Ubuntu Servers :: 9.10 Server - How To Setup Remote Desktop / VNC Via SSH + Command Line

Feb 21, 2010

I am playing around with the idea of being able to use a cloud or instance based service to install Ubuntu 9.10 Server. This will enable me to have remote access via SSH command line.So far, I've installed Ubuntu 9.10 Server + Ubuntu Desktop to a virtual machine. I can access this via SSH and locally via the desktop. However, in the real environment the only access I am going to have initially is via SSH.

I would like to be able to connect using Windows Remote Desktop or VNC (whichever is easier and most importantly - most secure) to the machine.. even though the desktop is on there, I need to somehow configure the remote access all from the command line.I've had a read of various forums and have been trawling support forums for days but can't find a working solution for 9.10 Server or that fits my situation above where I will not have any physical access to the desktop or machine to configure remote desktop. It all has to be done via SSH/command line.

Ubuntu Servers :: Exim4 Forwarding To Local Host

Jun 9, 2010

I've recently had to rebuild our mail server - after the old one over heated - and I've realised I never backed up the config files for exim... so now tyring to work out how the hell to configure what I had....

The setup isn't the most straight forward, so I'll try and explain what happens...

- all emails @longdomain.com are received by an hosted server on the internet
- they are then forwarded to @shortdomain.com, the IP for which is our internet connection which fowards port 25 traffic to the exim server
- the exim server then spam and virus checks the emails and forwards them to an exchange server (sorry but it works well for us)....

I've installed exim4/spamassassin/clamav successfully, and it's setup to receive emails for the relevant domains and relay from the hosted server on the internet (and some local addresses).

how I then setup exim4 to foward all emails on the relevant domains to the exchange server?

Ubuntu Servers :: Could Not Perform Immediate Config On Exim4-daemon-light

Jan 20, 2011

I'm more of a CentOS person, but after some issues on my new box I switched to Ubuntu server. I am working on getting it setup as a mail server (mainly for testing at the moment and soon be live). I performed apt-get install sendmail then apt-get install exim4 and got the message:Could not perform immediate configuration on 'exim4-daemon-light'. Please see man 5 apt.conf under APT:: Immediate-Configure for details. I have Ubuntu Server 10.10 32-bit on a Dell Intel Poweredge.

Ubuntu Servers :: Exim4 Sends Mail Correctly, But Wrong "from" Address?

Apr 5, 2010

I have a ubuntu server 9.10 installed with exim4 as MTA. I configured a mail address on it (let's say me@example.com). Before i had it working i had a other email configured (let's say me_2@example.com). At the time i had this one it didn't work i removed exim4.

Now i can successfully send mails with it by the configured me@example.com. I also configured the password for this, but when i receive the mail the old configured mail is presented as "from" (so from: me_2@example.com).

Anyone knows how this can be changed so it says the mail is from me@example.com? The mail is not an alias, and in a mail client they work separately.

Server :: Postfix Request Port 587 - Can't Email Via Work Account - IPhone Or Residential Internet

Jun 21, 2011

I got a request today from someone on the software development team that reads as follows: Quote: According to RFC 4409 client mail submission to an email server is supposed to use port 587. Server to server SMTP relays are to use port 25. When I am not on site, I can't email via my work account via my iPhone or my residential internet because my ISP(s) filter port 25 to only allow traffic to and from their mail servers. They do however allow 587 anywhere per RFC 4409. Just to send this email I am having to relay off my own server in California. get the proper ports opened on the mail server? [URL] So my question now is I'm wondering if my Postfix server isn't properly configured? Right now it's listening on the following ports:

Ubuntu Servers :: Setup New Remote Office - Setup Domain Trust Between Two Sites?

Mar 14, 2010

I ended up setting up a basic linux file server as a pdc for that office. Our main office is a windows 2000 ads domain. The two offices are connected with a vpn. I only have two users at the new location so I simply have the linux and samba usernames/passwords setup manually. I would like to know if it is possible to setup a domain trust between the two sites so I don't have to create a username/password in the remote site for every user at the main office to access. I did some searching but came up empty.

Ubuntu Multimedia :: Setup Audacity To Record From Line-in?

Mar 5, 2011

I am trying to get Audacity to record from a line in. Seems like it should be a fairly easy setup. I discovered that Audacity needs PulseAudio. So I installed that, and don't know how to configure it. I set the sound preferences >> Input to line in. I am using a desktop that has a line-in on the front and back, so I'm not sure which it will pick up, so I have been testing both.

Ubuntu Installation :: Cmd Line Access To Panel - Drawer Setup In Gnome?

Aug 18, 2011

I am looking for a way to programmatically (Python or shell) set up my panels, drawers, app launchers and stuff. Just wondering if there is a way to do that - or a standard approach to it and such.

Am using Gnome - the regular install - no extra components or such. Would it be easier to do it if I was using Gnome 3. Just putting the question out there in case someone is using Gnome 3 and it would be easier to do the automated setup in Gnome 3.

General :: Command Line Email (Gmail) Setup

Sep 18, 2010

I am pretty new to C.L.I/text editing work. So maybe its a bit old-fashioned but I am interested in learning how to send email via the command line. I am running 10.04 32 bit

Situation: I have followed the explicit and step-by-step actions at http://klenwell.com/is/UbuntuCommandLineGmail

Question: Upon completion, when trying to send a test email to myself via gmail (from CLI) I get the following error: "msmtp: no recipients found". In CLI below it asks me to explicitly pick a mailx to download. I think I already have mailx as when I type mailx I get "no mail for primary".

Here is my work
Code:
:~$ sudo apt-get install msmtp mailx
[sudo] password for:
Reading package lists... Done
Building dependency tree
Reading state information... Done
msmtp is already the newest version.
Package mailx is a virtual package provided by:
mailutils 1:2.1+dfsg1-4ubuntu1
heirloom-mailx 12.4-1.1
bsd-mailx 8.1.2-0.20090911cvs-2ubuntu1

You should explicitly select one to install.
E: Package mailx has no installation candidate
:~$ gedit ~/.msmtprc
:~$ chmod 600 ~/.msmtprc
:~$ gedit ~/.mailrc
:~$ echo -e "testing email from the command line" > /tmp/test_email
:~$ mailx -s "mailx gmail test" xxxxxxx@gmail.com < /tmp/test_email

CentOS 5 Server :: Setup Printer From Command Line?

Feb 24, 2009

I'm from a Solaris (printer.conf) background and having trouble setting up a printer on the network. My CentOS box does not have a GUI interface available. I have been playing with lpadmin trying to add a printer - which it did, but everything is disabled, and the "enable" command is not found on my machine.

How do I make a simple printer on my network talk to my centOS box?

Here's the printer.conf from a Solaris machine that works:

raphael:
:bsdaddr=igppps1,raphael,Solaris:
And the printers.conf from the CentOS box:
lumina# more printers.conf
# Printer configuration file for CUPS v1.2.4

Debian :: How To Remove Exim4

May 20, 2011

I'm running a Squeeze minimal install. I don't need exim4, which got installed with the base net-install (I think). So I did

#apt-get remove exim4

and it said it had done it. However, recently I noticed during bootup that there was a line that said "Starting MTA: exim4". Then, another time I did apt-get update and apt-get upgrade, and it wanted to upgrade three exim4 packages. So I thought "Hmm- exim4 must have come back." However, apt-get remove exim4 gets a "It ain't installed" (or words to that effect) response. "Find exim4" gets a list of about 40 files, including /usr/sbin/exim4, /usr/lib/exim4/ /usr/share/exim4, /etc/init.d/exim4, and a whole raft of config and man files. I've done apt-get purge exim4, and I'm now at my wits end- what on earth is going on? Can't apt-get do it? Might Aptitude (never used it) do it? (Don't have Synaptic installed- I try to keep as minmal as possible, it's an old machine.)

Debian Installation :: 8.0 - Setup Boots GRUB Command Line

May 2, 2015

I wanted to install Debian 8.0 on my second hdd in my UEFI machine, but when I choose UEFI boot from USB, GRUB command line appears, and I cannot boot up the setup. I used Rufus to create the bootable USB stick, using the amd64 kde CD image. I tried several images and I deleted the Linux and Efi partitions from previous installation of Ubuntu . Also I deleted GRUB from the Windows 7 Efi partition.

In the UEFI setup fast boot and secure boot are disabled, and I don't seem to have the option to boot in legacy mode, if I choose the simple USB boot option (without "UEFI" in front) I get "please insert correct boot media, and press any key or reboot". I couldn't manually boot from GRUB command line, because it is showing that all the drives are empty, and if I type "boot" I get "please load the kernel first".

Fedora X86/64bit :: Cannot Change Services With 'setup' Command Line In F10 (64-bit)

Jul 8, 2009

The problem relates only to the configuration of services in text mode ("setup", part of the setuptool package). The setuptool package is "setuptool-1.19.4-2.fc9.x86_64". There is no "Services configuration" menu when I start "setup". The tools listed in the setup window are:

- Authentication configuration
- Firewall configuration
- Keyboard configuration

[code].....

IMHO, the reason I don't have a services configuration tool is the missing services configuration files "98services" and/or 99"services" (or something like that) from the setuptool's configuration directory. (Please correct me if I am wrong.) Can someone please let me know what information should be in those two files, and what are the correct file names? Without them I cannot change the services on this computer. (FYI, the GUI (system-config-services) works, however, I need to run this computer in text mode.)

Debian :: Aliases Not Working In EXIM4?

Oct 28, 2010

I recently P2V'd a debian box, and the aliases file (/etc/aliases) is no longer working. As the physical machine is still working, this machien has been renamed to buzz1 [from buzz].

I changed /etc/mailname, /etc/exim4/update-exim4.conf.conf [and ran the update-exim4.conf script] and also ran newaliases. however it still does not seem to be applying the aliases file:

Live Physical Machine:
buzz:~# exim -bt root@buzz.domain.com
R: system_aliases for root@buzz.domain.com
R: smarthost for cronjobs@domain.com cronjobs@domain.com
<-- root@buzz.domain.com

Debian Multimedia :: SOUND - Line In Works But Doesn't Appear In Gnome Setup

Jun 4, 2015

I am runnig Jessie with the default GNOME. Every thing has been perfectly smooth, but for the audio line in. First you should now the same hardware was working well with Wheezy. Then the hardware card is RealTek ALC887-VD and I am using the analogic part (both for in and out lines).

Below I will write some command results, but first, it seems important to describe the problem. I can hear the audio line in. If I blow in a mic, I definitelly hear the sound of it in the output. With alsamixer I can toggle the line in level and it works fine. By the way, with pavucontrol, it is the same I have access to the line in. but when I look in the Gnome setting for the sound, input, no card is available, then no volume setting is available.

--> as a result, I can't record the sound from the mic. it is sent directly to the output without been taken into account in the system. So no comment on video making, no skype …

On the web, the problem is always "no sound with this card" "No sound after upgrade to Jessie"… but Card is working fine but no seen on a upper level…

Code: Select allroot@Desktop:~# lsmod |grep snd
snd_hda_codec_realtek    67127  1
snd_hda_codec_generic    63142  1 snd_hda_codec_realtek

Networking :: Send Local Mail From Exim4 And Other To ISP

(Desktop with Debian sid) How do I configure Exim4 to send local mail locally and other mail through my ISP? I just did dpkg-reconfigure exim4-config and none of the choices seemed to give me the answer. I have a lot of frozen email addressed to:
root@<My_ISP_SMTP_URL>. I also don't know what happens to regular email sent from Mutt. I have no problem sending email through my laptop on the same LAN.

General :: Debian & Exim4 Configuration Php Mail

Aug 27, 2010

Linux [URL] 2.6.26-2-686 #1 SMP Wed Feb 10 08:59:21 UTC 2010 i686 GNU/Linux Currently I have exim4 configured to use my mail server as a relay to send php emails. Though I don�t think I want this setup. My goal is to be able to track emails sent out to make sure that nothing happened and they got bounced back. I need to be able to find the emails that are bounced.

If I configure exim4 to send emails from the current (apache2 / php) server any emails that bounce will end up there, correct? We have clients that are expecting emails and are complaining they do not always get them so something is not 100% configured correctly. I am going to re-run #dpkg-reconfigure exim4-config

Software :: Exim4 Forward Emails Not Working?

May 4, 2011

Running exim4 on debian and trying to forward all emails destined for root@mydomain.com to me@mydomain.com, I did setup the entry in the /etc/alias file in the following way:

root: me@mydomain.com

run newaliases restart exim "although not needed if I am not mistaken"

then on command line mail root@mydomain.com and the email still goes out for root@Mydomain.com and not me@mydomain.com I am using a smarthost, and that smarthost refuses to serve emails going for root@. I am OK with that as I should be able to easily rewrite those message to go to me@mydomain.com

But it is simply not working, anything I might have missed here ?

Debian Configuration :: Exim4 Public Not Requiring Any Authentication

Jul 9, 2015

I've installed it properly until it works now, it does send emails and receive them, but heres the problem.

1) it does not send emails to a certain domain, unless i do dpkg-reconfigure on exim4 and put the domain on allowed relay... can't i just put something on settings which allow to send emails to ALL domains?

2) EVERYONE can connect to the server by telnet from any position, terminal or pc, and just use an existing user to send emails to anyone.... example, i have testuser123 setted up in debian/exim4 .. then they simply write "mail from:testuser123@host.dot" and the server accepts it.. without even request an authentication for that. And this is a problem, because everyone can use my email addresses to send emails to whoever.. heaven for spammers/hackers..

Debian Configuration :: Exim4 With Domain In Local Network

Sep 3, 2015

I'm trying to set up a *simple* MTA in my local network. The only thing it should be able to do is send system / daemon mails to admin@mylocaldomain. but at the moment I'm pretty much overwhelmed by everything i *should* know in order to set up this MTA

my infrastructure:

- servers:
* test01.mylocaldomain --> should send mails (with exim) to admin@mylocaldomain
* dns01.mylocaldomain --> dns-server
* mail.mylocaldomain --> mail-server (postfix / iredmail package)

I configured exim to be in "internet"-mode. now i have a variety of errors I can choose from (and a variety of solutions that i don't like ).. my test is always an email from test01.mylocaldomain:

echo "Hello World" | mail -s Testmail admin@mylocaldomain

- after running the config, i get the error: admin@mylocaldomain: all relevant MX records point to non-existent hosts --> google says, edit and udpate update-exim4.conf.conf --> dc_relay_domains='mylocaldomain' --> but this exim installation should not be a relay at all. it should only be able to SEND (to this domain), not deliver it. or do i get something wrong?

- after i added dc_relay_domains='mylocaldomain', i get --> SMTP error from remote mail server after RCPT TO:<admin@mylocaldomain>: host mail.mylocaldomain [192.168.x.x]: 550 5.1.1 <root@mylocaldomain>: Sender address rejected: User unknown in virtual mailbox table --> but i don't want to create an account on the mailserver for the SENDER...

- ...so i thought, i'd config exim with the domain "test01.mylocaldomain" (including the server name), so that the sender is clearly from another domain than the mail server handles (e.g. user@test01.mylocaldomain).. but then i get this --> SMTP error from remote mail server after RCPT TO:<admin@mylocaldomain>: host mail.mylocaldomain [192.168.x.x]: 450 4.1.8 <root@test01.mylocaldomain>: Sender address rejected: Domain not found

I really just wanna send mails in my local network.

Debian Configuration :: Root Attacks Due To Security Breach In Exim4?

Jan 21, 2011

My debian server has been attacked due to a security breach in exim4 4.69-9 (probably applies to loads of other versions too). The security breach allows the attacker to get root access by creating a buffer overflow in a header which then can be used to inject code.

[URL]

The securtiy breach is fixed with 4.69-9+lenny1 I want to share my actions with you on what I did to (hopefully) get rid of it. However at the time of writing this, the above website is down due to too much load (DDOS Attack?). How you can check if you've been attacked:

The attack creates a buffer overflow in exim4, which results in paniclog entries.

$ cat /var/log/exim4/paniclog
2010-12-17 07:34:11 string too large in xxxyyy()
2010-12-19 10:42:10 string too large in xxxyyy()

this would be an example of two attacks. One on 2010-12-17 and the other two days later 2010-12-19.with this information you can start find potentially infected files. There may be a better way, but I searched for them with this command:

$ find / -mtime 31 2>/dev/null # files,directories,links created 31 days ago (i.e. 2010-12-17)

My infected files:

/usr/bin/uptime
/usr/bin/pwdx
/usr/bin/slabtop
