Lan Problem: transfer pc<->nas, one direction faulty

[tobbegraf]

Hello,

i have a problem with my debian nas (Lenovo PC). It runs with debian stable and is connected with per 1gbit lan with a switch just like my desktop pc. For fatser transfers, i installed a 2.5gbit pcie card in the nas and the pc for a direct connection. After problems withe the driver (realtek r8125) the faster lan works for downloads from the nas but uploads to the nas will freeze the desktop pc (windows and linux).

After many tries with nfs and smb, cable testing etc. i have uninstalled the new 2.5gbit card, but now the old 1gbit shows the same error, no upload possible. As short test i use iperf. A test from the nas to any pc in the network with dual (-d) testing will never finish and freeze.

Even on a new, fresh install of debian, the old card shows the same error.

I tested grml live boot and ubuntu server and both run iperv in dual without problems from the nas.

Here a few infos:

card with e1000 is the old 1gbit card
card with igc is a new 2.5gbit card with intel chip.

it makes no difference if the new card is installed or not.

Thanks for any help

Hello,

Your computer has two network cards, the first directly wired to a NAS, the second connected to a network switch: have I correctly understood your configuration ?

Your output of the ip command shows both network cards (eno1, enp2s0) are recognized by kernel, but only one (eno1) is configured by the operating system.

Which program do you use to configure each of the two network cards ?

Can you verify / send the output of the following commands:

Code: Select all

script log.txt
cat /etc/network/interfaces
nmcli general status
nmcli device status
exit

Their output will be in the log.txt file.

Hello,

Sorry for the late answer!

I had no luck to get the two cards working in debian, even on a fresh installation. Still the hangups during transfer. I used the ip command to setup the addresses for testing and the files in /etc for the permanent settings.

In my desperation i installed Rocky Linux on the NAS (same PC, same switch, same cables) to get access to my data. There the Transfers works out of the box.

i will retry with debian, when i have more time or with the next major version.

thanks for your help!
