I have a jail that can't resolve hostnames. It's resolv.conf is identical to the host machine's, but, whereas dns works fine on the host, when I try and look up addresses within the jail, they always fail. If I do a host -d, I get the following errors: ;; Querying server (# 1) address = 192.168.0.1 res_send: connect(dg) ([192.168.0.1].53): Invalid argument ;; Querying server (# 2) address = 192.168.0.2 res_send: connect(dg) ([192.168.0.2].53): Invalid argument res_nsend failed I can telnet from the jail to port 53 on the dns server, so it's not a routing issue -- a tcp connect seems to work, but not a udp one? My jail environment is set up in rc.conf as follows: jail_enable="YES" jail_socket_unixiproute_only="YES" jail_set_hostname_allow="NO" jail_list="webserver" jail_webserver_rootdir="/wwwroot" jail_webserver_hostname="vhost.ru.ac.za" jail_webserver_ip="192.168.1.7" jail_webserver_procfs_enable="NO" jail_webserver_devfs_enable="YES" jail_webserver_devfs_ruleset="4" The jail is running a world that was installed with the following options: DESTDIR=/wwwroot NO_FORTRAN=yes NO_GDB=yes NO_I4B=yes NO_IPFILTER=yes NO_TOOLCHAIN=yes NO_USB=yes NO_LPR=yes NO_ACPI=yes NO_VINUM=yes NOMAN=yes NO_SHAREDOCS=yes NO_X=yes NOGAMES=yes NOINFO=yes NOPROFILE=yes NOSHARE=yes PPP_NOSUID=yes NO_KERBEROS=yes NO_CVS=yes NO_CXX=yes it originally had NO_BIND=yes too, but I removed that in the vain hope it'd fix my problem. The same applies to jail_socket_unixiproute_only, which I've tried as "NO". The host system runs FreeBSD 5.2.1-RELEASE-p4 Any ideas would be appreciated, - Guy -- Systems Manager, IT Division, Rhodes University, Grahamstown, South Africa Email: G.Halse@ru.ac.za Web: http://mombe.org/ IRC: rm-rf@irc.zanet.net *** ANSI Standard Disclaimer *** J.A.P.H
