CD, VCD & DVD Burning
by John Lange 03 Dec '03

03 Dec '03

At a recent MUUG meeting someone was asking about burning VCDs (Video CDs). I believe the consensus at the meeting was that burning under Linux was comprised of a hodge-podge of various command line tools for converting video formats and burning making it quite difficult at best. I recently stumbled on the following software: http://www.k3b.org/ which seems to bring everything under one roof and claims to do CD, VCD, and DVD burning all in one application (it does not appear to be just a GUI front end to command line tools). However, I do not currently have a burner to test it with so I was hoping someone from the group could give it a whirl and report back on success? Thanks. -- John Lange BigHostBox.com ltd (204) 885 0872 Toll free: 1-866-690-8297

Sendmail stalls with BCC
by Raymond J. Henry 30 Apr '03

30 Apr '03

OK, running RH 7.1 with sendmail 8.11.6. I've done all the applicable updates using up2date. Just today, I notice that I am no longer able to send mail via POP or IMAP when the BCC field is used. From the Windows workstation, it appears to start sending, then stalls. No errors are reported, it just sits there forever. This happens with Outlook Express 6 and Outlook 2000. Not sure exactly when this problem originated, but it's been in the last week or so. A search for this problem on the Internet reveals no clues, nor can I find anything applicable on the sendmail docs. It was working, then stopped. I want to sound like a typical end user, and say that "nothing's changed", but I think something must have. Can anyone point me in the right direction?

According to millward: > Has anyone successfully used a > keyring drive ( those little things with > flash memory and USB connectors ) > with Linux? > I'm told you can use them on any system, > but 'any system' usually means any > MS Windows system. I've used one successfully under Linux. With the 2.4 kernel's USB support, it really is plug-n-play. The device shows up as a SCSI disk, with a single partition containing a FAT32 file system. I just used the mtools to access the files, but you could probably set it up to auto-mount the file system without too much difficulty. The danger there would be that you could accidentally unplug the thing without properly unmounting it first. We've had students wanting to use these on our lab systems, so we recommended they use mtools (to avoid the mounting issues). -- Gilbert E.

keyring drive

Has anyone successfully used a keyring drive ( those little things with flash memory and USB connectors ) with Linux? I'm told you can use them on any system, but 'any system' usually means any MS Windows system.

SOHO Switches
by Brock Wolfe 21 Apr '03

21 Apr '03

I need to do some network upgrading and started looking at 16 port ethernet switches for a small business network. The D-link, LinkSys, 3COM, Netgear, SMC, Ovislink, brands seem to be mostly available for this market niche. Any recommends on make/models or features to use or avoid. Thanks in advance for the advice. Brock

According to Raymond J. Henry: > Thanks to those that gave me input. I did manage to find the problem. I > decided to stop trying to deal with the .htaccess file, and start at the > beginnning. Sure enough, there it was. In the httpd.conf file, AllowOverride > None for the .htaccess control.

That would have been my next guess... :) > Next step is to see how to prevent it from accessing the page when going to > http://hermes.manitobamall.net. I think all you'd have to do is add the following to the .htaccess file... <IfDefine HAVE_SSL> SSLRequireSSL SSLRequire ( %{SSL_CIPHER} !~ m/^(EXP|NULL)-/ ) </IfDefine> In addition, if you would like to have people redirected to the secure port, rather than just getting an error when they come in via http, you can add the following within the IfDefine tags... <IfModule mod_rewrite.c> RewriteEngine on # For testing (logs a lot!): #RewriteLog /var/log/httpd/rewrite_log #RewriteLogLevel 9 # Rather than just deny non-SSL access, we'll redirect to https: # See http://www.apache.org/docs/misc/rewriteguide.html RewriteCond %{SERVER_PORT} ^80$ RewriteRule ^/(.*) https://hermes.manitobamall.net/$1 [L,R] </IfModule> We use a similar trick for our web-based mail software, to force the browsers to use SSL, to encrypt not only the passwords, but also the e-mail content itself. The rewrite/redirect is much "friendlier" than just giving the users an error, IMHO. > Aren't computers fun? <G> I think so! :) -- Gilbert E.

Apache/SSL
by Raymond J. Henry 16 Apr '03

16 Apr '03

Anyone with Apache/SSL experience care to lend a helping hand? I've got Apache compiled with mod_ssl, and it seems to be working fine. In fact, I know that part is working fine. Where my trouble lies is with forcing it to look look for the userID/password to access the directory. It allows any conenction to view the page, without prompting for userID/PW. httpd.conf points traffic for hermes.manitobamall.net to /www/htdocs/manitobamall/. Looked around for everything I could find on the 'Net, and tried all variations of examples, still the same. ____________________ /www/htdocs/test/.htaccess: AuthUserFile /www/pw/.file-password AuthGroupFile /dev/null AuthName "TestPage" AuthType Basic <Limit GET POST PUT> require user test </Limit> ___________________ /www/pw/.filepassword: test: 38sqpB6MNb7BA

Second cup meeting.
by Mike Pfaiffer 16 Apr '03

16 Apr '03

I gather it's going to be on Tuesday of next week (fourth Tuesday of the month). Last time we met around 7:15 although I was told it was to be 7:00. The place is the new Second cup on Portage near Fort (South side). It's not a very large place. Then again there were only half a dozen of us there last time. It's *very* informal. Later Mike
