Thanks for noticing, I verified this locally. Kermit FTP from RHEL5
on i386 works OK, but on 64-bit hardware (ia64 in this case) it doesn't
work. That's what Alpha tests are for!

If you're up for taking a look at the ftp_hookup() function
in ckcftp.c, the offending statement is:
connect(s, (struct sockaddr *)&hisctladdr, sizeof (hisctladdr))
around line 14715. Clearly something is amiss with the definition
or setup of the structs in this case. In fact, now that you mention
it, I see that the same thing happens on Mac OS X 10.6.2, also 64-bit.
I'll try to get to it pretty soon, but I have a huge backlog so "soon"
might be a few weeks; if anybody wants to pitch in before that, be
my guest!
