hallo ng,
i have a server, running on suse linux 8.0 with the iptables-script
susefirewall2. the maschine is connected via dsl to inet. all pcs in lan
are masqueraded and routed. no problem until here.
following services run on the server:
ftp, apache with php4, ssh, smtp, mysql
my problem:
a have php-scripts, that open a socket on port 80 on different webservers in
the inet. but this doesn't work.
it's not more than $fp = fsockopen ($host, 80);
i have tested the little script on many other servers, where it worked fine.
so it seems that this is not a problem of apache or php.
when i use ssh to login and type "lynx www.abcdef.de", lynx shows the page.
so why does the webbrowser get a connection to port 80 of other maschines
and php not?
can somebody help me please?
here the configuration of susefirewall2:
