Damien, What is the best document to use for documentation on SFTP? In other words, if I want to build an SFTP client library based on libssh.a, is there documentation about the series of messages I need to send over the wire?

Hi folks. FYI: There's a discussion[0] about keystroke timing attacks against SSH going on on the cryptography mailing list. Would be interesting to hear the opinion of some OpenSSH folks what SSH/OpenSSH is doing against this and what could maybe be don in addition. Especially since the main idea behind the attack is obviously not limited to the initial authentication phase when a password

IPsec Pre Shared Key for enterprise wireless is worse than PPTP according to https://www.cloudcracker.com/blog/2012/07/29/cracking-ms-chap-v2/ . Make sure IPsec is used with certificates instead. tinc is an educational project sponsored by a university aiming to grow awareness of encryption over the public internet. It does not have a marketing department. Criticism is welcome. Think of

No I'm referring to "sshd -ddd" (preferrable on a high port like -p 8080 so you don't break your current ability to connect to the machine). As clearly the server is rejecting it. And only the server side debug can tell us that. - Ben Nick Stanoszek wrote: > I am using an AWS ubuntu 14.04 server...is that what you are asking? > > On Tue, Jul 28, 2015 at 10:00 PM,

Hi OpenSSH, I encountered that SSH will hang over after I input the password. Could you help show me how to resolve this problem? Thanks for your help. Please find the ssh debug info and my ssh version as below. $ ssh -vvv user1 at remote_host OpenSSH_6.9p1, LibreSSL 2.1.8 debug1: Reading configuration data /Users/user1/.ssh/config debug1: /Users/user1/.ssh/config line 36: Applying options for

Can you confirm if the problem is specific to the ssh client, or the ssh server? (Try to ssh into the same server from different client, and to some different server from the same client) On Mon, Oct 24, 2016 at 9:41 PM, Jin Li <lijin.abc at gmail.com> wrote: > Hi OpenSSH, > > I encountered that SSH will hang over after I input the password. > Could you help show me how to

Hello, I'm trying to setup a chroot for one user on my AIX 5.2 system I have tried with openssh 5.0 (don't know where it comes from) and as it didn't work, I have downloaded and compiled the current version (6.6p1) When I connect, password is checked, chroot is done, sftp subsystem is accepted, but I get disconnected without any error Below is all can say about my config (after

Thanks Darren, will check on your response. I am attaching sshd, ssh logs with debug flags. Please see if it gives any hint: when I press ^C in ssh session, no log gets printed in both server/client side.

I don't think it will be easy to identify the problem remotely. You can try logging in with password (if not disabled), or sshing with some other key, or logging into some other user. If you are able to get access to the machine, post the server's error log here. On Mon, Oct 24, 2016 at 9:55 PM, Jin Li <lijin.abc at gmail.com> wrote: > Hi Tanmay, > > The server is not

Hi, at first I'm not sure if this is the correct list to ask this question. But since I'm using winbind I hope you can help me. I try to realize a kerberized ssh from one client to another. Both clients are member of subdom2.subdom1.example.de and joined to it. The users are from example.de, where subdom1.example.de is a subdomain (bidirectional trust) of example.de and
