Firewall configuration for redis-cli

[Rohit Singh]

I have a redis server running in default port. It is running as system user 'redis' not root. I also have it setup to use password. It binds to 0.0.0.0 so should be listening properly.

I am trying to connect to it from a remote VM. This VM has firewall that locks down pretty much everything.

This connections from remote VM times out. I have port 6379 open for communication both ways on remote VM for all ip address

if I turn firewall down on remote VM it works.

I see this in strace

connect(3, {sa_family=AF_INET, sin_port=htons(6379), sin_addr=inet_addr("9.3.169.160")}, 16) = -1 EINPROGRESS (Operation now in progress)

poll([{fd=3, events=POLLOUT}], 1, -1)   = 1 ([{fd=3, revents=POLLERR|POLLHUP}])

getsockopt(3, SOL_SOCKET, SO_ERROR, [12884901998], [4]) = 0

close(3)                                = 0

write(2, "Could not connect to Redis at ", 30Could not connect to Redis at ) = 30

write(2, "9.3.169.160:6379: Connection tim"..., 399.3.169.160:6379: Connection timed out

) = 39

-bash-4.1# iptables -nL | grep 6379

ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           tcp dpt:6379 

ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           tcp spt:6379

There is no telnet, but if I try wget that also does not work.

What ports should I open on remote VM for this communication to work?
