similar to: [PATCH] fix sftp to preserve permissions and uid/gid

Folks, I've noticed poor performance using sftp. If anyone has any advice on how to improve performance, I'd like to hear it. Test simply involved transferring a single 143MB MP3 file using defaults for all the program configs. The opensshd 3.0.2p1 server is used in all tests. Software: openssh suite 3.0.2p1 psftp (putty sftp client) latest dev snapshot pscp (putty scp client) latest

The included patch for openssh 3.0.2p1 implements overlapping read requests for the sftp client. It should be able to handle weird cases such as shriking files and reordered responses. This is only the first shot, and I'd be happy for any comments. I plan to implement something similar for the write path if this works out well. The maximum number of outstanding requests is quite high at

we have implemented this function for 3.1p1, and have been using it in production sense may 2002. The patch has been ported to 3.7.1p2, we have been using it in 3.7.1p2 for awhile, if anyone is interested, here it is. This is the same patch David Bradford talked about on 2002-06-05 Regards, Greg Hayes diff -u -r openssh-3.7.1p2/sftp-client.c openssh-3.7.1p2_sftp/sftp-client.c ---

This is the LAST version I plan on doing.. If I hear no feed back good or bad. Then I'll assume I've wasted my time on a feature that people whine about but don't care to try. This is against 3.0.2pX so it should be VERY easy for anyone to test. - Ben diff -ur openssh-3.0.2p1/misc.c openssh/misc.c --- openssh-3.0.2p1/misc.c Tue Jul 3 23:46:58 2001 +++ openssh/misc.c Wed Feb 6

Hi, the sftp client from openssh package can't upload data from local pipe to remote file. For example, such a command fails: $ cat file | sftp -b <(echo 'put /dev/stdin /directory/filename') -i ~/.ssh/key user at remote.host sftp> put /dev/stdin /directory/filename /dev/stdin is not a regular file What is a purpose for such a behaviour and limitation? As experiment, I removed

I saw several questions regarding 'resume transfer' support in sftp come up, in the archives, but no real satisfying answer. I had a particular itch myself, so I scratched it with a quick hack. Patch attached, since it's not really big. To explain, I need to use ssh (scp or sftp) to transfer files to and from a Windows box. No other method is available. And the Windows machine has no

Hi, I've already discussed this issue in SSHSCI's SSH 2.2 context on ssh at clinet.fi list. My standpoint is that it's wrong and meaningless to perform chown in sftp-server as the file is most likely copied between systems with distinct accounting system where user is not necessarily (and even unlikely) has same numeric user id. The original bug report was that user couldn't

This patch is against OpenSSH 3.7.1p2 sources. It adds recursive (directory) downloading and uploading. Criticism/suggestions welcome. I would imagine the time official support is added, recursive operations will be handled on a per-command basis as a flag as opposed to a global toggle command (such as get -r)? diff -ru openssh-3.7.1p2/sftp-int.c openssh-3.7.1p2-patched/sftp-int.c ---

Again, this has been lightly tested. I think there still are a few glitchs. 1. stole progressmeter() from scp.c - clean up and simplified a little to remove the 'flag' status. It now understands how to initialize itself and how to terminate itself. Along with a malloced status bar instead of the original fix width bar. 2. removed all initialization code from scp.c for progressmeter()

I think my first send was eaten by elm.. Yuck I hate this programm.. Anyawys, first the disclaimer: This is barely tests, I submit this to the general population, but I will not submit this for review of rest of the OpenSSH team. Mainly because it is horrible at best. dealing with alarm() in a sane way is not fun. It does not compile clean, but works. IF anyone cares to clean it up..

This is another take on logging for sftp-server. Given the number of private email requests I've received for this patch, I assume there is signifigant enough interest to request it be reviewed for inclusion into the release. The patch is against 3.1p1, and is completely disabled by default. To enable logging, one must use compile time directives (-DSFTP_LOGGING). This was done due to prior

This patch adds all the missing commonly used UNIX attributes: st_dev, st_ino, st_nlink, st_rdev, st_blocks, st_blksize, st_ctime. In addition it extends st_atime and st_mtime to 64bits, and adds nanosecond resolution to all three timestamps. This is implemented as an extension to the ATTR message. This patch alone is sufficient for SSHFS to be able to use these attributes. The following two

Sorry to repost, but I finally have the code on a machine that has diff -u, and I've updated it for 2.9p2. Attached is the unified diff to add logging of SFTP activity to auth.info. If there is a more proper way to contrib patches, please let me know. Cheers, Jason # "Jason A. Dour" <jason at dour.org> http://dour.org/ # Founder / Executive Producer - PJ

This patch adds a readonly mode to scp and sftp_server. This allows clients to only read files from the server, but not to write them.
