Bug 150791 – tun interface when using openvpn to set it up has txqueuelen 0

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Michael 2006-10-10 12:15:53 UTC]

tun interface when using openvpn to set it up has txqueuelen 0 which makes it unusable while setting by usermode-utilities, txqueuelen 100 (iirc). openvpn has option to set it --txqueuelen which is not used by baselayout script tuntap.sh

openvpn defaults to a txqueuelen of 100 - if this is not the case then something else is creating your tun interface.

No it's gentoo net scripts, i have only openvpn for creating tun/tap, no umlutils.

/etc/conf.d/net

tuntap_tap0="tap"
config_tap0=( "null" )

(setting ip does not help)

/etc/init.d/net.tap0 start
ifconfig
tap0      Link encap:Ethernet  HWaddr AA:6D:66:5A:2C:3E 
...
          collisions:0 txqueuelen:0

I've checked briefly openvpn sources and there is txqueuelen 100 as docs says but this do not work, I've set up manualy what net scripts do:

openvpn --mktun --dev-type "tap" --dev "tap0"

still the same
...           collisions:0 txqueuelen:0

It's look like upstream bug.

Yeah, openvpn bug.

Fixed in 2.0.7-r1 and 2.1_rc1-r1
