KL ITS running under pdp10-kl Cannot do FTP

[eswenson1]

I built a pdp10-kl instance, and while I can access it via supdup via chaosnet or tcp/ip, and can access telnet via both chaosnet and tcp/ip, I cannot use FTP inbound to ITS. Attempts to access the ITS FTP server, via, say ftp or telnet (for testing) results in no response from ITS.

My pdp10-kl run script includes:

set imp enabled
set imp host=192.168.2.100
set imp ip=172.16.0.4/24
set imp gw=172.16.0.2
at imp nat:gateway=172.16.0.2,network=172.16.0.0/24,tcp=5023:172.16.0.4:23,tcp=5021:172.16.0.4:21,tcp=5095:172.16.0.4:95

Again, I can do telnet 127.0.0.1 5023 to telnet into the KL instance. And I can do 'supdup 127.0.0.1 5095' to supdup into the instance. But if I do a 'telnet 127.0.0.1 5021' (to access the FTP server), I never get any FTP banner.

I do get the FTP banner if I use pdp10-ka to access a KA instance.
