how to assign a real IP to a PPP host?

how to assign a real IP to a PPP host?

[Patrick van der Smagt]

Dear Netfilters,

I'm blocked by the following problem.  My host has two IPs on interface 0:
	12.12.12.12
	12.12.12.13
The first IP is its "real" IP on eth0:0, I created the second one to have
it assigned to a ppp-connected client machine.

To my host a second machine is connected over a ppp connection, and it
has the local IP 10.1.0.100.  What I want to do is to give the remote
machine the permanent IP 12.12.12.13.  I want all network traffic for
10.1.0.100=12.12.12.13 (and a cluster of machines behind that) to be
routed through 12.12.12.12.

I've set up iptables as follows to do what I want:
  iptables -t nat -D PREROUTING --dst 12.12.12.13 \
        -j DNAT --to-destination 10.1.0.100
  iptables -t nat -D POSTROUTING --dst 10.1.0.0/24 \
        -j DNAT --to-destination 12.12.12.13
  iptables -t nat -D OUTPUT --dst 12.12.12.13 \
        -j DNAT --to-destination 10.1.0.100
The first and second rule work fine, with those I can reach my machine
10.1.0.100 at address 12.12.12.13 from all hosts, except 12.12.12.12 (of
course). That's what the third rule is for.  However, rule 3 does not
do everything for me.  After setting up all of the above rules, when I
telnet to port 110 from .12 to .13, I receive no answer.  I find in
/proc/net/ip_conntrack on .12:

tcp      6 118 SYN_SENT src=12.12.12.13 dst=12.12.12.13 sport=2996
dport=110 [UNREPLIED] src=10.1.0.100 dst=12.12.12.13 sport=110
dport=2996 use=1

or

tcp      6 57 SYN_RECV src=12.12.12.13 dst=12.12.12.13 sport=2996
dport=110 src=10.1.0.100 dst=12.12.12.13 sport=110
dport=2996 use=1

How do I get this running??  Please help!

How will I mesure my bandwith

[Sundaram Ramasamy]

Hi,

We have 512kbps connection to our office, How will I measure my bandwidth.

I used following link, it show only 368.2kbps. Is there any other method to
test this.

Thanks
Sundaram

You could use a tool such as iptraf http://cebu.mozcom.com/riker/iptraf or 
simply check the byte counts for your external interface at regular intervals.

ifconfig eth0 | grep bytes
will tell you the number of bytes in & out of eth0 - you could set a cron job 
to do this every minute and redirect the results to a file ?

This is very unlikely to be a firewall problem.

What do the headers of the emails say ?   Where is the excessive delay 
occurring ?

If you are interested in more detailed information, my ulog-acctd
(http://savannah.nongnu.org/projects/ulog-acctd) may be the solution
for you.

You can also use a tool like MRTG that looks at the interface byte
counters on a regular basis and puts out nice graphs based on those
numbers. But AFAIK you also need a working SNMP daemon setup for that.

Google for bing displays lots of stuff about Mr Crosby, plus some links to 
getting the source from ftp://ftp.ibp.fr which doesn't seem to exist...

Looks like an intriguing way to measure bandwidth - I'd be interested to test 
it and see how reliable the results are - can you suggest where I can get it 
from ?

[Heupink, Mourik Jan C.]

just add download to the search 
(http://www.google.com/search?q=bing+bandwidth+download&sourceid=opera&num=0
&ie=utf-8&oe=utf-8)
and the fist hit IS valid :)

can't get it to compile, though....

Hi,
Please try darkstat. it is pretty cool one and easy to install. It runs
on port 666 by default and you can access it with,
http://1.2.3.4:666
where 1.2.3.4 is your ip.
Thanks and bye.

Debian has a pacakge for it, (apt-get install bing), so if you can 
install DEBs you can get it from 
http://packages.debian.org/stable/net/bing.html

Reading the README that came with, you can get new releases at 
http://www.freenix.org/reseau/outils.html

The site might be in French mind you.
