I have a very peculiar issue - I can't log in to KDE as one particular user (andrew, which is my regular account) though all other users including root, mythtv & other family members can log in without any problem. When I try to login as andrew the X server appears to crash as the screen goes blank and I have to press Ctrl+Alt+BkSp to get back to the KDM login screen. The proximate cause seems to have been updating KDE to 4.4.5 using yum - I did this logged in as andrew in a terminal session using su - root, and the black screen problem arose next time I tried to log in.
I can log in OK as andrew using a different desktop manager e.g. Sugar. I am using radeonhd graphics driver; if I change to "vesa" in xorg.conf I can log in OK. If I change the home directory for andrew to that of another test user and change the file ownerships, I can log in OK. Therefore the problem must lie in a config file(s) somewhere in the andrew home directory tree, which is specific to KDE and also radeonhd. I have checked in all the obvious (and unobvious) places but can't find anything. There are no relevant SELinux errors or entries in syslog or Xorg.0.log. The .xsession-errors file from a failed login attempt is here [URL] it isn't significantly different from a normal one, and as the entries are not time-stamped I am not sure which ones arise during the login and which when I restart the X server. I am running F13 (kernel 184.108.40.206-147.fc13.x86_64) without any other significant issues.
Can advise if I want to have a alert message when a specific user is login to the system , what can I do ? that mean if a specific is login to system then send me a alert message ( by any way ) to inform me the user is login , what is the method ?
How can I enable "Auto Login" for root user?In " Yast --> Security And Users --> User And Group Management --> Expert options --> Login Settings " is just my own user and there's no root user to choose.
Having installed Debian 7 on an old machine from a Liinux Format Magazine DVD I was unable to log in as a specific user. I can login as root and use useradd etc but when I logout of root I still cannot login as a user and nor will the machine accept my root password. I have to shutdown and reboot to get back into root. I'm using O'Reilly's Linux Pocket Guide from 2004 for the commands. Could it be that things have changed?
How do I give permission to a logged in user to stop/start a specific service without entering a root/sudo password? So they can do a simple "service SomeService stop|start" It is for a headless Ubuntu server.
my system I want user1 and only user1 to be able to mount and unmount a specific partition, this partition contains backups and is usually mounted read only, needs to be temporarily mounted read/write by user1 while doing the backup.user1 is an unprivileged user. I've read that the user option will let any user mount the file-system (and only that user can then subsequently unmount it) and that the users option allows any user to mount or unmount the file-system.I also found this in mount's man pageQuote:The owner option is similar to the user option, with the restriction that the user must be the owner of the special file. This may be useful e.g. for /dev/fd if a login script makes the console user owner of this device. The group option is similar, with the restriction that the user must be member of the group of the special file.So it looks like I'd need a login script for that user to make the user owner of the device file (/dev/voiceserv/backup in this case)
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
# 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 recently installed 32bit maverick and wanted to make it login automatically. I tried enabling auto login from Admin > Login but that didnt work and I was still prompted for my password. Then I went to Users & Groups and changed the password option to Do Not ask for password at login now after I reboot, the user list is shown (only 1 user) and it doesnt ask for password after I click on my username.
However, then it gives a few errors (as i vaguely recall):
1. cannot load .ICE directory in my home directory 2. some error 256 about a gconf-sanity-2 file 3. nautilus cannot load my home directory etc
and then it gets stuck without loading anything (blank wallpaper). i ve tried navigating to my home directory using Alt F2, gksudo nautilus and my home dir contents are encrypted by the ecryptfs (there is a readme.txt file and a shortcut). i have tried to decrypt but it doesnt work... i ve also tried to start/stop gdm, and startx but nothing works. if i stop gdm, then the prompt doesnt recognize my password and keeps on rejecting the commands i enter... I think this has something to do with the home dir not being decrypted due to the dont ask for paswd option... how can i disable the dont ask for pwd without the gui (i can access my / by booting through an external usb).
I press On-button, Debian boots, logs in and automatically connects to the Wireless network AND! to my local pc via LAN. It runs an ssh server, so I can ssh into debian over internet and communicate with the local pc (send a magic packet).Here are my problems:
1) I don't how to log in automatically. This and this doesn't work. 2) I need a network tool that can manage multiple connections and has a reconnect feature. With the default network manager I cannot even connect to more than one network simultaneously although I have two network devices of course.
And I guess I can run all that in console mode, right?
I have program that work like Fedora Firstboot it's run only one time after finish installation. I have two questions to ask.
1. How can I start this application before gdm start (login screen or auto login)
2. How can I start this application in fix display resolution (800x600)
My method now is
(This is a part of script , this script execute from /etc/init.d/myfirstboot , I create symlink to /etc/rc2.d/S1myfirstboot for start it before anything)
gdm-stop # first time I use /etc/init.d/gdm stop DISPLAY=:1 export DISPLAY /usr/bin/Xorg :1 &
I don't understand why first time firstboot start the system will auto loging in but not complete yet and then my script is start and it's work does not fine I think that is another user is already login , but if I re run my firstboot again and again (by setting something that can revoke my firstboot and restart) it's work before auto login and every things is ok!
I typically have several terminal windows each of which is connected via ssh to a remote server. In each window I work using the gnu screen program, to ensure persistence of the interactive processes in case of a disconnection.
Currently, whenever the ssh connection drops (such as when I put my client computer to sleep overnight) I have to manually and tediously restart the ssh session inside each window, and then in each window tediously resume the specific screen session (e.g. "screen -r 3453" in one window, "screen -r 3462" in the other etc.)
Is there an elegant way to automate this? Specifically:
reconnect the ssh session if it drops, as soon as an Internet connection is detected run the specific screen instance for the terminal window as soon as ssh reconnects
we are in a place where we have to give an account (with sudo access...) to a user we don't completely trust (I am reminded of this comic). What we need to set up is some way of logging pretty much everything that this user does, especially what he does as root (via sudo or sudo -s). Now, I know that anything we do can easily be undone by another user with root access, but we feel that if he does disable logging we can use this as a really good excuse to revoke his access. So, does anyone know what logging stuff I'd have to set up to completely monitor one user (it is ok if we are monitoring everyone, but we'd prefer to watch one user if possible)?
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.
To allow specific IPs login to FTP server I'm using
Code: <Limit LOGIN> Deny from all Allow from xx.xxx.xx.xx Allow from xx.xxx.xx.xx (where x there is IP numbers)
and so on, for all IPs I give access to.
But now I have question, is it possible to make something like this but just for specific users? For example there is user 'user1', how to allow login IP 220.127.116.11 to 'user1' account and deny all others ?
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.
Ubuntu install offers the option of automatically logging one in at startup.If you choose this option, you are logged in automatically. However, you are still asked for your password, to unlock your keyring. So all you have done, is saved yourself one click (or one key press of the enter-key).The downside, is that there is no delay of your automatically started programs that maybe wait for you to log in. These can start using improperly initialized resources - like the keyring, I suppose.
In my case, this has resulted in the sound system failing. Restart then resulted in the sound being restored but the Trash folder going missing and so on. Finally, the Quit button on the task bar vanished forever. Perhaps I have identified the cause incorrectly, but that is my assessment and therefore I recommend not to use this login option.I am running 10.4 Gnome 64 bit. The program I started automatically, was Evolution.
I was going through some settings and inadvertently changed the UID for my primary logon. I then realized what I did and changed it back and set the group back to my username.Since then, it only auto-logs in on startup. I cannot get it to prompt for a password again. I've tried normal things like changing "ask for password on login" and then changing it back, but that hasn't helped. I'm sure there's something else that I'm missing, but don't know what it is. Right now, it says "asked on login" but it doesn't.
have a question about auto-login scripts for SSH where RSA keypair authentication is used.Basically, I have a server (say, server1) configured with RSA keypair authentication. This server is connected to another server (server2), that I connect to via server1 and for which I use the same passphrase and public key as I use for server1. I was wondering if it is possible without writing out the passphrase in a file to "forward" the phrase on from server1 to server2 in an auto-login script, saving me having to type it in twice
I just set up my own server and basically my folder is on say /media/disk1/ and my girlfriends is on /media/patato/ is there a way i can set it so that if i log in it goes to my folder and if she does it goes to hers.... I've currently got it set up as /media/ that it goes to but i cant get it to change it for each user (we can also browse each others drive and we dont want that, we want to be tied into /media/ourdirectory and all of its subdirectories) problem is that it is running on a computer that use to be functional (same install because I cant find my disk drive) so it cant use home folders....
Here is what I want to do: have procmail get my mail from all of the different mail servers, and then put them in my inbox folder (I'm able to do all of this), but also have my emails sorted by domain into subfolders.So for example, procmail downloads my email, puts it into the gmail folder which is a subfolder of my inbox folder.I know how to get all of my email into the inbox folder - but not into a specific subfolder.
