Server :: Enable A Password Policy For Squirrelmail?
Jul 29, 2011
My organisation is running squirrelmail on a redhat server. When users are created , at that time the admin sets a password. Thereafter the user can login to his account using the password. But he can't change it as is the case with gmail or yahoo mail. Also the password for any account is known to the admin in addition to the user himself - a weak security arrangement !So what I wish to do is provide a way for users to change his password anytime he wants and also during the first login - as is normally done in banking sites, etc

Today i was going through some of security guides written on linux .Under shadow file security following points were mentioned.1)The encrypted password stored under /etc/shadow file should have more than 14-25 characters.2)Usernames in shadow file must satisfy to all the same rules as usernames in /etc/passwd.3)password for application Username should display * if username is not locked.4)If a user is locked it should be displayed as ! as the first character in second field of shadow file.
Confusion for point 1 and 2:Now i m confused as why the encrypted password should be more than 14-25 characters.Also what rules to satisfy How to check it?Confusion for point 3 and 4:There are lot of users with * as second field i guess they are not locked but according to 4th point there are lot of users with ! as first characters.How would i check whether they are actually locked or not.I m posting the output of /etc/shadow and /etc/passwd files for the account.

I am using pam module to set password policy in my SuSE linux machine. This is my /etc/pam.d/common-password file:
Now if root user tries to change the password of a normal user, giving the same password, it is throwing an error saying "Password has been already used. Choose another".
Example:
> passwd user1
> password1 (set successfully)
> passwd user1
> password1 (Password has been already used. Choose another)
This should not happen with the root user.

Ubuntu Documentation > Ubuntu 9.04 > Ubuntu Server Guide > Security > User Management states that there is a default minimum password length for Ubuntu:
Say the password is to be modified by the user using passwd. Is there a command for displaying the current password policies for a user (such as the chage command displays the password expiration information for a specific user)?
This is rather than examining various places that control the policy and interpreting them since the process could contain errors. A command that reports the composed policy would be used to check the policy setting steps.

I am trying to configure my live install of fedora so a PC on the same intranet can access it by hostname instead of by IP address.After I installed bind, I realized the man pages recommended against bind and said instead to enable SELinux named. I tried to guess what variables to set after googling and studying the documentation and coming up empty. I used getsebool -a, and tried turning one and all on.I test using:nslookup myhostname on the linux box, since if that is working it isnt surprising that the windows box cant see it. what buttons to push to enable SELinux named, as described in fedora 13 man page for bin slight correction, the man page is for named. It says to remove the bind-chroot and use SElinux to enable named. I think I also have to create a new zone. This seems akin to proving fermats last theorem but less rewarding. anyone know what keys to push for either. I did get system-config-selinux running. I thought it was in an infinite loop but it does *eventually* load a gui. Also if you set a boolean it will grab all CPU for a couple of minutes. (used top in another terminal).

I was trying to have access from a browser to the squirrelmail configtest page in my server, making some changes, I accidentaly remove the directory webmail. After I replace it with a backup apache2 can not start. This is what I have. Syntax error on line 281 of /etc/apache2/apache2.conf: Syntax error on line 1 of [URL].. closed. But I am sure there is a ?> at the end of this file.Base on what I read on [URL]...-with-the-tag/ I test without the ?> also, but I got the same error.

When try to deployed squirrelmail, configured display language to "Chinese Simp" or "Chinese Trad", it could not display mail folder and reported "Reason Given: GB2312 character set is not supported." Checked locale/zh_CN[zh_TW]/LC_MESSAGES/squirrelmail.po, file charset encode is utf-8, also locale/zh_CN[zh_TW]/setup.php charset to utf-8, but at functions/i18n.php, it used charset of zh_CN/zh_TW to gb2312/big5. after changed it to utf-8, it working fine.However, all messages received is corrupted characters in chinese
Either the title is corrupted characters, or information is corrupted characters.

I am quite new to Squirrelmail but got it working at the first place. Then, with the intention to secure login and data flow, I downloaded and installed the secure login plugin. However, just right after that, I started to get "the connection was interrupted" messages in firefox. I guess that it has something to do with SSL, probably I need to configure that in Apache, not sure. Unfortunately the README and INSTALL files are rather compact in the plugin and I struggle to find a step-by-step tutorial on what needs to be done in order to make it work.Would someone be able to give me a hint on where to find such an information or tell me what else I need to do besides the 3 points written in INSTALL?

i followed this tutorial to the "T", [URL]. I am not able to login to the mailboxes with squirrelmail, it says "connection dropped by imap server" I used the whole address as a login just like it said to do. I can sucessfully authenticate with outlook express but it throws an error that say's [URL], no such file or directory. i can telnet into it remotely but when i type ehlo [URL] it just keeps showing all the 250 lines and wont let me generate a message.
from what i saw on the comments on the tutorial and googling there are many other people with this problem, however i found no solutions. This is fresh work and i have not touched any config files since finishing the tutorial

I am new to linux, just completed with configuring webmin on my new ubuntu server. I have installed myql, acpache etc. Now I wish to install the mail server. With which mail server should I go for the following use and I wish to also use squirrel mail.
The mail server would get connected to my online mail server from where it would fetch up emails and keep it here something like what mdaemon does in windows. And also send emails from this machine using smtp and pop3. How to do this kind of config and the best mail server

When i tried to log in, i get blank screen on the login page, even the src/configtest.php This can be solved by reverting whatever was edited for the motd option to its original paramater. anyone experienced this before and found a solution? The only reason for me to use php 5.2 is to install roundcube alongside squirrelmail. Using: centos 5.5 32-bit, squirrelmail 1.4.8, php 5.2

My company email server has been working flawlessly for the last 5+ years. Recently, one of our clients put their email server behind a firewall (an assumption on my part; details below). Ever since, email sent from within the company (192.168.xxx.xxx internal address; all computers and server is behind a NAT firewall [Netgear FVX538]) is either being sent to the client after some delay (if email is sent using Outlook) or is being deferred until the messages expire (Thunderbird, Squirrelmail, etc.). Email sent to the client from anywhere outside the company (using Thunderbird, Outlook or any other email client) is also delivered without any problems (usually after a short delay).
All other emails to the World are being sent without any problems at all (both inside and outside the company; using any email client or webmail). I did contact the client's postmaster, but the client, being a large government agency, will probably not address the problem (if it is on their side) anytime soon. I am not sure if I can do anything from my end to solve the problem. Ever since the problem with the client began, I added two statements to the postfix configuration file (smtp_pix_workaround_delay_time = 20s and smtp_pix_workaround_threshold_time = 0s); this seemed to a bit - it reduced the delay for emails sent via Outlook to a few minutes (as opposed to 30+ minutes); emails sent using Thunderbird/webmail are still being deferred.
Server details: Dual quad-core processor machine, 32 GB RAM, dual 1 gbps network, running Fedora 14 (64-bit; loosely modeled along the lines of Perfect Server (with ISPConfig2) as described on the howtoforge website). Running Postfix (v. 2.7.1), Dovecot (v. 2.0.9).
Postfix details:
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
body_checks = regexp:/etc/postfix/mbl-body-deny
broken_sasl_auth_clients = yes
command_directory = /usr/sbin
[code]....
I emailed the client's postmaster suggesting they disable smtp fixup. But still, what bothers me now is that Outlook works (both within and outside the company) while Thunderbird, webmail, etc. (used by ~90% of the users) do not. In addition, all email clients from outside the company can send email (authenticated via the company server) to the client without any problems. Is there anything I can do on my end to make non-Outlook clients work within the company (webmail is hosted on the company server; so, it would have an internal address as well)?

To configure webmail in linux5, I�ve followed below procedures:
-Squirrelmail-1.4.2.tar.gz and unzipped under the folder /var/www/html
-cd squirrelmail-1.4.2
-cd config
-within this directory, ./conf.pl
-From main menu, I did choose 2 for domain (i.e. arafapparels.com). This is my official domain
-Then save and exit
-For IMAP setting, I did choose D
-Selected uw and save, then exit
-Then from command line, I wrote chown �R apache.apache /var/www/html/data (I created folder data in the above path)
-I created a folder named as attach to keep attachment in /var/www/html i.e. /var/www/html/attach
-Then typed grep �R apache /var/www/html/attach
-Then typed chmod 730 /var/www/html/mail/attach (Here squirrelmail-1.4.2 directory has been moved to mail directory)
-Then from web browser/Internet explorer, I typed http://localhost/mail/
-Here Username & Password appears. Previously I have created username.
-But when put Username & Password, below error message displays
Error connecting to IMAP server: localhost
13: Permission denied
But I gave permission by chmod 777 /var/www/html/mail and by using 555 but no result.

I recently installed Deluge 1.2.0 from the following PPA:[URL]I using this on two different Linux computers. One is running Linux Mint 8 and the other is running Ubuntu Netbook Remix 9.10. The first time on either computer when I enable WebUI in the Deluge GUI it works fine. However if I ever disable it in plugins section I am subsequently unable to re-enable it (doesn't appear in the side panel again). Rebooting or reinstalling Deluge seems to have no effect.Is this a bug or am I doing something wrong?

I am an absolute Linux Beginner who is being required to do a bit of admin work because the boss just fired the old linux admin. Unfortunately, one of our employees cannot remember her password to her email account and as such I need to reset it on our linux server.What I want to check is that this email account is actually a linux user account and I simply will reset the password for it using the passwd command from the root login. Is that correct?

I have NIS setup to manage all my users, and I have samba set up to share out a directory to the users windows computers - which are part of a corporate domain. I have a requirement to synchronise the NIS password to the Samba password so that when a user changes their password in the Linux environment it automatically updates the Samba password so that the user can simply update the password stored by Windows Explorer.

My problem is quite simple, when I set up squirrelmail I only had one user on the server, and now that I have created new users, I can not log in to their accounts via squirrelmail I am using Maildir System is 10.04 server, running postfix and dovecot. I origionaly set up 'remote' as a user, I can send and recive mail on that account and log into squirrelmail
any new accounts can send email to remote(via outlook/thunderbird), to be seen in Squirrelmail, but get an invalid username/password when I try to log into squirrelmail in short, new accounts can not log into squirrelmail
