cryptoloop enabled losetup package
by Alexander Georgiev 31 Jan '05

31 Jan '05

Hi, I have a legacy AES excrypted file system with a 256 key size. RHEL kernel is cryptoloop enabled but the losetup package is not. It needs additional patch. Does anybody have a patched losetup rpm I could use? Thank you! A. Georgiev

x86_64 timer resolution in ping results
by Simon Garner 31 Jan '05

31 Jan '05

Hi, There seems to be a problem with the timer resolution on x86_64. This is clear in ping results - I don't know if it's just a ping problem or if it manifests elsewhere as well. It does also affect mtr and traceroute times. I guess it's more a kernel issue than a CentOS problem, but is anyone else seeing the same? Ping results have a resolution of 10ms - so a ping <10ms shows as 0.000ms... --- On an Opteron machine running CentOS-3.4 --- # uname -a Linux omega.xxx 2.4.21-27.0.2.ELsmp #1 SMP Wed Jan 19 11:28:26 CST 2005 x86_64 x86_64 x86_64 GNU/Linux # ping 192.168.1.200 PING 192.168.1.200 (192.168.1.200) 56(84) bytes of data. 64 bytes from 192.168.1.200: icmp_seq=0 ttl=64 time=0.000 ms 64 bytes from 192.168.1.200: icmp_seq=1 ttl=64 time=0.000 ms 64 bytes from 192.168.1.200: icmp_seq=2 ttl=64 time=0.000 ms 64 bytes from 192.168.1.200: icmp_seq=3 ttl=64 time=0.000 ms 64 bytes from 192.168.1.200: icmp_seq=4 ttl=64 time=0.000 ms --- 192.168.1.200 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4000ms rtt min/avg/max/mdev = 0.000/0.000/0.000/0.000 ms, pipe 2 # ping google.com PING google.com (216.239.39.99) 56(84) bytes of data. 64 bytes from 216.239.39.99: icmp_seq=0 ttl=240 time=230 ms 64 bytes from 216.239.39.99: icmp_seq=1 ttl=240 time=220 ms 64 bytes from 216.239.39.99: icmp_seq=2 ttl=240 time=220 ms 64 bytes from 216.239.39.99: icmp_seq=3 ttl=240 time=230 ms 64 bytes from 216.239.39.99: icmp_seq=4 ttl=240 time=230 ms 64 bytes from 216.239.39.99: icmp_seq=5 ttl=240 time=220 ms --- google.com ping statistics --- 6 packets transmitted, 6 received, 0% packet loss, time 5050ms rtt min/avg/max/mdev = 220.006/225.006/230.006/5.000 ms, pipe 2 ---- Expected result: On an i686 machine running CentOS-3.3 ---- # ping 192.168.1.202 PING 192.168.1.202 (192.168.1.202) 56(84) bytes of data. 64 bytes from 192.168.1.202: icmp_seq=0 ttl=64 time=0.094 ms 64 bytes from 192.168.1.202: icmp_seq=1 ttl=64 time=0.059 ms 64 bytes from 192.168.1.202: icmp_seq=2 ttl=64 time=0.070 ms 64 bytes from 192.168.1.202: icmp_seq=3 ttl=64 time=0.057 ms 64 bytes from 192.168.1.202: icmp_seq=4 ttl=64 time=0.068 ms --- 192.168.1.202 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4016ms rtt min/avg/max/mdev = 0.057/0.069/0.094/0.016 ms, pipe 2 # ping google.com PING google.com (216.239.39.99) 56(84) bytes of data. 64 bytes from 216.239.39.99: icmp_seq=0 ttl=240 time=201 ms 64 bytes from 216.239.39.99: icmp_seq=1 ttl=240 time=203 ms 64 bytes from 216.239.39.99: icmp_seq=2 ttl=240 time=201 ms 64 bytes from 216.239.39.99: icmp_seq=3 ttl=240 time=202 ms 64 bytes from 216.239.39.99: icmp_seq=4 ttl=240 time=201 ms 64 bytes from 216.239.39.99: icmp_seq=5 ttl=240 time=201 ms --- google.com ping statistics --- 6 packets transmitted, 6 received, 0% packet loss, time 5049ms rtt min/avg/max/mdev = 201.044/201.939/203.012/0.926 ms, pipe 2 Kind regards, -Simon

upgrade RH9?
by Edward J. Weinberg 31 Jan '05

31 Jan '05

Can you upgrade RH9 to Centos, or do you have to do a complete install? Is there an iso with a .ks file on it to do a remote install?

Whitebox to CentOS upgrade
by first last 30 Jan '05

30 Jan '05

Hi everyone, I have a home computer that I use to develop on, which it is running Whitebox 3.0. I have copied all the required CentOS 3.4 RPMs to /RPM, created a new yum repository and then updated, but when I try to upgrade, it fails on a "recursive dependency on glibc". Is there any way I can force that dependency? Would it be easier to upgrade to 4.0 using Anaconda? Thanks for all the work Gabriel ___________________________________________________________ ALL-NEW Yahoo! Messenger - all new features - even more fun! http://uk.messenger.yahoo.com

Apcupsd UPS monitoring
by Nigel Kendrick 28 Jan '05

28 Jan '05

Having some fun with the APC monitoring daemon (apcupsd) - I've installed the Whitebox rpm and it runs OK but I cannot communicate with the UPS on ttyS0 or ttyS1. I'm using a supported cable (according to the utility's Web site). I've followed the troubleshooting tips on the app's Web site with no luck - the only bit that I can't resolve is it recommends disabling logins on ttySn - how's this done as I can't find any notes on the site or via a google search. Does anyone have any experience of this utility - and any tips? Thanks Nigel Kendrick

OT: Which programming language should I use?
by Benjamin J. Weiss 28 Jan '05

28 Jan '05

Sorry for the OT post, just looking for a pointer from somebody who's been there and done that. I'm looking to write a program that will allow for managing documents that have been encrypted with AES. I want the program to be as cross-platform as possible, so at the least it needs to run in Win2K/WinXP and in linux X-windows (X.org). Now, I used to write in Java a few years ago, so I guess that's an option. My concerns are that back then Java was slow, and I don't know if there's an easy-to-use cross-platform crypto library for Java. I've seen at least one program that was written in python and Tkinter on the web that offers the source for running in linux, and they offer a .exe download. (http://www.axware.nl) I don't know how they do it, but I saw a claim on the web that python/Tkinter was a great cross-platform combo. The idea is that the user will type in a passphrase and the program will grab the file and either display it (if simple, like text) or launch another program (like pdf). I'll also need to figure out how to tell the program not to swap the memory to disk Any ideas? Thanks! Ben

Benjamin, Although Andrew is totally biased, Python does run well on Linux, Windows and the Mac. Python is hot! http://www.strombergers.com/python/perl_ha_ha_ha.html Rick
