En un script se puede reproducir el siguiente problema con ulimit:

ulimit: 181: Illegal option -u

Esto ocurre cuando se utiliza una shell distinta de bash. Para evitarlo, y si no hay más consecuencias en el script, vale con cambiar de shell:

#!/bin/sh
#!/bin/bash

En la instalación de las VirtualBox tools en una imagen de VirtualBox, Debian 5.0 por ejemplo, puede ocurrir el siguiente error:

debian-xplico-demo:/media/cdrom# ./VBoxLinuxAdditions-amd64.run
-su: ./VBoxLinuxAdditions-amd64.run: /bin/sh: bad interpreter: Permission denied

Se soluciona con:

debian-xplico-demo:/media/cdrom# sudo sh /media/cdrom/VBoxLinuxAdditions.run"

El siguiente error compilando “ghostpdl“:

#kubuntu@kubuntu:~/xbuild/ghostpdl-8.70$ make
./obj/echogs -a ./obj/ldall.tr -s - ./obj/gsromfs1.o ./obj/plmain.o ./obj/plimpl.o  -lm -lpthread -ldl
sh <./obj/ldall.tr
/usr/bin/ld: cannot find -lXext
collect2: ld returned 1 exit status
make[2]: *** [obj/pcl6] Error 1
make[2]: Leaving directory `/home/kubuntu/xbuild/ghostpdl-8.70/main'
make[1]: *** [pdl-product] Error 2
make[1]: Leaving directory `/home/kubuntu/xbuild/ghostpdl-8.70/main'
make: *** [pcl] Error 2

se soluciona instalando la siguiente librería.

kubuntu@kubuntu:~$ sudo apt-get install libxext-dev

En algunos entornos también puede ser necesario libx11-dev:

kubuntu@kubuntu:~$ sudo apt-get install libx11-dev

Si se desean realizar por ejemplo comparativas de distintos binarios para comprobar su rendimiento, una de los parámetros a estudiar puede ser el tiempo de ejecución de los mismos sobre la misma máquina.

Para ello, en vez de utilizar un script bash con el comando “date –rfc-3339=ns”, se puede utilizar el comando “time” seguido del programa, a modo de cronómetro.

carlos@WhenIGrowUp:~/tmp/capturas.tests$ time cat /etc/debian_version
lenny/sid
real 0m0.003s
user 0m0.004s
sys 0m0.004s

Al ejecutar Tshark (la versión de consola de Wireshark) puede ocurrir el siguiente error:


carlos@maquina17:~$ sudo tshark -i eth0 -w captura.trafico.20090928.cap
Running as user "root" and group "root". This could be dangerous.
Capturing on eth0
tshark: The file to which the capture would be saved ("captura.trafico.20090928.cap") could not be opened: Permission denied.

Esto ocurre por una cuestión de diseño basada en la seguridad del software (Bug Debian #453292).

Se soluciona de dos formas distintas:

a) Creando previamente el fichero:
carlos@maquina17:~$ sudo touch captura.trafico.20090928.cap

a) Cambiando la ruta donde salvar el fichero a otra donde no haya problemas de UID.
carlos@maquina17:~$ sudo tshark -i eth0 -w /root/captura.trafico.20090928.cap

Si al ejecutar Firefox se produce este error en la consola:

carlos@WhenIGrowUp:~/personal$ firefox
Could not find compatible GRE between version 1.9.0.1 and 1.9.0.*.

Es necesario realizar los siguientes pasos:

1º) Comprobar paquete “xulrunner”

$ dpkg -l xulrunner-1.9
(...)
ii xulrunner-1.9 1.9.0.3+nobinonly- XUL + XPCOM application runner

2º) Instalarlo si no se dispone de él:

$ sudo apt-get install xulrunner

3º) Ejecutar:

$ xulrunner --register-global

Y volver a ejecutar Firefox.

Si al ejecutar la utilidad Web-Shell se producen trazas similares a éstas:

Se debe sencillamente a un uso incorrecto de la aplicación. La web se ha accedido por http cuando debe ser por https.
http://172.26.0.5:8022/
https://172.26.0.5:8022/

Además, si se desea monitorizar con Monit, es necesario añadir las siguientes líneas al fichero de configuración

#sudo nano /etc/monit/monitrc
(...)
check host WebShell_8022 with address 127.0.0.1
start program = "/usr/bin/python /etc/WebShell/webshell.py &"
stop program = "/usr/bin/killall -9 python /etc/WebShell/webshell.py"
if failed port 8022 then restart
(...)

adaptando las rutas, y reiniciar Monit

#sudo /etc/init.d/monit restart

During the installation of Xplico, network traffic analyzer and sniffer (pcap compatible), may happen this error:

#dpkg -i xplico_0.5.2_i386.deb
After this operation, 0B of additional disk space will be used.
Setting up xplico (0.5.2) ...
chown: cannot access `/opt/xplico/xi': No such file or directory
dpkg: error processing xplico (--configure):
subprocess post-installation script returned error exit status 1
Errors were encountered while processing:
xplico
E: Sub-process /usr/bin/dpkg returned an error code (1)

If you create that missing directory by yourself and try to reinstall, another error will be prompted:

root@ubuntu:/home/adminuser/Desktop# apt-get install xplico
chmod: cannot access `/opt/xplico/xplico.db': No such file or directory

Till next package version, the current solution is uninstall and reinstall using this method:

1º) Uninstall:
# sudo dpkg -r xplico

2º) Manually delete the lines which mention port 9876
# nano etc/apache2/ports.conf

3º) Install the package with gdebi:
adminuser@ubuntu:~/Desktop$ sudo apt-get install gdebi

adminuser@ubuntu:~/Desktop$ sudo gdebi xplico_0.5.2_i386.deb

Xplico is a Network Forensic Analysis Tool (NFAT)
The goal of Xplico is extract from an internet traffic capture the applications data contained.
For example, from a pcap file Xplico extracts each email (POP, IMAP, and SMTP protocols), all HTTP contents, each VoIP call (SIP), FTP, TFTP, and so on. Xplico is not a network protocol analyzer.

El formato de backups de Plesk es distinto al habitual tar.gz, por lo que hay que utilizar una herramienta específica para, posteriormente si, conseguir un tar.gz

1º) Bajar, descomprimir e instalar ripmime

2º) Procesar el fichero con ripmine:
# ripmime -i backup-20090908-mi-dominio.com -d directorioBackupRestaurada

3º) Descomprimir el contenido:
# tar -ztvf directorioBackupRestaurada/*
