Send a configuration file to FAUCET fails

alshaboti commented 5 years ago

I am using gNMI faucet agent to remotely get and set faucet.yaml file.

gnmi_get works fine, but when I tried to use gnmi_set I get these issues: Note: I am using docker ubuntu:16.04 image.

1- gnmi_set $AUTH -replace=/:$(<faucet.yaml) not working

It results to capture the first line of the faucet.yaml file.

root@8c57dfa15a14:/pegler/etc/faucet# gnmi_set $AUTH -replace=/:$(<faucet.yaml)
== setRequest:
replace: <
path: <
>
val: <
string_val: "acls:"
>
>

2- It works with qutation "$(<faucet.yaml)" but I got a new error "fuser not found"

3- I installed psmisc package for fuser on faucetagent container and now it works (faucet.yaml is replaced and faucet is reloaded), however, it returns an error.

1) README.md issue; fixed in #14 and is now merged 2) Surprising that fuser was missing in 16.04 by default; will add psmisc to deps; fix in #17 3) Can't reproduce yet; @alshaboti could you possibly a) confirm that it happens with the latest FAUCET master b) provide a faucet.yaml that triggers the bug? c) include the output or log file from faucetagent.py?

lantz commented 5 years ago

3) Looks like the same issue as #19 which is technically not a bug but expected behavior with an older version of FAUCET.

Created #20 to add FAUCET version 1.9.3+ version requirement to README.md.

lantz commented 5 years ago

@alshaboti Can you confirm that the same config_files exception occurs with FAUCET version 1.9.3 and FAUCET master?

alshaboti commented 5 years ago

I installed faucet from apt repo as follows.

apt-get install curl gnupg apt-transport-https lsb-release -y \
    && echo "deb https://packagecloud.io/faucetsdn/faucet/$(lsb_release -si
| awk '{print tolower($0)}')/ $(lsb_release -sc) main" | tee
/etc/apt/sources.list.d/faucet.list \
    && curl -L https://packagecloud.io/faucetsdn/faucet/gpgkey | apt-key
add - \
    && apt-get update \
    && apt-get install faucet -y

Yes, you are right, it is because of Facuet version. I installed Faucet using pip3, and it works fine. Faucet version in apt is 1.9.2 and in pip3 is 1.9.4

Thanks

OK, when #20 is merged I will close this.

gizmoguy commented 5 years ago

@alshaboti What distribution and version of linux are you using? I just checked the packaging server and it has debs for faucet 1.9.4.

This command might help you debug:

$ apt-cache policy python3-faucet

alshaboti commented 5 years ago

@gizmoguy I am using ubuntu:16:04, for some reason it was installing 1.9.2. Maybe I forgot to update it. It works fine now. sorry for this part. Thank you.

lantz commented 5 years ago

I think we can declare this as fixed in #20. Thanks everyone.
