I was wondering if Amazon Web Services disallows outbound SSH connections from public facing EC2 instances? I have an SSH Bastion on a public subnet with an Elastic IP setup to where I can can successfully tunnel connections into my VPCs but when I create a Security Group rule to allow outbound connections to a remote server and try to make a connection I get:

ssh: Connection timed out

I've done some searching, and found this question unanswered:

Edit: I can SSH from the SSH-Bastion but ONLY to other EC2 instances that belong to me. Connecting to an external server not on AWS is currently not working for me.

Edit2: I can also make outbound connections to the internet through an Internet Gateway. Running works

curl www.google.com 
telnet www.google.com 80

The outbound security rules for the bastion look like this:

22 (SSH)    [internal AWS Private subnet range]
22 (SSH)    [external linode ip]
80 (HTTP)   0.0.0.0/0
443 (HTTPS) 0.0.0.0/0

I have an Amazon VPC setup with a private subnet containing 2 instances. One of them has redis running on it, the other instance I want to use to connect to the redis server. I have the redis instance listening on port 6123. When I connect locally on the Redis instance, everything works, but when I try to connect from the other instance on the subnet I get:

Connection refused - Unable to connect to Redis

I setup two separate VPC security groups, one for the redis server, allowing inbound connections on port 6123 using the other instance's security group as the source. Likewise, I added a rule to the security group for the other instance to allow outbound traffic on port 6123 to the redis-instance (using the redis instance's security group as the destination).

Is there something I'm forgetting here? Another rule that I have to add? Or a special route I have to setup?

Thanks for any help/direction, Tom

I was wondering when connecting to a git repository, does the git+ssh protocol use the same port number as just using the git protocol. For example:

git://example.com/git/helloworld

git+ssh://[email protected]/git/helloworld

I am trying to push to a remote repository that has port forwarding setup on only the git protocol port number (9418) using EGit. When I try and use the git+ssh, EGit tells me

git+ssh://.... connection is closed by foreign host

Thanks,

I setup a Turnkey Trac virtual machine and am trying to set up the LdapPlugin to use use authentication through a local Active Directory. I tried using

easy_install http://trac-hacks.org/svn/ldapplugin/

to install it and it claimed to have completed, however when I go to the Admin page and go to plugins, it is not listed. I have never setup a Turnkey server like this before and was wondering in which directory the Trac plugins are located on the Turnkey-linux machine?

Thanks,

Tomek
