Release Notes: This release fixes an authentication bug that would manifest as hung connections with protocols that send data from the client side before receiving data from the server side. The release further fixes a crash when attempting to enable packet capture for non-existing network devices. Various security features were incorporated. SELinux support was added.
Release Notes: This release adds support for syslog and compilation on Windows. It also enables tunneling over UDP port 53, and fixes a few minor bugs (in particular, ptunnel should no longer crash due to failed DNS lookups).
Release Notes: This version fixes a potential crashing bug when using authentication, which could affect both proxy and client. Ping Tunnel now opens the log file in append-mode instead of truncating it if it already exists.
Release Notes: This release adds support for authentication, allowing users to protect access to the ptunnel proxy using a password. This release also fixes a number of small bugs, and adds a man page.
Release Notes: This release fixes a locking bug and produces working executables on 64-bit computers. A number of other minor bugfixes have also been made, and support for logging to a file has been introduced.
Release Notes: This version fixed a byte-order bug that affected x86 systems.
Release Notes: This version adds support for timing out existing tunnels and limiting the maximum number of tunnels. A number of small bugs have also been fixed, hopefully enhancing stability for running many simultanous tunnels. An unofficial Windows port is now also available from ptunnel's homepage.
Release Notes: A problem introduced by the ICMP ID field changes was fixed. The proxy didn't retain the ID of the packets received from clients, resulting in dropped ICMP packets at the router. This in turn lead to the tunnel no longer working, depending on the strictness of the router. This version fixes that problem.
Release Notes: This version fixes an incorrect checksum calculation for resent packets. It no longer relies on the identifier field in ICMP packets, which should fix some problems in ptunnel's use. Finally, the default verbosity level has been changed from debug to verbose.
