What is shmfs?

by Andy Stewart

HI gang, After upgrading to a 2.4 kernel, I now see a mounted device thus: Filesystem 1k-blocks Used Available Use% Mounted on shmfs 76220 0 76220 0% /dev/shm I can't find anything written that says what this is. I seem to be able to put files there. Any thoughts? Thanks, Andy -- Andy Stewart Founder Worcester Linux Users' Group Worcester, MA, USA http://www.wlug.org

Hi Andy - Try the VALinux beta 2.4.5 kernel: ftp://ftp.valinux.com/pub/software/kernel/beta USB hasn't been a priority for VA but one of the usb-linux developers is inside the VA kernel group and tends to plug in a bunch of stuff with each of the kernels. Ain't tried it. Let me know what you think. ccb -- Charles C.

Re: [Wlug] USB hangs system - requires reboot

by Andy Stewart

HI Charlie et al, I completely blew away my modules directory and rebuilt my kernel to use uniprocessor (I never did like those canned kernels and canned modules - call me old fashioned but they generally cause me grief). Now, USB works like a champ! I've just printed several docs using CUPS and gimp-print - sweet! Bummer that this doesn't work under SMP...is this a known problem? I doubt my computer is *that* unique. I really would like my SMP back. :-) I did notice one thing - eth0 and usb-uhci are sharing an interrupt. The motherboard magically assigns this and I believe that I can't override it. I wonder if this is causing the problem in SMP mode. I guess I'll keep my eyes open for kernel rev 2.4.7.

Hi Andy - Long time no see. 2 things: That kernel comes with EXT3 already integrated in the source. Once you have an ext3 kernel you can enable it by changing fstab. Disable it by changing fstab. The on-disk structure is the same. Start debugging by booting with the second CPU turned off. You could be locking on MP bug. Used to happen with me and my HP720 OfficeJet until they get their MP act together. ccb -- Charles C.

Re: [Wlug] Any complaints about Charter cable modems?

by Michael Long

It is my understanding that a crossover cable is needed when connecting two similar devices such as 2 switches or 2 routers. Maybe your cable modem has some builtin router functionality?!

USB hangs system - requires reboot

by Andy Stewart

HI gang, I just installed SuSE 7.2 Professional and upgraded to the 2.4.6 kernel (SMP). For the very first time, I'm attempting to enable the USB controller on my motherboard to talk to my Epson 870 printer (which has both parallel and USB interfaces). The onboard controller is an 82371AB. I looked and noticed the following kernel modules loaded: usbcore printer usb-uhci I think this is correct. I've enabled verbose debugging messages in the kernel. I looked at /var/log/messages, and it is detecting my printer. Also, I ran a program called usbview and saw the printer there as well. OK so far. I tried: cat some_file > /dev/usblp0 I get about 1 line of output and then my entire system hangs (it completely ignores any keyboard input, mouse movements don't cause cursor movement, and the machine is unaccessible from the network). I end up reaching for the reset button and waiting forever for my disks to fsck (yes, Tim K. I'm seriously considering Reiser fs). :-) I'm not sure I know how to go about debugging this...any suggestions? Oh, by the way, I did insure that there were no parallel port modules in place that might somehow interfere. Thanks in advance, Andy -- Andy Stewart Founder Worcester Linux Users' Group Worcester, MA, USA http://www.wlug.org

I was not implying a crossover cable was a general solution, just that it was one more thing to try when desperate :-) Frankly I was surprised it worked and still am not sure why :-) doug

I haven't used Charter for very long (2 months at the most) for net access, but I only had a problem once. When I eventually got through on the telephone, they were as stumped as I was (although there had apparantly been a surge of problems that morning in my area) ... modem would shut off whenever the activity LED first blinked. We eventually agreed that a tech would come out and look at it. 15 minutes after I hung up, it was working again. As far as setting it up: when the techs came, I let them mess with my father's Win98 computer. They even ran a new line to the house for better reception. After they left, I rewired a bit. But I got away with a plain cable from the modem to a hub, not a crossover. (on another note... I see they've finally synced chartercom.com and After they left, I rewired a bit. But I got away with a plain cable from the modem to a hub, not a crossover. I'd detail my home network setup, but I'm not entirely sure I totally understand it anymore, after all the changes it's gone through. -- Aaron Haviland orion [at] tribble [dot] dyndns [dot] org Dudley, MA 01571 <jannie> those poor bastards in dimension eyestickjabbing have it worse than all of us (4/3/2001)
