- Executed script runs with same privilege as ogClient process.
- Uses subprocess.run instead of subprocess.Popen, it's a bit simpler.
We can't specify executable, though. Shouldn't need so in Linux mode.
- Uses shell=True, keep in mind security considerations listed at:
https://docs.python.org/3/library/subprocess.html#security-considerations
(shlex.quote can be used for unix shells)
Adds a systray icon for linux mode. Uses pystray module. Expects a
favicon.ico stored in the same folder as the main ogclient python
script, but if not found a placeholder image is used.
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",
...
}
ogLive related operations are named inside a 'Linux' folder, also its
python class is named OgLinuxOperations. Rename every 'linux' occurrence
with live to further clarify this folder and operations.
- OgLinuxOperations -> OgLiveOperations
- src/linux/ -> src/live/
Fixes: 1377acee ('Rename 'linux' mode to 'live' mode')
ogClient /setup in linux mode do not support to indicate which table
type the user want to use. It always supposes that the partition table
is MBR/MSDOS.
Add ogClient support to work with GPT tables. Add new field table type
to /setup linux mode that expects a string with "MSDOS" or "GPT".
Example old JSON:
{
"disk": "1",
"cache": "0",
"cache_size": "0",
"partition_setup": [...]
}
Example new JSON:
{
"type": "GPT",
"disk": "1",
"cache": "0",
"cache_size": "0",
"partition_setup": [...]
}
ogClient expect to receive information of 1 disk from the Cloning
Engine's script "getConfiguration". ogAdmClient, the deprecated ogLive
client daemon, supported for several disk.
Add ogClient support for several disk.
Extend ogClient to include more information about the image that has been
created. This patch modifies ogClient to read an info file created by image
creation script, add this info to the JSON response and then remove the file.
Example of new /image/create response:
{
"disk": "1",
"partition": "1",
"code": "131",
"id": "1",
"name": "ubuntu",
"repository": "192.168.56.10",
"software": "Ubuntu 18.04.5 LTS \naccountsservice 0.6.45\n...",
"clonator": "PARTCLONE",
"compressor": "LZOP",
"filesystem": "EXTFS",
"datasize": 2100000
}
New fields are "clonator", "compressor", "filesystem" and "datasize".
When restore image command was sent and the restoration failed, you
could see in WebConsole the image as restored and the command completed,
as it if had not failed. This happened because ogClient did not check
the return code of restoration script.
This commit adds return code check on restore image. So, when return
code is a non-zero value ogClient responses with an error 500. When
ogServer receives this error response, it did not set in the database
the image as restored and command as completed without errors.
Commit 621fb7a7 added class initialization with two parameters. These
two parameters were wrongly initialized, "self." was missing. The call
of these params in other functions of the class was also wrong.
This commit fix the initialization of the parameters of
OgLinuxOperations and fix the calls to these params.
ogClient changed its config file format to json. This patch adapts
ogLinuxOperation to use new config file.

We observed that with the new ogClient the ogLive did not show the
realtime log menu*.
This commit changes the ogClient to launch the browser and show the
realtime log menu when some commands are executed.
* The realtime log menu is a menu that shows current status and info
about the command that the ogLive is executing.
We have observed that the ogLive browser did not show the changes when
an image restoration o script execution was called. The problem was that
the HTML menu was not updated/regenerated in these cases.
This commit adds the call to the HTML regeneration function to image
restore and script execution commands. This way, when the browser is
restarted it loads the updated HTML menu.
We have observed that the browser did not show changes. This happens
because the ogClient opens the browser at the beginning and forget
about it. To show correctly the changes ogClient had to restart the
browser every time the menu html changes.
This commit changes the behaviour to restart the browser when the menu
html has changed.
This patch allows us to execute refresh command using ogClient. This command
gets all the configuration in our machine and send this information to the
server. The format of the message that ogClient will send to the server will be:
{"disk": "1", "partition_setup": [{"partition": "1", "code": "LINUX",
"filesystem": "NTFS", "size": "498688", "format": "0"}, {"partition": "2",
"code": "LINUX", "filesystem": "NTFS", "size": "498688", "format": "0"},
{"partition": "3", "code": "LINUX", "filesystem": "NTFS", "size": "498688",
"format": "0"}]}
This patch allows us to use a new support for creating images using ogClient.
ogClient receives from the server a message which json body must be:
{"disk" : "1", "partition" : "1", "code" : "1", "id" : "1", "name" : "test",
"repository" : "192.168.2.4" }
ogClient returns to the server the software inventory executed before
create the image. The message for the server is:
{ "disk" : "0", "partition" : "1", "software" : "xyz" }
"xyz" will be the output saved during the execution of InventarioSoftware in
a specific path.
This patch adds a new response support. This way allows us to send a new
response message with more information about the partitions already set up.
The format of the response is:
{ "disk" : "1", "cache" : "1", "cache_size" : "0",
"partition_setup": [{"partition": "1", "code": "LINUX", "filesystem": "EMPTY",
"size": "498688", "format": "0"}...]
This patch allows us to send feedback to the server in case of error during
the execution of the command. In case of error, ogClient will send an
"Internal Error" http message.
This patch give us a better support in case of error or success execution.
In error cases, the new behavior is to send an Internal Error http message (500).
Otherwise, the server will receive a message with a json with this format:
{ "hardware" : "xyz" }
"xyz" is the output saved in a specific path during the execution of
InventarioHardware.
During our tests, we found some limitation during the execution of the software
command. We don't manage errors during the execution of this command. Moreover,
the server needs some information in case that everything is OK.
This patch modified the code for controlling the errors during the execution,
returning an "Internal Error" http message (500). Moreover, in case that
everything is OK, ogClient sends a message with this json body:
{ "disk" : "0", "partition" : "1", "software" : "xyz" }
"xyz" will be the output saved during the execution of InventarioSoftware in
a specific path.
This patch allows us to catch an exception when something wrong is happening
executing the init session command. In error cases, ogClient sends an internal
error http message to the server. Otherwise, an OK http message.
Now, all the arguments are received from httpparser. Those arguments convert
the function in long lines of codes. Passing directly the httpparser, all the
function will have less arguments and will be more clear the code.
ogAdmClient has a support to restore image on the machine. This new command
allows the new ogClient to execute the same script to restore the images
on the machine. The json format sent from the server must be:
{ "disk" : "1", "partition" : "1", "name" : "test",\
"repository" : "192.168.56.10", "type" : "UNICAST", "profile": "1", "id": "1"}
ogAdmClient has a support to configure the machines. This new command allows
the new ogClient to execute the same script to configure the machine.
The json format sent from the server must be:
{ "disk" : "1", "cache" : "0", "cache_size" : "70000000",\
"partition_setup": [{"partition": "1", "code": "NTFS", "filesystem": "NTFS",\
"size": "11000000", "format": "0"}]}
ogAdmClient has a support to inventory the hardware in a machine. This new
command allows the new ogClient to execute the same script to inventory the hw.
No arguments needed for executing the command
