wireless card for CentOS
Hi, I'll need to buy a new wireless card. I need a recommendation for PCMCIA wireless card that simply works with CentOS out of the box. By "works out of the box", I mean that it doesn't need ndis wrapper (or whatever it is called), kernel hacks, or whatever. Thanks

This firewall rule will self-destruct
Ok, I have a challenge - get two services working over a single port. (!) Sometimes it's a web service, sometimes it's a VNC service. Here's what I had in mind: 1) Server is normally a webserver listening on port 80, and normally has the following rules active: # iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT # iptables -t nat -A POSTROUTING -j MASQUERADE 2)

How should I create a repo on Centos 2.1?
I tracked down a createrepo rpm "for RHL 7.x, AS 2.1" etc (hosted by Dag), but it's uninstallable. Eventually I managed to create an rpm from the source (actually, that's fairly easy when onw knows to say "python2"), but python-urlgrabber has completely defeated me. According to Dag, the problem is that "upstream" doesn't see the need to support

setting up incoming PPP on centos 4.4
hi gang! I'm interested in setting up incoming PPP on a system at work that has a fresh (not upgrade) Centos 4.4 on it. All the documentation I've found for that shows using mgetty to do it, and seems pretty straightforward. However, that machine doesn't have a binary named mgetty anywhere. It does have a mgetty-sendfax RPM installed, but it does not provide a binary named mgetty.

openssl package possibly different in CentOS and RHEL
I've just had a problem on one of my x86_64 boxes with openssl package. I have an 32-bit only application that requires openssl libraries. When I attempted to install openssl.i686 (in addition to already present openssl.x86_64), it failed. The rpm complained about conflicting files (they were all manpages), and I needed to use --force option to install the thing. The good folks

mozilla and seamonkey not the same
I have searched the bugzilla and seamonkey has bugs when using "-remote openurl(www.google.com)" it always opens a new window. Mozilla did not have this problem. How can I continue to use the old mozilla? Both for system updates and for new 4.4 installs. I need the -remote functionality to not open new windows. Thanks, Jerry

yum vs up2date
Which is better? Why? I know yum is the official update mechanism here and in Fedora Core, but that doesn't make yum better than up2date any more than Windows NT was better than OS/2. Let's try to keep the discussion objective:-) I'm asking, hoping for some insights into why RH might (apparently) be moving to yum in preference to up2date (yum is now used within Anaconda). Other

NPTL problem on Centos 4.4
Not sure where to ask this, I've been googling and not finding much that is helpful. At work I've got a multi-threaded program targeted at Linux. It compiles on RHEL 2.1 and 3, and is targeted at 2.1, 3, and 4. UP until today, the binary built on 3 has worked fine on 4. But on RHEL4 update 4 it dies a horrible death in pthread_create. I have reproduced the problem on Centos 4.4, where I

postfix pb with mass emails
Hi I'm hosting a forum (phpbb) with more than 3500 users with centos 4.3. The forum admins would like to send an email to its (3500) users. I configured phpbb to use smtp (postfix-2.1.5-4.2.RHEL4.mysql.centos4) to send the email. I raised the max destination limit from 1000 to 5000, and made a test. Here the disaster began: Majority of the users received from 20 to 50 emails. Looking at the
