Does anyone have experience migrating legacy COBOL applications to Linux? Just looking for some general advice on what generally needs to be done to accomplish this. Thanks, John

MUUG Meeting, April 10, 7:30pm -- Things you can do with 'Embedded' Devices
by gedetil＠cs.umanitoba.ca 03 Apr '07

03 Apr '07

The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, April 10. The meeting topic for this month is as follows: Things you can do with 'Embedded' Devices The Linksys WRT54G is probably one of the most popular consumer routers around, but for unlikely reasons. Linksys had decided to use Linux as the operating system inside. Linux and hardware hackers around the world started poking around inside. Shawn Wallbridge will be talking about various embedded devices that can be used in interesting ways. The group holds its general meetings at 7:30pm on the second Tuesday of every month from September to June. (There are no meetings in July and August.) Meetings are open to the general public; you don't have to be a MUUG member to attend. ********************************************************************** Please note our meeting location: The IBM offices, at 400 Ellice Ave. (between Edmonton and Kennedy). When you arrive, you will have to sign in at the reception desk, and then wait for someone to take you (in groups) to the meeting room. Please try to arrive by about 7:15pm, so the meeting can start promptly at 7:30pm. Don't be late, or you may not get in. (But don't come too early either, since security may not be there to let you in before 7:15 or so.) Non-members may be required to show photo ID at the security desk. Limited parking is available for free on the street, either on Ellice Ave. or on some of the intersecting streets. Indoor parking is also available nearby, at Portage Place, for $3.00 for the evening. Bicycle parking is available in a bike rack under video surveillance located behind the building on Webb Place. ********************************************************************** For more information about MUUG, and its monthly meetings, check out their Web server: http://www.muug.mb.ca/ Also note that MUUG maintains two mailing lists, called "muug-announce" and "roundtable".

Doing a short BSD presentation for the MWCS next week
by Mike Pfaiffer 30 Mar '07

30 Mar '07

I've managed to install BSD on a 200MHz system (4GB hard drive). The folks at the MWCS were so impressed they asked me to do a demo. It seems to be working really well. I've even got KDE running (not enough room for Gnome). I don't have the sound configured yet. Can anybody think of something to wow some *NIX newbies? I was planning on letting them play around on the machine for 45 minutes while I talk about the similarities and differences between BSD and Linux. I'm a BSD newbie myself (It's been about a week since I got it running) so I'm not sure of what I can say. Later Mike

Changing file associations in gnome / Evolution?
by John Lange 29 Mar '07

29 Mar '07

For anyone on this list that doesn't already know; I've become a huge SUSE fan since the 10.X series came out. I think its by far the best desktop going (yes; even better than Ubuntu). Ok, that's my soapbox speech.... Now on to the problem; there is one dang thing that drives me up the wall that I have never been able to sort out and I assume its not limited to SUSE. I use Evolution and the gnome desktop; even though I have the file associations set in gnome (via Nautilus), Evolution doesn't seem to use them. So for example, the one that constantly frustrates me is attachments with the file extensions in a different case. Damn Windows users are constantly sending me message.WAV, or fax.TIF files and evolution only recognizes .wav or .tif so I have to do a "save as" and then open them in Nautilus. So the question is what is the proper way to set file associations in gnome so that Evolution will use them? Evolution reportedly uses the gnome settings to figure out what to do with files so I assume that using Nautilus to make these changes is not the correct way to do it? Most of the google results on this topic seem to point at methods for older versions of gnome that does not work with this version of SUSE (OpenSUSE 10.2). John

bringing background app to front
by Montana Quiring 16 Mar '07

A friend of mine asked the question: "Is there a commandline utility that can bring a running application such as xmms to the foreground?" I wonder if it might be WM specific.

minor DST problem with Red Hat/Fedora "legacy" systems
by Gilles Detillieux 14 Mar '07

14 Mar '07

If you're still running Red Hat or Fedora Linux systems that were being updated by the Fedora Legacy project before it was shut down, you should have received the tzdata update last year to correct the Daylight Saving Time switchover for this year. However, the updates from fedoralegacy.org only installed the new /usr/share/zoneinfo files, but didn't update /etc/localtime from that. (On RH/FC systems, /etc/localtime is a copy of the appropriate zoneinfo file, not a symbolic link.) What I found is that for these systems (RH9, FC1-3), I needed to do the following: cp -p /usr/share/zoneinfo/America/Winnipeg /etc/localtime After that, I either rebooted the system, or restarted these services: syslog, crond, xinetd, sendmail, httpd. FC4 updated itself automatically last spring, so as long as you rebooted since then, the DST change should have happened without a snag. FC5-6 had the changes at release time. I also managed to update a very old Red Hat 6.2 system by copying the zoneinfo file from a Red Hat 9 system updated by fedoralegacy. Just thought these tips might be of help if you're supporting legacy linux boxes. -- Gilles R.

Protip: dealing with remote terminals, and /proc/pid/environ
by Scott Balneaves 12 Mar '07

12 Mar '07

Hello all Bumped into something I needed to do this morning, thought others may be interested. I needed to get an accurate count of how many 15 inch monitors I had on my LTSP network. One can, of course, get this from xdpyinfo, but I can't ssh into clients to do this. What to do, what to do... Well, of course, what I need to do is set my $DISPLAY and $XAUTHORITY environment variables correctly, so I can run xdpyinfo. But, how to find out who's on what terminal? Well, since everyone runs metacity as a window manager: pgrep metacity returns a list of process id's. From there, we can look in /proc/<pid>/environ, and get some more info! But hold on: cat /proc/3660/environ returns: SSH_CLIENT=192.168.0.229 443422USER=foobarMAIL=/var/mail/foobarGNOME_KEYRING_SOCKET=/tmp/keyring-awvD15/socketSSH_AGENT_PID=3510 etc. Environment variables are null terminated! So, how to get around that? As usual, there's a quick easy way to do it: tr to the rescue: cat /proc/3660/environ | tr '\0' '\n' SSH_CLIENT=192.168.0.229 4434 22 USER=foobar MAIL=/var/mail/foobar GNOME_KEYRING_SOCKET=/tmp/keyring-awvD15/socket etc. Hey! Fit for using with eval! Here's the whole script, just for fun. #!/bin/bash for PROC in $(pgrep metacity); do eval $(cat /proc/$PROC/environ | tr '\0' '\n' | grep SSH_CLIENT | awk '{print $1}') eval $(cat /proc/$PROC/environ | tr '\0' '\n' | grep USER) export DISPLAY=$SSH_CLIENT:6 export XAUTHORITY=/usr/legal/home/$USER/.Xauthority echo -n ${USER} xdpyinfo | grep dimension done Hope someone finds this useful.
