  • Allowing non-admin users to unstick the print spooler

    - by Reafidy
    I currently have an issue where the print que is getting stuck on a central print server (windows server 2008). Using the "Clear all documents" function does not clear it and gets stuck too. I need non-admin users to be able to clear the print cue from there work stations. I have tried using the following winforms program which I created and allows a user to stop the print spooler, delete printer files in the "C:\Windows\System32\spool\PRINTERS folder" and then start the print spooler but this functionality requires the program to be runs as an administrator, how can I allow my normal users to execute this program without giving them admin privileges? Or is there another way I can allow normal user to clear the print que on the server? Imports System.ServiceProcess Public Class Form1 Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click ClearJammedPrinter() End Sub Public Sub ClearJammedPrinter() Dim tspTimeOut As TimeSpan = New TimeSpan(0, 0, 5) Dim controllerStatus As ServiceControllerStatus = ServiceController1.Status Try If ServiceController1.Status <> ServiceProcess.ServiceControllerStatus.Stopped Then ServiceController1.Stop() End If Try ServiceController1.WaitForStatus(ServiceProcess.ServiceControllerStatus.Stopped, tspTimeOut) Catch Throw New Exception("The controller could not be stopped") End Try Dim strSpoolerFolder As String = "C:\Windows\System32\spool\PRINTERS" Dim s As String For Each s In System.IO.Directory.GetFiles(strSpoolerFolder) System.IO.File.Delete(s) Next s Catch ex As Exception MsgBox(ex.Message) Finally Try Select Case controllerStatus Case ServiceControllerStatus.Running If ServiceController1.Status <> ServiceControllerStatus.Running Then ServiceController1.Start() Case ServiceControllerStatus.Stopped If ServiceController1.Status <> ServiceControllerStatus.Stopped Then ServiceController1.Stop() End Select ServiceController1.WaitForStatus(controllerStatus, tspTimeOut) Catch MsgBox(String.Format("{0}{1}", "The print spooler service could not be returned to its original setting and is currently: ", ServiceController1.Status)) End Try End Try End Sub End Class

  • RPC Server Unavailable on Hyper-V cluster when moving resources after the host adapter has failed

    - by Doug Luxem
    On a Windows 2008 R2 SP1 cluster running Hyper-V, a lost network connectivity on the primary host interface. The interface was rapidly flapping up and down, and this was later determined to be caused by a faulty switch port. As this was a clustered server, the host interface was not fault tolerant (seeing as how the whole server was fault tolerant), so connectivity to the host was going up and down. The Hyper-V guests were completely unaffected by the network outage as they used a dedicated trunk on the server separate from the host interface. Additionally, dedicated interfaces for the cluster and live migration networks were fine. In order to diagnose the server, I tried to move all resources (Hyper-V Guests) to other nodes through Failover Cluster Manager. These moves failed with an error RPC Server Unavailable. The only way to move resources was by shutting down the guests, stopping the cluster service on the Node A, allowing other nodes to take ownership of the resources, and restarting the guests. A few other notes: All nodes have Client for MS Networks and File & Printer Sharing enabled on the Cluster and LM networks. Node A was accessible over cluster and LM networks from other nodes (these are private, cluster-only networks); pingable, CIFs, etc. Accessing \\NODEA is done over the Host adapters, as you would expect in this case and is the reason for the RPC Server Unavailable error with that adapter being down. My questions here are - Is there a way to still use Live Migration in a failure scenario such as this to prevent shutting down the Hyper-V guests? How can the network be reconfigured in the future so that the cluster service attempts to use the cluster and/or live migration networks to issue the RPC requests?

  • No LAN and SMB access, and Explorer not responsive, when using a second connection

    - by Lorenzo
    I apologize if this is a duplicate question, I know that there are several questions about multiple connection (LAN + LAN and LAN + dialup) but I haven't been able to find one that fits my scenario. I'm still using Windows XP on my corporate laptop, and I'm connected to the corporate LAN via Ethernet. The LAN NIC has a public IP address, although not accessible externally, obtained via the corporate DNS server. This connection is firewalled and requires a proxy to access Internet. To access Internet sites blocked by the corporate firewall, I use my smartphone via USB tethering. It is seen as a new LAN interface, and I get a private IP address (class 192.168..). There are two problems: The LAN is not accessible, as the default gateway goes to the tethering NIC. I'd like to solve this, but I can live with it. My PC becomes unresponsive if I use Windows Explorer to view local files, or even when I open the start menu. I guess that this is caused by attemps to connect to a mapped network drive. But I disabled the "Client for Microsoft Networks" in the tethering NIC. Why the system still hangs? Of course if I disable the Ethernet NIC, Explorer stops hanging. If you need further details, add a comment. Thanks!

  • Possible Solution for Setting up a Linux VPN Server to Encrypt WLAN Traffic of Macs and iPhones on

    - by GorillaPatch
    I would like to set up a VPN server on debian linux to encrypt wireless traffic coming from my Mac or iOS device. I would like to use a certificate-based solution. Setting up a PKI infrastructure and managing certificates is OK for me. 1. Which server to pick? By looking through the internet and here on stackoverflow I found the following possible solutions: strongSwan IPSec and racoon Which solution is feasible for a linode running debian squeeze? 2. How to configure the network? If I understood correctly a VPN has a virtual network interface as an endpoint on the server side. Naively I would think that I need a DHCP server running on the server to assign a dynamic private IP (like of the class C network 192.168.xxx.xxx) to the connecting clients. Next I think I would need to set up masquerading to NAT the incoming VPN traffic to the real interface directly connected to the internet. Is this the right way to go? Do you have any configuration examples? I often saw VPN configurations used to connect to your home network, but that is not what I am looking for. I have a server up in the internet and want to use it as a proxy to encrypt traffic in insecure network environments like public WLANs.

  • Windows Server 2008 ignores any change made to firewall

    - by Maurice Courtois
    I have been trying for the last 2 hours to make my Windows Server 2008 answer ping. I have tried almost every single solution I have found on the web, so far nothing work. My current setup: 2 NIC (1x Internet connection, 1x Local network) Server act as VPN server. So I set the corresponding NIC as either Public or Private. I also enable the rule for "File and Printer Sharing (Echo Request...)" for all Nic and from any IPs. I always been able to ping from the local network or the local ip while connected to the VPN. I also tried to create a specific rule for ICMP ping and disabling the firewall for all but the public nic. Regardless of all this, I still can't ping that server from Internet. Any idea suggestion what could cause this? I have the impression that when you set the server as VPN (I switch the box on when setting it up to block everything else than VPN connection) that changing anything to the firewall setting thought mmc is pointless !?!?

  • Hyper-V: Dedicated NIC for Guests VMs

    - by TheLizardKing
    I have two NIC cards and created a private virtual network for my virtual machines and unchecked "Allow management operating system to share this network adapter" which basically turns my Guest NIC into this sorta shell of a NIC card on the host machine and the only thing checked in it's properties is "Microsoft Virtual Network Switch Protocol" which I am fine with. Everything works and everything is connected. My issue is that for some reason my guest (Ubuntu Server with legacy network drivers) is not talking properly to my DHCP server. Specifically my DHCP server reserves the guest's IP address using it's MAC address but the guest isn't picking it up. It's picking up any old IP it can get and I can't even ping the hostname from another PC on the network but it pings fine if I use the IP. I see the guest showing up in my DHCP table but I can't get the reservation to stick. Is there some reason it's only partially communicating with my DHCP server? Pinging it's hostname on itself reveals it's using 127.0.0.1 instead of it's network IP. Is this an issue with the legacy drivers used in Hyper-V?

  • Mount EC2 instance via SSH on Mac OS X

    - by darkporter
    OK I just can't figure this out. I have an EC2 instance, which I'm able to SSH into just fine with: ssh -i XXXX.pem [email protected] I can even make it slick from the command line by creating a ~/.ssh/config with this in it: Host XXXX HostName XXXX User ubuntu IdentityFile ~/.ec2/XXXX.pem Which allows me to simple do a ssh XXXX with no -i option. Now, I want to mount this via SSH. I've tried MacFuse/SSHFS, MacFusion and ExpandDrive, but no luck. It's supposed to "just work" but the SSH-related command line utilities and the Keychain Access program in OS X is confusing and opaque to me. From what I've read, these GUI programs don't care about .ssh/config, they care about the Keychain. Somehow I can associate my domain name I'm connecting to with a particular "identity" private key file (.pem file) but I have no idea how. I tried this: ssh-add -K XXXX.pem Which does add to the Keychain but it's not associated to a particular domain. These GUI mounting programs I mentioned all just spin and do nothing when I try to connect passwordless. No keychain prompt, no nothing. I've pretty much given up and I'm thinking about just setting up an SMB server, but I'd rather just go over SSH since I believe it's possible.

  • How to set umask globally?

    - by DevSolar
    I am using a private user group setup, i.e. a user foo's home directory is owned by foo:foo, not foo:users. For this to work, I need to set the umask to 002 globally. After a quick grep -RIi umask /etc/*, it seemed for a moment that modifying the UMASK entry in /etc/login.defs should do the trick. It does, too -- but only for console logins. If I log in to my desktop, and open a terminal there, I still get to see the default umask 022. Same goes for files created from apps started through the menu. Apparently, the display manager (or whatever X11 component responsible) does source some different setting than a console login does, and damned if I could tell which one it is. (I tried changing the setting in /etc/init.d/rc, and no, it did not help.) How / where do I set umask globally (and for all users), so that the X11 desktop environment gets the memo as well? (The system is Linux Mint / Ubuntu, in case that changes anything...)

  • Sign multiple domains with single Domain Key (dk-filter)

    - by Lashae
    Motivation The private shopping website GILT, send periodical update emails from giltgroupe.bounce.ed10.net however all of the mails are signed with domain keys of giltgroupe.com. mailed-by giltgroupe.bounce.ed10.net signed-by giltgroupe.com My Story I couldn't manage to sign x.com with y.com 's domain key using dk-filter under Debian Lenny with postfix. If I try to init dk-filter service with following arguments: DAEMON_OPTS="$DAEMON_OPTS -d x.com,y.com -c nofws -k -i /var/dk-filter/internal_hosts -s /etc/dk-keys.conf" dk-filter service signs with domain x.com (d=x.com) If I change the daemon arg.s as following: DAEMON_OPTS="$DAEMON_OPTS -d x.com -c nofws -k -i /var/dk-filter/internal_hosts -s /etc/dk-keys.conf" then emails sent From y.com is not being signed. the dk-keys.conf file is as follows: *:/var/dk-filter/y.com/mail I managed to do same thing with DKIM, works perfect. However DK doesn't seem to work. I don't have any problem signing y.com's emails with y.com's key and x.com's emails x.com's key, which indicates there is no configuration problem. Do you have any experience/advice to make it possible to sign emails from multiple domains by a specific chosen domain?

  • Switch to IPv6 and get rid of NAT? Are you kidding?

    - by Ernie
    So our ISP has set up IPv6 recently, and I've been studying what the transition should entail before jumping into the fray. I've noticed three very important issues: Our office NAT router (an old Linksys BEFSR41) does not support IPv6. Nor does any newer router, AFAICT. The book I'm reading about IPv6 tells me that it makes NAT "unnecessary" anyway. If we're supposed to just get rid of this router and plug everything directly to the Internet, I start to panic. There's no way in hell I'll put our billing database (With lots of credit card information!) on the internet for everyone to see. Even if I were to propose setting up Windows' firewall on it to allow only 6 addresses to have any access to it at all, I still break out in a cold sweat. I don't trust Windows, Windows' firewall, or the network at large enough to even be remotely comfortable with that. There's a few old hardware devices (ie, printers) that have absolutely no IPv6 capability at all. And likely a laundry list of security issues that date back to around 1998. And likely no way to actually patch them in any way. And no funding for new printers. I hear that IPv6 and IPSEC are supposed to make all this secure somehow, but without physically separated networks that make these devices invisible to the Internet, I really can't see how. I can likewise really see how any defences I create will be overrun in short order. I've been running servers on the Internet for years now and I'm quite familiar with the sort of things necessary to secure those, but putting something Private on the network like our billing database has always been completely out of the question. What should I be replacing NAT with, if we don't have physically separate networks?

  • Linux CentOS strange memory readings

    - by user2008937
    I am actually a young junior sys admin. I have a question - i am trying to understand how linux deals with memory... while playing around different monitoring programs I found some strange thing. When I run top on my laptop it shows me that FIREFOX process with pid 8778 takes 18,3% of memory (%MEM column). grep "MemTotal" /proc/meminfo Above command give me 1848336kb/1024 = 1805megs of memory (its ok - i have 2 gigs of ram). So if the firefox process takes 18,3% of MEM(according to tops %MEM column) then it takes 0.183 * 1805 which is approximately 325mb of memory. Quite a lot as for firefox... But well, in Linux there are lots of shared libraries that programs commonly uses (like famous libc). And those libraries are added to memory utilization of every process that uses it in the system, despite they are actually reading same file(single object in memory). So top may show too big mem utilization because of those shared libraries. Well, it is time to use PMAP which should show us the real mem utilization of process. But.. pmap -d $(pidof firefox) mapped: 983460K writeable/private: 757164K shared: 66416K so pmap shows that 983460/1024=993MB of memory is mapped to this process. It is in fact much bigger than mem utilization showed by top. Whats wrong here? How pmap can show more than top? even when top adds also the shared libraries (which in fact are single objects in memory) for each process that uses it? and pmap omits it? Regards Krzysztof

  • How to set up hosts file for local environment?

    - by n00b0101
    I'm trying to create subdomains on my localhost and am way out of my territory... I'm running MAMP on my Mac OS X and I thought/think I had/have to do the following: (Assuming I want to create me.localhost.com and you.localhost.com) (1) Edit /private/etc/hosts Right now, it looks like this: 127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost So, do I just make it: 127.0.0.1 localhost 127.0.0.1 me.localhost.com 127.0.0.1 you.localhost.com 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost (2) I'm assuming I don't need to mess with DNS at all because it's local? So, the hosts file should suffice? (3) And then, I need to edit my httpd.conf file to include virtual hosts? I tried this, but it's not picking it up... NameVirtualHost * <VirtualHost *> DocumentRoot "/Applications/MAMP/htdocs" ServerName localhost </VirtualHost> <VirtualHost *> DocumentRoot "/Applications/MAMP/htdocs/me.localhost.com" ServerName me.localhost.com </VirtualHost> <VirtualHost *> DocumentRoot "/Applications/MAMP/htdocs/you.localhost.com" ServerName you.localhost.com </VirtualHost> Not sure if I'm way off-base here...

  • The best way to hide data Encryption,Connection,Hardware

    - by Tico Raaphorst
    So to say, if i have a VPS which i own now, and i wanted to make the most secure and stable system that i can make. How would i do that? Just to try: I installed debian 7 with LVM Encryption via installation: You get the 2 partitions a /boot and a encrypted partition. When booting you will be prompted to fill in the password to unlock the encryption of the encrypted partition, Which then will have more partitions like /home /usr and swapspace which will automatically mount. Now, i do need to fill in the password over a VNC-SSL connection via the control panel website of the VPS hoster, so they can see my disk encryption password if they wanted to, they have the option if they wanted to look at what i have as data right? Data encryption on VPS , Is it possible to have a 100% secure virtual private server? So lets say i have my server and it is sitting well locked next to me, with the following examples covered bios (you have to replace bios) raid (you have to unlock raid-config) disk (you have to unlock disk encryption) filelike-zip-tar (files are stored in encrypted archives) which are in some other crypted file mounted as partition (archives mounted as partitions) all on the same system So it will be slow but it would be extremely difficult to crack the encryption. So to say if you stole the server. Then i only need to make the connection like ssh safer with single use passwords, block all incoming and outgoing connections but give one "exception" for myself. And maybe one for if i somehow lose my identity for the "exeption" What other overkill but realistic security options are available, i have heard about SElinux?

  • Isolating Apache virtualhosts from the rest of the system

    - by JesperB
    I am setting up a web server that will host a number of different web sites as Apache VirtualHosts, each of these will have the possibility to run scripts (primarily PHP, possiblu others). My question is how I isolate each of these VirtualHosts from eachother and from the rest of the system? I don't want e.g. website X to read the configuration of website Y or any of the server's "private" files. At the moment I have set up the VirtualHosts with FastCGI, PHP and SUExec as described here (http://x10hosting.com/forums/vps-tutorials/148894-debian-apache-2-2-fastcgi-php-5-suexec-easy-way.html), but the SUExec only prevents users from editing/executing files other than their own - the users can still read sensitive information such as config files. I have thought about removing the UNIX global read permission for all files on the server, as this would fix the above problem, but I'm not sure if I can safely do this without disrupting the server function. I also looked into using chroot, but it seems that this can only be done on a per-server basis, and not on a per-virtual-host basis. I'm looking for any suggestions that will isolate my VirtualHosts from the rest of the system. PS I'm running Ubuntu 12.04 server

  • Does anyone know how to "tcpdump" traffic decrypted by Mallory MITM? [migrated]

    - by chriv
    I'm looking for some help in capturing network traffic that I can analyze in Wireshare (or other tools). The tool I'm using is mallory. If anyone is familiar with mallory, I could use some help. I've got it configured and running correctly, but I don't know how to get the output that I want. The setup is on my private network. I have a VM (running Ubuntu 12.04 - precise) with two NICs: eth0 is on my "real" network eth1 is only on my "fake" network, and is using dnsmasq (for DNS and DHCP for other devices on the "fake" network) Effectively eth0 is the "WAN" on my VM, and eth1 is the "LAN" on my VM. I've setup mallory and iptables to intercept, decrypt, encrypt and rewrite all traffic coming in on destination port 443 on eth1. On the device I want intercepted, I have imported the ca.cer that mallory generated as a trusted root certificate. I need to analyze some strange behavior in the HTTPS stream between the client and server, so that's why mallory is setup in between for this MITM. I would like to take the decrypted HTTPS traffic and dump it to either a logfile or a socket in a format compatible with tcpdump/wireshark (so I can collect it later and analyze it). Running tcpdump on eth1 is too soon (it's encrypted), and running tcpdump on eth2 is too late (it's been re-encrypted). Is there a way to make mallory "tcpdump" the decrypted traffic (in both directions)?

  • Limited connections to Ubuntu 12.04 server

    - by Luis M. Valenzuela
    I'm having a weird problem with my server. The server is inside my network, connected to a 3com switch which is connected to the router that handles the internet connection. The main purpose of the server is to host a php application. What's happening is that user 1 to 15 in the private network have no problems connecting to the server, when user 16 tries to connect a time out comes out and is unable to connect to the server. It's not just to the php application, but to any service from the server. When the 15 users are using the application, the server doesn't even answer to ping. I haven't set any special limit in Apache's ini file or MySql and the firewall is being turned off because the server is only to give service to the internal network. Is there a parameter in any of the network's card conf. files that might me causing this ? Or should I suspect from the router's or switches configuration ? UPDATE. Tomorrow, I'm gonna do some test on the server modifying two kernel params in : /etc/sysctl.conf The settings are: net.core.somaxconn which has the limit on simultaneous network connections to the server and kernel.shmmax which controls the amount of memory the system can use for managing connections.

  • Vyatta masquerade out bridge interface

    - by miquella
    We have set up a Vyatta Core 6.1 gateway on our network with three interfaces: eth0 - 1.1.1.1 - public gateway/router IP (to public upstream router) eth1 - 2.2.2.1/24 - public subnet (connected to a second firewall 2.2.2.2) eth2 - 10.10.0.1/24 - private subnet Our ISP provided the 1.1.1.1 address for us to use as our gateway. The 2.2.2.1 address is so the other firewall (2.2.2.2) can communicate to this gateway which then routes the traffic out through the eth0 interface. Here is our current configuration: interfaces { bridge br100 { address 2.2.2.1/24 } ethernet eth0 { address 1.1.1.1/30 vif 100 { bridge-group { bridge br100 } } } ethernet eth1 { bridge-group { bridge br100 } } ethernet eth2 { address 10.10.0.1/24 } loopback lo { } } service { nat { rule 100 { outbound-interface eth0 source { address 10.10.0.1/24 } type masquerade } } } With this configuration, it routes everything, but the source address after masquerading is 1.1.1.1, which is correct, because that's the interface it's bound to. But because of some of our requirements here, we need it to source from the 2.2.2.1 address instead (what's the point of paying for a class C public subnet if the only address we can send from is our gateway!?). I've tried binding to br100 instead of eth0, but it doesn't seem to route anything if I do that. I imagine I'm just missing something simple. Any thoughts?

  • Macvlan based interface pings from host but not from namespace

    My setup: Private network vboxnet1 10.0.7.0/24 1 Host, ubuntu desktop 1 VM, ubuntu server (VirtualBox) Adressing layout: HOST: 10.0.7.1 VM: 10.0.7.101 VM MAC NAMESPACE: 10.0.7.102 On the VM, I ran the following commands: ip netns add mac # create a new nmespace ip link add link eth0 mac0 type macvlan # create a new macvlan interface ip link set mac0 netns mac On the mac namespace, inside the VM: ip link set lo up ip link set mac up ip addr add 10.0.7.102/24 dev mac0 So that we basically end up with: (Like Inception ?) +------------------------+ | Host: 10.0.7.1 | | | | +--------------------+ | | | VM: 10.0.7.101 | | | | | | | | +----------------+ | | | | | NS: 10.0.7.102 | | | | | | | | | | | +----------------+ | | | +--------------------+ | +------------------------+ What works: Ping between Host and VM Ping between NS and NS dhclient from NS What does not work: ping between NS and VM ping between NS and Host Where I started to go nuts: tcpdump on host (the real machine) actually shows ARP request AND replies tcpdump on NS shows ARP requests sent to the host tcpdump on VM makes the whole mess work (!) -- ping starts to get answers when tcpdump is started on the VM ?!? So, I bet you were eager for it, my question is: how to I make it work ? I suspect something's wrong with ARP on the macvlan inside the NS but can't figure out what exactly... Btw, I did the same expérimentations with the mac0 interface directly on the VM (no namespace) and it worked flawlessly.

  • How to use basic auth for single file in otherwise forbidden Apache directory?

    - by mit
    I want to allow access to a single file in a directory that is otherwise forbidden. This did not work: <VirtualHost 10.10.10.10:80> ServerName example.com DocumentRoot /var/www/html <Directory /var/www/html> Options FollowSymLinks AllowOverride None order allow,deny allow from all </Directory> # disallow the admin directory: <Directory /var/www/html/admin> order allow,deny deny from all </Directory> # but allow this single file:: <Files /var/www/html/admin/allowed.php> AuthType basic AuthName "private area" AuthUserFile /home/webroot/.htusers Require user admin1 </Files> ... </VirtualHost> When I visit http://example.com/admin/allowed.php I get the Forbidden message of the http://example.com/admin/ directory. How can I make an exception for allowed.php? If not possible, maybe I could enumerate all forbidden files in another Files directive? Let's say admin/ contains also user.php and admin.php which should be forbidden in this virtual host.

  • Why not block ICMP?

    - by Agvorth
    I think I almost have my iptables setup complete on my CentOS 5.3 system. Here is my script... # Establish a clean slate iptables -P INPUT ACCEPT iptables -P FORWARD ACCEPT iptables -P OUTPUT ACCEPT iptables -F # Flush all rules iptables -X # Delete all chains # Disable routing. Drop packets if they reach the end of the chain. iptables -P FORWARD DROP # Drop all packets with a bad state iptables -A INPUT -m state --state INVALID -j DROP # Accept any packets that have something to do with ones we've sent on outbound iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT # Accept any packets coming or going on localhost (this can be very important) iptables -A INPUT -i lo -j ACCEPT # Accept ICMP iptables -A INPUT -p icmp -j ACCEPT # Allow ssh iptables -A INPUT -p tcp --dport 22 -j ACCEPT # Allow httpd iptables -A INPUT -p tcp --dport 80 -j ACCEPT # Allow SSL iptables -A INPUT -p tcp --dport 443 -j ACCEPT # Block all other traffic iptables -A INPUT -j DROP For context, this machine is a Virtual Private Server Web app host. In a previous question, Lee B said that I should "lock down ICMP a bit more." Why not just block it altogether? What would happen if I did that (what bad thing would happen)? If I need to not block ICMP, how could I go about locking it down more?

  • Juniper SSG20 IP settings for email server

    - by codemonkie
    We have 5 usable external static IP addresses leased by our ISP: .49 to .53, where .49 is assigned to the Juniper SSG20 firewall and NATed for 172.16.10.0/24 .50 is assigned to a windows box for web server and domain controller .51 is assigned to another windows box with exchange server (domain: mycompany1.com) mx record is pointing to 20x.xx.xxx.51 Currently there is a policy set for all SMTP incoming traffic addressed to .51 forward to the NATed address of the exchange server box (private IP: 172.16.10.194). We can send and receive emails for both internal and external, but the gmail is saying mails from mycomany1.com is not sent from the same IP as the mx lookup however is from 20x.xx.xxx.49: Received-SPF: neutral (google.com: 20x.xx.xxx.49 is neither permitted nor denied by best guess record for domain of [email protected]) client-ip=20x.xx.xxx.49; Authentication-Results: mx.google.com; spf=neutral (google.com: 20x.xx.xxx.49 is neither permitted nor denied by best guess record for domain of [email protected]) [email protected] and the mx record in global dns space as well as in the domain controller .50 for mail.mycompany1.com is set to 20x.xx.xxx.51 My attempt to resolve the above issue is to Update the mx record from 20x.xx.xxx.51 to 20x.xx.xxx.49 Create a new VIP for SMTP traffic addressed to 20x.xx.xxx.49 to forward to 172.16.10.194 After my changes incoming email stopped working, I believe it has something to do with the Juniper setting that SMTP addressed to .49 is not forwarded to 172.16.10.194 Also, I have been wondering is it mandatory to assign an external static IP address to the Juniper firewall? Any helps appreciated. TIA

  • Nginx Ubuntu Postfix Config - Can't connect to incoming IMAP server 'server not responding' but can send mail via outgoing using same details?

    - by daveaspinall
    I'm pretty to new server admin and especially nginx but seem to be getting ok fine apart from accessing my mail via my iPhone? I've changed my domain to 'domain.com' The thing is I can send mail via my outgoing IMAP server but can't connect to the incoming one? I just get the message "the mail server at mail.domain.com is not responding" /etc/postfix/main.cf alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases append_dot_mydomain = no biff = no broken_sasl_auth_clients = yes config_directory = /etc/postfix home_mailbox = Maildir/ inet_interfaces = all inet_protocols = all mailbox_command = mailbox_size_limit = 0 mydestination = domain.com, mail.domain.com, localhost.com, , localhost, localhost.localdomain mydomain = domain.com myhostname = mail.domain.com mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 myorigin = /etc/mailname recipient_delimiter = + relayhost = smtp_tls_note_starttls_offer = yes smtp_tls_security_level = may smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = smtpd_sasl_security_options = noanonymous smtpd_tls_CAfile = /etc/ssl/certs/cacert.pem smtpd_tls_auth_only = no smtpd_tls_cert_file = /etc/ssl/certs/smtpd.crt smtpd_tls_key_file = /etc/ssl/private/smtpd.key smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes smtpd_tls_security_level = may smtpd_tls_session_cache_timeout = 3600s tls_random_source = dev:/dev/urandom telnet localhost 25 ehlo locahost 250-mail.domain.com 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-AUTH LOGIN PLAIN 250-AUTH=LOGIN PLAIN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN Using the following details to connect: username password hostname: mail.domain.com port: 25 iptables --list Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination I also sent mail to the server as a test and got this missage if it helps? Technical details of temporary failure: [mail.domain.com. (10): Connection refused] I also looked in /var/log/mail.log and it has multiple entries of: postfix/smtpd[12239]: connect from 5acefc9a.bb.sky.com[90.206.252.xxx] Mar 23 06:47:09 new-domain postfix/smtpd[12239]: lost connection after CONNECT from 5acefc9a.bb.sky.com[90.206.252.154] Notice new-domain which is incorrect but the server hostname and hostname in the configs are correct? I recently moves servers and the host has set the primary domain on the service as new-domain.com so this may be the issue? Like I said, it works to connect to outgoing server, but incoming gets the not responding error? Any idea would be much appreciated!
