hope everyone will be doing fine.
I am having a problem with sending emails to other domains. I have setup SMTP server on one of the dedicated servers and all the applications on each dedicated server are using this only SMTP. Now emails are not being received on gmail. I have read somewhere that there must be SPF record added to SMTP.
I am just a software engineer and never worked on maintaining the servers or networking, so do not know what to do to add this record.
On many forums, I have read that you must add this using CPanel, I want to know whether can I add this by logging to the dedicated server or I really need CPanel to connect? (Actually I have also forgot the CPanel details, although have requested to hosting provider to retrieve)
Please help me, one might have to give me a detailed info as well as assistance.
Regards
An SPF record must be setup in the DNS zone where the domain is hosted.
Is that on your actual server or are you using external DNS hosting?
In case it's on your own server and you use 'bind', edit the DNS file located at /var/named/domain.com (where domain.com is your actual domain name) and set it up as followed:
domain.com. 14400 IN TXT "v=spf1 a mx ip4:192.168.5.10
~all"
** Comment: 192.168.5.10 is the IP of your mailserver
After this is done, restart the DNS server with /etc/init.d/named restart
To check if your SPF record is setup correctly, check it out via MXTOOLBOX:
http://mxtoolbox.com/spf.aspx
You fill in the domain name there for the domain where the SPF record has just been installed. If it's setup correctly, it will show.
One other small advice I have is to also work with DKIM (especially needed for good delivery to Hotmail).
Yes, If you are using cpanel on your server then you need to enable SPF through cpanel. OR you can use following command to enable SPF for your domain.
/usr/local/cpanel/bin/spf_installer cpusername

I purchased a domain from namecheap, and I'm gonna to use cloudflare to DNS my domain, but it says Error 521.
I created an free instance on Oracle.
Cloudflare suggest me to add their ips to oracle, but I have no idea where to add these ips.
We're from the Solutions Architecture team over at Oracle Cloud Infrastructure and wanted to give you a few pointers to help you out.
What this error indicates, is Cloudflare is having problems accessing your website. Most likely this is because you have not yet configured your website to be accessible from the internet. While we didn't write this, it appears the community has a set of instructions here on how to expose your site to the internet:
https://dev.to/yoursunny/how-to-host-a-website-in-oracle-cloud-free-tier-5hca
Here's another online class for doing the same with wordpress: https://www.udemy.com/course/wordpress-website-built-on-oracle-cloud-always-free-tier/
Once done, you'll want to test your website by IP address in a web browser to make sure you can at least load your web page.
What Cloudflare is suggesting is you should actually only open access to your website from the specific IP addresses of the Cloudflare network. This increases the security of your website by preventing people from bypassing Cloudflare if they know your site's IP address. To do so, instead of adding 0.0.0.0/0 as the allowed CIDR you add an individual entry for each CIDR listed here: https://www.cloudflare.com/ips/
For testing though, just use 0.0.0.0/0 until you have it working. Then you can change it.
Finally, don't forget to check host firewall rules (see iptables --list). Not having a entry for port 80/443 is a common error.
Let us know if it works for you.
I have a similar setup where cloudflare is fronting my app. However, in my case I am just using a public load balancer in OCI. Bought a domainname pointing to the public IP of load balancer. This way first I tested my site without the domain name and just hitting load balancer IP. If that works fine, then in the Cloudflare you just need to proxy the domain to the public IP of LoadBalancer.
I am integrating wirecloud and fiware-idm. Installed both through docker successfully. However, after installing fiware-idm, i am not able to login from admin. username - admin#test.com password - 1234.
Everytime it redirect it to "ip:3000/auth/login". Do I have to make any other configuration in wirecloud or fiware-idm?
Also, even after entering wrong credential, it redirects me to /auth/login and does not display any error message.
My wirecloud, fiware-idm and mysql database are in different containers. Is this can be the issue?
IdM should be deployed on production to be used by WireCloud. That is, you should configure the IDM service using public domains names, using https, and so on... Seems you are creating a local installation, so you should deploy some workarounds. Well, some of those requirements are not enforced by WireCloud, so it should be enough by ensure you use a domain name for accessing the IdM.
You can simulate having the idm server configured using public domains by adding the proper value to /etc/hosts (See this link if you are running windows), the correct value depends on how did you configured the IdM service. So, the idea is to ensure the domain used for accessing the idm resolves to the correct ip address both in the WireCloud container and from your local computer. We can provide you more detailed steps if you provide us more details about how are you launching the different containers.
How to connect MYSQL Database of epizy.com (which is free database provider), to www.mydomain.co.in (which is purchased domain)
Can we connect it!
Have a look what the error is showing here
You need to have hosting first
If your website hosted and working with database on the free host you have mentioned, then you can connect your domain by changing the DNS A records, you will have an IP address which you can browse your website through, copy this IP address and then add it to the domain setting under A/AAAA Records in the DNS manager, after that you may need to wait up to 72 hours to see your website live on the new domain
There are certain free database hosting provider which provides remote access to their database.
Remote access here signifies all the requests made to the database are
originated from their own hosting server (eg, using their hosting
service for php, jsp etc) or any other hosting service provider.
But if remote access is not allowed means all request trying to connect database will be discarded if it's been made from other than their own servers.
So, irrespective of you correct ID and password to the database, you cannot connect to it remotely if blocked by the provider.
000webhost.com, comli.com are such providers for PHP based site
hosting, and, eatj.com is best for testing a Java hosted sites (but
for 11 days trial is only free) all above provider provides free
database hosting.
Turn on error reporting to know exactly what is going wrong.
Or change local host to the websites SQL server
You must have IP for free database provider then you can set this IP as your database HOST.
Also the remote access must be allowed by the server if it is not allowed you can not access your database from different server. Please ask your server support to enable it.
I want to prevent people to access my website outside my home and my father's home. Is it a good idea to check the IP of the connection and to grant the access or is it easily breachable ?
As Jon Egerton already said, your method will work only if IP from your and your father homes are static.
Two other methods for checking allowed connections comes to my mind.
A Login Page requesting for username & password. The example assume you can use php.
Allow only clients with a Certificate installed. The example assume you're using and you can alter configuration of an Apache webserver.
How do I configure SSRS/Windows Server 2003, so that I can setup email delivery via a remote SMTP server that requires username and password.
I can configure SSRS with an SMTP address and other parameters, but nowhere is it possible to configure it with smtp username and password.
I have hunted around, but can only find vague reference to setting up some sort of relay, to cover up the bizarre lack of smtp functionality that SSRS has out of the box.
Any ideas?
Here are the steps to set this up using only Microsoft SSRS/Windows Server 2003 components.
1) Install SMTP server in Add/Remove programs / App Server / IIS
In IIS Manager:
2) add the domain (as a remote type) you will be sending as such as yourwebsite.com
3) Under Default SMTP Virtual Server properties / delivery tab / advaced button, add your remote smtp server in the smart host field.
4) Under Default SMTP Virtual Server properties / delivery tab / Outbound security button, choose Basic Authentication, user name = SMTP user name, password = SMTP password
In the rsreportserver.config file (sql drive:\Program Files\Microsoft SQL Server\MSSQL.3\Reporting Services\ReportServer):
5) Populate <SMTPServer>x.x.x.x</SMTPServer> with the IP of the machine where you just setup the SMTP server.
6) Populate <From>you#yourwebserver.com</From>
7) Change this one to false <SendEmailToUserAlias>False</SendEmailToUserAlias>
8) Lastly, make sure you setup the domain as a permitted host such as this:
<PermittedHosts> <HostName>yourwebsite.com</HostName></PermittedHosts>
As far as why SMTP basic authenication isn't supported directly in SSRS seems to be by design. The best explaination I could find was here on this MSDN forum:
As one poster here mentions, there is a Microsoft Connect ticket open for people who are requesting this functionality.
For sure you have already solved this issue, but let me put here an additional information so others that have this same problem, like me, can solve it by following this how to that Tom Willwerth post.
To solve this issue of SMTP relay just follow the steps above, but be sure to do an additional step, that can be called:
4-a) On Access tab, choose Relay and select "All except the below" on Select which computer may relay through this virtual server:
This will allow all connections to send through this smtp, but be aware that the smtp server will relay anyone who connects to it. If you want to restrict this relay, than you choose "Only the list below" and add the machine you want to relay on.
For more detailed information on this, you can see the source where i found this information on:
http://businessintelligencechronicles.blogspot.com/2010/08/configure-reporting-services-to-use.html
And another thing, the step 8) isn't necessary .
Hope it can be helpful to others and thank you for the information, it helps and now i think one can solve this issue just by following this steps on this link.
Regards
Ps: sorry for the mistakes
This might help you a little: C:\Program Files\Microsoft SQL Server\MSSQL.3\Reporting Services\ReportServer\rsreportserver.config contains all of the configurations settings in the . I don't see exactly what you want so you'll probably have to perform some relay tricks.
