@chrisadams27 2 года назад

This is great, however you haven't covered much in terms of how the bastion host could be exploited and used to hack the private instance.

@rupeshpatil5279 Год назад

I am getting below exception even agent forwarding is enabled when trying to connect private instance from public Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

@vikashbucha 2 года назад

This is useful. Now how do I scp files from local to target machine with the bastion in between.

@rayhanalam3101 2 года назад

hi i am getting error when going into my private instance using agent forwarding from my public instance. i have given the keypair file correct permissions chmod 400, can you please help Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

@nainabhartia9260 Год назад

where are you running these commands ssh-agent? Is it windows powershell?

@sanjeevvasisht8395 4 дня назад

@MalshikaPeiris6327 10 месяцев назад

I can't connet make internet connection of the private subnet.can you help me?can you tell me how to connect private subnet manually like public subnet(not using commands in Aws console)

@siddhantsingh7724 Год назад

what if we use diff keys for instances how to configure then? I have single bastion and multiple private instances with diff type of keys ...for now i am able to connect with pageant and agent forwarding but it is to much is there a way i can configure ssh in bastion ??

@azzamqazi3766 2 года назад

How about if we want to host a web application in private tier and give access to customers to access it, how would that be possible with the bastion server?

@aulderyan 2 года назад

This is not a well architected approach. You would never give a customer access to a bastion host. You should create a web server in a public subnet and keep the app server in a private subnet and limit traffic between the two using Security groups and NACLs.
