snmpd -verify if the mibs are loaded.

If you are setting up the snmpd server and have added your own mibs and do not really know if the mibs are loaded or not then simply go to the directory:

/var/lib/net-snmp/mib-indexes

This can save you a lot of time, if you are not getting results with snmpwalk. You can even use snmpwalk as :

snmpwalk -v  -c

Well, these little things can save you a lot of time 🙂

Music players on Linux – the poor mans random song player.

If you have more applications running on your system then your system can handle them then you know what I mean when I say that the Music Players take a lot of CPU. Otherwise harmless, but when you are doing too many things, then lot of times you would feel that probably stopping the Music player might help. But then Linux is all about alternatives. So, there is a command line player called mpg123, which does not use so much CPU. But what about playlist 🙂

unable to browse windows network with samba4

I use Fedora 17 on my work laptop and thus need to connect to windows share sometimes. After I upgraded to Fedora 17 some time, I was unable to browse the windows network. I would get all kind of errors and warnings and tried everything that I knew about Samba to fix the issue. Tried searching through all the forums to figure out what was wrong but nothing helped. And suddenly today I resolved it and guess how:

pigz -parallel gzip

Here is a short description of pigz:

pigz, which stands for parallel implementation of gzip,
is a fully functional replacement for gzip that exploits
multiple processors and multiple cores to the hilt when compressing data.

And for the installation:

sudo yum install pigz

With pigz, if you don’t have many things running on your multi processor machine then you will see a significant improvement when you are gzipping the files.
