zerotier device names and MTU #38

Closed barbabob closed 4 years ago

barbabob commented 6 years ago

To prevent garbage device names I must keep a file /var/lib/zerotier-one/devicemap. On a start zerotier recreates a whole bunch, and on a stop it removes ALL of it. This makes it unmanagable and it forces needles writes. Please keep some configfile(s) that can set the device name and MTU of that device. (MTU must be low to keep an ssh connection (A-NAT--NAT-B) possible.) BTW, zerotier on 18.06.0-rc1/2 and snapshot is disfunctional. I must use 18.06.0 now.

How do the device names look like? Do you connect to a lot of different networks at once?

Btw. in /etc/config/network you can add an interface section to pin a devices mac and mtu.

'ztbpafrgg3' on all devices (DIR-505 running openwrt) and even on a Raspberry Pi (1&3 running raspbian).

No. It gets hardly used because the main purpose of zerotier is emergency backdoor access. It has to be reliably present. At the moment I set the mtu by a cronjob every few minutes. I need that cronjob anyway because the zerotier process always vanishes after a while for no apparent reason. In openwrt that is. A dip in the network connection maybe?

Good to know. I'll give it a try.
