similar to: sftp-client.c warning clean up.

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

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

Sftp fails to correctly preserve permissions when fetching a file. It adds write permission for the owner (presumably so it can write the file). Sftp also fails to preserve the uid/gid. Added code so that if is running as root, uid and gid are preserved. patch is based on Openssh 3.4p1. *** sftp-client.c@@\main\1 Tue Oct 1 17:26:20 2002 --- sftp-client.c Tue Nov 5 10:22:52 2002

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()

While looking for leaks I came across two old packet APIs which are easy to remove. I'm sending patches for each separately. First, there is the packet_set_connection(int fd_in, int fd_out) function in opacket.c The function relies on a behavior in ssh_packet_set_connection() where, when it is passed a NULL pointer, it will implicitely allocate a struct ssh and return it after then set

One of the features missing in sftp is the ability to transfer a symlink. This patch adds a new command to sftp which performs this transfer. Note that it uses messages that already exist in the protocol between client and server. This diff is based on OpenSSH 3.4p1. *** sftp-client.c@@\main\1 Tue Oct 1 17:26:20 2002 --- sftp-client.c Wed Oct 23 15:57:34 2002 *************** *** 666,672 ****

I've tried to use sieve-filter for my inbox (~6000 messages). It failed after some work with this backtrace: sieve-filter(kas): Error: socketpair() failed: Too many open files sieve-filter(kas): Panic: file script-client-local.c: line 155 (script_client_local_disconnect): assertion failed: (pid >= 0) sieve-filter(kas): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x66a71)

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..

Here's a patch that adds support for the creation of hard links over SFTP. Hard links are not used very often nowdays, but they do still have their uses and this is currently the most often requested improvement for SSHFS. To detect hard links the st_nlink, st_dev and st_ino attributes are usually used. I'll also post patches adding extensions for these and other attributes. Please

Hello, This patch adds client and server support for transmitting the st_nlink field across SSH2_FXP_NAME and SSH2_FXP_ATTRS responses. Please let me know if there anything I can do to improve this patch. I am not subscribed to list so please CC me.

This applies to the OpenBSD --current tree. Don't see why it shouldn't work under portable. Within the patch are the updates I need to make before I'll actually submit it for real, but I figured I'd make a public drop. Since I'm not on this list anymore keep me in the CC: if you want me to respond. I'll continue to work as time permits, but it would be nice if people

I've finally took the time to figure the last few bugs (that I know of). This patch will be submit to be included in a few weeks. This patch should be generic enough for portable without too much hassle. This patch mimics OpenBSD's ftp behavior. I'm not sure like that (e.g. it doesn't put / at the end of directories by default), but that is more a question for the community

Timo, I noticed this core dump from imap the other day from one of our users; there was no assertion. GDB output attached, I have saved the core if you need more information.

Dear OpenSSH Portable sshd developers, I'm having a problem where sshd login sessions are occasionally (as often as once a day) getting stuck indefinitely. I enabled debug messages and got a backtrace of a stuck sshd, and I think I've found the bug. I wanted to run it by the list once before filing. sshd version: OpenSSH_4.2p1 FreeBSD-20050903, OpenSSL 0.9.7e-p1 25 Oct 2004

I am looking through the logging options and wondering if there are a couple of things that we can do 1. Logouts don't seem to show the IP address of the logout, we typically see multiple sessions at a time and wondering if there is a way to tie the logouts to an IP 2. POP logouts show the number of messages retrieved/deleted but I don't see a way to do this with IMAP, is there a logout
