Custom CLI (spoofing) ?
I'm trying to have a go at CLI spoofing. My outbound calls may go out over various VoIP providers, using least cost routing to determine which provider for call destination and time of day. No matter which provider I go out over, i'd like the called party to only see only one of my numbers - that number will be the only number...

masquerading
Following Situation: Having an intranet-application that needs to know the ip-Address of the clients before running. Clients anywere in the Internet with any ip-address. So I thought about using masquerading the opposite way than normal. But then anybody could use this application. Dos anybody know how to make it a little bit more secure, like proofing the mac-address of the client, or something

C7 and spoofed MAC address
Got a problem: a user's workstation froze. He wound up rebooting, without calling me in first, so I dunno. But, and this is a show-stopper, when it came up, it came up with the firmware MAC, not the spoofed one. In /etc/sysconfig/network-scripts/ifcg-eth0, I've got the spoofed MAC address, and a UUID. In the grub.conf, I've got net.ifnames=0 biosdevname=0. But when I logged onto his machine, ip a showed eth0... but with the firmware MAC. And I'm wondering if it went to renew its IP addr...

Spoofing a BLF Signal?
Is there anyway to "spoof" a BLF signal to a phone from within a dialplan? That being so I can turn a BLF light on or off on a phone when a certain thing happens in a dialplan?

What are some programs to use to trace spoofers?
...of gaining entry. This guy was good at hiding his/her tracks so we reinstalled the OS and left a minimum install to see if it was done again. We logged all goings on from a secure remote machine. We got the hacker''s IP address and even some of what he/she did on the box. But the IP was spoofed. I heard there was a way to trace a spoofed IP ( I know tracing can''t be done after the fact). Any ideas? And what are some good programs out there to do so? There is a chance that the hacker attempted a connection to see if the box was still up before he/she spoofed the IP. I have...

security: SIP header spoofing CHANNEL(recvip)?
I am currently suffering various SIP attacks. I am using the following extension to record the caller's IP address: exten => h,n,set(CDR(srcip)=${CHANNEL(recvip)}) However, in recent attacks, this IP address is not correct, and I believe that they are spoofing it. I am using asterisk 1.6.2.15. Does the CHANNEL(recvip) variable record IP show in the SIP header instead of the real, UDP source IP? If the CHANNEL(recvip) variable records the IP address set in the SIP header, and not the real IP address, how can I obtain the REAL IP address of the caller?

Caller ID spoofing
...playing with asterisk, i can't solve it: I am trying to integrate my existing H.323 network in real world telephony by ISDN cards. The problem is that i DON'T want to change all e164 numbers in my h.323 network and my ISDN provider doesn't accept those identities (CIDs). So, i have to spoof the outgoing CID depending on incoming CID. Is there any possible way of doing this by AGI? How? any examples are welcome. Also, if i don't ask too much, it would be great to integrate this "CID translation" table in my existing MySQL database for Asterisk. Thanks, Calin Serbanes...

mac spoofing
Hi, I have the following Problem: My Rootserver stands at a hoster, I run a debian sarge and installed Xen 3 there latetly. I booted the xen Kernel - everything ok. However: when I started xend, the server instantly stopped responding. My Hosters Support said, that was due to a sort of mac spoofing protection in the switch, which disabled the Port, to which my server is connected, because there arrived an unknown Mac Address from my Server at the switchport. ( btw: at that point, I had not configured any domU''s ) >From the Xen Docs I understand that the bridge gets the mac f...

vif-common.sh and iptables
Hey everyone, I have a question about vif-common.sh. I run multiple bridges attached on dummy interfaces, which allow me to put guests in seperate subnets (routed through the dom0). As you might expect I already have quite extensive iptables scripts to accomidate this kind of routing. I was just hoping someone on this list can confirm, that I understand what the iptables lines in vif-common.sh
