Source Configuration

GIT

Commands

  • Get your copy
git clone ssh://sevenbone@penguins.dreamhost.com/~/git/7bone.git 7bone
  • Make some modification and compare
git diff
  • Update your local copy with the master repository changes
git pull
  • Add some files to your GIT repository
git add File14 
git add Dir32
  • Commit these changes and new files to your local GIT repository
git commit -m "Comment message here"
  • Push your changes to the master repository
git push origin master

Installation

OpenSS7

On Ubuntu 8.04 (only this version, highly kernel version dependent) 

apt-get install groff-base info bison flex
apt-get install linux-libc-dev libc6-dev libperl-dev
./configure --without-snmp
make
make install

M3UA

  • Check /home/user/openss7-0.9.2.G/sigtran-0.9.2.4/src/modules/m3ua_as.c

SCTPlib

kextload /System/Library/Extensions/SCTP.kext
  • In order to compile the examples programs (echo_tool etc...) with SCTPlib:
gcc -DHAVE_CONFIG_H -I. -I../.. -I./../sctp  -I/opt/local/include/glib-2.0 \ 
 -I/opt/local/lib/glib-2.0/include -I/opt/local/include    -g -O2 \
 -I/opt/local/include/glib-2.0 -I/opt/local/lib/glib-2.0/include \ 
 -I/opt/local/include   -DDARWIN -DUSE_SELECT -Wall -g3 -O0 -D_REENTRANT \
 -D_THREAD_SAFE  -o echo_server echo_server.c sctp_wrapper.c  -lsctplib

gcc -DHAVE_CONFIG_H -I. -I../.. -I./../sctp  -I/opt/local/include/glib-2.0 \
 -I/opt/local/lib/glib-2.0/include -I/opt/local/include    -g -O2 \
 -I/opt/local/include/glib-2.0 -I/opt/local/lib/glib-2.0/include \
 -I/opt/local/include   -DDARWIN -DUSE_SELECT -Wall -g3 -O0 -D_REENTRANT \
 -D_THREAD_SAFE  -o echo_tool echo_tool.c sctp_wrapper.c  -lsctplib
  • NKE and SCTPlib are mutually exclusive.

Intel / Dialogic SS7 stack

Configuration differences between two peers

  • Useful bits
    • For logging
FORK_PROCESS    ./s7_log -fms7.log -o0xff1f -pms7.pcap
  • Between two different configs

Configurations

Hamachi

Quick Start

Run 'make install' and then 'tuncfg' from under the root account
Run 'hamachi-init -c /etc/hamachi' to generate crypto identity (any account).
Run 'hamachi start' to launch Hamachi daemon.
Run 'hamachi login' to put the daemon online and to create an account.
Run 'hamachi join <network>' to join the network.
Run 'hamachi go-online <network>' to go online in the network.
Run 'hamachi list' to list network members and their status.


OpenVPN

Introduction

Good tutorials can be found here:

we will use tcp port 9443 for openvpn VPNSSL configuration. So your firewall should allow this port out.

OpenVPN Certificates

coming

OpenVPN Client configs

client
dev tun
proto tcp
remote lab.tstf.net 1337
resolv-retry infinite
nobind
persist-key
persist-tun
comp-lzo
ns-cert-type server
user nobody
group nogroup
ca ca.crt
cert client.crt
key client.key

OpenVPN Server configs

local [EXTERNALIP] port 8443 proto tcp dev tap0

  1. we'll add section how to manage certs later

ca /etc/openvpn/easy-rsa/keys/ca.crt cert /etc/openvpn/easy-rsa/keys/server.crt key /etc/openvpn/easy-rsa/keys/server.key dh /etc/openvpn/easy-rsa/keys/dh2048.pem

  1. this will allow for people to get the same IP address after a reconnect

ifconfig-pool-persist /etc/openvpn/ipp.txt

keepalive 10 120 comp-lzo max-clients 10 user nobody group nobody persist-key persist-tun status /tmp/openvpn-status.log log-append /var/log/openvpn.log verb 6

Networking

/etc/init.d/net-addroute restart) 

       echo "No reload possibility for this script"
       ;;
  • )
       echo "Usage: /etc/init.d/net-addroute {start

Cisco ITP

  1. cs7 variant itu
  2. cs7 point-code 1.2.3
  3. Maybe: cs7 capability-pc 1.2.3

Diagnostics

SIGTRAN sniffing

  • wireshark
  • Remove the HEARTBEAT and HEARTBEAT_ACKs with display filter:
sctp.chunk_type != 4 and sctp.chunk_type != 5
  • Check inits
sctp.chunk_type == 1

Testing

Security
