Hi, some info about the machine: vpn-gw2# uname -a FreeBSD vpn-gw2 4.4-STABLE FreeBSD 4.4-STABLE #2: Tue Oct 16 16:42:27 CEST 2001 root@vpn-gw2:/usr/obj/usr/src/sys/VPN-GW2 i386 vpn-gw2# The machine is a dual 700MHz PIII with 512MB ram and 3 3c905B nics. /etc/sysctl.conf looks like this: vpn-gw2# cat /etc/sysctl.conf kern.ipc.shm_use_phys=1 vfs.vmiodirenable=1 net.inet.tcp.sendspace=65535 net.inet.tcp.recvspace=65535 net.inet.tcp.always_keepalive=1 kern.ipc.somaxconn=1024 net.inet.ip.rtexpire=10 I'm trying to set up mpd as a replacement for poptop + ppp. But I run into a problem when I try to configure more than 100 bundles. When I configure 30 bundles, everything works nicely. When I configure 100 bundles, things seems to work nicely, but when I run ngctl, I get the following error when typing 'list' at the ngctl prompt: [lines for ng100 - ng24 removed] Name: ng23 Type: iface ID: 00000849 Num hooks: 1 Name: <unnamed> Type: socket ID: 00000848 Num hooks: 2 Name: <unnamed> Type: vjc ID: 00000847 Num hooks: 4 Name: <unnamed> Type: bpf ID: 00000846 Num hooks: 3 Name: mpd37379-pptp12 Type: ppp ID: 00000845 Num hooks: 6 Name: ng22 Type: iface ID: 00000844 Num hooks: 1 Name: <unnamed> Type: socket ID: 00000843 Num hooks: 2 Name: <unnamed> Type: vjc ID: 00000842 Num hooks: 4 Name: <unnamed> Type: bpf ID: 00000841 Num hooks: 3 Name: xl0 Type: ether ID: 00000001 Num hooks: 0 ngctl: send msg: No such file or directory + quit it seems to be missing ng0 - ng21, but ifconfig shows all the interfaces. Earlier ngctl would not list any interfaces but print something like the following: + list ngctl: send msg: No buffer space available + quit which buffer is this, and how do I make it larger? On a PIII 1.3GHz with 1GB ram, trying to run with 110 bundles: vpn-gw3# uname -a FreeBSD vpn-gw3 4.4-STABLE FreeBSD 4.4-STABLE #0: Thu Oct 18 18:37:21 CEST 2001 root@vpn-gw3:/usr/obj/usr/src/sys/VPN-GW3 i386 vpn-gw3# [cut out 97 bundle configs] [pptp98] ppp node is "mpd18285-pptp98" [pptp98] using interface ng108 Radius: radius_Init [pptp99] ppp node is "mpd18285-pptp99" [pptp99] using interface ng109 Radius: radius_Init [pptp100] can't name ppp node: Address already in use [pptp100] netgraph initialization failed [pptp101] can't name ppp node: Address already in use [pptp101] netgraph initialization failed [pptp102] can't name ppp node: Address already in use [pptp102] netgraph initialization failed [pptp103] can't name ppp node: Address already in use [pptp103] netgraph initialization failed [pptp104] can't name ppp node: Address already in use [pptp104] netgraph initialization failed [pptp105] can't name ppp node: Address already in use [pptp105] netgraph initialization failed [pptp106] can't name ppp node: Address already in use [pptp106] netgraph initialization failed [pptp107] can't name ppp node: Address already in use [pptp107] netgraph initialization failed [pptp108] can't name ppp node: Address already in use [pptp108] netgraph initialization failed [pptp109] can't name ppp node: Address already in use [pptp109] netgraph initialization failed [pptp110] can't name ppp node: Address already in use [pptp110] netgraph initialization failed [pptp99:pptp99] vpn-gw3# ngctl + list ngctl: send msg: No buffer space available + This is with standard sendspace/recvspace.
