[arch-general] Hard lockups during boot
by Chris Bannister 22 Jul '10

22 Jul '10

Hi, I used to use a zen kernel but that stopped working which is an unrelated story so I switched back to the Arch kernel, but im getting hardlocks during boot. It happened twice just now, first time was after ATA got init'd but before the SCSI came up. The second time it got to the waiting for udev .. during userspace init. Heres the attached working dmesg log [1] in case its of anyhelp. I didnt want to post this to the bug tracker because of the lack of logs I can provide so ill put it here and if anyone has any ideas please shoot them over. Thanks!

[arch-general] simple iptabels question
by aerospace1028＠hotmail.com 22 Jul '10

22 Jul '10

Hello, I have a question on iptables. On the arch wiki, the tutorial on a simple stateful firewall includes the creation of the following rule. # iptables -A INPUT -p tcp --syn -m state --state NEW -j OPEN-TCP Which, to my understanding, meant only pass new TCP streams with the syn flag (the initialize connection or handshake part 1 of 3) to the user defined chain. When I checked the output of iptables, I noticed the following rule. # iptables -L INPUT --line-numbers -v 7 OPEN-TCP tcp -- anywhere anywhere tcp flags:FIN,SYN,RST,ACK/SYN state NEW Why is iptables also using the FIN, RST and ACK/SYN flags? Did I not request SYN only like I thought the tutorial said? _________________________________________________________________ The New Busy is not the old busy.

[arch-general] Archlinux Wiki Backup
by Francesco Turco 22 Jul '10

22 Jul '10

Hello, As I said in the forums (https://bbs.archlinux.org/viewtopic.php?id=94201), I started contributing to the wiki (minor edits for now), but I'm concerned about the absence of a proper way to obtain a snapshot of it for backup reasons. I looked at the arch-wiki-docs package, but it's only a collection of HTML pages, with no source code, no discussions, no revisions, and not working hyperlinks. This way, it would be hard to restore the wiki after a crash. Other wikis provide a backup: please see http://download.wikimedia.org/ and http://en.gentoo-wiki.com/wiki/Gentoo_Linux_Wiki:Backup. To reduce bandwidth usage, we can use Bittorrent, just as with ISO releases. What do you think? Thanks.

[arch-general] All kdemod3 menu apps in "Lost & Found" menu folder + control panel apps gone - how to get back?
by David C. Rankin 21 Jul '10

21 Jul '10

Guys, Help! Something (probably that fricking kde4) has caused almost every menu item to end up in the "Lost & Found" kde3 menu folder off the main menu. I don't know where that folder is so I can try an move the items back. Also, what ever happened also caused all kde3 control panel entries to disappear from the control panel. Now I don't have a control panel any more: 23:22 alchemy:/opt/kde/share/applications/kde> kcmshell --list The following modules are available: Huh? The only thing I have done menu wise is to edit the Gnome menu, but that shouldn't have trashed my kde3 menu and control panel. Can anyone offer any ideas where all the missing apps are. Where is this "Lost & Found" place all the menu items went? Here is a screenshot of what I see when I move over the "Lost & Found" menu item. (131k) http://www.3111skyline.com/dl/Archlinux/bugs/kde3-lost+found-menu.jpg It is frustrating as hell to have everything setup just the way you like it and then have some unrelated process fsck it all up. I've been in gnome for the past week or so and this is the first time I've booted back to kde3. Go figure. Any ideas? I have had the disappearing menus and control panel issue before in kde3 on SuSE, but never in Arch - now Arch has been bitten by this bug. Hopefully we can find the cause. Surely alacarte is to blame... Is it? -- David C. Rankin, J.D.,P.E.

[arch-general] $BROWSER variable and Google Earth
by F. Gr. 21 Jul '10

21 Jul '10

Hi, Google Earth can't recognise the $BROWSER environment variable. I've set the one in my '~/.zshrc' as follows: " export BROWSER="/usr/bin/icecat" " When I try to open an external link I get the following error: <http://www.imagebam.com/image/a79e8989327021>. That Italian message means: "cannot start up a web browser. Check to have set the $BROWSER environment variable to the web browser filename you want to start up." I don't know why. Cheers

[arch-general] IPTables DDoS
by Nilesh Govindarajan 21 Jul '10

21 Jul '10

Hi, Can someone tell me how to use IPTables to prevent DDoS attacks? I'm sure IPTables has the relevant modules (limit, recent I think) after reading some docs, but still in doubt about its implementation. -- Regards, Nilesh Govindarajan Facebook: http://www.facebook.com/nilesh.gr Twitter: http://twitter.com/nileshgr Website: http://www.itech7.com VPS Hosting: http://j.mp/arHk5e

[arch-general] perl-authen-sasl: local (2.1401-1) is newer than community (2.15-1)
by Damjan Georgievski 21 Jul '10

21 Jul '10

This is what happens to me now # pacman -Syu ... :: Starting full system upgrade... warning: perl-authen-sasl: local (2.1401-1) is newer than community (2.15-1) I guess this happens because I have installed something from testing at one point, and anyway, I know how to override this warningm but.. The question is, should pacman think that 2.1401 is newer than 2.15 ? -- damjan

This approach guarantees that someone using ABS to build packages will not get screwed and gives people supposedly reproducible results. I personally export a lot of variables in makepkg and set their values in "makepkg.conf". I even use a convenience variable "$GVER" which is set now to "45" in my system. It's also a good idea to add the dirname of the correct "libstdc++.so" to "$LIBS". Linking against different "libstdc++" versions is not fun. Using the correct "$GVER" can take care of all that. I'm not sure this will work with the way Arch packages gcc though.
