File Offsets for SCP (patch)
I don't know if anyone would be interested in this but I'm including a
patch to allow for offsets when transferring files with SCP.
It's pretty simple and assumes the user knows what they are doing (for
example, if transferring with a wild card the offset would apply to all
files). -A is the number of bytes offset from the beginning of the
files. -Z is the number of bytes inset

Not so. Consider:

BUG: scp -q isn't quiet
If I scp from/to a server that has a banner using scp -q, it still
shows the banner. If I ssh -q to the same server, the banner is
skipped. scp -o "LogLevel quiet" does the trick, but is excessively
cumbersome.

rsync stuck at +- 50 MB/s, cp and scp are +- 200 MB/s
Hi,
I tried different encryptions like arc four, but always with the same result. BTW: googling shows some similar questions and they are stuck on set same speed +-.
But non of that solutions helped me.

High Performance SSH/SCP - HPN-SSH when?
Hi,
http://www.psc.edu/networking/projects/hpn-ssh/
Clearly, the HPN patches significantly boost throughput performance.
This enhancement is entirely from tuning the SSH buffer sizes.

ssh / scp slow on 10GBE
Hello list,
right now SSH Tunnel / scp is reaches just around 76Mb/s on my E5 Xeon
using AES-NI but openssl reaches around 600-700Mb/s using 128aes-cbc cipher.
As far as i understand http://www.psc.edu/index.php/hpn-ssh this is due
to very small buffers in ssh / scp.
Is there any work on this? Like autotuning the buffer size? Are there
plans to integrate the hpn patches?
Greets,

scp -q behavior different than documented
Hi
The man page says -q disables the progress meter, but it also disables
all other output.
$ scp -q badhost:/bin/ls .
$ scp badhost:/bin/ls .
ssh: badhost: Name or service not known
I would like -q to disable the progress meter as documented (I don't see
the point of a -q flag if all it does is discards stderr, since I can
already do that with my shell), but you might prefer to update

rsync stuck at +- 50 MB/s, cp and scp are +- 200 MB/s
Hi,
i have two servers, connected to to the lan by 10Gb with 10Gb and DAS
hardware raid.
Each system con read and write locally or to the 10G iscsi by more than
200 MB/s.
Now I have to transfer backups form A to B and doing this with rsync
always stuck at +- 48-50MB/s no matter which options, compressions,
encryption etc I use. Even the plain default rsync is at that 50 Mb limit.

SCP v. SFTP
I was comparing some traces from SCP and SFTP when transferring the same
file 200MB file between the same host pairs. Even when I put SFTP in
batch mode I noticed that I saw 403208 bytes from the receiver in
comparison to 3368 bytes with SCP. I've attached the relevant output
from tcptrace below (the b->a column is the return side of the trace).
Mostly I'm just curious as to what

sshd 'zombie' processes
each scp or ssh I do to a 4.8-stable machine I have gives me two
'zombie' processes:

imp 284 0.0 0.4 5252 2260 ?? I 7:41AM 0:00.01 sshd: imp@notty (sshd)
I had been running 4.8-RC when I first noticed it and reported it.
People here said this had been fixed shortly after 4.8, but it is

further problems Re: scp not found with solaris 8/2.1.0p2
Thanks to Richard June, John Horne and Bosko Radivojevic, who
pointed out that I probably need to set the configure-time option
--with-default-path, so I did this (rather than make symlink
messes, which I'd prefer to avoid) :
1489 ./configure --with-default-path=/bin:/usr/bin:/opt/local/bin --prefix=/opt/local --with-random=/dev/random

scp with different users
This may be a dumb question, but is there any reason why
scp a at b:c d:
fails, where
scp a at b:c .
scp c d:
succeeds?
I get "Host key verification failed.". I'm using nothing more complex
than RSA authorized_hosts based authentication.
I'm seeing this on openssh-client 1:5.8p1-1ubuntu3 and
OS-X 10.6 OpenSSH_5.2p1, OpenSSL 0.9.8r 8 Feb 2011.

scp not tolerant of extraneous shell messages
I spent some time debugging a failing Scp that turned out to be caused
by the remote shell producing messages on Standard Output that aren't
part of the SCP protocol.
Scp from a remote system works by running another Scp on the remote
system. The remote Scp writes SCP protocol messages (and file data)
to its Standard Output, which the local Scp sees as Standard Input.
But it's

DynamicWindow Patch
We have developed a patch that enables changing the SSH window size
using the tcp window size as the source. This allows SSH to obtain
maximum use of the bandwidth on high BDP links.
We also have a page that describes the changes and performance.

The patch against CVS is included here.
