I'm receiving this message but I can't find the postgresql.conf file:
OperationalError: could not connect to server: Connection refused (0x0000274D/10061)
Is the server running on host "???" and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused (0x0000274D/10061)

On my machine:
C:\Program Files\PostgreSQL\8.4\data\postgresql.conf
postgresql.conf is located in PostgreSQL's data directory. The data directory is configured during the setup and the setting is saved as PGDATA entry in c:\Program Files\PostgreSQL\<version>\pg_env.bat, for example
#ECHO OFF
REM The script sets environment variables helpful for PostgreSQL
#SET PATH="C:\Program Files\PostgreSQL\<version>\bin";%PATH%
#SET PGDATA=D:\PostgreSQL\<version>\data
#SET PGDATABASE=postgres
#SET PGUSER=postgres
#SET PGPORT=5432
#SET PGLOCALEDIR=C:\Program Files\PostgreSQL\<version>\share\locale
Alternatively you can query your database with SHOW config_file; if you are a superuser.
You can find it by following this path
C:\Program Files\PostgreSQL\13\data
On my machine:
C:\Program Files (x86)\OpenERP 6.1-20121026-233219\PostgreSQL\data
you will get postgressql.conf file
C:/programfiles/postgressql/14/data
you will also get the pg_hba to check username password
PGDATA is assumed as ConfigDir under Postgresql, this works under docker and normal installation as well, this is default configuration until not changed explicitly.
on my docker PGDATA is configure as "/var/lib/postgresql/data" hence all configuration can be found under this directory.
#------------------------------------------------------------------------------
# FILE LOCATIONS
#------------------------------------------------------------------------------
# The default values of these variables are driven from the -D command-line
# option or PGDATA environment variable, represented here as ConfigDir.
#data_directory = 'ConfigDir' # use data in another directory
# (change requires restart)
#hba_file = 'ConfigDir/pg_hba.conf' # host-based authentication file
# (change requires restart)
#ident_file = 'ConfigDir/pg_ident.conf' # ident configuration file
# (change requires restart)
# If external_pid_file is not explicitly set, no extra PID file is written.
#external_pid_file = '' # write an extra PID file

I had no issues with accessing my apps running in Ubuntu through WSL from windows until I installed docker and did a reboot.
I checked my hosts configuration file and it looked something like the following:
# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
# Added by Docker Desktop
192.168.1.244 host.docker.internal
192.168.1.244 gateway.docker.internal
# To allow the same kube context to work on the host and the container:
127.0.0.1 kubernetes.docker.internal
# End of section
I commented out the second to last line
# 127.0.0.1 kubernetes.docker.internal
and flushed my dns using
ipconfig /flushdns
but still if I try to access my node app running on port 3001 in wsl my browser gives the "Can't reach this page message"
This isn't an issue with node or my app because I am able to successfully curl my app from the ubuntu terminal
I was able to fix the issue by simply adding the ip address for wsl to my hosts file above the docker declaration:
<ip address of wsl> localhost
I have to run some servers with different names. So I changed the hostname in Windows 10 inside C:\Windows\System32\drivers\etc\hosts. I changed the name from localhost to brandcil.local:
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 brandcil.local
# ::1 brandcil.local
Now when I am running nslookup 127.0.0.1 in powershell terminal, it is showing this:
Server: UnKnown
Address: 192.168.43.1
Name: localhost
Address: 127.0.0.1
I restarted my machine but it does not take effect. How do I change the hostname then?
Changing the hosts file will not change the hostname. It is only used for hostname-IP-resolution. Besides that, each line that begins with # is a comment and not an active configuration. You can rename a computer with the following PowerShell cmdlet:
Rename-Computer -NewName brandcil -Restart
First of all, any line in the hosts file that begins with # is a comment and will be ignored. The file itself tells you this if you read it. Second, the hosts file has nothing to do with your computer's hostname. All you're doing is creating aliases that will only work on the machines you modify the hosts file on. You're not changing the hostname at all. Third, localhost -> 127.0.0.1 is a static mapping no longer controlled by the hosts file so it will always map to 127.0.0.1. Again, the hosts file tells you this if you read it.
To rename your computer go into Settings --> System --> About. There's a "Rename this PC" button.
If you don't want to use that, then I recommend using the Rename-Computer Powershell command.
I would like to change path JVM logs in WebSphere 8.5.5.
Via GUI in: Logging and tracing > NorkomServer > JVM Logs.
There is:
Information required File Name:
${SERVER_LOG_ROOT}/SystemOut.log
I have to change it to: "/opt/logs/SystemOut.log"
Instead use "sed", i must use jython. Any help, please ?
You can run the below wsadmin script (with -lang jython) to update the default file path for SystemOut.log file.
#Update the below Environment variables before running this script
#Enter the nodename below
nodename=''
#Enter the servername below
servername=''
#Set the updated file path below
filename='/opt/logs/SystemOut.log'
#Set the Stream name
#outputStreamRedirect for SystemOut & errorStreamRedirect for SystemError
streamName = 'outputStreamRedirect'
#get the server Id
serverId = AdminConfig.getid('/Cell:/Node:'+nodename+'/Server:'+servername+'')
#get the Stream Id
streamId = AdminConfig.showAttribute(serverId, streamName)
#update the file path
AdminConfig.modify(streamId, [['fileName', filename]])
#Save the changes
AdminConfig.save()
Restart JVM post this change.
Again I need your help.
I'm trying to put my java web site online.
What I use :
MySQL server : command line mysql -V, result : mysql Ver 15.1 Distrib 10.1.23-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2
Cayenne
Debian server
Java (Vaadin)
Packet for query is too large (4739923 > 1048576). You can change this
value on the server by setting the max_allowed_packet' variable.
What I tried :
1. Like the error said, I tried to change the value on the server by doing :
Log on my server
Connect to MySQL with : mysql -u root
Enter : SET GLOBAL max_allowed_packet=1073741824;
then, restart the server with : /etc/init.d/mysql restart
But I still have the error.
2. I took a look to : How to change max_allowed_packet size
But, When I did the nano /etc/mysql/my.cnf, the file looks like (I don't have any [mysql]) :

permitted by applicable law.

Any hint will be very appreciate!
Thanks
EDIT: In /etc/mysql/mariadb.conf.d/50-server.cnf, I changed :
max_allowed_packet = 1073741824
max_connections = 100000
and I added : net_buffer_length = 1048576
For info :
In my workbench, I can see the server variables :
EDIT2 : Now, when I select the variable in command line on the server, I have :
MariaDB [(none)]> SELECT ##global.max_allowed_packet;
+-----------------------------+
| ##global.max_allowed_packet |
+-----------------------------+
| 1073741824 |
+-----------------------------+
1 row in set (0.00 sec)
SOLUTION Because the error was not explicit.
Thanks to com.mysql.jdbc.PacketTooBigException
My cayenne configuration was :
<url value="jdbc:mysql://IPADDRESS:22/DBBASENAME" />
<login userName="ServerUserName" password="ServerPassword" />
But it should be :
<url value="jdbc:mysql://IPADDRESS/DBBASENAME" />
<login userName="MYSQLUserName" password="MYSQLPassword" />
Change it in my.cnf, then restart mysqld.
Better yet, put it in a file under /etc/mysql/mariadb.conf.d/, and specify the section:
[mysqld]
max_allowed_packet = 1073741824
What you did (SET) went away when you restarted. Even so, it only applied to connections that logged in after doing the SET.
I have installed maradns in windows 7 machine, I have configured it, It can able to handle internal requests, But not external ones
marac file
ipv4_bind_addresses = "127.0.0.1"
timestamp_type = 2
random_seed_file = "secret.txt"
csv2 = {}
csv2["myapp.com."] = "db.lan.txt"
upstream_servers = {} # Initialize dictionary variable
upstream_servers["."] = "8.8.8.8, 8.8.4.4"
db.lan.txt
private.% 192.168.1.21 ~
blog.% 192.168.1.16 ~
For external requests, its giving me the below error
C:\Program Files\maradns-2-0-06-win32>askmara.exe Agoogle.com.
# Querying the server with the IP 127.0.0.1
# Remote server said: REFUSED
# NS replies:
# AR replies:
For internal requests, Its working fine as below
C:\Program Files\maradns-2-0-06-win32>askmara.exe Aprivate.myapp.com.
# Querying the server with the IP 127.0.0.1
# Question: Aprivate.myapp.com.
private.myapp.com. +86400 a 192.168.1.21
# NS replies:
#myapp.com. +86400 ns synth-ip-7f000001.myapp.com.
# AR replies:
#synth-ip-7f000001.myapp.com. +86400 a 127.0.0.1
And when i start the server, I am getting a prompt with a warning as well
How to resolve this issue.
i had the same problem.. fixed it by replacing the latest version with the version 1.4..
after that the only i did was run the mkSecretTxt.exe to create the secret.txt file and configured the mararc file like this:
this is my current mararc file:
# Win32-specific MaraRC file; this makes a basic recursive DNS
# server.
hide_disclaimer = "YES"
ipv4_bind_addresses = "127.0.0.1"
recursive_acl = "127.0.0.1/8"
timestamp_type = 2
csv2 = {}
csv2["local.com."] = "db.lan.txt"
# This is insecure until the secret.txt file is edited
random_seed_file = "secret.txt"
upstream_servers = {}
upstream_servers["."] = "208.67.222.222,208.67.220.220"
db.lan.txt
% 192.168.1.33 ~
As you can see i've used the openDNS servers, if your still get the error try them as well.

For anyone following along with this, it seems the current solution as of MaraDNS > 2.0 is to use MaraDNS in conjunction with the included Deadwood recursive server to be able to handle both local and external resolution. I was able to get this working on my Windows 10 machine with the following configs...
Assume that the Windows machine's IP address is 192.168.1.2
In the MaraDNS mararc file:
ipv4_bind_addresses = "127.0.0.1"
timestamp_type = 2
random_seed_file = "secret.txt"
csv2 = {}
csv2["mylocalnet.com."] = "db.lan.txt"
In the db.lan.txt file:
% 192.168.1.XXX ~
And in the Deadwood dwood3rc.txt config file:
upstream_servers = {}
upstream_servers["."]="8.8.8.8, 8.8.4.4"
upstream_servers["mylocalnet.com."]="127.0.0.1"
bind_address="192.168.1.2"
recursive_acl = "127.0.0.1/16, 192.168.1.1/24"
# By default, for security reasons, Deadwood does not allow IPs in the
# 192.168.x.x, 172.[16-31].x.x, 10.x.x.x, 127.x.x.x, 169.254.x.x,
# 224.x.x.x, or 0.0.x.x range. If using Deadwood to resolve names
# on an internal network, uncomment the following line:
filter_rfc1918 = 0
You could potentially set up multiple machines to act as independent servers, but my config above was particular in that in enabled me to run both servers on the same machine. You can see that in the Deadwood config, I'm using Google's DNS servers to handle all upstream requests with the exception of mylocalnet.com. which gets forwarded to localhost and handled by MaraDNS.
From here, you just need to launch both programs and point DNS to 192.168.1.2. Should be good to go!
