Hello list.
I have experienced a very unusual glich, that I cannot explain. All of
a sudden, my network router box became non-complient with internet
traffic requests. At first, I thought that it was because I had to
restart bind 8 with ndc resart, however, after restarting the service, I
still continued to recieve failed server errors. After attempting to
ping my provider, I noticed that I came accross this message:ping:
sendto: No buffer space available
ping: sendto: No buffer space available
ping: sendto: No buffer space available
ping: sendto: No buffer space available
What does this indicate? I am still learning, and do not have
significant experience/knowledge with any type of frame buffers, or
kernel programming. I can only suspect that maybe my firewalling rules
clogged some sort of buffers for the kernel. I don't really know, that
is the only thing that I can think of. I have the following firewalling
rules setup:
