[rancid] RANCID no longer working with MikroTik RouterOS 6.49 and 7.1rc3 and 7.1rc4

[Michael Ducharme]

Hello,

Unfortunately, that does not fix it, and neither does "network" or "dumb".
Something that I might suggest is that you install the free CHR (cloud
hosted router) as a VM rather easily, as long as you have a hypervisor, and
test against that.
