Enable Netfilter/Iptables on ArchLinux

I was surprised that iptables modules are not loaded automatically on ArchLinux. Here’s how you load them. Dump the following lines in any file (for eg. netfilter.conf) under modules-load.d and restart your machine. Alternatively load the modules manually if you want to avoid restarting.

@~ 1028$ cat /etc/modules-load.d/netfilter.conf 
x_tables
ip_tables
iptable_filter
iptable_mangle
nf_conntrack
nf_defrag_ipv4
nf_conntrack_ipv4
nf_nat
iptable_nat

I have been using a MacBook Pro at work for the past 6 months. I’m not a huge fan of either the MacBook or Mac OS X. OS X according to me is highly bloated and a very poor unix platform. Try entering a command line option at the end of a command – For eg. ls * -l.

Having shifted to Arch Linux for the past month or so, I had been missing the two-finger scrolling. The trackpad that comes with my Lenovo Thinkpad recognizes multi-touch gestures. So I decided to look up how to get two finger scrolling to work and it was surprisingly simple. Continue reading

Using Picasa as a Photo Viewer in Arch Linux

I just added a package on AUR which enables using Picasa as a Photo Viewer. Got the inspiration from here.

If you already have yaourt installed, then installing the application is a breeze.


yaourt -S picasa-photo-viewer

Sample installation log is shown in the following screenshot

Ubuntu Tweak is a good utility to change the default photo viewer to Picasa, looking for a ‘PicasaPhotoViewer’ application in the list.
