Long time no update
November 23rd, 2008
Damn, its been some time since I’ve updated the old blog. I’ve been to London and New York in that time and haven’t had one thing to write about. Well I’ve actually had a lot to write about just been kind of lazy.
I’ll update the blog some time soon.

Disable ’su’ for one user (cont.)
July 21st, 2008
There is another way to do this, its a little sexier in my opinion 
It involves using Linux ACL’s, can you feel the sexy?
Here is all you have todo:
Enable ACL’s on the partition:
# vi /etc/fstab
/dev/sda3 / ext3 defaults,acl 1 1
Remount the partition:
# mount -o remount /
Disable ’su’ for the selected user:
# setfacl -m u:user1:000 /bin/su
Check your work:
# getfacl /bin/su
# file: bin/su
# owner: root
# group: root
user::rwx
user:user1:---
group::r-x
mask::r-x
other::r-x
Disable ’su’ for one user
July 21st, 2008
Ever need to disable ’su’ for a single user? Ever want to do this and skip the “wheel” group? Here is a good how-to:
We need to first add the group we will be using, since we will not use ‘wheel’
# groupadd rootmembers
We will now need to add users to the group, note that this will make ‘rootmembers’ the secondary group for the user
# usermod -G rootmembers user1
# usermod -G rootmembers user2
Pam Config
Since /etc/pam.d/su is configured to only allow access for all or only ‘wheel’ we need to tell it to look at a different file:
<.../etc/pam.d/su...>
auth sufficient /lib/security/$ISA/pam_stack.so service=su-root-members
auth required /lib/security/$ISA/pam_deny.so
<...end of file...>
The first line tells PAM to look for the additional file, the second line tells PAM to deny the request if the requirements of the additional file are not met.
Create a file in /etc/pam.d called “su-root-members” and add these lines:
<.../etc/pam.d/su-root-members...>
auth required /lib/security/pam_wheel.so use_uid group=rootmembers
auth required /lib/security/pam_listfile.so item=user /
sense=allow onerr=fail file=/etc/security/su-rootmembers-access
<…end of file…>
The ’su-root-members’ puts in place two road blocks, 1) the user must be in the ‘rootmembers’ group, and 2) the user must be in the
/etc/security/su-rootmembers-access file.
/etc/security/su-rootmembers-access file.
Create the /etc/security/su-rootmembers-access and add your users:
root
user1
user2
*IMPORTANT*
On a RHEL3 server I missed the “root” user in the /etc/security/su-rootmembers-access and “su” failed for ALL users. However on a CentOS5 server I just had my username listed and everything worked just fine. The only major difference between the two were the OS version and the version of pam installed.
RHEL3 + SNMPd + Localhost
May 30th, 2008
this past week I was asked to make SNMPd listen to the loopback IP. I never had to do this and it turned out to be a pain in the ass. When I figured out the answer I kicked myself in the face. To help save other peoples time here is how to do it:
Change /etc/init.d/snmpd from:
OPTIONS=”-s -l /dev/null -P /var/run/snmpd -a”
TO:
OPTIONS=”-s -l /dev/null -P /var/run/snmpd -a 127.0.0.1″
Hope this helps
Ubuntu 8.04 (64bit) + Skype
April 25th, 2008
sudo apt-get install ia32-libs lib32asound2; wget -O skype-install.deb http://www.skype.com/go/getskype-linux-ubuntu; sudo dpkg -i –force-all skype-install.deb;
Vidio should work with it, however haven’t tested yet.
Ubuntu 8.04 + HP Pavilion DV9000
April 25th, 2008
I’m not much of Ubuntu user, I tend to lean toward Fedora. Just for shits and grins I installed 8.04 this morning on my HP Pavilion DV 9000 laptop. I’m SOLD! I’m staying on Ubuntu. Right out of the box a number of items just work.
Working:
Headphone jack - Don’t have to recompile ALSA any more (thank god!!!)
Dual monitor - On Ubuntu 7.10 dual monitor was a pain in the ASS! on 8.04 I just uploaded my Fedora xort.conf and it worked right the first time.
Not working:
Wireless: Haven’t had time to mess with it
Not avail:
I can’t find my display settings, I would really like to make changes with out having to manually edit my xorg.conf. Oh well, its good enough for me.
NOTE: I’m running Ubuntu 8.04 amd_64
——
Update 10:50 CST - Firefox 3 Beta sucks, the “manage bookmarks” is a real pain in the ass to work with and the incorrect certificate window is stupid. I removed Firefox3 and put Firefox2 on.
<rant>
I don’t understand how you release an OS with a beta browser? Who ever made that decision is a tool and should not have that authority.
Bad decission

RHEL# + USB
November 13th, 2007
When connecting a USB drive to a RHAS3 server I saw this in the ‘dmesg’ output:

To fix do:
