Search and filtering in connections.cgi

Networking
1

Hi all,
inspired by Core 188 WUI changes - #15 by ms have made some changes in connections.cgi (under “Status” in WUI) and am searching for some critics, testings, enhancements and of course for constructive feedback.

The following has been enhanced →

clickable_legend-search_files-connections-cgi
clickable_legend-search_files-connections-cgi1517×336 23.5 KB

The main changes are

  • Added zone filter to select network zones (LAN, INTERNET, DMZ, etc.) via clickable legend.
  • Included NAT IPs in filtering for all zones.
  • Added search function to filter connections by IP, port, or protocol. With jQuery toggle on/off for search section.
  • Display filter status showing active filters and connection count.
    Have tested so far LAN, INTERNET, WIRELESS and IPFire (also in combination) legend tabs which worked so far some tests might be nice for the other parts according to the zones filtering. Have also tested the search filter which worked so far too, IP addresse can also be filtered by one, two, three or specific four octets.

If someone wants to check it, in here git.ipfire.org Git - people/ummeegge/ipfire-2.x.git/commit all can be found.
To integrate it, you can use the blob/raw format and !!!Please do not forget to backup the existing connection.cgi!!!

Feel free to give it a try and give some feedback.

Paralell project:
currently a little hacky!!! It should deliver configurable refresh cycles, configrable via WUI, and as before above cklicable zone filtering, search by IP, port and protocol is possible too.

Hi @siosios, you are one the right track since both should be (not that far) combined with another (realtime with a new graphical solution) but please use another channel for this since this is here currently OT.

Thanks and best,

Erik
