[Freeswitch-users] freeswitch in vmware

Fri Mar 7 11:21:22 EST 2008

Hello,
I have put my vmware guest machine in NAT mode.
This means there is a sort of private network between my host winxp PC
and guest PC running freeswitch.
I have reverted to default switch_private.h and run make current again.
Connnectivity seems ok to me, I have even runned a portscan from my host
pc
Starting Nmap 4.50 ( http://insecure.org )
d Time
Interesting ports on 192.168.60.129:
Not shown: 1708 closed ports
PORT     STATE SERVICE
22/tcp   open  ssh
113/tcp  open  auth
5060/tcp open  sip
MAC Address: 00:0C:29:1D:BB:69 (VMware)

However now I can't register as 1001 user to freeswitch, I get 403
forbidden!
I'm trying to register from the host PC to the guest PC, what's wrong
with this?

I send this:
REGISTER sip:192.168.60.129;transport=UDP SIP/2.0

Besides I don't remember having ever changed freeswitch configuration,
but maybe I have something broken since at the end of startup it seems
it opens sound files...

is this normal or not? If not can I do a make uninstall to remove fs
from my machine?

Thanks a lot,
Claudio

	It was confirmed by 2 people that using it in bridged mode is
the problem.
	Can you change vmware networking to NAT mode and tell me if it
works for you?

	I have done as you suggested to fix the clock (ntpd plus
clock=pit) and
	it seems to work.
	The problem of choppiness remain, I'm not sure if bridge network
is the
	problem because I've tried to connect from other machine to the
guest
	running freeswitch and the problem is the same.

	Thanks to everyone for suggestions so far!
