Release notes 7

NethServer release 7

Major changes on 2020-11-26

  • ISO release 7.9.2009 “final” replaces any previous ISO 7.8.2003

  • The old Server Manager (namely Nethgui) is not available by default on new installations. To configure the system access the new Server Manager on port 9090.

    Old Server Manager can be still installed from Software Center.

  • CGP (Collectd Graph Panel), EveBox, Rspamd UI, Lightsquid and Ntopng are still available on HTTPS port 980, even if the old Server Manager has not been installed.

  • On new installations, users belonging to the wheel group are now granted SSH and SFTP access. Note that users created by the Anaconda ISO installer can be members of wheel. See SSH for details.

  • On new installations, SSH weak ciphers are now disabled by default. To enable weak ciphers uncheck the Disable weak ciphers option inside the System -> SSH page.

  • Default TLS policy is 2020-05-10. TLS 1.1, TLS 1.0, SSL v3, and SSL v2 are disabled. See TLS policy for details.

  • New installations of Nextcloud honor the StartTLS setting of the Active Directory accounts provider. As old installations ignore that setting and always send clear-text passwords, it is recommended to upgrade them to the new behavior. Make sure the remote AD accounts provider supports StartTLS, then run the following commands

    config setprop nextcloud HonorAdStartTls enabled
    signal-event nethserver-sssd-save

    Finally check that the StartTLS option is enabled in System > Users & Groups > [Account provider] > Edit provider. See also LDAP account for additional applications.

  • To prevent errors during Nextcloud upgrades, the mail application has been disabled. After each upgrade, the application should be manually updated and re-enabled by accessing Nextcloud administration interface.

  • Netdata is now installed by default to serve charts for the Server Manager. Some plugins have been disabled to reduce resource usage. To enable those plugins see netdata configuration .

  • After nethserver-ndpi installation a reboot is needed if the running kernel version is less than 3.10.0-1160.6.1.el7.

  • Mattermost DB was upgraded to PostgreSQL 12. The PostgreSQL 9.4 instance is stopped and disabled automatically by the nethserver-mattermost upgrade procedure if no other service requires it.

    1. Ensure the old service is stopped and disabled:

      systemctl status rh-postgresql94-postgresql
    2. PostgreSQL 9.4 can be uninstalled with the following command:

      yum remove nethserver-postgresql94
  • DAHDI tools and kernel module are no longer installed by default as part of nethserver-freepbx package. If the system needs DAHDI software for special telephony related hardware, install it from Software Center by selecting the DAHDI drivers and tools module.

    On updated machines where DAHDI is not required, these packages can be removed with the following command:

    yum remove dahdi-tools-libs dahdi-linux kmod-dahdi-linux dahdi-firmware
