I don't know what's wrong with it. Here is a screenshot.
(first image is what i've done in terminal to log in my EC2 server
second image is what i've set in "System preference --> sharing --> remote login)
Yosemite is my OS. Please help me,
Assuming that you have the right key file, you could be running into some security settings issues. Check your security group and make sure that the server is accepting connections on port 22 from all addresses. Also, I generally use the IP address when SSHing into an EC2 box instead of a url, as it is much shorter and more concise. Also, make sure that your server is running Ubuntu. I know that different OS's on EC2 use different default usernames.
Your default username can be found at this page:
http://alestic.com/2014/01/ec2-ssh-username
In the end, your ssh command should be something like
ssh -i otkey.pem [username for your os]#[ip of your box]
Hope this helps!
You've got the right command for an ubuntu server. Check to make sure that security groups are configured and that you don't have Network Access Control Lists configured on your VPC. The configuration you made to the settings of your laptop are to open it up for people to log into your laptop, they don't do anything to facilitate you connecting out.

I am installing VMware vSphre ESXi 7.0.2. But I cannot use web client (http://<ip_address>/ui)
When installed first time, I can connect with https://<IP_address> (It will be redirect to https://<IP_address>/ui ) and can create VM. But I found I cannot use some SDD/HDD. So I have re-installed ESXi after created the RAID partitions.
Re-Install was look OK, and I can see DCUI and set IP, DNS etc... After all set, I've tried to use https://<IP_address>. But it was timed out. (I have checked several things, then I found the ping does not work.)
I restarted the server then ping is OK. But when I try to connect with https://<IP_address> then the ping became "Destination net unreachable". (I have confirmed it with "-t" option.)
I thought it is firewall settings. So, I changed "--default-action" and "--enabled" but it still not working. Just in case, I have stop to use RAID disks and re-install it again (it is same as first installation), but it was same results.
There's likely still a networking-related misconfiguration. Use DCUI to verify IP/subnet mask/gateway/VLAN tag (if necessary) and that the appropriate NIC has been configured.
If those are set correctly, the DCUI also has some built-in testing options which allows you to do some outbound ping testing. By default it will check 3 hosts, including the gateway and usually two DNS names, but those can be changed to other options.
I have been trying to setup Docker in Windows Server 2016 in an AWS instance to run an IIS program.
From this question,
Cannot access an IIS container from browser - Docker, IIS has been setup inside a container and it is accessible from the host without port mapping.
However, if I want to allow other users from the Internet/Intranet to access the website, after Google-ing it, I guess we do need port mapping...
The error I have encountered in port mapping is given in the above question so... I guess using nat is not the correct option. Therefore, my team and I tried to create another network (custom/bridge) following instructions from
https://docs.docker.com/v17.09/engine/userguide/networking/#user-defined-networks
However, we cannot create a network as follows:
; Googled answer:
https://github.com/docker/for-win/issues/1960
My team guessed maybe its because AWS blocked that option, if anyone can confirm me, please do.
Another thing that I notice is: when we create an ECS instance in AWS,
So... only default = NAT network mode is accepted in Windows server?
Our objective: put the container hosted IIS application to Internet/Intranet in Windows Server 2016...
If anyone has any suggestion/advice, please tell me, many thanks.
I wrote the following command in CMD:
ssh ec2-user#01.01.001.001 -i node.pem
I receive this error:
ssh_exchange_identification: read: Connection reset
I am hosting a website on my Windows Laptop using an Amazon EC2 instance.
How can I get rid of this error?
I can't comment your question due to my low rep to have some further details so I give this a try.
There could be a lot of reasons for this to happen:
the IP is wrong; I suppose that the one you wrote is a fake one. If
it's not, go to your EC2 panel to check the correct one;
the username is wrong; on ubuntu servers you should use ssh ubuntu#ip-address
the server is not reachable for some reason: bad security group
configuration (is the port 22 open?), firewall on your
network/computer...
You can add the flag -vvv to your ssh command to have a very verbose log of your connection so it will we easier to debug.
This might seem like a duplicate question but it is not. I tried to go through similar questions but I couldn't find a fix for my problem. Here is my problem:
I need to set up an ftp connection on company servers.
I can easily connect to ftp server from fileZilla on my PC but when I try it over one of the server machines to the file server all I see is the following:
Response: fzSftp started
Command: open "*****#***.***.***.**" **
Error: Connection timed out
Error: Could not connect to server
Status: Waiting to retry...
Status: Connecting to ***.***.***.**...
Response: fzSftp started
Command: open "*****#***.***.***.**" **
Error: Connection timed out
Error: Could not connect to server
I googled the "Connection timed out"
error and I realized that the first place to check is firewall or router setting. these are outsourced to another company and they say that the issue is solved and it should work fine. I don't know where to look at.
I've had lots of issues with Filezilla. You may try another software first to see if Filezilla itself is the issue.
If you're on Windows, I highly suggest the open source project WinSCP (https://winscp.net/eng/download.php). For Mac, Cyberduck (https://cyberduck.io/?l=en) is solid (and free), though you may prefer Transmit.
I was having this problem after upgrading Filezilla. I downgraded it to a previous version and it worked like charm. I came across this ticket thread and it was absolutely helpful : Filezilla Support Ticket
Check your security group rules. You need a security group rule that allows inbound traffic from your public IP address(Google: What is my ip?) on the proper port.
Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.
In the navigation pane, choose Instances, and then select your instance.
In the Description tab, next to Security groups, choose view rules to display the list of rules that are in effect.
For Linux instances: Verify that there is a rule that allows traffic from your computer(public ip) to port 22 (SSH).
For Windows instances: Verify that there is a rule that allows traffic from your computer(public ip) to port 3389 (RDP).

I need to set up an ftp connection on company servers. I can easily connect to ftp server from fileZilla on my PC but when I try it over one of the server machines to the file server all I see is the following:
<failure to connect code>
Please note that public IP and internel IPs will be a different address; such as 123.456.675.574 for the public but internal to the server network it will be something more like 192.168.10.574 .
This is why you can easily connect from your PC because it uses the public IP address but from the internal IP network of the company servers that address will not be valid, and the internal one would need to be used instead.
Try this, 200 is just an example, just increase it and try.
Edit --> Settings --> Connection --> Timeout in seconds = 200
I have RAILO (Railo 3.1.2.001 final) installed on an AMAZON EC2 instance and everything seems to be working fine for the tests I have done. I can connect to mySQL and simple commands work. The applications I am planning to run on it make extensive use of CFFTP to pull files in from clients and process them. The OPEN command works fine and I get a succeeded in Active and Passive mode, but when I try to do anything (check for a file, put a file, download) I get : 500 Illegal PORT command.
My thought here is the AMAZON firewall is blocking some ports and something needs to be setup for this to function.
Anyone have any experience with this and can point me in the correct direction?
Thanks in advance,
Jeff
do you connect from outside amazon to the instance ? if you do check the security group and allow the ip/port for your application.
