similar to: ssh client and privileged ports

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

FINALLY, it's here. You can now tell SSH which address to bind to for every single port forwarding option! This patch allows you to pass the following as ssh command line options: ssh -L 192.168.1.55:1234:localhost:80 -R ::11:22:aa:bb/80/localhost/80 etc. Or as normal config file options: LocalForward ::11:22:33/1234 localhost/80 RemoteForward 1.2.3.4:80 localhost:80 It will also

Hi! Sorry if this has already been reported or even fixed, I didn't search very thoroughly. Here's a patch to make dynamic -R remote port allocation work even when not connecting as root. Without the patch I got that "Server has disabled port forwarding." message visible in the patch. OpenSSH version I'm using is openssh-5.2p1, compiled from official source package,

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

FreeBSD doesn't have a fixed range of reserved ports, although it still has IPPORT_RESERVED for compatibility; instead, the last reserved port number is indicated by the net.inet.ip.portrange.reservedhigh sysctl, which defaults to IPPORT_RESERVED - 1. The attached patch modifies add_local_forward() to use this sysctl instead of IPPORT_RESERVED on FreeBSD. DES -- Dag-Erling Sm?rgrav - des at

These patches implement a new mux client request to list the currently opened TCP forwardings. It also removes some todos regarding keeping the list of forwardings in the options up-to-date. Bert Wesarg (6): attach the forwarding type to struct Forward merge local and remote forward lists generate unique ids for forwardings to be used for identification remove closed forwardings from

Hi all, I'm very new in this list, as looking for codes to plug up the lack of functionality of "Protocol 2 Remote Forwardig". Fortunately, I could find it in MARC's archive. Mr. Jarno Huuskonen posted the codes in Sept, last year, and I tried applying it to my FreeBSD box environment. I couldn't apply an original patch, of course, for incompatibility of virsion. The

The openSSH ssh command appears to not use a source privileged port (no matter what the options/configs) if the target port isn't a privileged port. For example: ssh -p 22222 foo.ucla.edu would never try to connect from a privileged port. Even with useprivilegedport=yes. This disallows .shosts RSA host authentication without a password. This breaks compatability with ssh-1.2.27 and

It looks like there is good support for limiting connections on the server side when the client uses the -L flag. What about support for server side connections (listens) when the client uses the -R flag? I am looking for an equivalent to permitopen that says what ports are valid for the remote host when using the -R flag. As it sits now, an unscrupulous ssh user can bind to any port above 1024

The patch below implements a couple of features which are useful in an environment where users do not have a regular shell login. It allows you to selectively disable certain features on a system-wide level for users with a certain shell; it also allows you to control and audit TCP forwarding in more detail. Our system is an email server with a menu for the login shell; we selectively allow port

Hi ! Here's a patch to add remote port forwarding support (protocol 2) for openssh. I have tried to test that it works like it should but a more thorough testing is needed. This patch adds both client/server support. The patch should be applied to openssh-2.1.1p4 source tree. Also included is a PortForwarding sshd_config option, new ./configure option --disable-forwarding that should make it

Hi all. I was getting something working over socks5 and was trying to figure out why it kept using socks4. It wasn't, it was just a misleading debug message....

Hello, Today I tried using "dynamically assigned" port for remote listener, by requesting listener on port 0. This is supposed to create a listener on a port choosen by server. Everything seemed OK (the choosen port was sent back to client), but forwarding was refused. So I checked the source. in channels.c, function: channel_setup_fwd_listener /* *

How about putting it in defines.h instead? includes.h includes netinet/in.h from whence the definition of IPPORT_RESERVED

Hi everybody, This is more of a part of a larger wishlist: I found out that when a peer probe is performed by the user, mgmt/glusterd write a file named after the hostname of the peer in question. On successful probes, this file is replaced with a file named after the UUID of the glusterd instance on the peer, while a failed probe causes the temp file to simply get deleted. Here's an

Hello, I am attempting to join a Windows 7 computer to a Samba 3.4.5 I setup. When I attempt to join the domain the Windows 7 computer says: "A device attached to this system is not functioning." There are no obvious errors in the system logs on the Windows 7 machine or the samba PDC. I can browse/map a drive to the PDC and access the files. Does anyone know what is going on? *

Hi ! Here's an experimental patch for openssh-2.1.1p4 to add support (to openssh client) for -R (protocol 2). So if you have access to a commercial ssh2 server (that allows port forwardings) could you test this patch. (Note the openssh server doesn't have support for -R with protocol 2 so testing with openssh server won't do much good). To test remember to use -o "Protocol

Hi, At the n2k10 OpenBSD network hackathon, I finally got some time to clean up and rewrite the ssh(1) client multiplexing code. The attached diffs (one for portable OpenSSH, one for OpenBSD) are the result, and they need some testing. The revised multiplexing code uses a better protocol between the master and slave processes and I even bothered to write it up :) It tracks the control sockets

I have a few patches for AIX. The patchfile is attached below. The patch has been tested on AIX4.2 and AIX4.3. The patch is on openssh-1.2.1pre25, with openssl-0.94, using RSAref. 1) authenticate support - this function allows the system to determine authentification. Whatever the system allows for login, authenticate will too. It doesn't matter whether it is AFS, DFS, SecureID, local.
