Well, three system reinstalls later, I think I have learned my lesson here. I don’t know how this thing does what it does but I’m done with it. I think the network settings are OK, but so many other issues, from no sound, PreferencePanes that wouldn’t open, and all kinds of Dock weirdness, makes me think I should have left it alone. Just ‘cuz it worked for Marc “I never have to work another day” Andreesen doesn’t mean it will work on my antiquated hardware.
Previously:
This little app came recommended by none other than Marc Andreesen (remember him?). The network settings looked like a fun place to start.
net.inet.udp.maxdgram: 9216 -> 65536
net.local.stream.sendspace: 8192 -> 256960
net.inet.tcp.sendspace: 32768 -> 224360
net.inet.tcp.mssdflt: 512 -> 2920
kern.ipc.maxsockbuf: 262144 -> 1048576
net.inet.udp.recvspace: 42080 -> 265152
net.local.stream.recvspace: 8192 -> 224360
net.inet.tcp.recvspace: 32768 -> 256960
kern.ipc.somaxconn: 128 -> 1024
net.inet.tcp.rfc1644: 0 -> 1
net.inet.tcp.newreno: 0 -> 1
If you feel like doing these by hand, you can use sysctl with those arguments:
sysctl -w net.inet.tcp.newreno=1
No idea if it will help, but why not?
Here are the sysctl settings if you want ’em.
sysctl -w net.inet.udp.maxdgram=65536
sysctl -w net.local.stream.sendspace=256960
sysctl -w net.inet.tcp.sendspace=224360
sysctl -w net.inet.tcp.mssdflt=2920
sysctl -w kern.ipc.maxsockbuf=1048576
sysctl -w net.inet.udp.recvspace=265152
sysctl -w net.local.stream.recvspace=224360
sysctl -w net.inet.tcp.recvspace=256960
sysctl -w kern.ipc.somaxconn=1024
sysctl -w net.inet.tcp.rfc1644=1
sysctl -w net.inet.tcp.newreno=1
Or you can use sysctl.conf to make them persistent:
white:~ paul$ cat /etc/sysctl.conf
net.inet.udp.maxdgram=65536
net.local.stream.sendspace=256960
net.inet.tcp.sendspace=224360
net.inet.tcp.mssdflt=2920
kern.ipc.maxsockbuf=1048576
net.inet.udp.recvspace=265152
net.local.stream.recvspace=224360
net.inet.tcp.recvspace=256960
kern.ipc.somaxconn=1024
net.inet.tcp.rfc1644=1
net.inet.tcp.newreno=1
