ncm-ssh: Invalid configuration file: /dev/stdin

[nowack73]

Running ncm-ssh (version 17.2) on SL7.3 in a non-interactive mode (i.e. started by ncm-cdispd) results in an error:

2017/03/15-13:54:52 -----------------------------------------------------------
2017/03/15-13:54:52 [ERROR] Invalid configuration file: /dev/stdin: Permission denied

2017/03/15-13:54:52 [INFO] configure on component ssh executed, 1 errors, 0 warnings

If I run ncm-ncd --configure ssh interactively in shell, ncm-ssh succeeds:

I believe this is related to which selinux context the component runs in (we also see this error).

[nowack73]

Thanks, for the hint. I set AII_OSINSTALL_SELINUX to 'disabled', but somehow selinux has been installed. With SL6, this was never a problem, but it seems to be a problem with SL7.

[nowack73]

Does this mean that ncm-ssh is not compatible with selinux?

[jrha]

I hope not, I've been looking at this problem today as well (although mostly by trying to ensure selinux is disabled), but we do have use cases that require selinux.

@nowack73 is there a -selinux in the kickstart file? AII_OSINSTALL_SELINUX disabled should not even install selinux (unless something else pulls it in).

[nowack73]

Yes, the kickstart file contains:

selinux --disabled

and

%packages --ignoremissing
-selinux*

But in the ks-post-install phase, some dependencies seem to require selinux-policy and that creates a default /etc/selinux/config with SELINUX=enforcing.
