Hi folks,
problem using opensmtpd 6.0.3 on Debian: I have set
xname=mailhost.example.com
:
limit mta inet4
listen on lo tls pki $xname
listen on eth0 tls pki $xname
listen on eth1 tls pki $xname
:
in smtpd.conf, but apparently this "limit" line ignored. At boot
time it tries to bind to a link-local IPv6 address. And this fails,
as strace shows:
:
695 setsockopt(11, SOL_SOCKET, SO_REUSEADDR, [1], 4 <unfinished ...>
695 <... setsockopt resumed> ) = 0
695 bind(11, {sa_family=AF_INET, sin_port=htons(25),
sin_addr=inet_addr("10.0.0.2")}, 16 <unfinished ...>
695 <... bind resumed> ) = 0
695 socket(PF_INET6, SOCK_STREAM, IPPROTO_IP <unfinished ...>
695 <... socket resumed> ) = 12
695 setsockopt(12, SOL_SOCKET, SO_REUSEADDR, [1], 4 <unfinished ...>
695 <... setsockopt resumed> ) = 0
695 setsockopt(12, SOL_IPV6, IPV6_V6ONLY, [1], 4 <unfinished ...>
695 <... setsockopt resumed> ) = 0
695 bind(12, {sa_family=AF_INET6, sin6_port=htons(25), inet_pton(AF_INET6,
"fe80::216:3aff:feca:38bb", &sin6_addr), sin6_flowinfo=0,
sin6_scope_id=if_nametoindex("eth0")}, 28 <unfinished ...>
695 <... bind resumed> ) = -1 EADDRNOTAVAIL (Cannot assign
requested address)
695 write(2, "pony express: smtpd: bind: Canno"..., 59 <unfinished ...>
695 <... write resumed> ) = 59
695 exit_group(1) = ?
695 +++ exited with 1 +++
"ip address show" (run immediately before smtpd) shows, that
the link-local address is still "tentative":
:
194: eth0@if195: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state
UP group default qlen 1000
link/ether 00:16:3a:ca:38:bb brd ff:ff:ff:ff:ff:ff
inet 10.0.0.2/24 brd 10.0.0.255 scope global eth0
valid_lft forever preferred_lft forever
inet6 fe80::216:3aff:feca:38bb/64 scope link tentative
valid_lft forever preferred_lft forever
:
If I try to run smtpd later, then it works.
Every helpful comment is highly appreciated.
