 Standard practices say no non-root process gets to talk to
 the Internet on a port less than 1024. Anyway I suggest you
 to start Cloud Commander as non-root. How it could be soulved?
 There is a couple easy and fast ways. One of them is port forwarding by iptables.
-```
-iptables -t nat -L # look rules before
-@:/tmp/cloudcmd (dev) $ iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 8000
-@:/tmp/cloudcmd (dev) $ iptables -t nat -A PREROUTING -p tcp --dport 443 -j REDIRECT --to-ports 4430
-iptables -t nat -L # look reles after
-```
-You should see somethins like this (8000 and 4430 should be in config as port and sslPort)
-```

-REDIRECT   tcp  --  anywhere             anywhere             tcp dpt:https redir ports 4430
