I've just set up my first cron-jon to run a stock script every night.
Running it manually works fine.
It's stored in /admin/stock_update.php
The command i'm running is /usr/bin/php -q /admin/stock_update.php
But I'm getting emails saying no input file is specified?
Any ideas?
Cheers
Network services almost never expose actual paths on the server's hard disk drive and even if they could it isn't a behaviour you can rely on. So the fact that your file is located at /admin/stock_update.php in the FTP server doesn't say much about actual location on disk, which is what local command-line utilities expect.
In PHP, you can find path on disk of current file with the __FILE__ magic constant. You can create a test script:
<?php
var_dump(__FILE__);
... upload it to the same FTP location and execute through the web server. If that's not an option because files in your FTP account in not visible from the web you can run the file from cron and check the email.
Do you have CloudLinux kernel installed on that server and CageFS filestyem? If yes try running this:
cagefsctl -w cpaneluser; cagefsctl -m cpaneluser
Then try running the cron again

I have an application monitoring files sent to a FTP server (proftpd 1.3.5a). I am using pywatchdog to monitor file creation on FTP server root (app running locally), but under some very specific circumstance it does not issue a notification: when I create a new dir through ftp and, after that, create a file under this directory. The file creation/modification events are not caught!
In order to reproduce it in a simple way I've used pyinotify (0.9.6) itself and it looks like the problem comes from there. So, a simple way to reproduce the problem:
Install proftpd and pyinotify (python3) on the server with default settings
In the server, run the following command to monitor ftp root (recursive and autoadd turned on - considering user "user"):
python3 -m pyinotify -v -r -a /home/user
In the client, create a sample.txt, connect in the ftp server and issue the following commands, in this order:
mkdir dir_a
cd dir_a
put sample.txt
There will be no events related to sample.txt - neither create nor modify!
I've tried to remove the ftp factor from the issue by manually creating and moving directories inside the observed target and creating files inside these directories, but the issue does not happen - it all works smoothly.
Any help will be appreciated!
My zip function isn't working when being called from a php script, but works straight from the SSH prompt.
code in the PHP file that returns nothing var_dump( exec('zip -r domains.zip "domains"') );
code in the php file which works as expected var_dump( exec('/usr/bin/zip -r domains.zip "domains"') );
I've added the path to /etc/profile, I've added it to my ~/.bashrc but can't get the web user to be able to use it.
I'm new to this and it's a VPS so I'm not sure where to go from here.
Ensure that permissions are adequate on the files being accessed - you want to ensure that the user accessing them is able to execute them.
I don't know if this was an effect of the shellshock attack which my server was victim to (or another attack that worked) but it basically enabled the hacker to overwrite my SSH config file when the server rebooted.
This new file used wget to load in a file from a website, then another library of hack functions which I guessed he then used to run hacks/DOS from my server. I caught it pretty fast and ideally want to upgrade but because I have cancer and just had a big operation it is too much effort at the moment.
Therefore I did a lot of house keeping, changing passwords, removing shell access, reverting back to DASH, replacing the default shell for root and any other users to another folder with symbolic links, restoring the config file for SSH, removing CGI functionality from config files e.g
ScriptAlias /cgi-bin/ /home/searchmysite/cgi-bin/
#
allow from all
#
Removed AW stats and Webalizer for all virtual min sites.
I already had DenyHosts and Fail2Ban installed.
I also blocked in/outbound traffic to the IPs of the sites he was getting the files from.
However it seems since this change I have lost the visual cron manager from webmin.
When I go to the menu item "Scheduled Cron Jobs", it says, "The command crontab for managing user Cron configurations was not found. Maybe Cron is not installed on this system?"
However I can see in the file system it exists.
When I run crontab -l or crontab -e I get "Permission Denied"
whoami shows "root"
I did think at the time of the hack this was all related and he had used SSH and a Cron job to get his hack running.
What I want to know is how I can get the CronTab manager back.
All the cron jobs are still running such as importing feeds into my websites, running scheduled emails and so on, what I don't know is how to resolve this without a full rebuild.
If I had the time and energy I would do that but I am totally drained and before this hack everything was just running smoothly and my websites which bring me in money were working fine.
They currently are still working fine and I regularly check my logs for IPs that look odd, have strong htacess rules for xss/sql/path travesal/file hacks and ban whole countries from Cloudflare which the site sits behind. So I don't "think" the machine is compromised at the moment even if it is old - could be wrong though!
details of box
Operating system Debian Linux 5.0 Virtualmin version 3.98.gpl GPL WebMin Version: 1.610 Kernel and CPU Linux 2.6.32.9-rscloud on x86_64
So if anyone can help me get my crontab manager back that would be great.
Thanks
1) check if chattr exists, if not, download a new one.
2) type whereis crontab, then chattr -isa /path/to/crontab.(usually /usr/bin/cron) then chmod crontab back to it original settings.
3) navigate to /var/spool/ and
chattr -isa cron
cd cron
chattr -isa crontabs
4) remove cron entry in /etc/cron.weekly
Look in /etc/cron.weekly for any new
I want to somehow automatically upload files every 5 minutes. I want to upload/transfer the files from my linux vps to my web host.
What I'm trying to do is upload some logs files generated on my vps to my web host so administrators can access it with an .htaccess file.
use wput along with cron to ftp files to your host
wput [options] [file]... ftp://[username[:password]#]hostname[:port][/[path/][file]]
You will probably have to install the tool as its not included by default (at least it hasnt been on most of my installs)
You'll want to set up a cron job for this. The Wikipedia page for this has a nice overview of how the crontab file is laid out. However, you should check your distribution's documentation for better information (they could be using a different version or a completely different cron daemon).
The line you'd add to the crontab would look something like this:
*/5 * * * * <user to run command as> <your command>

Hopefully your web host provides SCP or FTP servers to allow you to copy files over. How do you transfer files when you're uploading your web site files?
If it's ftp, use the ftp command:
ftp -u user:password#host/destination_folder/ sourcefile.txt
If it's scp, use the scp command:
scp foobar.txt username#host:/some/remote/directory
I am currently writing an admin page for my webserver, to make it easier on myself to create new apache domains from my browser. Everything is pretty much working as I want it to, except for one thing.
To elaborate: I have a cron job on my server running a bash script as root that checks a file containing a list of domain names that I want to be created. If the file contains a domain name, it automatically creates a new virtual host for this domain, edits my hosts file, and restarts the server. This all works perfectly, however what I would like for the script to do, is that it activates the domain that it automatically creates before it restarts the server. I tried doing this using apache 2's a2ensite command, however the script returns an error saying the command is not found.
Is there a way to call this command from a bash script, or is there an alternative to this command that I can call?
Any help would be greatly appreciated.
$ which a2ensite
/usr/sbin/a2ensite
Usually, cron has a quite restrictive $PATH, not including /usr/sbin or /sbin, which are system binaries (for use by root). It's always a good idea to use fully qualified path names. So either call /usr/bin/a2ensite in your script, or define a variable:
A2ENSITE=/usr/sbin/a2ensite
...
${A2ENSITE} new-domain.com
