[Samba] samba4.2.0 crashes on connection attempt with an internal samba error...

Dear Samba fellows, 

I try to install samba on my notebook in order to get it into 
my samba based domain. It was a bit picky to get everything 
assembled on the notebook - but that last issue is hard. :-( 

I installed it from the sources on Debian Jessie - exactly 
in the same manner I used for my servers. I got sssd and 
kerberos working...

On the first attempt to connect to samba, it will crash however.

I have no clue, on where to start to debug this... 
I tried to add the libraries again, which are mentioned in the OS requirements. 
I also peeked around in the samba wiki's troubleshooting sections - but
without
any success. 

I could also post the smb.conf if necessary (and the krb5.conf and sssd.conf
files).
But I got all these from my working member server by just exchanging the machine
name. So I suspect the issue is hidden somewhere else. 

Thank You in advance! Any help is really appretiated.

I thought that Jessie was frozen, my idea of frozen and Debians seems to 
be different :-)

I installed jessie in a vm to test it, seeing as how sernet hasn't got 
round to releasing 4.2 packages yet and then Peter posted that he had 
got 4.2 running on jessie. I would love to know how he did this ?

I installed the packages to compile samba, well I tried to, this list of 
packages work on wheezy:

build-essential libacl1-dev libattr1-dev libblkid-dev libgnutls-dev 
libreadline-dev python-dev libpam0g-dev python-dnspython gdb pkg-config 
libpopt-dev libldap2-dev dnsutils libbsd-dev attr krb5-user docbook-xsl 
libcups2-dev acl libkrb5-dev libssl-dev xsltproc krb5-config libpam-krb5

Hmm, problem, libgnutls-dev doesn't exist on jessie, quick search seems 
to say that it has been replaced by libgnutls28-dev

So tried again, still doesnt work:

The following packages have unmet dependencies:
  libgnutls28-dev : Depends: libgnutls-deb0-28 (= 3.3.8-6~bpo70+1) but 
3.3.8-6 is to be installed
                    Depends: libgnutlsxx28 (= 3.3.8-6~bpo70+1) but it is 
not going to be installed
                    Depends: nettle-dev (>= 2.5) but it is not going to 
be installed
                    Depends: libtasn1-6-dev (>= 3.9) but it is not going 
to be installed
                    Depends: libp11-kit-dev (>= 0.20.7) but it is not 
going to be installed
  libldap2-dev : Depends: libldap-2.4-2 (= 
2.4.31+really2.4.40-4~bpo70+1) but 2.4.40-4 is to be installed

Added most of the above and tried again, it got worse:

The following packages have unmet dependencies:
  libgnutls28-dev : Depends: libgnutls-deb0-28 (= 3.3.8-6~bpo70+1) but 
3.3.8-6 is to be installed
  libgnutlsxx28 : Depends: libgnutls-deb0-28 (= 3.3.8-6~bpo70+1) but 
3.3.8-6 is to be installed
  libldap2-dev : Depends: libldap-2.4-2 (= 
2.4.31+really2.4.40-4~bpo70+1) but 2.4.40-4 is to be installed
  libp11-kit-dev : Depends: libp11-kit0 (= 0.20.7-1~bpo70+1) but 
0.20.7-1 is to be installed
  libtasn1-6-dev : Depends: libtasn1-6 (= 4.2-2~bpo70+1) but 4.2-2 is to 
be installed
                   Recommends: libtasn1-doc (= 4.2-2~bpo70+1) but it is 
not going to be installed
  nettle-dev : Depends: libnettle4 (= 2.7.1-1~bpo70+1) but 2.7.1-5 is to 
be installed
               Depends: libhogweed2 (= 2.7.1-1~bpo70+1) but 2.7.1-5 is 
to be installed

ARRGGHHH

Debian really need to get their finger out, come on, for example 
'libgnutls28-dev' it depends on version 3.3.8-6~bpo70+1 but 3.3.8-6 is 
to be installed, so for the addition of '~bpo70+1' it gets rejected.

I give up, I am going back wheezy and backports (4.2 builds on that) 
unless Peter wants to tell us how he built 4.2.

This sort of reminds me of the RPM hell that used to happen when red-hat 
was called red-hat and not RHEL.

[Samba] samba4.2.0 crashes on connection attempt with an internal samba error...

Oh. I am a pretty newbie on this field. Maybe that helped...

First I install the basic system including LXDE. On the problem loaden 
notebook I messed this up by an unsuccessful attempt to install the 
non-free Nvidia drivers - no way to get the history of this clear. 
Anyway, next I install ntp, xfs utilities. Next bind9 as slave DNS 
pointing to my AD DCs. On the notebook I used the Debian repository, 
on the servers I build from the sources as bind 9.9 hadn't been 
available during my first installations. 


apt-get --purge remove avahi-daemon

apt-get install build-essential libacl1-dev libattr1-dev \
   libblkid-dev libgnutls-dev libreadline-dev python-dev libpam0g-dev \
   python-dnspython gdb pkg-config libpopt-dev libldap2-dev \
   dnsutils libbsd-dev attr krb5-user docbook-xsl libcups2-dev acl \
   libncurses5-dev libssd-dev libkrb5-dev libpam-krb5



cd /to/bind/sources
./configure --prefix=/usr/            \
            --sysconfdir=/etc/bind    \
            --localstatedir=/var      \
            --with-libtool            \
            --with-openssl=/usr       \
            --with-dlopen=yes         \
            --enable-threads          \
            --with-gssapi=/usr/include/gssapi && \
make && \
make install


By then I install a dummy Bind9.9, i.e. without the AD related zones.
Next I install sssd and configure PAM. 


apt-get install sssd sssd-tools libnss-sss libpam-sss libsss-sudo \
      libsasl2-modules-gssapi-mit ldap-utils python-sss libsasl2-modules-ldap \
      cracklib-runtime libsss-nss-idmap0

I do fix the sssd and krb5.conf files here, even though it won't work 
until samba is compiled and running. 

apt-get install sssd sssd-tools libnss-sss libpam-sss libsss-sudo \
      libsasl2-modules-gssapi-mit ldap-utils python-sss libsasl2-modules-ldap \
      cracklib-runtime libsss-nss-idmap0

Then I start compiling samba.

apt-get install build-essential libacl1-dev libattr1-dev \
   libblkid-dev libreadline-dev python-dev libpam0g-dev \
   python-dnspython gdb pkg-config libpopt-dev libldap2-dev \
   dnsutils libbsd-dev attr krb5-user docbook-xsl libcups2-dev acl \
   libncurses5-dev libgnutls28-dev 

*) OK, in the meantime would replace libgnutls-dev by libgnutls28-dev,


apt-get remove xsltproc -> sonst "bus error"

./configure --prefix=/usr/local/samba \
            --with-piddir=/usr/local/samba/var/run \
            --with-syslog \
            --with-quotas \
            --with-acl-support \
            --enable-cups \
            --with-ads \
            --with-shared-modules=idmap_ad \
&& make 2>&1 | tee -i make.log \
&& make install 2>&1 | tee -i make-install.log


Next fix DNS, try Kerberos. Then join the machine, prepare the 
keytab on the DC, copy to the client and check SSSD. 
Typically then I'm done... Well, there is quite a bit of housekeeping... 
adjusting permissions, doing all the tests, doing a reboot etc.


On the problematic laptop I did some tests in the meantime: I installed 
the Debian package - problem still exists, and booted to the standard 
Debian kernel (otherwise I use 3.19.2) - also no progress. It really looks 
like some missing module. It seems to be related to authentication. 
But that is not exactly a clue... :-(

Best regards
Peter


PS: If I find some time, I will also set up a VM and try to install 
with libgnutls28-dev without libgnutls-dev being there in advance. 
But I can't promise. I have not much time over the weekend and in 
the course of the next week. :-(

[Samba] samba4.2.0 crashes on connection attempt with an internal samba error...

If you can, please recompile with CFLAGS=-g. Then, stop
smbd. Please install valgrind and run

valgrind --tool=memcheck smbd -d10 -i > valgrind.log 2>&1

Then try the connect. After it failed, please Ctrl-C the
valgrind and send us the valgrind.log together with your
smb.conf.

Thanks,

[Samba] [solved] Re: samba4.2.0 crashes on connection attempt with an internal samba error...

Dear Volker, dear list, 

while trying to prepare the debug information, I have been asked for 
by Volker, I fixed quite a couple of issues on the laptop. One of 
these things was the wifi setup - including a set of routes, which 
had been necessary while I've been logged into a network other than 
my home network. 

While the smb daemon still crashed during a connection test, it threw 
the tell tale message, that something with the join to the domain 
seemed to be wrong. I deleted the computer from the domain, did a new 
join - and the crashes had been gone. The lesson learn is this: 
while iterating through the steps of the setup, it is also adviceable 
to delete the problem burden computer from the domain and do a fresh 
join... 

Best regards
Peter
