Debian :: Openssh-server Doesn't Check Into "authorized_keys" File
Jul 22, 2010
I have two Debian 5 servers which running on both the same version of OpenSSH (5.1p1) and OpenSSL (0.9.8g).
One week ago, I set ssh keys on both of them and create the file "authorized_keys". I was able to connect on each server via SSH without password (which is the purpose of ssh keys) but I had an issue with the SSH service and I had to restart one of my server. And since this time, when I try to connect to my other server with the same ssh command, the command ask me to type the password...
This is the result of the ssh command (with the argument -v):
Code:
OpenSSH_5.1p1 Debian-5, OpenSSL 0.9.8g 19 Oct 2007
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug1: Connecting to MY_SERVER [1.2.3.4] port 22.
debug1: Connection established.

Is it possible to 'include' a global SSH authorized_keys file?
For example, I have user accounts user1,user2,user3 and my user name is Benjamin. I want to be able to use my ssh key to authenticate as each of these users. I can manually copy my key to each .ssh/authorized_keys file individually, but is there a way to simply include /home/Benjamin/.ssh/global_authorized_keys in each of these user's authorized_keys file without manually adding and removing?

I would like to recompile the openssh-server with a different version string. I download and compile the source, but so far I have only been able to compile and run the client. Not the server.
Steps taken:
Is there a flag or option I need to specify to insure that it creates the sshd?

I have Ubuntu 10.04 and I used my ssh to connect to a webserver. This is the version that I have installed.
Quote:
OpenSSH_5.3p1 Debian-3ubuntu4, OpenSSL 0.9.8k 25 Mar 2009
Apparently the server was hacked using my user and the server admin suggested the my ssh can be tainted.
do a checksum of the ssh, but I cannot find this file on my system.
Code:
md5sum /usr/sbin/sshd
And I will need a md5 hash from a good untainted version and I cannot find that as well on the openssh website.

So this very (for me) important little package fails me once again. But this time it refuses to restart/start
This is the output:
Setting up openssh-server (1:5.3p1:-1)
Restarting OpenBSD Secure Shell Server: sshd: failed!
/dev/null is not a character device!
invoke-rc.d: initscript ssh, action "restart" failed.
[Code].....
The error is within the /etc/init.d/ssh script. ("error")
This is in squeeze so I can only blame my self, but.. This is one of the packages that fair and square should not fail to install/update/start/restart no mather what!

I'm in need of a bit of assistance from you Debian users. I have two servers that I thought were identical installations, both running Debian Lenny. Tonight I started the upgrade to Squeeze on both servers and one of them went smooth. The other one started out good but fails on the postconfiguration of openssh-server. I'm getting the following message:
Code:
Setting up openssh-server (1:5.5p1-4) ...
Auto configuration failed
2524:error:0E079065:configuration file routines:DEF_LOAD_BIO:missing equal sign:conf_def.c:366:line 67
invoke-rc.d: initscript ssh, action "restart" failed.
[Code].....
It looks like there's an error in one of the files in openssh-server that prohibits it from installing correctly. However on the other server it all went well.

I maintain my slackware by using slackpkg-current. When I upgraded to the new OpenSSH 5.4, I noticed that my key method (passwordless) doesn't work anymore. I checked and checked the conf files but everything looks fine.I tried debug but can't get it to work, here is the debug:
Mar 15 21:52:15 vmslackware2 sshd[2663]: debug1: rexec start in 5 out 5 newsock
Mar 15 21:52:15 vmslackware2 sshd[2622]: debug1: Forked child 2663.

I run a few virtual servers at home behind a NAT, including an e-mail server, with dynamically updated dns records pointing to each of the servers. Consequently, I suffer from the loopback problem when working with these servers from my desktop PC. (E.g., I ping one of the dns hostnames and the ping goes to my router instead of the server). I fixed this problem by manually adding the in-home IP addresses and name pairs to my /etc/hosts, and then setting /etc/host.conf to a "hosts, bind" order.
This seems to work for every application on my desktop except for one: the postfix installation on my desktop PC (used for mailing smartctl messages and so forth) cannot communicate with my in-home e-mail server (times out). I checked the logs, and it looks like it is trying to use the IP address from the actual A-RECORD, rather than the address in my hosts file.
So I'm not quite sure what to do. There seems to be a "proxy_interfaces" parameter in main.conf which might be relevant, but I think it only deals with received mail. I'd prefer to have the mail going to that e-mail server, rather than also having to check the spool on my local desktop accounts.

I have configured openssh 5.8p2 with centos 5.6. My sftp is working fine with chroot environment but i am having problem with SCP. I am dealing with muliti Redhat servers. When i try to transfer data from other linux server through scp it gives connection refused. For e.g ssh 5.8 is configured on new server and i want to transfer files from old server which is using openssh 4.3 version.i created same username and password on new server as on old server.My sftp users on new server has no shell access but only sftp access. When i try to scp from old server to new server it gives error connection refused. Is the below configuration only for sftp and can't scp? According to google the configurations i found are for scp and sftp. Do i need to generate ssh keys by giving users on new server shell access, once created then stop shell access again, as i dont want to give shell access permanent for security reasons? but i want to use ssh keys for more security as well.

I've created a new group and a new user called dftp... Now I wanna do one thing... If 'dftp' connects thru ftp he should be directed to a particular location... and he shouldn't be able to see other folder except for his own including the parent folder that contains that location... I changed dftp's home folder to the location I want. However while connecting thru ftp. user dftp has been given permissions to see other folders and check out the contents of the other folders.

I need a script that dose the following checks if files exists by read input from a file then compares them to the files listed in the directory if they don’t exists the script would report back which file dose not exists. I also need to format the output so that files are grouped in different groups, group A, B, and C and etc based on file name. I would like the output of that do not exists files to be sorted based on second number in the file name than group according. I understand some of the basics of bash scripting something along of the lines of a loop and if statements might do the trick. Below is what I have so far. I don’t car so much about the script reporting back the file exists I prefer to only know if the file is missing and is less than 3 days old. Problem is if a file dose not exists in the reports file the test compares against the wrong file.
Group A
Foo22000.tar.gz
Foo22010.tar.gz
Group B
foo25000.tar.gz
foo25100.tar.gz
Group C
foo26000.tar.gz

I have a RHEL server with users logging in via ssh. I want to start using public keys instead of passwords with ssh. But public key is as good as a rotten tomato if it is unpassphrased and I cannot guarantee that all users will use passphrases. Therefore I will generate both private and public key on the server and will distribute the private key to the user via user-friendly web interface and thats where I will force them to use passphrase. I know they can change later the passphrase or remove it totally but my users are not so advanced.
So now I am trying to setup a centralized authorized_keys file with to be able to make them only root writable so they cannot put their own public keys on the server , it will be handled by scripts. Now the actual problem. I created /etc/ssh/keys directory instead of ~/.ssh and changed AuthorizedKeysFile to /etc/ssh/keys/%u in sshd_config But when I try to connect with the key I get the following error in the logs (after enabling DEBUG3 in sshd_config)

When I connect with my vps server through openssh, doesn't establish connection. Openssh is active (see its status), port 22 is open, the sshd_config file is the same of original copy (I have saved one in the case I did a mistake) the only line different permitrootpassword is set on ''no'', there isn't a firewall that block ssh connection and with other remote desktop control like remmina works well.

Whenever my debian based server is rebooted 35 times it does an automatic disc check. When it does this and completes the disc check it doesn't properly establish network comms and I can't get in using SSH and I can't even ping the server.If I reboot again, it operates as normal but the problem is that the server is remote to me and I need to travel to the site when this occurs.

I'm having problems getting openssh server to accept connections in Ubuntu 10.04.Here's what I've done (twice): Installed Ubuntu 10.04 on USB drive with pendrive installer. This creates a default user "ubuntu" and you don't get the chance to choose a password for it. Started a keyring for network access and selected password. Works.Enabled VNC and selected password. Works fine with VNC client on local network. Logs in as "ubuntu" user and asks for the VNC password, then connects. Note: the client doesn't know the "ubuntu" user password, and neither do I! However, it works.Installed openssh client and server from Ubuntu s/w center.
$ ssh localhost OR $ ssh ubuntu@localhost try to connect, but asks for password, which I don't know (see step one, above) so, then I created a new user, with known password, logged in as new user in Ubuntu, works.however, $ ssh newuser@localhost still fails, even when correct password for <newuser> is supplied. Rejects the password three times, then gets the usual error about keys.I also tried connecting with an SSH terminal app from my iPad, again using <newuser>. It gets essentially the same error, "failure to authenticate".
All this is still on my own LAN, haven't gotten to going outside the router yet.What I want to do in the end is use VNC over SSH from a client on my iPad to talk securely to Ubuntu while I'm traveling.

I have recently discovered the following: when I attempt to connect to any of our machines that are OpenSSH 5.x (Ubuntu 10 or OpenSuSE 11.x in our case) as one of the users defined in the NIS domain that fails. For instance, me (user bepstein) can SSH into all those machines but not SFTP.I can SFTP into those machines on the network that are OpenSSH 4.x, however (CentOS 5.3 - 5.4, OpenSUSE 10.3).As a user defined locally on the machine (in /etc/passwd ) I can connect via either SSH or SFTP even if the machine is OpenSSH 5.x.Some further discussion of that issue is available here: http:[url]....

I have an old computer a friend of mine found in a dumpster, and I've decided to use it as a file server. After finally getting it to connect to my wifi network, I tried connecting to it via OpenSSH on my main desktop. After I connected, I noticed OpenSSH was being very laggy. Whenever I type anything in there's a very noticable and annoying delay from when I type it to when it appears on screen. Now, a while ago a friend of mine was helping me fix my laptop when fglrx drivers broke x, and I set up openssh on there so he could access it. According to him, there was no lag (and he's half-way across the globe, whereas my file server is in the other room). The computer is an old Pentium 4 with one and a half gigs of RAM, two hard drives (one I use for the os/swapping and the other I use for /home). It's connected to wifi via a spare USB Linksys 802.11 bg adaptor I found lying around, and it's using the default drivers that come with Debian to connect.

I have VNC working but I like how freenx starts in it's own session. It is handy for when my account is not logged into the server and VNC hasn't started.I have freenx working but it requires sshd_config to enable PasswordAuthentication. This isn't a major security problem at the moment since I have deny.hosts running but I still don't like it enabled. I would much rather only use the keys.

My Fedora Core 8 server came with OpenSSH Server 4.7p1 installed. I could not find a YUM package or RPM for 5.2p1, so I installed it manually and rebooted. Now if I do a version check with "sshd -v", it reports it's version as "OpenSSH_5.2p1", but if I connect with Putty, it reports "SSH-2.0-OpenSSH_4.7". Do I have two versions of OpenSSH running or what's going on?
