21 Jul 08 Disable ’su’ for one user (cont.)

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

21 Jul 08 Disable ’su’ for one user

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…>

 

 

root

user1

user2

 

 

30 May 08 RHEL3 + SNMPd + Localhost

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

25 Apr 08 Ubuntu 8.04 (64bit) + Skype

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.

25 Apr 08 Ubuntu 8.04 + HP Pavilion DV9000

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

13 Nov 07 RHEL# + USB

When connecting a USB drive to a RHAS3 server I saw this in the ‘dmesg’ output:

hub.c: new USB device 00:1d.7-6, assigned address 3
usb.c: USB device 3 (vend/prod 0x1058/0x900) is not claimed by any active driver.

To fix do:

root@vm:~$ modprobe usb-storage
root@vm:~$ dmesg
[...]
Initializing USB Mass Storage driver…

01 Nov 07 Debian + VNC

My workstation at the office is windows (don’t ask), and I have a mac at the house. I haven’t configured rdesktop for the office and truthfully don’t really want to waste time learning it. So in order to work on my VMs I configured VNC on my Debian server. Its very simple!


mezcal:~# apt-get install vncserver -y
mezcal:~# vncserver -geometry 800x600 -depth 24


The first time I ran VNC I received this error:

could not open default font 'fixed'


I was able fix this by installing xfonts-base

mezcal:~# apt-get install xfonts-base


Now I’m able to VNC in and use X to add/modify VM’s.

To kill use: vncserver -kill :1

If anyone knows of a better way to use VMware on a Mac (ppc) please let me know.
