Notes

network/domain/dns questions

  • pod private wiki requires a domain
  • that requires network interfaces and ip addresses to be set up

tinc

  • installing tinc natively, whole point is to avoid fuss
  • doesn't feel particularly secure, but it's all public/private key infra, soooo
  • tinc is more limited, requires clients to have tinc installed and keys copied
  • to get around that, create dorky socks proxy server that handles traffic to the wiki

bespin setup:

  • bespin runs own dns server
  • bespin.charles points to itself
  • bespin.charles/wiki is wiki endpoint
  • bespin connects to dorky via tinc, 10.6.0.10
  • bespin has a self-signed ssl certificate for bespin.charles

dorky setup:

  • dorky has a dns server bound to tinc interface - tinc dnsmasq
  • dorky.charles points to itself
  • dorky gets connection from bespin via tinc, 10.6.0.1
  • dorky has a charlesreid1.party certificate
  • dorky runs a socks server
  • dorky forwards packets between socks tunnel and tinc tunnel
  • dns requests forwarded thru socks tunnel are handled by tinc dnsmasq

Tinc on bespin and dorky

On bespin (behind NAT):

$ cd /etc/tinc/master

$ cat tinc.conf
Name = bespin
AddressFamily = any
Mode = switch
ConnectTo = dorky

$ cat tinc-up
#!/bin/sh
ifconfig $INTERFACE 10.6.0.10 netmask 255.255.0.0

$ cat tinc-down
#!/bin/sh
ifconfig $INTERFACE down

$ ls hosts/
bespin
dorky

On dorky (public IP):

$ cd /etc/tinc/master

$ cat tinc.conf
Name = dorky
AddressFamily = any
Mode = switch

$ cat tinc-up
#!/bin/sh
ifconfig $INTERFACE 10.6.0.1 netmask 255.255.0.0

$ cat tinc-down
#!/bin/sh
