similar to: AllowTcpForwarding

Hello List. ? i?m trying to setup a limited SSH server with SFTP. The requirements: -????????? There are users to whom only SFTP should be available. (sftp-only group) -????????? There are users to whom SFTP and shell access should be available (admin group) -????????? SFTP clients have to authenticate with username and password -????????? shell users have to authenticate with private key.

I've configured OpenSSH_5.3p1 to only allow sftp connections (openssh chroot functionality). i.e. Subsystem sftp internal-sftp Match group sftpusers ChrootDirectory /chroot/%u X11Forwarding no AllowTcpForwarding no ForceCommand internal-sftp So far everything works correctly with sftp but when a user ssh's or scp's to the box the login

for the A nat B C connect back to A using -R 2222:localhost:22 pattern, (see diagram at https://github.com/daradib/sidedoor) I want to limit B's user to just what is needed to do the port forward. I am hoping this is documented, but I can't find much more than "you should future out how to secre it." I setup an ansible playbook to instal and configure sidedoor on A. I have

Hi! I tried with all available options to disable forwarding-only connections, by: "AllowAgentForwarding no AllowTcpForwarding no" This had no effect, so what I got in effect was dummy connections. I would like to disable this "class" of connections altogether. The outcome will be that all authenticated connections will lead to a command, be it /usr/libexec/sftp-server

Hi folks, (3rd time I am sending this message, none of the other appear to have made it through!) Using "OpenSSH_6.9p1 Ubuntu-2ubuntu0.1, OpenSSL 1.0.2d 9 Jul 2015" on the server, "OpenSSH_7.2p2, OpenSSL 1.0.2g 1 Mar 2016" on the client. I am trying to use sshtunnel with StreamLocal forwarding to enable me to connect back to the client's ssh port, without having to

Hi, The code definitely attempts to unlink any old listener beforehand (see misc.c:unix_listener()) so I don't understand why that isn't being called. You might try simulating your configuration using sshd's -T and -C to make sure the flag is correctly being set. Could chroot be interfering? Some platforms implement additional restrictions on devices and sockets inside chroot. -d

Hello all R-user I am relative new to the R-environment and also to GLMM, so please don't be irritated if some questions don't make sense. I am using R 2.0.0 on Windows 2000. I investigated the occurrence of insects (count) in different parts of different plants (plantid) and recorded as well some characteristics of the plant parts (e.g. thickness). It is an unbalanced design with 21

Dear developers, The ProxyJump feature is nowadays implemented on the basis of a TCP port forwarding on the jumping host, isn't it? As a result, this is affected by a AllowTcpForwarding=no configuration on the jumping host. So, may I suggest a variant based on Unix sockets (such as -L or -R does). Nice idea, isn't it? Any volunteer to implement this? Best regards Christophe

No answers on secureshell at securityfocus.com I must be doing something wrong or the server seems to ignore my bind request. Port forwarding is working it just bind to all ips and ignores my bind request. I've also tried this with an rfc1918 address opposed to a loopback and had the same results. Google and the archive haven't helped. Thanks in advance for your time and consideration.

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

Thanks for these 3rd party hacks! I don't trust them. There must be such feature in openssh out of box. So the most secure/easyer method of giving sftp access to porn collection is: Damiens sftp-server chroot patch, which I hope to see in openssh one day :) http://marc.info/?l=openssh-unix-dev&m=116043792120525&w=2 # useradd -d /data/p0rn -m share /etc/ssh/sshd_config: Match user

Hi! I want to set a OpenSSH server which restricts some users to only chrooted SFTP, while others have full/normal ssh, scp and sftp access. Most or all guides on the web say that I should enable the config line "Subsytem sftp internal-sftp" among other things, but I've found out that this only causes non-restricted users to not be able use SFTP at all, only the chrooted users.

hello- i would like to be able to have users access a specific set of ports (and no others) on a machine running an ssh daemon via ssh's port-forwarding. i was thinking of doing this by not providing shell access (so using an appropriate command="command" option in each user's authorized_keys file), but i did not find an appropriate keyword for the sshd configuration file

Hi OpenSSH devs, I?m wondering if the following has any merit and can be done securely ... If you could match on principals in the sshd_config, then (for example) on a gateway machine, you could have something like /etc/ssh/authorized_keys/sshfwd: cert-authority,principals=?batcha-fwd,batchb-fwd? ... /etc/ssh/sshd_config containing: Match User sshfwd PubkeyAuthentication yes
