I have a little problem
For years, I've been using SSH with public key authentication to connect to a remote server, and my private key is formatted like this:
Code...
I've tried creating a new key which uses DSA, but I got the same result...
Does anyone know what the cause to this might be?
I have an ssh (OpenSSH_5.1p1 Debian-6ubuntu2) client A and a server B set up for public key authentication as described in [URL]
The problem is the following: ssh asks for a password when connecting from A to B without any other ssh session going on between A and B; but if I connect from A to B whenever there is another ssh session between A and B, either I get prompted for the passphrase I used to encrypt the private key or I get logged automatically.
I already checked permissions on B: .ssh is 700 and authorized_keys is 600. I already tried "StrictModes no" in sshd_config. Printing debug information using DEBUG3 does not any useful insight. Moreover, there is no /var/log/secure (is it supposed to be there?)
Right now the computer is far far away from my reach, but when I configured the system I noted that whenever I was locally logged to B and then ssh'ed from A to B, I was logged in without any problem; whenever I was not logged in locally I was asked for a password. Note that at that time I was using a different public/private key pair whose private part had no passphrase.
how to know exactly what cipher is ssh/sshd using for a particular session? Is there a way to know any statistics for a given session (something like the ~s option in section 5 of [URL]
P.S. 2: does the following mean that ssh is using protocol 2.0 or something different than protocol 2.0?
(..........) sshd[2606]: debug1: Enabling compatibility mode for protocol 2.0

In order to push, I need to do this:eval ssh-agentssh-add ~/.ssh/github_dsaThis is driving me nuts that I have to do this every time. So, I just put it in my ~/.bashrc file. I feel like that's a hack. Is this normal?

I have created a public/private key pair to connect to the remote server without using a password. I have also been able to use this key pair to login from the command line: sftp -vvv -oPort=<server-side port> user@server.Debug info from interactive command:

I'd like to ask one simple question I can't figure out how to solve.I've set up my public key authentication by generating the public key on my Windows box. Copied that into /root/.ssh/authorized_keysDisabled password authentication in /etc/ssh/sshd_config:
#Port 22
#Protocol 2,1
Protocol 2

I often run into this and it's such a hassle that I have had no choice but to ignore it. But, I would like to run it properly but I don't understand why my sources list is 'wrong' or has incorrect info so that it's often not verified or authenticated. The public keyring is wrong or the source or both? I get these messages, for e.g.:
# apt-get update && apt-get install dmo-archive-keyring && apt-get update exit with result:
W: GPG error: http://unofficial.debian-maintainers.org squeeze Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9EEBC8DB9B9C3CB6
I probably don't need that but I ran into a similar error trying to authenticate the multimedia keyring. Not sure it worked but I am guessing the system works the same with all the authentications? I hope to understand what I'm doing wrong and what the process is.
I'm trying to connect to my Xubuntu box (zelda) remotely using my RSA key. I'm using Cygwin on my Windows box (link) to SSH in to the Xubuntu box. I've created the key and placed it in the authorized_keys file on my remote box. Here's where it gets weird. When I ssh into zelda the first time, it prompts me for my password. However, if I'm already connected to zelda and try to open another connection, it prompts me for my RSA passphrase. This is very confusing, and I have no idea what's going on.Here's my sshd_config file on zelda.
Code:
# Package generated configuration file
# See the sshd(8) manpage for details

Im trying to create a public/private key for open ssh, I don't really know what difference between the two. I want it to all be one command and not have to hit enter after each command. Here is what I mean:i type "ssh-keygen"and it asks me were to save, then my paraphrase, then reenter the paraphrase.I just want to be I guess you could say unattended if that makes any sense.
View 1 Replies View RelatedAfter years with Linux and using ssh on a daily basis I have to admit I've never setup public/private key authentication and I've never run passwordless logon to ssh. It's not that I've never tried, I have - I've just never got it working. That to me is an almost alien concept as I am a tinkerer at heart and rarely stop until something is working the way I'd like it to. I get the principle of what's going on but I've always had a mental block about it.

1) it does not send emails to a certain domain, unless i do dpkg-reconfigure on exim4 and put the domain on allowed relay... can't i just put something on settings which allow to send emails to ALL domains?
2) EVERYONE can connect to the server by telnet from any position, terminal or pc, and just use an existing user to send emails to anyone.... example, i have testuser123 setted up in debian/exim4 .. then they simply write "mail from:testuser123@host.dot" and the server accepts it.. without even request an authentication for that. And this is a problem, because everyone can use my email addresses to send emails to whoever.. heaven for spammers/hackers..
So after tinkering for a while, I was able to configure ssh for private/public key authentication and disabled Password-Authentication. In the past I had some issues with people brute force trying passwords/usernames so I want to avoid this, but I need some form of secure FTP that now doesn't work due to the aforementioned setting.

I'm trying to restrict command line ssh and yet keep NoMachine working, so I followed this post [URL]... and tried adding this to /etc/ssh/sshd_config:

I have trouble with rsa authentication:
I did create an rsa certificate with ssh-keygen using my root account on a client: ssh-keygen -t rsa -b 2048 no passphrase I did copy the rsa pub_key from my client to the server scp id_rsa sampleuser@sampleserver:/home/sampleuser/.ssh/authorized_keys
I did change the ownership to the "sampleuser" of the pub key file on the server: I trayd to connect:
ssh sampleuser@sapleserver
I get that: permission denied (public key)... I know I do smth wrong but I don't know what.
I am trying to install openssh server with public key authentication on CentOS.
But i am getting following error message: Disconnected: No supported authentication method available Server refused keys
My sshd_conf file is as follows:
I run the following file with the >log.log redirector and it does not capture errors.
#!/bin/bash
echo ************************BEGIN LOG******************************

The following errors show up when I run from the file from the term window, but are not written to log.log:
tar: /public/public/clamscans/*.txt: Cannot stat: No such file or directory
tar: Error exit delayed from previous errors
mv: cannot stat `/public/public/clamscans/*.txt': No such file or directory
I know with windows you can add the 2>&1 to capture error data. Is there such a thing for Linux?
I am running LMDE with xfce desktop version 4.8.0 and Windows 7 on a sony vaio. Everything works fine except for one minor inconvenience... When I am using xfce and want to reboot to windows, I have to click shutdown,turn the computer off then back on to get to the grub menu. If I click restart, it reboots back into xfce without ever showing the grub menu.

Everything works from public access until I try to link to a CVS repository. The rancid CVS repository is set up as a separate server (virtualhost). It appears the referring link causes a DNS error (105: Server Not Found) when the CVS repository server is accessed from the public address. Things work fine when accessing via localhost.

I installed freenx-0.7.3-i486-1alien.tgz on the server (with Slack 12.1), all according to instructions. I installed the no machine nxclient 3.4.0-7 on the client (with Slack 12.2). I ran setup and configured. I used the default no-machine keys, not custom ones. Since authentication failed at the beginning, I enabled DBauthentication, and added my user and password, which seemed to allow authentication to occur.
Here is my node.conf:

# This file is provided by FreeNX. It should be placed either into

I'm trying to write a p2p file sharing program using python's built-in libraries. Everything is going well. The only thing is that i'd like to be able to use openssl public and private keys so only a host with the public key could access/decrypt the filesharing. I've gotten these libraries (httplib, basehttpserver, ssl, os) to work using just a pem file containing both the public and private keys but no success with them seperately. Can someone point me in the right direction or offer an alternative? PS, the goal of the project is to create an anonymous, decentralized, secure file sharing program. I want to be able to upload this to sourceforge so everyone can use it, if that's any incentive

So I recently upgraded from 9.04 to 9.10 and then to 10.04, and I love it!
But there's only one key problem -- sound playback.
When I'm playing an mp3 file in rhythmbox, or any other player, it'll skip when I maximize or minimize windows, or do anything that really uses resources.
And on top of that, if I just let it keep going, it'll eventually just stop playing the song, and the progress bar will jump forward and do the same for other songs, not even playing them.
even songs on pandora.com skip, but don't stop playing
I've deduced that it's probably a sound driver thing. I've downloaded the driver for my card, but I the directions tell me to install it in
/usr/src/linux/driver/sound
I've just bought an Asus U31f and installed openSUSE 11.4 64bit on it.
There are no problems with the mouse and mousepad at first when I boot up, but after a while it starts to skip and jump around, and will hardly move vertical at all (allthough it is very eager to move sideways).
The touchpad also becomes overly sensitiv, as I can move the arrow from side to side while holding my finger 0,5 cm above the touchpad, as seen here: [URL]
The weird things is that it can work fine for several hours, and the suddenly turn evil.
In the sound preferences if i set the sound to ALSA sound skips like a scratched CD when i move, maximize, open, close window. If i set the sound to PulseAudio sound skips on everything (vlc ,banshee)except Totem.
On both of these options Banshee is rendered totally unusable. If i set the sound to ESD, than VLC and Banshee work fine though VLC still skips a little bit though less than before. Totem however will no longer be able to play most of the files it could before without extreme unbarable static. Though some files it will still play fine.
HOWEVER with all three of these there is no skipping whatsoever when i play sound on ..... videos in the browser whereas if i play the same video in .flv on a media player the same problems persist.. so the browsers seem unaffected
OSS is by far the best in terms of skipping, none whatsoever. However OSS has a constant steady crackle behind anything that is playing. The crackle is low but still irritating and the crackling makes my ears ring after but i can still listen to music and just try my best to ignore it much like listening to a radio station that barely comes in. So how do i either to stop the static behind OSS... or stop the skipping with ALSA and Pulse, or stop the crackling in ESD or OSS??
