I'm totally just guessing here - no real experience in this arena - but you might try running tunnel connection as a child process (or maybe the parent spawns a child to run telnet, and then the parent opens the tunnel? I'm clueless on that).

Anyway it sounds like the program hangs because it's waiting for i/o on one connection, and so cannot do anything on the other. In my limited experience using SSH tunnels (interactively only, never via scripts), the tunnel ssh connection is always running separately (e.g. in another shell) from whatever process is supposed to actually do stuff using the tunnel.

    [james28909]: how come it is so easy for me to not care what others think while others will mute themselves because they are scare they will be called ignorant or stupid
    [james28909]: do you relize how shrodinger felt when he was describing the quantum world? what about neils bohr?
    [holli]: it's probably the autist in you. I am like that too, no fucks given about what others think about me
    james28909 checks, yep... htere are no fucks to give
    [james28909]: another thing i am sick of is hurting others feelings
    [1nickt]: james28909 You lost me a bit when you said "show me evolution from intelligence to ignorance". I guess we would have to define the terms, but as I look around at my species and how we are destroying our habitat ...
    [james28909]: seems like a person cant even have a belief without hurting someones feelings. i never said my way is the only way. i just said i have pretty good scientific evidence, and then asked for opposing side to present evidence
    [james28909]: was downvoted and left without a reply. go figure
    [holli]: but then you DO give a fuck
