high packet loss w/ packet size > 1024 byte

high packet loss w/ packet size > 1024 byte

Post by Axel Morgne » Sun, 19 Oct 1997 04:00:00



Hi!

When Im pinging with packet sizes > 1024 bytes I get more and more
packet loss. The border of 100% packet loss seems to be at around 1140
bytes packet size.

I use a no-name NE2000-comp. ISA ethernet card, its a RJ45 thin
ethernet twisted pair-connection to a router.

The other hard- and software is:

Pentium 133, ASUS T2P4-MB, Linux 2.0.30

Anyone an idea?

Ciao,

-Axel.

Are you pinging ip's internally in your own network or externally
to the outside world?
If packet loss is internal,check for ethernet collision (if that's what
you are using. Collision can be causeed by bad hubs, tranceivers or
cables.
If packet loss is external and you have an data circuit >=56K.
Have the telco check the line provisioning. Some ISP's use B8ZS line
encoding while others use AMI. Make sure your telco is using the same
kind that you ISP is using.
If you have a dail-up connection, I can't help you.
Hope that helped a little.

1. FreeBSD File System 512 byte-blocks --> 1024 byte-blocks

I was installing FreeBSD 2.1 several times trying to get things right
and I noticed that on my last install, the df command would return file
system block sizes of 512 bytes. All of my previous installs were of
1024 byte blocks. I always used the auto feature during the
partition. Does anyone know why it changed? And is it possible to change
the block size back to 1024bytes w/o reinstalling FreeBSD? ...what
gives?

Any suggestions would be appreciated.
