Unable to connect #49

Closed loibi closed 5 years ago

loibi commented 5 years ago

Got some weird Issues with Connection.

Can connect to the switch. But when I want to connect again with the same Creds after some Minutes it just says "Unable to connect" After w8ing for 1 Day it works again for some time Any Ideas?

Hi,

What release do you are using ? 

Get-Module PowerArubaSW

What the switch and firmware ?

There is a "REST Timeout" (300 secs by default if remember), and it is may this problem (but you have a warning on this case...)

You can get this REST Timeout 

Get-ArubaSWRestSessionTimeout

and configure

Set-ArubaSWRestSessionTimeout -timeout 7200

Hi 0.5 Firmware 16.07 have the default Timeout to 300 Secs

Strange thing - in Switch logs I get "no free REST Sessions available"

Only getting the error when trying to run it from our Monitoring Tool in Background - not in interactive Windows Session. Also need to be logged out from Web Interface to get it working

Hi,

Ok ! it is because you don't disconnect your session and it is limited to 5 sessions Add 

Disconnect-ArubaSW (-noconfirm)

at the end of your script

or look to reuse the same session (look $DefaultArubaSWConnection global variable)

Hi. Tried that already, but still got same behaviour. Looks like some session Problems?

I try and get the same issue when launch more of 5 sessions... but if i use Disconnect-ArubaSW it is working for me (with 16.06 firmware)

Do you are sure don't have forget to disconnect on your code ?

loibi commented 5 years ago

Tried – still getting the same ☹

Using the Script from interactive Windows RDP Session -> OK Using it on the same Server via the Monitoring Software -> Unable to Login and no rest Sessions in Events

Dont understand why

I think I found something.

When it does not work: Getting 2 Event entries with xx logged in from REST on the switch. But Output from the Script is: VERBOSE: POST http://switch/rest/v4/login-sessions with -1-byte payload VERBOSE: received -1-byte response of content type application/json Unable to connect

So Login ist ok but then something happens and whole script breaks?

When this happens 3 Times then I am above the 5 Sessions because script does not come to the disconnect at the end

No, there is no 2 connect

there is some other query (get) but can be disable with -noverbose

With next version (0.6), there is a enhance to be more fast (via Disable HTTP KeepAlive...)

alagoutte commented 5 years ago

Can you send me a email (my email is available on the top of ps1 file like https://github.com/PowerAruba/PowerArubaSW/blob/master/PowerArubaSW/Public/Connection.ps1 )

alagoutte commented 5 years ago

Patch for add -usebasicparsing and enhance info when fail to connect are merged and it will be available on 0.6
