Trick program into running in foreground?

[yifanlu]

I have this weird program: dns2tcpc (creates a dns tunnel). I would like it to run at startup. However, I found that the program doesn't work when backgrounded!

EX: dns2tcpc -z dns.domain.com -l 8888 208.67.222.222
Works, and I can use SSH to port 8888.

However, if I try to background it, like: dns2tcpc -z dns.domain.com -l 8888 208.67.222.222 &
Then trying to connect to SSH won't get any response

Now, I know this is a bug in dns2tcpc, and I really don't feel like compiling it or anything (I may have to), so is there any way to "trick" an application into thinking it's running in the foreground (like typing the command from the terminal window)? (Bonus if no addition installation is required)

Use the shell command fg [jobspec] where the optional jobspec argument would be the particular job that you want to run in the foreground. Normally you would not need a jobspec argument unless you started other background processes after the one you want to move to the foreground.

Thanks for the reply. Unfortunately, it didn't work. Nevertheless, I found the solution. It's pretty hacky, but it works:

screen -dmS dnstunnel dns2tcpc -f /etc/dns2tcpc.conf 208.67.222.222

It creates a screen session, launches the command, and detaches.
