    [server] Re: After kernel update no zfs

    Good catch. It looks as though it might be a System76 kernel, but not sure. I am not aware of any falvour of Ubuntu using a 5.15 series kernel by default yet, even 22.04 development.

    Re: help with email spamming.

    Yes, I guess I was already writting my reply when you updated.

    I had assumed 192.168.19.22 was a typo and you had meant to write 192.168.0.19.

    Which version of Ubuntu?

    I wonder if somehow you have got a mixture of systemd-networkd and the old way going on at the same time. I am not an expert, and actually avoid using netplan entirely,...

    Re: help with email spamming.

    You don't know what 192.168.0.19 is? I can not help with that, because as you say it is on your LAN. The port involved is SSH, port 22.

    Just a guess below:
    Might you just so happen to have an SSH...

    [ubuntu] Re: [B]tcp contradiction[/B]

    Well, it seems to be working fine. UFW is just a front end for iptables.

    Potentially the issue is that the pi is using port 22, and sometimes iptables rules do not discern between source and...

    [ubuntu] Re: [B]tcp contradiction[/B]

    Is the Pi server 192.168.1.161 and the client 192.168.1.136?

    Could you also show us an example of at least one of your client's ssh listening ports. For example: "sudo ss -lntup'

    [ubuntu] Re: [B]tcp contradiction[/B]

    Does your pi server do all the backup work? For example does it "pull" the data from the clients? Could you show us the relevant portion of your client's sshd_config file. For example, here is one of...

    Re: Thoughts needed

    You appear to be back. Welcome. I hope the 9 month absence was beneficial.
  9. Re: kuula.co webpage not loading for version 20.04

    Works for me also. I used firefox browser (94.0.2 (64-bit)) from a windows 10 computer. And a Ubuntu 22.04 Desktop VM with firefox (94.0.2 (64-bit)). And a Ubuntu Desktop 20.04 VM with firefox 94.0.

    Re: help with email spamming.

    Thanks for reporting back.

    When you say you "got it from here" what do you mean? Do you mean from these forums? If yes, I don't think so.
    Also, what is "KS"?

    Re: Building Linux kernel (in Home folder)

    Suggest kernel 5.13 if you want to stay on that series. However, I recommend you try the latest mainline release, 5.15 or 5.16-rc3. Just steal the kernel configuration from the mainline PPA version,...
  12. Re: Kernel 5.16 RC (Release Candidate) series

    Kernel 5.16-rc3 is available. The Ubuntu mainline builds seem to have failed. I looked quickly at the log file, but didn't isolate the reason.
    I have been running for just a short time so far:

    While not exactly what you have asked for, my method for compiling the mainline kernel is detailed here. I have been doing it for years, and do keep the method in that link up to date.

    Re: help with email spamming.

    I have no way of knowing. I'll rephrase: It is email traffic involving 192.168.0.111. You will have to determine is it legitimate email or bad guy

    Re: help with email spamming.

    That is a DNS lookup response. You can tell by the use of port 53 on the DNS server end.


    O.K. so you have identified 192.168.0.111 as the source in the first example; 192.168.0.31 in the second...

    Re: help with email spamming.

    I'm not sure you will catch what you are looking for via the INPUT chain. I would log it, and/or block it, via the FORWARD chain, and with unique log prefixes, for extracting and sorting later on.

    Which you can without even changing tcpdump commands. The port 1433 one stays the same and the other one becomes:

    UFW generated iptables rules can be difficult to follow.
