Have posted in networking, but again here due to higher traffic.
I am logging on to my college's VPN and using my mail account there. However, I get serious bandwidth issues - its explained in one of the faq's but I'm a bit unsure about the work around as I don't know much about terminal. Also I'm getting Panther soon, so would prefer not to eff everything up!
Here's the script:
Problem:
When using Netscape within the VPN, it is not possible to see websites outside the College.
Solution:
The MTU size controls the maximum size each packet of data sent can be. The VPN service adds extra data into each packet, which increases the total size of each packet. If the packets exceed the size specified by the MTU setting, then they are truncated, meaning you cannot successfully surf the web. The solution (for now) is to reduce the size of the MTU used by Mac OS X.
Here is the suggested solution from our network group:
1) Log in using your administrator account. Open a terminal window (in the Finder it's Go -> Applications, then open the Utilities folder and double click the Terminal icon)
2)Type in "cd /etc"
3)Type in "sudo mkdir ppp", and enter your administrator password when asked.
4)Type "sudo pico /etc/ppp/ip-up"
5) type in the following:
#!/bin/sh
/sbin/ifconfig ppp0 mtu 1365
/sbin/ifconfig ppp1 mtu 1365
(Note: 1365 only represents the new MTU you want to use - to be no higher then 1492)
6) Close the text editor 'Pico' using "control" and "x", save the file when asked (simply press "enter")
7) Type "sudo chmod 755 /etc/ppp/ip-up"
8) Reboot your Macintosh and Surf Away!
