Re: [MirageOS-devel] Problem http reply with mirage-static and mirage-www

[Luis Oviedo García <psxlco@xxxxxxxxxxxxxxxx>]

Wireshark reports unseen ACKed unseen segments and duplicated acks,  (attached 
:) wondering if it is only me who sees this weird behaviour.
Using the latest version (2.4.3), will try as suggested.

Kind regards

The first ACK of the unseen segment looks really weird to me -- did
wireshark report drops? What version of mirage-tcpip are you using? If
the latest, might be worth trying to back off (via opam pin) as
there've been changes recently that may be having subtle effects...

(Possibly also easier for others to read if you just capture a binary
.pcap file and attach that -- quite hard to parse the text output in
an email like that, for me at least!)
