The sscop tool implements the Q.2110= transport protocol, [...] Q.2110 is ATM over ISDN B-channels, and the only use-case I have ever heard about is to run SS7 signalling over ISDN-30 connections. (The ability to do so is largely why phone scammers can fake the calling number when they annoy you.) Unless somebody else know of other uses, you can kill it. -- = Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe = Never attribute to malice what can adequately be explained by incompetence= .
