I have fetch mail in my root directory like this:
set no bouncemail
set postmaster postmaster@dot.com.gh
set logfile /var/log/fetchmail
poll pop.teledataict.com
protocol pop3
localdomains dot.com.gh
archive dot.com.gh
no dns
envelope X-Envelope-To:
qvirtual dot.com.gh
user "maildot3@teledataict.com" there
pass "mail"
is *
here forcecr
nokeep
flush
dropdelivered
fetchall
This works perfectly as I want. But right now, what I want is, I want fetchmail to download mails for more than one or several accounts in different domains and different pop servers. How can I improve this rc file to accomplish my task?

How do I add an account so I can access my mailbox from M$ Outlook from a Windows 7 machine?I am planning on using my ISPs smtp server for sending mail.Or is there anything else I should be aware of?http://www7.pic-upload.de/21.04.11/ieg6wv3qx6g.jpg
I am looking at creating two user accounts for "contract system admins"..These guys will be performing sys admin duties for a sever -- however, I am still concerned about security of data. For example, the server contains password information for our database, etc.Besides making them sign an NDA, etc. what other security mechanisms could I put in place to ensure that they don't just go buck wild. For example, when someone makes a sudo command, is this logged?
what are some recommendations for general security practices?
I have a server with a static IP that I use as a sendmail server. The problem is that port 25 is exposed. As a result, anybody can login to the SMTP server and send mail from my domain as a user that does not exist as well as email from other non-existant domains. I'm sure there are sendmail options that I can enable to do some checks, like if the user exists on that server or if the domain is the same on the server, etc. I was wondering if you guys can mention a few that I can add to my sendmail.mc file?
I have thought about auth login, the problem is if auth login is on my public port then I won't be able to receive email from gmail because it would be unauthenticated. Also, I only have 1 mail server. I know the ideal solution is to have 2 mail servers. One for outgoing mail/internal mail server where you can enable auth login and the other for incoming mail which just acts as the relay to the internal mail server. That way spammers can't login to send mail out. That's another question I had, how do I configure sendmail to only send email out/in?
Anyhow, so I have to make do with 1 mail server for now. So I decided to add a few rules on iptables. I grabbed the IP range that gmail uses when I receive mail from then and added it to my iptables with the following command.

I have been using a cron job to duplicate a folder into another users account every day and someone suggested using symbolic links instead although I cannot get them to work. In summary user GAMER generates log files that they want to access via HTTP, however I only have a web-server in the user account SERVER, in the past I would copy the logs folder from GAMERS account into SERVER/public_html/. and then chmod the files so the server could access them. Trying to use symbolic links I set up a link from root (as only root can access both accounts) I used: ln -s /home/GAMER/game/logs/ /home/SERVER/public_html/logs
However it seems that only root can use this link, I tried chmoding the link, all the files in the gamers /game/logs/*, /game/logs itself to 777 as well as changing chown and chgrp to server the files still cannot be read. When viewed from servers account my shell shows the link and where it is to hi-lighted in black with red text. /home/GAMER/game/ (chmod & chgrp) drwxrwxrwx 3 SERVER SERVER 4096 2011-01-07 15:46 logs

I am trying to figure out a way to pull the user information from local users on a Linux server. I have approximately 40 servers running SUSE and Ubuntu that are using Microsoft Active Directory in order to authenticate. Our internal auditing group has made us disable root ssh ability, I was doing this with clusterssh, but I can login as me then su on the server to conduct root, admin, work. This is an ongoing request to get the local users and it is a painfully slow process since I have to login to each server to get the /etc/passwd file. Is there another way to get the local user information? They are now asking about seeing the last logon date or if the account is disabled, any thoughts there as well?Most of our auditors think Windows and I am trying to make my life easier but not sure what options I have. I need to get local accounts and if they are active or disabled plus last logon date. I'm sure there will be more but if I can get the basics adding more shouldn't be too difficult but I guess I'll cross that bride when I get there.
View 7 Replies View RelatedI have couple of users in one machine. I can access the /etc/passwd,/etc/shadow and /etc/group files in this box. I have another box. I want to create some user accounts in the second box by just looking in the passwd, shadow and group files in the first box. I would just copy over the corresponding lines into the corresponding for whichever accounts I want to create as new and also change the lines for which I want to update the account information. Is this possible and will also the passwords work fine? Please also let me know there is any good tool for automatically doing this kind of stuff. Both the boxes that I have are Ubuntu machines though one is running Ubuntu 8.04 and the other is 10.04.

If user1's main group is genetics and one wants to add him/her to group biochem and to assign biochem as his/her secondary group will the following suffice ?
Code:
$ sudo usermod -G biochem user1
I would like for user1 to have genetics as the main group but also belong to biochem. When user1 creates a file, as he/she belongs to main group genetics, I assume the file will be owned by user1 and group owner will be genetics. Ideally files created by user1 should be accessible to users in group genetics(when permissions are tweaked) but not by individuals in group biochem. However, any files with group owner biochem should be accessible to user1 as he/she does belong to biochem as a secondary group. Would having user1 main group genetics, secondary group biochem fulfil this criteria ?
I am currently running a apache/postfix email service on my server. I am using aliases for two addresses for example:
trscookie@serverone.com
trscookie@secondserver.com
so the emails no matter which domain receives the email trscookie always will receive the email.
However I am unable to work out how to 'reverse' this process, for example.
If i was to go to secondserver.com/webmail I would like the emails to get sent from trscookie@secondserver.com however they are currently all coming from serverone.com. Is it possible to configure this so that it is sent from the correct domain?
Here is my main.cf:
queue_directory = /var/spool/postfix
command_directory = /usr/sbin
daemon_directory = /usr/libexec/postfix
mail_owner = postfix

I'm installing a new laptop for a friend of mine and he wants 3 user accounts, similair to how he runs his windows setup.
1, an admin account, we have called this account peacemaker.
2. his account
3. an account for his girlfriend.
The problem we have is that if we want to do anything from the terminal that requires elevated priviledges, sudo does not accept his password or that of peacemakers. we have done sudo -i -u peacemaker but it still doesn't accept either password, stating his account is not in the sudoers list.
I'm not a massive expert here, but research brought me to this page:[URL]... But that then just means his account has admin rights, which is what we were trying to avoid. We wanted a setup similair to windows where if you want to run someting with elevated privledges if pops up asking for the admin password. This works in the gui, but not in the terminal.
So in short, my question is, is there anyway of having the terminal accept peacemakers user rights from the his normal user account? If I add the account to the sudoers list like it suggests, does this again just give his account the prilvedges rather than saying supply me with the password for peacemaker.
this is probably not really needed and he can just have his account as the main user, but coming from a windows background, he would prefer the 3 user accounts model (2 normal users, 1 admin)

View 2 Replies View RelatedWe have a web server and are trying to meet a clients requirementes around accountability.Basically, everything in the system should be accomplished using user accounts that are individually identifiable. So basically, no root user, since that's anonymous.So how should we set up these user accounts?Being administrators, we want them to have easy access to files not owned by them, such as ones uploaded using FTP accounts or via apache.We want to be as secure as possible though.
My current thought is to add them to the root group so they have full read access throughout the system, and add them to sudo, but I worry that gives them too much control.

I've just rebuilt a server that had SLES10 to Slackware64 13.0. I wanted to keep all users and their passwords, so I copied all user entries in the old SLES /etc/passwd and /etc/shadow files to the corresponding new Slackware files. It turns out that the passwords are not interpreted correctly. I presume that SLES uses a different hashing function than slackware. Is there an easy way to convert these hashes, or will I have to reset all passwords and force users to change at login?

View 4 Replies View Relatedway to automate adding and removing users from 10 different Fedora 7 servers. We use them as print servers and our users have a user name and password to authenticate with when printing. We also use Samba to talk to a W2k3 server that tracks and charges the users for what they print. The set up was done by a vendor and after 6 months of being in production the scripts they created has flaws.
I need a way for a script to run as often as possible that will remove, change, or delete user accounts from the servers and from Samba. how to most effectively achieve this?
It would be ideal to have a file that gets written to when a change needs to be made then a script to make these changes?
My Linux is Fedora release 13. I found there are a few users created not by me. I am not sure if the system got hacked somehow. Then the hackers created these users, i.e. (1) oracle, (2) exim, (3) test, (4) cox. I tried to delete all of these four users by using "usrdel" command but the system said "I cannot delete these users as the users are logging in". If my system got hacked ?? or these users are created by the system itself?

I'm having a CentOS 4.4 X86_64 server. Without any warning all users account including root got disabled. As the server was still logged in as root, i was able to enable all the users account. But for root i couldn't.Without thinking i rebooted the server and except root, other users can log in to the server. I should've tried to enable root account from the /etc/passwd. But now i realize its too late for that.Now i want to change from root: x:0:0:root:/root:/bin/false to root: x:0:0:root:/root:/bin/bash. Can anyone guide me to accomplish this or is there any other way to fix this?
