Juniper Timeout/Error Connecting #164

Open ben-stratagem opened 3 years ago

ben-stratagem commented 3 years ago

Similar to #162 and #156 - using Hyperglass to query our MX960 for the most part results in a generic error message "Error connecting to $Location: No response."

The ping function works and returns results via Hyperglass but seemingly only for 8.8.8.8 / 8.8.4.4 / 1.1.1.1 (seems to be only short addresses) - any other address or function (traceroute etc) fails with the above error. IPv6 won't return anything. We have dual routing engines and the ping results also include the {master} given on the Junos prompt.

Have tried a slightly older version of Hyperglass but no change. Tried altering the driver to Netmiko and updating the timeout but also no change.

Out of curiosity, if you add structured: false to the device definition, do you have the same issue? I imagine so based no the logs, but just curious.

Also, can you share the logs from changing the driver to Netmiko?

ben-stratagem commented 3 years ago

Hi Matt

The problem does still occur if I updated structured_output to false (structured: false threw an error)

MorningLightMountain713 commented 2 years ago

I came here because of this same error. Testing against a dual RE MX10003. Doesn't work for either Scrapli or Netmiko.

MorningLightMountain713 commented 2 years ago

Figured out my issue here. (some netmiko logging) I was using a read-only user, Juniper read-only by default does not allow ping or traceroute. Have to add them as allow-commands

MorningLightMountain713 commented 2 years ago

This login class works for me, in case anyone else needs it.


    login {
        class lookingglass {
            permissions [ network routing ];
            allow-commands "(set cli .*)|(show route protocol bgp .*)|(ping .*)|(traceroute .*)|(exit)";

Hi @MorningLightMountain713 . What commands are executed under command set "set cli .*"? Thanks so much!

marcelordeo commented 1 year ago

Hello,

I am also having this problem.

I've tried the solution mentioned but it still doesn't do the tracert.

did anyone manage to solve it?

Hello I have a same bug with traceroute on IOS XR

thatmattlove commented 4 months ago

Can anyone re-test this with v2 and update the issue with the results?
