similar to: [PATCH]: auth-passwd.c: Eliminate a Cygwin special case

Hi All, While testing another patch, I found that I could not longer log in as root, even if PermitRootLogin was yes. It seems to be the following code in auth_password: $ cvs diff -r1.48 -r1.49 auth-passwd.c [snip] #ifndef HAVE_CYGWIN - if (pw->pw_uid == 0 && options.permit_root_login != PERMIT_YES) + if (pw->pw_uid == 0 && options.permit_root_login !=

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 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 ===================================================================

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").

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

Dear list, since the order of authentication and AFS token/KRB TGT forwarding changed (around 3.0), we have had problems with users accidentally overwriting their credentials from a "password" login with forwarded credentials. E.g. user A logs in as user B, but stays with the AFS permissions of user A. A workaround is to use "-k" on these sessions, but "it worked without

Attached is the patch for the Cygwin port of 2.2.0p1. As usual I didn't attach the patch to `configure' but only the patch to `configure.in'. BTW: I have attached a gzip'd version of the patch since it's size is > 20K and I thought that it might be too big. The gzip'd diff is < 8K.

Hi, I've sent that patch once already but it seems more or less forgotten in the tumultuous days of the latest vulnerability. It adds a new define NO_IPPORT_RESERVED_CONCEPT which can be defined on platforms not supporting the concept of "privileged" ports only accessible by privileged users but which allow everyone to use these ports. This patch removes some Cygwin dependencies

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

Hi, the Cygwin specific workaround to sleep a second in daemon() isn't needed anymore. We can eliminate it from the OpenSSH sources.

Attached is a patch which adds a new config option, AuthOrder2, to sshd_config.c. The syntax is: AuthOrder2 AuthMethod1[:SubAuthMethod1[:SubAuthMethod2...]][,AuthMethod2...] An example, requiring users to enter a public key _and_ a password, in that order: AuthOrder2 publickey:password The current default behaviour: AuthOrder2 password,publickey,keyboard-interactive Require a public key,

Hi, I have added calls to `check_ntsec()' to the code which checks for the ownership and modes of identity files and directories. As you might know, check_ntsec() tests if owner/modes are supported by the OS (9x/ME=no, NT/W2K=yes), the filesystem (FAT/FAT32=no, NTFS=yes) and the current Cygwin settings (ntea/ntsec).

Hi, I'm terribly sorry that I missed this before 3.7p1 was out. The permanently_set_uid() function fails on Cygwin since the test to revert to the saved uid unfortunately works on Cygwin though it shouldn't. The reason is that a Windows NT process always can revert to its previous privileges. There's no such concept of giving up rights in a process permanently. This is only

OpenSSH 3.4 has just been released. It will be available from the mirrors listed at http://www.openssh.com/ shortly. OpenSSH is a 100% complete SSH protocol version 1.3, 1.5 and 2.0 implementation and includes sftp client and server support. We would like to thank the OpenSSH community for their continued support and encouragement. Changes since OpenSSH 3.3: ============================

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, it would be nice if somebody could apply the following patch. After some months of maintaining the Cygwin version of OpenSSH it finally turned out that USE_PIPES is the better option for Cygwin.

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
