Problem when running iptables in Ubuntu 14
I'm totally stuck with iptables and don't find the way to fix it. All started when I updated the kernel version:
1) When "ufw status", I get error
ERROR: problem running iptables: modprobe: ERROR: could not insert 'ip_tables': Exec format error
iptables v1.4.21: can't initialize iptables table `filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
2) When "modprobe ip_tables", I get:
modprobe: ERROR: could not insert 'ip_tables': Exec format error
3) I've upgraded to lastest available kernel in DigitalOcean: 3.16.0-23-generic
4) uname -r gets:
3.16.0-23-generic ; so it matches the kernel selected in DigitalOcean Control Panel
5) Have rebooted many times, to not result
Any idea on how to get this fixes is welcome.
