similar to: [PATCH]: Cygwin port of 2.2.0p1

Hi, the following patch is a (hopefully least intrusive) extension when sshd is started so that it daemonizes itself. In that case Windows 9x/Me has a slight problem with sshd as soon as the current user logs off. The sshd daemon will be killed as well. Since installing services is very different between NT and 9x, the way used for NT boxes isn't working well for 9x. For that reason

Hi, attached is a patch which solves the following problem: Sometimes scp could hang in Cygwin when used as remote end using the -t option. This is due to a binmode/textmode problem which could be raised by the login shell which is used by the user and it's setting of textmode on stdin. The patch solves that problem by explicitly setting binmode on stdin. Besides solving the hanging

Hi, the following patch fixes a potential security hole in the Cygwin version of sshd. If you're logging in to a Cygwin sshd with version 2 protocol using an arbitrary user name which is not in /etc/passwd, the forked sshd which is handling this connection crashes with a segmentation violation. The client side encounters an immediate disconnect ("Connection reset by peer").

I had to update the Cygwin port for two reasons: - scp could fail because of another textmode/binmode problem. - Privileged ports are not privileged on Windows and there's no coherence between privileged user and uid 0. So I send the complete patch again with the above changes. ChangeLog: ========== - Makefile.in: Changed to support $EXEEXT transparently. Added `cygwin_util.o' to

I have encountered a problem with using OpenSSH 2.3.0p1 on 64-bit HP-UX 11.00 systems. This bug does not exhibit itself on any 32-bit HP-UX 11.00 or HP-UX 10.20 systems that I have built 2.3.0p1 on. OpenSSH 2.3.0p1 was built with HPs ANSI C compiler with OpenSSL 0.9.6 and zlib 1.1.3. The problem is with the call to vhangup(2) in sshd when interactive sessions are started. The problem does not

Hi, OpenSSH 5.9 is almost ready for release, so we would appreciate testing on as many platforms and systems as possible. This release contains a couple of new features and changes and bug fixes. Testing of the new sandboxed privilege separation mode (see below) would be particularly appreciated. Snapshot releases for portable OpenSSH are available from http://www.mindrot.org/openssh_snap/ The

Hi, the following patch removes some of the Cygwin specific code from OpenSSH. Since Cygwin is able to change the user context on NT/W2K even without a password since the new Cygwin version 1.3.2, there's no need anymore to allow changing the user context only if the sshd user is the same user as the one which logs in or when a password is given. For that reason the whole function

Hi, I have left this slip through already too long.

Hi All. I tried building -current on Cygwin but got a couple of minor errors. The first is in auth-passwd.c where it appears Ben got a bit over-enthusiastic cleaning up :-). The patch restores the relevant "#ifdef HAVE_CYGWIN" fragment. The second is in the send-break code in session.c, which won't compile because Cygwin apparently doesn't have TIOCSBRK and TIOCCBRK ioctls.

Windows usernames are case-insensitive and almost any Unicode character is allowed in a username. The user should be able to login with her username given in any case and not be refused. However, this opens up a security problem in terms of the sshd_config Match rules. The match rules for user and group names have to operate case-insensitive as well, otherwise the user can override her settings

Hi, the following patch checks if OpenSSH is running under a Cygwin version >= 1.3.2 which allows switching user context without password. Otherwise sshd allows changing the user context only if password authentication is used as it was before.

Hi All. While wandering in auth-pam.c I noticed that there's a few Portable-specific escapees from the xmalloc(foo * bar) cleanup. There's also a "probably can't happen" integer overflow in ssh-rand-helper.c with the memset: num_cmds = 64; - entcmd = xmalloc(num_cmds * sizeof(entropy_cmd_t)); + entcmd = xcalloc(num_cmds, sizeof(entropy_cmd_t));

Hi, since the previous port of OpenSSH to Cygwin, there's happened a lot with Cygwin. We have worked hard to allow a more smooth porting of UNIX applications which results in two major advantages: - There's no need to use so called `text mode' in open calls anymore. - With only less interventions in the applications code the concept of real and effective uid's is supported

I am enclosing a context diff of the changes that I made to get openssh working on UWIN. UWIN is a UNIX operating system layer that runs on Win32 systems. For more information on UWIN go to http://www.research.att.com/sw/tools/uwin/. I also ran configure using -with-cppflags=-D_BSDCOMP=2. I don't know where that information would go with the source code. Let me know if you need more

Hi, the attached patch file contains two patches in one: - contrib/cygwin/ssh-host-config: Create sshd_config according to latest changes. - openbsd-compat/bsd-cygwin_util.c: Rewrite a bit to allow easier retrieval of Cygwin capabilities from version number (uname). For Cygwin versions beginning with API minor version 56 assume ntsec being on by default. Thanks in advance for applying

Hi, the following patch by Pierre A. Humblet <Pierre.Humblet at ieee.org> allows to use more than one uid on 9x/Me boxes which is currently blocked due to the behaviour of Cygwin's security code. After this patch is applied to sshd, we can safely change the affected code in Cygwin. Thanks, Corinna Index: session.c ===================================================================

The attached patch should solve the following problem: ssh-agent creates a temporary directory under /tmp with '600' permissions. The actual socket file is created in that dir using the default umask. That's no problem in U*X systems since nobody but the owner of the directory can read the socket file. Unfortunately, Windows has a user privilege called "Bypass traverse
