Hi, has anybody seen a patch that provides socks version 5 support for the dynamic portforwarding feature? I?ve seen thats implemented in ssh.com?s ssh version, but found nothing about openssh. Only thing i found was a patch to provide socks4a. cu sleepi

Hello, 1) Thanks - shorewall save me a lot of time! 2) I try - exactly: I must :-) - configure a VPN server behind 2 NATs. My situation: RoadWarior - INet - ISP Router (NAT+PortForwarding) - Inetranal Router (running Shorewal, NAT+PortForwarding) - Inetranl VPN Server If RoadWariror try to connect Internal VPN Server then connection failed with "GRE: Bad check chcksum from pppd"

I have the following forced up mew by evil telco problem: - One IP - Homebrew LAN - portforwarding for some services. - extra PPTP/ppp layer to an internal 10.* network which mutilates DNS answers. Setup: Machine A has ip a.b.c.d (real IP) and is reachable over ADSL with it from the world. It does NAT for an internal LAN 192.168.0.0/24) and has portforwading turned on for some ports (eg 80)

Hi all, currently I am considering writing a patch for OpenSSH that will allow portforwarding using the control_master unix domain socket. The idea is to introduce an extra SSHMUX command, SSHMUX_COMMAND_SOCKS, which will then pass control to the normal socks functions used for dynamic forwarding. The main reason for me to write this patch are: - some more control over who gets to connect to

Hi There, I am also trying to do the same for my network. I have two links from different ISPs and I want to configure a failover and load balancing Linux router. I am facing same problem here, that how to detect link failure and let Linux box switch the gateway. I know it works when the first gateway is physically down and not reachable. But what to do if my link is up but there is problem

Hi, A friend of mine has 2 lines of 512kbps terminated in two Linux boxes. He now want to remove those 2 boxes and have some device which will loadbalance the two ISPs and also have a failover arrangement. But he has agreed to give me a chance to do it on Linux for my own satisfication. Is this easy to do with lartc? How do I go about it exactly? I have very less time to do it since his

Has anyone heavily exercised the TCP connection forwarding features in openssh? I use this feature quite extensively for secure web surfing. I run a ssh command like this: ssh -c blowfish -L3128:127.0.0.1:3128 squidmachine Then I set up Netscape on my local machine to use 127.0.0.1:3128 as a proxy server. Needless to say, this exercises the TCP connection forwarding feature quite heavily. This

Hello all, I encountered a problem when trying to setup a remote portforward using OpenSSH 3.5p1. If the port that I was trying to listen to on the remote side was already in use, a message 'cannot bind to port: 5000' was written to the syslog, but the connection still persisted. I had no way on the client side to know that the listening wasn't taking place. that is, the

hi, I''ve a dedicated internet link 512k with a cisco router, and now, I want to upgrade bandwidth with 8 ADSLs (512k each) then: - build kernel 2.4.27 with pachs: - patch-o-matic-ng-20040621 : CONNMARK, H323, etc... - http://www.ssi.bg/~ja/#multigw Julian''s patch. - Activate "equal cost multi path" (Advanced Router-Networking Options) and so on -

Heya, I'm trying to convince my company to use OpenSSH instead of the commercial SSH version. I need a little help: 1. What features does OpenSSH offer over commercial SSH (besides being free and open source of course)? 2. Our lawyers want details on the licensing / patents stuff. I have the high level details from the OpenSSH page. I need the nitty gritty like RSA patent# and

I've got a setup where I run nfs over ssh on several distros, and it's been working like a charm on suse, mandrake, redhat 7-9 etc, but I've been unable to get it to work on CentOS. First I set up ssh portforwarding using: /usr/bin/ssh root@<remotehost> -L 250:irc.dynip.no:2049 -f sleep 60d & Then I mount using the following params in fstab: localhost:/somedir

Hi, I discovered a strange problem with the latest version (2.9.9p2) and previous versions of OpenSSH when using portforwarding und Solaris 8 x86. It seems like the getaddrinfo() function on Solaris 8 x86 is somehow broken, instead of binding a port to 127.0.0.1, OpenSSH tried to bind it to 1.0.0.127 (1.0.0.127 was the ai->ai_addr returned by getaddrinfo() in channel.c). I could not

I have just uploaded a new snapshot to: http://www.mindrot.org/misc/openssh/openssh-SNAP-20001114.tar.gz This snapshot includes Markus Friedl's new SSH2 RSA authentication work and -R portforwarding for SSH2. Please give these a good test. The new RSA authentications works similar to the current SSH2 DSA keys, but requires a little modification to config files. Currently RSA key cannot be
