worker has no heartbeat, restarting

[alirezakv]

with a clean installation on KALI, I repeatedly get this error in production.log while using GUI. And this causes GUI to become very slow and requests are not being answered. I don't get this error in Debian!

[MrSeccubus]

Does iot also happen if you run seccubus like this:

cd /opt/seccubus
morbo seccubus.pl

[alirezakv]

I used seccubus service to start it and this was the log:

but using morbo, GUI stops responding and will do nothing, does not show status page and does not login

[MrSeccubus]

So hypnotoad is rightfully killing haning child processes. The questions remains, why do child processes hang on Kali...

[alirezakv]

@seccubus if there is anything I can do to test tell me!

[alirezakv]

I just reinstalled the latest version from git (d6eb441 commit) on Kali and it seems that this problem is solved!

[MrSeccubus]

Does you comment in #568 mean I have unknowing resolved this issue now?

[alirezakv]

@seccubus I'm not sure but I encountered the issue when I upgraded from 2.28 to 2.38. After some investigation I saw that PERL5LIB only had "/opt/seccubus". So I did a clean installation and changed PERL5LIB to "/opt/seccubus:/opt/seccubus/lib" and the problem was fixed. So I guess the problem was about PERL5LIB.

[MrSeccubus]

Yes, that is the same thing that I encountered between releases 2.38 and 2.40. Also it seems debian has changed perl's behaviour not to have the current directory in the default clean path anymore...

Good, case closed for me, unless you object.

BTW would you mind writing up how you installed on Kali as that is a common question.

[alirezakv]

@seccubus
apt install perl mariadb-server libalgorithm-diff-perl libdbi-perl libdbd-mysql-perl libjson-perl libxml-simple-perl libwww-perl liblwp-protocol-https-perl libnet-ip-perl libtimedate-perl libhtml-parser-perl libcrypt-pbkdf2-perl libterm-readkey-perl libmojolicious-perl;
then install from source:
git clone ...
cd seccubus
./build_all
cd build
./install.pl --basedir /opt/seccubus
and then running deb postinstall script (which is only required for the first time)
This is how i'm doing it on kali!
about #533:
In debian repository we have mysql-server which depends on default-mysql-server (metapackage) which depends on mariadb-server so installing mysql-server will install maridb-server.
in kali repository we have default-mysql-server (metapackage) which depends on mariadb-server and there is no mysql-server.
deb file depends on mysql-server which will work on debian but not in kali!
