I have a couple of keys generated using the F-Secure SSH2 client. I have converted those keys using "ssh-keygen -i -f samplekey.txt >> ~/.ssh/authorized_keys". When I try and log into the OpenSSH server using those keys, OpenSSH rejects using those keys. I am under the assumption that this is supposed to work. If I connect using a password, there is no problem. It just does not

On Ubuntu 12.04 / OpenSSH_5.9p1 Debian-5ubuntu1 trying to initiate a connection with hmac-sha2-512 and diffie-hellman-group1-sha1 results in OpenSSH killing the connection after the SSH_MSG_KEXINIT packet is sent. The OpenSSH error logs state the following: debug2: mac_setup: found hmac-sha2-512 [preauth] debug1: kex: server->client arcfour256 hmac-sha2-512 none [preauth] dh_gen_key: group too

Hello everyone.. I am fairly new to the patching format.. so I just decided to post a basic info about how to remove group1 and group14 diffie key exchange in OpenSSH. I know that they are listed as required in RFC 4253 but I don't want a client to have the choice to use a 1024 bit prime for the key exchange. If someone is getting into my system.. they should upgrade to a new client. I am a

I have been contacted by some people who are having a problem with transfer files using OpenSSH 4.1p1 with the HPN patch. I've taken a look at their problem and I don't think its a problem with the HPN code so I thought I would bounce it over here to see if anyone here has some insight. In brief the connection is dying without spitting out an error message during the key exchange. Of

Hello developers, some informations before I come to the problem: At work we're using Open-SSH 3.4p1 under Solaris 8. I compiled the Open-SSH by myself with gcc-3.1. In the gcc is the bounds checking patch included (http://web.inter.nl.net/hcc/Haj.Ten.Brugge/bounds-checking-gcc-3.1-1.01.patch.bz2). With this patch I compiled: - prngd 0.9.25 - zlib 1.1.4 - Open-SSL 0.9.6d Everything

Hello, I recently compiled OpenSSH 4.0p1 with OpenSSL 0.9.7g on my Linux 2.6.11.3 machine. When I try to connect, the connection is immediately closed. When I setup public key authentication, I am able to login using my public key. However password authentication seems to be ignored. I attached debugging output from both the server and client. $ ssh -vvv localhost OpenSSH_4.0p1, OpenSSL 0.9.7g

Greetings, I am trying to cross compile OpenSSH 4.7 for ppc with QNX Neutrino as my OS. I have a workstation with QNX on it (x86) and I have linked the utils used by autoconf to their ppc versions. I have been able to successfully build sshd/ssh. I copy the binaries built on the x86 to the ppc, and sshd works great. I can ssh from any machine to it, but when I try to ssh from the ppc machine to

Hello! I also post here this messages, maybe it's a bug. I have a problem with Cygwin OpenSSH, I hope somebody can help me out. Since we reinstalled our machine we can't connect any external hosts, but we can connect the gateway server. The same box is when booted up with linux (Debian unstable) just works fine. The problem is, that ssh stops at "expecting

Hi there, I have a weird problem with OpenSSH 2.9.9p2 on Solaris 8. Whenever I try to use ssh, scp or sftp to connect to the Solaris box, the connection is closed by the server and the following msg logged thru syslog: "sshd[542]: fatal: buffer_get: trying to get more bytes 129 than in buffer 39" I tried from an RH 7.1 client (2.9.9p2), from a Solaris 8 client (2.9.9p2), and an OpenBSD

A few questions regarding the OpenSSH support for the Diffie Hellman key exchange algorithms: (1) Are the diffie-hellman-group-exchange-sha256", "diffie-hellman-group-exchange-sha1" , "diffie-hellman-group14-sha1" "diffie-hellman-group1-sha1" (as defined in RFCs 4253 and RFC 4419) the complete list of key exchange algorithms supported by OpenSSH? (2) Is there a
