Add full previews to your twitter feed on WordPress using Ozh’ Tweet Archiver

Ozh’ Tweet Archiver is a WordPress plugin that can archive your tweets on your own blog; it simply creates a new post for each tweet. Additionally, it offers converting hashtags to WordPress tags, and several other features. Nevertheless, one feature, I thought might be interesting, is to process the links on tweets and show them as a Facebook feed. Recently, I modified the code and it worked very well on my blog: Gadelkareem Tweets.

– All we need is to modify the “wp-content/plugins/ozh-tweet-archiver/inc/import.php” file as following:

Configuring vsFTPd on CentOS with different port

Check Installing CentOS 6.2 on VMware post.

– make sure SELINUX is disabled and iptables is configured for FTP

– add ftp user

adduser ftpuser -g ftp -s /sbin/nologin -d /server
#set password
passwd ftpuser

– configuration, more info

increase linux file descriptors

Check Installing CentOS 6.2 on VMware and mounting partitions with noatime posts.

This is very important performance tuning for any web server more information here

#adduser www first
ulimit -n unlimited - www
#check default number of concurrently open file descriptors 
cat /proc/sys/fs/file-max
#set the number to high value depending on server config
echo '1773914' > /proc/sys/fs/file-max
echo 'fs.file-max=1773914' >> /etc/sysctl.conf
/sbin/sysctl -w fs.file-max=1773914

Configuring iptables on CentOS

– disable SELINUX

vi /etc/selinux/config

– reboot or run

 setenforce 0

– add iptables rules

Configure sendmail to accept emails only if “from”, “to” or specific field matches

you can exclude an email address or even a host that is spamming you using the access file located in your etc directory, the bad news is that it does not support regex or even wildcards.
