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 RepliesI have this very weird problem: I'm not able to SSH to 1 specific server on the web. I can access everything, but not that specific server.
When I try to SSH, I get this code...
When I reboot to Windows, I can SSH using Cygwin. I'm using Ubuntu 10.04 Lucid and OpenSSH client 1:5.3p1-3ubuntu6.
I tried sniffing the network with Wireshark, but I cannot understand why the TCP connection cannot be set up. I'm sure it's an Ubuntu problem as I'm able to connect to that server on the same machine, but different OS.
I 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.
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'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.
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]....

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?

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 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.
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 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:
F12 64bit
Debian 5.0 64bit
Openssh
Both openssh-server and open-clients are running on 2 boxes. On F12 it is named openssh-clients but on Debian 5.0 openssh-client without "s".
1)As root both boxes can connect remotely another box.
2)As user both boxes can't connect remotely another box.
I'm trying to get OpenSSH public key authentication to work. My server runs ubuntu. My client is a windows machine, and I'm using cygwin. I tried using the instructions here: [URL]... If I test it out using this line: ssh -v -v -v -o PreferredAuthentications=publickey server.example.org
I get this:

I now have my ssh server all setup on my ubuntu 10.10 machine and properly working with a private rsa key. Anyway when I connect to it via my client it opens to: /home/myusername
I am able to run around the whole drive and have full access to everything, which is great. But I don't have anything on this hard drive. All my data and files that I really want to access are on the second drive of this computer. It doesn't have an OS on it, just files.how to change the directory to point to that drive and have full access of everything.
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:

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 am running Ubuntu (Karmic) and did the command: "sudo apt-get install ssh", In an attempt to download, install and setup OpenSSH. This installed both the client and server and during setup actually brought the daemon up and running as well. I then attempt: "ssh <myusername>@localhost" and it prompts me with a password. I enter the password, hit enter and immeditaly see the following results:
Read from remote host localhost: Connection reset by peer. Connection to localhost closed. I'm fairly certain that it is not on the client end as I can connect to other machines through ssh. I've tailed all the logs, messages, dmesg etc and nothing seems to be out of order, or even remotely related to shh or connections etc. My desktop machine had no (as in zero) issues installing and setting up OpenSSH, and connections can come and go as normal.
In Gnome Places->Connect To Server dialog, I am having problem using the Custom Location Service Type. I enter in the URI as
Code:
smb://username:password@ipaddress/share_name
I get an pop up error message that says:
Quote:
Cannot Connect To Server. You must enter a name for the server.
Which would be fine if there was actually a place for me to enter the name which there is not. What am I doing wrong. This is the first time I have tried using the Connect To Server dialog. Normally I just use a script I wrote to mount my share in a folder on my local drive as some programs cannot access the mounted network folder. In a browser all I have to do is:
Code:
smb://ipaddress/share_name
I tried using Windows Shares, but that did not work either. It does work if I click on network and access the share that way, but some programs like firefox and a few others that I want to save a file to my network drive do not show the network unless the share is mounted in a folder. So, I wrote a script:
Code:
#!/bin/sh
#mount ext storage drive
mount -t cifs //192.168.0.2/files -o username="username",password="password" /mnt/files
This works and I can use this, but it would be handy if I could just use the Connect To Server dialog.
I need to connect with a server apart from the server which I work on. What is the command for this?
View 5 Replies View RelatedI 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:

View 1 Replies View RelatedI set up 9.10 as a file server at my house, connected through the router via LAN. I had everything working, using it as a Samba file server. I moved to to my college apartment and I am now having troubles... I changed the network information in /etc/networking/interfaces to what it should be (or at least I thought so...)
I can ping myself, but nothing else. Also, on my router configuration page, the server is coming up as a connected device with the correct IP address that I set it to.
My problem is that i cannot connect to anything that is running on this server via WAN. i can connect to everything from anywhere just fine through LAN though... i have all in use ports opened up on my router. i tryed messing with the ubuntu firewall and even tryed turning it off. but no luck. btw i am running ubuntu server 10.04 with matching desktop!
View 5 Replies View RelatedI just loaded NX Server, following the instructions from NoMachine. When I try to login from a client I get "Authentication Failed for User My Username" I can use the same client to connect to another NX Server on my network so I know the client works. I'm not clear if I need to set up a user, or if I can just logging with the username & password from the host (which is what I'm trying).
