meeting topic
by Mike Leo 01 Feb '06

Am I wrong, or is the gentoo install insanely comlicated? Although I did not sit in front of it from start to finish, it seems like an install takes hours and hours of work... I followed the Handbook (some 80 pages of documentation), which i'm sure is very accurate and each step worked as advertised, but in the end it was too much. After an install of debian, which takes me less than 20 minutes, this was too much for my poor little brain to take, and I eventually gave up. In addition to that, I can't for the life of me, get slackware to consistantly install lilo correctly during the install. Any comments on either of these would be apreciated, however, I am just writing this to toss my vote in for a linux install fest as a meeting topic. I have no problem bringing in a laptop to show the simple, eligant, streamlined, 20 minute debian install, but I would like to also see someone go through a gentoo install, and assist on a slackware lilo config...all of which can be done via my laptop if needed. Thanks ! Mike

You can get up to 1/8192Hz (122us) periodic interrupts with the x86 RTC timer. You might have to do a little setup, like, # modprobe rtc # echo 8192 > /proc/sys/dev/rtc/max-user-freq [ fiddle permissions on /dev/misc/rtc or /dev/rtc unless you are running your app as root ] See Documentation/rtc.txt in the kernel source for programming details. Basically the kernel is free to idle or run other things until the RTC interrupt hits, then it wakes up your app doing read() or poll() on /dev/rtc. I used this to pulse a hardware register in a project I did a few years ago, worked good enough for my purposes. You might lose an RTC interrupt here and there if your system is under heavy load (call it "soft realtime"), but I think the interface tells you if and how many you lost. There's also the more advanced HPET timer available for newer x86 systems, but I haven't looked at that yet. Good luck, -Jamie Guinan

SSH Tunneling?
by Michael Zarozinski 24 Jan '06

24 Jan '06

Hi all, I'm in the process of moving a web site, msql db, and some game daemons to a new server. While the DNS transfer is in process we want all traffic to go to the new server. I've been told this can be done vial ssh tunnels but don't have any experience.... can anyone point me in the right direction? Do I need to set up a tunnel for every port on the old server (the games open ports)? How is it set up to run all the time? Do I need to mess with sshd_config? Any and all help is appreciated! Thanx!

Rough upgrade to FC4
by Bill Mills-Curran 23 Jan '06

23 Jan '06

I just upgraded to FC4 from FC3 and I had some troubles that should not have happened. My FC3 system was current with updates, and I used downloaded ISO's from fedora. The problem was that many of the FC3 packages were more up to date than the FC4 packages, so the upgrade did not install them. This included the kernel. I felt lucky that I had a workable system. Running up2date did not help -- I was still in an FC3 system (kind of). I manually installed the FC4 kernel and ran up2date again, but it was stuck on many packages, because up2date only wanted to freshen existing rpm's -- it didn't want to add any new ones to solve dependencies. After much arm-wrestling (floundering?), I gave up on the GUI up2date and ran with the command line, feeding it chunks of rpms that needed updating. I feel lucky that I didn't brick my system. What did I do wrong? This must be a common occurance. I have another system that I need to upgrade, but I don't want it to go like this. What's a better way? Thanks, Bill

I had partitions setup the following way /boot / swap /home /usr/local/ This way I can keep the users data and just install a new system over it. I think that Debian's method of package management is the best of any of the Linux Distro's. I a year ago I switched from FC3 to Ubuntu because Ubuntu has a 6 month release cycle, similar to FC and Ubuntu pays individuals to fix security vulnerabilities. --Josh > I drifted from RH to Mandrake (pre-Mandriva) and then to Gentoo. > Though not without the occasional bump, I've found Gentoo's approach to > package management the least violent of them all. > > Nathan > > > > > Running up2date did not help -- I was still in an FC3 system (kind of). > > > > I manually installed the FC4 kernel and ran up2date again, but it was > > stuck on many packages, because up2date only wanted to freshen > > existing rpm's -- it didn't want to add any new ones to solve > > dependencies. > > > > After much arm-wrestling (floundering?), I gave up on the GUI up2date > > and ran with the command line, feeding it chunks of rpms that needed > > updating. > > > > I feel lucky that I didn't brick my system.

Perl Unicode question
by Skip Gaede 22 Jan '06

22 Jan '06

Folks, I'm trying to understand how Unicode works in Perl 5.8.7, and things are not working the way they're described in perluniintro. In particular, I have a file encoded in UTF-8 from Perl, that I want to convert to Windows Unicode (UCS-16LE). The intro provides this snippet for converting from one character set to another: open(my $nihongo, '<:encoding(iso2022-jp)', 'text.jis'); open(my $unicode, '>:utf8', 'text.utf8'); while (<$nihongo>) { print $unicode } When I try that, substituting UTF-8 and ':encoding(UTF-16LE)', I get no warnings, but the output has twice as many characters as it should have and they are all NULLs. I can supply a my UTF-8 file if anyone wants to have a try. In particular, I think the fact that I have embedded apostrophes (0x27) encoded as RIGHT SINGLE QUOTATION MARK (0x2019) may be part of the problem. Thanks, Skip

Trial By Fire
by Marie MacDonald 21 Jan '06

21 Jan '06

Greetings All! You may recall a while back I was asking questions about Linux laptops and video capture and editing software for Linux As luck would have it, I was given a shiny new (well, slightly used) Linux desktop compuer. It is running the Novell distro (see I'm learning!!) and I'm loving it. As fate would have it, my laptop died two days ago and this Linux system is all I have left. I no longer have the luxury of time to fiddle and learn. I am working my way through that Novell Linux Desktop free online training, but for some reason that's not allowing me to log in. That's not my question though. No matter how hard I try, I can't install software. I have read the manual and I know how to log in to the root system and activate YaST. I was trying to install Thunderbird 1.5. But I'm enjoying using Evolution, so perhaps I'll forgo Thunderbird for now. I just could not get YaST to recognize or "see" the Thunderbird package. I even figured out "change source of installation", all to no avail. Do downloadable software packages for Linux come with intallers? Can anyone help with advice for YaSt? Is my issue with the Thunderbird 1.5 package perhaps? Quite frankly if it's this hard (frustrating!) to install software, I'm not gonna be a happy gal. I still have other things I want to add to this snappy little computer (i.e. my Palm) but darn there's gotta be an easier way. Spring semester starts 26 January and I need this up and running. Thanks for any advice, support, shoulders to cry on Marie mimsresearch(a)gmail.com
