Re: "No buffer space available" when scanning a Class A or B net

Sounds feesable. But this would be my first time messing around with any settings in /proc/sys/net. Are there any guides out there I can use to educate myself before I go "willy-nilly" in there?

Thanks for the reply Curtis

The problem is, if I try to scan any more than a Class C, I get a "No buffer space available" error and the scan get's bogged down with 15 and 60 second pauses between scans.

You could try fiddling with /proc/sys/net/core/wmem_max or /proc/sys/net/ipv4/tcp_wmem to see if those buffers are the culprits.
