I am having an error while moving files in Centos, the error is:
rsync: connection unexpectedly closed (643758 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(226) [sender=3.1.2]
It happens to be at the end of the copy process, i saw similar issues online but those issues related with no copying whatsoever, i have 643758 bytes of data moved but cannot finalize it somehow.
Any help will be appreciated.
I'm using Debian and connecting it to Bit vise SSH server, I configured everything is /etc/ssh/sshd_config but when I try to connect using root and its password I get this Error:
The SSH session has terminated with error. Reason: FlowSocketReader: Error receiving bytes. Windows error 10054: An existing connection was forcibly closed by the remote host.
Is there anyway to fix this? I've been searching all night please help
I am trying to transfer a file from Arista switch to an external machine using scp using pyeapi run_command.
Reference:
http://www.nycnetworkers.com/upgrade/copying-from-a-sftp-server/
Code:
import pyeapi
node = pyeayi.connect(transport='https', host='x.x.x.x', username='yyy', password='zzz', enable_pwd='xxx', return_node=True)
node.run_command(['copy flash:/file.log.gz scp://user:password#hostname/location/'], encoding='json')
But it throws the following error,
pyeapi.eapilib.CommandError: Error [1000]: CLI command 2 of 2 'copy flash:/file.log.gz scp:user:password#hostname/location/' failed: could not run command
[Error copying flash:/file.log.gz to scp:user:password#hostname/location/ (Warning: Permanently added 'hostname' (ECDSA) to the list of known hosts.

My existing jenkins master-slave connection got broken . I tried establishing the connection via scp command.
On master:
scp ~/ .ssh/id_rsa.pub jenkins#<my_slave_machine>:/tmp
On slave :
• ssh-keygen –b 2048 –t rsa
• Press enter for " Enter file in which to save the key (/home/jenkins/.ssh/id_rsa) : "
• Press enter for " Enter passphrase (empty for no passphrase):"
• Press enter for " Enter same passphrase again:"
• cd .ssh/
• touch authorized_keys
• chmod 600 authorized_keys
• cat /tmp/id_rsa.pub >> authorized_keys
After trying to connect from UI, getting the below error.

It looks like you're connecting to this server as a user named "dx00926". The simplest explanation for this error is that this "dx00926" user on the remote system doesn't have permission to create files in the directory /home/jenkins, or there's an existing file named "/home/jenkins/slave.jar" there and this user doesn't have permission to overwrite its contents.
Either modify the permission on the /home/jenkins directory to permit dx00926 to create files there, or connect to the remote system with a user that does have permissions to create files there.
Like if you have a username "jenkins" and home dir is "/home/jenkins"
You have to put this home directory in your node configuration, see "Remote root directory: /home/jenkins"
It resolved my issue.. especially for AWS-ec2 and dont set full permission on home directory, it will affect it.
I was having this error. I removed the existing remote.jar in the remote server and try to recreate the agent. It went well now
https://issues.jenkins.io/browse/JENKINS-67258
"Please note, apparently upgrading SSH Build Agents / SSH Slaves Plugin to version 1.32.0 and beyond helps with resolving this problem."
I was having this error, and I tried the above solutions, but the only way I was able to resolve it was by deleting the node, deleting the /opt/jenkins folder, and recreating the folder and the node. After that it worked fine.
sudo chmod -R 777 /home/jenkins
My laptop is running Ubuntu 14.04 LTS. I have a WMD MyCloud that I am doing backups to with an rsync. The rsync calls usually end with an error.
Some things I have observed. The MyCloud machine has a REST API and I see that someone has tried to hack that. As far as I can tell, the attempt did not succeed.
My backup does this from my laptop, to the MyCloud:
/usr/bin/rsync -a -z -v /home/me/ root#192.168.1.82:/shares/me
Usually I get:
rsync: connection unexpectedly closed (93239 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(226) [sender=3.1.0]
and the rsync process is returning 12.
Oddly, if I use a second -v, the process usually succeeds. Why would that be? It is too fast without the second -v?
Something I saw worries me. Again, this is the output on my laptop, running rsync to copy to the MyCloud:
*** stack smashing detected ***: <unknown> terminated
rsync: connection unexpectedly closed (11387 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(226) [sender=3.1.0]
and it returns 12. Ouch!
So, does this mean my laptop is infected with something, presumably Heartbleed or something like it?
On my laptop:
$ rsync -h
rsync version 3.1.0 protocol version 31
...
On the MyCloud:
# rsync -h
rsync version 3.0.9 protocol version 30
...
Am I just screwed? Do I just need to update the stuff on the MyCloud? I have updated by Ubuntu laptop several times. Did that not prevent an infection on this machine?
Open to any suggestions.
