New improvements in site.

2012-11-16 1 min read Uncategorized

Have spent some time today to speed up the blog today and made some improvements.

Today I finally managed to get some time to update my site and change theme. I also made some changes that should decrease the page loading time. Have updated the “Sitemap” page and also the contact me page. There are couple of other changes that should make your experience a lot more better.

XDMCP is protocol that allows remote connections and provides you with a working Display Manager like KDE, GNome, et al. Its a remote connection protocol that is mostly enabled on Solaris and disabled on most Linux boxes. If you need to have a remote session where you need the X Display to open some GUI applications then you can have a connection with the remote server with XDMCP.

There are couple of ways to make life easier with CVS diff. But here is one that is really good.
First if you haven’t, install meld:

sudo yum install meld

meld is basically a diff viewer and pretty good at it 😉

phpmyadmin access problem and change server from URL

2012-09-30 1 min read Database Fedora

I was having issues with one of the phpmyadmin setups. The first server defined in the config file was not accessible and the theme that I was using was not allowing me to change the server from the first page. This resulted in a state where I was not able to access phpmyadmin in any way. I could not connect to any of the servers. And thus had to hack my way in to phpmyadmin to find out how to connect to other servers from URL. And here is my finding:

Shortcut to run current command with sudo in bash

2012-09-20 1 min read Fedora Linux

For me, I mostly forget to add “sudo” to the command until the time I am actually supposed to run it. Also sometimes, on some systems, bash completion does not work as expected with “sudo”. With these in mind, I wanted something such that when I have completed the command, I could insert sudo in the begining of the command without much ado. So, finally this is what I came up with in my “~/.inputrc” file. Note: If you don’t have this file, then simply create this file.

Ubuntu – Really force remove a package.

2012-09-17 1 min read Linux

I was trying to remove a package on one of the Ubuntu installations the other day and was not able to do so. I tried google and tried all the options mentioned in various forums like “-f”, purge, reinstall and few others but nothing helped. I kept getting some errors about some files being already deleted. I also tried “set -e” in the prompt but the only result I got was terminal also getting killed.

snmpd -verify if the mibs are loaded.

2012-09-10 1 min read Fedora Linux

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 🙂
