[question] ACE/SERVER and security

[Sun Young Geun\(선영근\)]

I'm operating ACE/SERVER. ACE/server is configured master and slave.   I have some question about security.   1. I found something in .rhosts file like that.   #cat .rhosts ++   Do they  use r-command  when master and slave communicate each other? If not, is there any problem whithout .rhosts file? I want to delete .rhosts file because it is very vulnarable in securtiy.   2. I want to comment all services except for telnet service. The inetd.conf file allows services. If I open only telnet service, is there any problem in ACE/SERVER?   Please reply to me a.s.a.p.   Happy new year !!
