Well, both sntp and cron are operational, so you should not have a problem. It may be perhaps because of how cron works. Do all the other cron jobs work?

[snakessj]

Yes, I think, viewing log file:

Jan 31 01:00:01 | USER root pid 648 cmd /usr/local/bin/memopt.sh& }/dev/null 2}&1

In which case the other one will work (eventually) if you let it be.

I have a doubt, does crontab realize in real time when its list of jobs changes?
However crontab -l, after jobs file modification (adding my wget command), lists all jobs including wget...

[thechief]

I think you will need to read up on the crontab manuals - particularly the busybox cron applets. But it is best to have the cron jobs in place before crond is executed (which means an "RT_init_x" or "RT_cmd_x" setting).

[snakessj]

Ok, tnx!

[thechief]

I guess the eye-rolling means that you are unwilling to read the cron manuals for yourself, but you would prefer someone else to read them for you and tell you what is in them? If so, then you've come to the wrong place.

Mmm, my main problem is that I am italian and I don't understand (and write) well english... however I read the manual (http://sharedhosting.net/support/crontab/man.html) and I found (I think) the problem:

Note: All crontab jobs should be submitted using crontab; you should not add jobs by just editing crontab file because cron will not be aware of changes made this way.

In reference to "-e" option! At this time I can't try because I'm not in my home, (d'oh ) but as soon as possible I try and say you the result!

[snakessj]

I finally managed to make crontab see the new job! I made it setting the editor this way as default:

Code: Select all

export VISUAL='edit'

and using CRONTAB -e command

I then, after various tries, due to the previous syntax errors, added the wget command this way:

Code: Select all

* * * * * wget -q http://www.mysite.com/script.php

The problem now is that it looks like it's being executed but it actually isn't!
Log says:

Code: Select all

Feb  2 00:49:01 | USER root pid 658 cmd wget -q http://www.mysite.com/script.php
Feb  2 00:51:01 | USER root pid 667 cmd wget -q http://www.mysite.com/script.php
Feb  2 00:52:01 | USER root pid 672 cmd wget -q http://www.mysite.com/script.php

but the script is not being executed ! If directly use "wget -q http://www.mysite.com/script.php" instead, it's perfectly performed. I've been looking everywhere in the Internet and I keep on finding always the same examples, but they won't work...where am I doing wrong? =(

PS: my girlfriend's helping me with my English, that's why my language has suddently improved XD

Permissions on the script perhaps ?

[thechief]

I think there may be an issue with busybox crond and external commands. I'll investigate further over the next few days ...

Edit: investigated - no issues found - all is well.

[biro]

Does script.php actually get downloaded ?
Think you will need to specify the download dir

Code: Select all

wget -q -P/var/ http://www.mysite.com/script.php

even then may need to set permisssions and the execute the script.

wget -q -P/var/ http://www.mysite.com/script.php

Yes, indeed.

I've tried and now i have this error:
