Got Burned Hacking
Hacked TCP/IP RWIN sucessfully from APR 02 article. Was playing around to fine tune it, thought i changed recvspace and screwed it. Now won't boot . how do you 'see' private files like /etc/rc on active system. I was going to replace hacked file with virgin file, thus eliminating rebuilding everything, can't see it to copy it off new system folder.

Re: Got Burned Hacking
Yes, you should be to see and do everything via the Terminal, though you'll need to use an admin account and the "sudo" command, since the files involved are not public writable. If you "cd /Volumes" that'll take you to the top-level directory, from which you should be able to navigate to other partitions, etc.
HTH - Good luck!

Re: Got Burned Hacking
For what its worth, you don't need to hack the /etc/rc file to adjust your TCP recv window size (or any other sysctl variable, for that matter).
Create the file /etc/sysctl.conf (if it doesn't exist already), and drop your settings in there. The format of the file is as follows:
variable1=value1
variable2=value2
...
In your case, the file would appear as:
Code:
net.inet.tcp.sendspace=131072 net.inet.tcp.recvspace=358400
(put your own values in there)

Re: Got Burned Hacking
You've messed around with an OS and had to re-install?
Join the club. How many times have I done that? Maybe ten times or so, with various operating systems.

Re: Got Burned Hacking
Ya - and since upgraded to 10.3.9 from 10.3.5, software restore on original doesn't like me.
Of course that hasn't prevented me from hacking ala terminal - but i'm much better at starting the whole shebang over again.
