100.0.0.0/8 was a allocated to ARIN. ARIN has allocated one quarter of this to be used as shared address space. The other three quarters have been allocated to various providers including T-Mobile, Verizon, Sprint, Wayport. 100.64.0.0/10 is shared address space to be used similarly to RFC1918 address space. The most significant difference is that you are ...

You get the same assurance as everyone else who has an IP address. If Azure has spare IP addresses it can use them internally or externally as it pleases, there is no requirement to use RFC1918 addressing internally.

I figured out what my problem was and I'm posting it here should anyone runs into a similar issue. In my Xen config I did not put in a MAC address. IE I had: vif = [ 'bridge=xenbr0', 'bridge=xenbr1' ] When I needed something like: vif = [ 'bridge=xenbr0', 'mac=00:11:5e:5n:2c:1c,bridge=xenbr1' ] The routing for the MAC address didn't expire right away ...

ssh user234@192.168.10.20 or the hostname more options like port number ssh -p 10245 root@box listening socket on the destination (very cool) ssh -g -L8022:another_ip:22 user@primary_ip then in another shell you can ssh to another_ip through the primary_ip on port 8022 ssh -p 8022 user@primary_ip

ssh'ing to a VM is no different than ssh'ing to any other system on the network. Log into one of the VM's, and type: ssh remote_username@remote_host remote_host should be the hostname of the machine you want to connect to. You could even use simply the ip of the host you want to connect to. This guide is pretty basic if you want to get some more info ...

we're spamming network discovery with our VMs - What does that mean? Can you elaborate on that? we have to manually go in to each VM on creation, statically set the DNS to the TFS, join the test domain, reset to DHCP, and reboot the machine. - Why are you resetting them to DHCP? You should use static ip addresses on the test machines in order to: 1. Not ...

The following should do the trick, it will take all traffic on you public interface coming in for the VPN ports and change the destination to your VPN machine. iptables -t nat -A PREROUTING -i eth1 -p tcp -m multiport --dports 943, 1194 -j DNAT --to 192.168.122.4 iptables -t nat -A PREROUTING -i eth1 -p tcp -m multiport --dports 943, 1194 -j DNAT --to ...

Your static routes are invalid. You need to delete all your static routes from both sites and add the following routes on each router: Run on SITE2: /ip route add dst-address=192.168.3.0/24 gateway=172.30.2.222 Run on SITE3: /ip route add dst-address=192.168.2.0/24 gateway=172.30.2.221 Also the bridges are unnecessary so delete them too. You sould also ...

I'd suggest maybe you Google it before asking here. The first result is this, which seems to be exactly what you need to do.

For the benefit of those who will encounter this problem in the future I am posting the solution. After applying cross-testing I ruled out particular operating system, physical machine to end up on a broken port on the network switch.

It may be a problem with how TCP window interact with the NIC driver. First, check that TCP window scaling is enabled, issuing sysctl -a | grep net.ipv4.tcp_window_scaling. If it is not enabled, activate it using sysctl net.ipv4.tcp_window_scaling=1 and retry your test. If it does not work, you may be in need of manual tuning of TCP parameters. As it can ...

You might want to look into setting up your dns in a consistent manner using sub-domains. To start with you could have your website respond to www.example.com only and redirect example.com in IIS using http redirection. But you should really be using sub-domains specific for each action. vpn.example.com mail.example.com www.example.com

Use SHIELDED ethernet cables labeled STP or even SSTP (foil and braid). UTP are for typical office applications (cheapest, so you end up seeing these routed through walls by inexperienced installers). There is also FTP. On a factory floor or harsh noise environments you need Shielded. I am not sure how but these switches and cables can also be grounded ...

You can safely disable anything that you do not need. For example, does your server get its IP address and gateway settings from DHCP? If Yes -> You can not disable DHCP. If No -> You can disable DHCP. Do you need your server to response to pings? If no, feel free to disable ICMP rules. Do you use IPv4 and not IPv6 at all? Feel free to disable all IPv6 ...

PfSense is capable to do what you want - it doing load-balancing on a Multi-WAN connection. The only thing you may be need bonding on ISP side to get combine Up/Down traffic. If you ISP won't to do bonding, you can try 3rd party provider such as Mushroom Networks To protect traffic from abuse by employees, you can use on PfSense proxy with authentication. ...

Where are you located? Do you have access to a local consultant? I'd have someone come out and diagnose the problem based on the information you've provided. My recommendation would have been a link balancer. I use Elfiq, but I suppose the Peplink can also work. If it's configured incorrectly, you may be able to call Peplink for help. In terms of speed, ...

The main thing to check is that both VMs uses the virtio-net driver. If so, any other tuning you can do at the software switch level is going to be almost irrelevant. On the other side, a correct guest setup (eg: enabling jumbo frame) will be much more fruitful.

To fix this you need first the hostname for your server. You get that with: ~]# uname -n myhost.xyz Now you need the IP address for your machine, you get that with the ip command. Your output can differ depending on how many interfaces you have on your server. ~]# ip addr show 10: eth0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc ...

In case you mean "Virtual Private Server" with "vps" you may try to connect those two devices with a VPN-Tunnel. After the connection is established you may forward your desired ports to the VPS. In this way you can use your Sri Lanka IP address with your VPS Server. Hope this helps.

So your gateway IP is 192.168.1.120. What is its subnet mask? If it is 255.255.255.0, in no way you can use a 192.168.2.x IP and hope that it works. Client IP and network gateway must be on the same network, and this is the very same reason Windows is getting you an error. EDIT: maybe you can assign two IP addresses on you Windows machine, ...

I guess the gateway is something like 192.168.1.X since it worked while the server was in that range? Then you need another subnet mask, the smallest mask to be usable here that has both the server and its gateway in the same network ist 255.255.252.0. But the networks also needs to be configured in a way that allows that mask to be used. You should ...

3 options: You need access-points with support for 802.11q. This is an extension on regular WIFI that adds VLAN support to Wifi. Be warned: These things are very expensive. The other solution is to use access-points that can broadcast multiple WIFI LAN's and assign each of these WIFI LAN's to a different VLAN. This is easier to setup and less expensive ...

As per this link, it seems that mininet uses tc commands to set packet loss, delay etc. internally. It tries to overwrite the qdisc file, therefore, it errors RTNETLINK answers: Invalid argument. To set packet loss set it in mininet script itself by using loss parameter while creaqting a link. For an example see this.

Microsoft doesn't have this kind of information publicly announced: https://azure.microsoft.com/en-us/documentation/articles/azure-subscription-service-limits/ They only things remotely helpful to your case is to know that the limit for concurrent TCP connections for a virtual machine or role instance is 500K.

It's a hostname resolution issue, as you suppose, on the standalone server. The TNS alias on the standalone server, where the name dbserver is used, seems different from the one on the servers where the tnsping is working, where the IP 192.168.0.231 is used. You can modify the tnsnames.ora file on the standalone server to use the IP 192.168.0.231 or add an ...

Definitely, it's better to export/import the complete VM information, not only the disks. If you still have access to your original host, find your VM's definition (XML format). In Ubuntu it resides under /etc/libvirt/qemu, not sure about CentOS and likes. You can just copy it to the same location (with libvirt service stopped) or import using virsh. You may ...

It would depend on your switch. Professional switches offer LACP support (802.3ad link aggregation). With LACP you can bond multiple cables and/or NICs together. This way you have more speed (although it will not split up single flows - but in your case you have atleast 80 flows). If your switch does not support LACP, you can have different IP-adresses ...

I'd suggest using an appropriate tuned-adm profile for your I/O configuration. For this setup, it sounds like yum install tuned-utils and tuned-adm profile enterprise storage would be helpful. On the kernel side, you can set send/receive buffers: net.ipv4.tcp_window_scaling = 1 net.ipv4.tcp_rmem = 4096 87380 16777216 net.ipv4.tcp_wmem = 4096 65536 16777216 ...

Rather than trying to get two subnets to coexist in the same vlan, you get the computers to use a different vlan depending on which OS boots up. Two make this happen you need to do two things. The first step is to configure the ports on your network switch(es). Set the ports so the default (untagged/native) vlan is the existing vlan for your lab (Windows ...

You want to use Route.exe to specify the interfaces that should be used.

You can use the route command to make local traffic go through the bridged interfaces and non-local traffic through the modem.

You cannot add two differents gateway to the same network. From ubuntu1, you must define which interface will be the route to 192.168.4.X, you can go through either 192.168.1.102 or 192.168.2.102 or 192.168.3.102. Once you've set routing by 192.168.1.102, the only way to route by 192.168.2.102 is to remove 192.168.1.102 and add 192.168.1.102. Following ...

Not sure where you got those ACLs, wouldn't redirect scheme https code 301 if !{ ssl_fc } or redirect scheme https code 301 if {hdr(host) -i yourdomain.example.com } !{ ssl_fc } be a cleaner solution?

It is ignored. It's perfectly normal for a switch to handle only a subset of the VLANs used on some of its connected ports.

I ended up fixing this problem by switching to a different company. SecurityMetrics had no trouble with our network. (And I never did hear back from Trustwave with anything helpful.)

So you would like the machines to be either in one VLAN or in the other VLAN depending on if the one or the other system is booted (dual boot). This is possible if the network cards and the their drivers you use in Windows support VLAN / tagging. You would need to: Configure VLAN id and tagging on each of the computers and for each of the boot option, so ...

It can introduce performance problems since packets to the broadcast IP address are broadcast to all hosts on the segment. This additional traffic which is intended for only one host but send to every host can negatively impact the performance of those hosts needlessly receiving that traffic. Some switches can rate limit broadcast traffic. If your switch ...
