It could be any number of things, APC for example need a vendor option set in DHCP or a ³Magic² ping. It could be that the app just talks to it on L2 like Microtik¹s. I suspect the windows app will be your only option. -- Geraint Jones On 26/11/13 12:42 pm, "David Birdsong" <david () imgix com> wrote:

I compromised and ran out to the local Fry's to buy whatever switch I could find so as to allow some configuration to happen while we wait for the real network gear to show up. I left before confirming I could access the switch remotely; it was very late and I was pretty groggy and hey, any network gear has to be telnet'table this day and age. Of course I was mostly wrong. The switch expects some signed payload before allowing a telnet through. I found this: https://code.google.com/p/netgear-telnetenable/...but I'm having a hell of a time getting anything to respond. The most confounding part is the switch doesn't respond to a single SYN packet on low ports. I'm scanning all the ports now, but if nothing shows up, I'm not sure what a payload is good for if the switch doesn't ACK a single SYN. I'm curious if anybody's got any tips besides not using Netgear in the datacenter. I have the MAC, I've IP'd it via DHCP, and the model number: JGS524E and I can power cycle the switch as much as needed. P.S. long time listener, first time caller. i'm more of a sysadmin dangerously standing in for a proper network person. ------------------------------ Seems to me that you need to use their "Switch Configuration Utility" to manage the switch. I didn't read all the documentation, but that is what jumps out at me after a brief look. Maybe it will allow you to enable telnet or ssh from there. See the following link:No windows box handy, nor the desire for that hoop. ...but what magic is a windows app going to perform to wake up an unresponsive TCP stack?http://downloadcenter.netgear.com/en/product/JGS524E Jason
