OpenBSD 5.8 radical CalDAV/CardDAV installation

pkg_add -iv radicale
with auth htpasswd radicale does not start

what is missing?

py-bcrypt has problems with $2b$ hashes :(

forwarding mail with changed sender/from address

Sometimes I want to relay cron mails over an external mail server. In this cases the mail is delivered faster if I set the FROM to the real address that corresponds to the smtp credentials.

all mails to root are forwarded to alex@other-domain.com
But the FROM is changed to alex@strato-mail-account.de

# cat /etc/mail/aliases
...
root: mycron
mycron: "|/usr/bin/mail -s 'Cron <root@example.com>' -r alex@strato-mail-account.de alex@other-domain.com"
...

# newaliases



# cat /etc/mail/smtpd.conf
...
table secrets db:/etc/mail/secrets.db

accept from local for local alias <aliases> deliver to maildir
accept from local for any relay via tls+auth://label@smtp.strato.de auth <secrets>
...

OpenBSD overwrite DHCP values delivered from server

Sometimes the DHCP-Server returns wrong values.
To overwrite the search domain:

# cat /etc/dhclient.conf
...
supersede domain-name "my-new-domain.net"
...

then
# reboot
or
# dhclient  

Now the new value is in the /etc.resolv.conf
