- ## Layout of clientside users private .arctica folder.
- ### Example Folder Tree
- ```

- <A_SSH_SID>.SSH/
- execs.info
- asshm.sock
- opensshm.sock
- fail.log
- drawer/
- <A_CORE_SID>.COR/
- main/
- c2s_<DESC>_<SOCK_FWD_ID>.sock
- s2c_<DESC>_<SOCK_FWD_ID>.sock
- tmp/
- c2s_<SOCK_FWD_ID>.sock
- s2c_<SOCK_FWD_ID>.sock
- teki/
- .tekiable
- c2s_<APPNAME>_<APP_SID>.sock
- s2c_<APPNAME>_<APP_SID>.sock
- ```
- ### Folders Files and Sockets
- #### .arctica/
- *The "home" of all things Arctica*
- I dont think this one warants more explanation.
- #### <A_SSH_SESSION_ID>.SSH/
- *.arctica/<A_SSH_SESSION_ID>.SSH/*
- Individual base folder for an arctica SSH session.
- Created by the respective "Arctica SSH Master" in its initial startup phase.
- #### execs.info
- *.arctica/<A_SSH_SESSION_ID>.SSH/execs.info*
- Plain text file contaning information about various presistent executables
- that pertain to this particular SSH connection.
- First line should be the PID of the parent exec.
- Created by the respective "Arctica SSH Master" in its initial startup phase.
- #### asshm.sock
- *.arctica/<A_SSH_SESSION_ID>.SSH/asshm.sock*
- Control socket for the respective "Arctica SSH Master".
- (Not to be confused with the OpenSSH master socket!)
- Created by the respective "Arctica SSH Master" in its initial startup phase.
- #### opensshm.sock
- *.arctica/<A_SSH_SESSION_ID>.SSH/opensshm.sock*
- Thist is the OpenSSH control socket... created by "ssh"..
- For more info about this socket check out the -S and -M options in the
- openssh ssh man page ("man ssh").
- #### fail.log
- *.arctica/<A_SSH_SESSION_ID>.SSH/fail.log*
- Created by the respective "Arctica SSH Master".
- Should only be created if there is a fatal error that we're unable to report
- through the main arctica errlog/debugging methods.
- [INSERT LINK TO DOCS REGARDING ERROR LOGGING AND DEBUGGING]
- #### drawer/
- *.arctica/<A_SSH_SESSION_ID>.SSH/drawer/*
- A folder where we keep all the sockets (a.k.a. socks) pretaining to respective Arctica Core sessions. Keep in mind that an "Arctica SSH sessions" is not a "Core session".
- The folder shall be created by the respective "Arctica SSH Master" in its initial startup phase.
- [INSERT LINK TO DOCS REGARDING SESSION TYPES]
- #### <A_CORE_SID>.COR/
- *.arctica/<A_SSH_SESSION_ID>.SSH/drawer/<A_CORE_SID>.COR/*
- Future "sepparating" the drawer into folders for each respective "Arctica Core Session".
- Folder is created by the "Core Session Master", which would also clean it up when connection to the respective core session is terminated.
- #### main/
- *.arctica/<A_SSH_SESSION_ID>.SSH/drawer/<A_CORE_SID>.COR/main/*
- This folder should contain somewhat permanent sockets that whould remain in use for the duration of the time we're connected.
- Examples would be sockets for audio or graphics transport.
- Folder is created by the "Core Session Master", which would also clean it up when connection to the respective core session is terminated.
- #### tmp/
- *.arctica/<A_SSH_SESSION_ID>.SSH/drawer/<A_CORE_SID>.COR/tmp/*
- This folder should be used for sittuations where you need a socket forwarded for an individual task. This could for instance be dumping over some raw data in a "scp" fashion. Or just about anything that just needs a socket temporary socket for a very brief moment or individual operation.
- If for instanec you are going to be dumping some data consistently every 5seconds or so. You may want to concider writing up something that you declare as a "main" socket.
- Folder is created by the "Core Session Master", which would also clean it up when connection
