"screen" - could not write to /opt/var/run/utmp bad file descriptor

Hi,

I followed the tutorial at http://wl500g.info/showthread.php?t=7643 in setting up screen in order that I may install enhanced c-torrent.

However I got stuck after installing "screen". What i did is as follows (using sudo bash):
1. ipkg install -force-overwrite ncurses
2. ipkg install -force-overwrite ncursesw
3. ipkg install -force-overwrite termcap
4. ipkg install -force-overwrite screen

The above steps completed without errors.

However when i execute "screen", i get the message:
could not write to /opt/var/run/utmp : bad file descriptor

So i went ahead to "touch /opt/var/run/utmp" to create utmp.

No good. I tried creating utmp as a directory in /opt/var/run/ as well but no difference.

What am i doing wrong?

Would appreciate any advice.

thanks.

Did some trial and errors and found the solution:

The missing file should be "/var/run/utmp" rather than "/opt/var/run/utmp" !!!

Solved it with "touch /var/run/utmp".

Hi!

touch /opt/var/run/utmp solve this problem but when I run 'screen' I get the message:

Cannot find termcap entry for 'xterm'.

What? And also not working nano editor:

Error opening terminal: xterm.

Hi,

termcap package already installed and updated...

nano already working my system but when I switch to oleg-optware feed (/opt/etc/ipkg.conf) and install uclibc-opt, libstdc++ and reinstall any already installed packages (and install wxbase and amule), screen and nano not working.
(xterm : unknown) I think uclibc-opt or libstdc++ lib files modified something my system or perhaps two termcap conf file in system... I :mad: mc is working and I can edit conf files (use xterm emulation)

sorry my english

Thanks, George

Do you have /opt/lib in your LD_LIBRARY_PATH?

to get nano and screen working again after switching to oleg-optware feedware run the command:

Code:

awk '/^Package:/{system("ipkg install -force-reinstall -force-defaults " $2)}' /opt/lib/ipkg/status

Solution for the "/opt/var/run/utmp" problem

The following worked for me:

sudo touch /opt/var/run/utmp
sudo chmod -R 777 /opt/var/run

Then "screen" did not display the error message any more.
