I manage a website which runs on the cpanel/whm interface and was wondering if there was anything my host could do to prevent DoS attacks on the server...at the moment we are having huge DoS attacks on our website therefore taking the whole website down for quite long periods of time.
My host just seems to be manually blocking the DoS'ers IP's manually but this is just too tedious and not efficient enough.
Is there any program for example that he can install which will block andy ip which sends a certain amount of requests within a given time period?
I am receiving around 7.000 emails from different sources with the subject “Undelivered Mail Returned to Sender” or similar.
It seems someone is using an alias to my email address to send huge amounts of spam. I have checked the mail queue in WHM and the emails are not there. I have turned on the SMTP Tweak in security center, but that doesn’t seem to work.
I have no idea if this person is using my server to send massive amounts of spam,
What I have noticed is that most emails return to msxf@mydomain.com so is there a way to block this?
I have configured qmail+spamassassin. It working find but still I have 2 problem. I am receiving spam mails from my own account to my own account e.g. from=info@domain.com to info@domain.com. How can I block this spam?
I'm trying to use spamfilter to block mail from specific address, adding this e-mail to spamfilter in mail account settings, but it doesn't work. In logs I see:
spamc[13430]: skipped message, greater than max message size (256000 bytes).
My customer has an external facing Apache server that is acting as a reverse proxy to two internal applications. They have:
- external addresses for each app which resolve to different ip addresses, so app1.their_domain.com and app2.their_domain.com resolve to 77.3.170.10 and 77.3.170.11 respectively. - the Apache server has two network interfaces with ip addresses 192.168.10.10 and 192.168.10.11 - the external ip addresses resolve to the above internal addresses - the firewall between the Apache server and the internal app servers is configured to allow traffic from 192.168.10.10 to reach app_server1, and traffic from 192.168.10.11 to reach app_server2, both using port 7777.
I have configured a virtual host in httpd.conf for each ip, i.e.
This works fine in that the external address are being routed to the correct application, however the firewall is blocking requests to the second app as it appears the requests are coming from the Apache servers 'primary' ip address 192.168.10.10 instead of 192.168.10.11.
Is it possible to send requests using the ip address from the relevant VirtualHost?
we compile a php 4 with all the modules that we require. However, after a day or so, it automatically becomes a fresh compilation of php 5. We then recompile to php 4, but same thing, after a day or so it become php 5 again. We've checked cron, and there's nothing to do with recompiling php.
I want to redirect a website to a particular URL so that the address bar shows the same URL and not the destination URL. I know it is possible via URL masking, however, I want it in such a way that whenever somebody clicks on any link in the website, the address bar should still show the original URL. To put it in simple words, Suppose I want to redirect [url] to [url]. Now if there is a link named contact/index.htm and somebody clicks on it the address bar should display [url]and not redirect to [url]
How can it be possible using URL Rewrite method in .htaccess file?
- I can't access the webserver - I'll try to restart httpd, and I'll get
Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:443
To fix this, I run
[root@www1 ~]# lsof -i tcp:443 COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME perl 11307 apache 4u IPv6 476943447 TCP *:https (LISTEN)
There is always leftover process that is causing the restart to fail. Once i force kill the process, I am able to restart httpd properly.
Now it is ok if this just occurs once in a while, but this problem keeps repeating itself almost everyday at 4am server time (cron time?). What can I do to permanently fix this?
I'm not 100% sure where to ask this, so feel free to move it to a more appropriate place if necessary.
At present, my webhost provides me with some statistics about my website through "AWStats". The problem I have is that if I don't update the 'stats' everyday, then I lose that day's records and I have a gap in my statistics.
is there a way I can automate the updating of the AWStats?
I use rfxnetworks.com/sim.php on my cpanel server and it all worked fine until the last week where each morning 6am GMT I get a status warning telling me that XINET was down and that it had to restart it.
Has something changed? Is there now something weird about XINETD and cpanel? My cpanel is stable and set to automatically update.
In fact it looks like something ALWAYS shuts it down and then SIM restarts it looking at a section of messages:-
Is there a way to automatically remove files from a folder on a schedule, say daily, and move them to the Recycle Bin? Can the Recycle Bin files be deleted daily on a schedule? If so, how?
I have Microsoft Office Professional 2007 running on a Windows 2003 Server.
I have a server in a country (Location 1) and I have my company website on it and in this country the connection is very fast but not very stable so I have the same website on another server (Location 2) as a backup server so I want to do is as the following:
- www.mywebsite.com > Website loads from my Server at Location 1.
- Server at Location 1 is down.
- www.mywebsite.com > Website loads from my Server at Location 2.
- Server at Location 1 is back working.
- www.mywebsite.com > Website loads from my server at Location 1.
How can I do this in DNS options?
Also Can you suggest an easy way to do realtime backup from the server at Location 1 to Location 2 so that any changes made on Location 1 are cloned on Location 2?
I am facing a problem with one of my Windows 2003 servers. The websites hosted on the server use IUSR_computername user for anonymous authentication for the websites. Please note that I have anonymous authentication disabled for FTP. The problem is that every night the IUSR_computername user gets deleted automatically and all the websites start asking for password as there is no user for the anonymous browsing of the websites. I checked the event log, but could not find anything. How do I find why the user is getting deleted automatically?
We are facing apache problem on one of our server.
It is getting restarted automatically within 30 seconds.
Below are the logs.
Please let us know the solution if any asap.
