<div class="moz-cite-prefix">The id seems recoverable from the
w2web.users file. However, the password seems not easily
recoverable (as it should be!) as the perl documentation says
"There is no decrypt function" [1]. Therefore, deleting
w2web.users [2] (or .w2web) is the way to do it.<br>
<br>
First, you might want to backup the .w2web folder. For example:<br>
<br>
username@computername:~/Desktop$ cp -r ~/.w2web ~/.w2web_old<br>
<br>
Or at least, you will probably want to get and write down what the
port and host that are in the w2web.conf file before removing the
.w2web folder:<br>
<br>
username@computername:~/Desktop$ cat
~/.w2web/computername/conf/w2web.conf | grep -E 'port|host'<br>
port=7890<br>
host=localhost<br>
<br>
Next, remember to kill all currently running versions of w2web.
For example:<br>
<br>
username@computername:~/Desktop$ ps -e | grep w2web<br>
4089 ? 00:00:00 w2web<br>
username@computername:~/Desktop$ kill 4089<br>
<br>
For example, my username is user1 and password is 1234. The
username is clearly seen in w2web.users and 9XDKy48uHtMo6 is the
hash for my 1234 password:<br>
<br>
username@computername:~/Desktop$ cat
~/.w2web/computername/conf/w2web.users <br>
user1:9XDKy48uHtMo6<br>
<br>
Just the w2web.users file was removed. For example with:<br>
<br>
username@computername:~/Desktop$ rm
~/.w2web/computername/conf/w2web.users <br>
<br>
Next, I was able set a new id and password, but I used the same
ones again. I also used the port and host that I had before in
the w2web.conf file:<br>
<br>
username@computername:~/Desktop$ w2web<br>

The ttja7f2i1Z72 is the hash for my 1234 password. The password
hash is randomly generate each time, which is why it is different.<br>

<p>Dear Shamik</p>
<p>The userid and password are generated when you start
for the first time the w2web interface by typing in the
unix terminal: <br>
</p>
<p>w2web</p>
<p>If it has been already generated, you have then created
a directory named .w2web which contains configuration
files. <br>
</p>
<p>One easy solution is to remove this directory: rm -f
.w2web</p>
<p>Then type: w2web and answer the questions which will
lead to recreate the directory with the userid and
password you will choose. <br>

<div> I am now try to

Unfortunately I do not know the id & the
