  • SSH connection times out

    - by mark
    Given: vm - a WinXPsp3 virtual machine hosted by a Win7sp1 physical machine alice is the user on vm srv - a Win2008R2sp1 server bob is the user on srv quake - a linux server mark is the user on quake Both vm and srv have the same new installation of cygwin (1.7.9) and openssh. Firewall service is disabled on vm (and its host) and on srv All the machines can be pinged from all the machines. ssh mark@quake works OK from both vm and srv. ssh bob@srv works OK from both quake and vm. ssh alice@vm works on the vm itself only, but it fails on the other two machines: alice@vm ~ $ ssh alice@vm alice@vm's password: Last login: Tue Oct 25 23:42:09 2011 from vm.shunra.net [mark@Quake ~]$ ssh -vvv alice@vm OpenSSH_4.3p2, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to vm [172.30.2.60] port 22. debug1: connect to address 172.30.2.60 port 22: Connection timed out ssh: connect to host vm port 22: Connection timed out bob@Srv ~ $ ssh -vvv alice@vm OpenSSH_5.9p1, OpenSSL 0.9.8r 8 Feb 2011 debug1: Reading configuration data /etc/ssh_config debug2: ssh_connect: needpriv 0 debug1: Connecting to vm [172.30.2.60] port 22. debug1: connect to address 172.30.2.60 port 22: Connection timed out ssh: connect to host vm port 22: Connection timed out I used ssh-host-config both on vm and srv to configure the ssh to run as a windows service. Besides that I did nothing else. Can anyone help me troubleshoot this issue? Thank you very much. EDIT The virtual machine software is VMWare Workstation 7.1.4. I think the problem is in its settings, but I have no idea where exactly. The Network Adapter is set to Bridged. EDIT2 All the machines are located in the company lab, I think all of them are on the same segment, but I may be wrong. Below is the ipconfig /all output for each machine (skipping the linux server). I have deleted the Tunnel adapters to keep the output minimal. If anyone thinks they matter, do tell so and I will post them as well. In addition ping output is given to show that DNS is correct. Something else, may be relevant, may be not. Doing psexec to srv works OK, whereas to vm failes with Access Denied. srv: C:\Windows\system32>ipconfig /all Windows IP Configuration Host Name . . . . . . . . . . . . : srv Primary Dns Suffix . . .

  • W7 routing - traffic not going to default gateway

    - by Ian Macintosh
    I have a really strange Windows 7 IPv4 routing issue that I can't get to the bottom of. The summary of the issue is that the default gateway is set to 192.168.254.253, but that it is actually using a default gateway of 192.168.254.254. Here's a network diagram: .-,( ),-. .-( )-. .-----( internet )----.--------------------------. | '-( ).-' | | | '-.( ).-' | | v v v .------------. .------. .------. | 10mb Fibre | | ADSL | | ADSL | '------------' '------' '------' | | | | | | v v v .---------------------. .--------------------. .--------------------. | Juniper Box | | Draytek DSL Router | | Draytek DSL Router | |---------------------| |--------------------| |--------------------| | (public IP address) | | 172.16.0.x | | 172.16.0.x | '---------------------' '--------------------' '--------------------' | | | | | .-------------------' | v v v .-------------------------. .-----------------. | Draytek Dual WAN Router | | Untangle GW | |-------------------------| |-----------------| | 192.168.254.254 | | 192.168.254.253 | '-------------------------' '-----------------' | | | | | v v =================================== LAN =================================== | | | | v v .----------------. .----------------. | Windows 7 W/S | | Windows 7 W/S | |----------------| |----------------| | 192.168.254.38 | | 192.168.254.77 | '----------------' '----------------' This is a recently (a few weeks ago) converted fibre site with the original 2 DSL lines still attached and running.

I've not inspected the traffic yet. In particular, I was going to look for ICMP redirects, though why there would be an ICMP redirect at all is not really sensible? .254 used to be the default gateway before the fibre was installed. Any ideas? Doesn't make sense to me why there should be this routing issue :( The Draytek Dual WAN Router was rebooted, the PC was rebooted. The PC had the network disabled and then re-enabled. All the standard stuff when Windows looses the plot. Hopefully somebody recognises the symptoms! PS: Sorry for the long post, but I didn't want to leave something potentially relevant out. PPS: No iSCSI involved on/at this or any other workstation so Windows 7 routing traffic through the gateway for local addresses isn't the issue.

  • Why from a virtualized Ubuntu system I can't discover the ip address of my router?

    - by AndreaNobili
    I am not into computer network and I have the following problem finding my router IP address. I have a Windows 8 PC on on which it is installed VmWare Workstation that virtualizes Linux Ubuntu. The network adapter settings of this Virtual Machine is setted as NAT. Now my problem is that if in the Windows 8 DOS shell I perform the ifconfig statment I obtain C:\Users\Andrea>ipconfig Configurazione IP di Windows Scheda Ethernet tap0: Stato supporto. . . . . . . . . . . . : Supporto disconnesso Suffisso DNS specifico per connessione: techub.lan Scheda Ethernet Connessione di rete Bluetooth: Stato supporto. . . . . . . . . . . . : Supporto disconnesso Suffisso DNS specifico per connessione: Scheda LAN wireless Connessione alla rete locale (LAN)* 11: Stato supporto. . . . . . . . . . . . : Supporto disconnesso Suffisso DNS specifico per connessione: Scheda LAN wireless Wi-Fi: Suffisso DNS specifico per connessione: DSL2750B Indirizzo IPv6 locale rispetto al collegamento . : fe80::89ff:6d12:49cf:4354%13 Indirizzo IPv4. . . . . . . . . . . . : 192.168.1.3 Subnet mask . . . . . . . . . . . . . : 255.255.255.0 Gateway predefinito . . . . . . . . . : 192.168.1.1 Scheda Ethernet Ethernet: Stato supporto. . . . . . . . . . . . : Supporto disconnesso Suffisso DNS specifico per connessione: Scheda Ethernet VMware Network Adapter VMnet1: Suffisso DNS specifico per connessione: Indirizzo IPv6 locale rispetto al collegamento . : fe80::edb3:8352:f954:2b0c%23 Indirizzo IPv4. . . . . . . . . . . . : 192.168.129.1 Subnet mask . . . . . . . . . . . . . : 255.255.255.0 Gateway predefinito . . . . . . . . . : Scheda Ethernet VMware Network Adapter VMnet8: Suffisso DNS specifico per connessione: Indirizzo IPv6 locale rispetto al collegamento . : fe80::d00b:8c6e:98b:f1ec%24 Indirizzo IPv4. . . . . . . . . . . . : 192.168.15.1 Subnet mask . . . . . . . . . . . . . : 255.255.255.0 Gateway predefinito . . . . . . . . . : Scheda Tunnel Teredo Tunneling Pseudo-Interface: Stato supporto. . . . . . . . . . . . : Supporto disconnesso Suffisso DNS specifico per connessione: Scheda Tunnel isatap.techub.lan: Stato supporto. . . . . . . . . . . . : Supporto disconnesso Suffisso DNS specifico per connessione: techub.lan Scheda Tunnel isatap.{5B95051D-79AB-4147-92CF-3A2E16698432}: Stato supporto. . . . . . . . . . . . : Supporto disconnesso Suffisso DNS specifico per connessione: Scheda Tunnel isatap.{340A5FAD-1597-402E-B658-29C37E8F7BC2}: Stato supporto. . . . . . . . . . . . : Supporto disconnesso Suffisso DNS specifico per connessione: Scheda Tunnel isatap.DSL2750B: Suffisso DNS specifico per connessione: DSL2750B Indirizzo IPv6 locale rispetto al collegamento . : fe80::5efe:192.168.1.3%26 Gateway predefinito . . . . . . . . . : So, looking at the previous output it appear clear that the default gateway (my router) is: 192.168.1.1, infact if I open it into a browser it apear to me the login mask to enter in the router settings.... Ok, if now I open the virtualized Ubuntu shell and perform the route command I obtain this output: andrea@andrea-virtual-machine:~$ route Tabella di routing IP del kernel Destination Gateway Genmask Flags Metric Ref Use Iface default 192.168.15.2 0.0.0.0 UG 0 0 0 eth0 link-local * 255.255.0.0 U 1000 0 0 eth0 192.168.15.0 * 255.255.255.0 U 1 0 0 eth0 So, here it say to me that the default gateway is 192.168.15.2 (that is not my router ip address), why? My idea is that it could depend by the NAT. Because my Windows system is connected using the wireless but in the virtualized Ubuntu I see that I am connected to a "wired network". So I think that the NAT virtualize a network adapter (or something like this) and that 192.168.15.2 could be the ip address of this network adapter... But it seems strange to me because, as you can see in the previous ipconfig output the VmWare network adapter addresses are: 192.168.129.1 and 192.168.15.1. So I have also 2 others doubts: 1) What device represents the 192.168.15.2 ip address that the virtualized Ubuntu see as Default gateway but that is not my router? 2) What exactly do the two VmWare network adapter that I have configured into my Windows 8 system? There is a way to discover my router ip from the virtualized Ubuntu system ? Tnx Andrea

  • OS X won't see Windows 7 in network (and vice versa)

    - by meds
    I've enabled SMB sharing in OS X Lion and have added folders to share, it says 'Windows Sharing: On' with a green circle next to it (from the sharing window) and that to access the volume I will need to to go to \\192.168.0.17. It also says that the OS X should be visible as 'macbook' in the network. Both my WIndows 7 and OS X are connected to the same network, yet when I try to go to \\192.168.0.17 or from the Mac try to go to my Windows system (smb://192.168.0.6) the two OSs don't see each other. Any ideas why? Attempting to ping the Mac from Windows results in this output in the command prompt: Pinging 192.168.0.17 with 32 bytes of data: Reply from 192.168.0.6: Destination host unreachable.

  • BIND returns serverfail when querying for its authoriative domain

    - by estol
    Hi there Serverfault folks! First of all: sorry about the title, I had some problem coming up with the proper title. I have a little home server set up, for internet sharing, samba, basic http, dlna mediaserver and what not, and I happend to have a domain at hand, so I thought why not direct it to this computer? I have a BIND 9.8.0 installed, and - afaik - configured it properly. For a few days, the public view did not worked, and I really did not cared, since the local view worked. But now suddenly, even the local view fails. If I try to query the nameserver for anything in my domain, it returns the following error: $ nslookup andromeda.dafaces.com ;; Got SERVFAIL reply from ::1, trying next server ;; Got SERVFAIL reply from ::1, trying next server Server: 127.0.0.1 Address: 127.0.0.1#53 ** server can't find andromeda.dafaces.com.dafaces.com: SERVFAIL Also, the public view points to the old ip address of the domain, probably because of the same error. Some information about the system: $ uname -a Linux tressis 2.6.37-ARCH #1 SMP PREEMPT Tue Mar 15 09:21:17 CET 2011 x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 5000+ AuthenticAMD GNU/Linux $ named -v BIND 9.8.0 And the named.conf file: # cat /etc/named.conf // // /etc/named.conf // include "/etc/rndc.key"; #controls { # inet 127.0.0.1 allow {localhost; } keys { "dnskulcs"; }; #}; options { directory "/var/named"; pid-file "/var/run/named/named.pid"; auth-nxdomain yes; datasize default; // Uncomment these to enable IPv6 connections support // IPv4 will still work: listen-on-v6 { any; }; listen-on { any; }; // Add this for no IPv4: // listen-on { none; }; // Default security settings. // allow-recursion { 127.0.0.1; ::1; 192.168.1.0/24; }; // allow-recursion { any; }; allow-query { any; }; allow-transfer { 127.0.0.1; ::1; 92.243.14.172; 87.98.164.164; 88.191.64.64; }; allow-update { key "dnskulcs"; }; version none; hostname none; server-id none; zone-statistics yes; forwarders { 213.46.246.53; 213.26.246.54; 8.8.8.8; 8.8.4.4; 192.188.242.65; 193.227.196.3; 2001:470:20::2; }; }; view "local" { match-clients { 192.168.1.0/24; 127.0.0.1; ::1; fec0:0:0:ffff::/64; }; recursion yes; zone "localhost" IN { type master; file "localhost.zone"; allow-transfer { any; }; }; zone "0.0.127.in-addr.arpa" IN { type master; file "127.0.0.zone"; allow-transfer { any; }; }; zone "."

    What's the best practise to store IP's with PHP in MySQL database? There's a function called ip2long - but this is just for IPv4. But what about IPv6? I know a php function that is for IPv6 IP's, but it doesn't work on Windows with PHP < Version 5.3

  • Howto check if two hosts are the same

    - by Michael Stoll
    Hi, I just came across an issue, where I had to check if a path points into a windows share. Part of this problem is to check if host A is the same as host B. Where host A and host B can be one of the following {IPv4-Address, IPv6-Address, Hostname, FQDN}. As I do not need to be exact it's enough to resolve and compare the IP-Addresses in my case. But is there, theoretically, a method to check if the hosts are the same?

  • Wifi not working after a few minutes

    - by drtanz
    I'm using a few MacBooks and iPads connected to a router via WiFi. The problem is that a few minutes after they connect via WiFi the connection stops working. This happens on all devices. I went into the router settings by connecting via cable and everything seems in order. Connecting a laptop via cable to the router I can use internet as normal, the problem is only with WiFi. What can be the problem here?

  • Centos/OVH: public IP on KVM virtual machine

    - by Sébastien
    Since a few days, I'm trying to configure my KVM vm to have a public IP address, without any success. First, I'm on OVH, and you need to know they don't allow networking from different mac addresses. I have so registered a virtual mac address associated with my failover IP Here's my configuration: Guest wanted IP: 46.105.40.x Host IP: 176.31.240.x Host configuration dummy0 interface: ifcfg-dummy0 BOOTPROTO=static IPADDR=10.0.0.1 NETMASK=255.0.0.0 ONBOOT=yes NM_CONTROLLED=no ARP=yes BRIDGE=br0 br0 bridge: ifcfg-br0 DEVICE=br0 TYPE=Bridge DELAY=0 ONBOOT=yes BOOTPROTO=static IPADDR=192.168.1.1 NETMASK=255.255.255.0 PEERDNS=yes NM_CONTROLLED=no ARP=yes Failover ip is redirected to the br0 bridge with ip route add 46.105.40.xxx dev br0 > cat /proc/sys/net/ipv4/ip_forward 1 > cat /proc/sys/net/ipv4/conf/vnet0/proxy_arp 1 > route -n Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 176.31.240.254 0.0.0.0 UG 0 0 0 eth0 46.105.40.x 0.0.0.0 255.255.255.255 UH 0 0 0 br0 176.31.240.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 br0 Guest configuration: KVM: <interface type='bridge'> <mac address='02:00:00:30:22:05'/> <source bridge='br0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </interface> I've borrowed most of the OVH configuration here (in french, http://guides.ovh.com/BridgeClient) for the guest configuration eth0 interface: ifcfg-eth0 DEVICE="eth0" BOOTPROTO=none HWADDR="02:00:00:30:22:05" NM_CONTROLLED="yes" ONBOOT="yes" TYPE="Ethernet" UUID="e9138469-0d81-4ee6-b5ab-de0d7d17d1c8" USERCTL=no PEERDNS=yes IPADDR=46.105.40.xxx NETMASK=255.255.255.255 GATEWAY=176.31.240.254 ARP=yes For the routes, I have in route-eth0: 176.31.240.254 dev eth0 default via 176.31.240.254 dev eth0 With this configuration, I don't have any access to the internet. The only thing I can do is to ping the public ip of the host, nothing more. My final conclusion is that the route does not work, because, when, on the guest, I run ping 8.8.8.8, I have, on the host: > tcpdump -i vnet0 icmp tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on br0, link-type EN10MB (Ethernet), capture size 65535 bytes 13:38:09.009324 IP 46-105-40-xxx.kimsufi.com > google-public-dns-a.google.com: ICMP echo request, id 50183, seq 1, length 64 13:38:09.815344 IP 46-105-40-xxx.kimsufi.com > google-public-dns-a.google.com: ICMP echo request, id 50183, seq 2, length 64 I never get the ping reply, only the request. It seems Guest - Host communication is fine. On eth0: > tcpdump -i eth0 icmp tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 13:39:40.240561 IP 46-105-40-xxx.kimsufi.com > google-public-dns-a.google.com: ICMP echo request, id 50439, seq 1, length 64 13:39:40.250161 IP google-public-dns-a.google.com > 46-105-40-xxx.kimsufi.com: ICMP echo reply, id 50439, seq 1, length 64 I have the request and the reply on eth0, but reply is not forwarded to the bridge. I really don't understand why, I though it was the aim of the route to do that! IPtables is disabled on both host and guest. I really hope some of you will be able to help me! Many thanks in advance, Sébastien

  • rsyslogd not monitoring all files

    So.. I've installed Logstash, and instead of using the logstash shipper (because it needs the JVM and is generally massive), I'm using rsyslogd with the following configuration. # Use traditional timestamp format $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat $IncludeConfig /etc/rsyslog.d/*.conf # Provides kernel logging support (previously done by rklogd) $ModLoad imklog # Provides support for local system logging (e.g. via logger command) $ModLoad imuxsock # Log all kernel messages to the console. # Logging much else clutters up the screen. #kern.* /dev/console # Log anything (except mail) of level info or higher. # Don't log private authentication messages! *.info;mail.none;authpriv.none;cron.none;local6.none /var/log/messages # The authpriv file has restricted access. authpriv.* /var/log/secure # Log all the mail messages in one place. mail.* -/var/log/maillog # Log cron stuff cron.* /var/log/cron # Everybody gets emergency messages *.emerg * # Save news errors of level crit and higher in a special file. uucp,news.crit /var/log/spooler # Save boot messages also to boot.log local7.* /var/log/boot.log In /etc/rsyslog.d/logstash.conf there are 28 file monitor blocks using imfile $ModLoad imfile # Load the imfile input module $ModLoad imklog # for reading kernel log messages $ModLoad imuxsock # for reading local syslog messages $InputFileName /var/log/rabbitmq/startup_err $InputFileTag rmq-err: $InputFileStateFile state-rmq-err $InputFileFacility local6 $InputRunFileMonitor .... $InputFileName /var/log/some.other.custom.log $InputFileTag cust-log: $InputFileStateFile state-cust-log $InputFileFacility local6 $InputRunFileMonitor .... *.* @@10.90.0.110:5514 There are 28 InputFileMonitor blocks, each monitoring a different custom application logfile..

How can I fix this so that all the files are monitored?

  • http request via iptables --to-destination ip redirect results in no response

    - by Wouter Vegter
    I have two Ubuntu servers with each having their own ip addresses. Let's call them server1 and server2, having respectively ip 1.1.1.1 and 2.2.2.2 I have a nginx running on server2. The sole purpose I want server1 to have is to redirect all incoming http (so port 80) requests to server2 without clients noticing that their request is being redirected. I tried the following command on server1: iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination 2.2.2.2 But when I enter 1.1.1.1 in my browser I get no respond: the page keeps trying to load without giving any message or error message (I get a time-out after 2-3 mins). But when I do remove the above iptables rule I immediately do get a "page not found error" when I enter 1.1.1.1 in my browser; so something is working but not as it should: when I enter 1.1.1.1 I want the html page to load that is hosted on 2.2.2.2 Because when i enter 2.2.2.2 in my browser I do see the webpage loaded. Could anyone please help me with this? I am searching quite some time (on severfault & Google) on this now so that's why I ask. Many thanks for reading my question! Update: Thank you all for you information. Unfortunately I still get no response I have the following iptables configuration: root@ip-10-48-238-216:/home/ubuntu# sudo iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination root@ip-10-48-238-216:/home/ubuntu# sudo iptables -t nat -L Chain PREROUTING (policy ACCEPT) target prot opt source destination DNAT tcp -- anywhere anywhere tcp dpt:www to:2.2.2.2 Chain OUTPUT (policy ACCEPT) target prot opt source destination Chain POSTROUTING (policy ACCEPT) target prot opt source destination When i run tcpdump and do request via chrome to 1.1.1.1 i get the following root@ip-10-48-238-216:/home/ubuntu# sudo tcpdump -i eth0 port 80 -vv tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 13:56:18.346625 IP (tos 0x0, ttl 52, id 12055, offset 0, flags [DF], proto TCP (6), length 60) 212-123-161-112.ip.telfort.nl.16386 ip-10-48-238-216.eu-west-1.compute.internal.www: Flags [S], cksum 0xb398 (correct), seq 2639758575, win 5840, options [mss 1460,sackOK,TS val 1223672 ecr 0,nop,wscale 6], length 0 13:56:18.346662 IP (tos 0x0, ttl 51, id 12055, offset 0, flags [DF], proto TCP (6), length 60) 212-123-161-112.ip.telfort.nl.16386 ww1dc1.shopreme.com.www: Flags [S], cksum 0x9ee0 (correct), seq 2639758575, win 5840, options [mss 1460,sackOK,TS val 1223672 ecr 0,nop,wscale 6], length 0 13:56:18.598747 IP (tos 0x0, ttl 52, id 10138, offset 0, flags [DF], proto TCP (6), length 60) 212-123-161-112.ip.telfort.nl.16387 ip-10-48-238-216.eu-west-1.compute.internal.www: Flags [S], cksum 0xac40 (correct), seq 2645658541, win 5840, options [mss 1460,sackOK,TS val 1223735 ecr 0,nop,wscale 6], length 0 13:56:18.598777 IP (tos 0x0, ttl 51, id 10138, offset 0, flags [DF], proto TCP (6), length 60) 212-123-161-112.ip.telfort.nl.16387 ww1dc1.shopreme.com.www: Flags [S], cksum 0x9788 (correct), seq 2645658541, win 5840, options [mss 1460,sackOK,TS val 1223735 ecr 0,nop,wscale 6], length 0 ^C 4 packets captured 4 packets received by filter 0 packets dropped by kernel the mentioned address relate to the following 212-123-161-112.ip.telfort.nl.16386 : my personal computer ww1dc1.shopreme.com.www : dns of server2 (2.2.2.2) ip-10-48-238-216.eu-west-1.compute.internal.www : amazon web services ec2 internal address of server1 (1.1.1.1) However, the tcpdump log on server2 (2.2.2.2) stays empty and I get no response back in my browser. I am able to ping from server1 to server2. And net.ipv4.ip_forward is set to 1 and so is /proc/sys/net/ipv4/ip_forward Could there be anything else that is missing?

  • Win 7 Netbook refuses to ping JetDirect card (all other PCs work)

  • OpenVPN on Tomato and Vista - can't see my network

    - by Ian
    I followed the instructions here (http://todayguesswhat.blogspot.ca/2011/03/quick-simple-vpn-setup-guide-using.html) to set up a TCP connection to OpenVPN on my Tomato router. Used TCP because the place I usually surf at seems to have the other ports blocked. My Vista laptop is able to connect to the router but I don't appear to be getting an IP address. I'm able to access my router's admin page, but I can't see the network at home. When I browse to Whatsmyip I see my home IP. Here are the results of route print -4 when I'm just connect to the library and when I've fired up the VP connection as well: Library only: =========================================================================== Interface List 22 ...00 ff c4 a0 e7 5c ......

  • Static route works on one computer, not the other

    - by Dan
    I have been struggling with this for a couple days now, maybe I just need some people with a fresh perspective to figure out what the issue is. Basically I have a bunch of computers that are being routed through a specific gateway in order to access a web page that is hosted internally on a separate subnet. I set up static routes on all of the computers, and they all work... except one. Here's what a route print -4 looks like for a working computer (Windows 7): =========================================================================== Interface List 14...xx xx xx xx xx xx ......Broadcom 802.11n Network Adapter 11...xx xx xx xx xx xx ......Realtek PCIe GBE Family Controller 1...........................Software Loopback Interface 1 12...00 00 00 00 00 00 00 e0 Microsoft ISATAP Adapter 13...00 00 00 00 00 00 00 e0 Microsoft 6to4 Adapter 17...00 00 00 00 00 00 00 e0 Teredo Tunneling Pseudo-Interface =========================================================================== IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 10.xxx.xxx.230 10.xxx.xxx.94 20 10.zzz.zzz.0 255.255.255.0 10.xxx.xxx.147 10.xxx.xxx.94 21 10.xxx.xxx.0 255.255.255.0 On-link 10.xxx.xxx.94 276 10.xxx.xxx.94 255.255.255.255 On-link 10.xxx.xxx.94 276 10.xxx.xxx.255 255.255.255.255 On-link 10.xxx.xxx.94 276 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 224.0.0.0 240.0.0.0 On-link 127.0.0.1 306 224.0.0.0 240.0.0.0 On-link 10.xxx.xxx.94 276 255.255.255.255 255.255.255.255 On-link 127.0.0.1 306 255.255.255.255 255.255.255.255 On-link 10.xxx.xxx.94 276 =========================================================================== Persistent Routes: Network Address Netmask Gateway Address Metric 10.zzz.zzz.0 255.255.255.0 10.xxx.xxx.147 1 =========================================================================== And here's a route print -4 from the station that doesn't work (also Windows 7): =========================================================================== Interface List 10...xx xx xx xx xx xx ......Realtek PCIe GBE Family Controller 1...........................Software Loopback Interface 1 12...00 00 00 00 00 00 00 e0 Microsoft 6to4 Adapter 14...00 00 00 00 00 00 00 e0 Microsoft ISATAP Adapter #2 16...00 00 00 00 00 00 00 e0 Teredo Tunneling Pseudo-Interface =========================================================================== IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 10.xxx.xxx.230 10.xxx.xxx.132 276 10.zzz.zzz.0 255.255.255.0 10.xxx.xxx.147 10.xxx.xxx.132 21 10.xxx.xxx.0 255.255.255.0 On-link 10.xxx.xxx.132 276 10.xxx.xxx.132 255.255.255.255 On-link 10.xxx.xxx.132 276 10.xxx.xxx.255 255.255.255.255 On-link 10.xxx.xxx.132 276 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 224.0.0.0 240.0.0.0 On-link 127.0.0.1 306 224.0.0.0 240.0.0.0 On-link 10.xxx.xxx.132 276 255.255.255.255 255.255.255.255 On-link 127.0.0.1 306 255.255.255.255 255.255.255.255 On-link 10.xxx.xxx.132 276 =========================================================================== Persistent Routes: Network Address Netmask Gateway Address Metric 10.zzz.zzz.0 255.255.255.0 10.xxx.xxx.147 1 =========================================================================== Both of these stations are running Windows 7.

This is the intended behavior, and again it is working everywhere but that one station. I noticed that the Active Route metric costs differ between the two stations, but I am new to the routing table and I am not sure how that is impacting the behavior. I hope I have been able to explain the situation clearly. Any help would be much appreciated. I can provide any additional information if needed!

  • obtaining nimbuzz server certificate for nmdecrypt expert in NetMon

    - by lurscher
    I'm using Network Monitor 3.4 with the nmdecrypt expert. I'm opening a nimbuzz conversation node in the conversation window and i click Expert- nmDecrpt - run Expert that shows up a window where i have to add the server certificate. I am not sure how to retrieve the server certificate for nimbuzz XMPP chat service. Any idea how to do this? this question is a follow up question of this one. Edit for some background so it might be that this is encrypted with the server pubkey and i cannot retrieve the message, unless i debug the native binary and try to intercept the encryption code. I have a test client (using agsXMPP) that is able to connect with nimbuzz with no problems. the only thing that is not working is adding invisible mode. It seems this is some packet sent from the official client during login which i want to obtain. any suggestions to try to grab this info would be greatly appreciated. Maybe i should get myself (and learn) IDA pro?

Is there any way to fix this? Note my router is on an IPv6 network (m-net), with IPv4 only through DS-Lite. I'm not sure whether this affects anything. Update: Following the guide here (putting myusername instead of MY-DIRECT-URL-KEY) hasn't given any succes. However, the status field has changed slightly: Dynamic DNS: activated, mydomain.crabdance.com, Status: unknown
