After cleaning off my drive chain, I’d decided to try a different dry lube.
Normally, my dry lube of choice is Squirt. An issue I had with squirt is one of muck,although the drive chain stays cleaner as a whole with dry lube, squirt tends to bunch up in areas with a thick mucky gloop. This often needs poking out from the chainring and jockey wheels. When dry Squirt leaves the chain slightly sticky. Rock N roll gold drys completly dry. No sticky feeling on the chain.
The proof however will be in the ride, which I’m planning a little later today. Will shifts be as crisp with this as they where with squirt? Will chain noise be evident? Only one way to find out!
Tired of seeing Chinese IP addresses in my server logs trying SSH access, I decided to completly block it off.
Easy way todo this? Yup.
cd /home/michael/System\ Scripts/Sineo_IPTABLES_Block/
sed -i 's/INPUT/SINEO/g' /home/michael/System\ Scripts/Sineo_IPTABLES_Block/rc.firewall.sinokorea
sed -i '/iptables -A SINEO -m state --state ESTABLISHED,RELATED -j ACCEPT/d' /home/michael/System\ Scripts/Sineo_IPTABLES_Block/rc.firewall.sinokorea
chmod +x /home/michael/System\ Scripts/Sineo_IPTABLES_Block/rc.firewall.sinokorea
sudo /home/michael/System\ Scripts/Sineo_IPTABLES_Block/rc.firewall.sinokorea
This will download a formatted list of chinese and Korean IP addresses, change the iptables chain to point to a new chain rather than the input chain, remove the now pointless established rule, and install the chain. Obviously, change the file paths to suit your structure.
It will however, require root to install the chain.
