We are using Poptop as PPTP and PPPoE server to Internet for our clients. C= urrently, there are about 3000 tunnels in sum at the moment. Seven server under FreeBSD (from 6.1-PRERELEASE to 7.0-CURRENT, i386 and amd64) used for poptop, ng_netflow for traffic accounting, dummynet for shaping and ipfw, of cause, for firewalling. Hardware are simple enough - Intel P4 3,0-3,2GHz; 2Gb RAM; Intel Gbit NIC on-board. So, some questions now: 1. How do correctly shape traffic - dummynet emulate propagation, not only rate-limit or, like Cisco, "clear" traffic shape. 2. Does anybody use mpd for hardly-loaded servers? 7.0-CURRENT, for example, died in kernel trap after creating node "ng1970". Poptop also, sometimes, invoke system kernel trap, especially with PPPoE configuration, but more often system deafly freeze until reset. =3D( I hope, it's not a just-another-silly-questions-about-RTFM ;-) --=20 =D1 =F3=E2=E0=E6=E5=ED=E8=E5=EC,=20 =DE=F1=F3=EF=EE=E2 =C4=E5=ED=E8=F1, =F1=E8=F1=F2=E5=EC=ED=FB=E9 =E0=E4=EC=E8=ED=E8=F1=F2=F0=E0=F2=EE=F0 Ozerki.= Net mailto:dyr@homelink.ru
