I have a directory of backups that looks like this:

I want to delete all but the most recent 3 of every file-prefix, so in this case all the zeta-****.tar.asc files except the last three. I have a kind of complicated perl script that accomplishes this, but I'd like do be able to do it with bash.

Slick snippets appreciated!

I'm looking at a tcpdump of my network and seeing floods of mdns packets from my W2k3 AD Server. :

03:28:30.655189 IP mydomainserver.local.mdns > 224.0.0.251.mdns: 0*- [0q] 1/0/0 A 192.168.100.1 (40)

Why is it doing this and how can I stop it?

I'm writing a bash script, parsing options with getopts like this:

    #!/bin/bash

    while getopts ab: ; do
        case $opt in
          a) AOPT=1
             ;;
          b) BOPT=$OPTARG
             ;;
        esac
    done

I'd like to have the "-b" option OPTIONALLY take an argument, but as it is, getopts complains if no argument is passed. How can I accomplish this?

Thanks!

I'm looking for a simple revision control system for server configs. Something like works like git, but preserves Unix file permissions. And is NOT RCS.

Any tips?

Thanks!

What's the difference between IntelPro MT and IntelPro PT server adapter cards? Would one of them be better for iSCSI?

I have a file system backup in a tar archive, created with:

cd / && tar -cpz -f mybackup.tgz usr/local

Doing a

tar tvzf mybackup.tgz 

yields:

-rw-rw-r-- otto/otto      450 2010-04-15 22:08 usr/local/alpha-4.5/pkg/conf/PLATFORM/sparc
drwxr-xr-x otto/otto        0 2009-04-01 08:08 usr/local/alpha-4.5/pkg/ui/
drwxr-xr-x otto/otto        0 2009-04-01 08:08 usr/local/alpha-4.5/pkg/ui/src/
drwxr-xr-x otto/otto        0 2009-04-01 08:08 usr/local/alpha-4.5/pkg/ui/src/thyc/
-rw-r--r-- otto/otto     2416 2001-01-13 16:01 usr/local/alpha-4.5/pkg/ui/src/thyc/vid45
-rw-r--r-- otto/otto      569 2001-01-13 16:01 usr/local/alpha-4.5/pkg/ui/src/thyc/vid46

however, extracting like this:

tar xvpz -f mybackup.tgz 

results in the following permissions:

snip...

-rw-rw-r-- 4 otto otto  450 2010-04-15 22:08 usr/local/alpha-4.5/pkg/conf/PLATFORM/sparc
drwx------ 4 root root  4.0K 2011-03-27 23:20 usr/local/alpha-4.5/pkg/ui/

-rw-r--r-- 4 otto otto  569 2001-01-13 16:01 usr/local/alpha-4.5/pkg/ui/src/thyc/vid46

...snip

Notice the second line. For some reason, the directory is now owned by root and the permissions have changed to 700. Its children, who have the same original permissions as their parent, are created with the correct permissions. This is just an excerpt, this is all over the place in the extracted backup.

What could cause this?

Thanks!

I'm trying to set up a secure git repository server using ssh-keys and git-shell. Since our user database is stored in a central LDAP directory, I can't change users' default shell to git-shell, so I've tried prepending the git-shell command to the public key in the authorized_users file like this:

command="git-shell -c $SSH_ORIGINAL_COMMAND" ssh-dss AAAAB3NzaC1kc3...

However, git-shell won't even allow me to clone the repository:

    dhcp202:git-ws frank$ git clone ssh://gitserver/var/repos/git/myrepo/
    Cloning into myrepo...
    fatal: What do you think I am? A shell?
    fatal: The remote end hung up unexpectedly

Any ideas appreciated...
