uname -a or uname -X (see man uname)
Ubuntu has symlinked /bin/sh to /bin/dash.
dash is a Debian derived light version of bash.
It often breaks scripts that expect the bash shell.
fix:-
sudo rm -f /bin/sh
sudo ln -s /bin/bash /bin/sh
dpkg --get-selections
apt-get <package>
default desktop is ~/Desktop
In a network environment when using vnc, use /usr/bin/kcontrol to change
the path to allow different desktops for different machines/os versions.
e.g. ~/.kdevnc_linux1/Desktop
set screen saver timeout
xset s 3600 1800
changing the xterm title dynamically:-
printf "\033]2; <ttile> \a"
add this line to .cshrc to display <hostname>:<cwd>:-
alias cwdcmd printf '"\033]2;${HOST}:$cwd\a"'
see also 'man tcsh'
To send terminal/xterm output to a log file (typescript):-
unsetenv SHELL
script
~johns/diss/d68/d68 -s dyson.x.map -t > dyson.x.map.size
sort -n -k 3,3 dyson.x.map.size > dyson.x.map.sorted
recursive search using gnu grep:-
ggrep -H -n -i --colour -r <string> --include "*.c" --include "*.cc" *
or using find (with grep/fgrep/egrep/ggrep) :-
find . -name "*.c" | xargs grep -i -n <string>
or
find . -name "*.c" -exec grep -H -n "string" {} \;
find files modified les than 10 minutes ago...
find . -mmin -10
recur <command>
run unix ssh server daemon
cd ~/openssh-3.5p1
sshserv
NOTE sshserv is a shell script file:-
#!/bin/csh
while(1)
printf "sshd\n"
sshd -d -p 1024
end
cd <gnu source directory>

This will install files under...

build & install zlib compression libraries...
cd ~/zlib-1.1.4

make install
build & install OpenSSL encryption libraries...
cd ~/openssl-0.9.6g

Configure --prefix=$HOME solaris-sparcv9-gcc
make install
build & install openssh...
cd ~/openssh-3.5p1
ensure configure finds the ssl include directory...
setenv CPPFLAGS -I/home/bak/include
NOTE - to run on a machine NOT connected to development network,
create a directory /home/bak and use in place of $HOME
setenv HOME /home/bak before running make
($HOME/etc is used to locate ssh_prng_cmds at runtime)
configure --prefix=$HOME --with-zlib=$HOME/lib --with-ssl-dir=$HOME/ssl --with-privsep-path=$HOME/var/empty
make install

Privilege separation user sshd does not exist
This will scan a range of IP addresses looking for ssh servers
build & install libpcap...
cd libpcap-0.7.1
configure --prefix=$HOME
make install
cd scanssh
configure --prefix=$HOME --with-libpcap=libpcap-0.7.1
make install
This needs openssl to be built & installed first.
build & install openssl as described above.
(may need to copy ssl libraries into $HOME/ssl/lib
and ssl includes into $HOME/ssl/include/openssl).
There is a config problem with telnetd.c :-
The function inet_ntop() exists - hence HAVE_INET_NTOP is defined.
AF_INET6 is not defined. This gives a compilation error.
hence need to add:-
#if defined HAVE_INET_NTOP && defined INET6 to telnetd.c line 1090
configure --prefix=$HOME --with-openssl-dir=$HOME/ssl
make install
There are problems with the -fwritable-strings parameter when attempting to build using later versions of gcc.
This parameter was used to get gcc to put constants in data space. It has been removed from gcc 4.0.
Source navigator has not been updated to reflect this change.
Need to remove the parameter from the following files...
snavigator/configure
snavigator/configure.in
libgui/configure
