Fedora :: Unable To Use Crontab As User On System?
Mar 31, 2011
I am unable to use crontab as a user on my system.
Code:
The error is: You (user) are not allowed to access to (crontab) because of pam configuration. I did just recently do an update but I am not sure why this is acting up. I also tried it as root and it also failed with a similar message. I had several crons that ran daily and they are not currently working also. I have selinux Disabled and it has been that way for some time.
I am using Linux 64 bit Redhat Linux. I am trying to setup simple crontab as follow...1. Edited crontab file using crontab -e2. Listed the file once to verify it using crontab -l. This will display as.. 18 5 * * 2-3 ksh $HOME/testScript.sh > $HOME/testscript.out3. Logged in a root and restarted cron deamon using "/etc/init.d/crond restart"As per my understanding now my testScript should start running at 5:18 am Thuesday
lately i notice that when i add a new user withthe useradd and passwd command, and then try to login using this new account, am being prompted with a message,saying ' you cannot access /home/newuser. that the account doesnot have permission on his home directory. i have even tried go give the user(john) ownership over his home directory with the #chown -R john:john /home/john
I have dual boot (wubi) Windows XP. It was working smooth until I upgrade ubuntu 9.10. At the boot screen I choose Ubuntu, then it ask me wich version, then it freeze. I tried the recovery version, but then it ask me for a user ID login and password. At this point I'm able to enter the user , but it don't type anything on the password and keep asking me to enter the user id and password again, and again.
I need to edit the system time as a not-root user. I am carrying out the following actions in my program.
1. Read the User Id of the process. User_ID= getuid() 2. Printing Capabilities(Permitted, Efffective, Inheritable)of the process 3. Setting UID = 0, using setuid(0) 4. Calling the prctl(), function to keep capabilities 5.Switching the UID from root to User_ID of the process 6. What we have now is a process with root capabilities as a non root user 7. On printing Permitted, Effective, Inheritable capabilities, I get the following --> Permitted = 0xfffffeff = Effective Inheritable = 0x0; with UID = 1001; 8. I then try and set the system time with --> system("date -s 10:00"); 9. I get an error: date: cannot set date: Operation not permitted 10. I am unable to understand as to why I cannot set the time even thought the capability bit CAP_SYS_TIME in the Permitted and Effective sets are SET.
i know the subject is hard to understand but i did my best with it. the problem: i have 2 HDs on my Ubuntu OS, the first is 1TB and the other is 500GB, i want to do a backup with rsync from my 1TB HDs (in with the Ubuntu is on it) to the 500GB.
on the 500GB i have a partition called Backup. what i did: i have created a user crontab that dose two things: 1. mount the Backup partition from the 500GB to a folder called /~/Backup on my home directory which is on the 1TB HD.
2. i wrote the proper rsync command for the backup to go.
Is there a way to view all the crontab files, owned by root, users, and other system accounts, that exist on a system simultaneously rather than having to go the individual accounts? The distribution in question here is the Debian 4.0 release.
is it possible disabling a crontab job without deleting the crontab description entry (by crontab -e)?I could also accept to change the entry itself. Now it's:0 0 * * 0-6 /home/me/cron/script.csh
when a script in /etc/cron.d directory will be executed?. I know that scripts in cron.daily will be executed daily [ set in /etc/crontab file]? Cant able to find this directory listed in /etc/crontab file?
After upgrading FEdora 13, user ravi was added. Then after few days neel was added. Both of the users were already existing. So when attempting login to neel, we found that every file is owned by ravi. So we did$chown -R neel:neel But after that problem started and when we rebooted the machin, there were no list of users on login screen. (then I connected to that comp remotely, it worked, but somehow I was not able to switch to root) It says incorrect password (though I new it very well). So I went to maintenance mode and changed the root password, and rebooted. Still problem persists.Now I am not able to login as root (from anywhere, login screen , terminal, remote)No list of usernames on login screen ( but i can choose, other and type login-password)
I have just upgraded my laptop from F8 to F10, and I am unable to login to the system as root user.At login, it provides 2 options, one is the user I created and another called 'other'.On selecting 'other' and providing uid/passwd as 'root/<rootpassword>, it says "Unable to Authenticate User"!!However, when I tried to access my windows partition, it happily accepted the root password
I am able to ftp the root of my EC2 instance of fc12 with a private key. I do not know what commands were given to fc12 to get it to act this way but that is okay, it works for me.
I have created accounts for my users and set a password for each of them. The problem is that I am unable to ftp fc12 with the user name and password. The error message I get says there is no supported authentication method available.
I presume I must somehow change server security or something to allow access to users with passwords but I do not know how to do this.
I created an account using the following command:#useradd -g developers john and successfully changed the user password with:#passwd johnThe user is unable to login using the New Password using SSH. As a root I can login (#su - john) with no problem.
If I'm getting good at anything with Fedora, it would be making mistakes. I have Fedora 12 installed and it was running fine until I attempted to set the path in bashrc and cshrc for jdk. Now I am unable to login using the only user account I created at install. When I enter my password the login screens goes blank then my mouse pointer appears with the circling dashed loading symbol for a few secs and then brings me back to the login screen asking for my password again.
I am able to ftp the root of my EC2 instance of fc12 with a private key. However, I am unable to ftp a user account on a EC2 instance of fc12.I do not know what commands were given to fc12 to create an AMI that uses a private key instead of a password.As root administrator I like it. However, I am trying to set up users in such a way that Windows users using "My Network Places" can access my EC2 instance of fc12. I have created accounts for my users and set a password for each of them (useradd). The problem is that I am unable to ftp the fc12 server with the user name and password. The error message the client gets when it tries to do so says there is no supported authentication method available. I presume I must somehow change server security or something to allow access to users with passwords but I do not know how to do this.
I'm trying to get the "root" user to be included in the list of users that get displayed on the login page.
I found this:[URL]...which seems to indicate that if I add an "Include" line, with the "root" user, that would work. I found the /etc/gdm/custom.conf file, which was empty except for the section header lines, so I added an "Include=root" line, but even after rebooting I just get the regular users, and have to login by typing the "root" username, etc.
So, I was wondering, is there a way to get this to work? P.S. I understand about not wanting to allow root logins, but I need to do this in my situation.
I was trying to install winbind on a RHEL5 machine and I had to reboot the RHEL machine. When it came back up, I'm not able to log in as root or any other user.When I use root and give a random password, it says invalid username or password but when I use the correct password, I get an Authentication failed pop up box (under GUI). SSh window says invalid password for random passwords and the SSH window disappears when I type in the right password.Can you please let me know if I can somehow get back in by stopping any of the services
I have a question about using crontab with /etc/crontab...
I had a cron job that I needed to run as root. At the time I thought that sticking it in /etc/crontab would be a good idea. However, I used the crontab command to edit /etc/crontab, which I guess is not standard procedure? Specifically, I configured /etc/crontab as my local user's crontab (i.e. sudo crontab /etc/crontab) then added my cron job as I would a local user crontab (i.e. sudo crontab -e).
Originally, my cron job looked like this:
30 * * * * root /my/batch/script &> /dev/null
After adding the new cron job I started seeing errors. Something to the effect of "can't find command root" or something similar. So I removed the 'root' user definition from the cron job and the job started running fine. However, because this is /etc/crontab, there are other system related cron jobs that have been defined to run under the root account (e.g. "17 * * * * root cd / && run-parts --report /etc/cron.hourly" runs as root, etc.). So these pre-existing system cron jobs, which up until now have been running smoothly, are now generating "can't find command root" errors. But I think that the system cron jobs _are_ successfully being run someplace because logrotate seems to be working.
So what I _think_ is happening is that /etc/crontab is being run twice: once as the system crontab, and once as my sudoed local user's crontab. When I run crontab -l I see nothing, but when I run sudo crontab -l I can see the contents of /etc/crontab. I am reluctant to delete my sudoed local user's crontab, because then in the process I would be deleting the system crontab, and I do not know how I should restore the system crontab's contents. (I am still not sure as to the most appropriate way to edit the system crontab).
How can I get out of this mess? I want /etc/crontab to go back to the way it was before--running _once_ as the system crontab. As for my new cron job, I'm willing to reconfigure it anywhere so long as I am still able to run it as root. Any ideas? (I am using Ubuntu 8.04 Server LTE)
I have installed an application manager(monitoring application) on my linux server. Now, i need to have backup schedule for my application. The application itself has executive file to backup database.But when i put this file in my crontab to schedule the backup program it wont run!50 09 * * * root /opt/ME/AppManager9/bin/BackupMysqlDB.sh
Having just installed fc13 and downloaded the KDE package I attempted to log out as user and back in as root, but I keep getting a message about the wrong password. This is odd as the same password works in terminal if I try to become a SuperUser. I have tried turning off SELinux to no avail. I cannot log in from cold as root,only as user.
I have added a new user by following command : root# useradd -u 100 -g 120 -d /product -s /bin/bash sandesh I am not able to access it in /export/home directory..?
What is the difference between creating a "regular" user and creating a "system" user on Linux?
For example:
Code:
adduser john
Code:
adduser --system john
Similarly it seems there are normal groups and system groups. Doing an internet search and reading man pages does not give much information on the whole concept of system and regular user/group.
I get the following message in my F11 system when I try to yum update system.
ERROR with rpm_check_debug vs depsolve: kernel-uname-r = 2.6.27.37-170.2.104.fc10.i686 is needed by (installed) kmod-nvidia-2.6.27.37-170.2.104.fc10.i686-180.60-1.fc10.6.i686

The only user that can make the sound card work on a F10 x86_64 system is root. For non root users, I am not seeing any error messages when a app tries to use/access the sound card, just nothing plays. As I said, for root everything works as expected. I am sure this is a permission/setup issue, but I have no idea where to start.
I am setting my cron to work. I am in the roo account/ So first I type as vi crontab -e. Then it ask me type "visual" for normal mode and do that then I type the following as below 1 * * * * root usr/local/testClient/runClient.sh>/usr/local/testClient/cron1.log and press esc type wq. Then I restart the cron service /etc/init.d/crond stop and /etc/init.d/crond start. Lastly when I type crontab -l it tells me no crontab for root.
