In WireShare tools, Under advanced filtering, Adding of IP addresses you would like to add to block, fails to work. You put in the full address and click ADD ok. But I notice it never adds the address to the box below. When I hit the ADD button the address just vanishes. Then after checking the running program it never takes effect. Bad hosts still enter in.

I don't have access to WireShare presently. It sounds like either you are closing the settings window without clicking OK button or you are not pressing the enter button when you wish to add the host.

Or due to the most recent hosts added being at the bottom of the list you have not scrolled down to the bottom of the list of blacklisted hosts. I recall it was far easier to scroll to bottom of the blacklist with LW 4 whereas with WireShare it can take a while depending on how many are in the list.

Thanks for the reply LOTR. I reloaded the program again just in case but it looks like you can't put any address in at all that it will accept, even my own. What it is doing is erasing the numbers you enter in after you click ADD.
Below the box is blank (checked or unchecked) for blacklisted hosts, so you can't scroll through anything. I assume the addresses I enter should pop up in the box after adding them though, correct?

I've been away and won't be back for another week. After that I can check the Windows version of WireShare to check what might be happening.

There's a small box you enter the single IP address into. It only accepts a single standard numerical IP address, not any address that includes the (mind block - reverse dns lookup) alternative name for the address with alphabetical letters. After typing or pasting in the address you press add or press enter on your keyboard and the number should then be seen in the list below. From memory I use both enter and add but I can't check at moment.
If you try to add a number with illegal characters (such as alphabetical letters) then it will fail to add.
e.g.:
Legal: 7.100.73.10
or 7.100.73.10/32

Illegal: rus.7.100.cable.73.10
or 7.100.73.10-32

Edit: Come to think of it, I think WireShare might have some limits on how large a block range can be. Or perhaps I'm confusing with LW 4. But you are unlikely to want to block such a massive range anyway.

I have that right yes, standard numerical addresses only, loaded and added one at a time.

I think I will load the older version of the program and see what it does.

I've now had the same results for two different versions of WireShare on
two different PC's using Win7. I only need to block a small number of hostiles, 3 or 4 would help.

I've just returned to discover I have hardware problems so I won't be able to test things out for some time.

Here's something you can try:

Find the WireShare.props file in your WireShare settings folder. Find a line that says either HOSTILE_IPS=
or BLACKLISTED ... =

Add the ip addresses you wish to and have a semi-colon after each one except the last one. Make sure there are no spaces.
eg:
HOSTILE_IPS=238.108.1.3;239.4.8.23

Save the document without changing the file format and do not choose any saving approach that creates a Rich Text type of document. Retain the .props file extension. See if that works.

I see "Download Settings" and "Torrent Settings" only. Where are the props files located?

Click on the Start button > type %appdata% into the text field > ok. You should now see a lot of folders - find the one named WireShare ... that is your preferences/settings folder.

For a more direct approach I think you can simply type in %appdata%\wireshare

By default the file extensions are normally hidden. So find a file within that folder called wireshare (that would normally be named wireshare.props)

Were you able to find the section of Wireshare props to add the addresses and did this work?

It has crossed my mind that your problem is a system permissions issue. You could try right-clicking the Wireshare program or shortcut and get Properties. Set Wireshare to 'Run as Administrator'. Only do this after WireShare has stopped running. I don't know if this will fix the problem of adding hosts to the blacklist but something worth trying.
