Site originally by David Winterbottom (user root).

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

» The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
» If you wish to use your user account, you will probably need to reset your password.

Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

ssh -o "ProxyCommand ssh [email protected]_host -W %h:%p" [email protected]_host

User: renich

Functions: ssh

Tags: ssh

Up

SSH connection through host in the middle; with key redirection

This command uses the reachable_host as a proxy; redirecting your request to the unreachable_host.

The main advantage is that you need only one ssh key. You copy the public part to both servers and you can access the unreachable_host without a problem.

Also, you can put this on ~/.ssh/config to access the unreachable_host directly:

# config

unreachable_host

ProxyCommand ssh [email protected]_host -W %h:%p

and, then, just ssh [email protected]_host.

Look at logs startring at EOF

In cases when the user is following a log file that rotates then it is advisable to use the -F option as it keeps following the log even when it is recreated, renamed, or removed as part of log rotation.

To interrupt tail while it is monitoring, break-in with Ctrl+C.

Partition a sequence of disk drives for LVM with fdisk

So, I'm using a CentOS VM in VirtualBox, and created four new disks in the SCSI controller.

The VM created the folders:

/dev/sda

/dev/sdb

/dev/sdc

/dev/sdd

Using a 'for loop' all disks are partitioned for LVM.

Show drive names next to their full serial number (and disk info)

Scrap everything and use `gawk` to do all the magic, since it's like the future or something.

gawk 'match($11, /[a-z]{3}$/) && match($9, /^ata-/) { gsub("../", ""); print $11,"\t",$9 }'

Yank out only ata- lines that have a drive letter (ignore lines with partitions). Then strip ../../ and print the output.

Yay awk. Be sure to see the alternatives as my initial command is listed there. This one is a revision of the original.
