When installing these progs on Lucid it comes with exim4,I noticed this in the terminal output. What has exim4 to do with rkhunter and/or chkrootkit?

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.)
I've got a problem with my usb pen drives. If I put some data inside, from the 2nd time I insert the pendrive in the computer I can't write on the usb pen, I can't change my files, and also they are hidden. I've formatted them with the format/partitioner tool in yast, but I can't solve my problem. This happens with all my usb pendrives and also with the sd of my camera. Is there something that I can do to solve this inconvenient?

View 3 Replies View RelatedLinux [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
Problems with launching data files of the nas and saving to them is a kde problem. The dot desktop files have to contain access rights for smb/http etc and even when given these it still will not work. I have mainly concentrated on getting the VLC video player to work as it is capable of playing from just about any source, comes with codecs etc etc. Amazing package really.
Pure K apps such as kwrite at least work fine. I tried setting up samba but to no avail.
As dropping a file into VLC's focus didn't do anything I created a vlc desktop icon and dragged the nas file onto that. It plays and a kde error message pops up from plasma shell - can't find file!
I enable kde automount. The content of that when it starts is disturbing. It shows my system disks a detachable and not attached! No need to worry though. I selected mount on log in and attachment where the server was shown. VLC still wouldn't work.
Next I enable NFS file transfers on the NAS. This has allowed me to use open with directly onto an avi file on the nas. I can also click launch them. Remaining problem is opening files on the nas from within VLC. Up pops the kde message "you can only select local files". The file manager here seems to be an instance of dolphin. This suggest that there is going to be a problem saving files to the nas as well. Looks to be the case. VLC can convert formats and all sorts of things. If I select a file locally and try and convert it and save to the nas up pops the "you can only select local files" as soon as I select ok having set the path and file name.
Strange thing is that working transfers seem to be using CIF even though it took an NFS enable to get it partly working via KDE's automount. Dolphin only allows a CIF set up which has a distinct advantage as a direct ip address can be entered. The automount has introduced a very very long delay before kde is up and running following a log in. Samba is even worse in this respect and both seem to lack a method of direct ip input which means they have to find the server.
One other aspect. As far as NFS is concerned from a very recent post elsewhere nautilus works. Pass on CIF. And of course it's all instantaneous and ok on windows even on vista. Enabling the TV protocol on the nas has confused Vista as it only wants to connect like that and needs drivers. Might also be down to having NFS enabled though. MS might not like that.
I have filed all of this on bugzilla if anyone would like to vote - bug number 695648. Seems to me that the CIFs route should be the default for ease with many users on home networks. I'm also sure that the problem is basically KDE preventing aps from accessing the nas.
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..
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.

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

a friend of mine is doing a small website-project in school (group of ~6 people). They want to use git as VCS and need acces to a server. I have an account on the server from university, but - of course - no root access.
I could create private/public keys for them, to SSH into my account, but I don't want them to have this power I found 'git-shell', which seems to be used for restricted access with git (although I'm not sure whether I understood the functionality).
My question is: Is it possible to configure SSH keys in that way, that the server runs them (and only them) in git-shell in a specified directory (using ~/.ssh/{config,authorized_keys})?
So that they can
- log in with their SSH key
- use git, execute scripts etc.
- use git push/pull from their private+school PC
- work only in a specific directory (like chroot) eg. ~/web-project/

Using exim4 only for sending email SMTP
I'd like to use Exim to remove the line header:
Received: from [111.111.111.111]
by HOSTNAME with esmtp (Exim 4.69)
what setting i should use and where should i put it in the exim4 configuration file, transport, router etc.
When I run an exe-File, I become the message: -bash: ./a.out: Keine Berechtigung (No rights)
I have all Rights on the Folder and on the file. I suppose that the problem is that my group "Benutzer" has no rights to execute files. Where can I change the rights of my group?
I am the only user and will not add any more users. What I would like to do is configure to allow me access everything with no "insufficient rights" messages. Further, I would like to be able to operate the GUI in the root user mode when desired.

I am working on a Debian 2.6.26-19 Distribution with exim4 as MTA. After a system restart a problem occurred with delivering emails to local addresses. These local addresses use a 1and1 mailserver for email. The MX records for the local domain are set correctly but exim does not use a DNS lookup for these addresses because it identifies them as local addresses. I figured this out by executing the exim4 -d -bt command. The dns lookup part of the result looks like this (I replaced the actual address with placeholders):
[Code]....
The eventual result of the exim4 -d -bt command is: [user]@[domain.ext] is undeliverable: Unrouteable address How can I make sure, that exim4 makes a DNS lookup for the local addresses instead of skipping it? I know that I have to edit a exim4 configuration file, but I could not figure out which and how.
I would like to install a more modern version of GNU utils (coreutils) on a debian linux system where I have no admin rights. Is there a way to do that?
The rationale is that I need a more modern version to the one installed in the system where I intend to run my analysis. I am trying to use "sort -R" or "shuf" to randomize lines in a big text file.
When i open applications which need su or gksu commands sometimes a string "Granting rights" appears in the window. I just find this [URL] It happens mostly when i use desktop launchers to run these applications.

I have tried to install exim4 and then to purge exim4-daemon-light but
that fails too.
How do I get rid of all exim4 stuff?
(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.
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 ?
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?
