openvpn dns pushed on linux 2

posted on 2017-04-15 15:08

Last time I got this to work on debian (see here), now it was time to port this stuff to gentoo (there was more to it, this just to document that openvpn part).

needed packages

emerge -atv net-vpn/openvpn
emerge -atv net-dns/openresolv

resolvconf packages are deprecated it seems, openresolv is the new hotness.

openvpn config

These to lines need to be present in your .ovpn file at the end:

up  /etc/openvpn/up.sh
down    /etc/openvpn/down.sh

This differs from /etc/openvpn/update-resolv-conf in debian.

openvpn cannot find /dev/net/tun

Simple solution, just create the device if its not already present:

mkdir /dev/net
mknod /dev/net/tun c 10 200

Afterwards everything should work as expected, including the updated dns settings. Use watch -n1 -d cat /etc/resolv.conf to see things changing upon establishing and terminating the tunnel.

make it stick

After every reboot you'd have to recreate the /dev/net folder and device node. To let this happen automatically, create a file called /etc/local.d/create_tun_device.start containing:

#!/bin/bash
[ ! -d /dev/net ] && mkdir /dev/net
[ ! -e /dev/net/tun ] && mknod /dev/net/tun c 10 200

apache proxy ssl directives

posted on 2016-12-29 18:01

Likely you'd need these:

SSLEngine on
SSLProxyEngine on
SSLProxyVerify none 
SSLProxyCheckPeerCN off
SSLProxyCheckPeerName off
SSLProxyCheckPeerExpire off
SSLCertificateFile      CERTFILE
SSLCertificateKeyFile   PRIVKEY
SSLCACertificateFile    CACERTFILE

php session lifetime

posted on 2016-11-24 15:58

Adjusting php's session lifetime is a bit tricky. On why go to stackoverflow and read this.

Here is what you'd usually try:

session.cookie_lifetime = 7200  # cookie valid for two hours
session.cookie_path = /
session.cookie_domain =
session.cookie_httponly =
session.serialize_handler = php
session.gc_probability = 50  # with a probability of 50/1000 a session will be discarded after gc_maxlifetime
session.gc_divisor = 1000
session.gc_maxlifetime = 7200  # 2h until sessions are marked as outdated

This is nat a guarantee, its more like increasing the server's likeliness, to handle timeouts with the desired timef g.rame. Another possibility, on how to handle the timouts within the application itself, can be found in the link above, too.
