    Default nethogs and jnettop: segmentation fault

    Hi all,
    today I was trying to diagnose a unexpected sudden surge in network activity, so I tried to use nethogs, but it crashed with a segmentation fault.
    So I tried to use jnettop, but it crashed with a segmentation fault, too.

    Let alone jnettop, which is not an "official" package, nethogs comes from the download.opensuse.org-oss repository and so I would not expect it to crash.

    Any hint?
    If you need more details I'll be happy to provide them.

    Thank you in advance.

    On my TW, jnnettop packages don't exist.

    After doing a "dup,"
    Searching in the OSS doesn't return the package.

    Then, I took a look at the following which is really messed up... It installs the "server:monitoring" repo, but also a dependency from the "Factory:ARM" repo, and of course I don't want anything from that repo on my x86 machine. Re-inspecting what is in the "server:monitoring" repo, there is only a source package for jnettop, not the application itself (is it intended to be built on the fly when installed?).
    https://software.opensuse.org/packag...h_term=jnettop

    The traditional tools which only collect data for later analysis (not typically viewable in real time) are
    tcpdump
    wireshark

    To view in network traffic in real time with a graphical app, I highly recommend etherape.

    Hi tsu2, thank you for your reply.
    Yes, jnettop is not an official package (meaning it doesn't come from one of the official tumbleweed repositories). I got it from this address.
    That is why I am not really concerned with jnettop.

    On the other hand, nethogs *is* an official package so I would not expect it to crash with a segmentation fault.

    BTW, thank you for pointing me to etherape, I'll check it ASAP.

    Others are reporting problems with various ncurses-based programs on the opensuse-factory mailing list.

    It seems there is a problem with ncurses on TW:
