I'm having a little trouble with my jail's networking and I'm not sure what to make of it. My jailhost has an IP of x.y.z.48, my test jail is x.y.z.49. The jailhost has both IP-adresses, the jail has just it's own: Jail# ifconfig bce0: flags=3D8843 metric 0 mtu 1500 =20 options=3D1bb ether xx:xx:xx:xx:xx:10 inet x.y.z.60 netmask 0xffffffc0 broadcast x.y.z.63 media: Ethernet autoselect (1000baseSX ) status: active [...] Host# ifconfig bce0: flags=3D8843 metric 0 mtu 1500 =20 options=3D1bb ether xx:xx:xx:xx:xx:10 inet x.y.z.61 netmask 0xffffffc0 broadcast x.y.z.63 inet x.y.z.60 netmask 0xffffffc0 broadcast x.y.z.63 media: Ethernet autoselect (1000baseSX ) status: active [...] I am able to access the ssh-server running on the jail, and I am able to access the proxyserver of our network via telnet and get some pages of the internet. However, if I want to install something from the ports, the jail is unable to fetch it: Jail# cd /usr/ports/ftp/wget Jail# make =3D=3D=3D> Vulnerability check disabled, database not found =3D=3D=3D> Found saved configuration for wget-1.11.4_1 =3D> wget-1.11.4.tar.bz2 doesn't seem to exist in /usr/ports/distfiles/. =3D> Attempting to fetch from http://ftp.gnu.org/gnu/wget/. fetch: http://ftp.gnu.org/gnu/wget/wget-1.11.4.tar.bz2: Operation timed out =3D> Attempting to fetch from ftp://ftp.gnu.org/gnu/wget/. [...] I've set the appropriate environment variables HTTP_PROXY, HTTPS_PROXY and FTP_PROXY. If I test the connection with netcat, I get the following error message: # nc -zvw 1 -x 'proxy.example.com:8080' www.freebsd.org 80 nc: read failed (0/3): Broken pipe The funny thing is, that I have no problem installing ports from the Host-system. From what I can tell, all the config files are correct: Jail# cat /etc/rc.conf sshd_enable=3D"YES" ifconfig_bce0=3D"inet x.y.z.60 netmask 255.255.255.192" defaultrouter=3D"x.y.z.62" hostname=3D"jail.example.com" Host# cat /etc/rc.conf sshd_enable=3D"NO" ifconfig_bce0=3D"inet x.y.z.61 netmask 255.255.255.192" defaultrouter=3D"x.y.z.62" hostname=3D"host.example.com" ipv6_enable=3D"NO" jail_enable=3D"YES" jail_set_hostname_allow=3D"NO" jail_list=3D"jail" jail_jail_hostname=3D"jail" jail_jail_ip=3D"x.y.z.60" jail_jail_rootdir=3D"my/jail/root" jail_jail_devfs_enable=3D"YES" Any ideas?
