Hello, I know this is likely to give me a brute force attack hit, but the only thing anyone can accomplish by ssh-ing to my machine is to provide me with a tunnel into your machine. So don't bother. Anyway, my server machine is running this: /usr/bin/ssh -X -R ${port}:localhost:22 -o BatchMode=yes \ -o StrictHostKeyChecking=no ${user}@${my_home_machine} On my local machine: ssh -vvv -X

I found this problem when working with the Suse9.1 distribution, but have since reproduced it with a vanilla build of Openssh (openssh-3.9p1.tar.gz). Basically I cannot get a command like this: XXXX>ssh -vvv -1 -o "RhostsAuthentication yes" AAAA to work. Yes the appropriate settings are in the servers sshd_config file. Hostbased protocol 1 ssh using rhosts between computers is

Hi! Several people noticed problems with openssh Version 1.2.2 through 1.2.3 related to X11 forwarding under Linux.

I have just installed openssh-1.2.2p1-1 on two of my machines and I have one problem. I have X11Forwarding yes in my /etc/ssh/sshd_config but when I try to ssh to that machine I get this when i try to start rxvt: [pucko at b202 pucko]$ rxvt X11 connection rejected because of wrong authentication. X connection to b202.ryd.student.liu.se:11.0 broken (explicit kill or server shutdown). [pucko

Hi, the following patch patches the files in contrib/cygwin. The changes are necessary to allow a better support of privilege separation. On NT machines the script asks now if it should create a user called "sshd" and all that. Additionally it creates the /etc/ssh_config and /etc/sshd_config files follows the latest versions. Would you mind to apply this to the official OpenSSH

Hey everyone, I wanted to add support for denying PTY allocation through OpenSSH. I'm not certain if this is quite thorough enough for all cases, but for me it might work for the moment. I know that you can currently do this through authorized_keys, but as far as I know that only works for an actual key. In my use case, I wanted a user with no password which is forced to run a specific

There is nothing in /var/log/secure. Also a diff between the config.h 's without and with --with-ssh1 is attached. I have a centos-6.7 under

Greetings, I'm running OpenSSH_2.5.2p2, and OpenSSL-0.9.6a, on BSD/OS 4.0. Following the FAQ, I added the following line to my sshd_config in order to enable X11 forwarding: X11Forwarding yes Now openssh is disconnecting my sessions immediately after authentication and login with the following error messages: "error: socket: Protocol not supported" "Disconnecting: Command

Hi, the following patch to contrib/cygwin/ssh-host-config creates /etc/ssh_config and /etc/sshd_config according to the current default config files. Could somebody please check it in?

I do not often use X11 - but when I do I prefer to enable X11forwarding, and when finished - turn it off. This is preferable, imho, to having "clear" X11 processing when local - and otherwise impossible when working remote. Working with openssh-7.5p2 I cannot figure out what (extra) I need to do with sshd_config to get it working. I know that there is a security-fix starting with

I've installed OpenSSH 2.9p1 on Solaris 2.7 and I am trying to get rhost authentication working. Something appears to be wrong with the client side as I can do rhost auth with a ssh1.2.27 client. Any help would be appreciated. /opt/openssh-2.9p1/etc/ssh_config is: ForwardX11 yes RhostsAuthentication yes /opt/openssh-2.9p1/etc/sshd_config is: Port 22 IgnoreRhosts no StrictModes yes

Hi, I have attached two new shell scripts `ssh-host-config' and `ssh-user-config' which will replace the script `ssh-config' in the next Cygwin OpenSSH release. Could somebody with write access please remove contrib/cygwin/ssh-config from the OpenSSH repository and add these two attached files instead? The third attached file is the diff for contrib/cygwin/README. Thanks in

Hi all! I've a server with Centos 4.0 without X server, but I need use mysql-administrator from other pc with X server. In the moment to export X from the server this message show me: [root at server]# mysql-administrator (mysql-administrator-bin:19124): Gtk-WARNING **: cannot open display: The /etc/ssh/sshd_config have X11Forwarding yes and the /etc/ssh/ssh_config have Host *

Hi folks, just I installed openssh 2.1.1p4 on a sco OpenServer 5.0.5 machine and it works fine. The only problem I have is the X11 forwarding. I have allowed this feature in the /etc/sshd_config and the /etc/ssh_config, respectively and the /usr/bin/X11/xauth program was in the PATH during compilation. As you can see in the logfile the sco system enables the X11 forwarding and sets the DISPLAY

What has to be installed on a host for it to do X11Forwarding in SSH? My (FreeBSD) workstation at home is behind NAT. From home, I can SSH to a FreeBSD firewall at work, and from there I can get to other hosts around the internal network there, some of which run X clients. Does X have to be installed *on the firewall* for me to forward X11 connections from the X clients back to my workstation

I can't seem to get the /etc/shadow password expiry working on 3.8p1 on Solaris 8. It works fine with 3.7.1p2 and pwexp26. Logins aren't affected after a 'passwd -df' or 'passwd -f'. Here's the configure, using gcc 3.2: --prefix=/usr --sysconfdir=/etc/ssh --with-tcp-wrappers \ --without-pam --libexecdir=/usr/sbin --mandir=/usr/share/man \ --with-shadow 'uname
