There is a variable named unix_nr_socks, > but AFAIK, the patch which used it (for /proc/net/protocols ) was > reverted lately. Pick your own definition of what is "the number of unix sockets". "lsof -U | wc -l " cannot be right because of shared file descriptors (one socket shared by several processes) "netstat --unix" seems to not display some sockets (which names dont start by / or @ , like in "private/smtp") If you use "netstat --unix --all", then all sockets are displayed. > > commit 1748376b6626acf59c24e9592ac67b3fe2a0e026 > by Eric Dumazet <dada1@...mosbay.com> You didnt understand this patch.
