I just upgraded to CentOS 5.5 and while talking to a friend of mine we got into talking about updating vs clean install. After my update I had to restore to an image before the update as my mail system was not working, checked all packages contained in the update and zeroed the cause to a sendmail update. Which was disabling my current MTA “postfix”. I fixed that and another issue with my open office and I was ready to go. While my friend prefers to just do a clean install.
To me it just comes down to preference, if you have a heavily customized system it’s time saving to just do an upgrade, but if you are running a generic system with few modifications a clean install might be the best way for you.
Do a back up a recoverable system backup or a backup for all important docs you have on system before you proceed with the commands below
yum clean all
yum update glibc\*
yum update yum\* rpm\* python\*
yum clean all

I had installed ipupdate while trying out dnsexit.com and loved its simplicity, dnsexit.com provides a great service but in the end I chose to stick with my current registrar lqconsulting who is a major supporter of Linux users, they also run linuxquestions.org of which am a member. I had tried to configure ddclient to work with my registrar but I did not have enough info about my registrar’s requirements of the client to work with their site. So in the mean time I have edited ipupdate to send me an email everytime my ip address changes while still doing evrything else it does. I prefer it this way over updating my registrar, since I do a lot of remoting in and it takes a few minutes before a new IP is updated to nameservers “around 20min”, but if I already have my new IP in my mail when it changes I don’t have to wait until nameservers update my site IP for me to be able to remote in. I have provided the edited file below for anyone who wants to use it also the tar,rpm and deb files that install it.

You can replace the installations ipupdate.pl with mine for v1.6-2 or just copy over my additions to them whichever works for you.
The one good thing about Linux is the range of distributions available. Every few months I will load a new Distribution on my flash drive or make a Live cd and try it out. I am currently trying out Linux Mint and I like it, I would definitely recommend it for new users it comes loaded with most apps that you need day to day. It’s eye candy is one of the best I have checked out so far, I even loaded it onto one of my old boxes that am planning on donating.
Do you have a linux box or you have booted of a live cd and you want to mount a samba share here is the command(s) for it.
#smbmount //ipaddress/share /mnt/moountfolder -o username=username,password=password
#mount -t cifs -o username=username,password=password //ipaddress/share /mnt/mountfolder
Any of the two methods above should work. You can use the name of machine instead of ip address if you want, and no space between username and password else you will get an error.
Am assuming you already have MySQL installed, download the MySQL Connector-J from their website.
Unzip/Untar the file and copy mysql-connector-java-version-bin.jar to java jre/lib/ext. Doing this will allow the java interpreter to find the driver.
