It is *not* out of the question.  tcping doesn't need system privileges.

Download the tcping rpm...  Then....

For example do this...

[egreshko@meimei ~]$ rpm2cpio tcping-1.3.5-7.fc18.x86_64.rpm | cpio -idv
./usr/bin/tcping
./usr/share/doc/tcping-1.3.5
./usr/share/doc/tcping-1.3.5/LICENSE
./usr/share/doc/tcping-1.3.5/README
43 blocks

Now, since I keep user specific binaries in ~/bin

[egreshko@meimei ~]$ mv ./usr/bin/tcping bin/

[egreshko@meimei ~]$ bin/tcping -t 1 imap.gmail.com 993
imap.gmail.com port 993 open.
