How to set "-dpi 100" for X with kdm
by Andy Stewart July 19, 2002

July 19, 2002

HI all, When I start my SuSE 8.0 system in run level 3, it comes up in textmode. I log in and issue the startx command and KDE comes up. In my ~/.xserverrc file, I have put "-dpi 100" and the X server comes up in 100 dpi mode and I am a happy camper. Now, I think I'd like to have the graphical login from run level 5. kdm comes up with a nice screen, but the X server is only running at 75 dpi. I cannot figure out where to put the 100 dpi setting for this situation. It appears not to read the same files for the xdm/kdm method of starting the X server as it does when one types startx. So, how do I properly setup 100 dpi for kdm/xdm? Later, Andy -- Andy Stewart, Founder Worcester Linux Users' Group Worcester, MA USA http://www.wlug.org

This program will work with a file, and a floppy device, but not a tape device. can anyone give me some pointers? what do i have to do differently to write to tape? Thanks, --brad

Question about WLUG BBQ
by Andy Stewart July 19, 2002

July 19, 2002

Hi WLUG, We had a suggestion last night over a few beers that perhaps we could conduct our next Linux meeting in Shrewsbury over a few BBQd burgers, dogs, etc. What do people think of that idea? If this idea is accepted by enough folks, it would be held on the same day and time as our next regularly scheduled meeting. What do folks think of this proposal?

Thanks!
by Tim Trachimowicz July 18, 2002

July 18, 2002

Hey folks! Thanks for multiple answers to my question. I ended up using Theo's solution: for i in *_x.*; do mv -f $i `echo $i | sed -e 's/_x././'`; done and it worked perfectly to get the job done. I've since been playing around with a few of the other suggestions to see what would work best next time I need to do soemthing similar. If anything, it's sparked my interest to learn more about shell scripting. Thanks again! --Tim

Bash help
by Tim Trachimowicz July 18, 2002

July 18, 2002

Hey folks! I have a bunch of files on a server that are in the format "filename_x.dat" and I need to rename them "filename.dat", i.e. strip to last two characters off the filename while maintaining the extension. If it wasn't for the fact that I have about 400 files in multiple directories, I'd do it by hand. However, it's of a somewhat urgent nature - hence this slightly off-topic cry for help! =) I'm pretty sure there's a way to do it via a shell script (I use bash) - the only problem being that I've never written one before. Can anyone point me to a faq/tutorial/website that might explain the process? If it's a trivial task, anyone care to take a stab? Google gave me a few leads, but most aren't helping a lot. Any help is appreciated! Thanks! --Tim

HI everybody, This month's WLUG meeting will be held on Wednesday, July 17th in Kinnicutt Hall on the WPI campus at 7:00 PM. The topic will be "Wireless Networking" and I'm pretty sure we have a speaker. If you have a laptop with a wireless connection, bring it along. I'll bring my new Linksys access point (WAP11) and my laptop. Bring whatever you think will make this an interesting meeting! After the meeting, we'll make a trip to the Boynton Restaurant for pizza and beer. I hope to see you there!

interesting problem
by Wesley Allen July 16, 2002

July 16, 2002

Shortly after I started using a wireless lan, I began having problems with connecting to my local ip addresses; I'm not sure what's causing it. Internet works FINE, and yet, a couple of minutes after I boot my machine I can't connect to anything in the 192.168 range! It doesn't matter the protocol, smb, http, etc. no connections at all. What's stranger is that my win4lin install, which uses vnet, has no problems at all. What in the world is going on here? Any thoughts? Wes

Lexmark z22 printing
by Bill Smith July 15, 2002

July 15, 2002

Printing fun... Some of you might already know what I have to say, but I wanted to get this out for those that are in my boat... I am running a Gateway Solo 9100 laptop with Red Hat 7.3 installed. I mentioned a few months back (almost a year ago, now) that I had gotten my Lexmark z22 to print with Red Hat 7.1. One thing that I hate about upgrading RH versions is that it invariably forces me to re-learn things, since Red Hat can't seem to leave current configurations alone. 8\ ANYWAY, for a bunch of Stupid Reasons, I decided that I wanted to make use of the USB port on my z22 instead of the parallel port. Imagine, if you will, the fun I had in trying to get a printer that is barely supported by Linux to be recognized on the USB interface... I went to Lexmark's website and got the Linux drivers. Wouldn't you know it, though, but the drivers make no effort whatsoever to support the USB interface on the printer! After a bit of poking around, I realized that there was a KDE Control Panel! I use Window Maker by default and I was annoyed that control-panel was removed. I went through there and LO! the Lexmark z22 is there, right on the USB interface! 8) Granted, there are a couple snags. It looks like I can print multiple text-only documents with no problem, but if I print a Postscript file, then I have to turn the printer off then turn it on again. Compared to having no printer at all (or worse-yet, having to print from WinDOZE!), I see this as only a minor inconvenience. I'm thinking that this rig is using the foomatic configuration scripts, which may be unacceptable to some. I base this thought on the fact that the driver in use is actually for the Lexmark 3200 series, which (according to the .xml file) may print "a bit too rich"... <shrug> It looks okay for the black text that I'm printing with right now. I just wanted to share what I came across. Any corrections/suggestions are appreciated. (Yes, I went to http://www.linuxprinting.org ...)

Konqueror enhanced browsing
by Andy Stewart July 14, 2002

July 14, 2002

Hi all, I've noticed in Konqueror that one can type things like: info: ...in the URL field and Konqueror will display info pages. There are others, such as: smb: lan: ftp: man: http: camera: The aforementioned are not listed in the Konqueror enhanced browsing configuration window, and I would guess that they are Konqueror defaults. Is there a definitive list of these? I'm wondering what features I might be missing that I'd like to use!

tmpfs
by Bill Mills-Curran July 2, 2002

July 2, 2002

When researching the Reiserfs a while back, I discovered the tmpfs file system and the --bind option to mount. Both of these are nice tools to have around. --bind has made it into the mount man page, but the tmpfs is not documented in the man pages anywhere I can think to look. Does anyone know of a reason that it should not be used? I'm thinking of using it for some locking files and pid stamps -- all stuff that should not persist across a reboot. TIA, Bill

hardware problem?
by avedis＠ma.ultranet.com July 1, 2002

July 1, 2002

I just had trouble booting into linux. Tried several times, but kept getting a blank screen, so I booted windoze. I noticed that I saw nothing on the screen until I got to my windows desktop, so I tried booting to linux again, and waited for my hard drive light to stop. Then I logged in with a blank screen, called up X, and it came up fine. Any ideas why my startup screen is missing? I haven't tried going into my bios yet, to see if it comes up on the screen. I'm not sure I remember how to get out of the bios on this machine, so I'm a little hesitant to go there. I'm not sure how to proceed, so any ideas are welcome.

What are Lindows and Lycoris?
by Andy Stewart June 28, 2002

June 28, 2002

HI all, Walmart is selling ultra-cheap PCs with Lindows on them (the PC is by Microtel). The screen shots look alot like KDE. Lindows makes software available for download on their website (the apps, not the OS) for a fee. I've also seen Lycoris, and on their website, they make passing references to Redmond Linux. So, I ask the question, are these just some version of Linux "packaged for the masses"? If not, what are they? Are there other similar products besides Lindows and Lycoris?

Lilo :-)
by doug waud June 27, 2002

June 27, 2002

Hi all On the TV lately I have heard a lot about Lilo. It seems to be in the context of something called Stitch. I am not clear on the details but Stitch apparently is some sort of extraterrestial with a bent to destroying everything it encounters. I assume the reference is, therefore, to Microsoft. The interesting thing about Lilo is that it never seems to be spelled LILO. The first letter is captialized so I assume there is some degree of case sensitivity involved. If any of you can decipher what all of this means perhaps you could fill me in! :-) I do notice that Disney seems to be involved so it would seem that Pixar is not the only place Linux seems to be making inroads. doug

Thank you all for your help.... just wanted to let you know the outcome of the installs... On the HP Vectra, there appears to be some hardware issues, as Windows 2K boot floppy fails with a Boot I/O Error. This machine has been suspect, and I will probably scavenge it for parts (CD, Memory) (It has had some intermittent problems finding the HDD.) On the HP Kayak..... it's UP! I downloaded the new boot disk image from the email below, and the install ran without a hitch. It must not like the 7.2 standard boot image since it failed both from the install disk and from the boot floppy I made straight from the CDROM. (This was a CD burned from the WLUG installfest in February and it has installed faithfully on about a dozen machines.) Thank you again. jeff -----Original Message----- From: Charles R.

It depends. Does the signal 11 always happen at exactly the same point? If so, that doesn't necessarily point to flakey hardware, but rather a software bug.

You can test your RAM with memtest86, available here: http://www.memtest86.com/ Another thing you can try is making sure the amount of memory is detected correctly by Linux (check the boot up messages of the Linux kernel). If not, you can force the correct amount by appending the mem option to the linux boot command line: linux updates mem=56M You need the "updates" bit to use the update-disk mentioned earlier.

Hi again, Over the weekend, I received some "creative" feedback and all of it is appreciated. Why question was intended to find an easy way to track down the owner of an IP address within our corporate network (unregistered with DNS/WINS). Not to hack, crack, spam, or DOS them, but to gain information on that particular node. I have to bring this IP address to the attention of our Security Team, but wanted more information to give them.

fsck, segmantation fault, etc.
by Baris Hasdemir June 24, 2002

June 24, 2002

Hi, I bought a new hard drive, Maxtor 7200 RPM, ATA133, 40GB, and began using it at ATA100. I formatted my /dev/hda5 with mkfs.ext2 and mounted it under /home. I have been using this mount with the Slackware 8.0 at /dev/hda6 for several days without any problems. Two days ago I installed Slackware8.1 on /dev/hda8 and used the same device mounted to /home. (/dev/hda5) Yesterday under root privileges I attempted to delete a user's two big files, and got the following error (or warning, I don't know): root@penguen:/home/avci# rm more_than_700MB_files* EXT2-fs error (device ide0(3,5)): ext2_free_blocks: Freeing blocks not in datazone - block = 1083636778, count = 1 EXT2-fs error (device ide0(3,5)): ext2_free_blocks: Freeing blocks not in datazone - block = 1083606420, count = 1 EXT2-fs error (device ide0(3,5)): ext2_free_blocks: Freeing blocks not in datazone - block = 1083602068, count = 1 EXT2-fs error (device ide0(3,5)): ext2_free_blocks: Freeing blocks not in datazone - block = 1083602292, count = 1 root@penguen:/home/avci# ls -al total 24 drwx--x--x 2 avci misafir 4096 Jun 23 12:47 ./ drwxr-xr-x 10 root root 4096 Feb 25 2001 ../ -rw------- 1 avci misafir 36 Jun 17 17:26 .bash_history -rw-r--r-- 1 avci misafir 34 Jun 17 16:44 .less -rw-r--r-- 1 avci misafir 114 Jun 17 16:44 .lessrc -rw-r--r-- 1 avci misafir 3394 Jun 17 16:44 .screenrc However, rm deleted the files. But I couldn't understand the warning. And then, just because of curiosity I tried to copy one of the same big files from another partition to the same location, and cp gave out those: root@penguen:/home/avci# time cp /mnt/hda10/one_of_the_big_files .

It might give an idea if I mount it like this #mount /dev/hda5 /home file names appear as $@#$#%#$ etc. but if I mount it like that #mount /dev/hda5 /home -t ext2 no problem seem to occur. I am thinking about whether I did something missing at the fdisk stage or formatting stage. Or is my new hard disk a dead-born? Or any other things you may notice? thank you, baris

Who is port scanning me?
by Simoncini, Matthew June 24, 2002

Hi everyone, I'm constantly getting port scanned from a certain IP address on our internal corporate network. I'd really like to find out where and who this person is, but don't know much outside of ping, traceroute, nslookup, etc .... I was wondering if anyone knows of any tools that can get me more information on this person? This happens to be on our private network, so most internet tools I don't think will help much. Thanks for your time. Matthew
