What do I need to do to change the ip address of the ISPConfig server so it will continue working properly? thank you!
No mention of the Operating system involved ... This may not work on your OS, but here goes: Change files /etc/hosts and /etc/network/interfaces search for other configuration files where the IP may be: grep -r 11.22.33.44 /etc you may also need to change name server and gateway if new IP from other network change name server records, also reverse name service change settings in ISPConfig panel, System | Server IP-addresses, then do Tools | Resync Tools | Resync | All Services At least on multiserver ISPConfig setup, dbispconfig database has IP-address of hosts, those need to be changed.
if you're on a recent ubuntu, especially a vps, instead of /etc/network/interfaces, it'll probably be /etc/netplan/50-cloud-init.yaml
Sorry. Using Ubuntu 20.04 Apparently not even in interfaces as nhybgtvfr already stated but only in /etc/netplan/00-installer-config.yaml: /etc/netplan/00-installer-config.yaml: gateway4: /etc/netplan/00-installer-config.yaml: nameservers: I suppose you mean the normal DNS records for the domains? (I don't run them on the server) I only have a small standalone setup. Hope it is actually this simple. Thanks a lot.
