This is more of an "here's how I did it, it may save you some time, maybe you can use it directly, maybe you can learn from it and adapt it" kind of deal, it's not next-level magic.Īs with all collectd-exec scripts: you need collectd-mod-exec installed and have it run the script. Really, I'm not doing any rocket surgery here, it's just parsing a string into variables that can be shoved into the rrd/collectd database. The script can probably parse the output right away. Line so it receives the output of xdslctl info -stats and puts it into the $xdslinfo variable. Modify the xdslinfo=$( ( sleep 2 echo "$MODEM_LOGIN" sleep 1 echo "$MODEM_PASSWORD" sleep 1 echo "xdslctl info -stats" sleep 2 echo "quit") | nc $MODEM_ADDR 23 2>&1 )

Zhone dropbear ssh defauly manual#
Matt Johnston ( Pape ( wrote this manual page.My Techicolor modem has SSH running and I can execute xdslinfo commands via SSH SSH_AUTH_SOCK Set to a forwarded ssh-agent connection. If a shell was requested this is set to an empty SSH_ORIGINAL_COMMAND If a 'command=' authorized_keys option was used, the original command is specified in this variable. SSH_TTY This is set to the allocated TTY if a PTY was used. The variables below are set for sessions as appropriate. This can also be disabled per-user by creating a fileĭropbear sets the standard variables USER, LOGNAME, HOME, SHELL, PATH, and TERM. These are of the form generated by dropbearkey.īy default the file /etc/motd will be printed for any login shell (unless disabled at compile-time). PasswordAuth: boolean : no : 1 : Set to 0 to disable authenticating with passwords. BannerFile: string : no (none) Name of a file to be printed before the user has authenticated successfully. verbose: boolean : no : 0 : Set to 1 to enable verbose output by the start script. Specified on the commandline with -d or -r. Default Description enable: boolean : no : 1 : Set to 0 to disable starting dropbear at system boot. Host key files are read at startup from a standard location, by default /etc/dropbear/dropbear_dss_host_key and /etc/dropbear/dropbear_rsa_host_key or The authorized_keys file and its containing ~/.ssh directory must only be writable by the user, otherwise Dropbear will not allow a login using public key Note that a user can still obtain most of the same functionality with other means even if no-pty is set.Ĭommand=" forced_command" Disregard the command provided by the user and always run forced_command. No-X11-forwarding Don't allow X11 forwarding for this connection No-agent-forwarding Don't allow agent forwarding for this connection No-port-forwarding Don't allow port forwarding for this Restrictions are comma separated, with double quotes around spaces in arguments. Subset (keys with unknown restrictions are ignored). This is the same format as used by OpenSSH, though the restrictions are a Īnd can be extracted from a Dropbear private host key with "dropbearkey -y". ~/.ssh/authorized_keys can be set up to allow remote login with a RSA or DSS key. I idle_timeout Disconnect the session if no traffic is transmitted or received for idle_timeout seconds.

The trade-off is that a session may be closed if there is a temporary lapse of network connectivity. This is useful for working around firewalls or routers that drop connections after aĬertain period of inactivity. K timeout_seconds Ensure that traffic is transmitted at a certain interval in seconds. Increasing this may improve network performance at the expense of memory use. W windowsize Specify the per-channel receive window buffer size. a Allow remote hosts to connect to forwarded ports. If not specified, the default is /var/run/dropbear.pid P pidfile Specify a pidfile to create when running as a daemon. Use this option to run dropbear under TCP/IP servers like inetd, tcpsvd, or tcpserver. up to 10 can be specified (default 22 if none If just a port is given listen on all addresses. p port Listen on specified address and TCP port. m Don't display the message of the day on login. E Log to standard error rather than syslog. Use the contents of the file rsakey for the rsa host key (default: /etc/dropbear/dropbear_rsa_host_key). This file is generated with dropbearkey(8). Implementations use the term "DSA" rather than "DSS", they mean the same thing. Use the contents of the file dsskey for the DSS host key (default: /etc/dropbear/dropbear_dss_host_key). Display the contents of the file banner before user login (default: none).
