Hello team,

We have created a vpn tunnel (VPC) from our physical office to Amazon. The tunnel is active but I can't connect to any of my Ec2 machines using the private ip address. Is there anything additional that needs to be done in the amazon side to make this work? I'm not sure if there's a firewall or something I will need to configure as well.

Thank you!

I have not done any specific testing comparing MS Azure vs. Amazon AWS server instances but what I have noticed when I deploy instance with the same resources (e.g CPU cores and memory) on AWS it is much faster than in Azure. This is both for Linux instances and Windows.

Has anyone done some bench marking who may have insight on this?

Hi - I have been running Unifi on AWS Ubuntu instance for over a 12 months and in that time have successfully upgraded new releases. I am managing 10 networks through tyhe Unifi controller.
However, I am having a problem this time with the upgrade from 5.4.14 to 5.4.20.
I will point out to you at this stage that I am not very experienced with Ubuntu and generally get by on information ansd instructions which I find online. This is the output which I am getting from the server (using pUTTY) when I run the upgarde command:

Hello,

I currently have a few EC2 instances and a bunch of S3 buckets. I need to figure out how to download all of the logs on one of my S3 buckets and then search the logs to see what IP and access occured. is there a built in method on amazon aws to do this or what is the best easiest way to get information out of the log files?

I need to be able to search probably a couple thousand logs spanning 2016 through 2017 time period for any IP and a particular file that was accessed.

thanks,

Romtechs

Hello

I have tried a number of times to reduce the size of my EBS volume. I keep running into problems.

I am using Centos 7.3.1611 and Plesk (set up through Amazon marketplace)

I have managed to copy all the files over from the old server to the new using the instructions here (https://superuser.com/questions/1123799/how-to-decrease-size-the-ebs-root-volume-of-the-rhel-instance-in-aws) - as well as similar other guides.

The only difference is because I am using xfs instead of ext4 I was unable to do the e2label

When I attach the new volume to the instance as /dev/sda1 it does not load. I cannot connect to it using SSH and websites do not load.

I am at a loss now. I have tried so many times. I made a mistake making my initial EBS volume size way too big and it is costing me quite a bit of money every day.

I am unsure if the problem is because I am formatting my drive is XFS. This was the format of the original drive when I first set up the instance. I have not been able to find a guide that details how to shrink an EBS volume that is formatted in XFS, they are all for ext4.


If any one could provide some assistance that would be much appreciated.

Will your db performance match your db growth?
LVL 3
Will your db performance match your db growth?

In Percona’s white paper “Performance at Scale: Keeping Your Database on Its Toes,” we take a high-level approach to what you need to think about when planning for database scalability.

I am contemplating a configuration with 2 Exchange 2013 servers spanned across 2 datacenters with a stretched DAG (with DAC mode on) and the witness server sitting in AWS. My question is, will this setup allow for automatic failover of PAM and DB to the secondary Exchange server in an event of sudden outage to the primary datacenter? All the examples I found so far mentions that admin intervention is needed to start the cluster and enable the PAM role on the secondary Exchange server, so I want to get a confirmation before I venture down this rabbit hole.

Hello EE,

I have a f5 big ip virtual appliance and need to load additional network interfaces to this device . I did "attach" 2 additional network interfaces to the f5 big ip VE and it shows in the amazon console instances properly . However , accessing the  Network  ››  Interfaces : Interface List in the f5 big ip does not show the attached network interfaces even after reboot .

Hi,

I would like to know how I can send messages using an Amazon Echo to a mobile phone as well as being able to call any phone.

In relation to this:

- The phone being called can be landline or mobile
- It would be a call from an Echo to phone and not Echo to Echo
- The Echo should be able to receive message and calls as well as send
- Would it be free to send messages and make calls in this way
- Also, would anything else be needed to make this work

Thanks,
Robbie

Hi Experts,

We are running nightly onsite backups for our server (DC + File Server) using Veeam, and I want to store an offsite copy of these backups on AWS. What AWS Service should i go for? Do you have any documentation or KBs i can refer to for setting this up?

This is using Amazon t2-micro AMI 64-bit linux EC2 instance. I have a gmail email address, thinking of setting up a mail client, with correct credentials so as email can be sending out from this server. I saw a Sendmail daemon is running. I am thinking of sending a tripwire report to my gmail email address, with the cron job command as shown:

/usr/sbin/tripwire -m c | mail -s "Tripwire Report from HOST" abc@gmail.com

I heard that sendmail client is pretty difficult to setup. How about other mail client, such as postfix, and so on.

Thanks in advance.

Hello EE,

I have an f5 big ip appliance up and running , however I wish to have 2 interfaces configured . One interface to sit 'out front' of our dmz firewall , and a second network interface to reside 'inside' on the 'lan' to load balance tcp traffic and run irules .

Can someone provide direction please on this matter.

Experts,

We are trying to bring up a postfix mail server on an AWS EC2 instance. We have gone through SES but we need to manage our mail server rather than AWS managing it for us.

We already have a domain linux.com. The next step would be to bring up a EC2 instance and install Postfix on it. I would assume we need an Elastic IP assigned and then map a DNS mail.linux.com to it so that is is resolvable. I'm next assuming we need to assign an MX record for mail.linux.com. Would this generally work if you send email to someone@linux.com or are there additional steps like assigning SPF records and DMARC.

Hi,
I'm trying to setup a new webrtc instance behind the firewall where tcp 80 and 443 ports are only available.
All is fine as long as udp ports are enabled. Once I block udp, I can't establish a client connection.
The stun/turn server has been setup however connections are not redirected from webrtc.

RTCMultiConnection.js config:

var IceServersHandler = (function() {
        function getIceServers(connection) {
            var iceServers = [];
iceServers.push(getTURNObj('turn:my.domain.com:443?transport=tcp', 'user', 'pass'));
            if (window.RMCExternalIceServers) {
                iceServers = iceServers.concat(getExtenralIceFormatted());
            } else if (typeof window.getExternalIceServers !== 'undefined' && window.getExternalIceServers == true) {
                connection.iceServers = iceServers;
                window.iceServersLoadCallback = function() {
                    connection.iceServers = connection.iceServers.concat(getExtenralIceFormatted());
                };
            }

            return iceServers;
        }

        return {
            getIceServers: getIceServers
        };
    })();

turnserver.conf config

listening-port=80
tls-listening-port=443
listening-ip=10.10.10.10
relay-ip=1.1.1.1
external-ip=1.1.1.1/10.10.10.10

user=user:pass
realm=domain.com
no-udp
no-dtls

All is running in AWS cloud.

I have a FIX engine running in the cloud and I'm entertaining the idea of streaming FIX messages over websockets vs aws SNS.  Does anyone know pros'cons for either or at least some concrete resource to be able to compare the 2?

I built lightweight clients for both and both seem to be able to be tuned for high usage as well as low usage, so its just matter of price seems like.  Need help deciding.

Simply put.. I connected to a free micro instance of a postgres DB I created on AWS RDS.

It worked fine. I set up a database and a couple tables on it.

Now that I'm trying to connect to it from my app.. it's just timing out.

AND.. I can no longer connect to it from PSequel or.. anything. It just keeps timing out.

I'm not even sure what more detailed questions to ask or what to direction to poke in on this one.

Hi I have developed a powershell script to logrotate on aws s3. The procedure is that  through script I create archive using 7zip and then use aws put-object. But the script fails to create archive in first step and cites it cannot read archive.

The second approach I did was used compress-archive to create archive and it worked successfully to create archive. But when I download the archive from s3 manually I find that sub-directory files are all present in root folder and all files named as filepaths. This happens as compress-archive fails to send metadata of archive.

Hi,
I am setting up a SQL 2012 failover cluster in AWS, My two sql nodes are in different availability zones (2 x Subnets) 10.10.1.0/24 (Zone A) and 10.10.2.0/24 (Zone B). I have configured windows failover cluster / sql cluster and am able to failover between the two servers. There are two DNS entries for the sql cluster name,

AWS-SQL-CLUS - 10.10.1.20
AWS-SQL-CLUS - 10.10.2.20

Currently the host in Zone A is online and servers in that subnet can connect to the instance but servers in Zone B are trying to connect to AWS-SQL-CLUS - 10.10.2.20 which is offline.... how do i get the servers in other subnet to resolve the DNS entry of the online server ??

I have a public nat instance and private instance with only private ip. Without iptables in nat instance , private instance is getting internet. But after adding iptable rules in nat instance, private instance is not getting internet. I added iptable rules with output drop,input drop ,forward drop chain. After adding this rule nat is not working.

Do I need to add any pre routing or post routing rule to my iptable rule list.
