Pico Etc/crontab VS Crontab -e

Sep 12, 2006

I have been searching for an answer on this for a couple of days and have yet to find one.

I am running a box with Centos.

If I Pico etc/crontab I get this type of output;


# run-parts
01 * * * * root run-parts /etc/cron.hourly
02 4 * * * root run-parts /etc/cron.daily
22 4 * * 0 root run-parts /etc/cron.weekly
42 4 1 * * root run-parts /etc/cron.monthly

If I crontab -e I get this type of output;

44 21 * * * /scripts/upcp
0 1 * * * /scripts/cpbackup
*/15 * * * * /usr/local/cpanel/whostmgr/bin/dnsqueue > /dev/null 2>&1
2,58 * * * * /usr/local/bandmin/bandmin
0 0 * * * /usr/local/bandmin/ipaddrmap

Why different?

I am taking it crontab using -e is not the same file as etc/crontab?

Using Find Command With Regex To Find All Number-only Filenames

Oct 15, 2007

how can i do a search for all files (probs using regex) of files consisting purely of numbers?

for e.g. find:


(always have 5 numbers).

seems one of my accounts has had some script run which generated a bunch of these in various subfolders, and the php file basically does a callback to www3.rssnews.ws and www3.xmldata.info, which seem to be some sort of spyware servers.

1) #> nano /var/spool/cron/root
Then type in the cron entry and save it
#> service crond restart
It cannot work if have not restart crond

2) #> crontab -e
Then type in the cron entry and save it

3) #> nano /etc/crontab
type in the cron entry and save it

I can use above three method without any problem.

However I cannot use crontab [filepath] method

4) #> crontab /home/admin/domain.com/www/testing/crontab.dat
*crontab.dat is a cron entry.
after type in this line,
I use crontab -l and see cron entry has been added to /var/spool/cron/root
However, the cron job will not run even I restart crond.

Aug 20, 2007

It's been nearly a year i'm running several cron jobs on my CPanel hosting. The format for the command i used is as follows (putting aside the timing info):

php /home/account/public_html/subdir/cron/cron1.php

A few days ago, all cron jobs stopped working, probably because of a certain setting that my host changed. I contacted my host, and he replied that the format i'm using for the commands was not proper, and he gave me the proper command as:

GET [url]

I tried it, but it didnt work....

I googled the problem and got tens of commands... i simply wanna run a PHP file (the file itseld is functional if i browse it) every now and then, so what is the command i should be using?

How Does One Run Crontab Effectively?

Nov 10, 2006

How does one get their cron jobs emailed to them?

How does one run crontab effectively?

I have been trying to start up a new cronjob. I wrote the line command chmoded it to 755 and put it in a folder cron.x

In my crontab I input the following:
30 23 * * * root run-parts /etc/cron.x

the first is minutes
the second hours, right?

At 23:30 on my server time, nothing happened. >_<;; I'd like to have my cronjobs emailed to me so that if there is an error, I can see it.

I've been combing google with little avail (can't find much other than unrelated blog junk on that engine nowadays anyway >_<) I figured WHT would be more useful.

Crontab Permissions

Mar 18, 2008

In trying to setup a cronjob on a new server I notice that cPanel tells me that usr/bin/crontab permissions are wrong and that they need to be changed to 4755.

When I log in to the server with WinSCP and attempt to change the permissions it just doesn't do it ... it looks like it's doing it, no errors, but it just leaves it the same!

Crontab + Php In Freebsd 6.1

Feb 5, 2007

i created a new cron job with "crontab -e" command by using the "root" user.

* * * * * php -f /path/file.php

i tried it for php -q too. while i type this command on the shell the php file works. there is no problem with crontab rule too. the chmod of file.php is 777, user root group wheel..

but it cant work. i couldnt understand why it aint.

i created a shell file and changed the cron like:

* * * * * /path/file.sh

and in file.sh:

php -q /path/file.php
mkdir /path/anydir

so, /path/anydir have been created but file.php not executed. so the problem is not about cron rule.

Crontab In My Server

Jul 9, 2007

I have few servers and when I check my crontab, I found the same line in all servers but at a different time.

43 0 * * * cd /usr/local/cpanel/whostmgr/docroot/cgi/fantastico/scripts/ ; /usr/local/cpanel/3rdparty/bin/php cron.php > /dev/null 2>&1

24 20 * * * cd /usr/local/cpanel/whostmgr/docroot/cgi/fantastico/scripts/ ; /usr/local/cpanel/3rdparty/bin/php cron.php > /dev/null 2>&1

32 19 * * * cd /usr/local/cpanel/whostmgr/docroot/cgi/fantastico/scripts/ ; /usr/local/cpanel/3rdparty/bin/php cron.php > /dev/null 2>&1

3 16 * * * cd /usr/local/cpanel/whostmgr/docroot/cgi/fantastico/scripts/ ; /usr/local/cpanel/3rdparty/bin/php cron.php > /dev/null 2>&1

Anyone can explain what are the purpose for these command, and should I make any changes to these to standardize them all (the time)


Secondly, one of my server doesn't set any automatic CPanel updates, so I set automatic updates for CPanel packages and Security packages. Is it suppose to add "/scripts/upcp" into my crontab? Most of them are also at different time.


I assume this command is to inform me whenever my user make a new domain add-on?
/usr/local/cpanel/whostmgr/docroot/cgi/cpaddons_report.pl --notify


Also can anyone tell me what are the purpose of these?
/usr/local/cpanel/bin/dcpumon >/dev/null 2>&1
/scripts/exim_tidydb > /dev/null 2>&1
/usr/local/cpanel/whostmgr/bin/dnsqueue > /dev/null 2>&1

HTTP Requests With Crontab?

Apr 20, 2005

I set up a cron to run every minute & I'm running a PHP script by way of cron like

wget http://example.com/some_script.php

Now does each request of Cron is a seperate HTTP Request or what? Say my script takes more than 1 minute to execute completely but before its completed, its called again. So, will that effect the PHP script running because of previous HTTP Request or will it create a new HTTP Request & let the previous request finish its operation? Technically, it shouldn't block/affect the previous request, but I'm not sure!!

Not Able To Set Crontab To 4755 In SSH Logged In As Root

Mar 20, 2008

For some odd reason, when I run: chmod 4755 /usr/bin/crontab

in ssh, it still does not change it to 4755. It's like I don't have permission to change it, ans I'm logged in as root.

I've read some threads here on the forum and none really come to an issue where when they run that chmod 4755 /usr/bin/crontab it still doesn't chmod it.

So is there a way to check if it is chmodded to 4755 as I use CSF Exploerer to check if it is chmod'd to 4755, and it just stays at 755.

Apache Auto-restart Script (crontab)

Jan 10, 2007

I have root ssh access to a server and we notice when doing a bash ./mysq-backup script to dump the data from the web site's databases into .sql and .tgz them that httpd goes down sometimes. That, and sometimes it seems that httpd goes down in other situations. All fine, we will figure out why. But ..

It would be nice to run a crontab to check every 15 minutes if httpd is running, if not, to restart it.

Right now I when I notice the site is down I log into the ssh as root and type: service httpd restart. If it is up it will then first stop it, and restart it. I can look at the screen and see it happen, so I feel pretty safe doing this. One of my concerns is that when I am not at the screen and it stays down .. I do not notice this and downtime increases. And we don't want to just crontab service httpd restart, so a bash script to check for the pid and restart if it down .. would be nice.

I thought this would work:
(chmod 755 httpdcheck)

delta:~ root# cat httpdcheck

if [ ! "$(pidof httpd)" ]
echo "Could not find pid of httpd - restarting"
service httpd restart
echo "Found pid of httpd - NO need to restart"
delta:~ root#
And I have this crontab entry:

delta:~ root# crontab -l
*/5 * * * * /root/httpdcheck | mail my@email
delta:~ root#
When testing, I did service httpd stop and waited 5 minutes and I received the email : could not find it, restarting. But when I go to the web site in browser it remains down. I have to login to ssh and do service httpd start manually to really load it.

Manually loading btw .. shows it works as bash script just fine, so I dont't know why it won't work when run from cron?

delta:~ root# ./httpdcheck
Could not find pid of httpd - restarting
Stopping httpd: [FAILED]
Starting httpd: [ OK ]
delta:~ root#

So .. when is it going wrong? Am I forgetting something?

How-To: Find PHP Nobody Spammers!

Apr 9, 2004

Someone posted some code similar to below, I made modifications or two after trying to detect PHP "nobody" users, after dumping a few printenv I found PHP exports PWD when calling an external program such sendmail. Basically the PWD will show the user directory that is coming from, which is enough to detect who is sending SPAM even as nobody! It's not 100% secure in that they could wipe /var/log/formmail but I don't imagine any spam will notice the logger, they presume any cPanel server (or other CP for that matter) is the same.

mv /usr/sbin/sendmail /usr/sbin/sendmail2
pico /usr/bin/sendmail (paste the below code into it)
chmod +x /usr/bin/sendmail
echo > /var/log/formmail
chmod 777 /var/log/formail


# use strict;
use Env;
my $date = `date`;
chomp $date;
open (INFO, ">>/var/log/formmail.log") || die "Failed to open file ::$!";
my $uid = $>;
my @info = getpwuid($uid);
else {

print INFO "$date - $PWD - @info";

my $mailprog = '/usr/sbin/sendmail.real';
foreach (@ARGV) {
$arg="$arg" . " $_";

open (MAIL,"|$mailprog $arg") || die "cannot open $mailprog: $!";
while (<STDIN> ) {
print MAIL;
close (INFO);
close (MAIL);

Where To Find VPS On Litespeed

I tried searching for it on google but couldn't find any server company offering VPS using Litespeed instead of Apache. Yes, I know that Apache could be optimized, but would like to try a VPS or dedicated server with Litespeed, just for testing and learning to use and troubleshoot Litespeed. Does anybody here know of a supplier? I would need less than 10 gigs, 250+ Ram as well as cPanel.

Where Can I Find 10+ Tb Bandwidth

Sep 4, 2008

Here's my situation:

I run a site that does a lot of transfers AND uses a lot of CPU resources. I think I would like to get two different hosting plans to deal with these different patterns of usage, but where can I find a good host offering lots of bandwidth that is content to have it actually used? I've been with DreamHost for a while but they don't allow "data archiving" or whatever (and I have arguments against their claims but it's neither here nor there). So, really, where the heck can a guy find a good host offering plenty of space and bandwidth? Keep in mind I need pretty much no CPU power with such a plan; the web server can be stone cold stupid for all I care, as I can just get a VPS to run the CPU-intensive part of my site!
