I've got some problems with our Sun OS (SOS) 4.0 machines and DDN services. They are all RoadRunners, but I've seen the same problem on a Sun-3 running SOS 4.0. The first problem is that I can't ftp into a 4.0 SOS machine unless I use the user name root. All other accounts are denied access. The local service people say there is a memo about ftp security being on by default but can't tell me how to undefault it. I can't find any mention of ftp security in the manual pages except for the old "anonymous" remarks. I haven't been able to find an analogue to ftpusers either. The second problem is that I can't get the ftp and telnet programs to use the name domain server. Named runs fine as does nslookup and the MX version of sendmail, but ftp and telnet tell me that any host not in the yellow system is unknown. I'm running ypserv with the old secret -i flag just like I do on our 3.n systems but have no joy. Does anyone know if the secret flag to ypserv has changed? Mike

can't ftp into a 4.0 SOS machine unless I use the user name root anonymous ftp works fine to my Sun OS 4.0 machine, after following the setup instructions in the ftpd man page. I'm running ypserv with the old secret -i flag just like I do on our 3.n systems but have no joy. 4.0 versions of ypserv don't use the "-i" option. You have to build yp host.by* maps using the "-b" option of makedbm. (See the makedbm man page). You will probably also need a new version of ypserv from Sun which fixes a critical bug with the "-b" option. mallen@sun.com should be able to help you with this. John Larson, Xerox PARC
