Harald Welte laforge at gnumonks.orgHi Arturo,
please make sure your subject is correct. Your message is not about
OpenBTS, but about OpenGGSN.
Secondly, OpenGGSN has its own mailing list, which is the better place
to ask your question:

This is also very clear: It tries to create the file
/var/lib/ggsn/gsn_restart, but apparently the directory /var/lib/ggsn
does not exist!

Even more clear: the GTP protocol has already bound to, i.e. you have
some other process running that has already claimed the GTP protocol on
your specified IP address.
GTP is a layer4 protocol, not layer5 like http/ftp. You cannot have
multiple prgrams using GTP on the same IP address. Only one GTP socket
can be opened for each address. In case of doubt, run GGSN and SGSN on
separate machines.
