Hello!
I'm pretty sure that I'm running into a security blockade. I have
several small example sockets programs which have compiled and worked in
the past on other platforms. However, they are not working under SL
6.3, even when I change ports multiple times.
I have:
* disabled SELINUX (I first tried setenforce 0 as root to make it
simply permissive, but no luck, so I disabled it instead)
* turned iptables off: /etc/init.d/iptables stop
Still, after having done both of these, I can't get a simple socket and
client example to work. The /var/log/messages file simply shows my
shutting off of iptables.
Is there another thing that I can do to get some simple sockets examples
to work? I figure once I have located the problems, I can begin to
attack the rules needed to get it to work.
Upon revisiting this problem:
* disabling selinux on my laptop (with SL6.3) did result in my
example sockets programs to work on my laptop. Not sure why it didn't
work before, although perhaps I only tested this disabling with the desktop.
* disabling selinux on my desktop (with SL6.3) still has
difficulties. The sockets programs hang on accept()/connect() calls.
The major difference that I see between the two is that the desktop is
running SL6.3 in a VM (vmWare 7.0).
FYI - I ran the sockets program using sockaddr_in although both the
server and client resided on the same machine.
Anyway, looks to me like there's something awry with the vmWare+SL6.3
combo which is blocking the socket connections from occurring.
