久々に設定してみた

導入

$ sudo apt install dns2tcp

適当なサブドメインをNSで設定しておく

dns2tcp IN NS example.com.

server側の設定

$ cat ~/.dns2tcpdrc 
listen = <HOSTIPADDRESS>
port = 53
user=dns2tcp
chroot = /var/tmp/dns2tcp/
pid_file = /var/run/dns2tcp.pid
domain = dns2tcp.example.com
key = oopsoops
resources = ssh:127.0.0.1:22

で，とりあえずこんな感じで起動．

$ sudo dns2tcpd -F -f ~/.dns2tcpdrc

client側設定

$ cat ~/.dns2tcprc 
domain = dns2tcp.example.com
resource = ssh
local_port = 8022
key = oopsoops
debug_level=3

で，clientを起動する

$ dns2tcpc

これでserver側の22とclientの8022が繋がってssh出来るようになる

$ ssh user@localhost 8022

これでWeb閲覧をしたい場合は，-D でDynamic port fowarding するなどする．

$ ssh user@localhost 8022 -D 8080

socks5で 127.0.0.1:8080 な感じでいいはず

Description: Program launcher for idle X sessions
 Xautolock monitors input devices under the X Window System, and launches a
 program of your choice if there is no activity after a user-configurable
 period of time.  You can use this to automatically start up a screen locker
 if you have left your computer unattended for some period of time.  The
 program launched need not be a screen locker such as xlock.
