I installed 3proxy on freebsd(11.2-RELEASE-p10-HBSD FreeBSD ) which is whith opnsense from ports, but I cannot autoload it after restart
service 3proxy start - works nice
I make /usr/local/etc/rc.d/3proxy
-rwxr-xr-x 1 root wheel 653 Feb 26 20:35 3proxy

But after restart I also see that service is down - how can I do this?
I also thought about crontab and #reboot.
Please help me

I am trying to reset admin user password by using chpasswd.bat as forgot my old password in WSO2 EI 6.5.0 by follows this link
OS: windows 10
prerequisite:
Apache Ant 1.10.7 has been installed in my machine.
environment variable set done.
Since i am using default H2 Database, Copied related H2 JDBC driver into <PRODUCT_HOME>/lib/
goto product path <PRODUCT_HOME>/bin/ and execute below command
chpasswd.bat --db-driver "org.h2.Driver" --db-url "jdbc:h2:./repository/database/WSO2CARBON_DB;DB_CLOSE_ON_EXIT=FALSE;LOCK_TIMEOUT=60000" --db-username "wso2carbon" --db-password "wso2carbon" --username "admin" --new-password "newadmin"
after executing above command getting below log

Error updating credentials for user wso2admin : org.wso2.carbon.user.core.UserStoreException: Error while reading realm configuration from file
C:\Development_Avecto\WSo2EIServers\wso2ei-6.5.0\wso2ei-6.5.0\bin>
some Jar called ant-contrib-1.0b3 placed after getting above error inside apache-ant-1.10.7\lib path
Is there any config i missed? or how to run that chpasswd command in windows 10 to reset password ?
I was able to fix this issue for EI 6.5.0. If you have WSO2 subscription try updating the product. If not follow the instructions below.
Note: I did not have a Windows environment to test hence I fixed this for a Linux environment. You can do a diff between the following file and include the required fixed in the bat file.
Copy the org.wso2.carbon.bootstrap-4.5.3.jar to the ${EI_HOME}/wso2/lib directory. This will get rid of the NoClassDefFoundError issue.
Then update the chpasswd.sh with the following content.

We have recently updated our ruby/elasticbeanstalk platform to AWS Linux 2 / Ruby (Ruby 2.7 running on 64bit Amazon Linux 2/3.2.0)
A part of our Ruby deployment is a delayed_job (daemon gem)
After many attempts to have a bash script from the .platform/hooks/postdeploy/ folder, I have offically declared I am stuck. Here is the error from eb-engine.log:
2020/12/08 04:18:44.162454 [INFO] Running platform hook: .platform/hooks/postdeploy/restart_delayed_job.sh

Here is one of many scripts I have attempted:
#!/bin/bash
#Using similar syntax as the appdeploy pre hooks that is managed by AWS
exec 3>&1 4>&2
trap 'exec 2>&4 1>&3' 0 1 2 3
exec 1>delayed_job_err.out 2>&1

source /tmp/envvars
cd /var/app
cd $EB_APP_CURRENT_DIR
su -s /bin/bash -c "bin/delayed_job restart" $EB_APP_USER```
Here is the delayed_job file:
#!/usr/bin/env ruby
require File.expand_path(File.join(File.dirname(__FILE__), '..', 'config', 'environment'))
require 'delayed/command'
Delayed::Command.new(ARGV).daemonize
As you can see I'm doing my best to load up the env variables. The delayed_job seems to run just fine as root from within the EB Linux 2 host with the env vars loaded.

Any help would be appreciated..
I am also using elasticbeanstalk on Amazon Linux 2
I am using resque which needs a restart postdeploy. Following is my postdeploy hook which restarts resque workers
.platform/hooks/postdeploy/0020_restart_resque_workers.sh
#!/usr/bin/env bash
. /opt/elasticbeanstalk/deployment/env
cd /var/app/current/
su -c "RAILS_ENV=production bundle exec rake resque:restart_workers" webapp ||
echo "resque workers restarted."
true
Notice the environment variable setup. It simply executes /opt/elasticbeanstalk/deployment/env which will give you the environment.
Hope you are able to use above script by simply replcaing command to restart delayed job instead of resque workers.
I am running rsyslog within docker containers to send UDP messages to logstash.
When I log into the docker container, and type:
service rsyslog status
shows:
rsyslogd is not running ... failed!
However, while I am in the container, if I type:
service rsyslog start
It starts up perfectly with no errors and no real sign of why it failed at the start
I CAN NOT FIGURE OUT WHY IT IS FAILING!!!!

We bumped upon the same issue on a Docker 17.03.2-ce image created on CentOS 7.3.1611. The solution is in verifying /etc/rsyslog.conf as per this documentation. Basically, in /etc/rsyslog.conf:
Remove $ModLoad imjournal
Set $OmitLocalLogging to off
Make sure $ModLoad imuxsock is present
Comment out: $IMJournalStateFile imjournal.state
Finally, note that running the rsyslogd or anything else, is the responsibility of the program that is being run inside the container. It is not going to get launched, automatically.
This is my rsyslog.conf in docker container(centos7):
$> cat /etc/rsyslog.conf |grep -vE '^$|^#'
$ModLoad imuxsock # provides support for local system logging (e.g. via logger command)
$WorkDirectory /var/lib/rsyslog
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
$IncludeConfig /etc/rsyslog.d/*.conf
$OmitLocalLogging off
*.info;mail.none;authpriv.none;cron.none /var/log/messages

uucp,news.crit /var/log/spooler

Also i changed /etc/rsyslog.d/listen.conf
#$SystemLogSocketName /run/systemd/journal/syslog
And then
$> rsyslogd -n
Thanks #elinax

Add this line in file entrypoint.sh:

Is this possible to have different versions of Erlang/OTP installed simultaneously on the same platform?
I use Kerl to install Erlang on my machines. Quite easy to use, and allows to have several Erlang systems installed on same machine. You can then easily choose the one you want to use.
It is no only possible, but also very frequent. On my machine I have one version that I installed for development (R13B03) it is the default version when I launch erl.
A second copy of the same version associated with nitrogen. this copy is used when I start my nitrogen website. The version will not change when I will use the R16B.. for development
A partial older version which came with the installation of Wings3D.
Yes, I usually install different versions in my home directory. I build them from source:
./configure --prefix=$HOME/r15b01
make && make install
Then I can choose a version to use with PATH=$HOME/r15b01/bin:$PATH, and compile and run things as usual.
These days I use asdf for this. Install asdf and add the relevant line to your .bashrc, and then run:
asdf plugin add erlang
asdf install erlang 22.3.3
asdf install erlang 23.0.2
Then you can set one of the Erlang versions you just built as the default version:
asdf global erlang 23.0.2
Or you can set it to be used in the current directory and its subdirectories - this will create a .tool-versions file in the current directory:
asdf local erlang 22.3.3
On a Mac, Macport helps switching, even between versions it covers and newer ones.
E.g. with Erlang 17 installed directly from Erlang Solutions, you could switch back to RB1603 (open a new terminal window afterwards):
sudo port activate erlang #R16B03-1_0+hipe+ssl
Switch back to Erlang 17 by _de_activating the Macports install (and open a new terminal window afterwards):
sudo port deactivate erlang #R16B03-1_0+hipe+ssl
List all versions you have installed with:
port installed erlang
Using the Nix package manager there is no need to globally install interpreters (especially because sometimes multiple versions are needed), and nix-shell will open up a sub-shell with the Erlang executable available in the path.
1. Getting only the Erlang (no shell.nix)
For the current version in the active channel:
nix-shell -p erlang
For other versions not in the current channel, a specific channel can be given:
nix-shell -I nixpkgs=channel:nixos-unstable -p erlangR22
Or add path to the Nix expression in your NixOS/nixpkgs clone:
$ nix-shell -I nixpkgs=~/clones/nixpkgs -p erlangR23
2. More elaborate project setup configurations: use a shell.nix file
A complex development environment can be spun up, and calling nix-shell shell.nix will take care of all - even automatically when entering a directory if set up with direnv(archived).

Consider using kerl. It allows you to work with several Erlang installations https://github.com/kerl/kerl
In /etc/thin/ I've got several yml files. When I run service thin stop -C /etc/thin/app.yml thin stops all applications, instead of only the one I specified.
How do I get thin to stop/start only the specified application?
UPDATE: Hmm, in /etc/init.d/thin there's this: $DAEMON restart --all $CONFIG_PATH. That explains a lot. Are there smarter init.d scripts? This is my script:
https://gist.github.com/1003131
See also:
Running Rails apps with thin as a service
you have to edit /etc/init.d/thin adding a new action or modifying the "restart" action.
as you can see, --all $CONFIG_PATH sends the command to all thin instances.
paste the init script somewhere, we can find a decent solution ;)
UPDATE:
try to add the following lines, below this:
restart)
$DAEMON restart --all $CONFIG_PATH
;;
restart-single)
$DAEMON restart -C $2
;;
stop-single)
$DAEMON stop -C $2
;;
I didn't tried it, but it should work well. this is a really simple solution (no error checking), we've added 2 new actions that must be called as:
service thin restart-single /etc/thin/your_app.yml
or
service thin stop-single /etc/thin/your_app.yml
let me know if it works ;)
cheers,
A.
I propose another solution (which i think is more thin-convenient):
set the content of your /etc/init.d/thin file to use my fixes:
#!/bin/sh
### BEGIN INIT INFO
# Provides: thin
# Required-Start: $local_fs $remote_fs
# Required-Stop: $local_fs $remote_fs
# Default-Start: 2 3 4 5
# Default-Stop: S 0 1 6
# Short-Description: thin initscript
# Description: thin
### END INIT INFO
# Original author: Forrest Robertson
# Do NOT "set -e"
DAEMON=/usr/local/bin/thin
SCRIPT_NAME=/etc/init.d/thin
CONFIG_PATH=/etc/thin
# Exit if the package is not installed
[ -x "$DAEMON" ] || exit 0
if [ "X$2" = X ] || [ "X$3" = X ]; then
INSTANCES="--all $CONFIG_PATH"
else
INSTANCES="-C $3"
fi
case "$1" in
start)
$DAEMON start $INSTANCES
;;
stop)
$DAEMON stop $INSTANCES
;;
restart)
$DAEMON restart $INSTANCES
;;
*)
echo "Usage: $SCRIPT_NAME {start|stop|restart} (-C config_file.yml)" >&2
exit 3
;;
esac
:
Use thin restart -C /etc/thin/my_website.yml. It is possible to use such syntax with start, restart and stop commands. Yet, thin restart (or start or stop, of course) would inflict all the instances registered.
This is weird, I added a patch to the script from the gem itself for the init script for the next build to allow a single restart on future installations
restart-file)
$DAEMON restart -C $2
;;
but the gem owner refused the merge and said you can use thin start - C /path/ which is weird, because I've tried it a lot and the script itself says --all and no single config is allowed,
I've also tried doing what he said and obviously it restarted all since the script uses all, can anyone shed more light to this https://github.com/macournoyer/thin/pull/176
