Hello,
I've been using the (great :) mconsole exec feature without problem for
some time. Using simple commands like the following ones, all goes right
(they behave as excepted, doing their work inside the virtual machine):
(/root/.vnuml/s) exec touch /tmp/bar
OK The command has been started successfully.
(/root/.vnuml/s) exec cp /tmp/bar /tmp/foo
OK The command has been started successfully.
However, I'm finding problems trying to execute init.d scripts (i.e.,
the usual system service star/stop/restart management scripts that come
under /etc/init.d/ in almost every GNU/Linux distribution).
In particular, I've tested with the /etc/init.d/apache2 script (that
comes with apache2 web server software) but it doesn't work (i.e., the
apache2 server doesn't start):
(/root/.vnuml/s) exec /etc/init.d/apache2 start
OK The command has been started successfully.
I've tried some debugging myself: editing the first line in
/etc/init.d/apache2 (from "#!/bin/sh -e" to "#!/bin/sh -xe") in order to
"verbosize" the script, then executing:
(/root/.vnuml/s) exec /etc/init.d/apache2 start > /tmp/apache2.txt
OK The command has been started successfully.
Then examining /tmp/apache2.txt in the virtual machine:
A2:~# cat /tmp/apache2.txt
Starting web server: apache2 ++ /usr/bin/tput setaf 1
failed!++ /usr/bin/tput op
A2:~#
If I run "/etc/init.d/apache2 start" in the virtual machine xterm or in
a SSH session to it, it works (i.e., the apache2 starts). This fact
discards a problem in the /etc/init.d/apache2 script itself. In this
case, this is the output of the script:
+ ENV='env -i LANG=C PATH=/usr/local/bin:/usr/bin:/bin'
+ NO_START=0
+ set -e
+ '[' -x /usr/sbin/apache2 ']'
+ HAVE_APACHE2=1
+ . /lib/lsb/init-functions
++ FANCYTTY=
++ '[' -e /etc/lsb-base-logging.sh ']'
++ true
+ test -f /etc/default/rcS
+ . /etc/default/rcS
++ TMPTIME=0
++ SULOGIN=no
++ DELAYLOGIN=no
++ UTC=yes
++ VERBOSE=no
++ FSCKFIX=no
++ RAMRUN=no
++ RAMLOCK=no
+ test -f /etc/default/apache2
+ . /etc/default/apache2
++ NO_START=0
+ '[' 0 '!=' 0 -a '' '!=' stop ']'
+ APACHE2='env -i LANG=C PATH=/usr/local/bin:/usr/bin:/bin
/usr/sbin/apache2'
+ APACHE2CTL='env -i LANG=C PATH=/usr/local/bin:/usr/bin:/bin
/usr/sbin/apache2c
tl'
+ case $1 in
+ log_success_msg 'Usage: /etc/init.d/apache2
{start|stop|restart|reload|force-r
eload}'
+ echo 'Usage: /etc/init.d/apache2 {start|stop|restart|reload|force-reload}'
Usage: /etc/init.d/apache2 {start|stop|restart|reload|force-reload}
+ exit 1
I don't know which is the cause of the problem and how to solve it, so I
come to the list in the case somebody could provide some idea or related
experience, please. I've looked in the tput man page, but it doesn't
help me too much (I'm not an expert on terminals, shells, etc.).
Any help on the issue is really welcome, because I'm starting to get a
bit crazy figuring out what the problem can be :)
I've experienced the problem for /etc/init.d/apache2, but I guess that
other init.d scripts may suffer it, because all they are quite similar.
Some reference stuff (please, ask if you need some other information):
- apache2 version: 2.2.3-5 installed through APT in Debian virtual machine
- guest kernel: 2.6.15.7 with bs3 and tls patches
- host kernel: 2.6.21-2-686
Thanks! :)
Best regards,
