Monitor power save question
by David G. Miller 03 Feb '08

03 Feb '08

I decided to try the x86_64 version of CentOS 5 on my new desktop since it has an Athlon 64 X2 CPU. The one really perplexing oddity is that the monitor no longer goes to power save mode (standby) if the system is idle long enough (e.g., overnight). The "power management" option is set to put the display to sleep after thirty minutes. The display gets blanked but it never goes to standby. The weird thing is that the display behaved as expected when I still had the 32 bit version of CentOS installed so the hardware supports powering down the monitor. I don't see anything incriminating in dmesg, /var/log/messages or /var/log/Xorg.0.log. I'll switch the system to boot to runlevel 3 so I can see if X is spewing something to the first alternate console that isn't getting written to the log file. Anyone have other any suggestions as to diagnosing of fixing the problem? Thanks, Dave -- Politics, n. Strife of interests masquerading as a contest of principles. -- Ambrose Bierce

Networking issue (after latest 5.1 update?)
by Bart Schaefer 03 Feb '08

03 Feb '08

I'm not *entirely* sure but this began happening at about the time I installed the latest kernel updates for CentOS 5.1 (kernel-2.6.18-53.1.6.el5.i686.rpm from January 24). Shortly before that I changed the encryption on my wireless router and switched from ndiswrapper back to the standard bcm43xx driver, but I'm pretty sure the network was OK before that update for the simple reason that I was able to download the update itself. In any case, for the past week or so wireless network connectivity from my CentOS 5 laptop has been terrible. The wireless router is set up as my DNS server, and connectivity is as expected for wired-connected computers and wirelessly from my Mac, from the game consoles, from my work laptop (currently running ubuntu), and from the CentOS laptop when re-booted into Windows XP. So the problem is restricted to CentOS 5. It takes minutes to do DNS lookups, and to establish a connection in the first place takes so long that "stateless" stuff like web surfing ranges from impossible (timeout) to merely unbearable. The automatic software updater hasn't succeeded in connecting ("Details: None") since the 24th. However, SSH connections seem to work OK (if perhaps a little bursty) once I manage to get connected (often by ssh'ng to the destination by IP address rather than by name). I can ping computers on the wired LAN on the other side of the router: PING 192.168.0.100 (192.168.0.100) 56(84) bytes of data. 64 bytes from 192.168.0.100: icmp_seq=1 ttl=64 time=0.094 ms 64 bytes from 192.168.0.100: icmp_seq=2 ttl=64 time=0.084 ms 64 bytes from 192.168.0.100: icmp_seq=3 ttl=64 time=0.082 ms 64 bytes from 192.168.0.100: icmp_seq=4 ttl=64 time=0.084 ms 64 bytes from 192.168.0.100: icmp_seq=5 ttl=64 time=0.085 ms 64 bytes from 192.168.0.100: icmp_seq=6 ttl=64 time=0.088 ms 64 bytes from 192.168.0.100: icmp_seq=7 ttl=64 time=0.085 ms 64 bytes from 192.168.0.100: icmp_seq=8 ttl=64 time=0.085 ms 64 bytes from 192.168.0.100: icmp_seq=9 ttl=64 time=0.086 ms 64 bytes from 192.168.0.100: icmp_seq=10 ttl=64 time=0.087 ms 64 bytes from 192.168.0.100: icmp_seq=11 ttl=64 time=0.087 ms 64 bytes from 192.168.0.100: icmp_seq=12 ttl=64 time=0.085 ms --- 192.168.0.100 ping statistics --- 12 packets transmitted, 12 received, 0% packet loss, time 10997ms rtt min/avg/max/mdev = 0.082/0.086/0.094/0.003 ms But when I ping the router itself: PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data. 64 bytes from 192.168.0.1: icmp_seq=3 ttl=64 time=32.1 ms 64 bytes from 192.168.0.1: icmp_seq=4 ttl=64 time=2.36 ms 64 bytes from 192.168.0.1: icmp_seq=5 ttl=64 time=1.89 ms 64 bytes from 192.168.0.1: icmp_seq=7 ttl=64 time=1.76 ms 64 bytes from 192.168.0.1: icmp_seq=8 ttl=64 time=1.80 ms 64 bytes from 192.168.0.1: icmp_seq=9 ttl=64 time=1.78 ms 64 bytes from 192.168.0.1: icmp_seq=10 ttl=64 time=1.84 ms 64 bytes from 192.168.0.1: icmp_seq=12 ttl=64 time=1.94 ms 64 bytes from 192.168.0.1: icmp_seq=12 ttl=64 time=3.58 ms (DUP!) 64 bytes from 192.168.0.1: icmp_seq=13 ttl=64 time=1.88 ms 64 bytes from 192.168.0.1: icmp_seq=14 ttl=64 time=1.99 ms 64 bytes from 192.168.0.1: icmp_seq=16 ttl=64 time=1.76 ms --- 192.168.0.1 ping statistics --- 17 packets transmitted, 11 received, +1 duplicates, 35% packet loss, time 15997ms rtt min/avg/max/mdev = 1.765/4.562/32.120/8.323 ms At one point I had 15 consecutive DUP packets during a ping run before things finally settled down. Any idea what could cause this, or how to diagnose it further? I've run "arping -D" and there is only one responder on 192.168.0.1.

rsync question
by Jerry Geis 03 Feb '08

03 Feb '08

I have an external USB that I backup to. Rsync uses a bunch of memory in the process. So I thought I would build the file list and output that to a file then let rsync read the file names from a file list (hopefully not taking TONS of memory)... I do the command: rsync --only-write-batch=rsync_file_list -a /home ./rsync_file_list.sh . seems good and some files do copy. however I get a bunch of messages like: (No batched update for "home/jerry/signisam.nx") and then this file is not copied. Why is that and how can I get it to copy. This all works fine when I execute "rsync -a /home ." as I normally do. Thanks Jerry

USB failure (was: Networking issue (after latest 5.1 update?))

I got one console message about a failed > journal write before the second of those forced reboots. This appears to be happening because the root filesystem is on a USB drive and the system has lost track of the device, as if the cable had been unplugged (even though it was not). I was accidentally able to see this happen while booted from the 5.0 CD in rescue mode, although I can't determine steps to reproduce it. In any case it's probably unrelated to the networking question, and certainly unrelated to the new kernel.

The monitor detects no signal and powers down but I have to remember to do this and I can't always predict how long I'll be away from the monitor. This is a traditional CRT (ViewSonic G220fb) so I'd rather no enrich the power company by supplying power to it for a black screen. Cheers, Dave -- Politics, n.

centos 4.6 and openssl
by Paul A 02 Feb '08

02 Feb '08

Hi, I was compiling a new version of bind on my centos 4.6 server and I discovered that the openssl version (openssl-0.9.7a-43.17.el4_6.1) has several exploits associated with it. I was wondering aside from removing the RPM and compiling a new version of openssl how can I upgrade my current openssl-0.9.7a-43.17.el4_6.1 to a newer version that is affected by the exploits. I know I can yum update openssl as that's is the last version for openssl for version 4. What can I do upgrade openssl? Is it possible to update the server from 4.6 to 5?, is this something that I want to do or is there a better way? TIA, Paul
