I just installed Comodo and it won't allow P8 to show my library.  I gave it permission and all but still no library.  Any suggestions?

It needs to be allowed to listen and talk to 127.0.0.1 port 11530.

I don't know Comodo so can't give specific instructions.

Problem solved... thanks...

ok, so why does it need to access the internet in order to display the librarys?

what happens if you have to cancel your internet service for awhile, that meanyou can't use poser 8 until you can afford to have the internet again?

Attached Link: 127.0.0.1 / Localhost / Loopback explained

it's using the Loopback Adapter - 127.0.0.1 - this has nothing to do with internet access at all.

The address 127.0.0.1 means call my own phone number, without using the telephone company. It's like using your phone handsets as an intercom. Don't worry about it. I'll explain it later after you've had a few years of computer science. LOL Just kidding.

Really, Poser does not use the Internet. It uses TCP/IP. Want to learn more? Google.

On my system it wants to use the public IP address (80.220.XX.255 UDP port 11423)

That's something different, the check for multiple copies with the same serial being used on more than one machine on the same network (which has been in Poser since P3 IIRC).
You'll see this if your machine is directly connected to your ISP's network rather than through a router (when it will only look on the local network that that provides).

Which raises an interesting qustion. Why bother with mutti-copy checks over the local net when anybody nowadays, practically without doing anything special, will have a firewall that prevents it from finding other copies?

Right, I forgot about that.

Allowing just localhost doesn't work either, the library still remains blank.

 hoplaa, have you tried updating to SR1?  It solved the library issue for me.

I'm using SR1, and the library works when I give Poser 8 full access.

 When you "just allow localhost", how are you doing this?  via your firewall?  Is your PC set up as a "server" of sorts in your home network?

(These aren't anything I've come across, just things that, in my mind, might be affecting your computer)

No serving here, our ISP gives our two computers public IPs which are not in the same subnet.

I had two rules set up in the firewall (Comodo), one to allow all traffic from/to localhost and another to block everything else. This caused the library to remain blank. If I block everything, there's an error message in the library window. If I allow everything, the library works.

I don't have experience with Comodo, so please excuse my ignorance.  When you set it to allow Poser to contact the localhost, is it actually allowing the contact, or is it filtering it?  I know that, in my husband's line of work, he literally has to fix people's firewalls so they can actually get on the internet, because their firewall is filtering all access, even though it's "set" to allow contact.  It may very well be that, in allowing network access to Poser, it's the only way to get localhost access unfiltered.
Also, just on a whim, you don't have "automatic updates" checked "on" in your preferences, do you?

Agreed.
Just another bit of legacy code from an era when per machine firewalls were practically non-existent that could be pruned.
I suspect that as multiple machines and home networking were also rare at the time, it was aimed more at companies than hobbiests.

hoplaa,

Shot in the dark. Not all systems correctly equate localhost with 127.0.0.1. I didn't mention localhost for that reason. I said 127.0.0.1, port 11530.

Perhaps the OP can come back and just say how to configure comodo in plain English?

By the way, if the part you're configuring is what traffic to allow in and out from your attached network, this is pointless. 127.0.0.1 traffic is, by definition, not over the network. It is internal to the computer, like an intercom.

Again, I don't know comodo, but there is an architectural distinction here - a firewall between your comm stack and the physical hardware is not the same as a firewall inside the top level of the comm stack.

Allow localhost = allow IP in/out source 127.0.0.1 destination 127.0.0.1
With this alone it doesn't work.

A new discovery... If I add a rule to allow IP out from any to any, then it works. Am I to conclude from this that Poser 8 is not in fact communicating as localhost? Or what? I don't get it :(

Notification of updates is enabled in Comodo, although I haven't actually updated it in a while. If that's what you meant.

Edited to add that this is satisfactory, although I'd like to know what exactly is happening here. Thanks for your time anyway :)

allow IP any to any is wide open, same as not using a firewall. It is a door with all parts transparent.

Poser 8 is allowed to connect anywhere, but incoming connections are only allowed from localhost (notice I said IP OUT from any to any). I'd say this is secure enough, do you disagree?

Edited to add, for the sake of clarity, here are the two rules currently setup for Poser 8:
allow IP out from any to any
allow IP in/out from localhost to localhost

Installed P8 on the other computer which has Windows 7 and its own firewall which is configured to block outgoing traffic. No problems there.

The UI animations are misbehaving though. You know how the buttons highlight and then the effect fades out when you move the pointer away from them. This effect is really slow on the other system (W7, Radeon 4770, latest Catalyst). Doesn't affect usability, but a glitch is a glitch.

I didn't really do anything with it yet though other than confirm that the library is working.

Honestly... now I'm stumped and ridiculously frustrated with Vista and Comodo.  For a while, it worked and I could see my library.  I didn't even do anything and it all of sudden started letting me see my library.  Now all of a sudden it's not.

I've gone into the basic commands of Comodo and set P8 as a trusted app.  That didn't work.

I've gone into the firewall settings of Comodo.  You can go into the advanced settings and add what Hoplaa said to add.  That didn't work.  I set it as a trusted app, I set it to allow any IP as well as any TCP connections.  Didn't work.

I even set it to the ports that Baggins suggested.  Didn't work...

So now I'm stumped and about to uninstall Comodo because it's so damn un user friendly.  I used to use Zonealarm, which worked really well, but the Vista version won't install on my Vista machine for some reason. I have no idea why.  I was using AVG firewall, but I thought I had the free version, instead I had the trial version.  The free version won't install on my machine now either.

Will I be safe with just the windows vista built in firewall if I uninstall Comodo?

I can't wait for Windows 7... Vista is such garbage...

Have you tried connecting to the Poser library server with IE (see some of BB's posts for the URLs) just in case some settings for that need adjusting.
