re-adding dev () nmap org Hey, so, this is weird indeed, but you didn't give us enough information to really troubleshoot this. What OS are you running, and what version? What's the make and model of the WiFi card you're using? Is it USB or integrated (like on a laptop)? And, just to confirm, are you using the same computer both at home and in the library? BTW the library cannot "see" nmap before it starts (at least on your computer) so what could be happening is that your OS does not recognize your wifi card when you're in the library. But as to why, I don't know. BTW, I tried looking for the other two messages you sent in the list archives (https://seclists.org/nmap-dev/) to see if you already gave the info, but I can't find them. If you already sent the info above just point me at those please :) On Sat, Mar 16, 2019 at 7:36 PM Mike . <dmciscobgp () hotmail com> wrote:
ty for responding. so it gets even weirder. this is all happening at a public library that offers free wifi. i know what ethernt is, i used it for 10 years. so someone explain this if you can because i am BAFFLED! i have no connection at my home for the time being so i come here to the library. i am using a WIRELESS CARD/CONNECTION. at home i have NO CONNECTION because the wifi in the apt complex is locked down BUT i can still OPEN NMAP! and it uses "eth0" when i do!? but at the library it will not open eth0????? that is all it ever sees. that and the loopbacks. turning NPCAP on or off doesnt help mattes. now i know this library locks down their router quite well but how in the world could they see nmap before it is even fired up????? thought i knew networking but this has be stumped! the packet traffic at the lib shows me calling and finding a DHCP and then getting the proper config and going foward with a connection like any DHCP would. but nmap does not work?????????????? ty ------------------------------ *From:* Claudio M <flyingstar16 () gmail com> *Sent:* Saturday, March 16, 2019 11:46 AM *To:* Mike . *Cc:* nmap-group *Subject:* Re: please respond to this? eth0 is, normally, the identifier of an ethernet card (the one with the cable); wireless interfaces start with "w". To see all the interfaces available on your system use either "ifconfig" or "ip link show", then use that in nmap. FYI newer Linux versions are using a different way of identifying cards, so your card could be called something like wlp2s0. Read https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/ for more info.
