While I appreciate the suggestion, the procedure given on that link
involves patching one's kernel! Which makes the already-lengthy
procedure recommended by

that much longer, and (IMHO) even more risky and less maintainable.
Instead I recommend the following doc fixes:

1 The "Getting Started on Topsail" doc

must state that one will be unable to ssh into topsail from off-campus
without a VPN. In fact, the instructions for use of *any* campus
facility that only works inside the firewall should so indicate,
presuming one wants to avoid wasting users' time.

2 The top-level VPN information pages, e.g. "Frequently Asked
Questions About VPN"

must indicate that the Cisco VPN client that UNC ITS currently
supplies via will not build against newer
2.6-based kernels.

3 The lower-level pages on VPNing from linux, e.g. "Installing the VPN
on Linux"

should be improved to point to much simpler options than installing
the heavy Cisco client, e.g.

* the SSL VPN

* for newer linuxes (e.g. ubuntu >= 9.04), the vpnc plugin for the
GNOME Network Manager. For UNC-specific instructions, see

which are adapted from the very-nicely-done instructions @

TIA, Tom Roche [Tom_Roche AT]
