One is working and the other is failing. This is probably a bug in the mirage tool, because you only created a single stack in your config.ml, but check the generated main.ml to see what it actually did... As a work-around, you could just pass the stack to your unikernel and have it create conduit and the resolver. > ARP: transmitting probe -> 10.0.20.1 > ARP: updating 10.0.20.1 -> 00:1b:d5:f4:1d:c4 > ARP: retrying 10.0.20.1 (n=2) > ARP: transmitting probe -> 10.0.20.1 > ARP: updating 10.0.20.1 -> 00:1b:d5:f4:1d:c4 > ARP: retrying 10.0.20.1 (n=3) > ARP: transmitting probe -> 10.0.20.1 > ARP: updating 10.0.20.1 -> 00:1b:d5:f4:1d:c4 > IP.output: arp timeout to gw 5.153.225.51 > Fatal error: exception > Ipv4.Make(Ethif)(Clock)(Time).Routing.No_route_to_destination_address(_) > Raised at file "src/core/lwt.ml", line 788, characters 22-23 > Called from file "lib/main.ml", line 58, characters 10-20 > Called from file "main.ml", line 107, characters 2-77 > Mirage exiting with status 2 > Do_exit called! > base is 0x46ff10 caller is 0x23e89d > base is 0x418df0 caller is 0x0 > base is 0x273c9b caller is 0x5241570000000000 > base is 0x65676172696d Page fault at linear address 656761726975, rip > 25a747, regs 000000000046fe28, sp 46fed0, our_sp 000000000046fdf0, code 0 > RIP: e030:[<000000000025a747>] > RSP: e02b:000000000046fed0 EFLAGS: 00010002 > RAX: 0000000000000017 RBX: 000065676172696d RCX: 00000000000004ba > RDX: 00000000000014bb RSI: 000000000046fd20 RDI: 0000000000000004 > RBP: 000000000046ff10 R08: 00000000000014bb R09: 0000000000000020 > R10: 0000000000000017 R11: 0000000000000010 R12: 0000000000000000 > R13: 0000000000000000 R14: 0000000000000000 R15: 0000000000000000 > base is 0x46ff10 caller is 0x23e89d > base is 0x418df0 caller is 0x0 > base is 0x273c9b caller is 0x5241570000000000 > base is 0x65676172696d Page fault in pagetable walk (access to invalid > memory?). > > > > On 29/05/15 04:06, Andrew Stuart wrote: > > Hello > > I am trying to run a static Mirage web server on a local Xen server. > > When I do > curl 192.168.1.111 > from dom0 it works fine. > > When I try to access 192.168.1.111 from any other device on the network I > get the errors below. > > The cfg file includes this: > vif = [ 'mac=c0:ff:ee:aa:ff:ee,bridge=xenbr0â ] > > I have also tried > vif = [ 'bridge=xenbr0â ] > > I have various other domu machines including an Ubuntu web server that have > no problem responding to network requests from other devices on the network. > > Any hints valued. > > > setting 0000000000000000-00000000001a4000 readonly > skipped 1000 > MM: Initialise page allocator for 43f000(43f000)-10000000(10000000) > MM: done > Demand map pfns at 10001000-0000002010001000. > Initialising timer interface > Initialising console ... done. > gnttab_table mapped at 0000000010001000. > getenv(OCAMLRUNPARAM) -> null > getenv(CAMLRUNPARAM) -> null > getenv(PATH) -> null > Unsupported function lseek called in Mini-OS kernel > Unsupported function lseek called in Mini-OS kernel > Unsupported function lseek called in Mini-OS kernel > getenv(OCAMLRUNPARAM) -> null > getenv(CAMLRUNPARAM) -> null > getenv(TMPDIR) -> null > getenv(TEMP) -> null > Netif: add resume hook > Netif.connect 0 > Netfront.create: id=0 domid=0 > MAC: 00:16:3e:5f:6c:04 > Attempt to open(/dev/urandom)! > Manager: connect > Manager: configuring > DHCP: start discovery > > Sending DHCP broadcast (length 552) > DHCP response: > input ciaddr 0.0.0.0 yiaddr 192.168.1.111 > siaddr 192.168.1.254 giaddr 0.0.0.0 > chaddr 00163e5f6c0400000000000000000000 sname file > DHCP: offer received: 192.168.1.111 > DHCP options: Offer : DNS servers(192.168.1.254), Routers(192.168.1.254), > Subnet mask(255.255.255.0), Lease time(43200), Server > identifer(192.168.1.254) > Sending DHCP broadcast (length 552) > DHCP response: > input ciaddr 0.0.0.0 yiaddr 192.168.1.111 > siaddr 192.168.1.254 giaddr 0.0.0.0 > chaddr 00163e5f6c0400000000000000000000 sname file > DHCP: offer received > IPv4: 192.168.1.111 > Netmask: 255.255.255.0 > Gateways: > [192.168.1.254] > sg:true gso_tcpv4:true rx_copy:true rx_flip:false smart_poll:false > ARP: sending gratuitous from 192.168.1.111 > DHCP offer received and bound to 192.168.1.111 nm 255.255.255.0 gw > [192.168.1.254] > Manager: configuration done > ARP: transmitting probe -> 192.168.1.254 > ARP: updating 192.168.1.254 -> 00:04:ed:b2:9d:0e > ARP responding to: who-has 192.168.1.111?
