Sir Tiger, Try to check the sshd_config if the following parameter is set:
AllowUsers root This will limit to only allow root access on the ssh service. config for sshd can be be found at /etc/ssh/sshd_config maybe, it caused the problem you encountered.

I can ssh to it as root, but I can't ssh as a regular user nor (once in as root) can I sudo, su or login as a regular user. I boot from a USB drive, so it's not a big deal, technically, to just make another boot drive. However the users will howl if I take it offline to fix it :-). Instead, I'm posting this as a puzzle that interested people can try to help solve without rebooting :-). 1. Originally I had a good USB boot drive built as per tonido instructions (first partition is /, optional swap second partition, make first partition active and untar modules.tar.gz and rootfs.tar.gz in the first partition). 2. I stopped the plugcomputer and brought that flash drive to another computer, attached a laptop harddrive in USB enclosure (I wanted to use the bigger drive as my new drive on the plugcomputer, there's only one USB port, unfortunately). 3. I did a tgz of the flash drive and extracted that onto the first partition of the laptop drive. When I booted with the new drive all was well. After installing a whole bunch of other packages though (I don't know what all those packages are anymore, but just installing them should not have broken jaunty this way) and miscellaneous fiddling, I found out that I couldn't ssh as a regular user anymore, or (from root) sudo as a regular user. strace doesn't help much. e.g., when I do: "#strace -ff sudo su -u tiger bash" at the end all I get is: execve("/bin/bash", ["bash"], [/* 16 vars */] <unfinished ...> +++ killed by SIGKILL +++ which I know, and which doesn't tell me why. I'll certainly just install things again over the weekend. But if I can avoid the downtime and perhaps provide some entertainment to the people on the list, all the better :-). tiger -- Gerald Timothy Quimpo http://bopolissimus.blogspot.com [email protected] [email protected] Even Tom Lane said: "Or, if you're worried about actions from functions, use a trigger to do the logging. There are approximately no cases where a rule is really better than a trigger :-( " _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List http://lists.linux.org.ph/mailman/listinfo/plug Searchable Archives: http://archives.free.net.ph
