To whom it may concern:
I am running CentOS 6.5 on my server.
I keep on receiving the following error when I type in yum update as the root user:
[root#dbtest /]# yum update
Loaded plugins: fastestmirror, security
Setting up Update Process
Loading mirror speeds from cached hostfile
epel/metalink | 14 kB 00:00

http://public-repo-1.hortonworks.com/ambari/centos6/1.x/updates/repodata/repomd.xml: [Errno 14]
PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: Updates-ambari-1.x. Please
verify its path and try again
I am using these two links to assist me:
https://www.webmaster.net/fix-pycurl-error-22-the-requested-url-returned-error-404-not-found/
To the best of my knowledge the reason I think I am getting this error is because there is something wrong with the ambari.repo repository file under the /etc/yum.repos.d directory.
My question is what can I do to fix the ambari.repo file, if anything, and what can I do so that I am able to successfully perform the yum update task without any errors?
This is what is inisde the ambari.repo file. Any help can be greatly appreciated.
One more thing I would like to mention is that I made changes to the CentOS-Base.repo file
That URL is incorrect. A quick search online for ambari repo led me to this page which seems to suggest that the correct path is now http://public-repo-1.hortonworks.com/ambari/centos6/1.x/updates/1.2.3.7/ and that you can get a new repo file from http://public-repo-1.hortonworks.com/ambari/centos6/1.x/updates/1.2.3.7/ambari.repo.

I use WinSCP 5.17 to retrieve files from an FTP, when I retrieve files from the root folder of the FTP all works, but as soon as I try to retrieve the files from the sub-folder it doesn't work.
Here is the instruction I use:
get /Clients/Folder2/Folder3/*.* F:\folder1\folder2\
and this is the error message:
Error listing directory '/Clients/Folder2/Folder3'.
Bad message (badly formatted packet or protocol incompatibility).
Error code: 5
Error message from server: Bad message
Thanks for your help.
Finally I solved the problem, I generated the script from WinSCP GUI and it works.
open ftps://username:password#ftp-adresse.azure.com/ -certificate="ee:5f:af:7c:26:6b:bb:6f:cd:86:6a:2c:03:1e:8f:ab:e7:63:fd:43" -rawsettings FollowDirectorySymlinks=1
cd /Clients/folder2/folder3
lcd "F:\folder1\folder2"
get "*.xlsx"
exit
Im trying to learn Hyperledger Composer but seems to be a relatively new technology, i mean there are few tutorials and few solutions to a lot of questions, tutorial does not mention possible error case when following the commands and which means there are is also no solution for those errors.
I have joined the composer channel in their community chat, looks like its running in Discord or something, and asked the same question without a response, i have a better experience here in SO.
This is the problem: I have deployed my business network, installed it, started it, created my network admin card and imported it, then to test if everything is ok i have to command composer network ping --card NAME-OF-MY-ADMIN-CARD
And this error comes:
juan#JuanDeDios:~/proyectos/inovacion/a3-poliza-microservice$ composer network ping --card admin#a3-policy-microservice
Error: transaction returned with failure: AccessException: Participant 'org.hyperledger.composer.system.NetworkAdmin#admin' does not have 'READ' access to resource 'org.hyperledger.composer.system.Network#a3-policy-microservice#0.0.1'
Command failed
I think that it has to do something with the permission.acl file, and gave permission to everyone to everything so there would not be any restrictions to anyone, and tryied again, but failed.
So i thought i had to uninstall my business network and create it again, i deleted my .bna and my network.card files also so everything would be created again, but the same error result.
My other attempt was to update the business network, but didn't work, the same error happened and I'm sure i didn't miss any step from the tutorial. I do also followed the playground tutorial. What i have not done its to create another app with the Yeoman but i will do if i don't find a solution to this problem which would not require me to create another app.
This were my steps:
1-. Created my app with Yeoman
yo hyperledger-composer:businessnetwork
2-. Selected Apache-2.0 for my license
3-. Created a3-policy-microservice as the name of the business network
4-. Created org.microservice.policy (Yeah i switched names but Im totally aware)
5-. Generated my app with a template selecting the NO option
6-. Created my assets, participants and transactions
7-. Changed my permission rules to mine
8-. I generated the .bna file
composer archive create -t dir -n .
9-. Then installed my bna file
composer network install --card PeerAdmin#hlfv1 --archiveFile a3-policy-microservice#0.0.1.bna
10-. Then started my network and created my networkadmin card
composer network start --networkName a3-policy-network --networkVersion 0.0.1 --networkAdmin admin --networkAdminEnrollSecret adminpw --card PeerAdmin#hlfv1 --file networkadmin.card
11-. Imported my card
composer card import --file networkadmin.card
12-. Tried to ping my network
composer network ping --card admin#a3-poliza-microservice
And the error happens
Later i tried to create everything again shutting down my fabric and started it again and creating the network from the first step.
My other attempt was to change the permissions and upgrade my bna network, but it failed too. Im running out of options
Hope this description its not too long to ignore it. Thanks in advance
thanks for the question!
First possibility is that your network name is a3-policy-network but you're pinging a network called a3-poliza-microservice - once you do get the correct ACLs in place (currently, that's the error you're trying to resolve).
The procedure for upgrade would normally be the procedure below:
After your step 12 (where you can't ping the business network due to restrictive ACL conditions, assuming you are using the right network name) you would have:
Make the changes to to include your System ACLs this time eg.
/**
* Sample access control list.
*/
rule SystemACL {
description: "System ACL to permit all access"
participant: "org.hyperledger.composer.system.Participant"
operation: ALL
resource: "org.hyperledger.composer.system.**"
action: ALLOW
}
rule NetworkAdminUser {
description: "Grant business network administrators full access to user resources"
participant: "org.hyperledger.composer.system.NetworkAdmin"
operation: ALL
resource: "**"
action: ALLOW
}
rule NetworkAdminSystem {
description: "Grant business network administrators full access to system resources"
participant: "org.hyperledger.composer.system.NetworkAdmin"
operation: ALL
resource: "org.hyperledger.composer.system.**"
action: ALLOW
}
Update the "version" field in your existing package.json in your Business Network project directory (ie need to change it next increment - eg. update the version property from 0.0.1 to 0.0.2.)
From the same directory, run the following command:
composer archive create --sourceType dir --sourceName . -a a3-policy-network#0.0.2.bna
Now install the new business network code firstly:
composer network install --card PeerAdmin#hlfv1 --archiveFile a3-policy-network#0.0.2.bna
Then perform the requisite upgrade step (single '-' for short form of the parameter):
composer network upgrade -c PeerAdmin#hlfv1 -n a3-policy-network -V 0.0.2
After a few seconds, ping the network again to see ACL changes are now in effect:
composer network ping -c a3-policy-network
I just downloaded the latest copy of the tar.gz file from the website and the installation instructions indicate the bin/phpstorm.sh needs to be ran, however it is missing.
Please advise.
Try unpacking or downloading the archive again, it's there.

I am trying to set up a BrowserQuest server that runs in openshift
I've been following this readme. Everything seems to go fine, I get to the end and run rhc app show bq and get the following output:

But when I try to access http://bq-plantagenet.rhcloud.com:8080/ in a browser, I get:
The connection has timed out
The server at bq-plantagenet.rhcloud.com is taking too long to respond
My questions are what is going wrong and how can I fix it? Many thanks for your consideration in reading through this and any suggestions you might have for resolving it
You need to access http://bq-plantagenet.rhcloud.com, leave off the port 8080, that is the port you listen on internally. You should also try checking your log files (https://developers.openshift.com/en/managing-log-files.html) to see what errors your application is producing.
I have a Cpanel Server.
It send emails correctly expect from 1 domain which hosted on the server , so when I try to send email from that domain using roundcube or Horde I got the errror
SMTP Error (451): Failed to add recipient "recipient#exmple.com" (Temporary local problem - please try later).
does anyone know why and how to fix this?
I found the porblem:
After reviewing the file /var/log/exim_mainlog using
tail -f /var/log/exim_mainlog
I noticed that the error was:
2013-05-29 20:04:28 SMTP connection from [127.0.0.1]:36797 (TCP/IP connection count = 1)
2013-05-29 20:04:28 lowest numbered MX record points to local host: domain.com (while verifying <user#domain.com> from host localhost.localdomain (domain.com) [127.0.0.1]:36797)
2013-05-29 20:04:28 H=localhost.localdomain (domain.com) [127.0.0.1]:36797 sender verify defer for <user#domain.com>: lowest numbered MX record points to local host
2013-05-29 20:04:28 H=localhost.localdomain (domain.com) [127.0.0.1]:36797 F=<user#domain.com> A=dovecot_login:narena temporarily rejected RCPT <recipient#exmple.com>: Could not complete sender verify
2013-05-29 20:04:28 SMTP connection from localhost.localdomain (domain.com) [127.0.0.1]:36797 closed by QUIT
so the main problem was:
lowest numbered MX record points to local host
after couple of search I found the soluation in http://forums.cpanel.net/f5/lowest-numbered-mx-record-points-local-host-73563.html
which was to:
login to WHM and go to Main >> DNS Functions >> Edit MX Entry for the domain
set MX priority to 0 for the related domain and save.
I had the same problem after running a script to fix directory permissions on a cPanel-powered server (CentOS 6.5). I checked the logfile (tail -f /var/log/exim_mainlog) and found this error:
require_files: error for /home/user_name/etc/domain.com: Permission denied
Just ran the following command and the issue was fixed:
chown -R user_name:mail /home/user_name/etc/
Hope this helps someone.
check the the file /var/log/exim_mainlog to see more information about the error
tail -f /var/log/exim_mainlog
while trying to send email
Check your MX Entry in Cpanel, if the existing domain priority is less than or equals to 0, set it to 1. Mine is fixed. Hope it will help you.
Wow, after about an hour of searching and meddling with different files, I'd caution any novice not to venture out editing anything before you have a backup or image if your server, as you can cause irrevocable damage to your server. So many people talking garbage about what you should do or test without any real solution.
Anyways, here's what worked for me:
Real problem: Exim was updated to latest version which has loads of bugs like this issue.
How I fixed my server:
Authenticate to Linux via SSH and run the command lines through which we download and install the old version of EXIM.
Command Line 1: wget https://ca1.dynanode.net/exim-4.93-3.el7.x86_64.rpm
Command Line 2: rpm -Uvh --oldpackage exim-4.93-3.el7.x86_64.rpm
Command Line 3: systemctl restart exim
Command Line 4: Systemctl restart clamd
Command Line 5: systemctl restart spamassassin
Optional: just type "Reboot" to restart your server
The command lines above does the following:
Downloads the old package (I'm sure you can google other sources with this file)
Install the old package without prompt
Restart the Exim service
Restart the Clamd Service (AV)
Restart the spamassassin service (Spam Filter)
Restart outlook or whatever you use for mail client and send an email. Mine works, hope yours do too.
