FAQ
===============
HTB: quantum of class is big
----------------------------
When an error appears in the logs:
.. code-block:: sh
HTB: quantum of class 10001 is big. Consider r2q change.
You need to set a parameter for the shaper:
.. code-block:: sh
#accel-pp will calculate the value itself
moderate-quantum=1
How to rotate logs ?
--------------------
You can use system logrotate utility for it. Put following file to /etc/logrotate.d
.. code-block:: sh
/var/log/accel-ppp/*.log {
missingok
sharedscripts
postrotate
test -r /var/run/accel-pppd.pid && kill -HUP `cat /var/run/accel-pppd.pid`
endscript
}
I don't see pppd processes, how to manually terminate session ?
---------------------------------------------------------------
Yes, in fact accel-ppp doesn't use pppd because it has its own ppp implementation.
To terminate session you may use three methods:
1. Use cli (telnet or tcp):
.. code-block:: sh
By default telnet listens connections on 2000 port and tcp on 2001 port.
$ telnet 127.0.0.1 2000
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
accel-ppp version 1.5.0
accel-ppp# terminate if ppp0
or
.. code-block:: sh
$ echo 'terminate if ppp0' | nc -q0 127.0.0.1 2001
There are also other criterias to select session(s), use help cli command to get more information.
2. Use radius Disconnect-Message:
.. code-block:: sh
$ echo 'NAS-Port=0' | radclient 127.0.0.1:3799 disconnect testing123
Received response ID 170, code 41, length = 20
and you can control it in logs:
.. code-block:: sh
[2012-01-21|16:48:55]: info: ppp0: recv [RADIUS|Disconnect-Request id=aa <NAS-Port 0>]
[2012-01-21|16:48:55]: info: ppp0: send [RADIUS|Disconnect-ACK id=aa]
3. Use snmp:
.. code-block:: sh
$ snmpset -m +ACCEL-PPP-MIB -v 2c -c local 127.0.0.1 ACCEL-PPP-MIB::termByIfName.0 = ppp0
