G+_T Nohands Posted July 17, 2015 Share Posted July 17, 2015 Does anyone remember how to do a network ping sweep from the cmd prompt in windows I'm missing a wifi attached printer and yes the stupid thing is plugged in and wifi is turned on and shows it see's a wireless signal (20 acre Farn no other wifi in range) even gave it a static IP 192.168.1.85 on subnet 255.2555.255.0 vlan 1 inside the printer router use to see it and now it has disappeared even checked the printer has wifi password and looks connected I'd love to know what some well meaning person did while I was gone a couple of days. Cannon MG7100 series wireless printer and cisco router where the web interface can't ping the printer on ip .85 nor see's other active ip unaccounted for on status Table. Fr. Robert Ballecer, SJ am I wasting my time trying to remember the command for a sweep or is cmd lines the best way to find it AND find out what happened to cause this. I'm worried to try mapping software I've not used before and unless there are free or budget friendly snmp based mapping software I doubt it would be easy to find out why and how it disappeared from my network and I remember port scan yet now it's not a download and I don't like outside system scanning my network as a good solution besides it's most likely not a port issue, is there a Padre approved software or method? Honestly if I knew who and could use my hands there would be some head slapping I've worked so hard my network is my baby I hate others messing with it. It's really sad I can't call a service due to my location and the last time my isp sent a guy out he looked at my switches and said it's beyond him and had to pay a service call to hear that. So Bryan Burnett and Fr. Robert Ballecer, SJ I need me some edumacation for the country networking troubleshooting. Link to comment Share on other sites More sharing options...
G+_Jeff Gros Posted July 17, 2015 Share Posted July 17, 2015 Maybe you're thinking of nmap? I don't think its installed by default though, so you'll have to download it. "nmap -sP" should do a ping scan. Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted July 17, 2015 Share Posted July 17, 2015 possibly: (add an extra % if used in a batch file) adjust subnet as needed FOR /l %i in (1,1,254) DO ping -n 1 192.168.1.%i Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted July 17, 2015 Share Posted July 17, 2015 also can you just look at the DHCP clients in the router? another plus for DHCP reservations. nmap (like Jeff Gros suggested) is free and an awesome tool. Link to comment Share on other sites More sharing options...
G+_Joshua Delaughter Posted July 17, 2015 Share Posted July 17, 2015 Angry IP scanner is also great for this job. Link to comment Share on other sites More sharing options...
G+_Fr. Robert Ballecer, SJ Posted July 17, 2015 Share Posted July 17, 2015 Also... you could ping the broadcast address, getting all the properly configured devices to respond, then check your arp table... For example, if your network is 192.168.1.x ping 192.168.1.255 ** Let the ping timeout ** arp -a Peace, Padre Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted July 17, 2015 Share Posted July 17, 2015 Fr. Robert Ballecer, SJ I kinda like that. but came up way short on active IPs. Link to comment Share on other sites More sharing options...
G+_T Nohands Posted July 20, 2015 Author Share Posted July 20, 2015 Fr. Robert Ballecer, SJ Even trying that it doesn't show up Padre and my wifi is basic vlan 1 and all devices that don't move or leave have a static ip mac binding. As you pointed out in last weeks Know How for normal home networks how you setup from your router should be simple but in my case I use and need managed switches so I can turn off sections because the router gets slammed with ip address assignments and DHCP requests it thinks it's under attack so I have to turn chunks off reboot the router then turn main source ports/uplinks back on 1 at a time. So the physical and virtual separation limits where it could be hiding but still the original description still is the problem I have a phantom printer that's temporarily a paper weight that has a copier. Guess I'll wait for the next time a friend can come out reset the printer to factory conditions wipe the software off corresponding devices and setup the printer all over again a bit of work but sometimes it's time to stop trouble shooting and just reset things from the point that u originally got it in unless that was broken lol Thanks for reminding me about the cmd line arp catch much easier AND to the point in looking for devices within a section however do you remember the cmd line command that list and pings every devices on the entire network and radiating config and spannig trees whe I set up the cmd promp direct through serial communication with main network router? Or do I need something like Putty to do full ip slash mac addresses that touch the network at that time? Link to comment Share on other sites More sharing options...
G+_T Nohands Posted July 20, 2015 Author Share Posted July 20, 2015 Eddie Foy That seems like interesting software but I'm using Enterprise networking equipment and designing with a think tank Group we like taking things too far beyond compatibility like I mentioned in other post as a quad my network is my baby because it allows me to interact withe my environment so I dislike outside software on my network or computers hooked up as admin level to the network just because it's opensource doesn't mean safe some have java and flash and the way I'm putting cameras and mics in all the rooms for an experimental network protocol outside software is unpredictable with what the group aptly named the Misfits are helping me with wireshark and Kali are the only programs I'm using for testing and upgrading to a Cisco 2921 and all routers and switches are managed Padre put me onto a lot of configuring it wouldn't do anything telnet putty and cmd line could do and the switches or routers couldn't do it's time to just take off and reset then reinsert the printer into the network but it is an interesting software I plan on looking at it maybe see if it can work in my network after research and review Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted July 20, 2015 Share Posted July 20, 2015 The only 'outside' software I mentioned was nmap. (and Kali is a long way from a 'program' and nmap is in Kali Lots of 'bad' stuff in Kali) The Commandline command is all built-in DOS/Windows. I'm all enterprise hardware here too; level 3 switches, Cisco 2851router ( Asus router only used as an AP for a vlan for 3 devices ) Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted July 20, 2015 Share Posted July 20, 2015 But in IOS just do a ping 192.168.1.255 Link to comment Share on other sites More sharing options...
G+_T Nohands Posted July 23, 2015 Author Share Posted July 23, 2015 Eddie Foy I know kali is not software in normal reference the group I do projects with use Kali and wireshark for integrity of the network reverse engineer problems and play with new ideas.
