trex v3.05 on Ubuntu 24.04 with Kernel 6.8 and Python 3.12 doesn't work

[freddy.b...@gmail.com]

Hi,

We are deploying a baremetal ubutnu in a beefy server with 56core and 768G RAM

The server is a UCS 240 with severals NIC including a Intel Corporation 82599ES 10-Gigabit (4 ports) and a Cisco VIC 1455 (4 Ports) all of them at 10GigE

OS is Ubuntu 24.04

6.8.0-39-generic #39-Ubuntu SMP PREEMPT_DYNAMIC Fri Jul  5 21:49:14 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

Python is version 3.12

Scapy is version 2.5

When trying to use ./dpdk_setup_ports.py -i this parsing errors appears

/opt/trex/v3.04/./dpdk_setup_ports.py:62: SyntaxWarning: invalid escape sequence '\d'
  _2hex_re = '[\da-fA-F]{2}'
/opt/trex/v3.04/./dpdk_setup_ports.py:511: SyntaxWarning: invalid escape sequence '\d'
  ofed_ver_re = re.compile('.*[-](\d)(\d)?[.](\d)(\d)?[-].*')
/opt/trex/v3.04/./dpdk_setup_ports.py:863: SyntaxWarning: invalid escape sequence '\s'
  ifname_re = re.compile('iface\s*=\s*([^\s,]+)')

Those Warning messages shows all over at any command

The current config is for loop testing

Start the trex server on interactive mode error out with missing scapy server, and even if you start it with the --no-scapy-server flag, the trex-console does not work

sudo ./trex-console -s 127.0.0.1

I have been trying some other combination but nothing seems to fix the issue.

any guidance will be appreciated

i am getting similar syntax errors on ubuntu 24.04 with whatever version of Trex I use; i moved to another vm with Centos Stream 9 and the syntax errors have gone away; however, now I am getting hugepage errors.

[Hubert Hans]

On my Ubuntu with Kernel version 6.8.0-40 Trex 3.04 stopped working with my x710 (cannot aquire ports for dpdk) and after i stick my 225v into my machine and using trex 3.05, i have gotten the hugepage errors, also.

I will go for CentOS now, but i doubt it will solve my problems. The Old Centos 7.6 is downloading, too. But i dont like to use it because of its age. It will be my last resort

[Hubert Hans]

PS: I updatet Ubuntu today, like everyday if i want to run around with my Trex. But that was a huge mistake, some people got bitten, as it seems.

With Centos Stream 9 Trex 3.04 now works fine. For now...

Has anyone been able to install Trex on ubuntu 24.04  or the latest version of Rocky linux? I am having similar issues

Hi Foday,
