...tus: NEW Severity: normal Priority: P5 Component: ssh Assignee: unassigned-bugs at mindrot.org Reporter: hektor at itc.rwth-aachen.de If an IPv6 host has no AAAA DNS entry the DISPLAY variable might contain a hexadecimal/colon address. The function x11_connect_display() in channels.c determins the "hostname" in the DISPLAY variable by searching for the *first* colon occurence (line 3550 in that file): cp = strchr(buf, ':'); This seems to be incompatible with the representation of IPv6 addresses. The resulting error produces an error mess...

Hi! Here is the patch to support tcp wrappers with x11-forwarded connections. The patch is for openssh-3.0.1p1 but it works fine with 2.9.9p2 too. I've understood that this will not be included in the official version because it adds complexity (?!) to openssh. Binding the forwarded port to localhost doesn't solve all problems. I've understood that you should also implement
