Hi. I've just compiled 1.0 on a SunOS 4.1.3u1 machine. This version of SunOS shares a bug with early versions of Solaris, in that gethostbyaddr/gethostbyname does not normally return the fully qualified domain name. A way to force gethostbyname to return the FQDN is to append a trailing dot to the hostname returned by gethostbyaddr. Of course, this may not appropriate in all contexts, for example, if the machine does not use NIS (which in its turn can be set up to call DNS for name resolution.) No doubt this can be fixed in a simple and elegant manner. For example, there is no problem if gethostbyaddr returns a host name that contains at least one dot. If there is no dot in the returned host name it's possible that appending a dot causes gethostbyaddr to fail (I haven't checked this). The small patch below shows how I dealt with it; I'm certain you can improve on it ;-) 447a448,453 > #define RWI > #ifdef RWI > host1 = malloc(strlen((char *) hp->h_name) + 2); > strcpy(host1, hp->h_name); > strcat(host1, "."); > #else 448a455 > #endif 458a466,469 > #ifdef RWI > free(host1); > host1 = Sstrdup((char *) hp->h_name); > #endif //Raymond.
