Stopping a server not controled by service
by Robert Moskowitz 16 Jul '08

16 Jul '08

Miredo is run as a server from the command line: /usr/sbin/miredo The man page says the signal SIGTERM stops the server. How do I send SIGTERM to the server? Or SIGHUP, as I want to make a change to the config file. And once I get this as I want it, how do I run it at system boot?

RADVD and default IPv6 gateway
by Robert Moskowitz 16 Jul '08

16 Jul '08

the man page for RADVD says: radvd is the router advertisement daemon for IPv6. It listens to router solicitations and sends router advertisements as described in "Neighbor Discovery for IP Version 6 (IPv6)" (RFC 2461). With these advertise- ments hosts can automatically configure their addresses and some other parameters. They also can choose a default router based on these adver- tisements. But there is nothing I see in man radvd.conf that answers how hosts choose a default router, nor can I find anything else about this. Anyone know the answer or where to get the information???

Documentation file for ifcfg options
by Robert Moskowitz 16 Jul '08

16 Jul '08

Sometime in the past two weeks, Some kind person pointed me to a GREAT document file that explained all those commands you find in the ifcfg-* files and the network file (and others, I believe). It was a great help to me, and now I need it again, and I did not write down the file location, nor can I find that original note. My bad, I am busy documenting everything I can now. But I really need that info. Can someone point me to file again?

Bug-buddy and bug reports for GNOME 2.16...
by MHR 15 Jul '08

15 Jul '08

There seems to be some hostility to the idea of this being a GNOME or Evolution problem: Bug 542280 – Refuses to report bugs because gnome 2.16.x is too old View Bug Activity Product: bug-buddy Component: general Version: 2.16.x Status: RESOLVED Resolution: WONTFIX Opened by Mark Hull-Richter (reporter, points: 3) 2008-07-09 23:40 UTC [reply] On CentOS 5.2 (and 5.1 and 5.0, and Red Hat Enterprise Linux of the same versions, which happen to be the most current ones available), the bug buddy "tool" consistently refuses to report any bugs because it claims that the version of Gnome is too old. This is unacceptable - Gnome 2.16.x is the /standard/ release with RHEL and CentOS distributions of Linux/Gnome. There are too many issues that can (and do) come up for the tool simply to refuse to report a bug for this reason. Comment #1 from Cosimo Cecchi (points: 22) 2008-07-14 20:29 UTC [reply] This is intentional and isn't a bug-buddy issue. Bugzilla only accepts crashers from the two most recent stable releases (e.g. now that 2.22 is the current stable, it rejects everything <= 2.19.99). This is because we can't support every stable branch, as the codebases evolve and backporting fixes would be nearly impossible. If you need a specific fix, please backport it yourself in your distribution (like RHEL does I think) or just use newer releases. I'm closing this as WONTFIX, please file a bug under bugzilla.gnome.org component if you need more explanations, thanks. Comment #2 from Andre Klapper (points: 28) 2008-07-14 20:46 UTC [reply] It's not our problem that CentOS and RHEL ship ancient software. Ask them to patch bug-buddy to report against their distribution bug tracker instead of GNOME Bugzilla. We are definitely not interested in bugs that probably have been fixed for ages and 95% of those ancient reports are dups anyway. If you volunteer to triage all that useless incoming stuff, okay. We definitely don't want to, we got better stuff to spend our time on than 2.16 that in fact nobody works on, except for two LTS distros. LTS? Long Term Support? So much for that effort. Any chance of CentOS (or RHEL) patching bug-buddy as suggested in #2, above? Just curious.... Thanks, all. mhr

r8169-driver CentOS5.2
by Simen Timian Thoresen 15 Jul '08

15 Jul '08

Hi all, Another FYI-mail (and just to verify that I'm not going insane here); I recently purchased an ASUS M3A78-EMH HDMI -board with a tri-core Phenom. This is a small uATX-board with all the garnish integrated motherboards are supposed to come with, and fairly well supported in CentOS 5 and other modern distros. When I installed it (~2 months ago) the NIC was not supported; Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02) ...but Realtek provided a 2.6-kernel compatible r8168-driver; r8168-8.006.00 When the CentOS 5.2 updates were published, I saw to my happiness that the kernel-supplied r8169-driver now handled the NIC, and I had no reason to rebuild the r8168-driver to support the new kernel. Last time I rebooted, was July 2nd, to the 2.6.19-92.1.6.el5 kernel. Since then, the kernel supplied r8169-driver worked like a charm. The machine is a home file-server, serving files over NFS and SMB, and runs my torrent downloads. It also pulls CentOS updates. I would have noticed if it did not work. Today, I got around to replacing a failed disk, and after rebooting I had no network connectivity. The NIC displayed 'weird' symptoms; 10Mbps link as shown by ethtool, 100Mbps link as shown by the link-indicator on the switch, ifconfig showed no TX-packets, some RX-packets, /billions/ of dropped packets - increasing by millions every second. The kernel log showed multiple 'Link down' entries. After digging around a little, swapping switch-ports, yattayatta, I unloaded the r8169-module (rmmod) and built and loaded the Realtek-supplied r8168-module. Link up, packtes going in and out, no dropped packets, GigE link, etc etc. At this point I have no idea what actually happened. I'm thinking some weird state on the PHY of the NIC (I've seen this on the Nvidia NICs) that was not flushed due to a too short power-loss, or possibly that the r8168-driver sets some PHY-state that was not lost at the kernel-update that brought me the 'working' r8169-driver, or something similar. I'm taking suggestions, tho. Anyone else with this same board, CentOS 5.2 (x86_64) and using the r8169-driver? -S -- Simen Thoresen, Dolphin ICS Systems Administration and Wulfkit Support

Miredo relay port question
by Robert Moskowitz 15 Jul '08

15 Jul '08

I am bringing up a Miredo server and relay on my new iPv6 network. I have been reading the RFC and the man pages. One of the many vague points is the udp port used by the Miredo client in relay mode. Is it 'random' or is it 3545? How do I find out what it is? Plus how do I set up my server so that the Miredo server and client relay start as part of the system boot? They do now work with the service command, but just running them from the command line starts the server. My digging so far has not given me these answers....

vncviewer via gateway option question
by Robert Moskowitz 15 Jul '08

15 Jul '08

the man page for vncviewer presents the -via gateway option to use ssh through a gateway. I understand if I want a secure vnc connection to server.foo.com I can use the command: vncviewer localhost -via server.foo.com But I have moved my SSHD services from port 22 to port n. So according to the man pages, I need an environment variable of VNC_VIA_CMD and override the default command with: /usr/bin/ssh -p 7722 -f -L "$L":"$H":"$R" "$G" sleep 20 where 7722 is the port for sshd. How do I set up this environment variable on my notebook. Would I modify my .bash_profile file, and is the format of the added line: VNC_VIA_CMD=/usr/bin/ssh -p 7722 -f -L "$L":"$H":"$R" "$G" sleep 20 ???
