I have the following cron entry but it doesn't seem to be running:
Code:
The script does exist. And so does the directory /home/usr/log and writable. /var/log/syslog only has a bunch of these:
Code:
I don't see any file gets written to the log directory. That suggests to me that cron didn't run the job, as confirmed by /var/log/syslog.
How to find a file which is being written recently in directory of 1000 files?

I'd like to make a directory entry (like a symbolic link) that point to the fixed record area into a .dbf file. Is it possible in linux? The request is motivated by access a .dbf file from a Firebird SQL Database using CREATE TABLE EXTERNAL FILE '/tmp/mydbf.dbf' ( ... ); but this command only works on fixed records.
View 1 Replies View RelatedI have noticed that in the /etc directory there are some subdirectories of /etc/cron.daily and /etc/cron.hourly. Also I have determined that there is a service included as part of the Fedora OS 'crond' which I have started with the use of 'service crond start'. My question is this. If I drop an executable file into the '/etc/cron.daily' directory will it just run? If not what configuration files should I go about editing to run my executable daily? There seems to be a pretty large network of cron related files. I'm trying to make sense out of all of it.

It's meant to move old files from my Downloads folder into an archive file (later tar them). The directory exists, I've used $PWD and nautilus and ls to make sure it's there, yet for every file it gives

I have a requirement that a job run at a particular time every other Friday. I was wondering if I can configure cron to do this - perhaps using the /step feature? For example, can I do the following?
0 21 * * 5/2 /my/command
If this works, how does it decide when to begin skipping? In other words, where is the first Friday? Is it the first Friday of the Year? of the Month? I would just try it, but it would be an awful long time to wait to see whether or not it is working.

I run a virtual server with a standard minimal openSUSE 11.4 installation (Strato image) and all recent updates installed.
Code:
$ uname -a
Linux servername 2.6.18-028stab089.1 #1 SMP Thu Apr 14 13:46:04 MSD 2011 i686 athlon i386 GNU/Linux
A few days into running the server I found that although /usr/sbin/cron was running it didn't execute the cron scripts. Instead, I find this:
Code:
$ tail -n 3 /var/log/messages

Jun 28 18:00:01 servername /usr/sbin/cron[28590]: (root) FAILED to open PAM security session (Cannot make/remove an entry for the specified session) repeated every 20 minutes.
I have this:
Code:
$ cat /etc/pam.d/crond
# The PAM configuration file for the cron daemon
# No PAM authentication called, auth modules not needed
auth sufficient pam_rootok.so
account sufficient pam_listfile.so item=user sense=allow file=/etc/cron.allow onerr=succeed quiet
auth include common-auth
account include common-account
password include common-password
As per the standard installation and /etc/cron.allow doesn't exist (I tested if it made a difference if it existed with the single line root in it, but there was no effect). I need cron to execute because I want zypper to auto-update my server. On my home openSUSE 11.4 installation the problem doesn't exist. Is it perhaps related to the settings in the yast security center?
I'm trying to edit mobi files. To do so, I looked for a mobi2html program, which I found here:URL...I followed all the instructions mentioned in the READ_ME file that comes with the zipped source. I strongly believe, as no error messages appeared during the installation, everything went according to plan.My question is simple: having completed all the installation procedures, what should I do next? My general procedure is to look up for the new program name in the "applications" tab, but I know that won't always do the trick.

Password: su: /bin/bash:/sbin: No such file or directory i cannot delete that entry from /etc/passwd as i cannot login as root.
I have a small ubuntu server setup and I would like to create a directory that can be written to by a select number of users. I have a backup directory setup and I want to enable my account as well as three others to be able to read/write to that directory. So far I haven't had any luck.
The owner of the backups folder, a directory on a separate disk mounted under /srv/storage, was owned by root and under the root group. I added the group backups and then changed the backups directory group to backups. I then used chown to change the backups directory to 775 to enable group members to write to it. I then tried to touch a file in the backups folder but no such luck. I did notice that when I run groups, my user account isn't shown as belonging to backups but is shown under the /etc/group file. I even made sure the GID of backups is in fact below 1000.
Anyone have an idea on how to create a shared directory that everyone can create, modify and delete any file? I believe my problem is related to the fact that root is the owner of the backups directory.
I just tried the simplest 'Hello world' example as below.

My root Vixie cron crontab is set to perform a system snapshot via fsarchiver: 0 0 * * * fsarchiver savefs -o -A /backups/p30_root.fsa /dev/sda2 /dev/sda3 The command itself works fine, generating about a 7G snapshot of my Suse server. I then wish to rsync this to a NAS I have located in another building: 0 3 * * * rsync -av -e ssh --delete /backups/ root{at address}:/DataVolume/os_backups/
(yes, I'm rsyncing as root. I absolutely loathe it, but I got thrown into an quasi-SA position with a ridiculous to-do list and no time to do it. I'm having to make things just work and then go back and try to improve them/learn how. I couldn't make it work in a non-root way quick enough, so for now I'm having to cron rsync jobs as root because of all the differing file permissions on this samba/MySql server. I set the NAS to only accepts ssh from the server IP, and we're behind a campus firewall... It's serious trial by fire.) The crontab also has rsync commands for the samba areas, our specialized chemistry software and affiliated MySQL databases............
htop is my preferred system monitor, but I have a problem with it in Unity: When I open htop from the Applications lens there's no entry in the launcher added for it. This means I can't add it permanently to the launcher. It may have to do with it being a terminal based program, but I was wondering if there is a way to get it permanently added to the launcher?
View 3 Replies View RelatedI need to create and access a very large number of directories (and by large I mean millions). Each directory's name consists only of numbers, which are incremented every time a new directory is created (so there will be directory 1, 2, and so on).Of course I could just dump all these directories under the same parent directory, but I reckon I would run into filesystem limits. Moreover, I presume that entry lookup is not a O(1) operation, which means that lookup does not scale well.
One solution is to use some sort of prefix tree for storing the data. In this scheme, the data for directory "1234" would actually be stored in "/1/2/3/4".This solution has the advantage that each subtree never has more than 10 entries, but the disadvantage of requiring as many individual lookups as the length of the path.There are also intermediate solutions: using a maximum of 100 entries per directory, "1234" would become "/12/34", per example.In order to choose the best scheme, I must know more about the scalability of directory lookup under Linux. What's the maximum reasonable number of entries for a directory before lookup becomes too slow? Does someone know exactly what are the limitations of the algorithm used for directory lookup?
why my second cron job isn't running? The first one runs fine but the second one does not run at all. If I manually run the script using ./check.sh then it does what it is supposed to but will not run from cron. It should run every weekday at 9:45am, it looks good to me but clearly I am doing something wrong.
Code:
# m h dom mon dow command
#This will backup my hosted websites.
0 2 * * * /home/bob/scripts/websitebakscript.sh
#This will run check and upload it's contents to the net.

Cron refuses to work for a newbie.I am trying to setup a cron job to backup a folder in my home directory ('/home/scratch') to a folder ('home/internet_backup') that is mounted (using nfs) to a network folder.the folder ('home/internet_backup') is mounted correctly to the network folder upon system startup, so this part works.

I seem to be having a problem with cron. I have a python program that checks a specific directory for pending email scripts written in python.
Code:
#!/usr/bin/python
import os
emaildir = os.environ['HOME']+"/email/"
filelist = os.listdir(emaildir)
for pyfile in filelist:
if pyfile.find(".py") > -1:
execfile(emaildir+pyfile)
This code has been tested and works fine. The problem is that I need cron to run this code every 5 minutes but i can't tell if it is running: Here is my cron code:

I have a cron job that executes fine in opensuse 11.4. It is located in
/etc/cron.d/publish.cron:
jpablo /srv/django-apps/smcommand/scripts/publish.sh
It is correct, I want it to execute every minute. Now, I copied the same script to ubuntu maverick, and it doesn't run. Perhaps there's some ubuntu peculiarity that I'm not aware of?

The script is executable, owned by root, and root is the group, with 755 permissions.

I use the show-leaves yum plugin, and sometimes I use that info to remove some unnecessary packages. But that list can be long, so I write them on a text file.
1) Instead of removing packages one by one is there a way to remove all packages written in that text file?
2) Why isn't the output of the show-leaves plugin compatible with the output of "package-cleanup --leaves"?
In my nagios server, an htaccess file have been created for it so any time you want to open it, a window opens for you to enter user name and passwords. Now, what I want to do now is to integrate the nagios into a portal that is written in php so that when customers login to the portal, they can access the nagios with out it popping out the user and password windows. What is going to happen is, the password of nagios will be store in an orient database so the users when they try to access nagios true the portal, they will be login automatically.
