I have modified /usr/jails/jail/etc/hosts, /usr/jails/jail/etc/resolv.conf and usr/jails/jail/etc/ssh/sshd_config. I note however that there are a very large number of configuration files throughout the jail that contain a literal value of 127.0.0.1. Do all of these need updating? Under /usr/jails/jail/usr/local/etc/ there are also files that contain 127.0.0.1 as literal values, /usr/jails/hlldns02/usr/local/etc/rc.d/named for example. How does one handle rc.d scripts that specify 127.0.0.1? If these all require manual alteration then why is not localhost used instead? Then one would only need alter the hosts file. -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail Do NOT open attachments nor follow links sent by e-Mail James B.
