I have just started playing around with Oracle Weblogic. I am trying to do some scripting using WLST , a commandline tool. I have a test environment set up which has Weblogic 10.3 and Linux 2.6.18 on it. I have managed to log into wlst in the offline/interactive mode.
I now want to connect to the AdminServer in my domain. I am having issues doing so.
Following is the command that I am using:
wls:/offline> connect('username','password','localhost:7002')
Once the command is fired it just shows the cursor blinking and the operation does not timeout.
Using the console I have verified the state of the AdminServer , the user defined in security realm and the listen port of the server.
I am wondering why the above command did not work.
On the other hand I created a test managed server using the administration console and successfully made a connection through wlst using the same command.
Am I missing something ?
Thanks !!
I see two things.
On a default installation, port 7002 is a ssl port. It might not be configured and to use it you should specify the t3s protocol, instead of using default t3.
Also, the server is not listening on localhost. That server has an IP address, and chances are the admin server bound to it. It is not listening to 127.0.0.1.
To tell, issue this command (Linux):
#Linux
netstat -plan | grep 7001.*LISTEN
REM Windows
netstat -a -p tcp -n -o | findstr /R 7001.*LISTENING
You will see something like this (Linux):
tcp 0 0 ::ffff:192.168.1.11:7001 :::* LISTEN 20993/java
You can use the IP address, but might as well use the fully qualified name given by:
nslookup 192.168.1.11
Try again connecting :
connect('username','password','t3://myserver-fqdn.example.com:7001')
Or if SSL is configured, this should work:
connect('username','password','t3s://myserver-fqdn.example.com:7002')
Mohan there could be missing in /etc/hosts file. Please check that other reason could be firewall on the Linux box would making issue.
can you show your connect command for managed server? That may hint us to identify issue.
Did you tried with the 1p addresss as well with t3:// protocol?

I'm newbie to clickhouse, I'm trying to create a clickhouse database on my unbuntu 18.04 remote server, I follow instruction to install click house from DEB package in this link: https://clickhouse.tech/docs/en/getting_started/install/#from-sources
after that when I run command clickhouse-client it shows something like this :
root#busmap-api-test:~# clickhouse-client
ClickHouse client version 20.3.5.21 (official build)
Connecting to localhost:9000 as user default.
Code: 209. DB::NetException: Timeout exceeded while reading from socket (127.0.0.1:9000)
Can someone help me to figure out what is the problem and how I can solve it?
Thanks,
Follow these steps to resolve the issue:
check that clickhouse-server-service started
service clickhouse-server status
check the server logs to find the possible reason
cat /var/log/clickhouse-server/clickhouse-server.err.log
if occured the error 'Address already in use':
{} <Error> Application: Net Exception: Address already in use: [::1]:9000
{} <Error> Application: Net Exception: Address already in use: 127.0.0.1:9000
need to switch CH-server to any other port by editing tcp_port-param in /etc/clickhouse-server/config.xml-file:
..
<tcp_port>9032</tcp_port>
..
restart CH-server service:
service clickhouse-server restart
and connect this way
clickhouse-client --port 9032
I actually had this problem too but I got it working with the default port.
The setting should be this way if you want to connect remotely and be able to use the loopback from localhost.
<listen_host>::1</listen_host>
<listen_host>0.0.0.0</listen_host>
This allows the loopback method to work (i.e clickhouse-client no args) on localhost to connect through the IPV6 route, and the remote connection (i.e clickhouse-client -h <hostname>) through the IPV4 connection.
My original problem was that i only used <listen_host>0.0.0.0</listen_host> in my config which meant theclickhouse-client no args would not work on localhost. And I could not get both to work by adding <listen_host>127.0.0.1</listen_host>
I am trying to run Cassandra (CQL Shell) and I am receiving the following error, I have tried all the google responses to existing questions, nothing has fixed it so far.
Connection error: ('Unable to connect to any servers', {'127.0.0.1': error(10061, "Tried connecting to [('127.0.0.1', 9042)]. Last error: No connection could be made because the target machine actively refused it")})
Before installing Apache Cassandra, JDK must be installed.
Can you make sure the IP address is set correctly on your rpc_address setting in your cassandra.yaml file, on your cassandra server.
Also, you need to make sure port 9042 is open and available for incoming traffic (if your IT department is setting up servers, it is possible this port is blocked, unless otherwise specified...)
Hope it helps.
I also faced the same issue , but may be the below 2 way's can help :
Option 1 :
In my case i haven't started the Cassandra Server and was directly trying to connect to Cassandra.
(a) Firstly start the cassandra server via cmd --> \bin>cassandra.bat -f
and then
(b) Try to connect to it's node --> \bin>cqlsh.bat -u cassandra
Option 2:
Try changing the rpc_address in your cassandra.yaml file to eihter 127.0.0.1 instead of localhost
or to 0.0.0.0 instead of localhost
and then again start the server from new CMD.
I was hoping someone could help.
I am trying to sftp to a remote server that is behind a firewall. I have a proxy setup and can sftp via the unix terminal succesfully. However when using mulesofts SFTP connector I get a timeout. From research it looks like this is because it is run on the JVM.
Mule comes with wrapper.conf to update any jvm settings so I have set the following settings:
wrapper.java.additional.15=-DsocksProxyHost:hostname
wrapper.java.additional.16=-DsocksProxyPort=1080
When I do this the Mule service no longer runs and get the following error:
WrapperManager Error: Unexpected exception opening backend socket: java.net.SocketException: Can't connect to SOCKS proxy:Invalid argument or cannot assign requested address
Hopefully someone can assist.
Thank you.
Perhaps typo in the
-DsocksProxyHost:hostname
Should be = rather than :.
The port is unnecessary, 1080 is the default. Documentation is here, see section 2.4 for SOCKS

Well, after looking for many solutions. I came here now.
I am setting up WHM/cPanel for hosting website. Everything was going smooth but I am stuck on FTP connection (Server sent passive reply with unroutable address. Using server address instead.)
Server Details:
CentOS Linux release 7.2.1511 (Core)
WHM/cPanel Version 11.58.0.13
FTP Server: PureFTPD
Acutal error while connecting
To fix this issue and get FTP working you need to open up more numbered ports so FTP can connect. I assume you are using CSF.
Login to WHM then go to CSF >> Firewall Configuration >>
allow TCP_In 30000:50000 and TCP_Out 30000:50000
Once you made the changes Restart the firewall
Now you need to make changes in FTP config file to use these ports, you will find this file to this location /etc/pure-ftpd.conf
Now you will see a line as follows and you will need to uncomment it
# Port range for passive connections replies. - for firewalling.
PassivePortRange 30000 50000
Restart FTP Service and should work.
Could someone help take a look this weird problem? I'm still not able to connect remotely to my Postgresql.
My Steps:
Download and install the latest Postgresql to my local machine
Setup postgresql
Create a DB
Modify "pg_hba", add row "host all all 0.0.0.0/0 md5"
Modify "postgresql.conf", make sure "listen_addresses = '*'"
Restart postgresql service
Open local PgAdmin, and connect to DB <-- Success!
From Remote desktop, do the same thing as #7 <-- Failed!
Error Message:
"Server doesn't listen"
"Could not connect to server......accepting TCP/IP connections on port 5432?"
I found "TCP 0.0.0.0:5432 Listening" when I type "netstat -a"
I checked firewall, it's not enabled
......
Can someone please help? Does anyone encounter this situation?
P.S, my os is Winserver 2008
Thanks in advance~
If you're connecting to the local machine via RDP then you'll be connecting via localhost and no firewall or LAN/WAN/NAT settings should affect pgadmin.
When you edit the pg_hba and postgresql.conf files Server 2008 doesn't usually let you edit them directly where they are. I usually copy them out edit them and then paste them back in. You'll need to authorise the paste from an Admin account.
I usually have a separate rule in "pg_hba" with "host all all 127.0.0.1/32 md5" for local connections. Also ensure when you restart the service that it is running under the user "postgres" and not as some other user.
