More on the sysinstall hang; I can't tell if this is an FTP proxy bug or a sysinstall bug, since I didn't get to snoop the control connection. I see: DEBUG: send <PORT 13,0,208,199,5,51> DEBUG: received <200 ...> DEBUG: send <RETR XF8632/X32html.tgz> DEBUG: Switching back to VTY1 Note no "received <150 ...>". When I tcpdump, I see window probes going from the FTP server to the client, on port 1331 aka 5,51: 22:07:01.538273 beta.3126 > fenestro.1331: . 1196817521:1196817522(1) ack 1117785547 win 24576 22:07:01.538509 fenestro.1331 > beta.3126: . ack 1196817521 win 0 (DF) 22:08:01.541976 beta.3126 > fenestro.1331: . 1196817521:1196817522(1) ack 1117785547 win 24576 22:08:01.542215 fenestro.1331 > beta.3126: . ack 1196817521 win 0 (DF) so it looks like sysinstall is hung waiting for the response to the "RETR" and not reading any of the data that's arriving on the data port. I guess I'll start another sysinstall and "tcpdump -w" the FTP control connection. (But of course the next one probably won't hang...) Bill
