centos with qemu and kqemu
by Jerry Geis 10 Aug '06

10 Aug '06

Any one using qemu with centos and bridged network mode? I am running qemu as: qemu-system-x86_64 -hda centos4.i386.img -boot c -net nic -net tap I am still getting a 10.X.X.X address instead of a DHCP address on my local network. I have the /etc/qemu-ifup script as: #!/bin/sh sudo /sbin/ifconfig $1 0.0.0.0 promisc up sudo /usr/sbin/brctl addif br0 $1 sleep 2 which does run.... I have kqemu running and it is pretty zippy. I just cant get bridged network to work. I am running centos 4.3 on x86_64 (amd 4800+) and trying to emulate and centos4 i386 image. The image works its just not on my network. Jerry

As long as you are extremely careful with the access password, you shouldn't have a problem. I will take this risk for the advantage of being able to easily use highly secure passwords. For example, my online banking password is a sequence of random characters. I don't have to remember it or type it. If I didn't have a tool like this, I would have to either write it down somewhere or use a less-secure password that I could remember. > > Oh...and don't forget backup the password database! :) > > I'm finalizing my LVM-based snapshots with aging of deleted files right > now, so I will be covered.

I figure if he is willing to use it, it's worth a look. http://schneier.com/ (note that the Password Safe information on that page refers to an older version that used Blowfish rather than Twofish) -- Bowie

Wifi wpa_supplicant with atheros successes or failures?
by Max H. 10 Aug '06

10 Aug '06

I remember being a small part of and following this thread a few months ago. <http://lists.centos.org/pipermail/centos/2006-May/065091.html> I've been attempting a go at getting wpa_supplicant running on CentOS 4.3 and haven't had much luck. I'm assuming my failure is my lack of knowledge on the subject, but anyways. First, my normal setup is as follows: IBM Thinkpad R40 Ethernet controller: Atheros Communications, Inc. AR5211 802.11ab NIC (rev 01) Works great and has been working great for over a year now off the madwifi drivers at <http://atrpms.net/dist/el4/madwifi/>. I've done a bit of Googling the past few days as well. One link I follow it mentions about CentOS/RHEL not supporting wpa_supplicant in the current kernel, and that you'd have to recompile your kernel. Other threads I've read of successes, but usually not much detail is provided and it's done so through compiling the drivers and what not. My question is: Has anyone had success off the RPMs on atrpms? I've attempted a shot at it with these: <http://atrpms.net/dist/el4/wpa_supplicant/> and haven't had much luck. It installs after I get a few dependencies and I can configure the .conf file, but after that it just gets really upset about doing anything. Perhaps I can't get it working due to confusion of the packages that I need or don't need. Currently, I'm running the kernel module packages from the madwifi section at atrpms. Any thoughts, help, or comments from the peanut gallery are greatly appreciated. :) Thanks! Max

Least painful MySQL 4.1 -> 5 upgrade on CentOS 4.1
by Morten 10 Aug '06

10 Aug '06

Hi. I've happily been running MySQL 4.1 on my CentOS 4.1 x86_64 server. But I need to upgrade to MySQL 5. Any recommendations on how to accomplish this without too much pain? I guess I'll need to get RPMs from the MySQL website. Br, Morten

The solution to that is a secure password manager. http://passwordsafe.sourceforge.net/ You just have to remember the one password and the program will track all of the rest for you. This way you can use gibberish passwords for important sites such as online banking and you don't have to remember them or write them down anywhere. The password database is encrypted using Twofish and SHA-256. The only real downside is that if you don't have access to the password manager, you don't have access to anything else either. Oh...and don't forget backup the password database! :) -- Bowie
