r3032: Somewhat stricter syntax for binding strings:
[] is now mandatory : after the hostname is no longer allowed examples of allowed binding strings: ncacn_np:myhost[samr] ncacn_ip_tcp:10.0.0.1[1045] ncacn_ip_tcp:2001:7b8:37b:1:210:dcff:fecb:a9e3[1024,sign,seal] ncacn_np:myhost ncacn_ip_tcp:192.168.4.2 308FB580-1EB2-11CA-923B-08002B1075A7@ncacn_ip_tcp:192.168.4.2 308FB580-1EB2-11CA-923B-08002B1075A7@ncacn_ip_tcp:192.168.4.2[,print] Note that the last two lines are not recognized by smbtorture as a binding string yet. dcerpc_parse_binding() does accept them though. (This used to be commit c15862e778507287bddef7967383d4b5d22eaee9)
