Python 2.4 on CentOS4?
by Eric B. 11 Mar '08

11 Mar '08

Hi, Has anyone managed to find a Python 2.4 rpm binary that can be installed on CentOS4? I'm running CentOS4.6 and an application that I want to use required python 2.4 or greater. All the CentOS/RHEL4 python rpms that I find are all for python 2.3. I can't seem to find anything that works with CentOS4 libs. Thanks! Eric

Linux Sound Architecture (Updated)
by Ross S. W. Walker 11 Mar '08

11 Mar '08

I forgot the most important part in the original, the kernel! (I hope the ASCII art doesn't get mangled) I have been working a while trying to get a big picture of how Linux handles sound processing and after much work I have put together this little representation of what I have learned. Please send me any additional comments or components that I may have missed. I hope it helps somebody though who may be struggling in getting sound to work and just needs some idea of how all the parts fit together. There really needs to be some concise, up-to-date Wiki on Linux sound processing and how the different applications work and work together (or not).

Hi, Anyone have this type of monitor hooked up and running? Any issues that I should be aware of? I've hooked this monitor up to my system. I have a Nvidia card FX550 with 256MB Ram. I haven't done anything special with it, still learning the in's and out's of the monitor. So far so good. Guess time will tell. -- Regards Robert Smile... it increases your face value!

Automatically send CTRL-D
by Mário Gamito 11 Mar '08

11 Mar '08

Hi, Sorry for the little bit off-topic. I have a script that has to performe a hash over a password. Problem is that sha512sum expects CTRL-D to be pressed to return to the command prompt. I've searched all over Google, but either I didn't do the right search or there is nothing relevant about this. Bottom line is that I need this command to print the password hash and returns to the shell automatically: $ sha512sum | xargs echo "password" | cut -f2 -d' ' Any help would be appreciated. Warm Regards, Mário Gamito

DNS Caching for a satellite link
by Benjamin Weiss 11 Mar '08

11 Mar '08

I'm on a satellite link, and I've got a caching DNS server set up. Several popular sites have very short DNS cache times set in their SOA records, and I'm trying to over-ride them so that our link isn't swamped with DNS queries. Anybody know how to force the DNS cache to hang onto the info longer than the SOA TTL? Yes, I know the arguments against doing this, but in this particular instance it makes sense. I'm using CentOS 5 and bind 9.9.3. Thanks! Also, do caching web proxies like Squid still speed up the web experience over a slow link what with all of the dynamic content on the web these days?
