Hello! I have a FreeBSD 9.0 host that is registered in DNS to appear with multiple IP addresses: host some.host.com some.host.com has address a.b.c.x some.host.com has address a.b.d.x some.host.com has address a.b.e.x I built multiple jails to run one service in each following mostly: http://www.freebsd.org/doc/handbook/jails-application.html I am trying to start each of the jails with all network interfaces this machine has configured (with the same IP addressed as interfaces are configured on the host system). For that I have in jail related portion of /etc/rc.conf the following jail_enable="YES" jail_set_hostname_allow="NO" jail_list="http ftp rsync pxe" jail_http_hostname="some.host.com" jail_http_ip="a.b.c.x,a.b.d.x,a.b.e.x" jail_http_rootdir="/jail/http" ... jail_ftp_hostname="some.host.com" jail_ftp_ip="a.b.c.x,a.b.d.x,a.b.e.x" jail_ftp_rootdir="/jail/ftp" ... When I start jails: /etc/rc.d/jail start first in the list jail starts perfectly (and I can verify that service configured to run in it is accessible on all three public IP addresses of the machine), all other jails, however, fail to start with the message some# /etc/rc.d/jail start Configuring jails:. Starting jails: some.host.com some.host.com some.host.com ... cannot start jail "ftp" . If I only leave one IP address in each of the jais, they all start OK. If I configure some jails with different IP (on the same class C network), leaving first jail with multiple IP addresses, e.g.: jail_http_hostname="some.host.com" jail_http_ip="a.b.c.x,a.b.d.x,a.b.e.x" jail_http_rootdir="/jail/http" ... jail_ftp_hostname="some.host.com" jail_ftp_ip="a.b.c.y" jail_ftp_rootdir="/jail/ftp" ... all jails start OK (first with multiple IPs, and other with single different IP). If first (in order of start) jail is with single IP, and next jail is with multiple IPs including the IP of the first one: jail_http_hostname="some.host.com" jail_http_ip="a.b.c.x" jail_http_rootdir="/jail/http" ... jail_ftp_hostname="some.host.com" jail_ftp_ip="a.b.c.x,a.b.d.x,a.b.e.x" jail_ftp_rootdir="/jail/ftp" ... then jail with multiple IPs will not start. I tried to search, but I didn't find anybody mentioning having this problem or having it resolved of just having similar configuration with multiple IPs. Is there something obviously wrong that I'm doing? Is it possible that there is some restriction that will not allow me to have this configuration? Thanks a lot for all your answers!
