I have 2 servers A & B. both installed on different locations. both can ping and traceroute each other but there is no load shareing (both performing same functionality but independently). when i checked of server B /var/adm/messages, i can see that server A is trying to connect to server B but getting failed. and this is going on for long time. i mean it's not like someone manually try to enter but automatically its happening. i have already checked in cronjob but there is nothing. here are the logs,

I inherited this shop. NIS is working fine... and has for years with one exception.One user named jpeters (not really ... just made that up) couldn't ssh into the network but she only had problems ssh'ing into one server named frodo (nis client). Other users were / are able to ssh into frodo so I know the daemon is running. (I saw the other thread that sounds exactly like my problem - but the solution didn't make sense because I don't have any other domains. Oh and I do *not* have sldap running anywhere.)When jpeters ssh'd into frodo it failed: "permission denied."Jpeters can, however, ssh into all the other NIS client servers. On the problem box, frodo, if I: # ypmatch jpeters passwd frodo returns the info stored on the NIS Master (gandalf). I verified this from several other servers too. All are pointing to the NIS master.
Then I discover that jpeters also has a local user account on frodo. I deleted (userdel) her from the local users on frodo. While this *did* successfully remove her record from frodo's local /etc/passwd file it didn't remover her from the /etc/group
Question 1: Shouldn't userdel have removed her group entry?
So I then used vi to manually remover her from frodo's /etc/group.But, still, she couldn't ssh into frodo and I'm tempted to tell her to STOP trying to ssh into frodo ..., but then I noticed that, unlike the users that are successful at ssh'ing into frodo, user jpeters belonged to several groups including "wheel." So I changed this in the /etc/groups on the NIS master server so she no longer belongs to the wheel group.She still could't ssh into frodo though. I then ssh'd into frodo as root. and as root I su'd to jpeters: # su - jpeters # yppasswd
but now something is different - I'm jpeters now and I when I entered jpeters password to authenticate the password request change, NIS *did* recognized her password!
I then changed the password and the changes were successful. jpeters can now ssh from all the servers including frodo.
Question 2: Do you think that taking jpeters out of the wheel group resolved the problem? Or did I just forget to make or restart or rebind something...
In trying to troubleshoot this problem I've learned a great deal but I'm also confused because as I said, NIS is working yet many of the things that people in the forum said to check aren't there for example: # ypcat ypservers returns nothing
Question 3) how can this work if ypcat servers returns nothing?
Question 4) why does my passwd file on the nis server contain encrypted password for some users? Most have x in the password field but a few have gobbledgook. All the users that I have personally added appear this way. What am I doing wrong? And how do I fix it?
I want to use nomachine, instead of freenx, and well it isn't working. SSH server works and all, because freenx works., same for neatx. But I hear with nomachine you can see the main display of the computer? Is this true? Well one way to find out, but whenever I try to login I get: Authentication failed for user x. I don't know why, neatx and freenx worked, even x2go, but not this.
I am trying to set up my Ubuntu 10.04 netbook to see my WinXP desktop's files and vice a versa. I followed the steps in this tutorial thread: HOWTO: Setup Samba peer-to-peer with Windows. I got as far as "Time to add yourself as an samba user." at this point I keep getting the following error:
Code: sudo smbpasswd -L -a WinXP_User_Name New SMB password: Retype new SMB password: Failed to add entry for user WinXP_User_Name. My WinXP machine has no password.

I am currently attempting to setup Samba 3 (installed) for a basic home-network file-sharing server via Ubuntu 10.04. It seems like (based on my extensive googling and research) nobody wants or has a configuration like I do, but surely SOMEBODY knows how to do this.
The following is my goal for a basic setup.
Folder 1 (share is called "Read-Write"):
-Users from Windows 7 can see, read, write, execute, create, or delete any files and folders in Folder 1 as they so desire.
-Users can accomplish all of this from as "guest."
Folder 2 (share is called "Read-Only"):
-I can log in as my user to see, read, write, execute, create, or delete any files and folders in Folder 2 as I so desire.
-People other than me can log in as "guest."
-"Guest" users from Windows 7 can see, read, and execute programs as desired.
Things I have accomplished:
-Directories exist
-Directories are browseable via Windows 7
-My user has a password for Samba (assigned via "sudo smbpasswd -a matthew)
Things I have not yet been able to accomplish:
-Configure Folder 2 so that Samba asks for login credentials when someone tries to access it SO THAT I an use my Samba user to log in.
-Configure Folder 2 so that, when I log in as my Samba user, I can see, read, write, execute, create, or delete any files and folders in Folder 1 as I so desire.
-Configure Folder 2 so that Windows 7 users can easily access it as guest to browse, read, and execute files and folders in it.
-Configure Folder 1 so that any Windows 7 user can easily access it as guest to see, read, write, execute, create, or delete any files and folders in Folder 1 as they so desire.
Network server to administer accounts for all users, one login ie at login select or type in user name and password to login - so that I don't have to setup users separately on all PC's so that they can login from any computer.
Have been configuring fedora 14 to connect to a windows domain server and have been successful so far....am now on mapping network drives when the user logs in via the gnome gui.
If there is a better method of mapping network drives on login
After reading up on PAM_MOUNT and using that for mapping drives on login I have been able to successfully map them, but it doesn't do this automatically on gnome login.
Problem is as follows: It works when i connect / login using the terminal but requires me to enter the password once (even when i logged into the user account on gnome).
How I want it to work:I would like the mapping to occur when i login via gnome so that i dont have to open a terminal once logged in to gnome to map the network drives. I would like it to login without having to type the password again as the user is already logged in
I am using the sudo command to log on locally as another user by the following command:
sudo -u theotheruser -s or sudo -u theotheruser sh
As I see it, this initiates a new shell with the mentioned other user.However, this doesn't load that users profile from his home directory.Is there a way to automatically read the users profile when login in with selected command? I am mostely interested in getting a working prompt when logged in.
yesterday I updated my fedora 13 to fedora 14 (on laptop) and today i cannot log in on user. It just go blank for a sec and is back to login.
At text console (alt+ctr+f2/f3) i enter my username and pass it give this for a sec and resets (clean) console username: Name password: last used: [date] login: no shell permission denied
i used unetbootin (fedora 14 netinstall to update) and later i updated 1,5G before reboot (did update that fix, forgot its name tho :s)
I would most likely reinstall everything, but i have some work at laptop and as death-line is near, i would prefer to fix it if possible.
edited: i have installed F13 on unused space, is there a way for me to access and fix it? or at least get some files from there?
I'm seeing really bad user login format under a standard installation and am wondering why ubuntu does this as default. I have noticed that the graphical login for gnome sizes itself to accommodate a user's exact password length. This indicates to me that somewhere on the unencrypted part of a standard installation with user encryption contains at least some indication of the content of the password length which seems a security flaw even if not a complete hole, it majorly reduces the number of attempts a cracker would have to cycle through.
And that's assuming that *only* the length is contained. Furthermore it seems that it would be MUCH better to simply display the number of characters entered into the pw field and allowing the gui to expand itself from an fixed size as the field is filled out so the the user still receives visual feedback for entering characters. Either a simple character count display should be entered into the field or a 10 dot to new line so that one can visually quickly count the number enter by multiplying from a 10base graphical observation.
I have found this link "Login Failed" message when logging in through RDP
I am suffering from exactly these symptoms. Can anyone suggest what the likely cause is? How would that bug/solution relate to my environment: openSUSE 11.3/xrdp 0.4.1-85.1?
And lastly, how can I find out if the update implied under "Additional Information" has happened?
I installed CentOS 5.2 and then run yum update. I configured this server as LDAP/Samba primary domain controller. LDAP seems to be OK and for testing I am able to create users with:smbldap-tools useradd -am usernameI can ssh into the server as root and also as a Linux user which was locally created in the server. But ssh into the server as LDAP user fails (from a Fedora 11 machine) with "Permission denied, please try again", prompting again for password.Some data:
i am using openssh 5.2-p1, i want to restrict user "admin" to login to the server from a specific IP address, for this purpose i have tried the following blocks in sshd_config file.Following is the part of the sshd_config file which i have modified
#The following commands will only allow specific IP to login to ssh.
#AllowUsers admin user1 user2
#AllowGroups
# override default of no subsystems.Subsystem sftp internal-sftp
Match Group sftpgroup ChrootDirectory /home AllowTCPForwarding no[code].....
i want to restrict admin user to login to the server only from 172.16.100.221 IP which can be done by using AllowUser line, but i dont want to use AllowUser line,
I have a network set up that has been working for around a year with no problems but has now developed a login problem. The system was set up with a main server with all users on it and another PC located elsewhere that people could log onto using there personal login and password that then gained access to the account on the main server. This remote PC has now got the problem. When you try to log onto an account it comes up with the message "your session has lasted less than 10 seconds. If you have not logged out yourself this could mean there is a installation problem or that you are out of disk space."
Error message says that no profile for the user can be found and it couldnt create per-user gnome configuration directory. I can log on as root onto the remote PC as it is obviously a local account but all the account on the main server are not accessible. From the root account I can see that the connection to the server is OK and I can actually log into the accounts on the server using the failsafe session so the physical network is OK.
I never built or designed this set up and to be honest I normally work with windows so its all a bit strange to me. Both PC's run Centos 5. I have checked the messages log and there doesnt seem to be any indication of a problem. Just that it stopped connecting from the remote PC. The accounts are all active on the main server itself and have no problems being accessed.
Is it possible "reset" all (X, GDM related) permissions/settings of one user? What would cause one specific user not to be able to log into anything via gdm/the login screen? After providing the proper password, the screen goes black and then jumps back to the login screen. No session alternative works, not even xterm or gnome failsafe. I can however log in via the console (Ctrl+Alt+F6, recovery etc). With another user I can log in via GDM just fine, and deleting and re-adding the "broken" user doesn't make any difference.
Some (maybe) relevent logs:

I am trying to authenticate against an LDAP server using PAM. I've gotten it asking the LDAP sever if the credentials are OK, but it still fails the authentication.

I found a problem where I least expected it. I cannot use skype on my ubuntu hardy. I install it without a problem, but when I try to login it says: login failed, multiple instances may exist.
After some googleing and several different installations I am still no closer to finding out what is wrong.
If there is anyone with the solution please let me know, and if you need any extra info or command output I will send them asap.
I have configure the virtual mail server both in vexim and postfix .But when i tried to configure the email client on thunderbird and evolution i get login failed error.I am using courier imap for pop3 and imap authentication.

I'm asking this in the right place. I'm using Ubuntu 10.04 LTS and recently started getting a pop-up similar to the following at every boot up: Login keyring failed Your login keyring did not succeed. Enter login keyring here: That's not [exactly] what it says, but very similar. I should probably add that I have not set up any different 'user profiles' or whatever they're called, but am the only one using this PC...at least, at the present time. Again, this only started a couple of weeks ago and I don't know what I did to start it nor what to do to stop it. I guess it's not extremely painful to have to type my password in every time, but a PITA nevertheless.
Whenever I try to install Xubuntu onto my really old computer (not this one), it goes to a screen that shows nothing except the Xubuntu logo and the name. After a bit, my monitor falls asleep, and I am unable to wake it back up.If I press enter while at this screen, it brings up the error message in the title. The same thing happens with all the options I try to press.
I just finished following the instructions found here to install FreeNX on my ubuntu 10.04 server. It went smoothly, just used the default keys.Once I had that all set up I scrolled down and followed the instructions to set up the client and that went fine as well.My problem is with actually using the program.When I try to log in I get the error "Authentication failed for user tony" (my username). Do I need to change anything in the configuration other than setting it to use gnome and putting in the host address?oes it make a difference that my ssh settings only allow rsa login? I logged into the server with ssh to see if that helped but it did not. I even tried using the ssh key with the FreeNX Client but that did not work

I recently installed Kubuntu 10.04 Lucid Lynx Desktop 64-bit edition. The install worked and I was able to restart the machine no problems. Last week (5/27/10) I shut down my machine and since then I cannot boot. I assume it's because of new software maybe a new kernel; I did an "apt-get update; apt-get upgrade" on May 28th or 27th. Upon booting if I hit Esc right away I see:
(process:325): GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0) [About 5 minutes passes then this next line prints] BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu11) built-in shell (ash) Enter 'help' for a list of built-in commands. /bin/sh: can't access tty; job control turned off (initramfs) [this is some kind of shell...who can't see my harddrive]
