For various reasons, you might not be able to login to the DDP web GUI.
Before starting any troubleshooting, please clear the cache of your web browser, refresh the page and make sure you are using the latest available version of Chrome, Safari, Firefox, Opera or Internet Explorer.
The very first thing that needs to be checked is whether you are able to ping the DDP or not.
It is also recommended to check your client machine network settings in order to make sure they are consistent with the DDP port configuration. If you have any doubt, it is best practice to bypass any switch and directly connect your machine to the DDP first ethernet port which is configured by default as following:
IP address: 172.16.5.4
Submask: 255.255.0.0
MTU: 1500
Flow Control: On
If you can login to the DDP when you are directly connected to the first NIC, the problem is most likely lying on your network/switch configuration.
If you cannot login, remote into the DDP through ssh and restart the web server with the following command:
killall DDPWebServer
After making sure you are using the latest version of your web browser, clearing its cache and refreshing the page, you can move to the next step if you are still not able to log into the DDP web GUI.
It is important to make the difference between three problems:
- When trying to login as an admin to the web GUI and clicking the login button, the password field is cleared and nothing happens.
- After entering your password and clicking the login button, a red message appears saying that the password is wrong.
In the first case, provided that you followed all the previous steps above, this means that the DDP web server does not respond. It can happen when the DDP is (re)booting, when the DDP OS crashed or when it cannot boot properly for another reason. If you are able to ping and ssh the DDP, you can enter the "ps aux" command and see if a process called "webserver" is running. If you can see that process in the list that appears, you can try killing it and it will restart by itself after a few seconds. If you cannot ssh or ping the DDP, please contact us.
In the second case, the red message warning means that the DDP web server is at least active but doesn’t let you in for some reason. Either your admin password is wrong (default password is initial), either the DDP filesystem root is full and some space needs to be released as explained in the root space related topic.
If you believe you are entering a wrong admin password, you can recover it by login to the DDP by ssh and entering the following command:
$ psql -U ddp ddp -c “select m_namest,m_passst from userta”
The command output first lines shoud be similar to the following:
m_namest | m_passst
———-+———-
admin | initial
Next to the the admin username, the password is displayed. You can try to login as an admin once more with that password. In our case, the password is the default one: initial.
If you still get the red error message after this, please contact our team.
