The network of my company has banned some ports. I want some software to
detect which port could be used. Any software to recommend? Green version
prefered. Thanks very much!

I am afraid that before you find open ports, you will be found by security
team of your company:)

two possibilities
1) wide open on this port (then you may use putty to ssh out, which
potentially open all possibilities)
2) I've seen some weird fws check addl keepalives, keep shutting down the

abcd
