What is wrong and what should I do?
When I login to my machine I can see a BLACK screen and my mouse pointer. This is not happening with other users.Few days ago when I tried login to my machine I noticed this. I can access ssh session and do stuff there but some time I need GUI.I can login fine using other users. This is only happening with one specific user.I have just noticed that if I try loggin with the same user which have issues using NX client it shows us a BLACK screen, then if I open xwin then I can see three new windows top panel, bottom panel and Desktop.

For example:
Code:
adduser john
Code:
adduser --system john
Similarly it seems there are normal groups and system groups. Doing an internet search and reading man pages does not give much information on the whole concept of system and regular user/group.
I am trying to setup forward mails to a user in my linux server to procmail. But that doesn't work. My $HOME/.forward looks like the following

I need to instruct sendmail to accept mails that are destined to users that are not available on my server and then forward those emails to catchall@mydomain.tld.Please remember that i don't want to forward every single mail to catchall user. I just want to forward those emails which would be destined for users that do not exist on my server.i have used define(`LUSER_RELAY', `local:catchall@d.com')but it doesn't seems to work.
View 2 Replies View RelatedWe have an external server that runs HTTP/DB servers for out shop system.Then, there's our local, in-house infrastructure that runs a.. yeah... Exchange 2010.The shop system on the external server needs to send mails to customersrder confirmations, invoices, etc.). seing as sending them directly through the local MTA (Postfix) would cause mail delivery problems because of reverse DNS issues, i've set the Postfix MTA to act as a satellite to our in-house Exchange Server, so the Exchange sends the mail instead, giving recipient mail servers a valid reverse DNS lookup.
Now, mails sent by the (proprietary, uneditable) shop system are relayed correctly and sent to the target e-mail address.My problem is: Mails not sent by the shop system, but by our own PHP scripts which run on that same external servers, are NOT relayed properly.So the Exchange is fine with the mails sent by the shop system, but not the mails sent by our scripts.This is what i get in the mail.log:The successfully relayed mail sent by the shop system:Quote:

I often get responses from people who first say: "Are you sure? You want your network to be exposed to the outside world?" I am not experimenting on a Production Server of NASA or any Security Concern Department. Friends, there is no harm in experimenting on your personal computer or on a test computer which is isolated from the production environment. Look at hackers! What do they do? If they don't know how security is breached then how would they come up with security measures?
If my question reads... "How to let any user perform Administrative Tasks on a Linux System irrespective of his/her privileges on that particular system?" then I would not get the right answers in the first place. They will say... "You are letting everyone destroy your system... are you sure you want to do that?" My question is: Why should we restrict ourselves from experimenting even if it sounds weird to other people?
I give you an example where it is desirable to let an unprivileged user perform certain tasks. You want to know if there are any employees in your office who are storing videos in their home directory and filling up the disk space to a great amount. You have a department called "Command Center or Data Center Operations or Help Desk" call it whatever you would, whose work is to monitor such activities, and you create an account "monitor" for them to monitor such activities but they are not able to do them:

I've been using Ubuntu for quite a while, several years, though several upgrades. Experimented with various things, uninstalled some and various other messy activities. Some things don't work as well as they used to. Sometimes my system crashes, or hangs for a while before coming back. I still get a KDE screen when I shut down, though I attempted to uninstal that desktop. I would like to start over, that is with as little trouble possible to reinstall from scratch. Have to save my user directories, also the directories for my LAMP applications.

View 1 Replies View Relatedthere is a qmail server running in the office. we are using 2 Mb/s dedicated connection with web server along with the ajax based
mail server. we are hearing complains from various users inspite of the fact that the mail server is working fine about MUA's(mail user agents) taking too much time to download the mail.Nowadays there are attachments in most of the mails. the mails in Mb/s mostly take time to download. Now I and my coworkers are thinking of enhancing the bandwidth, but one piece of advice i would like to take from the people here is that if there is any chance that the problem can be from the mail server, where can be the problem and how to end that problem.

I would like to trace a user's activity by monitoring system calls. Is there a way to use strace such that at startup it will begin tracing all system calls? Or is there any other method to automatically trace the system calls used during a user's session automatically without having to call strace manually?

I've come across this rare issue, I have a friend that uses some software that is particularly slow in Windows 7, the best compatibility is in Windows XP, I told him to make a partition and have both OSes in the computer, at which he replied: "Could I have a different OS for each user?", it seemed like a good question to me, so is that possible?, suppose that I login and it boots me to Vista, then I loggout and Linus Torvalds comes and logins and boots him into Ubuntu, he gets bored and logs out, afterwards my friend comes and logs in, booting into XP, summarizing:

View 2 Replies View RelatedI am running Debian Lenny with the default Gnome desktop. When I set up a new user the sound is not available. It says the device in not installed. I have used the Gnome system menu as follows.System, Administration, Users and Groups, then used the add user button and entered the appropriate info. I then went and clicked on the properties button and then the User Privileges section and checked off the "use audio devices" button. Still no sound. When I go to System, Preferences, Sound, Devices, and do the sound tests I get report that device is not installed.
When I am logged in to the user (jon) that I set up when doing the D.Lenny install, the sound on all various media play back works fine.There is one with 1 exception when loged in to this user(jon). I can not get any sound from the system sounds like select check box = toggle .wav, chose menu item = beep, etc. It would be realy nice to know how to repair or configure tis issue as well.under system info, pci devices it lists as follows Multimedia audio controller, Intel Corp 82801FB/FBM/FR/FW/FRW. Mother board is a ECS 915P-A2 and I guess about 2007 or so vintage. 1 G mem installed and a P-4 2.66 chip. It has the sound built in to it. It works fine on WinXP.
