New Printer suggestions request
by Mel Seder 22 Aug '02

22 Aug '02

I run Red Hat 7.3 and Windows 98 I don't do too much text printing but have a digital camera and do print pics on Glossy Photo Paper both 8.5 x 11 and 4 x 6 sizes. I expect to pay between $300 and $400 for a decent printer. Please share your knowledge or experience with me :-) ===== "The sooner you make five thousand mistakes, the sooner you will be able to correct them." - Kimon Nicolaides __________________________________________________ Do You Yahoo!?

At least as far back as Red Hat 7.1, when they tightened security and allowed you to configure ipchains-based firewalling right from the installer, many of the network services started through xinetd, and particularly those with security issues (like telnet, ftp, rlogin, rsh, and rexec) are no longer enabled by default. The ssh service (based on the OpenSSH implementation) is enabled by default, and is what they recommend you use instead of the alternatives. The "Connection refused" message above suggests that the service is disabled. If you aren't concerned about the security implications of enabling telnet, you can do it as follows for Red Hat Linux: chkconfig telnet on The chkconfig command is a convenient way to enable and disable init- and xinetd-based services. You can see what's enabled and what isn't as follows: chkconfig --list There's also the "ntsysv" command, which is a text-based GUI front end to this. It will present you with a merged list of both init- and xinetd-based services as a scrollable list, and allow you to select or deselect those to be enabled for the default set of run levels. It's not as flexible as chkconfig, but it is easier to use. -- Gilbert E.

telnet question
by millward 21 Aug '02

21 Aug '02

I managed to get NFS working between one machine with Red Hat 7.3 (server) and another machine with Slackware 6.3 kernel 2.0.35 That is, it works when the server is not root. But what really puzzels me is telnet. I can ping from both machines with no trouble, but telnet only works when the server telnet's the client . Telnet fails when the Slackware machine trys to telnet the Red Hat machine. e.g. telnet 194.155.75.90 telnet: Unable to connect to remote host: Connection refused Is the Slackware 6.3 kernel 2.0.35 telnet version just too old? Or is something in Red Hat keeping it from connecting? Security is not an issue here. This is just two home machines.

I don't know that to be true in any of the newer systems, but it may have been the case with some of the earlier BIOSes. Many of them didn't implement the CD-ROM booting feature in a fully standard way, so there could be such limitations with some systems. I'd try it and see. In your case, it may be best to leave it as the primary slave, and make each of your two hard drives masters on each of the two IDE controllers. > I plan to spread one Linux installation over > both hard drives.

Linux uses device names based on the (fixed) hardware configuration for IDE devices, as follows: hda primary master hdb primary slave hdc secondary master hdd secondary slave ... So, removing a slave device wouldn't affect anything. If you removed a master device, you might have to turn it's corresponding slave into a master, which would change names. However, there isn't much in Linux that depends on these hardcoded names anymore. You might have to fix /etc/fstab, and either /etc/lilo.conf or /boot/grub/grub.conf, depending on your loader. But, if you make your CD-ROM drive a slave (primary or secondary), you should be able to remove it without changing anything. Spreading your two hard drives across the primary and secondary controllers (as masters) will give you a slight performance advantage over having them both on one controller (as master and slave), since the two controllers and drives can then overlap I/O operations. The CD-ROM drive would slow down disk I/O on the controller it's tied to, but if you'll be removing it later, that would be fine. -- Gilbert E.

2 HDs and a CD-rom
by millward 17 Aug '02

17 Aug '02

I was wondering, is there an ideal way to configure a system with two IDE hard drives and a generic read-only CD-rom ? I read somewhere that the CD-rom had to be a primary slave for it to boot properly. Is this true? I plan to spread one Linux installation over both hard drives. Its a P133 and the hard drives are both 540 megs. And one more question. The CD-rom in the system above is really just for installing Linux. After that I plan on removing it. Would removing the CD-rom 'confuse' Linux and screw things up or will the boot up proceedure recognize the new configuration?

command line question, cat and dd

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 09 Aug '02

09 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 ?
