I just upgraded OpenSUSE from Leap 42.3 to Leap 15.0, and with this upgrade, OpenSUSE moved its default firewall application from SuSEfirewall2 to Firewalld. I opted not to use the susefirewall2-to-firewalld script for migration, but to rebuild my rules from scratch. However, I cannot seem to allow NetBIOS queries to return successfully on my client machine. I have enabled both the samba and samba-client services in Firewalld.



For a host hostname, which I can ping because of DNS or access by IP address, and from which I can access my OpenSUSE machine via Samba, I try:



> nmblookup hostname
name_query failed to find name hostname


What else do I need to do to allow a NetBIOS query to succeed?






opensuse firewalld

          As a result of a discussion about this issue from the Fedora Mailing-Lists, I added port 137 UDP to the Source Port list for the samba-client Service in Firewalld (with the firewall-config tool), which enabled the nmblookup call to succeed.

                    Postfix configuration issue with fips on centos 7; mailgun relay

                    Image
                    Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I am trying to setup postfix to relay all mail generated on the local machine via SMTP to a mailgun relay. I have used the mailgun relay before with success on an ubuntu server, but I am migrating to a Centos 7 server which I will be running in FIPS mode. There error log is below, slightly sanitized. I have a small enough network that I choose to have each machine reach out to mailgun individually (this the loopback-only, 127.0.0.0/8 restrictions) and no firewall open port allowing smtp in to the machine. I assume the FIPS mode (and with it disabling of MD5) is causing problems, but I don't know how to overcome it or if it is even possible for tls_fprint to use some supported hash such as sha256 or sha512. However, the relay=none is slightly concerning since I have relayhost set, but perhaps that is because the smtp process is failing? Any help would be appreciated! postconf -n: alias_database = hash:/etc/alia
