I have a device that the vender is telling me the only way to change it's network settings is by telnetting into it. They have a program that can connect via serial to 'view' it's settings, but that it, just view. Subnet mask has somehow been set to 255.255.255.255. IP is 10.103.1.40, gateway is 10.103.1.8. Is there anyway to get into this via telnet? Specific ip/subnet/gateway settings I'd need to set on the pc connecting to it? I've tried setting an ip of 10.103.1.41 and a range of different subnet masks, but nothing let me even ping the device. The only thing that gives me hope is that after pinging it, its MAC address shows in my arp table. Any help would be greatly appreciated. -- Posted 'as is'.

Which Vendor & Model device ? - Broadband Reports forums are usually a good resource for configuring devices. Usually somebody there has prior experience with most hardware. http://www.broadbandreports.com/forums
I highly doubt anyone will have experience with this particular device, that's why I asked the question as a generic network question and not device specific. It's a RS232 LAN Converter from Westerstrand Time Distribution out of Sweden. My vender first had this issue with the first lan converted they sent. They replaced that one and after I received the new one, I set my settings, saved them, then couldn't access the device anymore (just like what happened with my vender on the first device). After about 2 weeks of very very slow email conversation, they finally gave me a propgram that could read the settings through a serial connection. That's when I noticed the invalid subnet mask. And the thing is... I never touched the subnet mask when I was setting it up for our network as it was already correct (255.255.255.0). I'll try the forum you suggested, but still would like help here as well if anyone out there can help. -- Posted 'as is'.

Thanks for the follow-up. I checked the website and only found a minimal amount of documentation on the device - just a simple PDF product spec and environmental doc. Maybe someone at BB-Rpts can help.
I know that the subnet mask should be 255.255.255.0, I'm not sure what happened to set it to the invalid entry. I've tried a cross-over cable, nothing is working. Thanks... -- Posted 'as is'.

I'm assuming this is a routing or switching device. Have you considered simply replacing it with a device you know you can access?
Yes, but my vender has already replaced one that they screwed up (or rather that the device screwed up on them by doing the same thing it did to me). Now the manufacturer is hesitant on just sending a third device. It's an RS232 to LAN converter from Westerstrand out of Sweden. -- Posted 'as is'.

With this subnet mask, there are no available host IPs on the subnet. Neither the assigned IP or the assigned gateway have any meaning here, as this piece of equipment will not be talking to anything. Does this device have a reset switch or a CMOS-clear jumper (or battery) to pull out? Or is there as serial console connection that you can use to talk to the device with?
There's no reset switch, no jumpers, no battery. There is a serial connection (as it's an rs232 to rg45 lan converter), but with it's current firmware rev, the companies new program that allows settings the network settings through the serial connection will not work. My vender is flashing a new chip and is sending it to me to arrive tomorrow. With that, I should be all set (I hope). -- Posted 'as is'.
