Hi,

During the last 24 hours, httpd on my plesk server has gone down twice. It came back, when I reboot the server through Plesk admin login. I do not have any good knowledge. Can someone help me by analysing the following extracts of error_log, from my server:-

[Thu Apr 11 17:55:59 2002] [error] [client 216.35.116.122] File does not exist: /usr/local/psa/home/vhosts/default/htdocs/robots.txt

Please suggest me what is going wrong on the server, and how can I rectify that??

Thanks

You're not the only one there.
I noticed this line right at the top of your page. I have that too. Damned script kiddies!! Grr!!

From what I can gather from my server it seems to try and reboot itself when the script kiddies give it a lot of hassle.

James

I think, the real problem lies in the following lines (damn, I am illiterate to understand these lines):-

Anyone for help!!!

From that I don't think it's got anything to do with s'kiddies as robots.txt might simply be a search engine crawling your ip / domain.

Well you have a point...
have you got a firewall up ukagg? cause i think you may find that it blocks access to port 443.

James

No, I have not installed any firewall. I posted the same query at Plesk Forum, and someone suggested me to read:-

http://forum.plesk.com/showthread.php?s=&threadid=2409

Please comment, what you you think after reading.

Thanks
Umesh

Here's the deal: when you change something in PSA (i.e. add a domain) and exit, it stops and restarts the Apache server. If your server is somewhat busy with other things when you do this, the restart script doesn't work - it shuts down Apache, then tries to restart it without waiting long enough. The original Apache process hasn't quite shut down, so the new one gets the "could not bind to port 443" message.

Looking at your log, I'd say this is quite likely to be your problem.

The solution is in the Plesk Forum thread you found. I made the changes suggested there and also made a cron job that checks Apache and restarts it automatically - but after fixing the script as per that thread, Apache never stops in the first place.

All you need to do is edit the /usr/local/psa/rc.d/httpd file. Find this section:
...and add the functions from the PSA thread immediately after the above:

Finally, find this line:...and replace with:

That's it. Once you've saved that file it will kick in at the next restart and Apache shouldn't die.

You are right , guys !

But it seems this problem already has been fixed with 2.5 release.

I recommend the upgrade to 2.5.

GREAT!

How did you upgraded to 2.5.... I mean do you need to pay for this upgrade? any problem faced during upgrade?

Thanks
Umesh

2.5 uses the same keys as 2.0

I did a lot upgrades (Linux, FreeBSD) - only one problem had been happened under FreeBSD (FrontPage configs sendmail %r problem, which can be easily fixed).

But if it is not your own version (but rented one) - probably you must to ask your PSA owner before.

There was no problems with upgrade from 1.3.1 to 2.5. Except you must to buy the new license.
