Thanks for all the responses, I got it working. I downloading a v2.4.6 off a thirdparty website, FTPed it to my linux box, downloaded a tftp client, turned on tftp on the 678 and set my IP as the remote address. Then I just put the file from tftp and all was grand. One kicker was that I had to the set "mode" on the tftp to binary before the cisco would accept the file. That took me about 5 failed transfer attempts before I checked the "show error" on the 678 which told me what to do. Thanks guys!
