OpenBSD 7.0 stable amf64 My host has two ethernet interfaces, em0 and em1. Note: The host is a VM with two virtual interfaces.
Both interfaces are configured like this for IPv6 in the /etc/hostname.em0 and /etc/hostname.em1 files: inet6 autoconf -temporary -soii They are connected to the same LAN and each produces a unique IPv6 address using the same prefix and an EUI64 interface identifier as expected*. $ ifconfig em0|grep inet6|grep -vE '(fe80:| fd|temporary|deprecated)' inet6 2001:db8::20c:29ff:fd9c:4b7 prefixlen 64 autoconf pltime 1070 vltime 7043 $ ifconfig em1|grep inet6|grep -vE '(fe80:| fd|temporary|deprecated)‘ inet6 2001:db8::20c:29ff:fd9c:4c1 prefixlen 64 autoconf pltime 1032 vltime 7005 DNS records have been set up*: $ dig +short a.example.com aaaa 2001:db8::20c:29ff:fd9c:4b7 $ dig +short b.example.com aaaa 2001:db8::20c:29ff:fd9c:4c1 $ My httpd.conf looks like this*: ipa = "2001:db8::20c:29ff:fd9c:4b7" ipb = "2001:db8::20c:29ff:fd9c:4c1" server "a.example.com" { listen on $ipa port 80 directory index index.html location "/*" { root "/htdocs/a" } } server "b.example.com" { listen on $ipb port 80 directory index index.html location "/*" { root "/htdocs/b" } } /var/www/htdocs/a/index.html and /var/www/htdocs/b/index.html exist and each contains a minimal HTML page. httpd -n sees no problem. rcctl start httpd works fine. However trying to access http://a.example.com or http://[2001:db8::20c:29ff:fd9c:4b7] gets a timeout. Accessing http://b.example.com or http://[2001:db8::20c:29ff:fd9c:4c1] works fine. Trying to find the cause I checked: $ netstat -an|grep LISTEN … tcp6 0 0 2001:db8::.80 *.* LISTEN tcp6 0 0 2001:db8::.80 *.* LISTEN … $ Which seems weird because only the prefix is listed not the complete IPv6 addresses. Am I seeing a bug or is my expectation that both servers (virtual hosts) work wrong? *) Hostnames and IPs anonymized. Thanks! Mike
