23 maggio 2018

IPFire

IPFire

IPFire è una distribuzione Linux orientata al networking, che offre, modularmente:

  • Firewall
  • Web Proxy
  • VPN Gateway
  • Intrusion detection
  • Quality of Service
  • Virtualizzazione
  • Wireless access point

Il tutto pensato per essere semplice da configurare ed è costantemente aggiornato.

Versione 2.19 Core 120

Questa versione contiene (in Inglese):

RAM-only Proxy

In some installations it might be desirable to only let the proxy cache objects in memory and not on disk. Especially when Internet connectivity is fast and storage is slow this is most useful.

The web UI now allows to set the disk cache size to zero which will disable the disk cache entirely. Thanks to Daniel for working on this.

OpenVPN 2.4

IPFire has migrated to OpenVPN 2.4 which introduces new ciphers of the AESGCM class which will increase throughput on systems that have hardware acceleration for it. The update also brings various other smaller improvements.

Erik has been working on integration this which has required some work under the hood but is compatible with any previous configurations for both roadwarrior connections and net-to-net connections.

Improved Cryptography

Cryptography is one of the foundations to a secure system. We have updated the distribution to use the latest version of the OpenSSL cryptography library (version 1.1.0). This comes with a number of new ciphers and major refacturing of the code base has been conducted.

With this change, we have decided to entirely deprecate SSLv3 and the web user interface will require TLSv1.2 which is also the default for many other services. We have configured a hardened list of ciphers which only uses recent algorithms and entirely removes broken or weak algorithms like RC4, MD5 and so on.

Please check before this update if you are relying on any of those, and upgrade your dependent systems.

Various packages in IPFire had to be patched to be able to use the new library. This major work was necessary to provide IPFire with the latest cryptography, migrate away from deprecated algorithms and take advantage of new technology. For example the ChaCha20-Poly1305 ciphersuite is available which performs faster on mobile devices.

The old version of the OpenSSL library (1.0.2) is still left in the system for compatibility reasons and will continue to be maintained by us for a short while. Eventually, this will be removed entirely, so please migrate any custom-built add-ons away from using OpenSSL 1.0.2.

Misc

  • Pakfire has now learned which mirror servers support HTTPS and will automatically contact them over HTTPS. This improves privacy.
  • We have also started phase one of our planned Pakfire key rollover.
  • Path MTU Discovery has been disabled in the system. This has continuously created issues with the stability of IPsec tunnels that have chosen paths over networks that were incorrectly configured.
  • The QoS template could miscalculate the bandwidth which has now been fixed that the sum of the guaranteed bandwidth over all classes does not exceed 100%
  • Updated packages: bind 9.11.3, curl 7.59.0, dmidecode 3.1, gnupg 1.4.22, hdparm 9.55, logrotate 3.14.0, Net-SSLeay 1.82, ntp 4.2.8p11, openssh 7.6p1, python-m2crypto 0.27.0, unbound 1.7.0, vnstat 1.18

Add-ons

These add-ons have been updated: clamav 0.99.4, htop 2.1.0, krb5 1.15.2, ncat 7.60, nano 2.9.4, rsync 3.1.3, tor 0.3.2.10, wio 1.3.2

  • asterisk’s documentation is now included in the package which has been missing earlier and rendered asterisk unable to start
