uuencode and uudecode are missing from CentOS 5

What a surpriese. I need those sometimes when mailing things from cron so after a quick search around I found the (intuitive named) package that contains those utilities is sharutils.

Disabling external access to the DD-WRT WebGui

silviuLeave a comment

So, playing with DynDNS and DD-WRT I worryingly observed that even if I set

Administration->Management->Remote Access->Web GUI Management

to off I can still access my router’s management WebGui via the external address. That seemed wrong, I was about to set firewall rules to block this unitl I tried from my phone using 3G. The WebGui was inaccessible.

The WAN WebGui still works from the INSIDE! But don’t worry it won’t work from outside your network.

Nagios Grapher fun

silviuLeave a comment

I was struggling with Nagios Grapher (or was it nagiosgraph – I tested both)  in Slackware 13.1 After installing all dependencies it would still refuse to work. I tracked the problem pretty easy to be related to Perl not being able to load the librrd.so.4 library.

That was funny as I was sure that I did configure, make and make install the latest version. Well, by default, on slackware at least rrdtool installs in /opt !

I added /opt/rrdtool-x.x/lib in /etc/ld.so.conf  (check to see what is the exact path in your case) and rerun ldconfig. Sure enough everything worked fine.

This is the error log I received:
