Question

Problems in IPTABLES in CentOS x64

I recently updated my CentOS 6.x x64 Droplet, against the Heartbleed virus, by following instructions in DigitalOcean community (https://www.digitalocean.com/community/articles/how-to-protect-your-server-against-the-heartbleed-openssl-vulnerability). After doing the update, the IPTABLES configuration are all gone and I am unable to configure the IPTABLES. Upon issuing the command
iptables -A INPUT -p tcp --tcp-flags ALL NONE -j DROP

I get the below error /lib64/xtables/libxt_tcp.so: /lib64/xtables/libxt_tcp.so: file too short iptables v1.4.7: unknown option --tcp-flags' Try iptables -h’ or ‘iptables --help’ for more information.

Seems the ‘yum update’ has screwed some libs. Can someone please help how to correct the error? This is draining me!

Thanks, Sam

@Marinos - Thanks for the response. I re-imaged my droplet to save time. It was taking too much of me to get it working.

Can you post the yum log file?
