calibre content server problem
I can access the calibre content server just fine from Stanza on my iPod, but for whatever reason I can't seem to access it anywhere else, including from the web browser of the computer from where calibre is installed, if I use my public IP address.
I am using an Airport router which I have set up to forward port 8080. But if I type in my public IP with the port in my web browser, it says unavailable. I am also now trying to access the content server from Aldiko. I added the content server as a catalog in Aldiko, but all attempts to access it result in a timeout. I'm assuming that somehow my airport router is causing the problem here, but I don't know what more I can do but forward the port? Any ideas? Thanks in advance. |

Yes, and I also tried using another port (8787). But I remain unable to connect, except through my iPod. "Test server" within calibre also works.
(Also tried turning the firewall completely off--no difference). Last edited by sovre; 02-16-2012 at 12:31 AM. |

I'm getting conflicting info about NAT loopback support on the Apple Airport router. One site says it does, another says it doesn't. I don't have an Airport router so I can't check the configuration to see if it's possible, but if you can't make it work then the easiest option is to refer to the internal IP when you're inside your network and the external IP when you're outside your network. Technical alternatives: you could see if the Airport can flash alternate firmware like DD-WRT or Tomato, or you can do what I do and run a linux box as a router and either setup NAT loopback through iptables rules or use Apache as a reverse proxy for a dynamic dns hostname. I can go into more detail if needed. Edit: The reason Stanza works is because it's finding the local machine via UPnP discovery (Bonjour). It's not going to the external IP. |

Thanks for your reply, toddos.
Yes I am using my external IP. And I am guessing that the calibre library "server test" is using my internal IP address, and that is why it is connecting. You say this is probably the reason my iPod is connecting as well. But here's the problem: if I input that same address into Opera Mobile, to try to connect to my calibre server through my Asus Transformer, I immediately get the message "could not connect to remote server." So I cannot seem to connect from this device, using either the internal or external IP. (I removed the server password, because there is a note in calibre that the password is incompatible with android, but still no difference.) Last edited by sovre; 02-16-2012 at 04:18 PM. |

Without actually being on your internal network, I can't really do much more. At this point, it'd be interesting to see the results of systematically testing with multiple browsers (we can ignore Stanza for now because of how it's finding the server): From inside your home network
From outside your home network (from work, a friend's house, the local starbucks/McDonald's/library/where public wifi is available, through your phone's cell phone connection instead of wifi, etc) If this is a NAT loopback problem, I'd expect 1, 3, and 6 to fail, 2, 4, and 5 to succeed (5 is iffy). And the external network test should succeed as well. If 2 or 4 fail while inside your network, something else is broken. |

2 and 4 fail. can't figure it out.
I don't think stanza can be accessing my library through the internal ip, because I can't access it through the internal ip using the safari web browser on my iPod or the web browser on my laptop. Do you know what method Stanza uses to get access? It seems like this would be the most probable way to solve my problem, since Stanza alone can access the library. Stanza seems to be programmed to do whatever it is Calibre server likes most! Does it use a name to gain access instead of an IP address? I don't really know how this technical stuff works. I notice the Airport router does have an option for setting a NAT address though. Could doing this be helpful? |

If access the internal ip address from a machine on your internal network doesn't work yet the server is definitely running, either you've got the wrong internal ip address or the wrong port. |

thanks, toddos.
your last message helped me solve it. I was using the IP address connected to by calibre's "server test," assuming it was the internal IP. Turns out it is not. Not sure what that address is! I found that the IP listed in internet config was different and changed to that one, and now I can connect. Problem solved. |

Help needed with connection server.
I am having this same problem. But if I go to ipcong /all I have the following IPs displayed: Link-local IPv6 Address, DHCP Gateway, and DHCP Server. I have tried all of these on my Galaxy tablet to try to connect to my content server and none of these work. I am running Vista at the moment on my desktop. Calibre says my content server is running and iut states it is running on 0.0.0.0:8080. What am I doing wrong?

Have you checked the firewall on your PC to make sure that the calibre server is allowed to accept connections from outside the PC? The default would probably be that it cannot.
