This does something essentially equivalent to showoff.io if you have a publicly facing server...

show

# Usage: show <local-port> <subdomain>
function show() {
    DOMAIN=".tekacs.com"
    REMOTE="$2$DOMAIN"
    ssh -tR 1080:127.0.0.1:$1 vps "sudo ssh -Nl \$USER -L $REMOTE:80:127.0.0.1:1080 localhost"
}

I really want to use this, but I'm getting this error:
ssh: Could not resolve hostname vps: nodename nor servname provided, or not known
Also, how can I modify this if my username on my vps is different from my username on my laptop?

Hi - a few pointers, which I should have put in at the time but I hadn't quite got around to...

The easiest option is to put the following in your ~/.ssh/config file:

Host vps
    HostName <server address>
    User <server username>

If you don't want to (or can't) do this, then the following will work:

SERVERUSER="<server username>"
ssh -l $SERVERUSER -tR 1080:127.0.0.1:$1 <server address> "sudo ssh -Nl \$SERVERUSER -L $REMOTE:80:127.0.0.1:1080 localhost"

Thanks for the response. Admittedly, I'm quite new to dealing with bash files and servers. Here's what I've got now:

function show() {
  SERVERUSER="root"
  VPS="66.228.41.55"
  DOMAIN=".*****-**.members.linode.com"
  REMOTE="$2$DOMAIN"
  ssh -l $SERVERUSER -tR 1080:127.0.0.1:$1 $VPS  "sudo ssh -Nl \$SERVERUSER -L $REMOTE:80:127.0.0.1:1080 localhost"
}

Returns: Could not resolve hostname sn.*****-**.members.linode.com:80:127.0.0.1:1080: Name or service not known. I don't know if this is a problem with the script or if it's a problem with the way I set up my Linode.

Ok, a few things - firstly, if you insist on logging in directly as root to the server (a strategy I wouldn't suggest, in favour of making a new user account on the server with the same name as your local account and just using the original script - search Google for instructions on how to add users with "useradd") then the command can be quite vastly simplified to: ssh -l root -R $REMOTE:80:127.0.0.1:$1 $VPS (again, I _really_ recommend adding a new user and following the original method instead of using this simplified command, for security reasons...) Also, I should point that you probably want a public-facing domain to use (which is what you put in $DOMAIN) (set up with Linode DNS Manager) rather than your Linode member subdomain - if you're going to go with that, DynDns will probably serve you rather better... I'm afraid I'm going to be disappearing after this e-mail, I should point out, so any further comments will have to be from others and also, most of the things that I suggest above are more far reaching than changes to the script. As such, if you'd like any more help with this my very best suggestion would be to consider http://serverfault.com/, which has a very, very helpful community who might be able to lead you through all of these steps... ## I hope this helps!
