problem. One of our customers sees an issue every couple weeks where the stunnel process becomes busted. Attempts to establish a connection through stunnel to any host hang indefinitely. Interface stats indicate that stunnel sends and receives a flurry of packets--as if a TLS connection was successfully established--but the local plaintext socket connection to stunnel never passes data. For example, if attempting to run telnet over stunnel, the telnet client just sits there and doesn't write anything to the terminal. During this time the network is otherwise functioning fine.
Things that comes to my mind: * I had a mobo w/ a funny onboard ethernet I/F: after "some" networking, it needed a linux driver reload (or w$ reboot) - never knew why, * a MiM missed attack could also give this result (cli should watch arp), * Even though I'm downtown the renewal of my adsl box lease takes almost 4 minutes to "stabilize".
