# Development / test scripts
|
||||
|
||||
## `setup_network.sh`
|
||||
|
||||
`setup_network.sh` is used as-is, and as_root :-/
|
||||
This little thing adds some LINUX network namespaces in which you can run mycelium
|
||||
U're a dev so deal with it
|
||||
|
||||
|
||||
## testing mycelium (`bigmush.sh`)
|
||||
This lill skrip will just start $NUMOFNS network namespaces in your LINUX box where you can SUDO (because I __know__ for a fact that you weren't root, of course), start a mycelium daemon in the main namespace and one in each NS.
|
||||
|
||||
### Usage :
|
||||
|
||||
Start with
|
||||
```bash
|
||||
source ./bigmush.sh
|
||||
getmycelium
|
||||
```
|
||||
will get the latest __release__ binary from github
|
||||
|
||||
Then
|
||||
```bash
|
||||
source ./bigmush.sh
|
||||
doit
|
||||
```
|
||||
|
||||
will create and start a 50 node mycelium with one central
|
||||
|
||||
```bash
|
||||
source ./bigmush
|
||||
dropit
|
||||
```
|
||||
will kill with little mercy mycelium daemons and delete the namespaces
|
||||
|
||||
|
||||
```bash
|
||||
source ./bigmush.sh
|
||||
cleanit
|
||||
```
|
||||
will do a `dropit` and clean `*.{bin,out}` files
|
||||
|
||||
```bash
|
||||
showit
|
||||
```
|
||||
|
||||
will send a USR1 signal to all mycelium daemons that will
|
||||
- send routing tables and peers to stdout
|
||||
- where stdout will be captured in `xx.out` for each NS
|
||||
|
||||
### logging
|
||||
every namespace has an `xx.out` file that is stout and stderr
|
||||
the `xx.bin` file is the namespace daemon's privkey.
|
||||
|
||||
### behaviour testing
|
||||
|
||||
1) verify if you can reach all mycelium namespaces
|
||||
2) also when running another machine in your net, verify if it's automatically detected
