|
|
|

|
|
|
|
|
LOGDIR=${HOME}/goseederlogs/
|
|
|
|
|
|
|
|
|

|
|

## RUNNING AS NON-ROOT
|
|
|
|
|
|
|
|
|
|
Typically, you'll need root privileges to listen to port 53 (name service).
|
|
|
|
|
|
|
|
|
|
One solution is using an iptables rule (Linux only) to redirect it to
|
|
|
|
|
a non-privileged port:
|
|
|
|
|
|
|
|
|
|
$ iptables -t nat -A PREROUTING -p udp --dport 53 -j REDIRECT --to-port 5353
|
|
|
|
|
|
|
|
|
|
If properly configured, this will allow you to run dnsseeder in userspace, using
|
|
|
|
|
the -p 5353 option.
