![]() ![]() Any thoughts on how to fix this error? Attachment(s): I also attached my code and makefile (with. However, if I create a simple blink script inside the Arduino IDE and upload it using the IDE, it works flawlessly. ![]() I also tried programming an ATtiny13a chip, giving the same error. I tried quitting the Arduino IDE, Restarting my mac, 0.1uF and 1000uF cap, unplugging the programmer's usb cable and a different usb port. I installed Avrdude with Homebrew and also installed CrossPack. Now, since I think it uses Xcode, I moved it back to the applications folder on my mac. Maybe it has something to do with the fact that I moved Xcode to my external hdd, because I ran out of space. The expected result was a write to the chip, followed by a flashing LED (blink test code). It worked before, so I'm a little surprised. I'm using an Arduino Mega as programmer, with Arduino as ISP sketch flashed on it, 10uF cap across reset/gnd and isp wires and vcc/gnd connected to the chip that I want to program. Ioctl("TIOCMGET"): Inappropriate ioctl for device This would allow you to use sudo commands in your script without having to hardcode a password.I wanted to program an ATmega32A PU, but upon flashing (using make flash or make install in terminal), I get this error:Īvrdude: ser_open(): can't open device "/dev/tty.usbserial-1420": Resource busy Your script, would simply need to do something like: read -p "Please enter your sudo password: " -s sudopasswdĮcho "$sudopasswd" | sudo -S x11vnc -storepasswd ~/.vnc/passwd Read -p "Please enter your sudo password: " -s sudopasswdĮcho "$sudopasswd" | sudo -S tail -1 /etc/shadowĮcho "$sudopasswd" | sudo -S ls -la /root/ Here is an example script to demonstrate the process: #!/bin/bash Tail: cannot open `/etc/shadow' for reading: Permission ~]$ echo | sudo -S tail -1 /etc/shadow Sudo has an option -S that allows it to read the passwd from STDIN. ![]() Sudo script -q /dev/null x11vnc -storepasswd ~/.vnc/passwd <<ENDDOC Sudo script -q -c 'x11vnc -storepasswd ~/.vnc/passwd' /dev/null Printf '%s\n' 'password' 'password' 'y' | Sudo script -q -c 'x11vnc -storepasswd ~/.vnc/passwd' <<ENDDOC /dev/null Solutions using the script command: # GNU script command # Write password to ~/.vnc/passwd? /n Password written to: ~/.vnc/passwd # Enter VNC password: stty: stdin isn't a terminal Sudo x11vnc -storepasswd ~/.vnc/passwd << ENDDOC The warning messages on Mac OS X 10.6.8 for not providing a pseudo-terminal for x11vnc: # x11vnc 0.9.14 This can be done with the script command or tools such as pdip ("Programmed Dialogue with Interactive Programs"). Will using expect be a better solution? If so, how would I use it in this case? (I have never used expect before but I have looked at a lot of examples since posting this question and I cannot get expect to work on my own.)Īnother option to avoid those warning messages is to execute x11vnc in a pseudo-terminal created by a UNIX command (see Using pseudo-terminals (pty) to control interactive programs). Write password to /home/user/.vnc/passwd? /n n In case it helps, the prompts look like this: I would appreciate a working example of how to implement sudo x11vnc -storepasswd ~/.vnc/passwd in a script. That obviously (from the error) does not work. My problem is related to x11vnc -storepasswd and here's my code: sudo x11vnc -storepasswd ~/.vnc/passwd << ENDDOC Please notice that this error message is from x11vnc -storepassword (not from sudo.) Stty: standard input: Inappropriate ioctl for device However, in one case I get this error: Enter VNC password: stty: standard input: Inappropriate ioctl for device In most instances the here-document approach handles this fine. I enter the password once and the script passes it to the various commands. I'm using here-documents in a bash script to automate installation and setup where a password is required many times. ![]()
