A user (RT-#6268) wants to know if it is possible to associate an AWS elastic IP with a Tor Cloud instance.
I think that I'm the user this is referencing. I've copied below my original query to provide more texture, though it isn't structured well as a feature request per se.
I have an old 10.04 Tor Cloud instance running with pretty much everything outdated, and my understanding is that I need to start a new instance in order to get all the necessary upgrades and have Obfsproxy working and all of that.
One thing that bothered me about this is the loss of the IP address, since my instance has been around for quite a while now and gets a fair amount of traffic.
It occurred to me that in order to prevent an IP switch in the future, I could generate an Elastic IP and associate it with any instance that I use now or in the future. I had a few concerns about this, though, and I know next to nothing about IP infrastructure.
If I associate the Elastic IP with my instance, does Amazon change any setting on the instance itself that the Tor software would recognize? I.e., would the bridge automatically pull down the Elastic IP address from a network setting in the box and report it to the big bridges directory, or would it still continue to report a different, instance-specific IP that would be lost with each reboot or upon termination?
Assuming the answer to (1) is "no, it doesn't do it automatically" then I understand from IRC that that the torrc would need to be edited so that "OutboundBindAddress and "Address" are set to the Elastic IP.
(a) Would I need to add these as text in the torrc file and re-upload it via sftp, or is there an easy way to set them through tor-arm in ssh that maybe I'm missing?
(b) Are there any other settings that would need to be changed?
(c) Would these settings generally persist through updates and reboots, provided it's still the same instance? When I upgrade my own PC Vidalia client, I manually deselect torrc while going through the overwrite prompts in Windows rather than saying "Yes to all."
(d) Are there any other potential complications that I should be aware of (mismatch with local IP that tor might be using for something, IPv6 teething issues with manually binding addresses, etc.)?
Tor cloud is discontinued. This is a very specific bug to keep around. If there is a revival, then this issue could be looked at when whatever that looks like emerges.
