Re: intel x520 not using all the rx queues

From memory, the X520 does not have more than 16 queues and therefore cannot allocate more to each CPU, etc.

Re: Problem with Vlan-mon and Intel X710/X722

Re: accel-ppp stops processing packets when RADIUS is unavailable

I'm not sure that I understand why increasing that make any discernible difference? Looking at the code, all that would do is merely delay the same problem from happening maybe 1 second later? The issue is if the RADIUS server is unavailable for let's say an hour, the entire accel-ppp stack stops wo...

accel-ppp stops processing packets when RADIUS is unavailable

Hi I've noticed accel-ppp stops processing packets for PPPoE and L2TP type services when RADIUS services become unresponsive or slow. My guess is that the request queue is overwhelmed with RADIUS requests and it stops or slows processing others to almost a halt as all threads become busy/overwhelmed...

Plugins?

I noticed in the RADIUS code there's infrastructure for a rad_plugin_t and plugins. These seem to be able modify requests. However, there's no where to specify them or load them in the configuration. Am I misunderstanding the purpose of this code or is it mostly there but just missing some surroundi...

Re: So I had put accel-ppp live with heavy load

I'm using Debian 9 but your issue sounds like it is more network related. Check your NIC buffers and your switch port buffers and statistics.

Re: So I had put accel-ppp live with heavy load

I'm running accel-ppp on multiple servers each doing 3Gbps load with mixture of PPPoE and L2TP without issue (touch wood) using 10-Gigabit X540-AT2, 4.9.0-11-amd64 and 8 x E3-1270 and accel-ppp has been running for about 150 days with ~1000 sessions. Can you scale horizontally?

Re: accel-ppp as a L2TP LAC?

No solution. I was hoping @dimka88 might shed some light if this is possible with the current code or if I need to try and patch it so I don't spend a hours trying to work it out.

Re: L2TP internal queue is never drained resulting in no new sessions allowed

Looking further at this, because it keeps happening, I've gathered the following logs (with some extra debugging entires added by me): [2020-05-27 10:25:01]: info: l2tp tunnel 20306-17769 (1.2.3.233:1701): retransmission #1 [2020-05-27 10:25:01]: info: l2tp tunnel 20306-17769 (1.2.3.233:1701): retra...

Re: Adding PPPoE interface with QinQ with accel-cmd misses inside tag

That does not solve the problem and in fact, makes it worse in the following use case: 1. You cannot run say: accel-cmd# pppoe interface add eth3.2702.1200 Without the interface eth3.2702.1200 being up. Usually, the interface associated with the c-tag will be auto-created by accel-ppp. Therefore, I ...
