Added -L../gtp to sgsnemu and ggsn makefiles so that make will
work without an installed libgtp.
Added sgsnemu check to check for valid pointer when deleting tun.
Removed enabling of ip_forward = 1 from ggsn.c and sgsnemu. From a
security point of view it was not very good that openggsn
automatically enabled routing.
Added ipup, ipdown and createif to sgsnemu/cmdline.ggo. Now
sgsnemu will set up default route and then execute ipup script
after tun device has been set up. After tun has been deleted the
ipdown script is executed.
Added support for ping to sgsnemu.
Added ipup and ipdown to ggsn/cmdline.ggo.

You need to be root in order to install the package, but not in order
to compile.
Steps 2 to 5 are only needed the first time you install the
package. Most likely steps 8 and 9 can be omitted as the path to
libgtp is now included in Makefile.am for sgsnemu and ggsn.

*** Performance ***
Two experiments were performed in order to test the performance of
sgsnemu and ggsn. The ggsn used a 550 MHz Athlon with 384 MB of
RAM. sgsnemu used a 1 GHz Athlon with 256 MB of RAM. Both machines had
100 Mb/s NICs and were connected through a Netgear FS105 switch. Both
tests were performed by sending ICMP echo packets from the ggsn to
sgsnemu.

with a payload of 1000 bytes. Transfer time 0.9 sec, no packets lost.

If the above went well you might want to try to establish a PDP

establishing PDP contexts using sgsnemu as each established PDP
context will result in a Charge Detail Record (CDR) being generated by
the GGSN. You should use real IMSI and MSISDN from a valid test SIM
card. Otherwise some poor customer might get charged for your
testing. Also note that you are establishing a connection to the Gi
