Re: [gentoo-user] bind-9.11.1_p3 error with one ipv6 host

[jens w]

the local domain is attached if the host can not be resolved.
sometimes the update with ddnss.de does not work with dualstack,
then there is no  record.

after a correction other dns could give an ip.
the dns my provider does not, which takes somewhat longer 
and was registered as forwarder in my named.conf.

[gentoo-user] bind-9.11.1_p3 error with one ipv6 host

[jens w]

2 times, one error with 1 ddns host, i have 14 ddns hosts.
ping6 martine.ddnss.org give unknown host back.
in named.log I see the hostname with added local domain.
martine.ddnss.org.lxsbbshome.tld.
this happens only at the ipv6/-record, only by this host,
not at the ipv4/A-record.
when I restart named is all ok.
Is that a bind-bug?

I change $HOME in /home/user, but the script not executed.

yes, and the mail-delivery to /home/user/.maildir ist ok, also the
access from roundcube is ok.

real user, real unix useraccount. we will exchange confidential news,
but the user can't use pgp. so he has a local mailaccount, so we change
news via ssl over my mailserver.
when a message arrives for the user, I will send a alert to his
aol-account.

I test the script before, but it works not on nologin-user.

yes and yes.
it works for default user. it does not work for nologin user.
as workaround I forward the mail to a helper-user, and process it there

[gentoo-user] executing a command as a nologin user

[jens w]

.procmailrc
:0 c
* !^X-Loop: n...@example.com
| formail -X "From:" | $HOME/bin/script.sh

procmail.log
procmail: Executing " formail -X "From:" | $HOME/bin/script.sh

for incoming mail, a script is executed. logfile has the same entry as
it is in other users. but the script do nothing.

How executing a command as a nologin user?

[gentoo-user] ipv6 config

[jens w]

on gentoo computer with ipv6 forwarding enabled,
it is assigned by router announcements no ipv6 address.
is a future or a bug?

I register a 6in4 tunnel (Hurricane Electric / www.tunnelbroker.net).
I tried a tunnel to create with ifconfig / HE doc / wiki.gentoo.org /
wiki / IPv6_router_guide. while trying ipv6.google.com ping comes the
message: Destination unreachable: Address unreachable.
I need a hint where I have look for.

bye, jens.
