This firmware update is based on our last Stable Release from December; it rectifies some partly very important mistakes. In addition, the new CDMA 450MHz module types are supported for the first time by this firmware release. The command line interface (CLI) is now ready for production use.
We recommend all customers to update to this stable firmware release as soon as possible. Please note that all Hubs and Routers should be updated to this release. Routers with this current firmware are able to talk to Hubs with older firmware (and vice versa), but performance may be degraded.
- This release for the first time fully supports our new CDMA 450 Mhz modules to be used in northern and eastern Europe.
- Channel congestion detection is slightly changed to be more aggressive.
- The CLI has been completed and is now ready for production use. A scripting toolkit to automate router administration and deployment is available on request.
- IMPORTANT: The previous stable firmware released on December 10th has a very dangerous bug: If you have references in the VPN & Routing object to a Tunnel, and then in the Tunnellist remove a Tunnel previous to such a referenced Tunnel, all routing references would break, potentially killing all of your routing configuration. The same happened with QoS rules references. Do not delete any Tunnels before upgrading to this firmware release!
- If channels were completely idle (traffic less than 20 kbit/s for a while), they were supposed to only send the internal pings for latency and loss management every 1000ms instead of the default 100ms. This was meant to reduce idle traffic usage over expensive links like UMTS. This feature always has been broken due to a rounding error. Once you ever on a connected channel had more than 24 Kbit/s, it would never go back to this idle-traffic-saving mode. This now works as expected and will reduce idle traffic usage by a factor of 10.
- In Hotspare mode, the license manager now displays a note that licenses are not checked in this mode.
- A rare timer overrun on the 500 could cause short hangs of the routing.
- The Ethernet info tool for the LAN interface of the 500 now actually works.
- Multiple BondingTCPOptimizer bugs were fixed. Those could cause a BondingTCPOptimizer TCP connection to hang if the bottleneck in bandwidth has not been the tunnel, but on the LAN instead (e.g. if you had a traffic shaper behind a Viprinet router).
- Ethernet Autonegotiation settings for Ethernet WAN Modules were not saved across reboots. This is now fixed. Known issue: Gigabit Ethernet Modules right now do not support turning off Auto Negotiation at all due to a NIC driver bug. You can only turn off Auto Negotiation for Fast Ethernet modules.
- A memory leak in regards of Tunnel objects was fixed. If you created and deleted a huge number of VPN Tunnels using scripting, the router could run out of memory with previous firmware releases. This no longer happens. Also, performance of this kind of mass additions/removals has been improved.
- In the previous stable firmware release, it was changed that after a big number of critical errors in the log, the router would automatically reboot. However, if one of the two redundant fans breaks, this is logged as critical error. This caused routers with a broken fan to constantly reboot every few minutes. This issue is now fixed - a single broken fan is no longer reported as critical, but as an alert. Only both fans failing is now critical.
- An "invalid floating point error" could appear when using the download tool with "Measure & discard" setting.
- When using e.g. plink to supply a file of commands that are to be executed via the CLI, carriage returns were ignored and no command separators existed.
Example:
plink -pw -batch -ssh -P 22 root@ -m commands.txt -v ERROR 140 ←[1m←[31mThis object does not exist←[0m
This now works with CR or CR/LF as command seperator.
- The CLI now allows to delete items using their object index instead of object names only, e.g. "execute DELETEITEM OBJECT__2".
- The CLI now properly supports closing the SSH connection, and closing/reopening SSH subchannels to issue multiple commands in a way that some SSH scripting toolkits (e.g. Paramiko) do it.
- Multiple typos have been fixed in the web interface.
- The timing of Hubs placed in a redundancy group probing to check if they are replaced on boot has been modified to be more robust.
- BondingTCPOptimizer connections seeing packet loss on the WAN with unstable high-bandwidth links could, after internal retransmission of lost segments, have queued up a very big amount of packets on the LAN side (multiple megabytes). This could cause huge traffic spikes when those were released to the LAN, potentially causing problems on the LAN which could be seen on the routers as "XX packets have been dropped reading from LAN" messages. These packets will now be released more slowly to reduce these spikes.
