Nagios – Check BigIP F5 load

As for the previous F5 plugin, I just found this old Nagios plugin of mine, sitting in a directory, taking dust.

As usual, I’m not a programmer, so I just do quick and dirty tricks to get what I need, so here it is the plugin in all it’s bash glory.

The plugin is commented, although in Italian, but google can translate the comments.

I wrote this plugins some years ago, it works using SNMP as protocol and with the standard (at those times) OID for BigIP. If they’ve not changed, it should work with no efforts. It’s based on v3 of SNMP protocol and the auth and priv are “hardcoded”, so you may want to change them.

Have fun.

Easy routing workaround for Linux Fortinet SSL client

So you have your Fortinet Linux SSL VPN client, you setup your credential, fire up the connection, it connects, then you do not have access to any of your machines on your private vpn.

Nasty.

You can see sent and received byte numbers flipping on the forticlient window, but you go nowhere.

Errrr!!! Routing problems.

Go either in your 64bit or 32bit client directory and edit

Look for the following line:

and change it to:

That’s it. It’s a simple matching problem.

As you can see in :

It fails to grep the IP address for the ppp0 interface and so, it fails to create a new route towards your private network.

Easy and nasty.
