note: i run packet sniffer, capture packets of BGP session

i see then keepalive messages and at one point tnsr with IP 10.62.40.245 sends TCP FIN and closes connection without any obvious reason

@sheebz said in TNSR on Proxmox:

@jimp ahh it needs 3 virtual nics? my server has a dual 10g nic, but i do have a node with 2 more 1gig nics. will that work? or does it have to be 3+ nics on the main machine?

It's possible to run with two (e.g. internal and external) in the dataplane only but TNSR works best when you have a management interface. The host management itself doesn't use the dataplane network, it's separate. That doesn't need to be real, it could be internal to Proxmox on a bridge to somewhere else you have a management client. There are ways to nudge things to use the dataplane from within the host for tasks like OS updates, so it's not a complete non-starter, it's just not an ideal setup.

@derelict yes i see ipfix dont giving all data sending only nat data

we cant use fastnetmon right now

if possible please add sflow exported on next version

@derelict

Well there is this page suggesting it could be supported.
https://doc.dpdk.org/guides/nics/axgbe.html
Dunno if the Epyc Embedded 3000 are the same as Ryzen Embedded regarding the NIC. Cannot find much about that.

As I own a system with a v1500b inside maybe I will just try and install TNSR and see what happens.

@indianatux OK thanks for trying that.

@jimp Thanks, I have since found that out.

Heads up for anyone else trying to get this working on CentOS, the information you are looking for to get this working is to specify the NetworkNamespace="dataplane" in your rsyslog.conf configuration. This would have been a useful tip as it goes off the typical, basic, default config in rsyslog and specific for the TNSR config.

example config for my rsyslog.conf that work for me in CentOS 8:-
action(type="omfwd"
queue.filename="tnsr_syslog"
queue.maxdiskspace="1g"
queue.saveonshutdown="on"
queue.type="LinkedList"
action.resumeRetryCount="-1"
Target="example.com" Port="514" Protocol="udp" NetworkNamespace="dataplane")

@dans I might be about to have a similar setup as yours. How did it end?
Thanks from a fellow "Dan"

@jimp Thank you sir

@viragomann My question about TNSR Home+Lab setup.

Thanks jimp. Maybe just a newbie issue. Anyway, I've got an initial build up now. Throughput is about twice as fast as testing I've done with FreeBSD packet filters but still tops out at about 3-4Gbps. I'm hoping I can improve this with tuning.

Looking forward to the next release. Debian distro's are my preferred Linux flavour 👍
