I have exim setup on squeeze to run as an "internet site". Outgoing mail works fine but it seems to just ignore incoming smtp requests on port 25. I can see the incoming connection via tcpdump but exim doesn't seem to talk. If I connect via telnet it rather quickly says connection refused. Is there something additional I need in the Exim conf?

Then alot of random text
I run OSX on my everyday computer so this is not me sending out stuff since the above mail says Microsoft Outlook express has sent it (?) Running a Debian Squeeze server. And I really dont get any other spam due to exim4u setup and spamassasin.
I have defoptions=quiet in my menu.list file and it keeps printing
ignoring bad line 1 'powernow-k8' across the screen during boot. The thing is that I have removed that line from /etc/modprobe.d/options, so why do I keep getting the warning?
How can I configure Postfix to reject connections coming from anywhere except the local machine?
View 4 Replies View RelatedI'm trying to follow the exim documentation to allow suffixes on mailboxes for all users. For example, if user@domain is a mailbox, I want all mail directed to user-*@domain to be delivered user@domain. I've got the split-config-files option and have edited /etc/exim4/conf.d/router/600 to include local_part_suffix lines as follows:

I cannot get exim4 to actually deliver any "local delivery only; not on a network".But whatever I do in the config, all mail gets frozen with entries in the log file like:"root@empty R=nonlocal: Mailing to remote domains not supported"Maybe the problem is that there is no fqdn for the computer (and will never be). How can I enable local mail delivery?

View 5 Replies View RelatedI'm trying to setup VNC on our debian server so the boss can remotely do admin stuff from anywhere in the world. the first step is getting it working from anywhere in the room, though. And I can't even seem to get that far.
So far I have a VNC server setup, although not without problems. I downloaded and installed vnc from the vnc site, that wouldn't work because trying to start a vnc server gave this error: "error while loading shared libraries: libstdc++-libc6.2-2.so.3: cannot open shared object file: No such file or directory"
There are lots of results on google for this error, and the solution everywhere seems to be the same. to install the package: libstdc++2.10-glibc2.2
However, trying to install this package in debian fails. both using apt-get and trying to manually download it from packages.debian.org it just doesn't seem to exist.
I've tried tightvnc from the official repositories and it gives the same error, too.
The way I got around that eventually, thanks to another tutorial, was to install the package vnc4server. then run vnc4passwd to create a password. and after that vncserver works fine, or seems to. Creates display 1.
Now, when I'm trying to connect to hostname:1 from another computer in the LAN. It gives error 10061, connection refused. I installed the debian and I don't recall setting it up to refuse connections on port 1. Is there anything I should check or change to allow the connection, or any log file in debian to check and see what's going wrong?
I'm also trying connecting internally via client on the debian machine, but I can't runvncviewer. I get the same missing shared library error as before. I guess I just worked around, not solved it.
I also can't access it with the java viewer. Trying to connect on port 5801 either from the server itself, or from another one on the lan, tells me it's refusing the connection.
To be clear, I'm certain that the vnc server is started. We have working DNS, and trying to connect directly to the internal IP:1 doesn't work either.
For some reason my FTP packets are blocked by iptables even though I thought I allowed them through
My syslog errors are along this line:

A little background: CCNA and A+ I have preformed this task on Cisco routers Linux for 5+ years, mostly with Debian (mostly casual, a few production situations) I need to setup a linux box with Load Balancing over a cable line 8mb down, 1mb up connection and a T1 line. If this isn't possible, at the very least I need Failover (which I have admittedly not researched as fully.) I know Failover is possible, but I would really love to double my upload bandwidth as we host a small website here. Is load balancing over uneven connections possible on Debian?
Side question: If I host a website, when users connect and get responses over 2 Public IP's, what would be the reaction on the users side? Would it get filtered and or blocked by a firewall?
I want to limit the amount of connections a user can make outside of the box per user group, should I be doing this via iptables or what? aka:
group1 can only have 2 simultaneous outbound connections
group2 can only have 8
My Debian server is used by people to set up ssh-tunnels for use as a local proxy ( on their remote machines).Since only the tunnel is setup, and no shell is used, I can't use "who" to see which users have an active ssh-tunnel on my server, but I would like to have an idea about who is active etc. I think I should be able to determine this from the auth.log file, but then I would have to use some script to determine what connection is still active. Is there an easy way to see what users have active ssh-tunnels on my Debian server at any given moment?

Using Debian 6 on eeePC1000HEB with Ath9k (i think) wireless card. Net Interface: wlan0
I am still a noob with linux and debian in particular. I do some android development so through that I have learned a little bit about linux but only the basic command prompt commands and the basics of how linux works and such.Anyways, I was looking around on the forum and on other forums and I couldn't find any helpful information about how to set up wireless connections (such as wifi) on debian. When I installed debian on my computer it asked me for the ipw2200 files and I didn't have them at the time but now I have the latest framework files for that, I don't really know how to install them and after I install them I don't know how to turn on my wireless connections from there.
I am really sorry if someone already made a post on this subject and I am just too clutzy to find it, if that's the case please just post the link to that thread for me cause I'm dumb as crap.So basically the main problem I am trying to fix right now is that I cannot get my internet to work on my old dell inspiron 6000 laptop which I am trying to get to run debian.
My employer has started the process of certification with Return Path, and I've been roped in to setting up DKIM, SPF, SenderID etc. so that we are compliant with the certification requirements. Our current e-mail server is qmail, and I'm really not too keen on messing about with the configuration files there. As a safer alternative, I've decided to set up a smarthost relay that only does the DKIM signing. I tried and gave up on Postfix - struggled with understanding the configuration files - and eventually found Exim.
Now, I've got the relaying working perfectly so far. I am NOT running an open relay, my smarthost is configured to only accept SMTP connections from the existing mailserver, and not publicly accessible anyway. The problem I'm having is figuring out exactly where in exim's configuration file I am supposed to configure the DKIM signing options. I've read the official exim documentation and I'm fairly sure about the syntax, I just can't figure out where the options go.
I'm in the process of starting a migration from an old postfix server to nice shiney new exim server however there are a few things i'm really not clear on and i'm hoping that some one here could point me in the correct direction. Okay the postfix server at the moment does the follwoing ( i'll try and keep this simple ):
* accepts incoming mail for users on multiple domains and puts the mail in the users mailbox ( external -> internal )
*accepts mail from users on multiple domains to pass on to the outside world ( internal -> external )
Obviously the POP and Imap functions are handled by other daemons.. I'd like to replicate this sort of setup on the new exim box, however the guides i can find only help with configuring the exim system for incoming mails ( external -> internal ) for multiple domains and i cant seem to find a guide that would indicate how to do both ( internal -> external and external -> internal ) on one box. I'm guessing i may have to do some sort of auth to get exim to accept and then handle the internal -> external side of things?
I have a problem copying my udev rules from other distro to another pc running debian. My box is running debian without any DE and I want my USB disks to be automounted based on the label; I believe udev is the nicest way to do this task.
Anyways : my rules are (copied from archlinux wiki btw)
cat /etc/udev/rules.d/92-my-media-automount.rules

I notice the directory is made successfully up inserting the usb HD, but the mount doesn't succeed. If I manually execute above command, the mount goes ok.
I'm trying to set up an SSD as a cache to my external HDD (which is where my installation of Debian testing/stretch is installed). My installation is using LVM 2. I'm trying to have the SSD cache the entire external HDD, and not just one of the partitions (such as the root or home partitions).

Must I "operate" on this drive via a live session or something.
Recently (in 2015) our Debian systems started not to recognize HDDs connected via an external docking station.
On my computer I run: (uname -a)
* Linux violin 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt9-3~deb8u1 (2015-04-24) x86_64 GNU/Linux
* If I connect to a flashdrive to the USB2 port, it is recognized as sd* (messages are also written to dmesg/syslog)
* If I connect the USB3 connector of the external docking station with an 1TB WD SATA docked, to this USB2 port (the external docking station has its own power supply, so I do not expect to have a problem with the current, the drive spins up and is spinning), there is nothing in the dmesg/syslog, and no new items under /dev/sd* or lsusb or similar tools.
* If I connect the same external docking station with the same disk via eSATA on a different computer it is recognized. That computer runs the same debian. If I connect through its USB2 port it does not work either.
* I also tried another docking station and USB cable.
i want if a port (exp. 1001) have 20 connections that the next new connection forword to an other port (exp. 1002).
View 2 Replies View RelatedI'm running Debian 8.2 and trying to set up so I can plug in a couple of external hard drives that will be used to sync data between systems using rsync.
I've got the rsync bit working how I want, thats not a issue. But what I can't seem to get to work properly is when I plug the devices in, they don't mount automatically.
I've tried various methods to no avail so far, systemd.automount in fstab doesn't seem to want to work, for some reason it gives a I/O error. I've tried setting up udev rules and they don't work either, so I'm a bit of a loss now.
Not sure what info to provide that would be relevant at this time, but can add logs as required easy enough.
This machine is headless, so command line only suggestions would be best. I can access X via the network if I have to, but I'd rather do it by cli for ease of access.
My fstab file
Code: Select all# /etc/fstab: static file system information.

# Use 'blkid' to print the universally unique identifier for a

I have successfully mounted my Win7 volume and my external hard drives NTFS volume as well. However, after modifying the fstab I seem to only be getting the win7 volume to auto-mount. Below is the contents of my fstab. /dev/sdf3 is not mounting. Again, it works no problem if I manually mount it.

I got this bounceback recently and I'm unsure of how to correct the problem. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error.

What's interesting is that in some places the correct domain is given, but the return-path and the envelope-from are set incorrectly. I should add a few things: this machine is used only to send email newsletters and for email generated by the websites; staff email is handled elsewhere the output of hostname is myhost the output of hostname -f is myhost.mydomain.net when I ran dpkg-reconfigure exim4-config, I set the system mail name to "localhost" so as to "'qualify' mail addresses without a domain name." I have a feeling this is the source of my problem, but when I set this to mydomain.net, I ran into another problem: I essentially disabled local mail. Messages to root (e.g., the results of cron jobs) would show up in my logs as root@mydomain.net. I want local mail to follow the rules set forth in /etc/aliases, not be converted to local-account@mydomain.net.
It's been awhile since last dealt with Debian.
I'm setting up mail server on Debian 5.04
So I need exim4-daemon-heavy, I removed exim4-daemon-light and can't find heavy, in fact can't find any exim package.
I have Debian and I see that exim is installed on it. I want to make my own home mail server, but with postfix. Do I have to remove exim first and then install potfix or what?
View 1 Replies View RelatedMy laptop has a dual boot Debian + Ubuntu installation.
In particular I am using Debian 8.0 with stock kernel 3.16.0-4 (or equally 4.1.10 custom compiled, I tested it and it does not make any difference for the subject of this post).
Ubuntu is 14.10, with stock kernel 3.19.0-15.
In both installations I have nvidia nouveau drivers and intel integrated graphics drivers installed and loaded. This is the default for both installations.
In both installations I have xorg automatically configured (no xorg.conf file present in /etc/X11). In both systems the content of /usr/share/X11/xorg.conf.d is the same for what moitors are concerned (differences in mice and trackpad entries).
Unfortunately, the video configuration in Ubuntu 14.10 works out of the box. In particular I can plug in an external monitor/projector and it will fire-up the nvidia card (nouveau drivers) to power that monitor.
Debian 8.0 on the other hand does not even detect the external monitor.
I don't know where to start to solve the problems.
The hardware is as follows: the laptop (lenovo W530) features both an Intel integrated graphics card and an Nvidia K1000M. The VGA port is connected only to the Nvidia card (this is according to my online research, as I don't know how to check this).
When I plug in my external USB Hard drive which is formatted as a single NTFS partition, it is recognized and mounted automatically, a nautilus window pops open. Unfortunately it is not writable. The reason is: the partition is mounted "ntfs" (which lacks write support) instead of "ntfs-3g". This is the output of mount after plugging in the drive:
$ mount | grep sdc1
/dev/sdc1 on /media/4EBC5FB82435B0EE type ntfs (rw,nosuid,nodev,uhelper=devkit,uid=1000,gid=1000,dmask=0077)
I want this partition to be writable by just plugging it in.
The partition should not have any errors because a) I fsck'ed it windows and b) mounting it manually works:
$ sudo mount -t ntfs-3g /dev/sdc1 /media/disk_/
$ mount | grep sdc1
/dev/sdc1 on /media/disk_ type fuseblk (rw,allow_other,blksize=4096)
$ devkit-disks --mount-fstype ntfs-3g --mount /dev/sdc1
Mounted /org/freedesktop/DeviceKit/Disks/devices/sdc1 at /media/4EBC5FB82435B0EE
$ mount | grep sdc1
/dev/sdc1 on /media/4EBC5FB82435B0EE type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096)
$ gnome-mount -nbtd /dev/sdc1
$ mount | grep sdc1
/dev/sdc1 on /media/disk type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096)
How can I get ntfs drives to be mounted as writable by default, preferrably without having to modify fstab?
After logging into a fresh Debian 5.0 (lenny) install from a VPS (virtual private server) provider, I run 'apt-get update' and then 'apt-get upgrade' in attempt to get all the security updates, assuming that's what said commands do. Along the way exim (exim4) and possibly other programs (not confirmed) gets installed and is setup to run on bootup...despite it not being installed previously. Why is this? I would expect that either 1) previously uninstalled pkgs are not installed with the 'upgrade," or 2) if 'upgrade' essentially performing a "install everything that's not already installed" maneuver, I wonder why it's not installing a LOT more packages (then just the view I see installed on my system during the 'upgrade.')
Separately: can someone confirm an 'apt-get update' followed by apt-get upgrade' on a fresh Debian 5.0 install system will basically upgrade to 5.0.8 ("current rev level" for lenny)?
