Growing pains would be my guess. Agere was spun off from Lucent a couple of years ago, and the ORiNOCO product line is split - Lucent has the Access Points and Gateways, while Agere handles the RF cards and other microelectronics. I hope they get their act together soon, as the products are great!

Make sure you set all the passwords to never expire for all the users on all of the machines.

I had this problem with my housemate's PC. I initially created a useraccount for him on my PC, and one for me on his, using the same passwords as we use on our own machines. The problem was that these accounts expired on each other's machines. We both got notified to change our own local passwords, but the mirrored accounts just got left in limbo, meaning shares stopped working

Good advice! Supposedly the ORiNOCO gateway is a DHCP server, too, so I shouldn't have to dink around with the TCP/IP settings. Smile | :)

MTU & TTL

Hello everyone...

I got a question no one seems to know the answer in the place I am working in.When I send a ping to a machine X ,I got TTL = 128 , and after I optimized the machine X and I "ping" it again I got TTL = 56.

I know for sure that this machine X is connected to the internet through ADSL , and I am pinging it from a local network.I also know the machine X could have any of the MS system , but definetly not Linux or Mac OS.

I don t understand how the packet size (MTU) could affect the number of router it goes through (TTL) , so please help me with it ..

Confused | :confused:

Thanx

TTL field is set on the originating machine, so changing MTU on another machine, has nothing to do with changing the TTL value on the originating machine.

Sounds a bit strange, that you've optimised machine X, but don't know for sure what OS it is running!

Ok...

I rephrase my question so I ll get better answer than this one...

Some friend told me he got Windows XP connected to the net with ADSL.He also tell me his I.P. address , and ask me to ping his machine and tell him what I got.I noticed I got a TTL value of 237 ...(My friend was interested in the request time in ms and not the TTL I got)
The next morning , the same friend ask me again to ping his machine , and then I am suddenly suprised to see his TTL changed to 56 !
So I asked him what is going on ?
And I get for answer :"I install a reg patch from "speedguide.net" to optimized my machine , to change its MTU".

Is it possible that changing the size of a packet can actually change the time it's travelling through routers ?

Wise answers only , please..
Cool | :cool:

How do you mean wise ?

Your question was a bit stupid really. You said that you have optimised a machine and don't know what OS is it running on !!!!

Upgrading home WinXP to professional WinXP

4-Aug-02 6:50

Event Viewer doesn't keep a database of Event IDs that are associated with an error message. It's up to the application that generates errors, to regitster Event ID's and associated error messages.

Error ID 27 could mean anything. This is relative to the application itself, not the actual Event Viewer.

Usually whenever an error ID is not registred, Event Viewer will give you some more information about the error itself and usually the app. return code.

I suggest look at that string again and see what app. is generating it.

Regards,
Venet.

If I leave my XP (professional version) alone for a few hours, the HELPSVC and SVCHOST processes start up and start eating megabytes of RAM (500MB+). How do I stop this? What's going on in the background?

It doesn't seem like XP is a very stable platform for long-term usage, like a server app. Should I be using W2000 server instead?

Thanks,
Marc

Have you reviewed your Event Viewer?

Could be that some service is failing and svchost trying to start it up again over and over.

Thank you for the suggestion. The problem appears to coincide with this message:

"The COM+ Event System detected a corrupt IEventSubscription object. The COM+ Event System has removed object ID {71EDA56F-317A-11D2-98A9-00C04F8EE1C4}-{41E90F3E-56C1-4633-81C3-6E8BAC8BDD70}-{00000000-0000-0000-0000-000000000000}. The subscriber will no longer be notified when the event occurs."

Any ideas? I'll have to root around now that you've given me a clue.

Thanks again,
Marc

Okay, I got over the LILO problem in my last post, but I've got another problem. The genius that is the Windows installer has made C: my system partition and D: my boot partition. I need to make C: my boot partition as well (cuz D is beyond the 1024 cylinder limit of LILO). How do I do this? Simply copying ntldr and company doesn't work.

Thanks.

Venet28-Jul-02 5:38

28-Jul-02 5:38

Ok first of all, it's a bad idea installing LILO on your MBR, as I'm sure you've found out yourself. Smile | :)

sultan_of_6string wrote:

You can have only one boot partition, can't have more. To make a partition bootable, use fdsik. Make a Win9x boot floppy and copy fdisk.exe in there. Start your machine from the disks and run fdisk. It will give you the option of making a partiton bootable.

The best (that is, safest) way to go, is to install LILO on secondary partition and copy the first 512 bytes of the second partiton to the first one. Add an entry to boot.ini file to point to this new file of 512 bytes.

And that's it.... Wink | ;)

Venet.

Thanks for the response. You seem to know about this so could you help me out here?

I've read about this stuff of copying the first 512 bytes, but it doesn't seem to make sense. Won't it corrupt my NTFS partition? If you could give me a few points or link me to a decent article, it would be great.

Plus, I got the strange feeling I'm posting on the wrong website... any suggestions?

Thanks.

Nope, it won't. You are copying 512 bytes of secondary partition.

To do this:

boot up in linux. If you're running X-Windows open console (as root) and type

dd if=/dev/hda2 of=/tmp/bootsect.lnx bs=512 count=1
(provided /dev/hda2 is your linux partiton, if you have separate hard disk, it might be /dev/hdb1)

This will copy the boot sector of the linux partition.

Now, copy this file onto a floppy disk

Provided that floppy disk is mounted in /mnt/floppy execute the following

cp /tmp/bootsect.lnx /mnt/floppy or

mount -t vfat /dev/fd0 /mnt/floppy
if floppy is not mounted.
(in here make sure /mnt/floppy directory exists)

Boot in WinXP

Copy bootsect.lnx from floppy to the C:\

Open boot.ini file.

It should look something like:
-----------------------------
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Windows 2000 Professional"
-------------------------------

Add this line to the end of boot.ini

C:\BOOTSECT.LNX="Linux Rocks"

Save and Close.

That's it, reboot your WinXP and there ya go. Smile | :)

Note: This assumes that you've installed lilo on your secondary partition. For how to do that, you might want to read lilo man page.

Smile | :)

Venet.

Thanks a lot. I tried that, but whenever I try to boot to RHL, the system restarts. My config is a little wierd:

Partition 1: Drive C NTFS--System
Partition 2: Linux /boot
Partition 3: Linux root (beyond LILOs 1,024 cylinder limit)
Partition 4: Linux Swap
Partition 5: Drive E NTFS--Boot (don't ask why, I can't figure it out)

So, I installed LILO to the /boot partition and used dd, but it didn't work.

Argh! Why must NT hijack my MBR?!

Venet29-Jul-02 1:02

29-Jul-02 1:02

Ok try this command

lilo -s ./bootsect.lnx

It should do the same thing as in my previous post.

sultan_of_6string wrote:

Can you get into Linux at all ?

You might want to try booting from the Linux CD, if you haven't created any bootable floppies and then execute the above command.

Let me know how you get on. Smile | :)

Venet.

Thanks a lot for the reply, but I'm gonna have to wait a bit. I tried a third-party bootloader (Bootmagic or something) and it fried my MBR. XP refused to load and RHL simply restarted my system. RHL setup said that my disk geometry is messed up. Didn't know what that meant but it didn't sound good. Well, now I'm back to Win98 Frown | :(

and my parents aren't too keen on Linux, so I'll just put XP on this machine and try out Linux again in college. A few days was enough to get me super-excited about projects like Gnome and Mono. Programmer's paradise! Smile | :)
