When I am creating AUTHENTICATION in vertica to allow users to connect from any IP its only allowing localhost connections.
CREATE AUTHENTICATION noIpRestictionNoTLS METHOD 'hash' HOST NO TLS '0.0.0.0/0';
Below is the document provided by Vertica which states to allow users to connect from any ipv4 address.
Please let me know what command we can use to create authentication to allow from any IP .

I am trying to use Plesk’s ODBC function to connect to my personal database and am unable to do so. I keep getting the error that the server cannot be found. I have allowed access to remote connections, created login credentials, and updated the firewall to allow connections through port 1433. I also tired using port forwarding through Cox Wi-Fi.
I can connect to my personal database from my own, separate server using both the name of my computer or the private IP address. However, when trying to connect from Plesk, I am unable to connect when trying the computer name, private IP, private IP with specifying the port, public IP, and public IP when specifying the port. Nothing seems to work.
Any help is greatly appreciated.
the Terminal just says:
ssh: connect to host xxx.xxx.xxx.xxx port 22: Connection timed out
Here are the firewall rules.
I can't ssh into the VM so I cant change the firewall rules on the VM
Please Help.
First, double-check your IP address: it must match your Oracle Virtual Cloud Public IP Address, assuming it is a reserved one (meaning it is a fixed one)
Second, check your local firewall: you cannot change the remote ones, but the local rules might still block your SSH traffic.
As mentioned here:
ust by opening the port through firewall and security lists will not allow new incoming connections. Ex: unless there is a service listening on port 443 (Tomcat etc), you will be unable to connect. Same with SSH daemon for port 22.
So make sure the SSH daemon is up and running.
Check also Default Security List
Unlike other security lists, the default security list comes with an initial set of stateful rules, which should in most cases be changed to only allow inbound traffic from authorized subnets relevant to the region that homes that VCN or subnet.
A list of authorized subnet ranges relevant to each region can be found here .
In particular:
Stateful ingress: Allow TCP traffic on destination port 22 (SSH) from authorized source IP addresses and any source port.
This rule makes it easy for you to create a new cloud network and public subnet, launch a Linux instance, and then immediately use SSH to connect to that instance without needing to write any security list rules yourself.
You can mount your machine drive to some other machine, edit sshd config and mount it back.
That helped me :D

I have setup a VPN and able to ping the Private IP of EC2 instance from on-premises and vice versa. However, I am unable to the ping the Private IP of DMS Replication Instance.
I have created an endpoint pointing DB in EC2. Endpoint test connection succeeds. However, endpoint test connection fails for DB in on-premises.
The EC2 and DMS Replication Instance use the same Subnet, Security Group etc., The details are given in the image below.
May I know
1) why the DMS instance is not communicating with on-premises (and vice-versa)
2) why EC2 works fine in VPN but not DMS instance?
EDIT:
Details of Security Group associated with the DMS instance:
vpc - the same default vpc used by EC2
inbound rules - all traffic, all protocol, all port range, source = 192.168.0.0/24
outbound rules - all traffic, all protocol, all port range, source = 0.0.0.0/0
Route table:
destination - 10.0.0.0/16, target = local
destination - 0.0.0.0/0, target = internet gateway
destination - 192.168.0.0/24, target = virtual private gateway used in VPN
This is the error message I get when I try to test the DMS DB endpoint connection:
Test Endpoint failed: Application-Status: 1020912, Application-Message: Failed to connect Network error has occurred, Application-Detailed-Message: RetCode: SQL_ERROR SqlState: HYT00 NativeError: 0 Message: [unixODBC][Microsoft][ODBC Driver 13 for SQL Server]Login timeout expired ODBC general error.
You might need to describe/provide your full network topology for a more precise answer, but my best guess, based on AWS' documentation on "Network Security for AWS Database Migration Service", is that you're missing source and target database configuration:
Database endpoints must include network ACLs and security group rules that allow incoming access from the replication instance. You can achieve this using the replication instance's security group, the private IP address, the public IP address, or the NAT gateway’s public address, depending on your configuration.
Also, is this EC2 you mentioned a NAT instance? Just in case:
If your network uses a VPN tunnel, the Amazon EC2 instance acting as the NAT gateway must use a security group that has rules that allow the replication instance to send traffic through it.
Currently I just create an instance on Amazon EC2 and I can ssh to the server. I installed Apache2 server and it is up but when I try to access via its public ip, then the browser come with timeout error. I have no idea related to EC2 and your idea would be worthwhile for me.
Thanks
From EC2 Docs:
If you are unable to see the Apache test page, check that the security group you are using contains a rule to allow HTTP (port 80) traffic. For information about adding an HTTP rule to your security group, see Adding Rules to a Security Group.
By default all traffics port are blocked for security reason. You need to add Inbound rules for allow http traffic(port 80)
You can add inbound rules by following these steps:
From EC2 Dashboard find "Security Groups" and then "Create Security Group"
Give a security group name and description and rules like shown in picture and then create security group.
Now you can access your ec2 public IP from anywhere.
I am having a problem with the IIS 7 on a Win 2008 server. I only want to have access to it inside my network and denied access from anyone outside the network. I had created a rule to permit access to the group of computers with the IP: 192.168.0.1 (255.255.255.0). In the IIS6 this was enougth to prevent access of any IP that don't belong to the network. Any idea of how can I block these access? Thanks!
Use IP Seсurity (IP Address and Domain restrictions role for IIS7) - it allows you to block a list of IP addresses.
Look at IP Security
The same rule should work in IIS7, you may need to install the component for IP Filtering though via the Role Manager.
In addition to the built-in request filtering, there is an addon for dynamic filtering -- http://www.iis.net/download/DynamicIPRestrictions
The rule should be: 192.168.0.0 (255.255.255.0)
to allow all clients on the 192.168.0.x network access.
First edit the configuration to deny all, then add this rule
