Is it possible to send a message to a specific user of group with "wall" command? Seems that this command will broadcast the message.

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 2.6.33.6-147.fc13.x86_64) without any other significant issues.
I'm working on a kiosk-type system. What it needs to do is boot, auto login as a specific user, display only the Gnome desktop (no icons, etc), and auto start an application.
Is this possible (I'm sure it is)? If so, can this be scripted, i.e. without having to use graphical tools like Sabayon.
I am running few tasks in my linux console and want to be notified by some kind of alarm, so I don't keep checking the progress of the task.
Is there a way to customize the alarm by specifying additional filters like "ERROR" message, etc? I think it will be a useful thing to have.
I'd like to limit login attempts for specific user. I've found information in manpages: [URL]but I'm not sure if this '@' is purposly there, so would be that correct?
Code:
aparaho - maxlogins 4
or
Code:
@aparaho - maxlogins 4
Maybe '@' is a group syntax? I'm confused.
What happens after 4 failed loggins? Is it enough to restart system to get another login attempts?
Are there any other values that it is reasonable to limit for safety reasons?
i'm in search of Script that sends a mail to the user if the mount point goes beyond 80% of its full space.
send mail is configured in the system so that it can communicate with mail server.
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?

View 2 Replies View RelatedAt first I tried the using the CDROM to install the server but around 8% through it could not talk to the CDROM anymore. I did attempt this a few times including re-seat the CDROM and it stopped at the same point every time. I then used the Mini install and that worked. However, after I rebooted I received the this error.
Gave up waiting for root Common problems:
Boot args (cat /proc/cmdline)
Check rootdelay
Check root
ALERT! /dev/disk/by-uuid/bfaafj88-83ce-4dd2-8c6f-26o9a869eaea does not exists Dropping into shell:

I then reboot from this point by issuing the reboot command and can then go into the rescue login with networking. I did select reconfigure GRUB and rebooted but same error as above.

Ever since installing aMSN 0.98.2 I have not been getting the normal audio notification of incoming messages although that feature is enabled in the program. Actually, I do get an audio alert for the very first incoming message but after that, nothing. Other audio alerts, such as when someone signs in or out, do work fine. I am using Ubuntu 9.04. The Windows version of that release works fine and that's what I've been using in recent weeks but I hate going to Windows for my IM.
View 1 Replies View RelatedI have a real system user say 'test', created in a number of system groups, up to 3 additional groups (including ftp of course). Its set to the usual standard directory /home/test. But what if I wanted to use /home/test as their home directory but login to what would be unknown to them to be ProFTP to make them go in say [URL] or something random like that, how is this done? Just been through things like this:

ServerName "ftp.mydomain.com"
ServerAdmin "me@localhost"

But nothing seems to work.
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,
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.
View 5 Replies View Relatedmy 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)

View 1 Replies View RelatedI have a need to run a specific app as a specific user when the machine boots into init 3. I can not run this as root so I need to specify a user. Can someone tell me how to accomplish this?I usually have to log in and start this application by typing check -D which starts this app and daemonizes it. I want to be able to run that at boot with my normal user not root.I hope I explained this correctly.I have added it to rc.local but it runs as root.
View 3 Replies View RelatedI am looking for a way to deny telnet and ssh to one specific user. So far I've only tested with telnet and my attempts have been limited to various hosts.deny entries:
in.telnetd : user@server
in.telnetd : user@server.domain.com
in.telnetd : user@IP_address
in.telnetd : user@.domain.com
None of these work. The only thing I've found that does work is:in.telnetd : IP_addressBut this is only a semi-viable solution because we will soon have multiple logins for the one username from different servers and sub-nets. Ideally, I'd like to be able to deny telnet and ssh access to this username regardless of where the login originates. I suppose it would be possible to specify each server IP, but that'll be a bear to maintain
i have created a file (by root user) called test.txt. Then i created a user bob. Now i want only bob to read/write/execute this file and no other user shall have any permission on it.
View 3 Replies View RelatedSo right now VNC is starting a session using :1. When I connect to that session, the terminal is logged in as root. I'd like for the terminal to be logged in as a different user as some of my end users are going to be using this and don't require such privileges. I found that I can "su" to a different user and start a new VNC daemon on :2 and when I connect to that session, the terminal is logged in as that user. What I want to do is get that to run at boot-up.
View 4 Replies View RelatedI was logged in, but had not used the computer for about 48 hours. When I 'woke' the system, I could see that Thunderbird and Firefox were active, just as I had left them. I moved the mouse, the screen went black and the mouse pointer was visible (and could move). The system stayed like this for about 2 minutes, then wend down completely. I cut power, booted and got the login screen. Each time I put in my password, it looks as if it is loading but then just goes right back to the login screen. I have no problem logging in as root.

View 3 Replies View RelatedI 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.
i wonder, why nobody has written about it ...
How can i grant permission for files to specific user or specific group ??
Updated:
We have 3 groups: "g12" ("u1" and "u2), "g34" and "g56".
"g12" should only read the file.
"g34" should write and read it.
"g56" should have all permissions (rwx).
And others should not access the file at all.
It should not have any /home/. It only can access a folder and that folder is home default for this account.
Details about my usage: We have a simple folder which contains demo code and we want to create a user to read this folder only
I run the openssh daemon on port 22 and have the proftp running on port 21.

View 7 Replies View RelatedI did some digging on the sudo command and I do know the config file is /etc/sudoers Read the manual for sudoers and found out that I must use visudo to edit the file I read some of the examples at the bottom of the file and tried entering my own account in following the example. one of the commands I was trying to allow my account to perform without root login is the mount command So I tried adding this in (kreid8 /bin/mount ALL) I then saved & exited the file and logged out of root and tried sudo mount -t vfat /dev/sdc1 /media. I got an error saying I had to be root in order to do that But when I use the visudo -l option it shows that I have that privellege. Did I edit the file incorrectly?
