• Multicast accross the subnets

  - by Hasan Khan

  My application sends some UDP packets on a multicast address. In our office we have 3 subnets connected via routers. Sitting in my subnet I'm able to ping the IP of the other subnet. Will multicast packets cross my subnet and reach the machines of other subnets? Or router will need some configuration? Or do I have to program a bridge for it? Please note that I do not know anything about Networking. Kindly tell me something that I can ask my network admin to do.

• Proxmox 31 + KVM routing + IP subnet + csf

  - by KeyJey

  We have proxmox 3.1 server in netzner with routuing network and IP subnet block. We want to implement csf firewall without interfering the traffic of the KVM VMs, what would be the easiest way? We readed that we should add this lines to /etc/csf/csfpost.sh: iptables -A FORWARD -d 144.76.223.155 -j ACCEPT iptables -A FORWARD -d 144.76.223.156 -j ACCEPT iptables -A FORWARD -d 144.76.223.157 -j ACCEPT iptables -A FORWARD -d 144.76.223.158 -j ACCEPT iptables -A FORWARD -d 144.76.223.159 -j ACCEPT iptables -A FORWARD -d 144.99.183.323 -j ACCEPT But when we enable csf the ping breaks, this is the network config (IPs are modified): auto lo iface lo inet loopback # device: eth0 auto eth0 iface eth0 inet static address 144.76.166.100 netmask 255.255.255.255 pointopoint 144.76.183.97 gateway 144.76.183.97 # for single IPs auto vmbr0 iface vmbr0 inet static address 144.76.166.100 netmask 255.255.255.255 bridge_ports none bridge_stp off bridge_fd 0 up ip route add 144.99.183.323/32 dev vmbr0 # for a subnet auto vmbr1 iface vmbr1 inet static address 144.76.166.100 netmask 255.255.255.248 bridge_ports none bridge_stp off bridge_fd 0 Thanks in advanced ! :)

• Can't communicate with Primary DNS Server

  - by horsley

  A computer, with Windows 7, can't access any website by domain suddenly. Whether this computer use a wired link or connect to the WLAN, The fault persists IP and DNS obtained automatically, and seems normal (ipconfig /all return the correct info) I can visit websites by using HTTP proxy The DNS server is available, other computer in my room works properly. I can ping myself, the gateway and any other IP, but domains I can use nslookup and obtain the correct IP info There are some error information in the event log about dns client events explaining the client can not verify the DNS server available Windows network diagnosis explain that Windows can't communicate with the device or resource (Primary DNS Server) I guess the dns client should be blame. I tried to do the following things but the fault persist. Reinstall the driver of network adapter Reset TCP/IP (netsh int ip reset) Reset Winsock (netsh winsock reset) Reset LSP I don't want to reinstall the whole os, what should I do?

• Need IPSec help on Windows 2003

  - by user37456

  Hey guys, I am trying to configure IPSec between a web and app server in our environment. I want all traffic between these two servers to use IPsec and be encrypted. These servers are on the same domain so i am currently using Kerebos for security, I have also tried pre-defined keys and nothing changed. When I try and ping between the servers I get "Negotiating IP Security" everytime. I have also confirmed that when I change "Require Security" to "Permit" everything works so IPSec is working, I believe its something with my security setup. Under the security tab both servers have the default 3DES keys first and then DES keys. I have also specified tunnel endpoints (the alternate server's IP). What am I missing? Thanks for any help..

• Unknown protocol when trying to connect to remote host with stunnel

  - by RaYell

  I'm trying to set up a stunnel for WebDav on Windows. I want to connect 80 port on my local interface to 443 on another machine in my network. I can ping the machine remote machine. However when I use the tunnel, I'm getting this error all the time SSL state (accept): before/accept initialization SSL_accept: 140760FC: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol There is nothing in the logs on the other machine and here's my stunnel connection config [https] accept = 127.0.0.2:80 connect = 10.0.0.60:443 verify = 0 I've set it up to accept all certificates so this shouldn't be a problem with a self-signed certificate remote host uses. Does anyone knows what might be the problem that this connection cannot be eastablished?

• VPN Error 868 when connecting even if using IP address

  - by Fr33dan

  I am trying to connect to a public VPN from VPNGate. However when I attempt to connect to a VPN from the list using MS-SSTP protocol I get the following error: Error 868: The remote connection was not made because the name of the remote access server did not resolve. If I open a command prompt and ping the address in question it resolves to the IP shown on the listing. If I configure the VPN using that IP address directly I still receive the error even though the name no longer needs to resolve. This was working yesterday but it seems the VPN I was using has been removed from the list. What is happening and how can I fix it?

• Hostname problems in CentOS 5.5

  - by spoon16

  I just set up a CentOS 5.5 machine on my local network and attempted to modify the hostname by editing /etc/sysconfig/network file. When I'm logged in locally the change to the hostname is reflected and seems to be working fine. When I open a SSH session via PuTTY from Windows this is what I see at the prompt: [root@? ~]# cat /etc/sysconfig/network NETWORKING=yes NETWORKING_IPV6=yes HOSTNAME=mini.local [root@? ~]# sysctl kernel.hostname kernel.hostname = ? [root@? ~]# hostname ? [root@? ~]# hostname -f hostname: Unknown server error A couple of other symptoms that may be helpful in troubleshooting this problem. I can ping the CentOS box from my Windows machine via IP but not hostname. Also, my Netgear router does not display the hostname when I view the "Connected Devices", I do see the mac address and the proper IP listed though. How can I make it so that the hostname is properly propagated throughout my network?

• Mac OS X Snow Leopard: permissions changed on /var results in dns lookup issues

  - by Ivan

  I was attempting to solve an issue ("/var/log/msmtp.log: permissions denied" error when attempting to send mail using msmtp) when I did this: > chmod -R 770 /var After that, my machine would not resolve domain names via cURL. (ping also fails) But, oddly, I can enter domain names into Safari and visit any web pages w/o a problem... I'm actually not sure if the chmod command is the cause of the problem, but I suspect it is. Also, if I ls -l on /var (or /private/var) it doesn't seem that any of the subdirectories or files there actually changed permission, but there are many, so I can't say that conclusively... Incidentally, I fixed the original error (msmtp.log permission denied) by setting TMPDIR=/tmp in my local environment (bash). Now the error goes away, but I get this error: msmtp: cannot locate host domainname.org: nodename nor servname provided, or not known Any ideas about how to go about getting DNS working again?

• DNS and RPC Unavailable

  - by Berek Bryan

  I have a server that is host a MSSQL database and some other server related tasks. The server communicaties with a large number of devices. The devices send data to the server. The communication links are down between the devices on the intranet and to the outside world. However it seems I can ping and can be pinged from machines on the same switch. This includes the DNS Servers. When I run, C:\ipconfig /registerdns I get RPC Server is Unavailable. So, it seems that the server can not verify the DNS server. Both DNS server are up and running. No other machines are affected on the network.

• remote desktop to Fedora 20 with xrdp

  - by 5YrsLaterDBA

  I was able to setup xrdp on my Fedora 13 machine and access it from my Windows 7 machine by follow the steps on the first post on this thread It was simple and easy. But when i try the same on my Fefora 20 machine, things are quite different. There is no error message but some new info like these: # chkconfig --levels 35 xrdp on Note: Forwarding request to 'systemctl enable xrdp.service'. # service xrdp start Redirecting to /bin/systemctl start xrdp.service and then I cannot remote it from my window machine. I also did the following based on the last post of above threa: # yum -y install tigervnc-server Any configuration I should do to make xrdp works for me? I was able to ping each other. EDIT: I can access the shared folder on my Windows machine from my Fedora 20. It seems the problem is on the Fedora side. how to know the service on linux is running? The "service --status-all" cannot give me useful information.

• XP Mode as a server, Win 7 as a client

  - by Spyro

  I have two virtual machines (XP Mode). They are connected to each other by a network setting - Internal Network. It is the only working setting. This is the only way I got two virtual XP to ping each other. Now I want to connect each of them from the application that runs on Windows 7 which is hosting both virtual machines, but I can't do that. The firewall on both XP-Mode machines is disabled. Any other networking setting added as additional adapter on Xp-Mode machine does not allow me to connect from Windows 7. So my question is this - how to enable connection from Windows 7 application to XP mode application (client - server)? Point 2 (pass message) work perfectly because of the "internal network" setting. The problem is point 1 and 3.

• Forcing Remote machine to serve RDP (or similar) session

  - by sMaN

  Due to a Dell/Nvidia design flaw in the Dell Inspiron 1420 series, my laptop no longer shows a display. I am looking for a solution to view it remotely. I have used it via RDP in the past (not for a year though) however for what ever reason I can no longer RDP, it could have been disabled some how. However, I'm on the same LAN, I can ping it, and know its login creditials. Is there a way I can hack into it remotely to force it to serve a RDP session or an alternative? Please bear in mind my only view I could have to its interface is via a remote session. Its running Windows 7 Pro

• Force an LXC container to use its own IP address

  - by emma sculateur

  Sorry if this question has already been asked. I could not find it, I have this setup : +---------------------------------------------------------------------------------------------+ |HOST | | | | +-------------------------------------------------+ | | | UBUNTU-VM | | | | | | | | +-------------------+ | | | | |UBUNTU-LXC | | +------------------+ | | | | 10.0.0.3/24 | 10.0.0.1/24 | |OTHER VM | | | | | eth0-----lxcbr0----------eth0-----------br0----------eth0 | | | | | | 192.168.100.2/24| 192.168.100.1/24 |192.168.100.3/24 | | | | +-------------------+ | +------------------+ | | +-------------------------------------------------+ | +---------------------------------------------------------------------------------------------+ When I ping 192.168.100.3 from my UBUNTU-LXC, the source IP address is automatically changed to 192.168.100.2 by UBUNTU-VM. It's like having a NAT, whereas I really want my UBUNTU-LXC to talk with it own IP address. Is there any way to do this ? Edit : these info may be relevant : I am using KVM +libvirt to set up my VMs Here is how I create my interface in UBUNTU-VM : <interface type='bridge'> <mac address='52:54:00:cb:aa:74'/> <source bridge='br0'/> <model type='e1000'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/> </interface>

• Suddenly blocked from a site

  - by Diego Romero

  Suddenly from a time to now I haven't been able to go to a site I used to go frequently for maintenance (Wordpress). I tried different browsers, restarting my laptop, clearing cache, history, cookies. Also did a ping to the site ip, go 4 packets send and 4 lost. This is a problem I think with only my laptop, since I've been able to go into the site from other devices in the same network. I have also tried connecting to the same site from a completely different network with the same problem. I really don't know what to do about this, any advices? PS: site hosted in wp engine if that has anything to do with this problem.

• Strange DNS problem [seems to be IPv6 issue]

  - by Homer J. Simpson

  Hi, I'm experiencing strange problems with my Kubuntu 9.10 when doing DNS requests from various applications. The requests are extremely slow, so loading any pages in Firefox or Konqueror, doing package installations in Kpackagemanager and other apps is really painful, while for example Opera doesnt have any problems, and ping is normally fast as well for DNS pings. I checked the proxy settings of both the used applications as well as of the general system and there are none, so to me it doesn't seem as there was something inbetween.. Does anybody have an idea on what to check for possible problem sources or how to solve this ? I'm behind a DSL home router which does the DHCP (and works well with my other computer). Any kind of advice would be really helpful. Edit: It seems to be some kind of IPv6 problem, as I could get it to work by disabling IPv6 explicitly in Firefox. Is there a general solution to this ?

• Routing to a Terminal Services Cluster

  - by Dave

  I am trying to connect to a Load Balanced Windows 2008 R2 cluster using Remote Desktop Services. I have no trouble connecting to the the Servers' IP addresses (.253.16 and .253.17) or the Cluster address (.253.20) from inside the subnet (.253). The trouble is when I try to connect from the other subnet(.251). I can remote to the other non-clustered servers (.253.12 and .253.15) inside the .253 subnet from the .251 without an issue. I receive a ping reply from the cluster and other servers when I am on the .251 subnet. But when I try to connect via remote desktop it times out but only to any of the IPs on the cluster (.20,.17,.16). My ASA 5510 handling the routing reports message in the log: Deny TCP (no connection) from 192.168.251.2/4283 to 192.168.253.16/3389 flag FIN PSH ACK Here is a picture if it helps http://dl.dropbox.com/u/4217864/terminal%20server.jpg Thanks for any help

• Ubuntu server 9.10 freezes up after ~10 minutes

  - by Matt Williamson

  I just upgraded my Ubuntu server from 9.04 to 9.10 and after about 10 minutes it locks up. It won't respond to ping, can't ssh in and the terminal doesn't accept keyboard input. It does not have X installed. I then reformatted and installed it from scratch with the same results. There are two hard drives, the first is for the OS and the second is for media. The second has not changed, it is an ext3 formatted drive with one partition. I stopped random services (samba, ushare, transmission-daemon) to see if they were causing the issue, but it still locked up. I did a watch "dmesg|tail" until it locked up, but I didn't see anything. How can I troubleshoot this further? I don't want to downgrade. Machine specs: Dell Dimension 3000 Pentium 4 @3GHz 512M RAM

• Windows XP Does Not Follow CNAME Shares

  - by user49349

  I am supporting a mix of Windows XP Pro and Windows 7 desktops in my Active Directory network, and I am having an odd issue with XP and CNAME records. Say I have a record in my DNS for a server with an A name of something like STORAGE.company.local and give it a CNAME of NAS.company.local. I can go onto an XP and 7 computer, and ping NAS and it will automatically resolve to STORAGE.company.local. If I am on Windows 7 and go to run and enter \\STORAGE or \\NAS, it will go to that server in Explorer. If I do the same in XP, STORAGE will work but NAS will not. It just times out Is there some setting buried in XP to make this work properly?

• wi-fi connection drops periodically for a few seconds

  - by sergiom

  I've read the similar question on wireless connections dropping, but no answer seems to apply to my case I have configured the wi-fi lan of my router to broadcast sid and use WPA-PSK. Every few minutes my wi-fi connection drops for a few seconds and then restores. When I use two computers and run a ping -n 50000 on both computers, I see that the connection drops at different times but with almost the same rate. the router is a zyxel, one pc runs windws vista and uses a USB wi-fi device from Belkin: F6D4050 the other one runs windows 7 is a Dell PC with an Intel(R) WiFi Link 5100 AGN there are no other wi-fi lans around

• Ethernet switch not working

  - by Froskoy

  I've just tried using two different ethernet switches on my network to replace an 8-port Netgear gigabit ethernet switch, which works fine, but doesn't have enough ports for what I need. Computers are connected to a TP-Link TD-8840T router via a switch. They use DHCP for IP address assignment. One switch is a TigerSwitch 6924M, which I'd expect to be difficult to set up, since it is second hand and has an advanced configuration menu, which I can't access without a serial port. However, the second switch that I tried is a new TP-Link TL-SF024, which doesn't appear to have any configuration options, so that can't be the problem. When I say "not working," I mean that although they display that they are connected to a network, they cannot access the internet. For example commands like "ping -c10 google.co.uk" come up with 100% packet loss. What could be causing the problem and how do I fix it?

• KVM Guest not reachable from host

  - by Paul

  Hello, I'm running Ubuntu server 9.10, installed KVM etc. Created the bridge network following instructions on help.ubuntu.com/community/KVM/Networking Created a windows 2008 guest using virt-install command line (using virt-manager GUI from a remote Ubuntu desktop would not let me select the ISO location). I can however use a remote virt-manager to connect to the guest and complete the windows install. Within windows 2008 I changed the IP address but cannot ping from outside world. The bridge network appears fine - I'm not sure what else to look at! Here is the interfaces file: The loopback network interface auto lo iface lo inet loopback The primary network interface auto eth0 iface eth0 inet manual # auto br0 iface br0 inet static address 60.234.64.50 netmask 255.255.255.248 network 60.234.0.0 broadcast 60.234.0.255 gateway 60.234.64.49 bridge_ports eth0 bridge_stp off bridge_fd 0 bridge_maxwait 0 auto eth1 iface eth1 inet static address 192.168.12.2 netmask 255.255.255.0 broadcast 192.168.12.255 The ip of the windows server is 60.234.64.52 What else should I check? Regards Paul.

• How to tell Windows 7 to ignore a default gateway

  - by zildjohn01

  I currently have 2 network cards in my PC -- one connected to an internal network on a router with a disconnected WAN port (10.x.x.x), and one connected to the internet through a consumer router (192.168.0.x). Windows seems to recognize them correctly (my "Network and Sharing Center" lists them as "No Internet" and "Internet" respectively), however when I try browsing the internet it always tries the internal network's default gateway, rather than the one with internet access. Trying to ping a website results in "Reply from 10.0.0.1: Destination net unreachable.". A simple "route delete 0.0.0.0 mask 0.0.0.0 10.0.0.1" fixes the problems, but they return upon reboot, or upon renewing my IP. Is there any way to tell Windows to ignore one NIC's default gateway, or to at least give them priorities?

• Not working WEP key in Ubuntu

  - by stupid-idiot

  This time I've got some problem with connection to the internet from my old laptop with ubuntu, I already had some problems with setting up the radio on my network card but I think it works now since it finds some wireless networks. The problem is that I can't connect to my router via wi-fi even if I'm hundred-percently sure the wepkey I punch there is correct, it works via LAN though. Also, I'm not able to ping myself with 127.0.0.1. I'm sorry to say it but I don't think I can stand this shitness for much longer. Although it's much much faster than Windows it's useless since i can't download any libraries for development. If anyone has any experience with this, even indirect, please leave your answer or comment thx

• WEB based HPC cluster node management

  - by Skuja

  Hello, i am working on my school diploma thesis. The main goal is to create web based application where logged users could see free and busy nodes, turn them on and off, see what process they are running etc. Figured out that i could do something like this - write some cron daemon that would run every 30seconds or so, and it could run ping utility for each node to find out if it is on or off, then write results to some file. Then from my web app (i will write in PHP) i could read the info. Will it be a good solution? How would you suggest me to do it? And finally, is there any existing solutions (it may not be a definetly ewb based) for managment of cluster nodes?
