  • postfix and iRedMail- Relaying Denied

    - by Lock
    I am trying to setup iRedMail and am way over my head here. I have installed it, and can send emails internally, but not externally. When I send an email from outside, I get the following return email: The error that the other server returned was: 550 550 5.7.1 <[email protected]>... Relaying denied (state 13). Now I have no idea where to start looking! Any ideas? I have really only just installed iRedMail so I am unsure what else I need to do to get it working. I've pointed my MX records to that server, so that shouldnt be the problem. Also- if i stop postfix (so nothing is listening on port 25) and send a test email, I get the same reply back. Why would I get the same reply back even if postfix is stopped? I have run tcpdump over 25 and can see the packets coming in/out, so its definitely a configuration issue! I suppose my question is not really "what is my problem", but more "What configuration needs to be completed on postfix and iRedMail?"

  • Configure IIS Web Site for alternate Port and receive Access Permission error

    - by Andrew J. Brehm
    When I configure IIS to run a Web site on Port 1414, I get the following error: --------------------------- Internet Information Services (IIS) Manager --------------------------- The process cannot access the file because it is being used by another process. (Exception from HRESULT: 0x80070020) However, as according to netstat the port is not in use. Completely aside from IIS, I wrote a test program (just to open the port and test it): TcpListener tcpListener; tcpListener = new TcpListener(IPAddress.Any, port); try { tcpListener.Start(); Console.WriteLine("Press \"q\" key to quit."); ConsoleKeyInfo key; do { key = Console.ReadKey(); } while (key.KeyChar != 'q'); } catch (Exception ex) { Console.WriteLine(ex.Message); } tcpListener.Stop(); The result was an exception and the following ex.Message: An attempt was made to access a socket in a way forbidden by its access permissions The port was available but its "access permissions" are not allowing me access. This remains after several restarts. The port is not reserved or in use as far as I know and while IIS says it is in use, netstat and my test program say it is not and my test program receives the error that I am not allowed to access the port. The test program ran elevated. The IIS Site is running MQSeries, but the MQ listener also cannot start on port 1414 because of this issue. A quick search of my registry found nothing interesting for port 1414. What are socket access permissions and how can I correct mine to allow access?

  • How can I disable DNSSC for Google Apps (GMail) MX records on my authoritative domains?

    - by meinemitternacht
    I'm running a BIND Master / Slave setup with DNSSEC, but some of my domains use Google Apps for e-mail services. Google doesn't support DNSSEC and BIND doesn't like it at all.

Does anyone here have experience with this?

  • How to configure IIS for SVG and web testing with Visual Studio?

    - by macias
    Let's say I have a simple web page with svg image in it: <img src="foobar.svg" alt="not working" /> If I make this page as static html page and view it directly svg is displayed. If I type the address of this svg -- it is displayed. But when I make this as .aspx page and launch it dynamically from Visual Studio I get alt text. If I type the address of this svg (from localhost, not as a local file) -- browser tries to download it instead of displaying. I already defined mime type in IIS (for entire server -- "image/svg+xml") and restarted IIS. Same effect as before. Question: what should I do more? Update WireShark won't work (it is in documentation), I tried also RawCap, but it cannot trace my connection (odd), luckily Fiddler worked: From client: GET http://127.0.0.1:1731/svg/document_edit.svg HTTP/1.1 Host: 127.0.0.1:1731 User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:10.0.1) Gecko/20100101 Firefox/10.0.1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip, deflate Connection: keep-alive Answer from server: HTTP/1.1 200 OK Server: ASP.NET Development Server/10.0.0.0 Date: Thu, 16 Feb 2012 11:14:38 GMT X-AspNet-Version: 4.0.30319 Cache-Control: private Content-Type: application/octet-stream Content-Length: 87924 Connection: Close <?xml version="1.0" encoding="UTF-8" standalone="no"?> <!-- Created with Inkscape (http://www.inkscape.org/) --> <svg xmlns: *** FIDDLER: RawDisplay truncated at 128 characters.

But the ftp Client stucks allways after processing the credentials and the FTP Server gives you an eventlog "logon error". the error messages indicates that there could be an issue with closed ports. if I turn the ACL to "IP", that means all ports are open, everything is working fine.

  • How do I delete a differential backup?

    - by BlueMonkMN
    I often like to create backups when testing the software I work on, and will sometimes create a differential backup if I want to be able to get back to multiple previous states. However, sometimes I realize that I forgot one thing I wanted to include in a differential backup, or I no longer need a previous differential backup. Sometimes I simply want to create a new scenario from the original base image and start working with a new series of differential backups. So I'd like to be able to delete some older differential backups so I don't get confused about which ones I'm using. But I can't find any way to delete just the differential backups, selectively or all at once.

  • NIC light is turned off after boot on Redhat 4.6 server

    - by hoffmandirt
    I have a 2950 blade server setup with Red Hat 4.6 installed. I cannot get the NIC to work properly after reinstalling Linux. I activated the NIC, but the NIC light will not turn on when I plug the network cable into the hub. The status light on the hub will not turn on either. If I run ifconfig, the NIC status is UP. Also I can ping the IP address that I assign to the Linux machine, but I can't ping anything else that is plugged into the hub. When I reboot the system, the NIC light will stay on until the system fully boots and then it will turn off again. Is there something else that I need to do to get the NIC working? It appears to be disabled even though ifconfig says that it is UP. Maybe I need to configure something within the blade server (iDRAC)?

  • Assistance on setup to Connect an offsite server to the LAN via RRAS VPN - Server 2008 R2

    - by Paul D'Ambra
    I have an office LAN protected using a Zyxel Zywall USG 300. I've set up an L2TP/ipsec VPN on that which accepts connections using a shared secret and I've tested this from multiple clients. I have a server offsite and want to set up RRAS to use a persistent connection to the VPN so that it can carry out network jobs even with no one logged in (I'm using it for Micorosft DPM secondary backup). If I create a vpn as if I were setting up a users laptop it can dial in no problem but if I set up a demand dial interface in RRAS it errors. I enable RRAS ticking only demand dial interface (branch office routing) Select network interfaces, right click and choose new demand dial interface Name the VPN ToCompany Select connect using VPN And then L2TP as the vpn type enter the IP address (double-checked for typos!) select Route IP packets on this interface specify static route to remote network as 10.0.0.0/24 with metric of 1 add dial out credentials (again double checked for typos and confirmed with other vpn connections click finish now I right-click on the new interface and choose properties and then the security tab I change Data encryption to optional select only PAP for Authentication (both as per manufacturer of Zywall) click advanced settings against type of vpn and set shared secret then I select the new interface, right-click and choose connect this dials and then errors with either 720 or 811 as the error codes. However, if I create a VPN by going to Network & Sharing center and setting up as if I was creating a VPN from my laptop to the office (say) it dials successfully so I know the VPN settings are correct and the machine can connect to the VPN. Suggests very strongly the problem is how I'm setting up RRAS. Can anyone help?

  • Silent and scripted install of CPAN and Perl modules?

    - by Mikael Grönfelt
    I need to install CPAN and some Perl modules automatically in a Scientific Linux (RHEL) installation script. Unfortunately the specific modules I want (at least one of them) cannot be found as RPM:s as far as I've seen. So I need to install CPAN, configure it automatically (or with a config file) and then install the wanted modules (including dependencies) automatically as well. This doesn't seem like a very unusual requirement, but I haven't seen any really good documentation on this. The problem is that whenever CPAN is launched for the first time an interactive configuration runs. Can this be skipped somehow? And how do I launch module installations directly from the command line?

  • SSD seems dead after wakeup from Windows Sleep, BIOS stalls but doesn't find it anymore

    - by Abel
    The morning, the following scary scenario happened: I woke up my Windows system Typed in my username and got an error (something like "could not load security xxx", but unsure of exact wording) System auto-restarted after cliking OK It didn't boot up anymore to the SSD with Windows 7 OS (I have another disk I can boot to, but that doesn't see the disk either). Obviously, this happened right after I instantiated a backup procedure, which hasn't succeeded either. The BIOS can't find the drive when I connect to SATA. And it can't find the drive when I connect it to SAS. I have a Dell Workstation T7400, most recent BIOS (version A06), version of SAS Host Bus Adapter BIOS (HBA) is MPTBIOS 6.14.10.00 (2007.09.29) from LSI Logic Corp. Other findings: When connecting to SATA, the DELL Logo screen stays really long (5 minutes) and then at the end of POST it says that a drive is not found When connecting to SAS, the SAS HBA initializing phase takes long (2 minutes, against normally 15 seconds) When running Dell Diagnostics, it doesn't finish and gives the error Exception occurred in module MPCACHE.MDM file "IOAPICSP.ASM" line 1645. I contacted Dell. On their advice I tried different slots and different cables to no avail. I use an APIC battery power, spikes in the power are thus unlikely. My conclusion so far: the disk is dead. I need this disk very badly because it contains the last few days of important development of which not all code was checked in the moment this happened. Are there any ways to recover dead SSD drives? The drive is a new X25-M G2 160GB model SSDSA2M160G2GC 2.5" in an extension bay and has been running without issues for 3 months on SAS.

  • Error setting up Data Protection Manager 2010 Agents / Network "Unauthenticated" in network settings

    - by Bowsa
    I'm not sure if the two are connected but i suspect they are. Basically I'm tring to setup Data Protection Manager 2010 on a fresh install of Server 2008 R2 in a SBS 2003 domain. Everything went fine until trying to install agents across the network. Upon clicking add, i get the following error message: Unable to connect to the Active Directory Domain Services Database. Make sure that the DPM server is a member of a domain and that the controller is running. Also verify that there is network connectivity between the DPM server and the domain controller. ID: 7 As usual (worryingly) the MSDN support for 2010 products is nearly non existant, clicking the error ID simply gives a page not found error. So after 2 days of Googling and trying various fixes (DNS settings, adding permissions to AD objects, rejoining the domain and many more) I thought I'd ask here in the hope that someone out there may have had this issue before. Any help greatly appreciated! Some further info: Firewalls are disabled on the Server 2008, SBS, and client machines. Manually installing and adding the client in also fails, as the DPM server tries to contact the DC first. Edit: I tried creating a new protection group instead, and it gives a different error upon adding the machines: Following machines are not found in AD: COMPUTERNAME.COMPANYNAME.LOCAL Is there a certain directory structure it follows in AD?

  • Is it possible to choose the Amazon Glacier Vault when backing up from Synology NAS?

    - by Jorrit Reedijk
    I am using Amazon Glacier Backup on a Synology NAS (rackstation). But the Synology backup software for glacier does not allow me to choose the vault to backup to. This means I can not give my own name to the vault, but also I can not backup to a previously created vault (I also have this problem now after replacing a Synology rackstation). Is there any way to choose to which vault you want your Synology to backup to? Edit: I have now posted this question to the Synology forum also: http://forum.synology.com/enu/viewtopic.php?f=174&t=86557&e=0 If I can solve the problem I'll post the solutions here also.

  • ESXi boot time with 9 iSCSI targets

    - by Myles Gray
    Our ESXi hosts have always been slow booting when it came to iscsi_vmk loaded successfully - sitting here for almost 5 minutes. In all a full server reboot takes almost 12 minutes. We have 9 iSCSI targets per host (5 SANs with redundant interfaces) configured as dynamic discovery targets. Has anyone experienced this? Can it be remedied with static discovery mode? Are there any debug steps we can work through to help diagnose this? (All our targets are accessible at boot so i'm assuming the host isn't stuck retrying to connect to a target)

  • What does this error mean in my IIS7 Failed Request Tracing report?

    Hi folks, when I attempt to goto any page in my web application (i'm migrating the code from an asp.net web site to web application, and now testing it) .. i keep getting some not authenticated error(s) . So, i've turned on FREB and this is what it says... I'm not sure what that means?

  • Commercial version of Freenet6

    - by grnbeagle
    I've been using Freenet6 from gogoNET to make my mobile device publicly accessible via IPv6. It works quite well except that the service is not as stable because it's non-commercial usage only as their servers are hosted for free by different operators around the world. Apparently gogoNET sells hardware called gogoSERVER which allows one to build a service similar to Freenet6. I've inquired their sales team, but they were unable to tell me which companies have a commercial, production-quality implementation of Freenet6. Specifically I'm looking for the following features in IPv6 service provider: Client-based IPv6 connectivity for mobile devices: gogoCLIENT (gw6c) is ideal for mobile devices since it allows a device to go online regardless of the device's location. API for account maintenance: so that we can create device accounts from our software Static IPv6 address: (or maybe I mean IPv4 address) by this I mean, just like gogoNET6 service (username.broker.freenet6.net), we want to provide our users with a permanent URL for their device Any info on commercial IPv6 service provider utilizing gogoSERVER is appreciated. Thanks.

  • how to portforward port 7300 from server A to server B

    - by Patrick van Hout
    hi, We are using Stunnel. But want to replace it is with an iptables entry if possible. 192.168.123.122:7300 need to be forwarded to 192.168.123.188:7300. So in iptables I set these two entries: [root@dev ~]# iptables -t nat -A PREROUTING -p tcp --dport 7300 -j DNAT --to-destination 192.168.123.188:7300 [root@dev ~]# iptables -A FORWARD -m state -p tcp -d 192.168.123.188 --dport 7300 --state NEW,ESTABLISHED,RELATED -j ACCEPT But it isn't working. I did check that /proc/sys/net/ipv4/conf/eth0/forwarding has the value "1" inside. Any tips or hints? thanks, Patrick
