Hi tech@, Assume I use netcat with UNIX-domain socket, and there is no temp_socket. Launch the server:
# ./nc -U -l temp_socket It works normally. But after netcat exits, launch it again: # nc -U -l temp_socket nc: Address already in use The only method seems to delete temp_socket. I am not sure this behavior is as expected, and come out following patch may fix this issue, thanks! diff --git usr.bin/nc/netcat.c usr.bin/nc/netcat.c index 341e7e50485..3b2150a01dc 100644 --- usr.bin/nc/netcat.c +++ usr.bin/nc/netcat.c @@ -749,6 +749,9 @@ unix_bind(char *path, int flags) return -1; } + if (lflag) + unlink(path); + if (bind(s, (struct sockaddr *)&s_un, sizeof(s_un)) < 0) { save_errno = errno; close(s); -- Best Regards Nan Xiao
