For the Ledger Chrome app to work, what IP addresses/ports do I need to open for basic functionality (sync/spend/confirm on mobile device)

You only need to open port 443 on *.ledgerwallet.com

I looked at the traffic generated a while back. I thought chain.com was accessed by the app also?

The application had a websocket open to Chain in the past, now we are using our own service.

Thank you!

I have another question about security:

I tried out Mycellium with Ledger for the first time yesterday. When using Mycellium, even though the Security Card is required to spend, the app is able to display the HW.1's complete list of mnemonics without the Security Card.  Does this mean that someone in possession of just the Ledger Nano/HW.1 and the 4-digit pin can reconstruct the bip32 seed and spend without the security card?

No, the app is probably displaying the mnemonic from your main account - not from the Ledger one. There is no way to recover the mnemonic from the chip, for security reasons obviously  Grin

Oh! you're right. The mnemonics were completely different. I guess the Mycellium interface takes a little getting used to.  

Are there plans to have mycellium support the secure screen verification, or a complete Ledger wallet app for Android that does?

It will be possible to do that with specific hardware - if there is a Trusted Execution Environment available with direct access to the UI, we can use that to prompt for a secure confirmation, or with our next wallets, but not with the Nano - otherwise we'd have to use another phone as a second factor.

How do I empty a wallet without leaving any dust satoshi ?

we don't have an option to do that automatically yet, you have to substract the suggested fee value from your total amount.

Have been using a duo hw.1 setup (one as a backup) for well over a year and find it an excellent and inexpensive hw solution especially when used with a smartphone as a second factor for improved convenience when spending. Have started looking into using copay and their multi sig support which also supports ledger hw.1/nano as a co-signer. The question I have is can I continue to use my hw.1 as a dedicated hardware wallet, as well as, have it function as a co-signer for the copay wallet? Or does this require or on security grounds a separate ledger hw?

Yes, you can do that if it was properly initialized with the "allow multisig without confirmation" flag - it might not be if you were one of our first users. In this case, you'd just need to reset the HW.1 by entering a wrong PIN 3 times, and restore it with the latest Chrome application. But you can test it with Copay first. If it works, you're good to go.

I don't recall seeing that option when I originally set it up. Good to know it should work so I'll give both suggestions a go now. Thanks

I just bought a HW.1, and i wanted to quickly review the process and ask some extra questions.

Process:
  • finding the website and the product: Really easy
  • ordering and paying: since i expect BTC to rise pretty soon,so i didn't want to spend any BTC, so i was happy to being offered the option to pay with Paypal
  • shipping, handling, packaging: I ordered on the 21st, chose the slow option, was supprised when i found the package in my letterbox on the 25th... WOW  Grin. Also: i was expecting a small letter containing a small piece of plastic, but i received a professionally wrapped big envelop, containing a sealed cardboard box... Shipping and handling was top-notch
  • price/quality ratio: the stick itself looks a bit flimsy, but when you hold it, you can actually feal it reasonably durable. I don't think you'll find any HW wallet with such a good price/quality ratio
  • initialising my ledger: i used the iso-image i found here https://www.ledgerwallet.com/files/ledger-secure-starter.iso on an usb-stick in order to initialise everything... went perfectly
  • setting up my system: on my workpc (windows 7), it went like a breeze, on my homePC (openSuse), i needed to do this: http://support.ledgerwallet.com/knowledge_base/topics/ledger-wallet-is-not-recognized-on-linux

Here are my questions/remarks, maybe some of them were already answered, i didn't do the effort of plowing trough 19 pages of replys... i'm very sorry  Embarrassed
 
  • at the moment, the ledger wallet is basically a chrome plugin... Will this always stay like this?
  • maybe it's a good idear to put the linux tutorial on how to get the wallet working on a more prominent spot
  • will there be an option to sign messages in the near future? I think this would be a great addition, since that way i could get rid of my electrum wallet
  • speaking of electrum: would it be possible to get a newbie-friendly version of the installation manual for electrum? I found a tutorial, but it was so long i didn't bother following it
  • a new address is being generated for each transaction (perfect), but at the moment, i'm transferring funds to my ledger with very low fees (i don't care if it takes days, even weeks before it's confirmed): i don't see unconfirmed transactions to the newly generated address, while in fact, there is an unconfirmed transaction viewable on blockchain.info (i'm not willing to share the tx because of privacy)... is this a feature or a bug?

Thanks for the review, on to the questions

  • at the moment, the ledger wallet is basically a chrome plugin... Will this always stay like this?

On desktop yes, we don't plan to make it a standalone application (or maybe a standalone Electron application at some point, which doesn't change much)

  • maybe it's a good idear to put the linux tutorial on how to get the wallet working on a more prominent spot

yes, we'll think about it

  • will there be an option to sign messages in the near future? I think this would be a great addition, since that way i could get rid of my electrum wallet

this will be available in the next firmware update, when paired to a smartphone.

  • speaking of electrum: would it be possible to get a newbie-friendly version of the installation manual for electrum? I found a tutorial, but it was so long i didn't bother following it

yes, this is long overdue, but we didn't get an opportunity to write it yet.

  • a new address is being generated for each transaction (perfect), but at the moment, i'm transferring funds to my ledger with very low fees (i don't care if it takes days, even weeks before it's confirmed): i don't see unconfirmed transactions to the newly generated address, while in fact, there is an unconfirmed transaction viewable on blockchain.info (i'm not willing to share the tx because of privacy)... is this a feature or a bug?

it should be displayed, you can send your logs to support@ledgerwallet.com so the wallet team can have a look if it doesn't appear.

It did appear as soon as the transaction was confirmed... As long as the transaction wasn't confirmed, it didn't show up in the wallet's transaction list.
Can you tell me where i can find the standard log directory on windows?

You should get them when clicking on Settings / Tools / Export Logs, but since it appeared, it might just have been a temporary mempool glitch, as we're still tweaking servers a bit.

I'll let you know if it ever happens again  Smiley
Great product, even better to see you're active on the forum, and responding to questions your users have: +1 Grin

I have an HW.1 that is no longer recognized by the computer. Something must have gone wrong during initialization with Electrum.

I think I had unplugged it as instructed and was trying to display the seed in my text editor on an offline computer, but nothing was ever displayed.  Now it is not recognized in ANY computer. I've tried the chrome app, the ledger starter iso, and https://fup.hardwarewallet.com/ledger/, and none of them are aware that I have plugged the device in.  My other two HW.1 are detected normally.

Is there any way to recover it?  Thanks

What firmware version are/were you running on the HW-1

Can you show the USB bus report for the HW-1

Ledger Wallet:
  Product ID HuhHuh

Power cycle your HW-1 and see if the Product ID changes.
