hardware problem?
by avedis＠ma.ultranet.com 01 Jul '02

01 Jul '02

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. Athlon 1.2G, Spacewalker AK12A motherboard, ELSA GLoria L vid card, Viewsonic A70 monitor, 256RAM. I've got another computer here, so I could try switching monitors (not tonight). Thanks. Greg

spam attack

I just received some porn spam that has wlug address as the return address. Should I just ignore and delete, forward to spamcop, or does someone here want to deal with the spammer personally? Looks like it came from 194.143.190.11. This shit should be illegal. Awaiting further instructions... Greg

What are Lindows and Lycoris?
by Andy Stewart 28 Jun '02

28 Jun '02

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? Thanks, Andy -- Andy Stewart, Founder Worcester Linux Users' Group Worcester, MA USA http://www.wlug.org

Lilo :-)
by doug waud 27 Jun '02

27 Jun '02

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

RE: [Wlug] Installing Redhat on HP machines
by Hemstreet, Jeffrey 26 Jun '02

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. If it IS random, then it does sound like a memory error. 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. Insert the updates disk when it asks. jhemstreet> The other is a dual-300 PII HP Kayak with a SCSI Drive.

Bad floppy disk and/or CD-ROM? How did you acquire your Red Hat 7.2 CD-ROM? If it isn't an official disk, then it might have been burned incorrectly. Red Hat recommends burning ISO's in Disk-At-Once mode, and checking the images and disks with md5sum to be sure they burned correctly. -- Charles R.

Installing Redhat on HP machines
by Hemstreet, Jeffrey 26 Jun '02

26 Jun '02

I am having a problem installing Redhat 7.2 on 2 different HP machines. I thought I might be able to get some information from the plethera of people who have done installs. Or any ideas on what to do next? One is an HP Vectra (2Gb IDE, 56MB, P200). I can fdisk and select packages, but when it goes to format the disk to install the packages, I get a signal 11 fatal error. I think there may be something flaky with this system (HDD or memory problem?) Just wondering if anyone else has seen this type of failure and could give me any more insight. I plan on replacing the HDD to see if that is the problem. The other is a dual-300 PII HP Kayak with a SCSI Drive. I get a boot error when trying to boot from the CDROM or Install Disk. This system is currently running NT 5. Any ideas why the boot would fail? Thanks, jeff

RE: [Wlug] Who is port scanning me?

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. Given all the feedback, it seems easier just to contact the Security Team and let them figure this out. Thanks again for your time.

Chances are the machine that is performing the portscan is hacked himself. It does no good to "hack them back" because your not hacking the hackers...your hacking the hack. :-) On top of that, you'll only cloud the issue and, if the matter is taken to the authorities, you could also get in trouble. Not to mention the entire concept of hacking without authorization is unethical and illegal. I'm going to go say its not worth it. This does happen constantly if your connected to the Internet. Your best offense is a good defense.

fsck, segmantation fault, etc.
by Baris Hasdemir 24 Jun '02

24 Jun '02

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 . Unable to handle kernel NULL pointer dereference at virtual address 00000004 *pde = 00000000 Oops: 0002 CPU: 0 EIP: 0010:[<c0128240>] Tainted: P EFLAGS: 00010046 eax: cbf58000 ebx: 00000003 ecx: ca000000 edx: 00000000 esi: c1405e50 edi: 00000202 ebp: c12f1f80 esp: c14e7efc ds: 0018 es: 0018 ss: 0018 Process kswapd (pid: 4, stackpage=c14e7000) Stack: ca000240 cbe9b8c0 cbe9bb40 c12f1f80 c0130f12 c1405e50 ca000240 c0132a9c ca000240 ca000240 c12f1f80 000001d0 00000009 00000200 c013118c c12f1f80 000001d0 cbe9bb40 c12f1f80 c0128f62 c12f1f80 000001d0 00000020 000001d0 Call Trace: [<c0130f12>] [<c0132a9c>] [<c013118c>] [<c0128f62>] [<c01291a6>] [<c012921c>] [<c01292b3>] [<c0129316>] [<c012942d>] [<c0105708>] Code: 89 42 04 89 10 8b 46 08 89 48 04 89 01 8d 56 08 89 51 04 89 real 0m54.986s user 0m0.060s sys 0m7.330s And then of course I did a couple of fsck on this partition after unmounting. first one quitted after several error correcting, second fsck did segmentation fault but the last one did finish fsck. and lots of error were corrected. 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 24 Jun '02

24 Jun '02

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
