Making CentOS 5.1 Live on USB Writable
by Mark Rose 03 Mar '08

03 Mar '08

I recently made a Live USB by using the directions in the LiveCD Trac. It works very well, but I was wondering if there is a way the partition - in my case, /dev/sda1, can be made writable. I tried changing the kickstart file to mount everything RW, but it did not work. I know I can always create a second partition on the pendrive, but I would like all filesystems accessible by both CentOS and Windows. Any and all suggestions will be appreciated. Thanks! Mark

HD Failures
by Jimmy Bradley 03 Mar '08

03 Mar '08

I'm just curious if any one else has noticed this. I've bought hard drives from both Walmart and Best Buy. If I can wait, I order them from newegg.com. I'm beginning to think that the staff at both Walmart and Best Buy, somewhere along the supply line must dribble the drives like basket balls. The reason I say that is all the drives I have bought from those two places fail within a few months time. Has anyone else noticed that? Just curious. Jim

Especially when this is a work in progress like dspam and Apache, it would be a really a good idea to wait until I've got the kinks worked out. Let me get my "how I did it" for dspam and Apache on my blog and then we can decide whether it belongs on the wiki. Cheers, Dave -- Politics, n.

Simple question. In the motherboard bios should PnP OS be enabled or disable on motherboard running Centos 4.x? Matt

CentOS, ISDN and Fax ...
by Ralph Angenendt 02 Mar '08

02 Mar '08

Hey guys, is anyone of you using CentOS (4/5) for an ISDN fax gateway? I just had someone over here at the CentOS booth who wanted to know if there's a possibility to integrate the AVM CAPI into CentOS and then use the machine as a fax gateway with 2, 3 or 4 S0 buses. Is that possible?

Odd AVC from tcpdump
by Robert Nichols 02 Mar '08

02 Mar '08

Whenever tcpdump fills a savefile to capacity (-C option) and tries to open a new one, I get the following AVC denial: kernel: audit(1204485464.409:106): avc: denied { search } for pid=2702 comm="tcpdump" name="/" dev=hdb1 ino=2 scontext=system_u:system_r:netutils_t:s0 t context=system_u:object_r:default_t:s0 tclass=dir Any suggestions as the the proper fix to make this work? The target directory for the savefiles has context system_u:object_r:netutils_tmp_t, and I get no complaints about that directory or its files. I have no idea what tcpdump might be searching for in the root directory or, for that matter, why search permission in a default_t directory should be denied. System: CentOS 5.1 selinux-policy-targeted-2.4.6-106.el5_1.3 kernel-2.6.18-53.1.13.el5 tcpdump-3.9.4-11.el5 -rwxr-xr-x root root system_u:object_r:netutils_exec_t /usr/sbin/tcpdump -- Bob Nichols "NOSPAM" is really part of my email address.
