Assign a second IP address to the same VPS. Problem solved! Oh but wait, you can't do that on Digital Ocean. Lesson learned: Know your providers. Know your needs. Don't use providers that don't meet your needs, or work around their limitations.

Sounds like your netmask settings is incorrect. How large is your IP block 224 is 30 hosts if you have a few IP addresses it would be more like a 248 [cdir of 29] which is 6 hosts, 5 useful - this would account for the provider saying it is arpring the entire block. This would also account for a different path on the last few hops. Verify the subnet mask ...

I found that a slash notation mask of /32, implies one single host. Thanks Binary Hex Quad Dec 2ⁿ CIDR Number of addresses 00000000000000000000000000000000 00000000 0.0.0.0 2³² /0 4,294,967,296 4 G 10000000000000000000000000000000 80000000 128.0.0.0 2³¹ /1 ...

You can use a HTTP Basic authentication: <Location /> AuthType Basic AuthName "Secured" AuthUserFile /path/to/.htpasswd Require valid-user Satisfy any Deny from all Allow from 192.168.1 </Location> To generate the .htpasswd file: $ htpasswd -c /path/to/.htpasswd username-1 And to add additional users: $ htpasswd ...

Ping, like many other unix programs, use the C libraries on your unix system for name resolution. One of the functions used is inet_aton. The man page for inet_aton says: All numbers supplied as ``parts'' in a `.' notation may be decimal, octal, or hexadecimal, as specified in the C language (i.e., a leading 0x or 0X implies hexadecimal; otherwise, a ...

That behavior is actually due to a normal feature of ping and has no relation to your actual hardware. Indeed, prefixing the IP address (or part of it) with a leading zero will cause the number to be interpreted as octal. So 057 means 57 in base 8 which is 47. Thus ping will send the ICMP query to the machine located at address 10.10.208.47 and therefore ...

Another option may be to use LLMNR (Link-Local Multicast Name Resolution) — see also Multicast DNS — so the user could go the device based on an identifier such as its serial number or some such.

Yes, assuming you are talking a web interface. Similar to an appliance that reloads the page after a restart, you can put a http-equiv refresh in the pages header Eg. The following will instruct the browser to go to the provided URL after 20 seconds. Put this in the <head> or your HTML. <meta http-equiv="refresh" content="20;URL='your new ...

To start with, I was initially a bit confused because to me the way the router presents this configuration is a bit confusing. Primarily the "VLANX" terminology used in the listing down the left side. It finally clicked to me that these labels really has nothing to do with the actual 802.1Q VLANs and could be as easily been listed as "LANX", "NetworkX" or ...

Connect your Modem to the WAN port of your firewall. This will allow you to set LAN-WAN rules (for example drop all trafic where source != 192.168.1.z ). BTW. If your have connected all devices do LAN ports on your ZyWALL and it's working as a switch on those ports, then they will be able to connect regardless of your LAN-to-LAN rules. To allow to filter ...

You better start adding another subnet as you suggest two separate network and a router because the Broadcast domain with more the 200 users are considered unstable and poor performance. You cant manage a /16 on same broadcast network

Most defiantly a VPN server or VPN Server Software on your home device or software tool like LetMeIn.. Since you do not have access to your ISP's Modem to do any kind of port forwarding. It really limits what you can do. If its just the data you need to access then maybe a cloud service like dropbox, onedrive etc. Then you can share the data you need. ...

The fragment offset The fragment offset is a 13 bit field, and if you interpret those bits as an unsigned integer the maximum value will be 8191. But really it is counting multiples of 8 bytes, so it would make just as much sense to say the values go from 0 to 65528 in steps of 8. What exactly is the maximum valid value of this field itself is not ...

VPN is your best option, because you dont have control over your ISP router, the issue must be on your server side network when goes to wan, if both host are Linux you can use OpenVPN here a Wiki of Open VPN on Debian: https://wiki.debian.org/OpenVPN

This'll not work because this is just an IP alias (the interface does not really exist). Anyway, you would need a specific route for 1.1.1.60 on your router, but I am assuming this IS the same machine. I'd personally go for a virtual interface like this: ip tuntap add dev eth7 mode tap ifconfig eth7 1.1.1.60 netmask 255.255.255.255 ifconfig up And ...

I don't think it is possible with openvpn when you enable the client-to-client setting, but if you put a proxy in between and direct communication between openvpn clients on the same openvpn server to the proxy then communication between clients will appear to come from that proxy. I think in that case client-to-client does not (should not?) need to be ...

What's confusing you is that you are trying to convert the host part into a decimal value and sum it up to the network address while the host part is split in two octects. Your network is : 11000000.10101000.10110000.00000000 Your netmask is : 11111111.11111111.11111110.00000000 Your wildcard mask (the part that will change) : ...

I'll try to clarify what I interpret as your source of confusion: An IPv4 address is a single 32 bit integer but it's not normally formatted that way when we write out an address. As I'm sure you are aware, the norm is to write the address as [first eight bits in decimal].[next eight bits in decimal].[next eight bits in decimal].[last eight bits in ...

The simple reason is of course that a public IP-address is a internet network address and not a street address with a fixed geographical location. An simple IP-address to Location database is similar to using the logic of an old-school landline telephone number (which was somewhat geographically fixed with a country code, area code and local subscriber ...

Different geolocation sites pull their location data from different databases. There are a lot of these databases and IP addresses get reassigned frequently so it can be difficult to keep the current location of an IP address owner up-to-date in every database all the time.

10.0.0.0/8 is a private address range, and as such will never be reachable from the outside. In your nmap, new.tooplas.com resolves to 10.0.1.15, and in another you have 68.179.41.131. So i'm guessing your network topology is as follows: Your LAN uses 10.0.0.0/8 internally Your default gateway (10.0.0.1) has a public IP 68.179.41.129 You have a range of ...

Have you considered defering the decision to the end user at runtime, through a configuration parameter ? This is a standard practice for this problem. The reason is there is no systematic foolproof way to figure "the" local IP address (a host may be multihomed, may be running a v4/v6 dual stack, a VPN, etc..). Runtime configuration will make the sysadmin's ...

I very strongly suspect that the problem is this line in the qemu host's iptables -t nat -L -n -v: 76 6384 MASQUERADE all -- * * 10.10.15.0/24 !10.10.15.0/24 This is causing original (ie, not return-half) traffic from hadoop2 to driver to be NATted to 10.10.15.1. You could test this hypothesis by exempting just the traffic ...

You can set up port forwarding on the physical machine, so that some physical machine's port in physical network is forwarded to the VM SSH port. For example if the physical machine is 10.10.10.1 and VM network 192.168.0.0/24, then port forwards can be like this: 10.10.10.1 port 225 forwarded to 192.168.0.1 port 22 10.10.10.1 port 226 forwarded to ...

In the end I decided to go a different route (no pun intended). I actually have multiple physical NICs installed and was using them for other things. I since have learned something new about clustering. I have always in the past dedicated a NIC for the sole purpose of the cluster heartbeat. We my heartbeat always had a single point of failure. That ...
