• Timezones for ports and system.

Userland

Kernel

• iptables: Support for -m limit. For instance:

 /usr/sbin/iptables -t filter -A INPUT -p tcp --dport 2404 --sport 1024:65535 -m state --state NEW -m limit --limit 25/minute --limit-burst 100 -j ACCEPT

• tc: Basic support. For instance:

/sbin/tc qdisc del dev eth0 root    2> /dev/null > /dev/null
/sbin/tc qdisc del dev eth0 ingress 2> /dev/null > /dev/null

/sbin/tc qdisc add dev eth0 handle ffff: ingress
/sbin/tc filter add dev eth0 parent ffff: protocol ip prio 1 u32 match ip src 0.0.0.0/0 police rate 512kbit burst 1m drop flowid :1

/sbin/tc qdisc add dev eth0 root handle 1: cbq avpkt 1000 bandwidth 20mbit 
/sbin/tc class add dev eth0 parent 1: classid 1:1 cbq rate 512kbit allot 1500 prio 1 bounded isolated 
/sbin/tc class add dev eth0 parent 1: classid 1:2 cbq rate 512kbit allot 1500 prio 2 bounded isolated
/sbin/tc class add dev eth0 parent 1: classid 1:3 cbq rate 512kbit allot 1500 prio 3 bounded isolated

/sbin/tc filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip sport 22 0xffff flowid 1:3

GW6-1204

• IEC104: Respond to message sent to broadcast ASDU (0xFFFF)
• IEC-62056: mask incoming data with 0x7F (ASCII protocol)
• Serial ports: Suppress echo
• WebPage: Long awaited by all interenet browsers the favicon.ico

GW6-1202

• IEC104: Fix possible event loss on ethernet cable removal.
• Formula: Do not generate control event, on first successful calculation.

GW6-1200

• Firmware version readable through internal WebServer
• Fix possible event loss when lots of changes arrive for one input.
• GPRS-modem protocol: if connection to internet is lost, all TCP client connections are closed
• IEC104: force long-time format

GW6-1198

• IEC101/103 Unbalanced Master: add feature polling delay
• When sending a control operation over IEC103 channel with many devices. Speed up receiving of control response.

GW6-1196

• Connection loss with RTC-board does not result in watchdog reset.
  • Symptoms: device will reset after 20 seconds of running.
• Device will write system boot count and application start count to console.log. Latest values can be found in /var/local/telem/stats

RTA-A-1192

• RTA-A: possible to define DO object to clear annunciator LED 's
• Modbus Master: Fix receiving of negative 16bit normalized values.

GW6-1190

• Added new update pack type app-only.
  • Note: This update pack type should only be used on device with SW version 1190 or later.
  • This update will not overwrite system files - less chance for bricking if something goes wrong (accidental power loss or reset).
• Generate /etc/network/interfaces file once after receiving new setup.
• New protocol type IEC ^ Setup
  • Only reading and writing of device setup is allowed on this Port.
  • Allows faster booting of device with a lot of unused Up-channel ports.
