Can't clone AUR repository. Dumb ssh sending all keyfiles.

Good afternoon,

I found a cool project I would want to use (kyua), which sadly, is not packaged for Arch.
I wrote PKGBUILD for it, and also for one dependency of this program (lutok). Since it's very
useful I decided to submit this package to AUR.

I have already done this before. However, don't remember how exactly. The problem
was that I was not able to clone the repository. git refused with:

Klonowanie do „lutok”...  // Cloning to "lutok" ...
ssh: connect to host aur.archlinux.org port 22: Network is unreachable
fatal: Nie można czytać ze zdalnego repozytorium. // fatal: Could not read from remote repository

Upewnij się, że masz odpowiednie prawa dostępu // Make sure, you have right access permissions
i że repozytorium istnieje. // and repository exists.

After running "ssh -vvv aur.archlinux.org" command, I realized, that ssh is not trying
to use "~/.ssh/aur". It's trying to access non-existing id_rsa, id_ecdsa, ...

Even though I used "IdentitiesOnly=yes" option in my configuration:

Host aur
	HostName aur.archlinux.org
        User aur
	IdentitiesOnly=yes
	IdentityFile /home/notroot/.ssh/aur

1. What's your ssh configuration for AUR?
2. I tried different configurations a lot of times and it looks like I got banned (ping returns "Destination Port Unreachable"). What should I do to have my ban removed.

Re: Can't clone AUR repository. Dumb ssh sending all keyfiles.

1. What's your ssh configuration for AUR?

Host aur
HostName aur.archlinux.org
User aur
IdentityFile ...
PubkeyAuthentication yes
PasswordAuthentication no
PreferredAuthentications publickey
Compression yes
Protocol 2

2. I tried different configurations a lot of times and it looks like I got banned (ping returns "Destination Port Unreachable"). What should I do to have my ban removed.

Your account has not been suspended.

ssh: connect to host aur.archlinux.org port 22: Network is unreachable

Are you able to connect to other servers on port 22? Your ISP may be blocking the port.

Re: Can't clone AUR repository. Dumb ssh sending all keyfiles.

first off, LC_ALL=C, and post full, untranslated logs.

Now if you've had multiple failures, yes, you're going to have a temporary ban. Should be 24 hours, IIRC. You can try #archlinux-devops on libera if you want it done manually sooner.

As for the config, https://wiki.archlinux.org/title/AUR_su … entication

Yes.

This config did not work for me, I added IdentitiesOnly=yes option, it still did not work.

Edit:
I have many keys in ~/.ssh/ directory. I always need to add IdentitiesOnly=yes, otherwise ssh will send all found keys in random order.

Re: Can't clone AUR repository. Dumb ssh sending all keyfiles.

I solved this problem. It looks like ssh is not recognizing aur.archlinux.org host if there is entry for it with another name.

I had to change:

Host aur

to

Host aur.archlinux.org

in my config file.
