How to allow tracing of VLAN Tags in wireshark

Submitted by bhal
on October 7, 2010 - 8:02am

Problem:
--------

Wireshark captured the incoming Ethernet Frames without any VLAN tags because the driver stripped VLAN tags from the received frames. How can I see VLAN tags in incoming frames?

Solution:
---------

Patch the ixgbe driver:

File: ixgbe_main.c

Function: static int __devinit ixgbe_probe(struct pci_dev *pdev,
const struct pci_device_id *ent)

Once upon a time my friend pulsar Sheshka asked me to extend `vtun` to support traffic from user space (say, IRC clients). At that time he wanted to try to have free Internet (e.g. IRC was for free). And it was done so, right before I went to .CZ, where Internet connection was awfully fast.

There I did some work about IRC bots, connecting two via tunnel, as shown below:

ubuntu is useless for servers

Going to describe this entry a bit later, but in short "ubuntu server edition can't be plain installed on a server via serial console connection, but with custom made iso/cdrom, which is not always an option".

don't discuss this entry here, better go to bug-report URL and put your thoughts there.

Recently installed a new backup server with Bacula and connected to our SAN based on Brocade switches and HDS (DF700XS unit type, microprogram rev. 0781/A-X). We've never tested this HDS unit, but I was interested, so pasting results here.

I went to see The Queers last night in concert. It was a decent show, and TA80 was there from Tucson (a great bunch, BTW), as well as The Leftovers (from Maine; also a cool bunch).

how to use serial for both pppd and getty

Submitted by zixenus
on July 22, 2009 - 7:38am

Hi Everybody, I am using our only serial port(/dev/ttyS0) for pppd. We are also getting console output through serial. So, to get things going I blocked getty in inittab. I am currently connecting my box via ssh and then i can run pppd, chat script etc.Can I have a setup so that I can give exlusive access of serial to pppd when it runs and when it exits it will unblock it?
