# srl-baseimage
Modified SR Linux container image with some personal enhancements and modifications
* Enable passwordless login for all user accounts by adding a custom global authorized_keys file
* Fix some cosmetic issues with show command output (e.g. column widths)
* Allow 4-byte private ASNs in extended communities, in the range 4<2>00000000..4<2>99999999 (typo in Yang models)
* Install gnmic and pygnmi packages
* Extend CLI with environment variables and dynamic resolution of config references, to enable easy copy&paste of config snippets
# VXLAN traceroute
The code contains a [sample custom tools command](https://github.com/jbemmel/srl-baseimage/blob/main/vxlan_traceroute.py) to invoke standard Linux traceroute with parameters tailored to EVPN VXLAN troubleshooting:
* User selects a VXLAN L2 network-instance (mac-vrf) by name (using auto completion)
* Plugin determines the corresponding VNI and list of VTEP IPs announcing the same VNI
* Plugin invokes 'traceroute' sourced from system0 IP, targeting either all or a single VTEP
# gRPC Network Operations Interface (gNOI)
Some notes and quick start on gNOI:
* [SR Linux documentation for R22.11](https://documentation.nokia.com/srlinux/22-11/SR_Linux_Book_Files/SysMgmt_Guide/gnoi-interface.html)
* Install [gnoic client](https://github.com/karimra/gnoic):
```bash
bash -c "$(curl -sL https://get-gnoic.kmrd.dev)"
```
* Sample command:
```bash
gnoic system time -a clab-spine-leaf-evpn-leaf1 --skip-verify -u admin -p NokiaSrl1!
```
Output:
```
