I am having trouble setting up SFTP for opencart site

Ok, I already know about these authorized keys. I can access them by looking at the metadata of the Google Cloud project itself. So I guess the question know is how do I use these authorized keys? I can't load the keys into filezilla because it does not have a private key. How do I add the private key/

Hi @chetd90,

It is not possible to generate the private key from the public key. How did you get the public keys that you have already installed on your server? Can you try to generate a new private/public SSH keys pair on your local computer and then install the public key on your server? After that, try to connect using the newly generated private key.

I generated the SSH keys I have now from PUTTYgen. There are a few keys from the past from other people worked on the project before in order to install the ssl certificate. Anyways, I was just following instructions on how to set up an SFTP connection using filezilla and PUTTYgen. However, things are just not like there supposed to. I will try to generate private/public SSH keys and then install a public keys.

Also, what is the file extension for the google ssh keys?

Hi @chetd90,

what is the file extension for the google ssh keys?

You don't need to generate any special file to install SSH keys on Google Cloud, you only need to take into account that if you are generating the keys with PuTTY, the public key is being generated in a multiline format that you will need to manually convert into a single line format as mentioned in one of my previous posts.

Also, remember that if you follow our instructions about starting an SFTP session to your server with the bitnami use, you will need to install the SSH public key in the /home/bitnami/.ssh/authorized_keys file, that is not the one you have access to from the GCP console. You will need to SSH connect to your server first, and then manually install the public key as I mentioned in another post.

Alright, I generated a new private and public key from PUTTYgen and even saved both files. I pasted the private key to the metadata of the instance and Filezilla still can connect to my instance. Do I need to format the private key in some way? Is it ok, if I message you screenshots of what I am working with here? Also, the reason I ask the question above is because I usually copy and paste the public key to notepad in order to make a file that I why I ask for the extension.

Hi @chetd90,

I have seen public key files usually named with extension .pub. Regarding the private/public keys, please note that what you have to paste in the Google console metadata is the public key, not the private one. The private one is your key to access to the server, that is why it is "private". We have a guide about how to add a new SSH key for the user Bitnami using the Google Cloud metadata. Can you check if it helps you to answer your question?

https://docs.bitnami.com/google/faq/get-started/connect-ssh/#obtain-your-ssh-credentials-from-the-gcp-marketplace

Note you will need to include the bitnami keyword at the end of your public key so it gets installed for the bitnami user. You will also find a demonstrative video in the linked guide.

Hope it helps!

Ok, I generated a public and private key using PUTTYgen. I saved both files and I pasted the content in the public key in the ssh keys of my vm instance. However, FileZilla still states that there are no supported authentication methods available after sending the public key. I guess I have to use the public key from the vm instance? However, I tried that before and filezilla said that it is open SSH key and it can't be used, I will message you the keys a little later.

gongomgra 2020-02-25 09:54:06 UTC #28

Hi @chetd90,

For security reasons, I removed your private message including your SSH keys. Please note that we can not log into your server and that we can not provide our users with one on one support via private messages.

I saved both files and I pasted the content in the public key in the ssh keys of my vm instance

How did you paste the public key to your instance, using the Google console metadata or from the SSH in-browser console?

I guess I have to use the public key from the vm instance?

You have to write the public key in the server's authorized_keys file and the use its private key with FileZilla. Remember to install the public key for the right user and login using that same user with FileZilla.

I tried that before and filezilla said that it is open SSH key and it can't be used,

Can you send us a screenshot of this error?

Apart from the above, did you check the video I mentioned in my previous post? Did you find any issue following any step in that video?

chetd90 2020-02-25 18:19:01 UTC #29

Okay, my bad about sending you the SSH keys. To answer your first question, I pasted the SSH keys in the Google console metadata. I pretty much followed the tutorial you sent me. I didn't know you can paste the SSH keys in the in browser console? What would be the commands in the console for that?

gongomgra 2020-02-26 09:49:49 UTC #30

Hi @chetd90,

Can you send us some screenshots of your process of installing the SSH public key using the Google console metadata?

I pretty much followed the tutorial you sent me

I understand you watched the video and you followed it. Am I wrong? What error are you getting after that?

I didn't know you can paste the SSH keys in the in browser console? What would be the commands in the console for that?

As I mentioned in one of my previous posts, you can run a couple of commands to manually install the SSH public key into the authorized_file of your user.

Also, you can check if the keys are properly installed running the commands below

cat /home/furiousstyles90/.ssh/authorized_keys
sudo cat /home/bitnami/.ssh/authorized_keys

Do you recognized any of the public keys shown when running the commands above? Did you add any of them using the Google Console metadata?

Thanks for the reply, I should have posted this yesterday here is the full error message:

gongomgra 2020-02-27 10:56:26 UTC #32

Hi @chetd90,

I think that error message means that your SSH public key is not properly installed on your remote server. For example, can you check that the public key of your bitnami.ppk file (usually named bitnami.pub when generated with PuTTY) is installed on your server (please, check it from the in-browser SSH console, not in the metadata) and that it has the format I mentioned in this post? Also note you can check it using my comments from the previous days.

Apart from that, can you send us a screenshot of the public key you installed? Can you also try to increase the FileZilla loglevel so we get more information about the exact error you are getting?

chetd90 2020-03-11 17:01:13 UTC #33

Do you want me to attach it to a message or do you want me to post the public key on the forum? Also, I will post the log level later.

gongomgra 2020-03-12 10:00:42 UTC #34

Hi @chetd90,

Please do not post the key here clean in the forum, simply check that its format is correct and upload a screenshot to your next post. Did you get any information from the FileZilla logs?

chetd90 2020-03-12 17:21:10 UTC #35

Ok, here are those screenshots you ask for. Can you see you can find anything.

gongomgra 2020-03-13 09:51:59 UTC #36

Hi @chetd90,

Please note this is not the private key but the public key (as it should be). Just mentioning because per the image filename.

Thanks for the screenshot. It looks like the SSH public key that you are trying to include on your server is not properly formated. I can see a couple of + characters at the beginning of some lines that I think shouldn't be there, and you are also adding the public key in a multiline format, which is wrong as stated previously. Can you remove the + chars and ensure that the public key is in a single line? Please remove the required whitespaces and new line characters too.

chetd90 2020-03-19 05:00:49 UTC #37

Ok, I will try that and let you know the results.

gongomgra 2020-03-19 10:20:53 UTC #38

Hi @chetd90,

Thanks for the info. Let us know if it worked for you.

chetd90 2020-03-24 18:03:03 UTC #39

Ok, I removed the + symbol from my public key and pasted it to the metadata of vm instance. It still does not work. Also, whenever I do add a new a new public key to the metadata I usually get a warning that says that I need to add a username and a date as in using the google ssh format. I had never had this problem before adding private and public key from Putty. Why is this happening?

gongomgra 2020-03-25 10:53:20 UTC #40

Hi @chetd90,

It is possible that the required metadata format has changed and our documentation is a bit outdated. Can you check the official docs at https://cloud.google.com/compute/docs/instances/adding-removing-ssh-keys

According to it, the format of the SSH public key string that you need to use

ssh-rsa [KEY_VALUE] [USERNAME]

Apart from that, can you connect using the in-browser SSH console as you have already done in the past and run the commands below? Please send us a screenshot so we can check the content of the authorized_file for the user bitnami.

sudo cat /home/bitnami/.ssh/authorized_keys

After that, can you try adding a new SSH key using the commands below from the SSH in-browser console?

sudo su bitnami
cd /home/bitnami
echo "SSH_PUBLIC_KEY" >> /home/bitnami/.ssh/authorized_keys

Can you also send us a screenshot of the process above?
