I am working on Mac OSX and using bash as my shell. I have been working for the past few hours trying to get the simplest of code to run using Open MPI on multiple computers. After fiddling with configuring Open MPI, I believe I am on the verge of getting the thing to work. However, I have hit a dead end.
The code runs fine without asking other computers over the internet to run it (meaning, I can run it using Open MPI on my own desktop), but when I put in a hostfile and ask a host to run the code I get an error. I think I am connecting to the host fine otherwise, I can ssh to them and do whatever I want, it's just when I run the code.
To produce the following error I run: mpirun -n 4 -hostfile /path/hostfile.txt ./mpi_hello_world. Then it ask for the password on the host I am access, I enter it and then receive the following:
[MyComputer] [[62774,0],0] ORTE_ERROR_LOG: A message is attempting to be sent to

Would anyone be able to give me an idea of what is going wrong here? Thanks for any insight you can offer.

Mautic will not send my queued emails.
I have set up the cron jobs and they are running as expected. The cron job email report for the ":messages:send" cron job that runs every minute is always this...
Processing message queue
Messages sent: 0
Content-type: text/html; charset=UTF-8
I have messages in my queue, which I have sent via the Contacts Tab, by clicking on the contact name (myself) and then clicking on the Send Email button, just to send myself a test email.
In my configuration email settings I am using PHP Mail.
If I have the mail set to 'Send Immediately' it works fine. I get my test email instantly. But if I have it set to queue the message goes into my spool/default folder but when the cron job triggers it is not sent.
Things I have tried so far....
I deleted the cache folder contents
I checked to see if I have two versions of this file: SendChannelBroadcastCommand.php - I don't, I just have this file once, in the ChannelBundle/Command folder. It is not also in the CoreBundle/Command folder (as suggested by a similar post)
I deleted all of the queued messages in the spool/default folder, then sent some more... which are now sitting in the folder just like before.
Things that might be a factor?
The permissions for the file SendChannelBroadcastCommand.php is set to 644. I don't know if this is correct but assume it is.
When I open the SendChannelBroadcastCommand.php file in dreamweaver, it flags it with lots of syntax errors. I don't really know enough about code to determine if these are genuine errors or if Dreamwaever is just being a little too sensitive. I also don't know if this file in included inside another one that'd make those errors disappear if Dreamweaver could see the complete end result, but I thought it was worth a mention.
Things that I'm sure are not a problem
I'm certain that the cron job is set up correctly. It is running. And I receive the email reports (although I've turned those back off now as I don't want a report every minute)
I've seen this problem mentioned a few times on other forums but none of the solutions are working for me.
My Mautic installation is 2.14.0
My PHP is 7.0.31
Installation was via Softaculous on cPanel on a dedicated server hosted with Namecheap
Thank you in advance for any suggestions that I can try to fix this issue.
Steve.
Oh, in case you're wondering... I am using PHP Mail as Mautic would not connect to Amazon SES. For that I get the following error (which my hosting company was unable to help me fix, so I'm trying PHP mail)
Connection could not be established with host email-smtp.us-east-1.amazonaws.com [Connection refused #111] Log data: ++ Starting Mautic\EmailBundle\Swiftmailer\Transport\AmazonTransport !! Connection could not be established with host email-smtp.us-east-1.amazonaws.com [Connection refused #111] (code: 0)
++ Starting Mautic\EmailBundle\Swiftmailer\Transport\AmazonTransport !! Connection could not be established with host email-smtp.us-east-1.amazonaws.com [Connection refused #111] (code: 0)
Regarding your Amazon SES Connection refused #111] (code: 0) error, it is hard-coded in mautic to use port 2587 to connect to amazon ses, regardless of what port you put in the smtp port number. This is in Mautic 2.13.1 version. Make sure TCP 2587 in/out is open on your webserver firewall. This change solved that error message for me. Have not expierenced a queue error, sorry can't comment on that.
If your queue setup is perfect then there is one more thing is there to setup in cron level.
That is php /path/to/mautic/bin/console mautic:emails:send
This command is used to process queued emails for Mautic
Check this for more info https://docs.mautic.org/en/setup/cron-jobs
Due to this only the emails are not processing, if your queue setup is good.
Just add the command and try again, it will work.
I've got a function that I'm trying to run on my puppetmaster on each client run. It runs just fine on the puppetmaster itself, but it causes the agent runs to fail on the nodes because of the following error:
Error: Could not retrieve catalog from remote server: Error 400 on SERVER: uninitialized constant Puppet::Parser::Functions::<my_module>
I'm not really sure why. I enabled debug logging on the master via config.ru, but I see the same error in the logs with no more useful messages.
What other steps can I take to debug this?
Update:
Adding some extra details.
Puppet Community, with Foreman connected Puppetmaster running on Apache2 with Passenger / Rack
Both client and master are running Puppet 3.7.5
Both client and master are Ubuntu 14.04
Both client and master are using Ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]
Pluginsync is enabled
The custom function works fine on the puppetmaster when run run as part of the puppetmaster's manifest (it's a client of itself) or using puppet apply directly on the server.
The function is present on the clients, and when I update for debugging purposes I do see the file appear on the client side.
I cannot paste the function here unfortunately because it is proprietary code. It does rely on the aws-sdk, but I have verified that that ruby gem is present on both the client and the master side, with the same version in both places. I've even tried surrounding the entire function with:
begin
rescue LoadError
end
and have the same result.
This is embarrassingly stupid, but it turns out I had somehow never noticed that I hadn't actually included this line in my function:
require 'aws-sdk'
And so the error I was receiving:
uninitialized constant Puppet::Parser::Functions::Aws
Was actually referring to the AWS SDK being missing, and not a problem with the puppet module itself (which was also confusingly named aws), which is how I was interpreting it. Basically, I banged my head against the wall for several days over a painfully silly mistake. Apologies to all who tried to help me :)
I am scraping a site for data every 50-90 seconds randomly using a C# console application running on .net 4.5. There are couple of values I am posting to the site and based off the returned value I kick off some other process. The problem is after say about a thousand hits or so I get what looks like a DNS error. I am trying to sort out what the source of the problem is first, before trying to fix it. Here below are some of the errors I see in my logs:
The remote name could not be resolved
Unable to connect to the remote server
Unexpected character encountered while parsing value <. Path '',
line 0, position 0.
Unable to read data from the transport connection An existing
connection was forcibly closed by the remote host.
Unable to read data from the transport connection An established
connection was aborted by the software in your host machine.
About 60% of the time I have got the first error. The remaining 40% is divided between the rest of the errors listed above.Are these issues caused by the website I am scraping or by the DNS servers on my end or something else? For all practical purposes the website I am scraping is ok with it as long as I keep the interval between automated hits above 45 seconds which I am doing. The data I am downloading is on an average about 30KB per hit. Please help me understand what could be going wrong and what things I could try to fix this.
I'd say you're running against an automated system designed to protect the site against a DDoS attack http://en.wikipedia.org/wiki/Denial-of-service_attack.
It's seeing that your same IP address is hitting it repeatedly in a short space of time and is simply blocking your resolution of the eventual server.
I was using ftp and successfully connecting to the host.
Then I do
mget test.tar.gz
Even though it successfully test.tar.gz, I have to check the size of the file manually with ls -l command in the other terminal. Is there any way that mget or some other command will indicate to me that the transfer of the file is complete.
It depends a bit on the implementation of the FTP server, but in most cases you should receive something like
250 transfer complete.
250 basically is the return code for Requested file action okay, completed. while the text messages differ sometimes between servers.
In order to make sure you see all the return codes, run your ftp with -v, which enables verbose mode. This forces ftp (and many other linux ftp clients I know of) to show all responses from the remote server, as well as report on data transfer statistics.
A list of most server return codes can be found here.
I am working with wpa_supplicant-0.7.3 .
Some time password entry by a user is wrong and it cause connection error.
I want to know , how to obtain the cause of connection error of wpa_supplicant in normal mode with status or event notice?
The wpa_supplicant logs would indicate a reason code for failure. Look at the wpa_supplicant header file to find the reason corresponding to the code (src/common/defs.h)
