havent done anything like that yet, i dont care till i will be spammed till a load of 10, and then ill see if i use this or use any of the following options on the WordPress FAQ
