Top Forums Shell Programming and Scripting SSH w/ command in authorized_keys apparently needs pty Post 302537730 by KenJackson on Saturday 9th of July 2011 03:48:05 PM

No matter what I echo, it never writes to the log.
In fact, I tried to just touch the log, but it was not created.
The "command=" options seems to always be ignored.

Actually, that's not right. I put -v on ssh in my experimenting and found that ssh not only looks at the key I provided on the command line with -i, but it also considers the other key that is held in memory in unencrypted form by an ssh-agent process. It apparently chooses the one it wants, NOT the one I specified.

Race condition with PTY

I've been experimenting with pseudo-terminals and found something I don't quite understand. Writing an EOF character to the master end doesn't work quite as I expect. Once I've written any other data, the master pty seems to treat a single ^D as a seperator, i.e. writing "abcabc" would let cat do... (1 Reply)

SSH-LDAP-HELPER(8)					    BSD System Manager's Manual 					SSH-LDAP-HELPER(8)

NAME
ssh-ldap-helper -- sshd helper program for ldap support SYNOPSIS
ssh-ldap-helper [-devw] [-f file] [-s user] DESCRIPTION
ssh-ldap-helper is used by sshd(1) to access keys provided by an LDAP. ssh-ldap-helper is disabled by default and can only be enabled in the sshd configuration file /etc/ssh/sshd_config by setting AuthorizedKeysCommand to ``/usr/libexec/openssh/ssh-ldap-wrapper''. ssh-ldap-helper is not intended to be invoked by the user, but from sshd(8) via ssh-ldap-wrapper. The options are as follows: -d Set the debug mode; ssh-ldap-helper prints all logs to stderr instead of syslog. -e Implies -w; ssh-ldap-helper halts if it encounters an unknown item in the ldap.conf file. -f ssh-ldap-helper uses this file as the ldap configuration file instead of /etc/ssh/ldap.conf (default). -s ssh-ldap-helper prints out the user's keys to stdout and exits. -v Implies -d; increases verbosity. -w ssh-ldap-helper writes warnings about unknown items in the ldap.conf configuration file. SEE ALSO
sshd(8), sshd_config(5), ssh-ldap.conf(5), HISTORY
ssh-ldap-helper first appeared in OpenSSH 5.5 + PKA-LDAP . AUTHORS
