Howto proxy network connections in Emulator

Get tsocks

Since the emulator is running as x86, you can just copy over your tsocks files from your linux distro

• Fire up the emulator (palm-emulator)
• copy tsocks to Emulator -> /usr/local/bin

scp -P 5522 /usr/bin/tsocks root@localhost:/usr/local/bin

• copy libtsocks.so to Emulator -> /usr/lib

scp -P 5522 /usr/lib/libtsocks.so root@localhost:/usr/lib

Create the tsocks.conf file

# This is the configuration for libtsocks (transparent socks)
# Lines beginning with # and blank lines are ignored
#
# The basic idea is to specify:
#	- Local subnets - Networks that can be accessed directly without
#			  assistance from a socks server
#	- Paths - Paths are basically lists of networks and a socks server
#		  which can be used to reach these networks
#	- Default server - A socks server which should be used to access 
#			   networks for which no path is available
# Much more documentation than provided in these comments can be found in
# the man pages, tsocks(8) and tsocks.conf(8)

# Local networks
# For this example this machine can directly access 192.168.0.0/255.255.255.0 
# (192.168.0.*) and 10.0.0.0/255.0.0.0 (10.*)

local = 192.168.0.0/255.255.255.0
local = 10.0.0.0/255.0.0.0
#local = <Network for your personal network>/<netmask>


# Paths
# For this example this machine needs to access 150.0.0.0/255.255.0.0 as 
# well as port 80 on the network 150.1.0.0/255.255.0.0 through
# the socks 5 server at 10.1.7.25 (if this machines hostname was 
# "socks.hello.com" we could also specify that, unless --disable-hostnames
# was specified to ./configure).

##path {
#	reaches = 150.0.0.0/255.255.0.0
#	reaches = 150.1.0.0:80/255.255.0.0
#	server = 10.1.7.25
#	server_type = 5
#	default_user = delius
#	default_pass = hello
#}

# Default server
# For connections that aren't to the local subnets or to 150.0.0.0/255.255.0.0
# the server at 192.168.0.1 should be used (again, hostnames could be used
# too, see note above)

#server = 192.168.0.1
server = <IP OF YOUR socks proxy>
# Server type defaults to 4 so we need to specify it as 5 for this one
server_type = 5
# The port defaults to 1080 but I've stated it here for clarity 
server_port = 1080 

default_user = user@host
default_pass = <password here>

• You can test your config file by doing this

/usr/local/bin/tsocks wget http://www.cnn.com

• If you are behind the socks proxy and the tsocks.conf is setup correctly, then the wget command should work.

Shim LunaSysMgr

Permanently shim LunaSysMgr

• You can force LunaSysMgr to always use the proxy by editing the upstart script that lives in /etc/event.d
• Add the tsocks line in front of the call to exec LunaSysMgr
• vi /etc/event.d/LunaSysMgr and update the exec line to make it look like this:

exec /usr/local/bin/tsocks /usr/bin/LunaSysMgr -s `cat /var/luna/preferences/sysmgr-args`

• reboot the emulator. enjoy.
