Howdy folks! I thought I'd pass this along to the MUUG mailing lists. I'll likely announce it at the next MUUG meeting, but the April 1st early registration deadline will have passed by then. MUUG is not sponsoring or in any way affiliated with this event, but I thought it might be of interest to members... -- Gilbert E.

Obviously, security is an area of interest that MUUG and IPAM members share. MCISC brings together the implementers and developers of the hottest information security technologies. The conference avoids the "just another sales presentation" stigma and gets world experts to deliver real technical education to attendees. While the conference is supported by vendor sponsorship, the event is totally non-profit, is offered at a reasonable attendee cost ($50 including lunch till April 1), and helps further the goals of IPAM, which are: * To bring together industry professionals to present and discuss information security challenges and solutions. * To build understanding of the most recent trends and developments in the industry. * To share ideas, experience and insights into technical aspects of information systems security. * To enhance management and control of information systems security. * To develop contacts with other individuals, organizations and suppliers in the industry. I would be happy to provide any additional information about the conference for your membership. _____ Shawn Lukaschuk - IPAM MCISC Chair mcisc(a)ipam.mb.ca <http://www.ipam.mb.ca/mcisc2003/link.htm#> http://www.ipam.mb.ca/mcisc2003

Detillieux) The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, March 11. The meeting topic for this month is as follows: Wiki and TWiki Wiki is a piece of server software that allows users to freely create and edit Web page content using any Web browser. Wiki supports hyperlinks and has a simple text syntax for creating new pages and crosslinks between internal pages on the fly. We will focus on a Wiki implementation called TWiki, a flexible, powerful, and easy to use Web-based collaboration platform. Use TWiki to run a project development space, a document management system, a knowledge base, or any other groupware tool, on an intranet or on the internet. Web content can be created collaboratively by using just a browser. Developers can create new web applications based on a Plugin API. Bill Reid will be presenting this month's topic. The group holds its general meetings at 7:30 PM 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 new 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 7:15 PM, so the meeting can start promptly at 7:30 PM. Don't be late, or you may not get in. Limited parking is available for free on the street, or in a lot across Ellice from IBM, for $1.00 for the evening. Indoor parking is also available nearby, at Portage Place, for $2.00 for the evening. ********************************************************************** 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".

Re: [RndTbl] Using math routines (math.h, header files) in C programs.

That's the way it's defined on my system anyway. It's best to always check the man pages for the functions first, to be sure about their names and expected argument types. > Shell session showing error message: > $ gcc -o example example.c > /tmp/cc4fVMFv.o: In function `main': > /tmp/cc4fVMFv.o(.text+0x12): undefined reference to `sqrtf' > collect2: ld returned 1 exit status > $ It may also be necessary to include the "-lm" option explicitly, at the end of the gcc command line, to have it link against the math library.

You'd only have to do that if the libraries you wanted to use weren't in the usual library search path. Hope the above helps. -- Gilbert E.

Using math routines (math.h, header files) in C programs.
by Ihor Jakowec 04 Feb '03

04 Feb '03

I was attempting to use the math routines of the libc library. The following program (listed below), would not compile. A shell session, showing error messages, follows the source code. Source code: #include <stdio.h> #include <math.h> int main (void) { printf("The square root of 2.0 is: % .6f\n", sqrtf(2.0)); } Shell session showing error message: $ gcc -o example example.c /tmp/cc4fVMFv.o: In function `main': /tmp/cc4fVMFv.o(.text+0x12): undefined reference to `sqrtf' collect2: ld returned 1 exit status $ Setting path and and gcc environment variables did not make the program compile. Is this feature (math.h), fully implemented or, unsupported or, depreciated? Please, tell me what to do to get this program to work. -Ihor

MUUG Meeting, Feb 11, 7:30PM -- Wireless Network Setup and Security
by gedetil＠cs.umanitoba.ca 04 Feb '03

04 Feb '03

[Posted to man.unix.general and other new groups] ------ Forwarded Article <b1oue1$im7$1(a)canopus.cc.umanitoba.ca> ------ From gedetil(a)cs.umanitoba.ca (Gilbert E. Detillieux) The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, February 11. The meeting topic for this month is as follows: Wireless Network Setup and Security Wireless networks are becoming a popular alternative for home users and small businesses. A small LAN can be installed more quickly (and sometimes more cheaply) with standards-compliant wireless equipment than with traditional ethernet wiring. Unfortunately, many users value the flexibility of wirless networks without recognizing the security risks involved. Adam Thompson will discuss and demonstrate connecting a RedHat 8.0 system to an existing ethernet infrastructure and, time permitting, configuring WEP (Wired Equivalent Privacy). The group holds its general meetings at 7:30 PM 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 new meeting location: The IBM offices, at 400 Ellice Ave. (between Edmonton and Kennedy).

*BSD and PCMCIA networking
by Glen Ditchfield 20 Jan '03

Last month I wrote > Just for the heck of it, I installed NetBSD 1.6 on an old laptop. > ... . I've looked around, but I don't see any way > to configure what happens during [PCMCIA] card ejection and insertion > events. Am I missing something? > Do the other BSD variants handle PCMCIA differently? Well, just for the heck of it, I installed FreeBSD 4.7. It does have a system to handle PCMCIA events; see the man pages for pccardd and pccardc. It correctly handled my network card right out of the box.

The guys who host the our Digital Civilization domain said they could do a presentation if asked. They run their ISP using Mandrake and a couple of other *NIX distros. They also operate the Penguinista advocasy site. The guy who runs Mac Helper on St. Marys might be persuaded too. Interested?

Re: CD-RW installation
by gedetil＠cs.umanitoba.ca 15 Jan '03

15 Jan '03

According to Mel Seder: > Hi Gilbert, Hi Mel. I decided to post my reply to the roundtable list, in case it's of use to others too... > Can you please run those instructions by me again? > > My son-in-law is running Red Hat and 8.0 and he connected a CD RW drive. > > What steps do I have to take to get the drive working in linux? First, add the following line to the /etc/modules.conf file... alias scsi_hostadapter ide-scsi Then, you need to build an "initrd" file for your kernel, to load the ide-scsi driver automatically on system restart. Check your kernel version number by looking in /boot for the vmlinuz-* file(s). For example, if you have a kernel called vmlinuz-2.4.18-19.7.x, you'll want a corresponding initrd file called initrd-2.4.18-19.7.x.img. (There may already be one if the installer figured you had other drivers that needed preloading.) You'd build (or rebuild) the initrd file as follows... mkinitrd -f /boot/initrd-2.4.18-19.7.x.img 2.4.18-19.7.x The -f option will force an existing file to be rebuilt. The next argument is the initrd file name, and the last argument is the kernel version number (so it knows which /lib/modules directory to get the modules from). If you've got multiple kernels installed, you may want to repeat the above for each of the kernel versions you've got. Certainly, you'll want to do it for the kernel that gets booted by default. Next, you have to tell your kernel boot loader (grub or lilo) to load that initrd file when it loads the kernel. If you're using grub (you should, as long as you're running a distribution that supports it), edit /etc/grub.conf (or /boot/grub/grub.conf, which is what /etc/grub.conf should point to), to add the following line... initrd /boot/initrd-2.4.18-19.7.x.img You would add that just after the kernel line for the corresponding kernel version (adjusting the kernel version as required), such as... kernel /boot/vmlinuz-2.4.18-19.7.x ro root=/dev/hda2 (Of course, if you already had an initrd file in /boot, the grub.conf file may already mention it.) If you're using lilo instead, edit /etc/lilo.conf to add the following line... initrd=/boot/initrd-2.4.18-19.7.x.img ... in the section for the appropriate kernel image, then run the "lilo" command to update the lilo boot record and map file. After that, you can reboot, and the driver should load automatically. If you're using grub as the boot loader, there's the added advantage that anytime you upgrade your kernel, it will automatically build an updated initrd file and update the grub.conf file, so there's very little you have to worry about. With lilo, unfortunately, you'll have to repeat the lilo configuration changes above manually each time you upgrade your kernel. -- Gilbert E.

Second Meeting
by Shawn Wallbridge 08 Jan '03

08 Jan '03

As discussed at the December meeting, we are thinking of having a second, fairly informal 'roundtable' meeting. Since it was mid-December and most people were probably a little busy with the holidays, we didn't plan a meeting. But I think one in late January would be a good time. If people have any suggestions where to have the meeting and when, please bring them up on the roundtable list. shawn
