Sorry, I meant by "anything else" -- any other tool, e.g., ssh,
traceroute, nmap, telnet, etc.

[Heh. I started to write "and where is that machine located?" before I
realized it wasn't a machine name.]

FROM            TO              PING    SSH
linus           linus           Y       Y
linus           hendriena       Y       Y
linus           gypsy           Y       N
hendriena       linus           Y       Y
hendriena       hendriena       Y       Y

gypsy           hendriena       Y       Y
gypsy           gypsy           Y       Y

And the error is "No route to host".

That shouldn't be the issue if it's a routing issue.

If it's a "it don't work", well, check your iptables (and SELinux?)
settings on gypsy.

Good.

I'm starting to wonder if there's an ARP issue involved... I deal with
those so rarely I forget what the errors look like.
