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.

On a virtual host server, I have 1 repository that I can no longer checkout from a remote computer. Checkout works fine if I'm checking out on the server itself. All other repositories on the same virtual host server work without a problem, though none of them have as many files as this one.
When I check out on a remote computer, checkout goes a certain number of files, then starts displaying checksum errors, usually between 2 and 6 at a time. If I delete the checked out folder and try again with a new folder, it will stop after about the same number of files, and the collection of files with checksum errors is different from the previous checkout. Checking out on a different remote computer gets the same random results.
First try:

I created a new repository of the same files on the same server. Same problem, except I start getting checksum errors after downloading only about a dozen files instead of a few hundred. The server is on Subversion 1.13.0, Tortoise is 1.13.1.
Any ideas what kind of problem I should be looking for?
My assumption would be that a certain folder has a corrupt checksum (for whatever reason).
Fist of all I'd check integrity of the SVN. Some instyructions can be found here:
https://www.darklaunch.com/fix-svnadmin-checksum-mismatch-while-reading-representation.html
There's quite some people experiencing this issue. The easy work around normally mentioned is to recreate the repo:
Copy the content to a temporary directory
Add the folder as new one to SVN
As the new content will get new checksums, those should be ok for all folders afterwards
If you want to do some direct editing, here's a post that corrected the SVN files successfully (use at own risk, make backups!)
https://maymay.net/blog/2008/06/17/fix-subversion-checksum-mismatch-error-by-editing-svnentries-file/
I once had strange behaviour when content on net packages had been capped as well. That was caused by the MTU (Maximum Transfer Unit). SVN seem to struggle here as well, so adjust the setting in your network infrastructure. Here's a link to a similar issue with SVN involved.
https://serverfault.com/questions/392881/tortoise-svn-repo-browser-checkout-over-vpn
As summary: To isolate the issue I would do the following steps:
A) See if the repo's SVN metadata is cause:
log to server
copy the repo as filesystem (without SVN data)
create a new repo with the files
connect svn client from other host. If all goes well the SVN metadata is corrupt
b) Check if it's host/network specific
Do the same as A but from other host (= create the repo from there)
List item
c) Check if network MTU is ok
do check up to which size packets will be transferred ok (will not go into details as this is very OS/infrastructure related, but you'll find lot's of infos)
note hops/VPNs/multiple routers/IPv4-IPv6 can all play into this
Having written all that: Did you crosscheck behaviour with a second SVN client in the first place? Might be the first thing to do.
I am at my wits end!
I have a minimal install of Ubuntu Server 18.04 and OpenJDK 11 (headless).
Downloaded, to a local folder are the java 9+ binaries for Derby (db-derby-10.15.2.0-bin)
Path and Environment settings are all correct!
When I start the server startNetworkServer -h 0.0.0.0, I get an error when doing a simple connect using the ij command line tool
ij> connect 'jdbc:derby://localhost:1527/dbname;create=true';
ERROR XJ041: DERBY SQL error: ERRORCODE: 40000, SQLSTATE: XJ041, SQLERRMC: Failed to create database 'dbname', see the next exception for details.::SQLSTATE: XBM01::SQLSTATE: XJ001
The derby.log file makes reference to:
java.security.AccessControlException: access denied ("java.lang.RuntimePermission" "getenv.SOURCE_DATE_EPOCH")
Looking further into this error, I learned that I somehow need a security.profile. I found this website that seemed to be the answers to my problems. https://www.javacodegeeks.com/2020/04/apache-derby-database-jvm-security-policy.html
Following these pretty straight-forward instructions, I get:
java.security.AccessControlException: access denied
org.apache.derby.shared.common.security.SystemPermission( "engine", "usederbyinternals" )
For the next person who has this strange problem (it seems to happen with some regularity, here's a simple workaround, copied from this FAQ page at Chalmers Institute of Technology:
Q: When we try to create a database in Derby and the database explorer in NetBeans, we get one or more of the following error(s):
An error occurred while creating the database:
java.sql.NonTransientConnectionException: DERBY SQL error: ERRORCODE:
40000, SQLSTATE: XJ041, SQLERRMC: ...
Caused by: java.security.AccessControlException: access denied
("java.lang.RuntimePermission" "getenv.SOURCE_DATE_EPOCH")
A: This is some kind of missconfiguration in the JVM with a very aggressive security policy that doesn't allow applications to fetch the time on the system (since epoch). The solution is to edit ~/.java.policy or [java.home]/lib/security/java.policy and add the following:
grant {
permission java.lang.RuntimePermission "getenv.SOURCE_DATE_EPOCH", "read";
};
If you are on Windows you can read about where this policy file is supposed to be located here;
https://docs.oracle.com/javase/7/docs/technotes/guides/security/PolicyFiles.html
Apache-Derby is a database management system prepared for a multi-user environment, therefore, when you execute the startNetworkServer -h 0.0.0.0 instruction, you are telling it by default to take certain security into account, and that is why it does not let you do an insecure connection such as ij> connect 'jdbc:derby://172.16.17.31:1527/BBDD_server;create=true';
because you are connecting without specifying username and password, so you should either connect by specifying username + password, or start the server without any security:
startNetworkServer -h 0.0.0.0 -noSecurityManager

I am fairly new to Linux (and brand new to chef) and I have ran into an issue when setting up my chef server. I am trying to create an admin user with the command
sudo chef-server-ctl user-create admin Admin Ladmin admin#example.com
examplepass -f admin.pem
but after I keep getting this error:
ERROR: Connection refused connecting...
ERROR: Connection refused connecting to https://127.0.0.1/users/, retry 5/5
ERROR: Network Error: Connection refused - Connection refused
connecting to https://..., giving up
Check your knife configuration and network settings
I also noticed that when I ran chef-server-ctl I got this output:

I read that this error is due to a prerequisite mistake but I'm uncertain as to what it means or how to fix it. So any input would be greatly appreciated.
Your server does not have a valid FQDN (aka full host name). You'll have to fix this before installing Chef server.
I downloaded the tar.gz file and I'm trying to install Opscenter. I am getting the following error.
ERROR:
Trying to download https://opscenter.datastax.com:443/definitions/5.0.1/version.md5
resulted in following error:
Traceback (most recent call last):

DNSLookupError: DNS lookup failed: address 'opscenter.datastax.com' not found: [Errno -2] Name or service not known.
Do I need to have internet access to install Opscenter?
This error should not prevent OpsCenter from working correctly, you just won’t have update information (for cases when you’re running outdated versions of Cassandra or OpsCenter.)
OpsCenter does not require internet connection.
You should be able to configure OpsCenter to not fetch the updated definition files. Refer to OpsCenter configuration properties and look for the [definitions] auto_update property which you can set to False.
I am trying to downloading some file using this command:
using both SRA toolkit and Aspera Connect
~/source/sratoolkit.2.3.5-2-ubuntu64/bin/prefetch -t ascp -a "~/.aspera/connect/bin/ascp|~/.aspera/connect/etc/asperaweb_id_dsa.openssh" SRR1287825
but It gives me this error
1) Downloading 'SRR1287825'...
Downloading via fasp...
err: process failed while waiting process - ascp failed with 1
fasp download failed
1) failed to download SRR1287825
what is the meaning of error 1 , and what shall I do?
thanks in advance.
I found it the command was not able to solve ~/ I need to put the full path for example /home/user-name/.aspera
