Luc, I have seen this kind of weirdness before, but I mostly see it with ab (apache benchmark tool). I really have no idea. Have you tried with telnet to do a manual HTTP request ?
$ telnet localhost 1701 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. GET /random HTTP/1.1 Host:localhost:1701 HTTP/1.1 200 OK Content-Type: text/plain;charset=utf-8 Content-Length: 64 Date: Sat, 14 Jun 2014 08:58:48 GMT Server: Zinc HTTP Components 1.0 EF97C091498F3FEA3F79F65D36C40ECAFD116A68BA31F45D027DB61EBDD1579 ^] telnet> close Connection closed. You could also try using the same or a second Pharo image to do the request. $ ./pharo Pharo.image eval "ZnClient new get: 'http://localhost:8080/random'" '766EF4E6E5664EF4C5163D30125B5C35BFE2AED408835CB6D6206DF0A7A15FD ' In any case, the server socket used is normally listening on all interfaces [0.0.0.0] Sven On 14 Jun 2014, at 09:17, Luc Fabresse <[email protected]> wrote: > > > 2014-06-14 6:04 GMT+02:00 Ben Coman <[email protected]>: > Luc Fabresse wrote: >> Hi, >> >> I experiencing a strange difference between localhost and 127.0.0.1. >> >> In Pharo I do: >> >> (ZnServer startDefaultOn: 4444) >> onRequestRespond: [ :request | ZnResponse ok: (ZnEntity text: 'hello') ] >> >> In bash: >> >> $ lsof -Pi | grep Pharo >> Pharo 2718 luc 7u IPv4 0x1e64a2e9381f409b 0t0 TCP *:4444 >> (LISTEN) >> >> I perfectly listen on port 4444 from all interfaces * >> >> $ curl http://127.0.0.1:4444 >> hello >> >> $ curl http://localhost:4444 >> curl: (7) Failed to connect to localhost port 4444: Connection refused >> <- why ? >> >> localhost is correctly resolved on my mac >> $ ping localhost >> PING localhost (127.0.0.1): 56 data bytes >> 64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.044 ms >> >> I tested with other programs than Zinc to open listening sockets and it >> works. >> >> Any idea? >> >> #Luc > maybe http://sourceforge.net/p/curl/bugs/1337/ > > Humm, I use curl 7.36.0, so yes perhaps this bug fix is not integrated... > > Anyway, I was also suspecting curl but I tested with server: Apache on port > 8888 and here curl works: > > httpd 621 luc 5u IPv6 0x6ea19c1d988f10db 0t0 TCP *:8888 <-- > same as Zinc > > but both: > > curl http://127.0.0.1:8888 > curl http://localhost:8888 > > are working. > > wget always works (Apache and Zinc): > > wget -qO- http://127.0.0.1:8888 > wget -qO- http://localhost:8888 > > Thanks Max and Ben, > > Luc >
