I have found a problem with port forwarding on Mac OS X (10.2 and 10.3). When I forward a port to localhost, as in ssh -R 40404:localhost:40404 somehost ...and the remote system makes a connection on this port, I get the message getsockopt TCP_NODELAY: Connection reset by peer I have tracked this down to the loop in connect_to that gets a list of addresses from getaddrinfo and tries them

We get the warning above whenever we use a ProxyCommand. We _know_ it's a pipe, so we can't use sockopts on it. So we shouldn't bitch about it. This breaks all kinds of things which use SSH transparently; including pine, which really wants the first thing it receives from an IMAP server to be a valid imap greeting... which $subject is not. $ ssh -o "proxycommand sh -c '(

To Whom It May Concern, Our team has found what we believe to be a bug in the code for SSHD. When creating an SSH port forward between a Linux machine (server) and a machine running Cygwin (client), we were getting buffering of data coming from the server. This buffering caused small ammounts of data to be bursted, instead of sent immediately. Also, since debug output showed that

Hi, attached is a patch by Chris Faylor <cgf at cygnus.com> relative to 2.2.0p1. Description: OpenSSH does not allow port gatewaying by default. This means that only the local host can access forwarded ports. Adding "GatewayPorts yes" to .ssh/config usually does this job. Unfortunately, OpenSSH does not recognize the same hosts.allow/ hosts.deny options as ssh.com's sshd

I know that there was a discussion on this about a year back, and there is a bug 556 this week that mentions TCP_NODELAY. However, when I use ssh through a pipe (e.g., to tunnel through an HTTP proxy using CONNECT) I see: getsockopt TCP_NODELAY: Socket operation on non-socket How do I tell which end is generating this (I'm assuming the local side, which is running through the pipe). Also,

I ran into the following problem the first time I used OpenSSH_3.6.1p2 on Solaris 8 (sparc, 32-bit): $ ssh kiwi Enter passphrase for RSA key '/net/sic/export/ford/home/eggert/.ssh/identity': getsockopt TCP_NODELAY: Socket operation on non-socket Last login: Sat May 10 14:27:01 2003 from ip-66-80-53-59.d Sun Microsystems Inc.

Attached is a patch to allow a user to turn on TCP keepalives for port forwarded connections. It's mainly useful when the connections to the ssh listener are coming from many different boxes, some of which crash, leaving the service on the other side of the port forwarder waiting on connections indefinitely. It creates a new option named "KeepAliveForward" to control this behavior.

1. Does anyone know what may be happening here? When I try to map a drive from a PC, I get the following error: "The account is not authorized to log in from this station.". I can map the drive just fine from my PC. Does anyone know what may be going on here? Any help would be greatly appreciated. 2. Also, whenever I use SWAT, it takes a long time for the information to be

Hello SSH developers, I am sorry if this is not really a bug, and I am missing something, but I am running into an issue with port forwarding in SSH. I am using 3.4p1 of SSH on both sides. I am running the ssh daemon on a Slackware Linux 8.0 machine, and the ssh client is running in Cywgin version 1.3.13. The ssh client is creating about 7 port forwards in a mix of local and remote forwarding

Hi! Here is the patch to support tcp wrappers with x11-forwarded connections. The patch is for openssh-3.0.1p1 but it works fine with 2.9.9p2 too. I've understood that this will not be included in the official version because it adds complexity (?!) to openssh. Binding the forwarded port to localhost doesn't solve all problems. I've understood that you should also implement

It appears that openssh has inherited the dos attack that ssh is susceptible to. This has been discussed on Bugtraq (see http://securityportal.com/list-archive/bugtraq/1999/Sep/0124.html for the thread). There does not appear to be an official for ssh. Attached below is a simple, proof of concept, patch that adds a MaxConnections to sshd_config that sets the maximum number of simultaneous

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

I've had fairly good sucecss with the portable OpenSSH 2.1.1p1 on Irix 6.2. There's one major nit, and a few things that configure got wrong. I'm kinda deep in real work at the moment, so I don't have time to delve heavily, but since configure specifically asked for feedback on this port, I'm obliging. The biggest problem I've run into so far is in the builtin PRNG
