You can use this utility to verify connectivity of a host and determine how the host is connected to the Internet. You can also determine the path taken from UCSF to the specified host. This may help you, for example, to determine where packet loss may be occurring when you attempt to connect to hosts on the UCSF campus. It may also help you to determine whether routing difficulties, either in the Internet or within the UCSF campus network, may explain problems connecting to hosts on the UCSF campus.
This is an experimental server. If you have any questions or comments about its functionality, feel free to send electronic mail to the address listed below and we will attempt to get back to you shortly.
