ICMP RTT bigger when channel is empty

9 hours 53 min ago
Dear all,

I want to evaluate the status of a network evaluating the RTT time of ICMP. My scenario is the following one where all nodes are linux server using networking kernel stack.

< Client> ----< Router 1>---------------<Router 2> ------<Server>

| |

<Traffic generator1> <Traffic generator2>

The problem I have found is when I do ping from Client to Server without extra traffic between Router 1 and Router 2 the RTT is bigger (1,9 ms ) than when I inject traffic with traffic generators to saturate the link. In this scenario RTT is around 1.5 ms.

As far as I know, this should not be the expected behavior. Do you know what is happening or have any clude to know how to fix it?.

Thanks in advance

VirtualBox guest windows don't open in XFCE with nouveau driver

10 hours 55 min ago
This is an odd problem (I think) that I discovered after switching from nvidia's proprietary driver to nouveau. In XFCE, with nouveau, the VB guest windows don't open but I can still hear the sound and the see the preview image in the VB interface. When I switch to Fluxbox the guest window works fine.

I've tried turining off compositing in XFCE and tried changing VB guest settings for video memory, graphics controller, and 3D accelleration. It previously worked in XFCE with the nvidia 390 series driver. I switched to nouveau after finding that was the only solution to a problem with HDMI resolution (again in XFCE but not in Fluxbox).

My system is Slackware64 15.0, kernel 5.10.99, xorg-server 1.20.14, XFCE 4.16, VirtualBox 6.1.40, GTX 750Ti

Thanks in advance for any ideas, and I can post any logs or configs you need to see

Nautilus search problems on Ubuntu 22.10 - Nautilus does not find files on one hard disk

14 hours 43 min ago
Hallo Forum,
maybe anybody could give me a hint how to solve a strange nautilus error:

For some reasons I did a fresh install of Ubuntu 22.10. (was 22.10) on a M.2 harddisk.

The hard disk has seperate partitions for / and /home.

I did copy my old docs to /home (copy paste the documents without any system files)

Everything is working fine... However if search the hard disk for files it keeps searching forever without results.
With a one letter search I still get files. With 2 letters it starts searching without result. There are no errors.

The search works for other hard disks... If I use catfish I get results. Reinstalling nautilus does not help. I have the pdf- compress script add on in Nautilus.

Thanks for any tips to fix.

How to detect and log a DSCP mark ?

16 hours 10 min ago
Hi everyone,

I am having trouble detecting and logging a given DSCP mark. I generate DSCP marking on the nodes that generate udp traffic:

'iptables -t mangle -A OUTPUT -s -d -j DSCP --set-dscp 46'

This works as expected (checked with tcpdump that the dscp field is correct)

Now the problem, is to detect in an intermediate node, that the incoming packet has the dscp marking equal to e.g., 46.

What I have done is:
- In the intermediate nodes, I have tried setting this (neither works):
iptables -A INPUT -p UDP -m dscp --dscp-class EF -j LOG --log-prefix "received packet with dscp=46"
iptables -A FORWARD -p UDP -m dscp --dscp 46 -j LOG

- I have also added to rsyslog.conf this line -> kern.debug /var/log/iptables.log -> then I restarted the service and now I get some output on that file, but nothing related when it receives packets with that dscp field mark

Thanks for reading!!

A new HPLIP for Slackware

17 hours 11 min ago
Hi guys.

For this time HP added support some a new printers:
but we stuck on hplip 3.20.5 version.

Well, we know that a new releases of hplip require avahi and Pat does not seem inclined to add avahi in Slackware. I agree with this.

So do we have any plans to update of hplip with network printing support in the future for Slackware or not?
