Cheap iftop

Shows updated status in a terminal window for connections to port '80' in a human-friendly form. Use 'watch -n1' to update every second, and 'watch -d' to highlight changes between updates.

If you wish for status updates on a port other than '80', always remember to put a space afterwards so that ":80" will not match ":8080".

watch snapshots commit in VMware ESX

To monitor .vmdk files during snapshot deletion (commit) on ESX only (ESXi doesn't have the watch command):

1. Navigate to the VM directory containing .vmdk files.

# watch "ls -tough --full-time *.vmdk"

where:

-t sorts by modification time

-o do not list group information (to narrow the output)

-u sorts by access time

-g only here for the purpose to easily remember the created mnemonic word 'tough'

-h prints sizes in human readable format (e.g., 1K 234M 2G)

--full-time sets the time style to full-iso and does not list user information (to narrow the output)

optionally useful parameters to the watch command:

-d highlight changes between updates

-n seconds to wait between updates (default is 2)

-t turn off printing the header

Monitor open connections for httpd including listen, count and sort it per IP

It's not my code, but I found it useful to know how many open connections per request I have on a machine to debug connections without opening another http connection for it.

You can also decide to sort things out differently then the way it appears in here.

create disk copy over the net without temp files

I wanted to create a copy of my whole laptop disk on an lvm disk of the same size.

First I created the logical volume: lvcreate -L120G -nlaptop mylvms

SOURCE: dd if=/dev/sda bs=16065b | netcat ip-target 1234

TARGET: nc -l -p 1234 | dd of=/dev/mapper/mylvms-laptop bs=16065b

to follow its process you issue the following command in a different terminal

STATS: on target in a different terminal: watch -n60 -- kill -USR1 $(pgrep dd)

(see http://www.commandlinefu.com/commands/view/4356/output-stats-from-a-running-dd-command-to-see-its-progress)

output stats from a running dd command to see its progress

if you start a large dd and forgot about statistics, but you still wonder what the progress is this command in an OTHER terminal will show you the way.

NOTE: the watch command by itself will not output anything

NOTE: the kill command will not kill the process
