Hi,
Yes, I was successful actually :)
The configuraton was as follows(ip addresses changed to hide the box--
s/real.ip.address/192.168.1/g):
Co-located machine had 2 IP addresses assigned:
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 192.168.1.11 netmask 0xffffffc0 broadcast 192.168.1.63
inet 192.168.1.14 netmask 0xffffffff broadcast 192.168.1.14
ether 00:02:b3:d1:c5:39
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
Machine at office had two bridge mode 1.5Mbit/256kbit ADSL connections(The IP
addresses were just ifconfig'd on each NIC).
The co-lo machine's ppp.conf is as follows:
#---start ppp.conf---
default:
#Only enable logging for troubleshooting
#set log CBCP CCP Chat Connect Command IPCP tun Phase Warning Debug LCP sync
#set log Connect tun Phase Debug LCP
set log Connect tun Phase LCP
#set log Chat Connect Command IPCP tun Phase Warning LCP
ppp-in:
set timeout 0
set speed 0
set device 192.168.1.11:7900/tcp 192.168.1.14:7900/tcp
set enddisc MAC
set mrru 1450
set mtu 1450
set mru 1450
set dial
set login
# Addresses for: MyAddr, HisAddr, Netmask
# set ifaddr 192.168.2.1/8 192.168.3.1/8 255.255.255.255
# set ifaddr 192.168.2.1 192.168.3.1/24 255.255.255.255
set ifaddr 10.60.50.5 10.60.50.6 255.255.255.252
#Chap is encrypted, pap isnt
enable chap
disable pap
enable MSCHAPv2
enable lqr
#---End ppp.conf---
The co-lo machine's ppp.secret contains:
#---start ppp.secret---
username_goes_here password_goes_here 10.60.50.6
#---end ppp.secret---
/etc/inetd.conf on the co-lo machine had the following lines added:
#--start--
#incoming ppp
ppp-in stream tcp nowait root /usr/sbin/ppp ppp -direct ppp-in
#--end--
/etc/services had the following added:
#--start--
ppp-in 7900/tcp #incoming TCP ppp session
#--end--
The Office Machine's ppp.conf is as follows:
#---start ppp.conf---
default:
#set log CBCP CCP Chat Connect Command IPCP tun Phase Warning Debug LCP sync
set log Connect tun Phase LCP
multilink:
set escape 0xff
# set device 192.168.1.11:7900/tcp 192.168.1.14:7900/tcp
set speed sync
set ctsrts off
set timeout 30
set authname username_goes_here
set authkey password_goes_here
# enable lqr
set mrru 1450
set mtu 1450
set mru 1450
clone 1,2
link 1 set device 192.168.1.11:7900/tcp
link 2 set device 192.168.1.14:7900/tcp
link deflink remove
link 1,2 set mode ddial
#---end ppp.conf---
ppp on the office machine was started with:
ppp -background multilink
The co-lo machine's uname -v:
FreeBSD 4.8-STABLE #1: Sat Jul 12 22:10:42 WST 2003
sdwyer@server.<obscured>.com.au:/usr/obj/usr/src/sys/SERVER
The office machine's uname -v:
FreeBSD 4.8-STABLE #0: Sat Jul 5 17:35:42 WST 2003
root@server.<obscured>.org.au:/usr/obj/usr/src/sys/SERVER
Performance increase was about what I expected.. doing an FTP download
we were seeing about 280kb/sec. Uploads were going at about 38kb/sec
Not too bad considering it was a quick and dirty job. I tried to get it going
with UDP but it refused to
work for some reason. Perhaps MTU/MRU stuff could be tuned a bit more finely but
in the end
it wasnt going to be quite fast enough for the client. He was hoping to see
45kb/sec for uploads.
Let me know how you go :)
ive cc'd this to net@freebsd.org in the hope that it becomes useful to some one
else also.
Mabye something a bit too obscure for the FAQ or Handbook.. let me know if im
wrong :)
Cheers,
-Shaun
