NAME

	tinc – mesh peer to peer VPN

SYNOPSIS

	ip/tinc [ –d ] [ –p maxprocs ] [ –x inside ] [ –o outside ] [ –c confdir ] [ –n myname ] localip localmask [ hosts... ]

DESCRIPTION

Tinc implements the mesh peer to peer VPN protocol from https://www.tinc–vpn.org/ as of version 1.0.36. Within a tinc VPN one can reach all the subnets of all hosts within the network even when not directly connected to the owning host of the subnet. Each host that is directly connected to us has its own hostfile under confdir/hosts/hostname containing its public address, owned subnets, options and RSA public key. The hostfile format is the same as the original tinc implementation. The confdir is specified with the –c option or defaults to the current working directory. Other hosts might exist behind these directly connected nodes but this information is distributed automatically within the protocol. On startup, tinc creates an ip interface with the address localip and network mask localmask on the inside ip stack (specified with –x option) and starts listening for incoming connections on the outside ip stack (specified with the –o option). When optional hosts are specified on the command line, then it will also do outgoing connections using the outside ip stack. The localmask usually is a supernet of all the subnets within the VPN. Our own hostname myhost can be specified with –n option or is assumed to be the sysname when not specified. This host's RSA private key needs to be present in factotum and tagged with service=tinc and host=myhost. The options: –d    Enable debug output and do not fork to the background. –p    Limit the number of client processes (incoming and outgoing connections per protocol) to maxprocs. –x    Specifies the inside and outside network stack directory where the tinc ip interface is bound. Defaults to /net. –o    Specifies the outside network stack directory where incoming and outgoing tinc connections are made. Defaults to inside. –c    Specifies the configuration directory confdir for the VPN. –n    Sets our hostname to myname.
