VIRT(4) 						   BSD Kernel Interfaces Manual 						   VIRT(4)

virt -- rump virtual network interface SYNOPSIS
#include <rump/rump.h> int rump_pub_virtif_create(int num); DESCRIPTION
The virt interface acts as a link between a rump virtual kernel and a host tap(4) interface. Interface number <n> always corresponds with the host tap interface tap<n>. All data sent by virt is written into /dev/tap<n> and all data read from /dev/tap<n> is passed as Ethernet input to the rump virtual kernel. A virt interface can be created in two ways: o Programmatically by calling rump_pub_virtif_create(). o Dynamically at runtime with ifconfig(8) or equivalent using the create command. Destroying a virt interface is possible only through ifconfig(8) destroy. The host's tap(4) interface can be further bridged with hardware interfaces to provide full Internet access to a rump kernel.

rump_smbfs -- mount a smbfs share with a userspace server SYNOPSIS
file-system PUFFS pseudo-device putter rump_smbfs [options] share mountpoint DESCRIPTION
NOTE! This manual page describes features specific to the rump(3) file server. Please see mount_smbfs(8) for a full description of the available command line options. The rump_smbfs utility can be used to mount smbfs file systems. It uses rump(3) and p2k(3) to facilitate running the file system as a server in userspace. As opposed to mount_smbfs(8), rump_smbfs does not use file system code within the kernel and therefore does not require kernel support except puffs(4). Apart from a minor speed penalty there is no downside with respect to in-kernel code. Even though the rump_smbfs file system client runs within a virtual rump kernel in userspace, it uses host network services (by means of ``rump sockin''). This means that regardless of whether using rump_smbfs or mount_smbfs(8), the same network configurations will be used. Currently, ``sockin'' supports IPv4. To use rump_smbfs via mount(8), the flags -o rump and -t smbfs should be given. Similarly, rump_smbfs is used instead of mount_smbfs(8) if ``rump'' is added to the options field of fstab(5). SEE ALSO
p2k(3), puffs(3), rump(3), mount_smbfs(8) HISTORY
The rump_smbfs utility first appeared in NetBSD 6.0. BSD
