[Xen-users] Can not establish a SSH Connection into Dom0
Hello everyone, I own a small network: Three ''normal'' Computers (Win or Debian) and a Xen 3.02 (Debian) installation with three DomU''s. SSH between the Computers works fine with one exception: I can establish a SSH connection from the DomU to the ''normal'' Computers and to Dom0 but I can not establish a SSH connection from Dom0 (or from a ''normal computer'') INTO DomU. It is also not possible to establish a SSH connection between the DomU''s I searched a lot, modified my Xen several time but still have no idea where the problem could be. When I try to connect with SSH to a DomU the message alway is: "Read from socket failed: Connection reset by peer" I run some services on the DomU''s: At the moment a Samba server and a VPN Server and all services are working fine. Then I reinstalled the SSH several times, everytime with deleting /root/.ssh/ and /etc/ssh/. For my DomU''s I use the following mac adresses: AA:00:00:00:00:20, AA:00:00:00:00:21 and AA:00:00:00:00:22. I also tried to run the DomU''s with random macadresses like 00:16:3E:4E:76:E5. At last, I installed another ethernetcard into my computer, hide the ethernetcard from Dom0 and used it with its real macadress in a DomU and told SSHd to listen on this card. Nothing helps. My entry in the xend-config.sxp is: (xend-relocation-server yes) (xend-relocation-hosts-allow ''^localhost$'') (network-script network-bridge) (vif-script vif-bridge) (dom0-min-mem 196) (dom0-cpus 0) ''brctl show'' shows me: bridge name bridge id STP enabled interfaces xenbr0 8000.feffffffffff no peth0 vif0.0 vif1.0 vif1.1 vif2.0 vif3.0 and a ifconfig in Dom0 shows me: eth0 Link encap:Ethernet HWaddr 00:04:AC:B8:88:27 inet addr:192.168.100.4 Bcast:192.168.100.255 Mask:255.255.255.0 inet6 addr: fe80::204:acff:feb8:8827/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:6113 errors:0 dropped:0 overruns:0 frame:0 TX packets:4281 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:565494 (552.2 KiB) TX bytes:701876 (685.4 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) peth0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:6497 errors:0 dropped:0 overruns:0 frame:0 TX packets:5126 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:614137 (599.7 KiB) TX bytes:787386 (768.9 KiB) Interrupt:16 Base address:0x2080 vif1.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:92 errors:0 dropped:0 overruns:0 frame:0 TX packets:1266 errors:0 dropped:25 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:6464 (6.3 KiB) TX bytes:130097 (127.0 KiB) vif1.1 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:1276 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) vif2.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:631 errors:0 dropped:0 overruns:0 frame:0 TX packets:1534 errors:0 dropped:29 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:70109 (68.4 KiB) TX bytes:165655 (161.7 KiB) vif3.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:189 errors:0 dropped:0 overruns:0 frame:0 TX packets:1360 errors:0 dropped:46 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:18047 (17.6 KiB) TX bytes:143611 (140.2 KiB) xenbr0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1255 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:110734 (108.1 KiB) TX bytes:468 (468.0 b) Has anyone an idea, what should I modify as next? The computer, on which Xen is running, is an old IBM Netfinity with 2GB Ram and and some Ethernetcards. Thank you in advance for every Tip, -- Bis zu 70% Ihrer Onlinekosten sparen: GMX SmartSurfer!
