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.

Hi I see some distro's, like Ubuntu has a nice short chime / sound when a machine is fully booted.

question on how yum updates cache
by Rogelio 01 Mar '08

01 Mar '08

I'm trying to make sense of CentOS's package management based on what (little) I know about Debian's. When I do a "yum install program" and it takes forever, is it updating local cache to install the most up-to-date version of that program? When I do it in Debian, it seems to install whatever version is in the "apt-cache" (unless I "apt-get update").
