...These may be separate issues, but I thought I would also mention the "kernel: Neighbour table overflow." error I get quite frequently. The research I have done suggests that the lo interface is not enabled.

Hi, I am currently using the L2 tunnel feature of ssh between two Linux machines, and it works beautifully! As a result, I have come to prefer a workflow that uses an L2 tunnel, but I can't seem to find a long-term solution for this workflow on macOS. At the moment, tap devices on macOS can be generated using a kernel extension like tuntaposx <http://tuntaposx.sourceforge.net/>;

Hello all, I need a virtual firewall/router solution. I''m thinking of a netscreen 1000 but I want to know if it can be done in Linux. Here is my idea: 1 Linux box 2 GigE interfaces 1 interface setup with a public IP address ($PUBIP) 1 interface setup with 802.1q VLAN trunking with 100 vlans assigned ($VLAN1-$VLAN100) a /25 subnet routed to $PUBIP from my core routers All $VLAN

...ignore the arp request for alias ip ,at the same time I don't want disable the arp function of the interface ? How do ? thanks! Probably you need to assign this ip on loopback interface. This address will no more used for arp, but still can be accessible if there is route (IPv4 gw based or LLaddr gw based) for other hosts on ethernet. But, there is some drawbacks also - source IP address autoselect will not chose this IP when you connection to other host. -- Vladimir B. Grebenschikov vova@fbsd.ru

My intention is to set up tinc so that I can connect from home to an office network. All CPUs are running MacOs X, 10.2.8 or 10.3.5. I have read the tinc manual, tincd.8 and tinc.conf.5. However, I am still unclear about a few issues. First and foremost, how to I setup the VPN interfaces on the hosts, on MacOs X? Which file do I have to alter and what is the exact syntax on Os X to setup
