I'm trying to get openssh-server working so I can stop using the family TV and just SSH from my laptop. I've only just installed 10.4 server edition, and I've made a change to /etc/apt/sources.lst by removing the # in front ofdeb cdrom:[Ubuntu-Server 10.04 LTS Anyway I run:sudo apt-get install openssh-server

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 have an Ubuntu box running server 11.04 that is displaying a weird behavior when logging into the CLI. The message below will scroll for about 15-20 seconds when you first log in, but then it goes to the normal shell and everything seems to work fine.
Code:
Welcome to Ubuntu 11.04 (GNU/Linux 2.6.38-8-server x86_64)
* Documentation: http://www.ubuntu.com/server/doc
[code]....
Main purpose of this LAMP server is testing development. I would like to get this server setup up almost exactly to a T how my real web hosting server is setup. I am running 11.04 and have installed LAMP. I also installed vsftpd. I went ahead and made a symlink from /home/user/public_html to /var/www/. I login from a Windows 7 computer via CuteFTP to my Ubuntu server. I can enter the public_html directory and can create folders but the default permissions for any folder created is 700. I have tried running chmod -R 755 /home/user/public_html but this does not work. Every file or folder created now currently will take a 700 permission.
How do I make it so anything that is uploaded into this folder will be at either 755 or 775? Also what is the best practice for utilizing the /var/www directory? Should I be using a symlink to link it to my user's home folder? I have read through so many posts with regards to adding users to a group and giving this group permission and this or that I'm so confused.
I have two ubuntu boxes. One is a 9.04 desktop edition and the other is a 9.10 server edition I am working on some code that needs to be highly tolerant of bad network connections. It sends transactions to a central database, but when the network is not available, it caches them locally to retry later.
I have the code working beautifully on my desktop box. but when I test it on this other box (the one running server edition) there is a HUGE DELAY every time it tries and fails to send a transaction to the database when the network is down.
I tested a little further, and I found that if i unplug my network cable and run ping somehost on the desktop, it fails instantly saying "ping: unknown host somehost" But if I unplug the cable on the server box and run the same ping command it lingers for about 40 seconds before the ping fails.
Does anybody have any idea why this might be happening? Is this a 9.04 vs 9.10 difference? Is this a desktop vs server difference? Is there some package I can install, or some config setting I can change that will make the server box insta-fail just like the desktop does?
A week or so ago I ran an aptitude safe-upgrade and while it was updating mysql I suffered a power-failure. Now, this never really happens in Holland but of course this once it happened at the worst possible time.
I've tried a lot of different things to get mysql working again, but am running into all kinds of problems. First mysql won't shut off properly (it does startup with the computer but I can't connect to it at all) during an aptitude purge. If I kill the process mysql seems to purge properly, but I guess this is not the case because I wasn't able to install it then.
Things seem to have gone a bit more smoothly this time, however:

When ever I try to sftp or even ssh into my server I get connection refused.
I have the port forwarded in my router.
What am I missing?
Also I have installed Ngnix so what do I need to do for it to work?
I would like to upload files via ftp or sftp to my web directory at /var/www/...
Originally I had installed openssh-server (through apt-get, before learning about tasksel). I assumed this only had ssh support and not ftp, so after a quick search, I installed vsftpd. I would like to learn how to configure openssh, and I mention vsftpd in case there is a conflict.
Right now I am able to log in to my server box through ssh/ftp, but I can only modify my home directory. I created a directory: /var/www/andrew and set permissions to drwxr-xr-x. I am unable to upload files to this folder.
What do I have to do to resolve this, and is there anything else I should know about my situation?
I'm running Ubuntu 10.04 LTS and I have installed openssh.I need to find a way to configure it so that it never start up when I boot into my computer. The reason is: I haven't had the time yet to learn how to set it up and configure it correctly. Until that time comes I don't want it to run at all.Every single time I boot into the system and I have to do that first before I can even do what I really need to on the computer. It's annoying.Does anyone know the best and least complicated way to just make it not run at all until I'm ready to set it up properly?Also how to check what is running on my system after I boot up so I can double check, after making the changes, that it worked right.
View 9 Replies View RelatedLike many others I'm running into some reverse lookup issues with SSH. Setup is as follows:
localnet setup
myserver - 192.168.0.x
myworkstation - 192.168.0.y
[Code].....
nslookup tests show that my reverse lookup is functioning correctly. However, if I use "myworkstation" to connect to myserver.mydomain.com using an external nameserver SSH says: "Address 84.162.xx.yy maps to myserver.mydomain.com, but this does not map back to the address - POSSIBLE BREAK-IN ATTEMPT!"
On myserver the /etc/hosts has the internal address for the server which seems the normal way to go to me. Changing this to the servers external address solves the issue.
Apparently a connection originating from myworkstation arrives from/with my external address, and when its reverse is checked by the server it apparently finds its own internal address for that name in /etc/hosts before doing a nameserver query and thus concludes that internaladdress <> externaladdress which gives the error.
Is there any way to have the server check external DNS before /etc/hosts? Another solution would probably be running an internal DNS, so myworkstation doesn't connect through the 'outside'.
I'm new around here and pretty new to ubuntu and linux in general. I am setting Up an sftp server. I set it up using openssh and it worked fine for a few months. Then recently we experienced a power outage. Now the server will boot fine, all users can login locally, but when they try to login remotely they enter their user info and then are denied with some generic network error. Again, being a noob at this I tried to trouble shoot this a little bit but I'm not quite sure what to look for. I believe the ssh service is running but I don't know what else to look for.
View 9 Replies View RelatedI would like to replace default OpenSSH version 4.3 with latest one (5.x). New version do support SFTP chroot, which is something I need.Of course, it can be compiled from source, but it is worst possible option for maintenance, since I do have few servers. Does someone provide RPMs or source RPMs at least ? If yes, what is repository/URL ?

View 2 Replies View RelatedI 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'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.
Changes I've made to the config files:
Connecting with PuTTy works fine with my public/private keys. But why does sshd start and then restart twice when booting? I tried looking in the logfiles under /var/log/ for anything with ssh/sshd but nothing shows up.
Ubuntu Server 9.10
I connect to a server on linux(openssh) through ssh. Is there a way such that i can hide my IP on that machine so that the server won't know my username and IP address?
View 5 Replies View RelatedI have FTPS setup on my ubuntu server 9.10 machine using vsftpd, and I want to disable the default SFTP server in openSSH. I didn't even know it was on until I accidentally connected to it. I tried searching the internet, and it seems that all I should have to do is comment out the line:
Code: Subsystem sftp /usr/lib/openssh/sftp-server restart sshd and it shouldn't work anymore.....except it does. Thinking that /etc/init.d/ssh restart may not have worked, I restarted the machine, but I can still connect over sFTP.
How can i setup SSH server on one machine and openssh client on another machine running suse 10.3
View 2 Replies View RelatedI 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 problem with the config file for clients which is ssh_config or ~/.ssh/config
every config that i write in them not working fore example when I change the escape character to ! its not working or any other config I checked with another system that has the same OS ((debian 6)) but the problem was there too
Do I missing something here that cause this? like enabling client configuration ?
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]....

View 4 Replies View RelatedMy 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?

View 3 Replies View RelatedI need by searching this site so I haven't had a need to sign up since I can't really help anyone as of yet. With that said here is my problem: I'm running a VPS with CentOS RHEL 5 host-in-a-box, I just did a rebuild of the server and after a day or two pure-ftpd and sshd unexpectedly close out any incoming connections. I am the only one that uses ssh and ftp so I'm not sure what the problem could be. I checked the logs and there is nothing to do with not being able to bind on the address.
I tried connecting through ssh in verbose mode and it connects to the server just fine, but drops the connection before it asks me for my key pass phrase. If I enable password access it will drop before it asks me for it's password. I've tried restarting sshd and ftpd. I've tried rebooting the machine. I've tried google, but this problem seems to need a little more specific trouble shooting. I can get in through console access, but that doesn't help me much when I need to transfer files.
I'm running Ubuntu Server 11.04 with OpenSSH, trying to create an ssh tunnel (for web traffic) to it from my (also Ubuntu) laptop. This is the command I'm using to create the tunnel:
Code: ssh -ND localhost:8080 george@192.168.1.20 I had it all working on a virtual machine.. which was deleted What settings/lines do I need to change/add from the default OpenSSH config files to get tunnelling to work? I've Googled and AllowTcpForwarding is set to yes, as is X11Forwarding.. but it still doesn't work. Chrome can connect to the server, but says the connection was closed before any data was sent.
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!
