Samba doesn't work properly after update

[msdobrescu]

Hello,

After a long long time I have updated my Mageia machine.
Now, samba doesn't work properly anymore.

I have roughly found the issue, but I don't know how to fix:

[root]# smbclient -L 127.0.0.1
Enter myuser's password:
protocol negotiation failed: NT_STATUS_INVALID_NETWORK_RESPONSE

[root]# smbclient -L ::1
Enter myuser's password:
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.5.8]

::1 is an IPv6 address -- no workgroup available

What should I do now?

Thank you.

Please show your /etc/hosts content.
Seems your ipv4 loopback is broken or not working, as the second one is successful via ipv6 loopback (::1).

I guess it could be samba issue.

Code: Select all

netstat -tapn | grep smbd
tcp        0      0 :::139                      :::*                        LISTEN      9467/smbd

I have a Webmin working fine, I have disable the firewall.

[doktor5000]

Samba is listening on ipv6 loopback, how did you setup Samba?

[msdobrescu]

If I set these:

Code: Select all

    interfaces = eth0 lo
    bind interfaces only = yes

I get:

My smb.cfg is as follows (note: it worked before):

Code: Select all

# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not made any basic syntactic errors.

    # accounts on the fly, and maintaining a mapping of Windows RIDs to unix uid's
    # and gid's. winbind uid and winbind gid are the only required parameters.

    # here. See the man page for details.
    #   interfaces = 192.168.12.2/24 192.168.13.2/24

    # OS Level determines the precedence of this server in master browser
    # elections. The default value should be reasonable
    #   os level = 33
    os level = 20
   
    # Domain Master specifies Samba to be the Domain Master Browser. This
    # allows Samba to collate browse lists between subnets. Don't use this
    # if you already have a Windows NT domain controller doing this job
    #   domain master = yes
   
    # Preferred Master causes Samba to force a local browser election on startup
    # and gives it a slightly higher chance of winning the election
    #   preferred master = yes
   
    # 6. Domain Control Options:
    # Enable this if you want Samba to be a domain logon server for
    # Windows95 workstations or Primary Domain Controller for WinNT and Win2k
    #   domain logons = yes
   
    # if you enable domain logons then you may want a per-machine or
    # per user logon script
    # run a specific logon batch file per workstation (machine)
    #   logon script = %m.bat
    # run a specific logon batch file per username
    #   logon script = %u.bat
   
    # Where to store roaming profiles for WinNT and Win2k
    #        %L substitutes for this servers netbios name, %u is username
    #        You must uncomment the [Profiles] share below
    #   logon path = \\%L\Profiles\%u
   
    # Where to store roaming profiles for Win9x. Be careful with this as it also
    # impacts where Win2k finds it's /HOME share
    # logon home = \\%L\%u\.profile
   
   
    # The add user script is used by a domain member to add local user accounts
    # that have been authenticated by the domain controller, or when adding
    # users via the Windows NT Tools (ie User Manager for Domains).
   
    # Scripts for file (passwd, smbpasswd) backend:
    # add user script = /usr/sbin/useradd -s /bin/false '%u'
    # delete user script = /usr/sbin/userdel '%s'
    # add user to group script = /usr/bin/gpasswd -a '%u' '%g'
    # delete user from group script = /usr/bin/gpasswd -d '%u' '%g'
    # set primary group script = /usr/sbin/usermod -g '%g' '%u'
    # add group script = /usr/sbin/groupadd %g && getent group '%g'|awk -F: '{print $3}'
    # delete group script = /usr/sbin/groupdel '%g'
   
    # Scripts for LDAP backend (assumes nss_ldap is in use on the domain controller,
    # and needs configuration in smbldap_conf.pm
    # add user script = /usr/sbin/smbldap-useradd -m '%u'
    # delete user script = /usr/sbin/smbldap-userdel '%u'
    # add user to group script = /usr/sbin/smbldap-groupmod -m '%u' '%g'
    # delete user from group script = /usr/sbin/smbldap-groupmod -x '%u' '%g'
    # set primary group script = /usr/sbin/smbldap-usermod -g '%g' '%u'
    # add group script = /usr/sbin/smbldap-groupadd '%g' && /usr/sbin/smbldap-groupshow %g|awk '/^gidNumber:/ {print $2}'
    # delete group script = /usr/sbin/smbldap-groupdel '%g'
   
   
    # The add machine script is use by a samba server configured as a domain
    # controller to add local machine accounts when adding machines to the domain.
    # The script must work from the command line when replacing the macros,
    # or the operation will fail. Check that groups exist if forcing a group.
    # Script for domain controller for adding machines:
    # add machine script = /usr/sbin/useradd -d /dev/null -g machines -c 'Machine Account' -s /bin/false -M '%u'
    # Script for domain controller with LDAP backend for adding machines (please
    # configure in /etc/samba/smbldap_conf.pm first):
    # add machine script = /usr/sbin/smbldap-useradd -w -d /dev/null -c 'Machine Account' -s /bin/false '%u'
   
    # Domain groups:
    # Domain groups are now configured by using the 'net groupmap' tool
   
    # Enable priveleges, ie allowing members of Domain Admins to join machines
    # to the domain
    # enable privileges = yes
   
    # Samba Password Database configuration:
    # Samba now has runtime-configurable password database backends. Multiple
    # passdb backends may be used, but users will only be added to the first one
    # Default:
    # passdb backend = tdbsam
    # TDB backen with fallback to smbpasswd and guest
    # passdb backend = tdbsam smbpasswd guest
    # LDAP with fallback to smbpasswd guest
    # Enable SSL by using an ldaps url, or enable tls with 'ldap ssl' below.
    # passdb backend = ldapsam:ldaps://ldap.mydomain.com smbpasswd guest
    # Use the samba2 LDAP schema:
    # passdb backend = ldapsam_compat:ldaps://ldap.mydomain.com smbpasswd guest
   
    # Idmap settings (set idmap uid and idmap gid above):
    # Idmap backend to use:
    # idmap backend = ldap:ldap://ldap.mydomain.com
   
    # LDAP configuration for Domain Controlling:
    # The account (dn) that samba uses to access the LDAP server
    # This account needs to have write access to the LDAP tree
    # You will need to give samba the password for this dn, by
    # running 'smbpasswd -w mypassword'
    # ldap admin dn = cn=root,dc=mydomain,dc=com
    # ldap ssl = start_tls
    # start_tls should run on 389, but samba defaults incorrectly to 636
    # ldap port = 389
    # ldap suffix = dc=mydomain,dc=com
    # Seperate suffixes are available for machines, users, groups, and idmap, if
    # ldap suffix appears first, it is appended to the specific suffix.
    # Example for a unix-ish directory layout:
    # ldap machine suffix = ou=Hosts
    # ldap user suffix = ou=People
    # ldap group suffix = ou=Group
    # ldap idmap suffix = ou=Idmap
    # Example for AD-ish layout:
    # ldap machine suffix = cn=Computers
    # ldap user suffix = cn=Users
    # ldap group suffix = cn=Groups
    # ldap idmap suffix = cn=Idmap
   
   
    # 7. Name Resolution Options:
    # All NetBIOS names must be resolved to IP Addresses
    # 'Name Resolve Order' allows the named resolution mechanism to be specified
    # the default order is "host lmhosts wins bcast". "host" means use the unix
    # system gethostbyname() function call that will use either /etc/hosts OR
    # DNS or NIS depending on the settings of /etc/host.config, /etc/nsswitch.conf
    # and the /etc/resolv.conf file. "host" therefore is system configuration
    # dependant. This parameter is most often of use to prevent DNS lookups
    # in order to resolve NetBIOS names to IP Addresses. Use with care!
    # The example below excludes use of name resolution for machines that are NOT
    # on the local network segment
    # - OR - are not deliberately to be known via lmhosts or via WINS.
    # name resolve order = wins lmhosts bcast
   
    # Windows Internet Name Serving Support Section:
    # WINS Support - Tells the NMBD component of Samba to enable it's WINS Server
    #   wins support = yes
   
    # WINS Server - Tells the NMBD components of Samba to be a WINS Client
    #       Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
    #   wins server = w.x.y.z
   
    # WINS Proxy - Tells Samba to answer name resolution queries on
    # behalf of a non WINS capable client, for this to work there must be
    # at least one  WINS Server on the network. The default is NO.
    #   wins proxy = yes
   
    # DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names
    # via DNS nslookups. The built-in default for versions 1.9.17 is yes,
    # this has been changed in version 1.9.18 to no.
    dns proxy = no
   
    # 8. File Naming Options:
    # Case Preservation can be handy - system default is _no_
    # NOTE: These can be set on a per share basis
    #  preserve case = no
    #  short preserve case = no
    # Default case is normally upper case for all DOS files
    #  default case = lower
    # Be very careful with case sensitivity - it can break things!
    #  case sensitive = no
    case sensitive = yes

# Enabling internationalization:

BTW, I have used shorewall, so far.
Now, I see Invictus in MCC.
I have removed its package, but it is still there, in the MCC.
Is this a new 'standard'?

[doktor5000]

My smb.cfg is as follows (note: it worked before):

It worked before what? According to your posted netstat output samba is listening on ipv4 and ipv6 ip and loopback, and ipv6 link-local adresses.

Invictus lets you setup redundant firewalls: http://blog.mandriva.com/en/2006/10/06/ ... -firewall/
Here's also a (french only) wiki page about it: http://wiki.mandriva.com/fr/Invictus-firewall

[msdobrescu]

Yes, for almost 2 years it worked. First it was Mandriva 2010, then Mageia 1, by upgrade.
I did not change anything, except I have added the two lines:

Code: Select all

    interfaces = eth0 lo
    bind interfaces only = yes

Then, after the last bunch of updates, it stopped working.
Only samba has the issue. It could be some config changed by the upgrade. It could be some bug fixed (that allowed it to work before).
If you suspect something was changed during the upgrade, or if you see the issue, then enlighten me, please.
I have no clue, I have no big experience in networking.
PEBKAC.

[msdobrescu]

Are these rules the cause for that route?
I did not add them, they are probably added by the tools of MCC.

[doktor5000]

Have you tried clearing them up and resetting them via MCC?

[msdobrescu]

How could I clear them via MCC?
How could I reset them?
And most important to me, where could I find some scripts that creates the default rules at OS installation?
I need to know how should they look.

[doktor5000]

You can try either disabling the firewall or under services, stop shorewall and iptables services.

[msdobrescu]

I guess the rules in question are:

Code: Select all

iptables --list-rules |grep SMB
-A Drop -p udp -m multiport --dports 135,445 -m comment --comment SMB -j DROP
-A Drop -p udp -m udp --dport 137:139 -m comment --comment SMB -j DROP
-A Drop -p udp -m udp --sport 137 --dport 1024:65535 -m comment --comment SMB -j DROP
-A Drop -p tcp -m multiport --dports 135,139,445 -m comment --comment SMB -j DROP
-A Reject -p udp -m multiport --dports 135,445 -m comment --comment SMB -j reject
-A Reject -p udp -m udp --dport 137:139 -m comment --comment SMB -j reject
-A Reject -p udp -m udp --sport 137 --dport 1024:65535 -m comment --comment SMB -j reject
-A Reject -p tcp -m multiport --dports 135,139,445 -m comment --comment SMB -j reject


How could I find their source?
Where are they stored?
Are there config files?

[msdobrescu]

Analyzing the iptables rules, the above rules are skipped.
I am out of ideas.

[msdobrescu]

Eventually, I've found that adding allowed hosts as ips, it works.
Question is: why didn't it get them anymore by name, as long as the ping resolves them fine?
What could be wrong?
