Hi, and help!, I've had to make a quick move of a web/mail/dns server. An involved story, but the old network is moving and the router was moved. I have use of the existing IP numbers for a bit, and need to use these until I can change them through the internic. I've physically moved the server to another ethernet with a different gateway and want to know how (if possible!) to set this up. The web server is most important, although no one is paying for this yet... At first I just tried adding a new gateway, but that didn't seem to work. What I've tried so far is bind an ip # from the new net to the interface. I can telnet to this ip number from the new network. The default gateway is now 205.185.169.1 (a cisco 2500) Do I need to add a route from the cisco to the old numbers? How? Speaking of which, the numbers are 206.250.85.99 to x.x.x.109. I'm using fbsd 2.2.2-R Parts of rc.conf, rc.local and /var/log/messages follow. If this can be done at all any help is appreciated. tia, Riley (Note- most of the network portions of rc.conf and rc.local were configured by someone else--I'm a bit new to this! ) Here's the pertinent part of rc.conf: ### Basic network options: ### hostname="charmed.wilshire.net" # Set this! nisdomainname="NO" # Set to NIS domain if using NIS (or NO). firewall="NO" # Set to firewall type or NO for none. tcp_extensions="YES" # Allow RFC1323 & RFC1544 extensions (or NO). network_interfaces="ed1 lo0" # List of network interfaces (lo0 is loopback). ##old network 206.250.85.0 #ifconfig_ed1="inet 206.250.85.80 netmask 255.255.255.0" ##net network 205.185.169.0 ifconfig_ed1="inet 205.185.169.120 netmask 255.255.255.0" ifconfig_lo0="inet 127.0.0.1" # default loopback device configuration. ### Network daemon (miscellaneous) & NFS options: ### syslogd_enable="YES" # Run syslog daemon (or NO). syslogd_flags="" # Flags to syslogd (if enabled). inetd_flags="" # Optional flags to inetd (always enabled). named_enable="YES" # Run named, the DNS server (or NO). named_flags="-b /etc/namedb/named.boot" # Flags to named (if enabled). kerberos_server_enable="NO" # Run a kerberos master server (or NO). rwhod_enable="NO" # Run the rwho daemon (or NO). amd_enable="NO" # Run amd service with $amd_flags (or NO). amd_flags="-a /net -c 1800 -k i386 -d my.domain -l syslog /host /etc/amd.map" nfs_client_enable="NO" # This host is an NFS client (or NO). nfs_server_enable="NO" # This host is an NFS server (or NO). weak_mountd_authentication="NO" # Running PCNFSD / other non-root nfsd (or NO). nfs_reserved_port_only="NO" # Provide NFS only on secure port (or NO). rpc_lockd_enable="NO" # Run NFS rpc.lockd (*broken!*) if nfs_server. rpc_statd_enable="YES" # Run NFS rpc.statd if nfs_server (or NO). portmap_enable="YES" # Run the portmapper service (or NO). portmap_flags="" # Flags to portmap (if enabled). xtend_enable="NO" # Run the X-10 power controller daemon. xtend_flags="" # Flags to xtend (if enabled).
