* #1065 Fix windows not reattempting refused connectionsJose M. Guisado2021-11-231-1/+5
| | | | | | | | | Windows does not report a refused connection the same way as Linux. Unsuccesful connect socket will be kept in the exceptfds, and won't be in the readable nor writable fds. The socket in this state will have SO_ERROR set to ECONNREFUSED. On the other hand, Linux does not use exceptfds for such case.
* #1065 revisit config_path initializationJose M. Guisado2021-11-181-1/+4
| | | | | | | If current platform is Linux (either live, virtual or linux) expect /opt/opengnsys/ogclient/cfg/ to contain ogclient.json. If current platform is not Linux then we fallback to current directory.
* #1065 Add windows modeJose M. Guisado2021-11-181-1/+1
| | | | | | | | | | | | Add agent mode for windows platform. Subprocess module for shell/run is cross-platform an no change was needed. The subprocess will run with the same privilege as its parent, ogclient. TODO: Provide a windows installer. As of now, an administrator needs to install python and required libraries for this mode to be usable.
* #1065 src: add linux modeJose M. Guisado2021-11-151-1/+1
| | | | | | | | | | | | | | | | | | | | | ogClient can run in "linux" mode. In addition to live or virtual. Serves as a substitute to the legacy ogagent, which has not received any updates since 2020/07/23. Linux mode initially supports remote reboot and poweroff. Requires updated ogServer with the Linux ogclient state. ogClient can be set up to run in linux mode by specifying it in ogclient.json: { "opengnsys": { "ip": "192.168.56.10", "port": 8889, "log": "DEBUG", "mode": "linux", ... }
* #1056 stop thread if connection with server is lostOpenGnSys Support Team2021-11-111-0/+1
| | | | | | | | | | | | | | | | Abort command if the connection with the server is lost. Otherwise, a race condition that leaves ogServer and ogClient out-of-sync might occur: 1. ogClient is busy running a command (on the worker thread), for example, image/restore. 2. ogServer is stopped OR ogClient loses connection with ogServer (due to transient network problem). 3. ogClient reconnects and ogServer sends a refresh command. 4. ogClient worker thread finishes and it sends a reply to image/restore. 5. ogServer gets confused because it expects a reply to the refresh command, not the old image/restore.
* #1056 stop request processing on connection closureOpenGnSys Support Team2021-07-151-1/+1
| | | | | | If server closes the connection, close the socket, reconnect and stop processing. self.connect() already cleans up the internal state, including the socket state.
* #1056 add cleanup method and use itOpenGnSys Support Team2021-07-151-10/+8
| | | | add method to clean up interval socket state and use it
* #1000 Fix HTTP request header length parsingJavier Sánchez Parra2021-07-131-3/+4
| | | | | | | | | | | | | | | | | | | OgClient miscalculates the body size of the request. ogServer delimits HTTP headers with "\r\n\r\n" to comply with RFC 2616. But ogClient searches for the first "\r\n" delimiter, hence, ogClient stops at the first HTTP header field instead of at the end of the header. Hence, it incorrectly assumes the body starts after the first "\r\n". This commit updates ogClient to search for the "\r\n\r\n" delimiter. Example: POST /shell/run HTTP/1.1\r\n <-- ogClient considers body starts here (WRONG!) Content-Length: 952\r\n Content-Type: application/json\r\n \r\n <-- Here is where the body starts {"json-body":...}
* ogClient is AGPLv3+OpenGnSys Support Team2021-05-141-3/+3
| | | | Update license header in files.
* #980 Broken TCP connection times out after 120 seconds through keepaliveOpenGnSys Support Team2021-04-231-0/+5
| | | | | Enable TCP keepalive to detect if the ogServer is gone (hard reset). If no reply after 120 seconds, then release the connection to the server.
* #1000 Fix ogClient HTTP length handlingJavier Sánchez Parra2020-08-251-4/+9
| | | | | | | | | | | | | | | | | | | | Irina reports that "Partition assistant"/"Asistente de particionado" is not working. This is happening because ogClient is not reading the full data ogServer sends when the entire HTTP PDU is larger than 1024. However, ogClient should read the whole message, reading until read data length is greater or equal to "Content-Length" header value. ogClient fails to obtain "Content-Length" value because is looking for "content-length", be aware of the case sensitivity. It also needs to take into account the header length because read data length also includes headers. This patch updates ogClient to: 1) look for "Content-Length instead of "content-length". 2) compare read date length with content length plus headers length.
* #999 Fix ogClient session commandJavier Sánchez Parra2020-08-211-0/+1
| | | | | | | | | Disconnect gracefully from ogServer after booting OS, the script to start the OS calls kexec, so everything is gone after it. For Windows, this results in a reboot. This commit also improves the disconnect function to make sure the disconnection is synchronous.
* Rename 'linux' mode to 'live' modeRoberto Hueso Gómez2020-06-051-1/+1
| | | | 'linux' represents ogLive mode that is the reason for the rename.
* Delete ogConfig.pyRoberto Hueso Gómez2020-06-051-0/+2
| | | | | This file is only used for its OG_PATH variable, this variable is now in ogClient.

* Add session command to init the opengnsys sessionAlvaro Neira Ayuso2020-01-191-1/+1
| | | | | | | | ogAdmClient has a support for initializing the session in the machine. This new command allows the new ogClient to execute the same script to init the session. The arguments will be received from the server as a json message. Format: { "disk" : "0", "partition" : "1"}
* Add shell run and output commandsAlvaro Neira Ayuso2020-01-191-2/+2
| | | | | | | | Opengnsys needs a support to execute commands on the machine. This patch adds the support for executing two new commands "shell/run" and "shell/output". The first one, give us the support for executing a command in the machine and keep save in a queue the output. The second one, give us the support for sending the output from the command executed.
* Merge ogRest and ogProcess to have only one classAlvaro Neira Ayuso2020-01-191-3/+3

* Include disconnect and send function on client sideAlvaro Neira Ayuso2020-01-191-2/+9
| | | | | | | | | To disconnect the socket or send a message we use in different parts of the code the attribute socket which is declared inside of the client. This way will create us important problem in the future if we want to change the behavior in our client sockets. This patch adds two new methods inside the client and we can use them in other classes giving us the easy way to send messages and disconnect the client.
* Add ogRest class to generate API Rest ResponsesAlvaro Neira Ayuso2020-01-191-4/+5
| | | | | This class now, allow us to generate API Rest responses. In the future, the idea is to complete this class with get and post messages if it's needed.
* Port program to Python 3Alvaro Neira Ayuso2020-01-191-15/+17
| | | | | Python 2.7 will be deprecated in January of 2020. So, we need to have the program with a supported api.
* Remove unneeded logsAlvaro Neira Ayuso2020-01-191-3/+0

* Send bad request when the APIRest operation is not supportedAlvaro Neira Ayuso2020-01-191-3/+4
| | | | | | | | | | | | | | Our program sends always the HTTP message: HTTP/1.0 200 OK but if the operation sent is not supported, we are sending the same correct message. This patch add the support to check if the message is supported. If the message is not supported, we are going to send: HTTP/1.0 400 Bad request\r\n\r\n Otherwise, in operations supported: HTTP/1.0 200 OK
* Execute socket loop on run socket functionAlvaro Neira Ayuso2020-01-191-0/+20
| | | | Ported code from main function to a client function for clearing the main loop.
* Add ogProcess and ogOperation for linuxAlvaro Neira Ayuso2020-01-191-0/+5
| | | | | Thoses new classes allows us to process and execute commands from server side sent using HTTP format.
* Add HTTP parser supportAlvaro Neira Ayuso2020-01-191-11/+4
| | | | | | The new OpenGnsys support to communicate server and client side will be HTTP. This new class allows us the support for parsing all the message received from the server in HTTP format.
* Modify Client state to use enumAlvaro Neira Ayuso2020-01-191-6/+8
| | | | | | | | | During our connections, we are using states to control the Client Socket. We defined using global variables. In case that we modify this global variable, we need to change it in serveral parts of the code. Using enums and declaring a new class, we can redefine the values or create new states without changing the same code in differents python files.
* Create new ogClientAlvaro Neira Ayuso2020-01-191-0/+95
This commit init the new ogClient. The new ogClient has support for configuring and for connecting with the ogAdminServer.
