How to update accel-ppp

I will give an example of updating the accel-ppp, the commands need to be executed as root user.

First, see the current version of accel-ppp:

accel-cmd -V

Make a copy of the dictionary, if you previously made your own changes to it:

cp /usr/local/share/accel-ppp/radius/dictionary /usr/local/share/accel-ppp/radius/dictionary_copy

Ip-up and ip-down scripts with ipset for Accel-ppp

I’ll give an example of the scripts I used before, in the allowip list IP addresses were added to which the Internet is allowed, and in denyip those were redirected to the http page with information about the negative deposit.

ABillS + FreeRADIUS + Accel-PPP only issue one DNS

Once after installation ABillS + FreeRADIUS2 + Accel-PPP (ipoe) noticed that for DHCP clients receive only one DNS server.
Access-Accept from FreeRADIUS was this:

Sending Access-Accept of id 1 to 127.0.0.1 port 57481
        Session-Timeout = 604800
        PPPD-Downstream-Speed-Limit = 51200
        Framed-IP-Netmask += 255.255.255.0
        Framed-IP-Netmask += 255.255.255.0
        Acct-Interim-Interval = 600
        DHCP-Domain-Name-Server += 8.8.8.8
        DHCP-Domain-Name-Server += 8.8.4.4
        PPPD-Upstream-Speed-Limit = 51200
        Framed-IP-Address = 172.20.20.20
Finished request 40.

Reason for messages “HTB: quantum of class 10001 is big. Consider r2q change”

Once on the access server, Ubuntu Server 16.04 and Accel-ppp noticed the following messages in the /var/log/kern.log file:

kernel: [365970.550498] HTB: quantum of class 10001 is big. Consider r2q change.
kernel: [365970.550547] HTB: quantum of class 10A49 is big. Consider r2q change.
kernel: [365979.545580] HTB: quantum of class 10001 is big. Consider r2q change.
kernel: [365979.545621] HTB: quantum of class 10BD6 is big. Consider r2q change.

kernel: [365995.602031] HTB: quantum of class 11705 is big. Consider r2q change.

First I tried to track which interfaces are being raised at this moment:

tail -f /var/log/kern.log | grep "quantum of class 10001 is big"
tail -f /var/log/accel-ppp/accel-ppp.log | grep "create interface"

The script for adding IP addresses from a file to ipset

It took one day to write a script to add to ipset all the IP for which the session was started on the access server, Abills billing was used, so I decided to take IP addresses from the MySQL billing table.

The first step is to create a test ipset:

ipset create test iphash
