MTU PPP

Mon Apr 12 15:23:35 UTC 2004

Dear sir/madam,
I would like to set the MTU of my ppp0 above 1500.

I tried doing 

ifconfig ppp0 mtu 4464

It reflects that when i put ifconfig that the size of MTU is 4464 but when I dump the traffic the MTU is 1500.

But at the same time if i set 

ifconfig ppp0 mtu 296 

The dumpped traffic shows that the mtu is 296...

Please let me kow if there is a limit on ppp and can that limit be changed,

Thanks

Hi Gurus,

I have installed a virus scanner in between firewall and email server
and port forwarded trafic of port 25 to the virus scanner.

so the incoming mails reaches email server through the virus scanner.

Now I want to route the outgoing mails also via the virus scanner.

Mail server is SENDMAIL and tried smart relay host and got the following 
error. 

Returned mail: Host unknown (Name server: mailgateway.cdfd.org.in: host 
not found) 

mailgateway.cdfd.org.in is the name of virus scanner.

I have included in the /etc/hosts file and is pinging.

Please help me to solve this problem and help me in routing
the mails through the virus scanner.

Thanks
Geetha Thanu

Just a quick note to let you guys know this one was solved. The original 
poster set the RAW printing mode, and let me know in an e-mail that that 
fixed it.

Subject: Can Openoffice 1.1.1 macro run a script from shell?
To: redhat-list at redhat.com

Content-Type: text/plain; charset=ISO-8859-1; format=flowed

Downloaded the last openoffice 1.1.1 and was surprised by the 
improvements of macro-building.

First I have to say I am pretty green about Basic scripts, so I did as I 
would do in ms-Word and use the macro-recorder.

Let us say I have a user want to save directly do a diskette. You have 
a Openoffice macro in basic:

REM ***** BASIC *****
sub Main
rem ----------------------------------------------------------------------
rem define variables
dim document as object
dim dispatcher as object
rem ----------------------------------------------------------------------
rem get access to the document
document = ThisComponent.CurrentController.Frame
dispatcher = createUnoService("com.sun.star.frame.DispatchHelper")
rem ----------------------------------------------------------------------
dispatcher.executeDispatch(document, ".uno:SaveAs", "", 0, Array())
end sub

Is it possible before saving the document to have a line that calls 
bash-shell 'mount /mnt/floppy' ? And after the document is saved 
'umount /mnt/floppy'?
Or is it completely impossible to connect OpenOffice basic scripts to 
bash-shell

Hi, I'm new here. I just installed Redhat Linux 9 on my workstation,
with all the packages installed. The computer is running dual AMD MP
2800s, with 512 MB of RAM. I installed it fine, but when I started
using it more, I noticed that the X server would freeze, and I wouldn't
be able to move the mouse, or use the keyboard; I just had to shut off
the power. I ran the update manager, and it installed the 2.4.30-9smp
kernel, which helped at first, but still doesn't make much of a
difference. Now it seems like every other time I boot up the comp
freezes upon starting Mozilla, Ximian, or just playing some songs with
XMMS. Is this just an issue with the X server version (4.3.0)? 
Sometimes just Mozilla crashes, and I can simply kill the process. But
often I have to reboot.

Thanks for any insight.

Ben

Hi Ben,

I suspect that you will find you have a bad system board. I've seen this
kind of problem before and that has always been what was causing the
problem. 

I've built dual processor systems and run Red Hat on them before,
although I haven't used AMD, and they ran well. One thing to watch,
though, is that the kernel doesn't handle multiple SCSI adapters with
hard drives well. If you have hard drives on more than one SCSI card,
try removing the second adapter and see if the problem goes away.
