#man ipsec
Additional Variables
A number of sysctl(8) variables are relevant to ipsec. These are
generally net.inet.ah.*, net.inet.esp.*, net.inet.ip.forwarding,
net.inet6.ip6.forwarding, and net.inet.ip.ipsec-*. Full explanations can
be found in sysctl(2), and variables can be set using the sysctl(8)
#man npppd
Normally npppd works with pipex(4) to accelerate IP packet forwarding,

SIM Card Management Through GSM Modem On Linux

SIM Card Management Over GSM Modem

A small guide on how to send and receive USSD codes on Linux

I am using the built in GSM (UMTS) modem of my Thinkpad X1 extensively because I am often in places with flaky internet connections. I connect through the standard Network Manager on Ubuntu and everything works fine. There was one major annoyance though. Every time I wanted to top up the SIM balance or book a new package, I needed a phone to send and receive USSD codes. So I took some time to figure out how to do it from the shell. I wrote this down as a help for others and a reminder for myself. Without further ado...

First intsall gammu and picocom.

➜  ~  sudo apt-get install -y gammu picocom

Basic

  • Don't try "unprivileged" build from start.
    • First do cross-dirs/cross-tools/cross-distrib as root (sudo).
    • Then change owner/mode of obj directories. This will make development easier.
  • Always use cross build (for development).
    • Otherwise you'll overwrite your /usr/include during build.
    • Cross build can't make release on OpenBSD, unfortunately (because of gnu/, where Makefile.bsd-wrapper is used). So cross build is only for development.
