Doing a quick grep on nfs in the changelogs - I received several hits - so the problem may have been addressed. If after testing this with the latest stable release and prepatch release - I would then resend the bug report. I would also send the bug report to - mailto:linux-kernel@vger.kernel.org - this is the main kernel mailing list. When sending to this list indicate that you sent the message to person xyz and received no response and ask who the current maintainer for the nfs code is. If you get a different name as the maintainer - resend the report to that person. You may want to take a look at the following URL for reporting kernel bugs: http://www.kernel.org/pub/linux/docs/lkml/reporting-bugs.html Your bug report is fairly thorough and should suffice. Remember that the person you sent the bug report to just may be very busy (such as they may do this in their own free time) and has not got around to it yet or may have dropped it on the floor if the problem has already been solved. Don't be afraid to resend the bug report if the problem does still exist in the latest pre-patch release. Also if you don't get anywhere that route - try going to http://kernelnewbies.org/ - they have a few mailing lists and an IRC channel where you might also get some responses. Good Luck! - Tom

Re: [Wlug] ssh-dummy-shell for OpenSSH???

by Scott Venier

does the ssh-dummy-shell have to actually do anything for sFTP to work, or does it just have to be in /etc/shells? If it just has to be in /etc/shells, /bin/false works. Been using that for years for (non-s)FTP-only accounts. Scott On Wed, 30 Jan 2002, Keller, Tim wrote: > I'm setting up a test environment using OpenSSH built in sFTP server.

ssh-dummy-shell for OpenSSH???

by Keller, Tim

I'm setting up a test environment using OpenSSH built in sFTP server. What I want to-do is build a chroot environment where people can connect to the machine via sFTP but not via SSH. I know with the commercial version of SSH they have ssh-dummy-shell which when you try to connect via SSH just bails on you, but lets sFTP work properly. I've done some digging on the web and I haven't found anything that'll replace this functionality on the OpenSSH side of things. Anybody got any ideas/links of an open source version of ssh-dummy-shell. Thanks, Tim.

Bug reporting?

by Bill Mills-Curran

How do I report a bug (or at least ask for help) in a newer kernel? (The gory details are below, if you are interested.) I sent some email to a developer whose name I found in the suspect source, but I did not get any response. Any suggestions? TIA, Bill **************************************************************** Date: Fri, 25 Jan 2002 14:40:01 -0500 (EST) From: Bill Mills-Curran <Mills-Curran_Bill(a)emc.com> To: claus(a)momo.math.rwth-aachen.de Subject: nfs readdir bug? Claus, I am reporting a bug that I suspect is in nfs readdir. I am reporting it to you, because I found your email address in the source. If this is wrong, please tell me. Symptom: Several programs (details below) do not read the contents of an nfs-mounted directory. There is no indicated failure -- there just is no data. The nfs server is DG/UX. The nfs client is linux, kernel version 2.4.16. The problem does not show up with the 2.4.2 kernel (RedHat 7.1 dist.) or on nfs systems from a SUN server. Note: We are using reiserfs on an array which is locally mounted to the linux host. The hardware is: DG (Data General) Aviion 8900 4 cpu, 500 MHz. strace note: I ran strace on my program. It reported that getdents64 function was finding the right number of directory entries. **************** These operations/programs fail to read a directory. In all cases, the OS is linux 2.4.16 and the filesystem is served by DG/UX. All directories (that I tested) on the filesystem have the problem. tcsh file completion (using the tab key) readdir in Perl readdir in my own test program (included below) **************** These operations work with the 2.4.16 kernel. All operations on other filesystems, nfs (SUN server) and local The "ls" command works everywhere Thanks for your time.

Zork was also slashdotted yesterday (the article about the "begin " and other anti-LookOut tricks Nick Moffitt [a.k.a. Crackmonkey] [the guy who owns zork.net/crackmonkey.org] uses in his emails). Afaik, he had previously had apache set up so that zork was the default virtualhost. I can't say why he may have changed it. The reason (as i understand) that archives are stored on zork instead of on the lnx-bbc site, is that Nick is developing GAR (a linux clone of ports, done with Makefiles) for lnx-bbc. If you need help with this specific version of lnx-bbc, you might find some willing volunteers on #tron, irc.slashnet.org. just be sure not to use a proprietary IRC client or OS... -- Aaron Haviland orion [at] tribble [dot] dyndns [dot] org orion [at] zork [dot] net Canadians are from Canadia.

After that you can install anything you like. At last count, they had between 700 and 800 packages you could install. Iy's dependency based, so if you say you want to install kde, it will install X and a bunch of other stuff so you can run kde. You still need to know a bit about what you're doing, but it's a very promising distro. --Skip

video card problems (I think)

by avedis＠ma.ultranet.com

Hi all. I'm lost trying to install suse 7.2 on a P166 with an ELSA GLoria vid card. I'm getting quite experienced with the different xfree setup utilities. When I was installing the software, I couldn't get past the video test and could only install text mode. If I use xf86config and use the vga16 driver, I can get into X, but all I see is the background color, and the only way out is ctrl-alt-back. I had to manually edit /etc/XF86Config to get rid of the 800X600 virtual screen and force it to 640X480. I did that so I could use sax without it going offscreen and out of reach of my mouse. Oh yeah, sax wasn't able to do the job, and sax2 told me I was using XFree v.3 and promised to install v.4, but it just hung totally - blank screen, hit the reset button to reboot. Using XF86Setup, I was able to install the XF86_3DLabs server (the right one) and can now get as far as the KDE desktop starting to open. It hangs when it's checking peripherals. Does that mean that some hardware is not set up properly, and if so, how do I find out which it is? Many thanks if anyone can point me in the right direction. Greg

Neither have I! :-( / :-) That was a screw-up spelling checkers can't catch! It should have been LYX-BBC as in http://www.lnx-bbc.org/ Sorry about that. As you can see I can do more than just pull out power cords! :-) Thanks for the background on host-based virtual hosting; now I can go back to seeing whether I can find a work-around in that context. doug
