Red Hat / Fedora :: Receive Error Code 255 Using Passwordless SSH?
Jun 14, 2011
I am trying to set up passworldess login - I am trying to automate ssh to use send commands from a Red Hat el5.2 server to a solaris 9 server (I did get it working from solaris 10-9).I have ran ssh-keygen -t rsa and then the ssh-copy-id and i can login passwordless via ssh. N HURRAH
Unfortunately when I use my scripts to automate the commands I ALWAYS receive an "Error Code - 255" - the command is successfully sent.

when I connect my iphone (3GS, 4.3.3) to Fedora 15 it gives me this error: Unable to mount iphone
DBus error org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus). The weird thing: after looking in var/log/messages it appears that it is trying to be used by NetworkManager. And when I lookin NM, i can see iPhone as an ethernet device (cable unplugged).

It's been awhile since I posted anything which is a good sign my install has been working well and I have been able to handle most everything. However, I'm not able to handle this issue. I recently installed F11 and everything went well. But, when trying to see my other computers on the local network, I cannot. I receive this error message: Unable to mount location Failed to receive shared list from server. I understand the message as it is obvious, but do not know how to fix it.

How can I configure ssh to do the passwordless logins between the users in a Linux server?I am using RHEL4.6 version. I have created some users in this server and I would like to login from one user to the other users in the same server without a password prompt by using SSH. I was using rsh for this purpose before, but since it is against our security policy , I have to switch to SSH.I have done the ssh configuration by creating the keys and copying the public keys to the file .ssh/authorized_keys of the other users in the same server.But unfortunately still I am not able to login to other users in the same system WITHOUT a Password.I did the following settings.From user1:
mkdir ~/.ssh
chmod 755 ~/.ssh
/usr/bin/ssh-keygen -t rsa

I just completed migrating a Redhat 9 server to new hardware and a virtual machine. If I attempt to alter the time or date with the date command I receive the following message. "date: relocation error:/lib/tls/lib pthread.so.0: symbol __resp, version GLIBC_PRIVATE not defined in the file libc.so.6 with link time reference"
This also comes up during the bootup process along with "sleep: relocation error". I have never done I migration like this before and would consider myself a novice to linux. This server runs an old software package and I would prefer not having to totally reload it. The software we run appears to be run fine at first glance but I don't want to roll this out until all errors are resolved..

I have a server with Fedora 13 with which I would like to get NFS working. I have looked up multiple howto's and tutorials, but I'm having a problem not addressed by any of them.Official how-to, another how-to, and another how-to.I have verified that nfs-utils, nfs-utils-lib, portmap, and system-config-nfs are installed and running. I have verified that I have, in fact, shared the directory that I want to share, and that the proper permissions are set.
I had to go through some gyrations to get the Belkin wireless N router to allow my server to have a static IP. However, I can ping the server from the nfs client (a toshiba satellite running mint 8), and vice versa. I have (for now) disabled firewalls on both computers. I think I have disabled SELinux on Fedora 13 (for now).When I attempt to connect to the server from the client, the output looks like this:Quote:
aragorn ~ # mount -v 192.168.2.101:/test /home/kelev/test/
mount: no type was given - I'll assume nfs because of the colon
mount.nfs: timeout set for Sat Dec 18 12:21:09 2010

If I have a hard-disk with Ubuntu fully installed on it and I want to - all of a sudden - use Windows XP, is it mandatory that I firstly format the hard-disk first? So far, I have used two versions of Windows XP; one of them is from a few years before the other. Both copies of Windows XP when in start-up from booting from CD are causing errors. One of them is a BSOD error (0x0000007B) and the next Windows CD is stopping and giving me an error with setupdd.sys (error code 4). Is it required that the hard-disk is formatted before you even put a Windows boot CD in?

We have a sever on which we made an upgrade from Ubuntu 8.04 to Ubuntu 10.04
We use telnet to access from one local machine to another in our local LAN, but after the upgrade, when we try to connect to our server from a client on LAN we receive the following error:
Is there any known issue about problems in telnetd and Ubuntu 10.04?

Since upgrading to 11.04 yesterday, nauilus has been acting strangely. It takes about 30 seconds for a right click on the desktop to respond, whereas before it would've taken 1 or 2. Also, when trying to open a directory, say, the Home direcotry accessible from the launcher,it takes about a minute to open, which is odd,because all of my other applications (Chrome, Banshee etc) ares all running smoothly. And when the direcotry windowe does open, within 10 sconds it will turn grey and prompt me to force quit. When i try to open nautilus from a terminal, it comes back with the message
Code:

I'm trying to sync a folder between my Windows install and my PCLinux install. Same machine, Windows 7 on the C drive and Linux on an external USB hard drive.
Using the Grsync GUI, I searched for the source and destination folders, and then executed the command. Here is the output:
** Launching RSYNC command (simulation mode): pkexec rsync -r -n -t -v --progress -s /media/Win7/Documents and Settings/Paul/Application Data/The Word file:///root/.wine/drive_c/Program Files/The Word/myData
ssh: connect to host file port 22: No route to host
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: unexplained error (code 255) at io.c(601) [sender=3.0.7]
Rsync process exit status: 255
It seems to be doing an FTP operation, whereas all I need is a file transfer. Can anyone point out my error here?

Using arecord works perfectly with hw:0,0. I had also tried to use /dev/snd/hwC0D0 as input but I receive an error from alsa saying that it doesn't exist (despite it existing and having adequate permissions). I know absolutely nothing about hardware but am comfortable around the command line

I am trying to run OpenNebula on a set of 2 machines. One of the machines(called host1) must be able to access the others(including itself) with passwordless ssh.Both machines have the same user and use mounted folder from host1 for home directory(exported with NFS). So single key generation should be enough for this configuration - all the machines have access to the same .ssh folder.What I am getting at the end is passwordless ssh from host1 to host2 which is great, but no success from host1 to host1. Host2 to host2 is also OK, host2 to host1 wants password like host1 to host1.Both machines have the same sshd_config and ssh_config files.File permissions required by ssh should be correct since it works for host1 to host2.The only difference(I see) between the machines is that host1 runs nfs service, so host2 has access to the exported folders.
The ssh-keygen is executed on host1authorized_keys has the same public key two times(to authorize access for host1 on host1 and host2).The distro is Scientific Linux 6.0 aand I also use rsa.Something else - no pass ssh with another user from host1 to host1 works, so I suppose the problem comes from this mounted folder.

I'm working on some code from my computer at home and would like to do CVS updates to a remote server. When I'm at work I don't need to type in a password, but at home each time I need to type in my password each time I do a CVS update. I've followed the instructions here on how to set up a passwordless public/private ssh key pair: [URL].. However, after that I still need to type in my ssh password each time I do CVS update (or anything CVS related) from my local computer.

I followed the steps here: [URL]
It works fine, except every time I try to do something that requires authentication of the key, I have to type in the password in a prompt that looks like this:
Code:
$ git pull
Enter passphrase for key '/home/<user>/.ssh/id_rsa':
remote: Counting objects: 16, done.
remote: Compressing objects: 100% (9/9), done.
remote: Total 9 (delta 7), reused 0 (delta 0)
...
This is very annoying. How can I have it so I don't have to enter my password each time?
On my local machine I followed the same instructions and don't have to enter the password every time...

I have for a while been trying to setup ssh so hadoop can ssh without a password to all it's nodes. (Currenly 2 nodes)But i can not get the ssh to login without either asking for a password or just getting access denied (public key)I have been following two guidesFirst:Setting up SingleNode ClusterThen after:Setting up Multinode ClusterI have also done various ssh tutorials on setting up ssh.I got to the point where i do the command bin/start-dfs.shThen it begins asking for passwords. Which it should'nt.The problem is that ssh is not setup correcly.And whatever i try i get problems with logging in.the computers are called.
