(Read more HERE.).Users can log in but I cannot get my remote software working because they don't know the administrator passwords to install it on them. So this veterinary clinic is asking me to fix their computer network but they don't know their network passwords. Best way to approach a poorly-maintained network Windows.I hope this helps everyone! Feel free to leave any comments if you wish for me to clarify. I also then changed the test vm's interface file so it would get a dhcp addr and once I rebooted, it was able to recieve dhcp addrs. Once I finished that, I was able to run apt-get update and ping my dns names. ![]() Lastly, I found that the test vm was not adding in the nameserver to its nf, so I added a file called tail to /etc/resolvconf// and simply added the dns server's ip for that subnet: nameserver 10.1.1.10 I had already done that prior to this question, but here is an article to do that configuration: The next thing to achieve the end-state is to configure your router to allow inter-vlan communication. I also removed the two post-up route lines, since they were not needed.įinally, I needed to fix nf here I added the lo interface and commented out the no-dhcp-interface: interface=lo Not sure if they are needed (hopefully someone else can clarify that) but this is what I had added: up route add default gw 10.2.1.1 The only change is to eth0, in which these three lines were already there. In /etc/network/interfaces, you specifie the ip addr you want for that nic, use a netmask of 255.255.255.0, and define the network for that nic. The first thing we did was fix the dnsmasq server. I talked to a friend of mine who has dealt with this type of thing before and here is what we did to get the environment to the end-state.įirst, I never had to use dnsmasq -y, this worked as soon as I restarted the dnsmasq service and the test VM So, to restate, I want to get what I have to the end state described above, and while I think the community would benefit more from having a step-by-step on how to set this type of environment up for their engineers, all I need is to figure what I need to do to move my current state to the end state. The dnsmasq server still works for the first subnet it was configured for (10.2.1.0/24) but I want to get it working for the other two subnets.Īlso, to clarify, when I say it doesn't work, I mean that the test vm I have on one of the new subnets can not ping it's subnet's dns addr and can not get to the internet. However when I try to ping 10.1.1.10 (the ip addr assigned to the dnsmasq nic for that subnet) it doesn't resolve. However, this is what I had:Īs of right now, if I statically give a vm on the 10.1.1.0/24 subnet an addr it can ping the other vms on the other subnets. ![]() I had option 6 set, but then I was told to run the command dnsmasq -y and I kept getting binding errors. ![]() I've set option three to specify each gateway as well as the range for each interface:ĭhcp-range=eth0,10.2.1.121,10.1.1.249,24h dhcp-option=eth0,3,10.2.1.1 I tried two types of listening in the dnsmasq config, one based on the static IP I assigned the nics and the other to the interface names, which is what I have currently: One question/answer that looked promising suggested that i put this in the config: post-up route add 10.2.2.10 via 10.2.2.1 dev eth1, post-up route add 10.1.1.10 via 10.1.1.1 dev eth2, but that didn't work either. I added in the gateway and nameserver options to the first interface, but that doesn't work. While I don't want there to be too many environment specific details (to keep it applicable to a wider audience), let me know if there is anything I need to clarify.ĭeclaring each nic's ip addr, netmask, network, and broadcast in the /etc/networks/interfaces file.
