I was wondering if anyone out there knows if you can create a raw socket that talks directly to the ethernet interface. The project group I'm in is trying to bypass the IP layer on a Sun-2, but we don't want to hack the kernel (not to mention that our system administrator wouldn't be too happy about that). The manual says that with the proper privileges, one can talk directly to the IP layer, but we haven't been able to get any info on whether sockets allow you to go directly to the ethernet layer. Thanks in advance for any help you folks can offer, David Yang yang@b.cs.uiuc.edu

Use AF_DLI, the Data Link Interface layer. Of course, it is not implemented. (Oh well.) >The project group I'm in is trying to bypass the IP layer on a Sun-2, >but we don't want to hack the kernel.... If you are running SunOS 3.2 or later, look up `NIT' (Network Interface Tap) in the manuals. NIT exists in 3.0 but is largely broken there. -- In-Real-Life: Chris Torek, Univ of MD Computer Science, +1 301 454 7163 (hiding out on trantor.umd.edu until mimsy is reassembled in its new home) Domain: chris@mimsy.umd.edu Path: not easily reachable
