  • SMTP Unreachable from Specific Networks

    - by Jason George
    I host my business site through a VPS account. The instance runs Ubuntu and I'm using POSTFIX+Dovecot as my mail server. For the most part, the mail server works fine. I have noticed, however, that I can not send mail from specific local networks. I noticed this at a client's office serval months ago. I can receive email, but any time I tried to send mail when connected to their network the connection would time out. Since I could send my mail after leaving, I chalked it up to improper network configuration and didn't worry about it. Unfortunately I've recently moved, switched service providers, and am forced to use the service providers router due to the special set-up they put in place to give me DSL in the sticks--well beyond the typical range for a DSL run. Now I'm unable to send email from home, which is a problem. I have tried sending email through my phone (using cellular service rather than my DSL) just to confirm the server is currently working. I'm not even sure where start debugging. Any ideas on how I might track down the issue would be greatly appreciated.

  • .htaccess to deny access to most xml files

    - by CEich
    I recently had a Joomla site hacked, so I'm trying to harden the site a bit. There's a section in the recommended .htaccess that restricts outside access to the xml files that come with extensions. However, it also keeps my sitemap.xml file from being accessed. How do I allow a certain file whiles keeping the rest? here's the default code: <Files ~ "\.xml$"> Order allow,deny Deny from all Satisfy all </Files> and my modification that caused a 500 error: <Files ~ "(?!sitemap)\.xml$"> Order allow,deny Deny from all Satisfy all </Files>

  • How to direct reverse proxy requests using wildcard vhosts

    - by HonoredMule
    I'm interested in running a reverse proxy with 2-3 virtual machines behind it. Each internal server will run multiple virtual hosts, and rather than manually configuring each individual vhost on the proxy (a variety of vhosts come and go too often for this to be practical), I would like to use something which can employ pattern matching in a sequential order to find the appropriate back-end server. For example: Server 1: *.dev.mysite.com Server 2: *.stage.mysite.com Server 3: *.mysite.com, dev.mysite.com, stage.mysite.com, mysite.com Server 4: * In the above configuration, task.dev.mysite.com would go to Server 1, dev.mysite.com would go to Server 3, yoursite.stage.mysite.com to Server 2, www.mysite.com to Server 3, and yoursite.com to Server 4. I've looked into using Squid, Varnish, and nginx so far. I have my opinions regarding their respective desirability and general suitability, but it's not readily apparent if any of them can handle dynamic server selection in this manner and not require per-vhost configuration. Apache on the other hand can do this handily and simply, but otherwise (aside from being well-known and familiar) seems very poorly suited to the partly-performance-serving task. Performance isn't actually a major concern yet, but it seems foolish to use Apache if another system will perform far better and can also handle the desired 'hands-free' configuration. But so is frequently having to adjust the gateway for all production services and risk network-wide outage...and so also is setting oneself up for longer downtime later if Apache becomes a too-small bottleneck. Which of these (or other) reverse proxies can do it/would do it best? And maybe I should post this as a separate question, but if Apache is the only practical option, how safe/reliable/predictable is apache-mpm-event in apache2.2 (Ubuntu 12.04.1) particularly for a dedicated reverse proxy? As I understand it the Event MPM was declared "safe" as of 2.4 but it's unclear whether reaching stability in 2.4 has any implications for the older (2.2) versions available in official/stable package channels of various distros.

  • Url rewriting stops working after changing default port on iis7

    - by Somesh
    I have migrated the IIS6 webserver 2003 websites to IIS7 webserver 2008 using msdeploy tool. Application pool setting are changed with "Enable 32-bit Applications=true", "Managed_Pipeline_Mode=Classic","Identity=NetworkService" Framework=v1.1/2.0. All the websites are working fine on default port along with url rewriting migrated from iis6. When I start the webserver on port other than default port by changing bindings, url rewriting stops workings and get 404 error in logs. I think I don't have to change the handler mapping cause I am running it in classic mode. How can I troubleshoot this?

  • Can IIS (Ideally Azure) do SSL Proxying?

    - by Acoustic
    My team has been asked to add a new feature to a project we're working on, and none of can find authoritative details on whether it's possible with Windows/IIS. The short of it is that we're hoping to have customers update their DNS with a CNAME record to point their website to our server instead of theirs (they why's are trivial - it's what the app does on behalf of your site). We're using a reverse proxy with several custom modules to serve particular content from the original servers. So far everything works perfectly until we encounter SSL. Is there a way to have IIS serve up an SSL certificate from another server? In other words, is there a way to be a trusted man in the middle? I'm hoping that's possible so that we don't have to require all our clients to re-issue their SSL certs. Frankly, we don't want to have to manage hundreds of certs. I'd also like to avoid a UCC situation if there's a way to because it seems to require re-creating the cert each time a client is added. So, any pointers on proxying/hosting SSL (or even dynamic SSL hosting like http://www.globalsign.com/cloud/) would be appreciated.

  • Network bottleneck/throttling issue

    - by Gavin
    Hi all, It's my first day at a new company and i've been given the task to find out an issue with the internet connection. I noticed that whilst I was downloading a large file, the network grinds to a halt, except for my download. At first I thought it was the internet connection/modem but it seems that whilst the lockdown occurs, I am unable to access any network device. Has anyone experienced this before and if so, do you have any pointers? Looking at the setup. They have an DSL modem that connects to a 10/100 switch. There are only 5-6 computers on the network. Cheers Gavin

  • AXway/tumbleweed EMF in exchange 2007

    - by Buckwheat
    Looking for someone who has implemented an axway EMF recently. I'm about to implement an axway SM product for company wide email encryption. I current have an edge transport server and an exchange 2007 server. I want to route email like the follow: the edge picks up internet email to exchange and all out going email will go out the axway. I have two things to figure out: do I only have to build a new send connector on exchange to point to a smarthost (axway) and disable the send connector going to the transport edge server? and two The axway server has to route notifcations to people. Am I looking into something like this? http://msexchangeteam.com/archive/2006/12/28/432013.aspx

  • Folder Redirection - Explorer requires manual refresh

    - by Pete
    Hello, I am having an issue where - when a users my documents folder is redirected to a DFS share, windows explorer requires a manual refresh after creating a new folder, file, etc. (Interestingly, not when making a new briefcase) I have tried a number of MS knowledge base articles, a hot-fix and a registry change, all with no success. (( http:// support.microsoft.com/?kbid=823291 ; http:// support.microsoft.com/kb/873392 )) The problem only occurs when going through the my documents icon. If I map a home drive for the user to the exact same location (IE - H:\DFS\user\documents) , open that drive and make new folders, then there is no problem. Mapping my documents to H:\ also resolves the issue, however, as we need folder sync and people logging on off site with cached profiles this is not a workable solution (as H: will not map and there will be no access to their docs.) Has anyone managed to figure a fix for this? Thanks, Pete.

  • Difference between accessing a website using Local host and IP address

    - by Cdeez
    I have developed an ASP.NET website and deployed into my IIS server. Now to see that my IIS is installed fine, I type local host in my address bar, and I get the welcome screen of IIS and its documentation in a separate window. Now I gave the url of my website http://localhost/mysites/site2/Default.aspx I access my site. Also giving my IP address instead of local host like: http://192.168.1.46/mysites/site2/Default.aspx also works. Just out of curiosity I wanted to see what happens when I give my IP address in addressbar. It asks me a user name and password saying:The server 192.168.1.46:80 requires a user name and password. I donot know what user name and password it is asking, and as of my knowledge I thought localhost points to my own IP address internally. But what is the difference and also what username and password do I need for it? Update: On chrome and IE just giving localhost displays the welcome screen, but on mozilla, localhost is also asking for a username and password.

  • Is Internet routing (BGP) fully automated?

    - by Adal
    If all the routing tables on the Internet would be erased simultaneously, will the routers be able to rediscover them automatically? I'm having an argument with a colleague who says that the RIPE routing tables are essential, but I remember reading that if the tables disappeared, the BGP protocol will allow routers to rediscover working routes between nodes by querying their neighbors which in turn will query their neighbors until a working route will be detected. Then that route will be used to repopulate the routing tables. After a while, all the routes will be restored (not necessarily the optimal routes). Is that correct?

  • Changing MX records in named zone file

    - by Paul England
    I forgot how all this works. I have a GoDaddy account, using my own DNS and whatnot. I'm having trouble getting my email to work. They said I need to update my MX records. basically, I have the following. 184.168.30.42 is the domain's IP address, obviously. gamengai.com. 14400 IN NS n1 gamengai.com. 14400 IN NS n2 ns1 14400 IN A 184.168.30.42 ns2 14400 IN A 184.168.30.42 gamengai.com. 14400 IN A 184.168.30.42 localhost 14400 IN A 127.0.0.1 ftp 14400 IN A 184.168.30.42 www 14400 IN A 184.168.30.42 mail 14400 IN A 184.168.30.42 subdomain 14400 IN A 184.168.30.42 gamengai.com 14400 IN MX 10 mail Mail doesn't work though... they say to make the following change: 0 smtp.secureserver.net 10 mailstore1.secureserver.net So should the last line point to mailstore1.secureserver.net instead of mail in the last field? What about the other line? I had this working at one time, but it's totally gotten away from me. It's a virtual dedicated server and their support for this stuff is pretty bad... almost as bad as my admin skills since I went the programmer route.

  • Nginx & Passenger - failed (11: Resource temporarily unavailable) while connecting to upstream

    - by Toby Hede
    I have an Nginx and Passenger setup that is proving problematic. At relatively low loads the server seems to get backed up and start churning results like this into the error.log: connect() to unix:/passenger_helper_server failed (11: Resource temporarily unavailable) while connecting to upstream My passenger setup is: passenger_min_instances 2; passenger_pool_idle_time 1200; passenger_max_pool_size 20; I have done some digging, and it looks like the CPU gets pegged. Memory usage seems fine passenger_memory_stats shows at most about 700MB being used, but CPU approaches 100%. is this enough to cause this type of error? Should i bring the pool size down? Are there other configuration settings I should be looking at? Any help appreciated Other pertinent information: Amazon EC2 Small Instance Ubuntu 10.10 Nginx (latest stable) Passenger (latest stable) Rails 3.0.4

  • mod evasive not working properly on ubuntu 10.04

    - by Joe Hopfgartner
    I have an ubuntu 10.04 server where I installed mod_evasive using apt-get install libapache2-mod-evasive I already tried several configurations, the result stays the same. The blocking does work, but randomly. I tried with low limis and long blocking periods as well as short limits. The behaviour I expect is that I can request websites until either page or site limit is reached per given interval. After that I expect to be blocked until I did not make another request for as long as the block period. However the behaviour is that I can request sites and after a while I get random 403 blocks, which increase and decrase in percentage, however they are very scattered. This is an output of siege, so you get an idea: HTTP/1.1 200 0.09 secs: 75 bytes ==> /robots.txt HTTP/1.1 403 0.08 secs: 242 bytes ==> /robots.txt HTTP/1.1 200 0.08 secs: 75 bytes ==> /robots.txt HTTP/1.1 403 0.08 secs: 242 bytes ==> /robots.txt HTTP/1.1 200 0.11 secs: 75 bytes ==> /robots.txt HTTP/1.1 403 0.08 secs: 242 bytes ==> /robots.txt HTTP/1.1 200 0.08 secs: 75 bytes ==> /robots.txt HTTP/1.1 403 0.09 secs: 242 bytes ==> /robots.txt HTTP/1.1 200 0.08 secs: 75 bytes ==> /robots.txt HTTP/1.1 200 0.09 secs: 75 bytes ==> /robots.txt HTTP/1.1 200 0.08 secs: 75 bytes ==> /robots.txt HTTP/1.1 200 0.09 secs: 75 bytes ==> /robots.txt HTTP/1.1 403 0.08 secs: 242 bytes ==> /robots.txt HTTP/1.1 200 0.08 secs: 75 bytes ==> /robots.txt HTTP/1.1 403 0.08 secs: 242 bytes ==> /robots.txt HTTP/1.1 200 0.10 secs: 75 bytes ==> /robots.txt HTTP/1.1 403 0.08 secs: 242 bytes ==> /robots.txt HTTP/1.1 200 0.08 secs: 75 bytes ==> /robots.txt HTTP/1.1 403 0.09 secs: 242 bytes ==> /robots.txt HTTP/1.1 200 0.10 secs: 75 bytes ==> /robots.txt HTTP/1.1 403 0.09 secs: 242 bytes ==> /robots.txt HTTP/1.1 200 0.09 secs: 75 bytes ==> /robots.txt HTTP/1.1 200 0.08 secs: 75 bytes ==> /robots.txt HTTP/1.1 200 0.09 secs: 75 bytes ==> /robots.txt HTTP/1.1 200 0.08 secs: 75 bytes ==> /robots.txt HTTP/1.1 200 0.10 secs: 75 bytes ==> /robots.txt HTTP/1.1 200 0.08 secs: 75 bytes ==> /robots.txt The exac limits in place during this test run were: DOSHashTableSize 3097 DOSPageCount 10 DOSSiteCount 100 DOSPageInterval 10 DOSSiteInterval 10 DOSBlockingPeriod 120 DOSLogDir /var/log/mod_evasive DOSEmailNotify ***@gmail.com DOSWhitelist 127.0.0.1 So I would expect to be blocked at least 120 seconds after being blocked once. Any ideas aobut this? I also tried adding my configuration at different places (vhost, server config, directory context) and with of without ifmodule directive... This doesnt change anything.

  • Dismount USB External Drive using powershell

    - by JC
    Hello, I am attempting to dismount an external USB drive using powershell and I cannot successfuly do this. The following script is what I use: #get the Win32Volume object representing the volume I wish to eject $drive = Get-WmiObject Win32_Volume -filter "DriveLetter = 'F:'" #call dismount on that object there by ejecting drive $drive.Dismount($Force , $Permanent) I then check my computer to check if drive is unmounted but it is now. The boolean parameters $force and $permanent have been tried with different permutations to no avail. The exit code returned by the dismount command changes when the params are toggled. (0,0) = exit code 0 (0,1) = exit code 2 (1,0) = exit code 0 (1,1) = exit code 2 The documentation for exit code 2 indicates that there are existing mount points as a reason why it cannot dismount. Although I am trying to dismount the only mount point that exists so I am unsure what this exit code is trying to tell me. Having already trawled the web for people experiencing similar problems I have only found one additional command to try and that is the following: # executed after the .Dismount() command $drive.Put() This additional command does not help. I am running out of things to try, so any assistance anyone can give me would be greatly appreciated, Thanks.

    So I tried creating a new partition on Fedora 17 using fdisk as follows: Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (2048-823215039, default 2048): Using default value 2048 Last cylinder or +size or +sizeM or +sizeK (1-9039, default 9039): +15G Once this was done,instead of formatting the partition I created, I ran the partprobe command to write the changes to the partition table. On rebooting the computer, it drops to the debug shell and gives me the error as follows: dracut warning:unable to process initqueue dracut warning:/dev/disk/by-uuid/vg_mymachine does not exist dropping to debug shell dracut:/# While trying to run fsck on the said partition from the debug shell, it says "etc/fstab not found" and inside /etc I see a fstab.empty file. Is it now possible to retrieve what I have from the computer? Any help would be appreciated. Thanks in advance Edit: I've also tried the following steps for additional troubleshooting: I tried to boot using the Fedora disk and tried the rescue mode - says no Linux partition detected. I tried to create an fstab file by combining the entries from blkid and the /etc/mtab file and using the UUIDs from the mtab file - It didn't work. As soon as I rebooted the machine, it promptly dropped me in to the debug shell and the fstab file which i created wansn't there anymore in /etc (part of this solution)

  • Are there any Microsoft Exchange Clients for iOS and Android that store their local data in an encrypted manner?

    - by Zac B
    I don't feel like this is a product recommendation question, more of a "does this tech even exist and is it feasible" question, but if I'm wrong, feel free to give this question the boot. Context: Our company has a bunch of traveling employees who access the company's Exchange server via thier iDevices or android phones, but because of the data protection laws in the state where our company is based (and the nature of the data our company works with), a recent security audit found that all mobile devices (laptops, phones, etc) operated by our company need to have all company correspondence and related data encrypted all the time. For laptops, that was easy: BitLocker or TrueCrypt, problem solved. For phones and tablets, however, I'm stumped. Sure, you can put lock screens/passwords on the phones, but the data is still accessible via external extraction, as law enforcement authorities already know. Question: Are there any clients for Microsoft Exchange that run on iOS or Android which store local data encrypted? The people using our mobile devices do a lot of their work while offline, so just giving them OWA access with SSL connection security isn't enough. Are there apps/technologies that present an additional login credential prompt to decrypt locally stored data in the app's storage area on the phone? My gut reaction when I started looking into this was "that doesn't sound like something Apple would allow into the App Store", but I've been wrong before...

  • Logging Bounced messages to a Database (Postfix with virtual domains/users)

    - by Gurunandan
    We have a postfix installation with a couple of virtual domains each with virtual users. These domains and users are mapped using a mysql database. I have been until now tracking bounces by parsing the postfix log file. I suspect there must be better and more efficient ways of doing this. I thought of three but I am not sure what is best: Write a Postfix content filter that logs the bounce and throws away the mail Use procmail - but I am not sure how procmail would work with virtual users who have no $HOME defined Write a script that POPs mail from mailboxes; parses and logs them and deletes the bounced email I would appreciate advise on which would be best from a maintenance point of view and efficient from conserving server resources point of view. Thanks
