| What could cause blocked requests in IIS? Posted: 04 Sep 2021 04:12 PM PDT I'm using IIS on Windows Server 2016 with MySQL and PHP on two almost identical servers. I've recently noticed a slowdown on one of my two servers but it happens only when my site tries to execute multiple instances of a script at the same time. They seem to get stuck on each other. A perfect example is my search page. When the user types in a search query, with each keyup (after the second letter) a search is executed as long as there's at least a 200 ms delay since the last keypress. So if you type fast, it only does one search at the end but for slower typers (those who wait more than 200 ms between key presses) this will trigger multiple calls to the search results. See this screenshot. BAD SERVER Notice all the pending requests and in this screenshot the first one just finished at 19.08 seconds. Obviously much too long. By the time they're all done they're all well over 15 seconds to return a simple resultset. BAD SERVER Keep in mind that these queries take just a fraction of a second when run in MySQL Workbench and also when run on my other server which is not suffering from this problem. See in this screenshot (from the good server) the exact same search returns in a quarter of a second. GOOD SERVER It seems to me that (on the bad server) they're not able to execute simultaneously for some reason because if I execute just a single search (by typing quickly enough to trigger only a single search) it comes back quick, but if I execute multiples like this, they all get stuck like in a traffic jam. What could cause this? This next screenshot shows the result if I trigger only a single search on the bad server. As you can see it comes back super fast. So the problem is only when executing multiples of the same script simultaneously. BAD SERVER I did make some changes to the bad server recently but as far as I can remember, the only changes I made were to allow bigger file uploads.
It's possible that I made other changes to this server that I can't remember. TEMPORARY FIX I can mitigate this problem by allowing a longer delay between key presses when searching, and I've done this, increasing it to 800 ms so even slow typers don't see this problem, but this is only a band aid solution and does not address the underlying issue which also affects other areas of my site. WHAT I'VE TRIED So far I've confirmed that my IIS config, MySQL config (my.ini) and my PHP config (php.ini) are all identical in every way that matters on both servers (at least as far as what seems obvious to me). I've also confirmed that the select statements I'm running in this search perform equally well on both servers if I execute them in MySQL Workbench. It's only in my web app where I'm having this problem. I temporarily undid the two changes I made to IIS for larger file uploads just in case, but that seemed to make no difference. I've also downloaded and installed LeanSentry which is warning me once or twice a day that my site has seen blocked requests, which I assume is exactly what I'm seeing here, but unfortunately LeanSentry can only pinpoint the source of the problem with ASP pages, not PHP. So it essentially only confirms for me that there's a problem but it can't help me beyond that. OTHER SYMPTOMS I see similar problems if I open multiple reports simultaneously. If I allow one report to finish loading before opening the next one they all load quickly, but if I force my app to open multiple reports at once, they all get stuck. What could be causing this issue of bottlenecking?  |
| Address to be used to access private ipaddress for AZURE resource from on-premise Posted: 04 Sep 2021 02:43 PM PDT I can see how we can make an AZURE database, say COSMOS DB, a private IP address with Private link, that is fine. If you want to access that private link / IP address database from on-premise via site2site vpn, with a tool like Spotfire or Tableau, how do we specify the connection string that goes via the ExpressRoute or Site2SiteVPN? I cannot find any examples on that and how that occurs. It must be basic, but I cannot see it. Update Looking at this: https://docs.microsoft.com/en-us/azure/private-link/private-endpoint-dns#on-premises-workloads-using-a-dns-forwarder
I get the impression that the name "azs1l1.database.windows.net" would be the connection string I need?  |

| Does apache open and close every log on every access? Posted: 04 Sep 2021 07:36 PM PDT The question is about the access and error logs, particularly with multiple hosts (apache instances installed on more than one server) and keeping the logs centrally on a network file system. Does apache close each log file after every write? If yes, on a busy server hosting many sites each with it's own log, that would seem to be a potential performance bottleneck? If No, what is the solution when having multiple servers writing to a single logging location on a network file system?  |
| Posted: 04 Sep 2021 02:34 PM PDT Setup: a .NET (4.6) client application connects to a remote SOAP service over HTTPS. The remote service can be configured to require a a client certificate or not. What I am looking as an answer is any possible explanation of why scenario #2 fails ... the following 3 scenarios were all tested using exactly the same code base, only changing the certificates involved and whether or not a client certificate was required by the service. Scenario #1 - no client certificate required
Scenario #2 - client certificate required, certificate A used
Scenario #3 - client certificate required, certificate B used
What we can see from logs is that in both scenario #2 and #3, the client and server negotiate to use TLS 1.2. After running the above multiple times, checking everything, my only conclusion is that certificate A is somehow not compatible with the setup - either the .NET client decides not to present it, or the service cannot accept it. But what could possibly be different/missing?  |
| iRedMail: Domain alias not working with some external mails (diacritics/punycode) Posted: 04 Sep 2021 07:44 PM PDT After successfully setting up an iRedMail server for my main domain, I tried to add my secondary domain as an alias by following the steps on here: https://docs.iredmail.org/sql.add.alias.domain.html This didn't do the trick just yet, so I additionally added the secondary domain into the /etc/postfix/main.cf: Note: I didn't remove any of the existing mysql entries under virtual_alias_maps. And entered the mapping into /etc/postfix/virtual and executed "postmap /etc/postfix/virtual" afterwards: This is working internally on the server. user1@domain1.tld can send to user2@domain2.tld and user2 will receive the mail in his mailbox. External emails also still arrive when sent to user@domain1.tld. Unfortunately it doesn't function with external mails to the secondary domain. In my /var/logs/mail.log I find the following lines: And: On port 12340 dovecot is listening: In my dovecot log I find the following line repeatedly: After some further testing with different external mail hosters, I realized that 2 out of 4 mails arrived when sent to the secondary domain. GMail and Hotmail didn't, my company's exchange and some other web provider came through. And that's where I'm stuck. I suspect one of two things: Either I simply missed a necessary configuration, which seems highly likely, since I've never set up a mail server on Debian before, or the dovecot error is caused by my secondary domain. The secondary domain contains an umlaut (ä/ö/ü), which I'm well aware can cause some issues. Therefore I also own the domain in it's punycode formatted variant. So, whenever I added my secondary domain with it's umlaut to a configuration, I also added the punnycode version of it, assuming it would solve any issues in that regard. iRedMail/postfix/dovecot/whateverelseisinvolved seem to be working fine with punnycode/umlauts per se, it just seems to depend on the sender, since only half the mails go lost (sender won't get an error). Any guess as to why or what logs I could check to dig deeper into this? Did I simply miss to configure something obvious? Any push into the right direction is highly appreciated. Regards, Snot ==== Basic Info ====
==== Edit ==== As far as the base setup; After a clean Debian 10 installation I've followed the steps in this guide https://www.linuxbabe.com/mail-server/debian-10-buster-iredmail-email-server Any specific config that alters from the guide has been mentioned in the post. I've additionally issued a certificate which includes the main domain and the secondary domain in punnycode. Here the various logs on boot: /var/log/mail.log: /var/log/dovecot/dovecot.log: grep postfix /var/log/syslog: I've disabled thequota features and enabled SMTPUTF8 in my postfix main.cf, no notable change except from an additional line on boot in the mail.log: The behaviour is still the same unfortunately. After further analyzing the logs I realized that it seems as if the mails from the providers that come through get sent via punycode (even if I specifically sent it to the domain with the umlaut/non-ASCII-char). GMail on the other hand actually sends the mail to the domain that contains the umlaut (Non-punycode, even if I specifically use the punycode format in the recipient mail adress). So, I'll either need to teach my server to handle the non-ASCII-chars or I need to teach Google to send via punycode. Or teach my server to translate umlauts to punycode. Option 2 is obviously not really on option, so 1 or 3 it is. mail.log entry from non-GMail hoster mail: mail.log entry from GMail mail:  |

| nginx config using variable in ssl_certificate path throws permissions error Posted: 04 Sep 2021 07:02 PM PDT The nginx configuration server block: This is using the variable $ssl_server_name in the certificate directives which is supported since nginx 1.15.9. Relevant part of the nginx docs. The configuration passes nginx -t and loads without issues, but page does not load in browser, and there is a permissions denied error opening the cert in error.log even though nginx is running as root: When I replace $ssl_server_name with the domain name in the nginx configuration then there is no permissions error reading the very same cert file, and the page loads in the browser. Why does using the variable in the cert path not work? UPDATE: I updated the archive folder group to www-data, still seing the permissions error: UPDATE 2: Added group read and execute permissions to archive folder, still seing the permissions error: UPDATE 3: Tried becoming www-data using sudo but got an error: Update 4: I also updated the permissions on the symlinked path live folder, still seing the permissions error: Update 5: Listing the permissions of all dirs in path including symlinks: Update 6: Tried temporarily changing the shell for www-data user, became www-data using sudo and tested reading the cert was possible, but the permission error is still happening: Update 7: Tried exporting the certs to another folder: Then decided to check again as the www-data user because last time I checked it was when the certs were in the letsencrypt folder, also this time I remembered to check both cert and key: Once I addd the group read permission for www-data to the privkey.pem, the browser was able to load the page. :) Thanks to all that commented on this question.  |

If I was to guess, I would say it has something to do with VLAN4 through 7 as there are only four physical lan ports in the router... Does anyone know how to set this up on the Draytek?

| SSL Certificate Not Getting Refreshed Posted: 04 Sep 2021 03:05 PM PDT I am trying to change the SSL Certificate for my website. I got the new certificate issued by Comodo and installed it on my web servers. My servers are running IIS7.0. I also binded the https protocol for my websites to the new certificate. Then I deleted the old certificate(which was expired) from IIS. Then I restarted the website I restarted the IIS Service from an administrator command prompt. I rebooted the servers However, when I try to open my website in a browser, it is still giving me the expired certificate error and showing the information of the older certificate in the certificate info box. Does anyone have an idea what might be going wrong? Does the new SSL certificate take some time propagating across the DNS? (My servers are hosted in AWS Cloud as EC2 instances) Any help or suggestions would be appreciated. Thanks  |
| Redirect from Old Site to New Site on different folder Posted: 04 Sep 2021 05:02 PM PDT I want to redirect all request from a url host www.hostname1.com (including all subdirectores-www.hostname1.com/....) to a different url with a different host, www.newHost.com. I have already made the change in the DNS but am wondering what changes I should make on the server on which www.newHost.com is hosted so that the redirect takes place with the new url displayed on the browser. I have look at the IIS. Under the configurations for www.newHost.com, I can bind www.hostname1.com to the same IP as www.newHost.com but this works only for the home page for www.hostname1.com and does not rewrite the url address in the browser window. Please advise on how to make this change.  |

| IIS 7 and ASP.NET State Service Configuration Posted: 04 Sep 2021 04:08 PM PDT We have 2 web servers load balanced and we wanted to get away from sticky sessions for obvious reasons. Our attempted approach is to use the ASP.NET State service on one of the boxes to store the session state for both. I realize that it's best to have a server dedicated to storing sessions but we don't have the resources for that. I've followed these instructions to no avail. The session still isn't being shared between the two servers. I'm not receiving any errors. I have the same machine key for both servers, and I've set the application ID to a unique value that matches between the two servers. Any suggestions on how I can troubleshoot this issue? Update: I turned on the session state service on my local machine and pointed both servers to the ip address on my local machine and it worked as expected. The session was shared between both servers. This leads me to believe that the problem might be that I'm not using a standalone server as my state service. Perhaps the problem is because I am using the ip address 127.0.0.1 on one server and then using a different ip address on the other server. Unfortunately when I try to use the network ip address as opposed to localhost the connection doesn't seem to work from the host server. Any insight on whether my suspicions are correct would be appreciated.  |

| SBS 2008 Backup Drive Full - Error Code '2147942512' Posted: 04 Sep 2021 02:00 PM PDT We are using Windows Backup on SBS 2008 SP2 and backing up to 1TB external hard drives. Recently after switching drives our backup started failing because the backup drive is full and auto-delete isn't automatically deleting older backups/show copies. I'm trying to get more information to help me effectively prevent this problem from reoccurring in the future. How I can tell that the drive is getting full: One of the most informative posts I've found on this error is located on Microsoft's Technet Forums here. In that post, a Microsoft representative gives this hazy explanation: auto-delete feature to ensure that at least some old backup copies are maintained on the disk -- does not automatically delete backups if space utilization by older copies is less than 1/8 of the disk size or in other words, 13% of the disk size. that means if the one full backup copy does not fit in the 7/8 of the disk size, backup may fail with disk full error. auto-delete will not automatically delete older versions to reclaim more older versions of backup. In the above explanation, I do not understand what is meant by "older copies" except that it appears that anything older than the very last shadow copy would be considered "older copies". I'm going to make the assumption that this problem where auto-delete will not work will affect any hard drive that is large enough to make an effective backup drive, or in other words, any hard drive that is large enough to hold more than one backup/shadow copy at once. The same MS representative proposes the solution of using a larger backup drive. I can't understand how this will help. It appears to me it will simply delay the problem until a later date. In order to resolve this problem for now, I did the following:
However, I do not feel this is a satisfactory solution to prevent the problem from happening again in the future. Does anyone have a solution to prevent your Windows Server backup drive from getting full?  |

| IIS no longer saving session variables Posted: 04 Sep 2021 03:05 PM PDT I'm running IIS v7 on a Win7 development machine. I have PHP code that saves session variables and calls them back later. This has been working on this machine for some time. For some reason now, the session variables dissapear immediatly after saving. Code that used to work fine on http://localhost/, suddenly now does not. I have tested different browsers - the vars dissapear regardless of browser. I have tested identical code on different servers. The problem exists only on this development machine. I tried some code that saves a session var, then reads it back and displays it, then shows a link to click on to read it back and display again. What happens is the session var DOES get written and read back and displayed ok. But when you click the link to view it again, it's gone. I don't recall making any changes to IIS. But I did run several malware scanners and clean-up tools. Is anyone aware of any setting in IIS that disallows session vars? Any other throughts?  |
| Can I bind a (large) block of addresses to an interface? Posted: 04 Sep 2021 04:30 PM PDT I know that the ip tool lets you bind multiple addresses to an interface (eg, http://www.linuxplanet.com/linuxplanet/tutorials/6553/1/). Right now, though, I'm trying to build something on top of IPv6, and it would be really useful to have an entire block of addresses (say, a /64) available, so that programs could pick any address from the range and bind to that. Needless to say, attaching every IP from this range to an interface would take a while. Does Linux support binding a whole block of addresses to an interface?  |
| Cross domain javascript form filling, reverse proxy Posted: 04 Sep 2021 10:04 PM PDT I need a javascript form filler that can bypass the 'same origin policy' most modern browsers implement. I made a script that opens the desired website/form in a new browser. With the handler, returned by the window.open method, I want to retrieve the inputs with theWindowHandler.document.getElementById('inputx') and fill them (access denied). Is it possible to solve this problem by using Isapi Rewrite (official site) in IIS 6 acting like a reverse proxy? If so, how would I configure the reverse proxy? This is how far I got: The rewrite works, http://ourcompany.com/ourapplication/CarChecker, as evident in the logging. From within our companysite I can run the carchecker as if it was in our own domain. Except, the 'same origin policy' is still in force. Regards, Michel  |
