I have an Ubuntu machine, and I've been trying to set up Munin on port 4949. I have it running, and I can connect to port 4949 from the local machine, but connections from external machines keep timing out. I've already set
allow ^.*$ in the configuration, so it shouldn't refuse any connections.
If I run
lsof I get:
deployer@rc:~$ sudo lsof | grep munin /usr/sbin 31863 root 2w REG 202,1 78531 189176 /var/log/munin/munin-node.log /usr/sbin 31863 root 3r REG 202,1 6778 591661 /usr/sbin/munin-node /usr/sbin 31863 root 4w REG 202,1 78531 189176 /var/log/munin/munin-node.log /usr/sbin 31863 root 5u IPv6 42450001 0t0 TCP *:munin (LISTEN)
I can't tell if it's a firewall issue or not. How can I tell if inbound connections are successfully reaching port 4949?
