I need to change the host name of a NAS drive because I used an "invalid" character in it's name. (Nothing in my network seems to care except a QNAP NAS that accepts only regerously conforming DNS names. So I need to change DS281_1 to DS218-1 if I want my QNAP NAS to talk with my Synology NAS..
I temporarily want both the old and new name resolve to the DHCP-supplied IP address. So I think I want to add a CNAME record to the router's DNS server's config.
I know just enough about DNS servers to be dangerous. I don't know enough about the ASUS router, Merlin, or Linux to know if I'm being dangerous or not.
I've looked at "Custom domains with dnsmasq" at https://github.com/RMerl/asuswrt-merlin.ng/wiki/Custom-domains-with-dnsmasq
That doc says "Enable JFFS custom scripts and configs". Since I've never enabled it before, do I also need to "Format JFFS partition at next boot". If "yes", does that option turn back off after the next boot? Is there any downside or danger in turning on JFFS?
That doc has the user (creating and) editing "/jffs/configs/dnsmasq.conf.add". Does that file contain additions to what Merlin already uses, or does it override the existing definitions so I need everything needed to make the DNS server work? (I assume the "add" in the file name implies additions, but I've been wrong before.)
I think I just want to add (if I make the router change before renaming the NAS)
--cname DS218-1,DS218_1
or (if I make the router change before renaming the NAS)
--cname DS218_1,DS218-1
