Networking :: unable to move/copy more then 2G to another linux

Does the connection get dropped when the file transfer fails?

If so it may be some network related problem. Are the computers just plugged in to one another or is there a network in between (eg the internet).

Not sure if this is relevant: http://osdir.com/ml/os.openbsd.tech/2002-04/msg00120.html

That thread talks about fragmentation problems, hardware problems, or the operating system running out of buffers (what is meant by NMBCLUSTERS on OpenBSD).

The equivalent to upping NMBCLUSTERS for linux is to open a root shell and do:

Code Sample

# sysctl -w net.ipv4.tcp_mem='98304 131072 196608'

(though now I can't see what the default for that key was since I've changed it on my box).

You could do that on both machines and then try the big file transfer again.

There are detailed TCP tuning instructions for high bandwidth 2.4.xx linux here:

Disclaimer: I don't know much about networks.

If you have the spare room (another 3.7 gb on both machines), use spilt then cat.

usage: split [-b byte_count] [-l line_count] [-a suffix_length] [file [prefix]]

split -b 1000m slack.iso slack

And you should get about 4 1000mb files named
slack.aa
slack.ab
slack.ac
slack.ad

(Or slack.001 - slack.004, or the like)

Then after you transfered the files, on the target machine, use cat slack.* > slack.iso

You might want to run a md5 on both computers to check afterwards, but it's not needed
"md5 slack.iso" on each machine then compare the two numbers.

well, it's simple
when trying to copy/move with mc
from a partion on dsl to a partion from another linux mounted through samba in dsl tree
the output is

file size limit exceeded

both patitions are ext3

here below:

dsl@box:/mnt/hdc1/slackware-12.1-iso$ mv /mnt/hdc1/sl*/slackware-12.1-install-dv d.iso /home/dsl/mnt/SL*/320disk
File size limit exceeded
dsl@box:/mnt/hdc1/slackware-12.1-iso$

Could be a samba limitation. How did you mount it? (quick search around shows "-o lfs" might do the trick)
