OK, first we'll need to check you have root access to the sumvision(s) do you know how to use the vi editor ?and don't blame me if you brick one of them
Busybox has a <a href="http://http://www.busybox.net/downloads/BusyBox.html">built in command[/url] for getting / setting the hostname.You could try (when on command prompt)Code: [Select]hostnameThis should return Venus so now do:Code: [Select]hostname Venus2To set the hostname to Venus2 (or anything else)

If the power was completely removed e.g power cut (something we suffer from frequently) when it came back on it had reverted to Venus.Today I discovered this was due to the fact that Venus hostname was part of the flash and the only way to change it was to modify the firmware.I then found out that the spare Traxdata with the faulty USB has sightly different Firmware unique to Traxdata and is hostname is Traxdata_MMS, so i have just loaded the Traxdata firmware onto the Sumvision machine and my problem has no been cured.Thanks to all of you that have offered help over the last few days.One last request does anybody know how to Modify the firmware image to change the hostname in flash as it could be very useful because the Traxdata firmware has quite a few improved facilities even though it is the same version number as the sumvision.Once again thanks to you all for reading and suggestingRegardsAndy
Dunno .. have you got a link to the firmware ?
just gimme a link to one of em to look at
OK, there's no "easy" way to unpack and modify that img file as it's of an unknown file system.You could have a read of this:http://www.devttys0.com/2011/05/reverse-engineering-firmware-linksys-wag120n/I had a quick look at it with binwalker and there's a ton of output .. some of which would probably allow you to identify the filessystem, then you'd probably be able to extract it, mount the file system, modify it, and repack it .. but I haven't really got the time to figure it all out, sorry.For what you want to do it would probably easier to just modify it "in place"--
