Try the "-a" option to dump, which tells it to output until it receives a
write error. Otherwise, it tries to chop up the dumps into tape-sized pieces
(even when writing to stdout), and the default tape size seems to be tiny.
dump does not seem to be involved :
On client :
[EMAIL PROTECTED]:/tmp$ if (/usr/bin/ssh -c blowfish [EMAIL PROTECTED] \
/usr/bin/nc -lv 24864 \>/tmp/file.1m &); then \
/bin/dd if=/dev/random bs=512k count=2 | \
/usr/bin/nc -v s-backup 24864; fi
On remote, I only have a 1024 bytes file size:
[EMAIL PROTECTED]:/tmp$ ls -l
-rw-r----- 1 backup operator - 1024 17 feb 22:52 file.1m
But, if on s-backup :
[EMAIL PROTECTED]:/tmp$ /usr/bin/nc -lv 24864 | /bin/dd of=/tmp/file.1m
And on client :
[EMAIL PROTECTED]: dd if=/dev/random bs=512k count=2 | \
/usr/bin/nc -v s-backup 24864
I get the expected result on s-backup:
[EMAIL PROTECTED]:/tmp$ ls -l
-rw-r----- 1 backup operator - 1048576 17 feb 22:54 file.1m
So, I think that ssh is the one that break the transmission.
