Using tcpdump to sniff telnet password
Hi all,
As long as I can remember reading various articles/docs, they all say that
telnet is not secure because all traffic is in clear text. Well, out of
boredom, I try to sniff username and password from a telnet session.
The command I use: tcpdump tcp port 23 -vvv -w test.txt
Then I read the result: strings test.txt

unwanted locution
Hi, we are experiencing a problem that is very strange, only on SOME calls,
a locution jumps in to the RTP stream and both persons between the phones
can hear it. It is looped and it does not stop till hang up. Do you have any
clue about what could be happening ?
Thank you !

On what versions of FreeBSD can we unreserve ports?
On which versions of FreeBSD is it now possible to
un-reserve ports?
( I've been waiting for this since forever ... have
spent countless days - $$$ - trying to install
workarounds, only to junk them later. I've even
been paid a consulting gig to develop this, and
declined to deploy it on my own servers :-/ )

6.3-RELEASE-p3 recurring panics on multiple SM PDSMi+
We have 10 SuperMicro PDSMi+ 5015M-MTs that are panic'ing every few
days. This started shortly after upgrade from 6.2-RELEASE to
6.3-RELEASE with freebsd-update.
Other than switching to a debugging kernel, a little sysctl tuning,
and patching with freebsd-update, they are stock. The debugging
kernel was built from source that is also being patched with

OT: Capture Asterisk traffic
I want to capture all my Asterisk traffic (including RTP) and then analyse
it.
My plan was to use tcpdump and then analyse with Wireshark. The following
works:
tcpdump -i eth0 -s 0 -w /tmp/tcpdump.1
But I want to be a bit more selective:
tcpdump -C 100 -W 10 -w /tmp/tcpdump -i eth1 -s 0 udp and dst port >= 5060
This doesn't capture the RTP traffic. Could anyone advise what I'm

strange limitation on rcmd()
The manual page says, that rcmd() is only to be used by root's processes.
On other OSes (Solaris, AIX), trying to call rcmd() without being root simply
fails.
FreeBSD, however, tries to be helpful and invokes rcmdsh in this case, which
is inefficient and leaves the stderr's filedescriptor (fd2p) unfilled.
Why?
My understanding is, this is to make it harder for would-be attackers to

RTP session traversing Asterisk server ...
I've been reading up on the SIP and related (SDP/RTP) RFC's and as I would expect the RTP session should ideally be between the two end points of the call, in my case the AS5300 and the 7940 which are connected on the same VLAN as the Asterisk server.
When I sniff the packets on the VLAN I find that all RTP packets are being relayed by the Asterisk server causing increased load on the

stream rtp from asterisk
Hi!
Anybody familiar with streaming rtp from asterisk. Preferably with the
xorcom asterisk patch which streams rtp from asterisk to oreka audio

Weird 'hairpin' call rtp audio problem
Hello List
Asterisk 13.14.1 in use with pjsip stack.
On the remote side is a SBC which performs some 'nat' detection. I
suppose this means the SBC listens from where it is getting RTP data
and then replies to that ip.
As long as the asterisk is initiating the call this is fine, the
asterisk start sending RTP to the media IP of the SBC and the SBC is
sending media back.
Now I want to do

Gene,
As it happened I started working on this again just as you mailed me.
It appears that PXE-E99 may also be related to MTFTP part of the PXE spec. IBM also says it has something to do with jumbo frames. I tried setting PXE.mtcp-ip to 0.0.0.0 to disable it but still no joy.
The bootfile size shows up as zero because that relates to "option boot-size" in dhcp and doesn't seem to

Turn on SIP debugging from DialPlan
I have some troublesome numbers that I would like to capture the SIP
dialogue when I am calling them. When I am about to dial the number, is
there any way to turn on SIP debugging in the dial plan before I make the
call? (and turn it off after the call is completed?)

Segmenting wireless traffic
I''m considering adding a seperate subnet to my loc network making loc1
(192.168.1.0/24) and loc2 (192.168.0.1/24) with the goal of seperating
my wireless traffic from my wired LAN traffic.
Has anyone had success doing this, or is it still possible to sniff the
traffic of a seperate zone on the same interface with tools like ettercap?
