Thanks to everyone who made suggestions on what might be wrong with my LFS 6.3 system.
I'm now able to connect to the new LFS box over either telnet or ssh. The solution involved paring away some complexity, which I'd probably misconfigured (e.g., reverting to an unwrapped sshd), and then realizing the client machine I was using for testing was my old LFS6 system, which I know has some bad problems (that's why I'm building a new one). I'd restored the old LFS6 system to a state where it is able to operate, but clearly some of the client programs I was using for testing (e.g., ssh) were munged up. Switching to a known working client "solved" the last problem. The one remaining connectivity glitch is something that's been posted about occasionally: when connecting to the new LFS6.3 system via telnet from certain clients, it takes 20 - 30 seconds to connect. The log (auth, I think) also always contains messages about ttloop: retrying XX times (where XX is some large number, sometimes as high as 90+). The "certain clients" are all Windows desktops (two are Vista, one is XP SP2). If I try to connect from the old LFS6 box via telnet it syncs right up. If anyone has some suggestions on what might be causing the problem I'm all ears. - Mark -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
