Had to do a second install on the remote computer (I probably did something wrong the first time) but everything that I needed to work, does work. I even have sound to my local computer from the remote computer via a windows application running with wine on the remote computer. Thanks for your recommendation.

CentOS 4 update backlog
by Vandaman 13 Jan '09

13 Jan '09

There are security updates upstream for CentOS (4 and 5) and it looks like the CentOS 5 ones have been rebuilt and rolled out. How come the CentOS 4 branch lags behind, or are the CentOS 5 devs different from the CentOS 4 devs? If more volunteers are needed I'm sure assistance could be offered by the CentOS community. Regards, Vandaman.

What is there available for Centos? Now that Audacity is no longer available to us... I do have Audacity on an XP system, so I do have the option to shuffle files between systems....

After BIND update owner changed and restart failed
by Robert Moskowitz 12 Jan '09

12 Jan '09

I just applied the BIND updates. Then I fixed the one file that had a second include of named.ca (remembered that from last time) and did a 'service named restart', and it failed. In messages I found: Jan 10 21:31:17 z9m9z named[31001]: loading configuration from '/etc/named.conf' Jan 10 21:31:17 z9m9z named[31001]: /etc/named.conf:11: open: /etc/named.acl: permission denied Jan 10 21:31:17 z9m9z named[31001]: loading configuration: permission denied Jan 10 21:31:17 z9m9z named[31001]: exiting (due to fatal error) Oh, I remember this from the last update... So off to /var/named/chroot/etc and do a 'chown named:named *' then named started. This apparent changing of file ownership in installing a new set of bind updates so that named cannot access the files seems like something is broken somewhere.

yum update fails: CentOS 5.2
by Mike -- EMAIL IGNORED 12 Jan '09

12 Jan '09

It gets as far as telling me: Total download size: 207 M It doesn't ask if its ok. But if I type y<enter> it reports: Is this ok [y/N]: Downloading Packages: Then it does nothing. I can't kill it with CRTL-C, but I killed the yum process with kill -9 from another window. I retried it several times; same result. Thanks for your help. Mike.

anyone using an ATI card and fglrx with 5.2?
by Dave Stevens 12 Jan '09

12 Jan '09

And does it work ok? any special use cases or installation issues? I'm thinking of a 64 bit installation with an RV530 chipset. Dave -- Canada must refuse to be entangled in any more wars fought to make the world safe for capitalism. -- The Regina Manifesto, 1933

hostapd or other AP software for Centos
by Robert Moskowitz 12 Jan '09

12 Jan '09

Is there a recent rpm available for hostapd? I found 0.6.0 over at atrpms.net via rpmfind. Actually a more recent ver than available for FC8,9, or 10! But http://hostap.epitest.fi/hostapd/ shows the current version is 0.6.7. And does anyone have this running on Centos? Is there a 'better' AP software? I have the Atheros card in my notebook for this....
