Linux Bandwidth Traffic Monitor

I’ve been looking for good tools on displaying bandwidth monitoring on Linux for a while, and finally came across this good Bandwidth Monitoring article on the different tools avilable for Debian/Ubuntu.

Also, found a good capture filter to see the Http Get requests

sudo tshark ‘port 80 and tcp[((tcp[12:1] & 0xf0) >> 2):4] = 0x47455420’

UPDATE: I’ve found the above code to be buggy.

UnMount fs – file system busy & mkfs Inodes

While trying to resize a filesystem, I found that umount failed with busy while fuser and lsof didnt display any files open, found a post the suggest the following

  • fuser -vm /var

To create a ext4 fs with more Inodes (df -i) about double the standard.

  • mkfs -t ext4 -i 8192 /dev/sda6

List by uuid

  • ls -l /dev/disk/by-uuid/

E-Maxx Lowrider

Upgraded the E-Maxx to new Big Bore shocks, and Aluminium knuckles. Didnt quite work out as planned, sits way too low. I’ve got some Losi 4.1 rate light blue 2.5″ springs for the 4 corners (not all 8 shocks), will compare the 2 setups.

Slash VXL 4×4 Short Course Truck

Got a new RC truck a few weeks ago, mainly for the kids to be able to drive when i’m driving my truck. However, I’ve been having more fun with it than they have. Great little truck for the BMX track, good in the gravel, can just throw it around. Super tough too, although i ahve broken the A-arms, but its not been treated gently.
