Hallo, i have the a problem with ssh: i try to shutdown 30 or more systems, i generate a shell script (death.sh) to do this. It looks like this: ssh -T -l root -i /home/regman/.ssh/id_dsa.linuxprt -o StrictHostKeyChecking=no -oProtocol=2 -q -n -oBatchMode=yes lnx001'halt;' & ssh -T -l root -i /home/regman/.ssh/id_dsa.linuxprt -o StrictHostKeyChecking=no -oProtocol=2 -q -n -oBatchMode=yes lnx002'halt;' & ssh -T -l root -i /home/regman/.ssh/id_dsa.linuxprt -o StrictHostKeyChecking=no -oProtocol=2 -q -n -oBatchMode=yes lnx003'halt;' & ssh -T -l root -i /home/regman/.ssh/id_dsa.linuxprt -o StrictHostKeyChecking=no -oProtocol=2 -q -n -oBatchMode=yes lnx004'halt;' & ssh -T -l root -i /home/regman/.ssh/id_dsa.linuxprt -o StrictHostKeyChecking=no -oProtocol=2 -q -n -oBatchMode=yes lnx005'halt;' & ssh -T -l root -i /home/regman/.ssh/id_dsa.linuxprt -o StrictHostKeyChecking=no -oProtocol=2 -q -n -oBatchMode=yes lnx006'halt;' & ssh -T -l root -i /home/regman/.ssh/id_dsa.linuxprt -o StrictHostKeyChecking=no -oProtocol=2 -q -n -oBatchMode=yes lnx007'halt;' & If i start it direct i a term, all is fine and all systems are down. But i have to schedule the task by a php-script. This php-script start with exec("death.sh) the shell-script, the php-script is start by cron ( i have to use php, because of the framework i use, i have no choice ;-( The a got this errors: tput: unknown terminal "unknown" tput: unknown terminal "unknown" tput: unknown terminal "unknown" tput: unknown terminal "unknown" tput: unknown terminal "unknown" tput: unknown terminal "unknown" tput: unknown terminal "unknown" tput: unknown terminal "unknown" tput: unknown terminal "unknown" tput: unknown terminal "unknown" tput: unknown terminal "unknown" tput: unknown terminal "unknown" tput: unknown terminal "unknown" tput: unknown terminal "unknown" tput: unknown terminal "unknown" and all systems are alive, no "halt" reach a system ;-( If i dont use the "-T" flag i got this error too: "Pseudo-terminal will not be allocated because stdin is not a terminal" i try the "-t" flag to, same error, and all alive.
