Sip failed to authenticate

While putting in a New Exchange server today, I test moved a mailbox to this new site, and could not get mail to flow to the Exchange server at the clients main site.

Either there are no alternative hosts, or delivery failed to all alternative hosts. Mail flowed from the main site to this new site, and internal mail at the new site was fine, but any mail destined for the main site, or going external because the main site has the only server that can use the Exchange organization send connector would fail with this error. I did a lot of trawling to try and find the answer to this, and discovered lots of reasons for this to happen, so rather than just posting what fixed mine, from the most popular to the most obscure try these in order, and attempt to send mail after each step.

If you have Cisco PIX Firewalls between these two mail servers running version 6 or earlier make sure smtp fixup is disabled. If you have Cisco ASA Firewalls between these two mail servers, then remove esmtp from the default inspection map.

At this point I admitted defeat and picked up the phone and called Microsoft. One of their support engineers looked at the connectors and settings, and tested the DNS, had me create a new connector, still mail refused to flow.

He did however get me pointed in the right direction. When attempting to Telnet to the Exchange server on the main site this is what we saw. I put all the firewalls in, so I know how they are configured, and I know this client has a CSC module in the ASA at the mail site, I managed to get the output above by rebooting that module, as soon as it was back online we reverted to the short list again.

Also while the CSC was rebooting all the mails stuck on the outbound queue cleared. Note : Your class-maps, and access-lists may have different names but this should point you in the right direction.

As important as these three security techniques are, there is still one more aspect that must be addressed. How do you guarantee that the sender of a SIP message is who he or she claims to be? This is where SIP authentication comes in. This means that anyone receiving an INVITE message can force the sender to prove his or her identity before the message is processed.

In fact, an Avaya system challenges every single SIP message every time one is sent. This four-step process ensures that only authenticated messages are sent to SIP applications for processing.

There are two different forms of the 4xx challenge response and although they essentially perform the same task, they are sent from different entity types in response to different SIP messages. These responses are:. Here is the entire call flow:. Take a look at the first six messages and you will see authentication in action.

This header contains the data that must be used by UAC to encrypt his or her credentials. Take a look at the Proxy-Authenticate header and you will see a Nonce parameter. Nonce stands for Number Once and is an arbitrary number used only once in a cryptographic communication. The recipient of a Nonce will use it to encrypt his or her credentials. Number once refers to the fact that encryption with this Nonce can only be done one time.

It becomes stale and useless immediately after its first use. Notice how Proxy-Authentication repeats much of what was in Proxy-Authenticate. I mentioned that there are two 4xx challenge responses. RFC states the following about the two headers:.The following information can help you troubleshoot issues with connecting to your instance. We recommend that you begin troubleshooting by checking some common causes for issues connecting to your instance.

You can connect to your instance using the user name for your user account or the default user name for the AMI that you used to launch your instance. For more information about how to create a user account, see Managing user accounts on your Amazon Linux instance. Get the default user name for the AMI that you used to launch your instance:.

Asterisk Forums

For a Fedora AMI, the user name is ec2-user or fedora. Otherwise, if ec2-user and root don't work, check with the AMI provider. Make sure your security group rules allow inbound traffic from your public IPv4 address on the proper port.

For steps to verify, see Error connecting to your instance: Connection timed out. After you launch an instance, it can take a few minutes for the instance to be ready so that you can connect to it. Check your instance to make sure it is running and has passed its status checks. In the navigation pane, choose Instancesand then select your instance. For more information, see General prerequisites for connecting to your instance. Check your security group rules. You need a security group rule that allows inbound traffic from your public IPv4 address on the proper port.

In the Description tab at the bottom of the console page, next to Security groupsselect view inbound rules to display the list of rules that are in effect for the selected instance. For Linux instances: When you select view inbound rulesa window will appear that displays the port s to which traffic is allowed. Verify that there is a rule that allows traffic from your computer to port 22 SSH.

For Windows instances: When you select view inbound rulesa window will appear that displays the port s to which traffic is allowed. Verify that there is a rule that allows traffic from your computer to port RDP.

Each time you restart your instance, a new IP address and host name will be assigned. If your security group has a rule that allows inbound traffic from a single IP address, this address may not be static if your computer is on a corporate network or if you are connecting through an internet service provider ISP. Instead, specify the range of IP addresses used by client computers.

If your security group does not have a rule that allows inbound traffic as described in the previous step, add a rule to your security group.

Check the route table for the subnet. In the navigation pane, choose Internet Gateways. Verify that there is an internet gateway attached to your VPC. Otherwise, choose Create Internet Gateway to create an internet gateway. In the navigation pane, choose Subnetsand then select your subnet. On the Route Table tab, verify that there is a route with 0. Otherwise, do the following:.

Choose the ID of the route table rtb- xxxxxxxx to navigate to the route table.

On the Routes tab, choose Edit routes. Choose Add routeuse 0. Check the network access control list ACL for the subnet. The network ACLs must allow inbound and outbound traffic from your local IP address on the proper port. The default network ACL allows all inbound and outbound traffic. In the navigation pane, choose Subnets and select your subnet.These issues are most likely to be seen in an environment with a proxy server. The installation wizard and the sync engine proper require machine.

NET applications. In this article, we show how Fabrikam connects to Azure AD through its proxy. The proxy server is named fabrikamproxy and is using port First we need to make sure machine. In some non-Microsoft blogs, it is documented that changes should be made to miiserver. However, this file is overwritten on every upgrade so even if it works during initial install, the system stops working on first upgrade. For that reason, the recommendation is to update machine. The proxy server must also have the required URLs opened.

This list does not include any optional features, such as password writeback, or Azure AD Connect Health. It is documented here to help in troubleshooting for the initial configuration. The installation wizard is using two different security contexts.

On the page Connect to Azure ADit is using the currently signed in user. On the page Configureit is changing to the account running the service for the sync engine. If there is an issue, it appears most likely already at the Connect to Azure AD page in the wizard since the proxy configuration is global. This error appears when the wizard itself cannot reach the proxy. If you use a Microsoft account rather than a school or organization account, you see a generic error.

If the installation wizard is successful in connecting to Azure AD, but the password itself cannot be verified you see this error:. To verify if the Azure AD Connect server has actual connectivity with the Proxy and Internet, use some PowerShell to see if the proxy is allowing web requests or not.

PowerShell uses the configuration in machine. If the proxy is correctly configured, you should get a success status:. If you receive Unable to connect to the remote serverthen PowerShell is trying to make a direct call without using the proxy or DNS is not correctly configured.

Make sure the machine. If the proxy is not correctly configured, you get an error:. This can happen especially if there are a number of group objects with large group memberships included in the same export request. Ensure the Proxy idle timeout is configured to be greater than 5 minutes.

If you have followed all these preceding steps and still cannot connect, you might at this point start looking at network logs. This section is documenting a normal and successful connectivity pattern. It is also listing common red herrings that can be ignored when you are reading the network logs. Here is a dump from an actual proxy log and the installation wizard page from where it was taken duplicate entries to the same endpoint have been removed. This section can be used as a reference for your own proxy and network logs.

The actual endpoints might be different in your environment in particular those URLs in italic.

If everything used to work fine and stopped working all of a sudden, there can be many reasons for this. For example, an auto update could have been sent to your router or the Kindle Fire. Or, too many devices or routers on the same channel.

Having a problem with the Kindle Fire WiFi authentication can be very frustrating. If your Kindle Fire is still failing to authenticate and you continue to struggle with the Kindle Fire WiFi authentication problemyour best bet is to contact Amazon customer service.

I have checked your newswirl. But you can fix this issue fast. Thank You. I tried for two hours got a new router from CenturyLink to connect. Finally found your post, the method that worked for me was putting in the Key Phase instead of the pass word.

I tried several fixes and nothing worked until I used the wireless key on the back f my router. Thank you. I rebooted the router, rebooted the Fire, tried the admin password, tried the key, did those steps multiple times, no luck.

Changed my wifi account password, tried that too. Amazon customer service called me and predicted the problem was with my provider not with them — since the Fire connected okay for me at work.

Sounds logical enough. Still stuck, have wasted three hours so far. Maybe will have to fart around with a second comms company now, the CenturyLink helpdesk.

Thanks for the suggestion! Thank you, that worked right away. I put the letters and numbers that are on the bottom of the WiFi box in and it connected. It worked! I turned my FIRE off for a minute, etc. Re-entering the password got it up and running again. Thank you this fixed my problem. Just bought Amazon fire today so frustrated! Will be returning! F THAT! All of a sudden my Kindle Fire no longer allows me to conect to wifi.

I get the following message. Please try again. I am at a new location but I have strong wifi reception on my other devices.

Tried several things still not working. Same thing, happened to me…well kind of.

The Asterisk system is able to make outgoing calls to the same system. But for an incoming call, it wants the other system to be authenticated. I have got all the settings required for no authentication, but still it seems to be not helping. Anyone who would be able to help me with this?

Even after these settings, I get the following message. Thanks for pointing that out. Changed it, does not seem to work though. But it always throws message. Is there something else i am missing? You need both to go forward.

I checked that setting, it is set to Yes only.

It seems the calls were not getting completed because of my extensions having secret. But the logs from the Asterisk were mis-leading, since according to it, the other PBX needed authentication to complete the call. This is mis-leading, and makes us think that CUCM needs authentication to complete the call.
