Multiple Authorized Keys

Thomas Bonham [thomasbonham at bonhamlinux.org]


Mon, 3 Mar 2008 17:33:30 -0700

Anyone know of a way to have multiple ssh authorized_keys files for host key authentication for different users. I am familiar with the usual practice of echoing all of the users keys into authorized_keys file but I am thinking in terms of if I have to revoke keys and disable user access. What I would like to do is have a setup similar to apache in that it can have files included in the conf directory. So this way I have a user name or identifying indicator of whose key is whose so I can revoke access as the necessity arises.

Thank you for all of your help.

Thomas

[spammer@spammer.com] Need to get a quote on a linux email list ASAP -- can you recommend an email vendor?

Ben Okopnik [ben at linuxgazette.net]


Tue, 11 Mar 2008 22:09:31 -0400

Oh, this is rather special - in the highly dubious sense of the word. Spammers are now recognizing the value of Linux... for spamming campaigns. Wow.

Comments, anyone?

Greetings,

We're conducting a time sensitive email marketing campaign and are looking to buy a high quality list and wanted to see if you could provide an email list for this campaign.

-Linux platform and more than 200 servers.

Anywhere in the US and level: IT directors or higher (including CIO, CTO)

If it can be even more granular to include RedHat Enterprise 4 or 5 as well as CentOS 4 or 5, we definitely can use that bit of information. Please call me with any introductions. will your list be opted-in and will we be provided proof for this? We're using Salesforce and VerticalResponse, and need to be able to use VerticalResponse.

Thanks in advance for any help or guidance you can provide.

Any one experienced with Iozone?

Amit Kumar Saha [amitsaha.in at gmail.com]


Mon, 10 Mar 2008 12:24:08 +0530

Hello,

I am currently trying to get some experience using 'Iozone' to obtain some I/O test results on my Linux 2.6 disk partitions. Subsequently, I would like to use my knowledge to do some analysis in a RAID project I am working on.

Do we have anyone here experienced with using the 'Iozone' tool (http://www.iozone.org/) ? It would be nice to know of your experiences.

Thanks, Amit

I have a procedure for dealing with when my users put spaces in their filenames.

find / -name '* *' -exec ls -l {} \;

Taking the third column in the output, you get the username, which you can then pipe to ps -u -o pid | xargs -i kill -9 {}

This gives you the list of users with spaces. Some manipulation with Awk, or Perl, can turn this into a list of usernames prefixed with userdel -r, which can then be piped to /bin/sh.

After you've finished deleting your accounts, you can then hire a hitman to ensure that they never receive accounts on any of your systems again.
