If you get
fatal: git-http-push failed
error message while trying to push you changes to remote WebDAV repository, make sure you have you login and password in your Git config file. Like this:
[remote "origin"] fetch = +refs/heads/*:refs/remotes/origin/* url = http://username:password@git.repository.url/repo.git
The solution was found on Stackoverflow.
curl -X OPTIONS --verbose example.com
By default ProFTPd server on Centos 5.9 tries to resolve current hostname to get IP address to bind. So if it fails if you hostname doesn’t resolve. To make it listen the socket on your IP add this line to your configuration file:
DefaultAddress 192.168.1.1
It will do the trick. Just change it to your actual IP.
Probably, it’s one of the most common tasks: running some scripts as another user and not being root. Here’s a solution.
1. Run visudo. If you don’t have it make sure you have sudo installed.
2. Add next line:
myuser ALL=(anotheruser) NOPASSWD: /home/anotheruser/bin/script.py
3. Run:
sudo -u anotheruser /home/anotheruser/bin/script.py
To remove empty lines run:
sed '/^$/d' /home/dandelion/itsfile.txt
To remove lines matching the pattern:
sed '/patter/d' /home/dandelion/itsfile.txt
Add -i option to remove in a file itself, instead of printing the output to stdout.
sysctl -w net.ipv6.conf.all.disable_ipv6=1
If you don’t have this in your sysctl.cnf after reboot IPv6 will be enabled again.
This is how you can add put you webisite working under Apache web server into the maintenance mode. Note that you need to have mod_rewrite enabled.
RewriteEngine On
RewriteCond %{DOCUMENT_ROOT}/maintenance.html -f
RewriteCond %{REQUEST_FILENAME} !/maintenance.html
RewriteRule ^.*$ /maintenance.html [L]
If the page maintenance.html exists all requests will be rewritten to it.
If you encounter en error:
make: g++: Command not found make: *** [kb.o] Error 127
while trying to update your Ruby gems on Centos, it means that you don’t have C++ compiler installed. Here’s how to fix it:
yum install gcc-c++
SecRule REMOTE_ADDR "@ipMatch 192.168.1.1/32" "id:'200007',phase:1,nolog,allow"
By default PHP exposes it’s version:
curl -vi localhost
< HTTP/1.1 200 OK < Server: nginx/1.0.15 < Date: Fri, 01 Feb 2013 23:19:48 GMT < Content-Type: text/html < Transfer-Encoding: chunked < Connection: keep-alive < Keep-Alive: timeout=64 < X-Powered-By: PHP/5.4.8
As you can see just by running GET requst you are able to get nginx and PHP version on the server:
Server: nginx/1.0.15 X-Powered-By: PHP/5.4.8
To disable it modify your /etc/php.ini file:
expose_php = Off
As well as nginx’ http section:
server_tokens off;
And if you use Apache:
ServerTokens Prod
