I have a program on my computer that runs as SYSTEM and it is trying to launch an exe(opc server) on a remote machine x.x.x.x. But I get a DCOM error in my machine's eventviewer.
DCOM got error "2147942405" from the computer x.x.x.x when attempting to activate the server: yyyyy
I followed almost all the suggestions on the internet about opening dcomcnfg and adding users limits.default for launch and activation and Everyone,system,interactive,network from link (ftp://ftp.softing.com/pub/outgoing/opc/DCOM/DCOM-Settings-en.pdf) but nothing works.
Would anybody have nay other ideas on how to make this work.
According to MS Technet:

With my VERY limited understanding of Certificate servers you may have one of the scenarios:
Client PC's are trying to connect to a Certificate server that no longer exists
Client PC's have a certificate that is valid but the Certificate server no longer exists
A Certificate server is broken
Clients do not have the proper authority to request the Certificate
I say this is limited knowledge as I am currently trying to remove AD Certificate services from a Domain Controller and I can see that in the System event log the exact same messages are being logged as I have stopped the Certificate services to asses the impact. If I get further information I will post back.
I'm setting up an Alfresco AWS instance and trying to configure inbound email.
As per the documentation I've configured it, hosted the Alfresco mail server on port 1025, set up an iptable rule to forward port 25 --> 1025, set up an folder in Alfresco with the alias 'dropoff' and added my work email as an allowed user for sending emails. I've also ensured all the ports are open on the EC2 instance
So far so good. If I test everything from my local computer with telnet:
helo mywork.com
mail from:myname#mywork.com
rcpt to:dropoff#alfresco.mywork.com
data
From: adinihan#mywork.com
Subject: test mail from command line
this is test number 1
sent from linux box
.
Then it works. I look in the Alfresco folder and there's the test email document. However, if I use Gmail and sign into myname#mywork.com and send an email through Gmail, then it doesn't work. It sends alright and there's nothing in Alfresco logging, however the document just never appears in the Alfresco folder. The from/to address is the same as the telnet command's one.
Since I can telnet from my local computer to the instance I assume it's not an issue with ports on the EC2 instance. Why would telnet work but sending it via Gmail not?
EDIT: got an email back from Google about an hour after I sent it with the error message TLS Negotiation failed: generic::failed_precondition: starttls error (0): protocol error
EDIT 2: here are my inbound emai settings in the global properties file
# Inbound #
email.inbound.unknownUser=anonymous
email.inbound.enabled=true
email.server.enabled=true
email.server.hideTLS=false
email.server.enableTLS=true
email.server.requireTLS=false
email.server.port=1025
email.server.domain=alfresco.amritmro.com
imap.server.enabled=true
imap.server.port=1143
imap.server.host=0.0.0.0
My play framework web application sends automatically emails to user using Apache commons email library, everything works fine on my machine, but when I deploy it on an Ubuntu server it is unable to send email.
It throws exceptions like org.apache.commons.mail.EmailException: Sending the email to the following server failed : smtp.googlemail.com:465 (I also tried different configuration with smtp.google.mail port 465,25 and 587 with or without ssl and tls)
and connection timed out.
I starting to believe that is a problem of some configuration of my ubuntu server.
Any suggestion?
If i type ufw status command I receive status disabled.
Thanks
I am going to close this question, because I found the solution. Basically my Server provider (Scaleway) has a security configuration where SMTP is blocked. I asked them to unlock It.
Here is the deal.
We have a printer and all our machines have debian in our office. I've configured the printer to send mails to the server (pc00) via its IP (which is static). I created a hubbed_hosts file that tells exim each machine, which IP it has. So my own personal mahcine is ariela#pc01 since I have pc01 and my username is ariela. This should get received in the mbox file. This works in every other machine except mine.
If I print the exim log I get:
ariela#pc01 R=hubbed_hosts T=remote_smtp defer (-44): SMTP error from remote mail server after RCPT TO:<ariela#pc01>: host 192.168.2.101 [192.168.2.101]: 451 Temporary local problem - please try later
It seems as if the problem is in my client machine, howerver I've runned the exim4-config with dpkg-reconfigure for my machine and It is the exact same things as the others that do work. I'm clueless.
Any help would be appreciated.
I've got Jenkins ver 1.524 installed on a Windows 7 box and I'm trying to configure email but the "Test configuration" is reporting errors. Jenkins is running as a service under my own domain account.
My settings are as follows:
SMTP server: smtp.corpdomain.com
Default user email suffix: #corpdomain.com
Not using authentication
Not using SSL
SMTP port: 25
Reply-To Address: tools#corpdomain.com
Charset: UTF-8
When I test the configuration, I usually get the following exception:
javax.mail.MessagingException: Could not connect to SMTP host: smtp.amazon.com, port: 25;
nested exception is:
java.net.ConnectException: Connection timed out: connect
Yet every once in a while I receive the following instead:
com.sun.mail.smtp.SMTPSendFailedException: 553 5.1.8 <nobody#nowhere>... Domain of sender address nobody#nowhere does not exist
;
nested exception is:
com.sun.mail.smtp.SMTPSenderFailedException: 553 5.1.8 <nobody#nowhere>... Domain of sender address nobody#nowhere does not exist
However, I am able to send mail from the command line without errors via both python script and java (using javax.mail) without authentication, and I'm able to telnet to the SMTP server on port 25, so I don't see how it could be a firewall issue.
One other note that may be related: When I try to install a plug-in via the Jenkins web interface, I receive a 403 response for the URL "http://updates.jenkins-ci.org/update-center.json?uctest". However, I'm able to connect to that URL from a browser on the same machine.
Could this be a Tomcat configuration issue? I'm not familiar with Tomcat so I'm not sure where to even start looking. Maybe a Jenkins configuration that I've missed? Any other ideas?
Thanks in advance!
FWIW The nobody#nowhere address is the default address Jenkins comes with for the system admin email address (which is used as the from address when sending emails)
you can change it at
Manage Jenkins > Configure System > Jenkins Location
first, use port 465
second, get your email verified in AWS SES, and change your default sending email from here:
Jenkins -> Configure System -> Jenkins Location -> System Admin e-mail address
Still looks to me like your firewall is blocking Jenkins' service from accessing those ports -
especially as the connection times-out, which is typical for such cases.
Suggest you try to disable the firewall completely and see if there is any change.
Cheers
To check for conectivity problems from Jenkins, I would go to the Script Console at Manage Jenkins -> Script Console, and there, try to connect to the port you want to test (25 in your case), with a Groovy script like:
s = new Socket()
s.setSoTimeout(200)
s.connect(new InetSocketAddress("smtp.corpdomain.com", 25), 200)
s.close()
If you don't receive any kind of IOError, then there is no problem with the conectivity.
Note: I could have used simply new Socket("smtp.corpdomain.com", 25) but it will try forever to connect if the Firewall ignores your attempts.
For the SMTPSendFailedException you eventually receive, as #paul-henry mention:
The nobody#nowhere address is the default address Jenkins comes with for the system admin email address (which is used as the from address when sending emails)
you can change it at
Manage Jenkins > Configure System > Jenkins Location
Resources:
Networking with Groovy
Add a timeout when creating a new Socket
Thanks for submitting an edit. It is only visible to you until it’s been approved by trusted community members
first, use port 465 second, get your email verified in AWS SES, and change your default sending email from here: Jenkins -> Configure System -> Jenkins Location -> System Admin e-mail address
Thanks. It helps me!
My problem was "550-Verification failed for "
