erics, September 5th, 2017 Step 1: Enable Apache status and lock it down: Make sure mod_status is being loaded:
|
1 2 3 |
shell> grep -Rn mod_status /etc/httpd/* /etc/httpd/conf.modules.d/00-base.conf:58:LoadModule status_module modules/mod_status.so |
Add support for the call just under the first DocumentRoot statement:
|
1 2 3 4 5 6 7 8 |
shell> vim /etc/httpd/conf/httpd.conf <Location /server-status> SetHandler server-status Require ip 127.0.0.1 Require ip ::1 Require ip {Your_IP_Here} </Location> |
Step 2. Prepare your environment:
|
1 |
shell> cpan YAML HTML::TableExtract |
Step 3: Create and run the status script: (See the astat contents at the bottom)
|
1 2 3 4 5 6 7 8 9 |
shell> vim /root/astat shell> chmod 755 /root/astat shell> vi ~/.bashrc ADD: alias ipw='while true; do sleep 5; /root/astat; done' shell> ipw 1.2.3.4|yourdomain.com:443|POST /wp-cron.php?doing_wp_cron=1563901063.57946491241455078125| |

erics, February 3rd, 2016 There are times when the hackers slam my servers and the load gets too high. I use a very simple bash script as a cron job to monitor the load and take action when it gets too high. The script will stop httpd, sleep for a configurable period of time (currently 3 minutes), then start […]

erics, October 16th, 2009 Got the client’s web server to accept secure connections via SSL. I configured Apache httpd.conf properly so it used the right certificate file and it finally started working. I love lsof – what a great tool. Naomi just got home. Time for some TLC for her.

So I have to deal with THAT now, instead of getting focussed time. Is driving me crazy. The data recovery has NOT been going […]

Any directive that is allowed in a directory context may be used. Directory-path is either the full path to a directory, or a wild-card string using Unix shell-style matching. In a wild-card string, ? […]
