* #915 Extend GET /repositories with param idJavier Sánchez Parra2022-06-231-2/+5
| | | | | | | | | | | | | | | | | | | | | | Add id parameter to the response. This is useful to identify repositories that have several IPs. Request: GET /repositories { "repositories": [ { "id": 1, "ip": "192.168.56.10", "name": "Repositorio (Default)" } ] } Response: 200 OK Related-to: d5e6dc0 ("#915 Add API GET /repositories")
* #915 Fix missing id on image creationJavier Sánchez Parra2022-06-201-0/+1
| | | | | | | | | | | On image creation, ogServer always sends 0 as image id to clients. When clients sends the response to the "create image" command with new information to update the image's entry in the database, the image id is 0 and ogServer fails to update the image's entry. This patch fixes this, assigning the correct id of the image. Fixes: d2f20d0be0661 ("#942 Create DB image when calling POST /image/create")
* #915 Use the repository id on image listJavier Sánchez Parra2022-06-202-9/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | API "GET /images" shows the repository ID the image belongs to, instead of the IP. This is a preparative commit to the support of repositories with several IPs. Request GET /images Response 200 OK: { "images": [ { "name": "windows10", "datasize": 0, "size": 626088433, "modified": "Fri Jun 10 12:20:32 2022", "permissions": "744", "software_id": 1, "type": 1, "id": 6, "repo_id": 1 } ], "disk": { "total": 52573995008, "free": 38964637696 } }
* #915 Use the repository id on image creationJavier Sánchez Parra2022-06-203-56/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | POST /image/create has two modes, image creation and update. You can find more information about the "creation" mode in commit: d2f20d0be06617f421eecca111449d94672695eb On image creation, use the id to identify repositories instead of the IP. This is a preparative commit to the support of repositories with several IPs. On image update, "repository_id" field is not needed because the image already has the repository assigned. This commit maintains backward compatibility with the Web Console (old web interface), because it only use the "update" mode of /image/create. Request POST /create/image: { "clients": [ "192.168.56.11" ], "disk": "1", "partition": "1", "name": "archlinux", "repository_id": 1, "id": "0", "code": "131", "description": "This is a test", "group_id": 0, "center_id": 1 } Response 200 OK
* #1074 rest: set_mode: add support for different ogserver addressesJavier Sánchez Parra2022-06-012-1/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add foreign key "identornos" from table "entornos" to table "ordenadores". A row in table "entornos" represent a valid ogServer address. Multiple ogServer valid addresses can exist when running several instances or a single ogServer instance is exposed to different networks. Can't delete rows in "entornos" table nor update their id (primary key) if the row has any associated clients ({ON UPDATE/ON DELETE} RESTRICT). Allows assigning different but valid ogServer IPs to clients. Enabling support for multiple instances of ogServer (e.g: load balancing) or exposing a single ogServer instance to different networks (e.g: VLAN). Look up for the valid ogServer IP of a given client when changing a client's mode (og_set_client_mode). Determines valid ogServer IP using a JOIN statement. JOIN entornos USING(identorno) Reuses the fetched ip using a statement variable. @serverip:=entornos.ipserveradm For example, for a two VLAN setup: vlan1 ogserver: 192.168.56.10 vlan2 ogserver: 192.168.57.10 The "entornos" table should look like: identorno ipserveradm ... --------- ----------- ... 1 192.168.56.10 ... 2 192.168.57.10 ... And computers in the "ordenadores" table might look like: idordenador identorno ... ---------- --------- ... 1 1 ... 2 1 ... 3 2 ... 4 2 ... ... ... ... Additionally, splits the SQL query for better readability. Co-authored-by: Jose Guisado <jguisado@soleta.eu>

* #915 Add last_cmd to GET /clients APIJavier Sánchez Parra2022-05-183-2/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "last_cmd" json object contains information of the last command executed by the correspondent client. For now, it only includes "result" string property, which stores "success" if the last command finished correctly or "failure" on the contrary. To populate "result" property, this commit also adds "last_cmd_result" enum attribute to og_client struct. Client response processing fills this attribute according to its success. Clients in WOL_SENT state always have last_cmd->result = "unknown". Request: GET /clients Response: 200 OK { "clients": [ { "addr": "10.141.10.102", "state": "WOL_SENT", "last_cmd": { "result": "unknown" } }, { "addr": "10.141.10.101", "state": "OPG", "speed": 1000, "last_cmd": { "result": "success" } }, { "addr": "10.141.10.100", "state": "OPG", "speed": 1000, "last_cmd": { "result": "failure" } } ] }
* #915 Add support for link speed in the refresh responseJavier Sánchez Parra2022-05-091-0/+6

* #915 Add POST /oglive/set REST requestJavier Sánchez Parra2021-12-171-0/+114
| | | | | | | | | | | | | | | | | | | This patch allows you to update clients' database entry and PXE boot file with the specified ogLive. If you specify either an incorrect or unexisting ogLive, then, clients use the default ogLive image. You can query ogLives installed on the server with ogServer's GET /oglive/list API. If you set the oglive field to "default", then the default ogLive is used. Request: POST /oglive/set { "clients": ["192.168.56.11", "192.168.56.12"], "name": "ogLive-5.4.0-r20200629" } Response: 200 OK
* #1065 split og_status_session_toggleJose M. Guisado2021-12-031-9/+22
| | | | | | | | | | | Handles non usual situations like a client sending more than one event of same type. When toggling, receiving two events of the same type is the same as receiving two different ones (eg. start, then stop).

* #1065 Add support for client eventsJose M. Guisado2021-12-013-1/+78

With this commit, ogServer abstracts both sets and offers them though the API as the set "folder". "grupos" table do not only group rooms, it can group other elements of the database. You can see which kind of elements groups looking at the column "tipo". This commit often refers "rooms group" as group and "computers group" as computers. Request: GET /scopes NO BODY Response 200 OK { "scope": [ { "name": "center1", "type": "center", "id": 1, "scope": [ { "name": "folder1", "type": "folder", "id": 1, "scope": [ { "name": "folder2", "type": "folder", "id": 2, "scope": [] }, { "name": "room1", "type": "room", "id": 2, "scope": [ { "name": "folder3", "type": "folder", "id": 3, "scope": [ { "name": "folder4", "type": "folder", "id": 4, "scope": [] }, { "name": "computer1", "type": "computer", "id": 8, "scope": [], "ip": "192.168.56.12" } ] }, { "name": "computer2", "type": "computer", "id": 7, "scope": [], "ip": "172.18.0.71" } ] } ] }, { "name": "room2", "type": "room", "id": 1, "scope": [] } ] } ] }

* #1065 client: add support for ogclient win stateJose M. Guisado2021-11-173-2/+9
| | | | | | | | | ogClient can be run in windows mode, enabling connection with ogServer when running on a Windows machine. Don't expect the same payload in windows mode as a in live or virtual. Client in windows mode does not send partition setup information, only the status/state. (same case for linux mode)
* #1065 client: add support for ogclient linux stateJose M. Guisado2021-11-173-0/+11
| | | | | | | | | | ogClient can be run in linux mode, intended for exposing some ogServer commands when running in a linux distribution. When connecting with a client in linux mode, do not expect a full partition setup response. Just expect a 'status', and then accept the connection without updating any partition information in the database.
* #1064 revisit error handling from ogClientOpenGnSys Support Team2021-11-122-14/+73
| | | | | | | | | | | | | | | | | | | | 200 => successful command, run next pending command 202 => successful command in progress, do not run next pending command 403 => server sent a malformed HTTP header, should not ever happen, close connection (server is buggy?). 500 => client fails to run command, report error and run next pending command 503 => client is busy, report error and do not run next pending command Anything else, should not ever happen (client is buggy?), close connection with client. On error, when processing response from ogClient, do not close the connection, instead annotate in the database that command was not successful and run next pending command. *Only* if client replies status code 500 set last_cmd to UNSPEC so its state is not BSY as reported by og_client_status function and pending cmds can be sent.
* #1042 incorrect initialization of software profiles arrayOpenGnSys Support Team2021-10-201-2/+3
| | | | | | The position 0 of the software profiles array is not initialized, this triggers a bug randomly on image creation if the position 0 comes zero. Adjust the loop to initialize position 0 accordingly.
* #915 Fix create image payload parsingJose M. Guisado2021-10-192-12/+11
| | | | | | | | | | | | | | | | | Commit 141b0797e17f616d6 introduced command scheduling rest api to ogserver. Part of this changeset included og_json_parse_create_image as a utility funtion to parse the json payload of a "create image" command. og_json_parse_create_image did not include the parsing of optional parameters "description", "center_id" and "group_id". New components like ogCP or ogCLI use these parameters. Fix this by adding a struct og_image member to the struct og_msg_params and assigning it when processing a "create image" command. This could be extended to further payload parsing for image related commands in the future.
* #915 Add POST /image/delete methodJavier Sánchez Parra2021-10-041-0/+90
| | | | | | | | | | Delete operation for images stored in the server. It deletes an image from the database and filesystem, thus images must exists in both places. POST /image/delete { "image": "3" }
* #1061 add timeout to pending scheduled commandsJose M. Guisado2021-09-063-0/+14
| | | | | | | | | | | Pending schedule commands can deny ogLive boot of clients due to filling of pending cmd queue with commands such as "Iniciar Sesión". For example: Using RemotePC to serve clients that do not boot into ogLive will fill up the pending command queue with "Iniciar Sesión". Introduce a safety timeout for pending (scheduled) commands to avoid this situation.
* #1054 Fix og_legacy_partition code buffer sizeJose M. Guisado2021-07-261-1/+2
| | | | | | | | | | | The "code" member of the og_legacy_partition is used to hold the string of the partition type *name* for legacy parameter strings. Example: par=2*cpt=LINUX-SWAP*sfi=LINUX-SWAP*tam=10000000*ope=0 Problem: Buffer size is smaller than possible values for this member. Fix: Increase buffer size up to the max length defined in the DB for the corresponding column.
* #1051 Initialize task_id once in og_cmd_post_schedule_commandJose M. Guisado2021-07-221-7/+7
| | | | | | | | Fixes task_id re-initialization in commit 33d8cecfe. Task id is to be initialized with the "session" value and can be done out of the for loop it was before. Avoiding unnecesary snprintf's with the same value.
* #1052 Populate session column when adding actionsJose M. Guisado2021-07-222-3/+14
| | | | | | | | | | | | | | | | If the scope of a command, procedure or task is related to a group of computers then actions associated with that schedule can share the same session value. og_dbi_add_action was not initializing session value, as it is only used for visualization purposes in the legacy web interface. This patch enables og_dbi_add_action to populate session column by assigning it the id value of the first action related to the scope. Example: Power off command for a room scope of 4 clients will result in 4 actions, a power off for each client. The first action id will determine the session value for the rest.
* #1051 Fix command schedule for several clientsJose M. Guisado2021-07-211-3/+24
| | | | | | | | | | | | | A single command can be schedule for several clients. Commit 141b0797e1 introduces a regression when scheduling a command for several clients, the command only executes successfuly for the first one. Fix it by reintroducing the usage of the 'session' column to group a single command into several actions (one for each client), the web console interface already expects this 'session' column to be set accordingly.

* #915 Filter queued commands by idJavier Sánchez Parra2021-06-161-1/+1
| | | | | | | | | | | | ogServer searches queued commands (formerly actions) in the DB by session. This can lead to problems because session is not an uniquely identifier but an identifier that several commands can share to group them. This commit changes query filter from session to id, ensuring correct results This reverts commit d9b6aadf66655a6713bcacb25d2ea6b01c07e3b5.
* #915 Add POST /procedure/run methodJavier Sánchez Parra2021-06-151-0/+97
| | | | | | | | | | | | | | | | | | | Add ogServer support procedure execution. Now users can send a procedure and a list of clients to ogServer, then ogServer breaks down the procedure into commands (formerly actions) and queues them for each indicated client. TODO: Do not reply 200 OK when the procedure do not exist. Request: POST /procedure/run { "clients": ["192.168.56.11", "192.168.56.12"], "procedure": "33" } Response: 200 OK
* #915 Add procedure/deleteJose M. Guisado2021-06-111-0/+62
| | | | | | | | | | | | Delete operation for procedures stored in the database. POST /procedure/delete { "id": "7" } If no procedure is found returns 200 OK but a syslog call is issued to warn so. Such behavior will likely change in the future.
* #915 Revert filtering actions by id to "sesion" in og_dbi_queue_commandJose M. Guisado2021-06-101-1/+1
| | | | | | | | | | | | | | Commit 141b079 introduced a slight change in how rows from table "acciones" are filtered when queuing a command, from "sesion" column to "idaccion" column. This seemed reasonable, as id column is the one autoincrementing. But remotepc queued commands inserting actions id using a timestamp instead of the action row id. See https://github.com/opengnsys/OpenGnsys/blob/c17ffa5d032a82e8eca61481dd8a8adb8b3fc5b1/admin/WebConsole/rest/remotepc.php#L188 Revert said change as long as remotepc keeps such behavior.
