Oh, and to reduce code duplication, you could use "tee -a device.log" here. Also, since this recurs a number of times, maybe you could break it out into its own little function. That would be my main stylistic suggestion actually -- see which parts you could modularize into functions.

All of the sudden scp got really slow ... from 2-3 seconds to 30 seconds.
This happened for 5 hours, and then it went back to running fast.
Why?
If I use the -q qualifier which "Disables the progress meter" could this have any adverse effect?

ls displays files in tabbed output. Say a directory contains 3 files. ls will list all 3 in one line. So, I expect ls | wc -l to give 1, but it counts the nr of files and gives 3.
Can someone explain how this works? (3 Replies)

vde_tunctl
VDE_TUNCTL(8) System Manager's Manual VDE_TUNCTL(8)NAME
vde_tunctl -- create and manage persistent TUN/TAP interfaces
SYNOPSIS
vde_tunctl [-f tun-clone-device] [-u owner] [-t device-name]
vde_tunctl [-f tun-clone-device] -d device-name
DESCRIPTION
vde_tunctl allows the host sysadmin to preconfigure a TUN/TAP device for use by a particular user. That user may open and use the device,
but may not change any aspects of the host side of the interface.
vde_tunctl is a simple copy of tunctl done for practical purposes.
USAGE
To create an interface for use by a particular user, invoke tunctl without the -d option:
# vde_tunctl -u someuser
Set 'tap0' persistent and owned by uid 500
Then, configure the interface as normal:
# ifconfig tap0 192.168.0.254 up
# route add -host 192.168.0.253 dev tap0
# bash -c 'echo 1 > /proc/sys/net/ipv4/conf/tap0/proxy_arp'
# arp -Ds 192.168.0.253 eth0 pub
To delete the interface, use the -d option:
# vde_tunctl -d tap0
Set 'tap0' nonpersistent
