<DIV>We are running some file transfer experiments using FTP/TCP/IP/PPP between two Linux PCs (running Red-Hat Linux 7.3 with kernel 2.4.18-3). We are trying to change the PPP MTU size (using "ifconfig ppp0 mtu xxx"). The situation is described below: (1) When we change the MTU to a size which is smaller than the default size 1500 bytes, it works using the new size, which can be observed from SYN, SYN-ACK exchange and TSG plots. (2) When we change the MTU to a size larger than the default 1500 bytes (such as 4352 bytes), the protocol still sends data using the default size of 1500 instead of the updated larger size. I think the problem is that segments/packets delivered to PPP are limited to less than or equal to 1500 bytes. So even though we enlarged PPP MTU, the PDU delivered to PPP by TCP/IP is not larger than 1500 bytes. Could anyone advise us how we can adjust the size of TCP/IP segme! nts larger than the default size of 1500 bytes so that the transmitted PPP frame size is larger? Any help will be greatly appreciated. redhat-list-request@redhat.com wrote: <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">Send redhat-list mailing list submissions to redhat-list@redhat.com To subscribe or unsubscribe via the World Wide Web, visit https://www.redhat.com/mailman/listinfo/redhat-list or, via email, send a message with subject or body 'help' to redhat-list-request@redhat.com You can reach the person managing the list at redhat-list-owner@redhat.com When replying, please edit your Subject line so it is more specific than "Re: Contents of redhat-list digest..."

It's not too hard to get grub reinstalled to your satisfaction, but I don't have a step-by-step procedure handy. BTW, on my dual-boot machines, I tend to like to install grub in the boot record! for the /boot partition and set /boot active with fdisk. That avoids the problem of having Windows overwriting it every reinstall. After reinstalling Windows, one just needs to run fdisk and set /boot active again to have grub work. > > > Sachin > > ________________________________ > > From: Billy Davis [mailto:bdavis@cds-corp.com] > Sent: Mon 4/12/2004 11:36 AM > To: redhat-list@redhat.com > Subject: RH 9 dual boot problem > > > > I am trying to set up a dual boot RH 9 workstation.

If you post an answer above a q! uestion, people have to read bottom-to-top which is a pain in the ass.

Is there an easy way to restore >the RH boot record back into the MBR, other than reloading >RH again?? You are correct, Windows overwrites the MBR without asking. Sorry I do not have the time right now to provide a detailed answer, but at least a general guide: 1. Boot from the Red Hat Linux CD's with "linux rescue" at the boot prompt. Once the rescue disk functionality boots up, you will be able to access your normal Linux partitions by mounting them (I believe you can find them in /mnt/sysimage). 2. Mount the /boot partition, or the / partition if you do not have one. 3. Run "grub-install /dev/hda" (assuming hda is the right drive, of course). Done. Please search the Red Hat site or Google for better, more detailed instructions than this... I am in a hurry and there may be something wrong there. Search for "reinstall grub" or something like that. But it *is* an easy process, with no tweaking or kernel hacking necessary. Cheers, -- Rodolfo J.

Is! there an easy way to restore the RH boot record back into the MBR, other than reloading RH again?? Thanks BDavis Actually, it is easier than all that. Take a look at the man page on grub-install. This replaces the Windows boot track with the grub boot track. grub will then read the /boot/grub.conf file to find all its pieces. Tom Thomas S.

I have used the Internet Configu! ration Wizard to set up the modem, when I click on "activate" it says "failed to activate ppp0 with error 8. But I see light flashing on the modem. I have also set up kppp and when I click on connect it says "modem ready" (I see lights flashing on the modem), then it says "initalising modem" and seems to get stuck. The TR light on the modem remains on then. TR in the book says 'ON if modem receives a DTR signal from computer. Always on (modem ignores DTR) if the DTR override is ON (&DO)' I'm not sure what that means. I purchased the modem second user, so I'm wondering if it is a problem with the modem. I don't believe it is the serial port as I have 2, one which is being used by my mouse. I have tried swapping them over and the mouse still works. Any help gratefully received. Further specific questions are: 1. Where do I find out what the error codes mean? 2. Did I buy the wrong type of external modem?

And tt has been several years since I used a modem but the switches should be set to 1,3,5 down and the rest up. (1) DTR flow control, (3) Display Result Codes, (4) Auto Answer (also can be overriden with ATS0=<NUMBER Rings of> or 0 for off. I would try to talk to the modem directly through "minicom -s". You will need to tell it which port you are on. Once minicom is running try typing the following: "AT&F1E1&W". That should set the mode to factory default and store! it in it's first NVRAM location. You should get an "OK" back. If you don't get an OK try to type "AT" and see if you get an OK. You should also see the "TR" and "RD" lights flash. If any of this does not happen there maybe a physical problem. If you get an OK then the problem is probably in your PPP setup. -- Chris On Tue, 2004-04-13 at 17:04, J Simpson V21 wrote: > Hi > > I recently purchased the above external modem as my internal modem was > apparently a softmodem and I didn't have the skill to make it work with > RedHat 9. > > I have used the Internet Configuration Wizard to set up the modem, when I > click on "activate" it says "failed to activate ppp0 with error 8.
