NFS server/client install fails here...

Installed as

Install follows wiki but nfs4 only and module.

I must be missing something...

[alamahant]

Is

Code: Select all

running?

[CaptainBlood]

@alamahant,
Thks 4 ur support.

To my understanding [nfsv4] has strong implication because CONFIG_RPCSEC_GSS_KRB5 gets forced.

Since I want an off the shelf easy and quick solution for home network, I currently switched to nfsv3.

Code: Select all

emerge -pv net-fs/nfs-utils

Would be nice to get rid of these

Code: Select all

pc.mountd: svc_tli_create: could not open connection for [tp/ud]p6

Could be I later come back to [nfsv4] aiming to figure out how to have it working in a minimalist approach.

Thks 4 ur attention, interest & support

[alamahant]

CONFIG_RPCSEC_GSS_KRB5 gets forced.

I think only if you use sec=krb5(pi) in /etc/exports.
Then you will need also to invoke
rpc.gssd
and
rpc.svcgssd
by adding them in /etc/conf.d/nfs(client).
I am not certain but i think nfs4 uses rpc.idmapd by default.

I have no words ...

[CaptainBlood]

I have no words ...

You have at least FOUR words and A.E.I.O.U. is no more than the ordered list of the FIVE vowels of the alphabet.
It would be much appreciated here if you keep out of the way with what I can't refrain to consider as a trolling like posture since you have no evidences your point is any relevant
to the OP.

Could it have been phrased better by asturm, yes.
Are you a total beginner who does need a complete explenation every time, no.

So please, do not start a heated conversion over something rather silly and please stay on topic. And maybe those config updates could lead to a solution of your journey?

[Hu]

Although there is no specific evidence that the pending updates are relevant, it is standard practice to expect users to address known warnings and errors before trying to debug new problems. OP has shown that there are an unusually large number of pending configuration updates[1] and an erroneous package.env entry.

OP: please get Portage to a state where it is not actively warning about known issues, then try to reproduce your original problem. If you need help resolving these warnings, please ask.

[1]: I think the highest I've ever seen for /etc/portage was less than 10. I've only seen in the many tens when ca-certificates triggers a bulk update in /etc/ssl/certs.

Would be nice to get rid of these

I know it's an old post and maybe you already figured this out by yourself, but I got the same errors because IPv6 was not enabled in the kernel. If you do not want to enable IPv6, you can get rid of the errors by commenting the udp6 and tcp6 lines in /etc/netconfig:

Code: Select all

#udp6       tpi_clts      v     inet6    udp     -       -
#tcp6       tpi_cots_ord  v     inet6    tcp     -       -

Note that if you ever decide to support IPv6, this change may break things and must be undone.
