command line question, cat and dd
by millward 12 Aug '02

Subject: forgot the '>' in cat command. Excuse: I was just following the example given in the Linux Terminal Server doc, ltsp-3.0.pdf ! But that is a rather lame excuse. I should have known better. Thanks for the help.

command line question, cat and dd
by millward 08 Aug '02

08 Aug '02

I'm trying to write the file eb-5.0.7-via-rhine.lzdsk to a floppy diskette in /dev/fd0. When I did the following command: cat /home/ed/eb-5.0.7-via-rhine.lzdsk /dev/fd0 the screen filled with zeros and wierd characters and stayed that way after the command supposedly had finished writting the file to the floppy. I had to boot <Ctrl> <Alt> <Delete> since the keyboard was useless. No harm done. Everything seems OK after the boot. Using another floppy, I tried: dd if=/home/ed/eb-5.0.7-via-rhine.lzdsk of=/dev/fd0 obs=18k No problems with dd. The copy seemed to work quicker. My question is, are the two commands, dd and cat, equivalent for writting data to a floppy? And why did cat screw up my keyboard?

KGostView no print PDF RH 7.3
by millward 08 Aug '02

08 Aug '02

I'm running Red Hat 7.3. The KDE KGostView pdf viewer won't print pdf files. It gives the message: "The file format application/x-zerosize is not directly supported by the current system." KGostView asks: "KDE convert this file to application/postscript ?" So I agree, but it fails and says: "no appropriate filter" My printer is an Epson 640 which I loath but can't afford to replace. RH 7.3 with KDE prints text OK. I've even printed a couple of HTML pages using Konqueror.. Anyone know how I can get KGostView to print PDF? The problem is not the printer. My system is multi-boot so I booted into Slackware 7.1 Gnome and used the Gnome Ghostview 0.95 to print the PDF file, no problem. But I don't really like Gnome and KGostView should do the job in Red Hat 7.3. What have I failed to do in Red Hat 7.3 ?

RealOne Player
by Mel Seder 05 Aug '02

I had to go to Windows 98 to listen to a live "the other ones" concert. The second show played tonight. The first show was played live at Alpine Valley Music Theatre, just outside Milwaukee, last night. The band is who the grateful dead used to be minus Jerry. After the internet broadcast I started playing around with the RealOne media player and found the games section. What a nice experience that RealOne was. I hope RealOne gets ported to Linux so that it will run on Red Hat Valhalla 7.3. ===== "The sooner you make five thousand mistakes, the sooner you will be able to correct them." - Kimon Nicolaides __________________________________________________ Do You Yahoo!?

UPS
by Brock Wolfe 02 Aug '02

02 Aug '02

Well its time to get out of the procrastination easychair and upgrade my UPS. I've used APC 500 and 625 VA UPS's on various PC's in the past. However these UPS don't seem to last, with electronics and batteries failing. I am looking to replace the smalller individual units with a single larger unit around 3000VA to support a server/network cluster. While batteries can't be expected to last forever, I am looking to improve the lifetime and reduce long term costs of providing UPS. The current individual UPS's will be be spun out to cover less critical PC's. Anyone with suggestions, testimonials, or works of advice on larger UPS installations. Or does this plan have an achillies heel? Brock Wolfe ___________________________________________________________ "The problem is not that there are problems.

I am looking at using ReiserFS on a RedHat Linux 7.3 installation as a data drive. Can anyone give me some info on the stability of this fs? Opinions on whether it is better/as good as ext3? Thanks.

Writing backups to Pioneer DVR-A04 DVD-RW writer.

Hello all, Here's one I can't figure out. Downloaded cdrtools-1.11.dvd.tar.gz, and compiled. Nice and clean worked like a champ. Wrote about 70 megs to the drive. Worked great. Here's the rub. I've got a 4.7 gig RW disk in the drive, and I'm trying to write 2.7 gigs or so of data. My output's below. Am I doing something wrong here? It says the data won't fit on the disk. Huh?

Is there anything funny about the files in question? Do you have permissions on them? Are they regular files or special devices?
