taking a hack at /etc/group

by d.maly＠ieee.org

I stumbled across bug #48545 (https://launchpad.net/distros/ubuntu/+source/control-center/+bug/48545) when sound wouldn't work only for the "primary" user ('me') ... it *did* work for the other users on this computer, including others with access to root. The fix is to add 'me' to the audio line in /etc/group: audio:x:29:user1,user2,user3,me In the meantime, I noticed there were several lines in this file which included all users except 'me'. So here's the question: should I add 'me' to all such lines? Seems too crude ... and there must be some file "upstream" that would lead to 'me' being left off in the first place ?? Thanks, Doug

Problem w/gcc

by Eric Martin

My laptop has been doing weird stuff lately. I built it a while ago from Gentoo 2006.0 Stage 3, and every now and again it would turn off while compiling something (usually if I had to upgrade glibc). I was just trying to update mythtv and it crashed so I decided to level it and start from scratch. I installed Gentoo 2006.1 Stage 3 and it's doing the same thing. I went down to Stage 2 and I'm still having a problem. I've done memtest in the past with clean results, but I'm stuck because I don't know what the error is. While building a few minutes ago I forgot to turn on swap space and it ran out of memory before crashing (turning off). Is there anything I can do aside from piping the output to a file to capture what the problem might be (tried it, not much help)? Has anybody had similar problems with gcc / glibc? Thanks in advance Eric

The graphics (motherboard) on my linux box have stoped... I still have an ascii screen, but no graphics. (No errors in any logs, so I suspect a hardware failure.) I'm looking for a cheap PCI graphics card to see if that fixes the problem. Even a loaner would help. Thanks, Bill

Is your VPN endpoint on the home computer, or is it on the Linksys box? That would be the deciding factor. If it's on the computer, then I'd doubt that going to the Linux compatible router hardware (or just updating the firmware) would have any impact at all on the VPN. Good luck! John

I know as much as I posted this morning, as I just found out. Patching the client seems like a good idea, but I'll bet that the problem is due to Linksys being out of spec to accommodate a Windows "enhancement" and the Linux folks are not going to patch that on principal. -- Gary

Re: [Wlug] Linksys Router

Hello Gary, I assume you mean WRT54GS ;). According to <http://www.dd-wrt.com/wiki/index.php/What_is_DD-WRT%3F#Supported_Devices>, the dd-wrt open firmware supports some versions of your router. If you cannot make your Linux dhcp client work, you might try changing the firmware on your router to support Linux. If you want to change routers and you are interested in the Linux open firmware, then <http://www.dd-wrt.com/wiki/index.php/What_is_DD-WRT%3F#Recommended_Devices> has some good suggestions. -Adam On 12/16/06, jmoyer(a)redhat.com <jmoyer(a)redhat.com> wrote: > > ==> Regarding [Wlug] Linksys Router; Gary Hanley <gary(a)hanley.net> adds: > > gary> I recently upgraded my router to a WRT45GS and have been having a > gary> bear of a time trying to figure out why, when I boot Linux, I can't > gary> get an IP address from the router but with Windows I can. > > gary> It worked with the old router.

I recently upgraded my router to a WRT45GS and have been having a bear of a time trying to figure out why, when I boot Linux, I can't get an IP address from the router but with Windows I can. It worked with the old router. It works with Windows. There are no DHCP tweaks in the router. What the hell is wrong? Turns out that there a bug in the router.

Fuse and other users

by Jamie Guinan

The other night I was trying to find the code where FUSE [dis]allowed other users to access files, but I couldn't remember where it was. Found it in fs/fuse/dir.c, /* ... * For this reason only those processes can call into the filesystem, * for which the owner of the mount has ptrace privilege. This * excludes processes started by other users, suid or sgid processes. */ static int fuse_allow_task(struct fuse_conn *fc, struct task_struct *task) { if (fc->flags & FUSE_ALLOW_OTHER) return 1; if (task->euid == fc->user_id && task->suid == fc->user_id && task->uid == fc->user_id && task->egid == fc->group_id && task->sgid == fc->group_id && task->gid == fc->group_id) return 1; return 0; } The FUSE_ALLOW_OTHER flag is set when you invoke a fuse program like sshfs with "-o allow_other". -Jamie

Fuse "slides", other notes

FUSE presentation, http://www.bluebutton.com/wlug/fuse-presentation/index.html Thanks for putting up with the delays due to my ill-preparedness in forgetting my port-replicator, and big thanks (again) to Frank S. for hooking me up with the Mac laptop. Before we settled on using the Mac, I was going to try this, http://www.karlrunge.com/x11vnc/ but it was slow to install and I didn't want to delay the presentation any further. It lets you export your whole X display over VNC. I just tried it on a system here, and it does work - in fact, if you run the viewer on the same host, you get an "infinite hall of mirrors effect", like pointing a webcam at your monitor, http://www.bluebutton.com/wlug/x11vnc-hom.png A useful tool for remote access, AND for Cthulhu to inflict non-euclidean madness on X11 users! :) Happy holidays all! -Jamie
