GRE tunnels anyone?
The company I work for uses a lot of multicast tunnels, usually with a QOS/GRE implementation with quite pricy hardware. I googled around a bit, it looks like basic vpn is supported for FreeBSD. I guess my questions are 1.)Does FreeBSD play well with vpn-capable routers (like a 3Com 5012) 2.)Would getting acceptable latency tunneling multicast mean hardware that's just as expensive as a router costing thousands?

[mailer daemon - original message truncated] It appears you are right. I guess the Gates foundation does have a controlling interest in FreeBSD.

You need to set up an internal forward zone in your DNS to direct requests to the internal address .To see what I am talking about, trying pinging your website from the inside using the external address. If your router is set up appropriately, you should get a 'TTL expired' message. Set up an 'A' record for www in mywebsite.com on one of your internal boxes to point to 192.168.0.2, and set up forwarders to your ISP's name servers on this box. Set all your internal hosts to use that machine for DNS requests, and you will be good to go. -Joshua Weaver ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

google up arp-sk, use it to modify the arp tables in switch and play with him a bit :) -Joshua -Original Message- From: [EMAIL PROTECTED] [mailto:owner-freebsd- [EMAIL PROTECTED] On Behalf Of Mike Hernandez Sent: Wednesday, September 07, 2005 10:26 AM To: [EMAIL PROTECTED] Subject: Re: port scanning and hidden servers If you ask him not to do so, then you know who he is, correct? The best way to prevent him from continuing is to deny him access to the network. AFAIK there is no way to block a scan, though you could close ports and otherwise secure your systems so that the scans won't produce any helpful information? Hiding a server wont help much, nmap can scan blocks of IP's. If the servers aren't on the same network as your users they can't be scanned easily, but that might complicate your setup. IMHO, revoke the user's permission to access the network, or bring up the issue with someone who has the authority to do so.

Re: Will this actually work?
No, it uses layer 2 communication at that point. On the 6 FreeBSD stations I have, you are apparently right. It looks like a way to exploit a system without access to the ports. I'm not sure why the kernel intercepts the data that way (you didn't even use a NOP sled.) -Josh ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
RE: OT: Re: WinXP administration guide for unix guru
What are the symptoms that you need administrator privileges? The default security scheme, even with the SP2 behemoth installed, require an administrator or power user to install the printer, but a user can print to it. Is this just a postfix or pdl printer installed with a local tcp/ip port or are you connecting to a shared network printer off a samba machine?

It doesnt ** Reply Separator ** Monday, August 22, 2005 4:50:11 PM That is a simple fix. If this is a domain environment, open up the security properties of the printer and add Authenticated Users and give them the print privilege. This is similar to having to change permissions, etc. in order to allow non-root users the ability to mount floppy drives, etc. in FreeBSD. Thanks for the tip, but this isn't a domain environment. There is NO security property available for this printer. This is the only machine I'm tolerating a M$ OS on, so I don't really need the hassle of a domain. The printer in question has its own ethernet port, and runs its own printserver, and security is intended to be open to any system within my network.

RE: man malloc
Pointer coercion is standard terminology, it is used when you force cast a pointer as a different data type. Btw, most processors since the late 90's can handle a variable not aligned to their word length, so it would be uncommon. Good question, Sergey.

What does suitable aligned for storage of *any* type of object means? In what way is that difficult to understand? It can't really be expressed any simpler, and it means exactly what it says: That the storage allocated by malloc is suitably aligned for storing any kind of object. As an example, it is not uncommon for many systems to require that a 32-bit integer must be aligned on a 4-byte boundary. (I.e. if the CPU tries to access such an object placed on an address that is not a multiple of 4, then the program will crash.) Exactly what alignment is required for different objects can vary quite a bit, but malloc guarantees that the storage it allocates is aligned in such a way that you can store any kind object in it (assuming it is large enough, of course.) What is pointer coercion? No idea. It is not standard terminology anway. I have no pointer before malloc() returns. Then where do you store the value returned by malloc? You almost certainly do have some pointer even before malloc returns, but that pointer might not contain any useful value. -- Insert your favourite quote here.
