Timezone incorrect ubuntu

2011-09-01T08:03:00.000-07:00

In case the time zone value shown by ubuntu is incorrect, for example Aisa/Calcutta the correct value is UTC + 5.30 but if your system shows only UTC time then follow the step to correct the time of the timezone.

ln -sf /usr/share/zoneinfo/UTC /etc/localtime

here instead of UTC type the zone that is required.

How to have multiple versions of gcc and switch from one version to other

2011-08-17T01:25:00.000-07:00

First download the gcc packages
for example: cpp-3.4_3.4.4-6ubuntu8_i386.deb (1707096 bytes)
gcc-3.4_3.4.4-6ubuntu8_i386.deb (484408 bytes)
gcc-3.4-base_3.4.4-6ubuntu8_i386.deb (163028 bytes)

mkdir ~/gcc-3.4

cd ~/gcc-3.4

sudo apt-get install build-essential

dpkg-scanpackages . /dev/null | gzip -9c > Packages.gz

sudo gedit /etc/apt/sources.list

add the following code to the file:
deb file:///home/username/gcc-3.4 ./

replace the username with your user name

sudo apt-get update
sudo apt-get install gcc-3.4

Now you have 2 versions of gcc

Now list all the gcc that is available
$ls /usr/bin/gcc* -l

Now type

$ sudo update-alternatives –install /usr/bin/gcc gcc /usr/bin/gcc-4.2 40
$ sudo update-alternatives –install /usr/bin/gcc gcc /usr/bin/gcc-3.4 30

this will set both the gcc versions

now to switch from one gcc version to another perform

sudo update-alternatives --config

Now enter the number of whichever gcc you want.

I believe this will work for other packages also.

How to login to linux/windows without grub

2011-08-14T09:38:00.000-07:00

grub> rootnoverify (hd0,0)

grub> chainloader +1

grub> boot

In case you want the grub screen from the grub command line

grub> configfile(hd0,7) /boot/grub/menu.lst

In case of grub 2.0 then
set root='(hd0, msdos1)'
chainloader +1
boot

Setting up a samba server

2011-07-12T03:15:00.000-07:00

Used for sharing files from linux (ubuntu) to windows

1. sudo apt-get install samba

2. sudo gedit /etc/samba/smb.conf

in smb.conf

security = user

usernamemap = /etc/samba/smbusers

3. now it will take the username from the file mentioned

4. first create a password for the username in the file

sudo smbpasswd -a

Now add the username to the file using the commands

sudo gedit /etc/samba/smbusers

= “”

Now we have to create samba shares and give access (i.e) create some directory in the server and give access to the file so that the windows user can read the shared document

1. open sudo gedit /etc/samba/smb.conf

[global]
 security = share
       client lanman auth = Yes
       lanman auth = Yes

[tmp]
 comment = Temporary file space
 path = /tmp
        read only = n

public = yes

(or)

in the smb.conf (default file)

#======================= Share Definitions =======================
# Un-comment the following (and tweak the other settings below to suit)
# to enable the default home directory shares. This will share each
# user’s home directory as \\server\username
[homes]
comment = Home Directories
browseable = yes
# By default, \\server\username shares can be connected to by anyone
# with access to the samba server. Un-comment the following parameter
# to make sure that only “username” can connect to \\server\username
valid users = %S
# By default, the home directories are exported read-only. Change next
# parameter to ‘yes’ if you want to be able to write to them.
writable = yes

If you are using the first method then

create a directory named /tmp in ubuntu

Finally

In windows machine

go to run and type

//machinename/hostname

here machine name is the hostname of the ubuntu server

You can find the hostname by typing the command

hostname in terminal.

Once the server and client are setup find out if the directory is shared

1. smbclient -L localhost

This will display the name of the folder that is shared

2. How to check whether the folder sharing works properly
mount.cifs //192.168.0.2/tmp /mnt/smb

This command will mount the folder on the location /mnt/smb. If it gets mounted properly then the setup is working properly.

How to install M5sim

2011-05-28T02:05:00.000-07:00

M5 sim installation

1. nrs@nrs-OptiPlex-745:~$ sudo apt-get install g++ python-dev scons swig zlib1g-dev m4 mercurial patch subversion

2. hg clone http://repo.m5sim.org/m5

3. nrs@nrs-OptiPlex-745:~/m5$ scons build_opts/X86_SE/m5.opt
scons: Reading SConscript files ...

You're missing the M5 style hook.
Please install the hook so we can ensure that all code fits a common style.

All you'd need to do is add the following lines to your repository .hg/hgrc
or your personal .hgrc
----------------

[extensions]
style = ./util/style.py

[hooks]
pretxncommit.style = python:style.check_style
pre-qrefresh.style = python:style.check_style

4. The program 'style' is currently not installed. You can install it by typing:
sudo apt-get install diction

during compilation don't use sudo. Simply compile using scons in the given directory.

5. sudo apt-get install diction

6. scons build/ALPHA_FS/m5.debug

7. scons build/X86_FS/m5.debug

8. download the vmlinux files for the respective ISA

9. mkdir /dist/m5/system and extract the files there.

10. now for running the program use
cd ~/m5
sudo ./build/ALPHA_FS/m5.opt configs/example/fs.py

How to install R plot

2011-02-21T21:45:00.000-08:00

Add the following line to /etc/sources.lst

The publisher requires that PDF fonts are embedded so that documents can be printed everywhere; one or more of your document fonts are not embedded.

2010-08-01T22:36:00.000-07:00

Compile the latex by first doing:
Latex
Bibtex (if u have a separate bibliography file)
Latex
Dvi -> PS
PS -> PDF.

Do not directly use:
DVI -> PDF.

This will solve the embedding issues.

Setting and Removing http_proxy in linux

2010-02-04T22:36:00.000-08:00

1. For setting http_proxy
                export http_proxy="http://proxy:port/"

2. For unsetting
                  unset http_proxy=""

Removing http_proxy [ 407 proxy authentication required ] when using synaptic package manager:

Do the following:
1. Remove proxy from Preferences -> Network proxy [ use direct connection ]
2. Remove proxy from synaptic package manager -> preferences -> Network
3. use unset http_proxy
4. export http_proxy=""
           check if proxy is set or not by using: echo $http_proxy
Repeat steps (3) and (4) for ftp proxy also.

5. immediately do apt-get update once or twice
6. If still you get error [407 proxy authentication required]

    goto ~/.bashrc check if http_proxy is set if so remove it.

Please also check if you have changed the file sources.list in /etc/apt folder. If so reverse it back to the old version.
