wierd log droppings from Apache 1.2b4 ftp proxy?

Post by Jeff Dougla » Sat, 08 Feb 1997 04:00:00



I run Apache 1.2b4 and proxy ftp via the http port by setting the
following options in httpd.conf:

ProxyRequests On
ProxyRemote ftp http://gatekeeper.foo.com:80

All web browsers are then setup to use port 80 to proxy ftp.
When I do this I see output similar to the following in a log file:

Feb 6 10:14:26 gatekeeper kernel:
Feb 6 10:14:26 gatekeeper kernel: tcp_ack: seq 53d6861a ack e2e24f65
Feb 6 10:14:27 gatekeeper kernel: Ack past end of seq packet.
Feb 6 10:14:27 gatekeeper kernel:
Feb 6 10:14:27 gatekeeper kernel: tcp_ack: seq 53d6861a ack e2e24f65
Feb 6 10:14:30 gatekeeper kernel:
Feb 6 10:14:30 gatekeeper kernel: tcp_ack: seq 53d6861a ack e2e25acd
Feb 6 10:14:30 gatekeeper kernel:
Feb 6 10:14:30 gatekeeper kernel: tcp_ack: seq 53d6861a ack e2e2603c
Feb 6 10:14:34 gatekeeper kernel: rcv_ack_seq: 53D6861B==53D6861B,
                                   acked_seq: E2E2603C==E2E2603C

Sometimes there is quite a lot of it. ftp seems to be working but I
wonder about these tcp/ip packet problems. Anyone have some insight?

Regards,
