Just an FYI, you won't see the environment access with strace. Strace
works on system calls, and since reading or writing the environment
doesn't involve a call to the kernel, you won't see that there. You
can see the environment that the program is called with if you add the
-v option to strace however.
BUT, you should see at least an attempt to connect() to something. I
mean, how can it claim that it cannot connect to an X server without
even trying??? :-) For example, when running xclock locally, I see
these:
socket(PF_FILE, SOCK_STREAM, 0) = 3
...
connect(3, {sa_family=AF_FILE, path="/tmp/.X11-unix/X0"}, 19) = 0
When running over an ssh connection, I have:
socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 3
setsockopt(3, SOL_TCP, TCP_NODELAY, [1], 4) = 0
...
setsockopt(3, SOL_SOCKET, SO_KEEPALIVE, [1], 4) = 0
connect(3, {sa_family=AF_INET, sin_port=htons(6010),
sin_addr=inet_addr("127.0.0.1")}, 16) = 0
You should see something similar.
