Just a quick update to an old post I made: Disabling IPV6 to tweak network connectivity. The tweak mentioned on the post will only work for kernel versions prior to 2.6.28-4 as discussed on the following bug report: IPV6 causes slow internet access. Sorry for those who have tried to apply this tweak and failed. If you are using kernels prior to 2.6.28-4, this will still work.

March 17th, 2009Ubuntu Linux: Tweak your network connectivity and/or performance by disabling IPV6
September 1st, 2008Update: 17 March 2009: A quick note – this will only work for kernels preceeding 2.6.28-4.
While browsing for a solution for Firefox’s slow connection “bug”, I found a more “global” solution in Ubuntu. In short, the global solution is to blacklist IPV6.
You can do this simply by adding the following to /etc/modprobe.d/blacklist:
blacklist ipv6

Evolution Mail Client Mixed messages up!!!
June 27th, 2008I’m inches away from shoving my fist through my laptop screen! I don’t know how something like this could happen, but Evolution, the Mail Client I’ve switched to, has somehow mixed my email messages up. This is a real pain in the neck because while there was a solution for fixing it up by moving the files into a new folder so that they will be in sync again, it doesn’t fix the emails that I have received in the past few days – and these were the most important ones!
With this, I’ve decided to ditch Evolution. Such a pity, I liked how it worked and all that, but this is the second time this has happened. Evolution is out, good old faithful email workhorse Thunderbird is back in action.

Instant or Passwordless SSH-ing in Linux
March 3rd, 2008Well, to be “correct” the title of this should have been “how to add your key to the list of authorized public keys on a remote or local linux machine”, but being a newbie like myself, I would not have known to search for it. If I wanted to find out about logging in automatically to a remote machine using a generated public key, I myself would have used “Passwordless SSH” – so there you go.
To get started, I’ll assume that you have OpenSSH set up (it’s setup by default… well usually) and that your remote machine has OpenSSH-server set up.
If not, then do the following on the remote machine:
$ sudo aptitude install openssh-server
