Hi List !
I want to use lsh 1.4.2 on a distribution which I build myself. I have a problem login in as non root. Connecting to sftp-server or lshd as root works fine.Apr 18 14:43:55 192 lshd[370]: lshd: do_exec_shell: fixing up name of shell...
I send you a part of the log:
Apr 18 14:43:55 192 lshd[370]: lshd: exec_shell: argv0 = '-sh'. Apr 18 14:43:55 192 lshd[370]: lshd: exec_shell: After -u Apr 18 14:43:55 192 lshd[370]: lshd: exec_shell: After -g Apr 18 14:43:55 192 lshd[370]: lshd: exec_shell: After -i Apr 18 14:43:55 192 lshd[370]: lshd: exec_shell: Argument list: Apr 18 14:43:55 192 lshd[370]: lshd: 'lsh-execuv' Apr 18 14:43:55 192 lshd[370]: lshd: '-u' Apr 18 14:43:55 192 lshd[370]: lshd: '502' Apr 18 14:43:55 192 lshd[370]: lshd: '-g' Apr 18 14:43:55 192 lshd[370]: lshd: '100' Apr 18 14:43:55 192 lshd[370]: lshd: '-n' Apr 18 14:43:55 192 lshd[370]: lshd: 'ftpuser' Apr 18 14:43:55 192 lshd[370]: lshd: '-i' Apr 18 14:43:55 192 lshd[370]: lshd: '--' Apr 18 14:43:55 192 lshd[370]: lshd: '/bin/sh' Apr 18 14:43:55 192 lshd[370]: lshd: '-sh' Apr 18 14:43:55 192 lshd[370]: lshd: exec_shell: before exec
i think the problem is here:

Apr 18 14:43:55 192 lshd[369]: lshd: write_buffer: do_write length = 56
Which file wants lshd to open there, maybe I have set the wrong permission to this special file.
Thanx for help, regards

Do you have $prefix/sbin/lsh-execuv executable for root? (Did you copy the binaries yourself or used make install?)

As Pontus already said, it's trying to exec lsh-execuv (a program used to make sure that secrets in the lshd address space can't leak in the middle of the fork, setuid, exec sequence).
So make sure you have lsh-execuv installed in the right place, usually $prefix/sbin/lsh-execuv.
I'll patch the error message to include the full filename, as given to exec().
