Hello,
Can anyone describe what I doing wrong to get rancid to generate an IOS XR directory listing?
I recently tacacs-enabled an IOS XR router (ASR 9001). I’m using rancid 3.4.1, and tac_plus F4.0.4.14-k6. This is the authorization settings applied:
.
.
.
aaa authorization exec default group TACACS_GROUP local
aaa authorization commands default group TACACS_GROUP
.
.
.
I have this configured in tacacs_plus (among a bunch of other things, but zero deny statements):
.
.
.
service = exec {
# IOS XR and NX-OS both need an exec block, but they need different mutually-exclusive parameters
# task and shell:roles marked as optional to allow them to work together
# IOS XR
# https://community.cisco.com/t5/xr-os-and-platforms/creating-username-passwd-on-ios-xr/m-p/2895304/highlight/true#M7066
# there's also this: https://bst.cloudapps.cisco.com/bugsearch/bug/CSCuj97480
optional task = "#read-only-tg"
# NX-OS
# need it this way to do both N7k and N5k
optional shell:roles="\"network-operator vdc-admin aaa admin\""
}
cmd = dir {
permit .*
}
.
.
.
but I’m getting this result in rancid:
.
.
.

.
.
.
If I check, this is what I see for authorization parameters. Clearly it’s not a tacacs authentication issue on the router, it’s just authorization:
