Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind bug

Description
On the remote node, ps command with option --ns does not show the namespace information.

Steps to reproduce the issue:

  1. On the remote node:
    PODMAN_VARLINK_ADDRESS="tcp:127.0.0.1:1234" bin/podman-remote ps --ns

Describe the results you received:

PODMAN_VARLINK_ADDRESS="tcp:127.0.0.1:1234" bin/podman-remote ps --ns                   
ERRO[0000] Could not find flag trace

d93d70b86a2f  rsyslog  13022
512aa9441caa  sadc     13057

Describe the results you expected:
Should have the same result as the podman node does:

[root@localhost ~]# podman ps --ns
CONTAINER ID  NAMES    PID    CGROUPNS    IPC         MNT         NET         PIDNS       USERNS      UTS

Using master I cannot replicate your findings. Here is my example:

Do you suspect the container you created matters?

It's been more than 20 days, I don't have the old created containers now. So I tried it with a new simple container on podman node:

podman run -d busybox sleep 1000

The same result I got on the remote node:

[root@fedora-29 bin]# ./podman-remote ps --ns
CONTAINER ID  NAMES               PID   CGROUPNS  IPC  MNT  NET  PIDNS  USERNS  UTS
a1e86ed01608  focused_mcclintock  6841

But on podman node, it just works fine:

[root@fedora-29-1 ~]# podman ps --ns
CONTAINER ID  NAMES               PID   CGROUPNS    IPC         MNT         NET         PIDNS       USERNS      UTS
a1e86ed01608  focused_mcclintock  6841  4026531835  4026532368  4026532366  4026532294  4026532369  4026531837  4026532367
