...etermined. I am using Solaris 8 with ssh 3.4p1, and this piece of code: debug3("Trying to reverse map address %.100s.", ntop); /* Map the IP address to a host name. */ if (getnameinfo((struct sockaddr *)&from, fromlen, name, sizeof(name), NULL, 0, NI_NAMEREQD) != 0) { /* Host name not found. Use ip address. */ log("Could not reverse map address %.100s.", ntop); return xstrdup(ntop); takes like 30 to 60 seconds to run if you have dns listed in your nsswitch.conf, which in many cases is needed....
