  • Cannot 301 redirect with IIS URL Rewrite Module

    - by Justin
    I am trying to troubleshoot my issue with the URL Rewrite Module on IIS 7. I migrated a Wordpress blog over to BlogEngine.net. There were only about 5 entries that I wanted to use 301 redirects to the new blog, so I wanted to simply create 5 exact match redirect rules using the rewrite module. For some reason the exact match rule never seems to take effect, I always get a 404 error when the original url is navigated to. I verified that my exact match pattern matched the existing backlinks and it does. I then tried a simple test and got the same behavior, no redirection. I created a page, test.html, on my site, I then created a second page, test2.html. So my exact match pattern is: "http://www.mydomain.com/test.html" And the rule is supposed to do a 301 redirect to "http://www.mydomain.com/test2.html " The redirect never happens. I created the steps for the rule based on the instructions in this page: http://learn.iis.net/page.aspx/461/creating-rewrite-rules-for-the-url-rewrite-module/ I don't see that I left out a step. After I apply the rule I've even gone as far as doing an IISReset to make sure it would be in effect but still no luck. Any thoughts on what I might have left out? (Note: my rewrite rules dont include the " " around them but I had to add since serverfault thinks I am trying to spam the system with multiple urls.)

  • Vista gets stuck in an endless loop while booting

    - by Mason Wheeler
    I put my laptop to sleep last night, and when I woke up this morning... it didn't. So I tried to reboot, and everything went fine until it got to the Vista splash screen, where it's supposed to display the logon. Here, it hits an endless loop: Display the cursor with the blue spinny thing that replaced the hourglass, for 5-10 seconds Display "Please wait..." for about half a second Screen flashes to black, then quickly back to the Vista splash screen Goto step 1 The whole time, my hard LED is on almost non-stop. I can boot into Safe Mode... sometimes. Sometimes it'll load all the drivers, then sit there for about 10 minutes, spinning the hard drive non-stop, then reboot with no warning. I tried booting to Last Known Good Configuration. Didn't fix anything. When I've managed to get into Safe Mode, I tried running CHKDSK. Didn't fix anything. I tried running System Restore to each of my last two restore points. Didn't fix anything either time. I ran a virus scan. Didn't find anything. I tried calling the manufacturer (Alienware), only to discover that my warranty expired last freaking week and now I can't get it fixed without paying exorbitant sums of money. I'm about at my wits' end here. Has anyone seen this problem before? Does anyone know how to fix it? Does anyone know a solution that does not involve reinstalling the OS and losing an entire year's worth of program installations, Windows Updates and configuring and tweaking things until it's working just like I want it to?

  • Firefox is very slow when establish SSL sessions

    - by yanglei
    Using wireshark, I discovered that Firefox v3.0 gets stuck every time before "client key exchange, change cipher spec" stage when establishing a SSL session. Specifically, it takes 0.8~1.8 second before Firefox send "Client Key Exchange" request. This is unacceptable since our application is HTTPS only. I tested this on IE6 and IE8, both works well. Any clues? [Update] Finally, I found the reason of 1 ~ 2 seconds stuck by displaying all captured packets in Wireshark. After the "server hello" stage, Firefox makes a request to ocsp.verisign.com combined with an additional DNS lookup for that domain. Firefox must wait the revocation status from OCSP before entering the next stage of SSL. Depends on whether DNS cache is in effect, this process takes 1 ~ 2 seconds. A interesting observation is that the IP packet contains "client key exchange" has a high possibility to get lost and thus a TCP retransmission is necessary. When this happens, the process can take 3 seconds at worst. I'm not sure if this is a coincidence or a bug. Anyway, here is the result from Wireshark: (delta-time) 0.369296 src-ip dst-ip TCP [ACK] Seq=161 Ack=2741 Win=65340 Len=0 2.538835 src-ip dst-ip TLSv1 Client Key Exchange, Change Cipher Spec, Finished 2.987034 src-ip dst-ip TLSv1 [TCP Retransmission] Client Key Exchange, Change Cipher Spec, Finished The difference between Firefox and IE is this: Firefox 3 enables OCSP checking by default where as IE only supports it. So, there is no problem with both IE6 and IE8. This is indeed a "certificate revoke" problem. Thanks

  • PowerPoint save group as picture creates asymmetric edge, how to fix?

    - by Se Norm
    I created tons of figures for my thesis in PowerPoint and now I realized that when I try to save the grouped items (= one figure) as a picture (EMF), it somehow asymmetrically adds a border on the left and the bottom. First one is original group, second is the same pasted as a picture. Original group: Pasted as a picture: Does anyone have an idea how to fix that for a huge number of figures? I think it only started happening when I used a page size of 1m x 1m in PowerPoint to be able to zoom in more for some figures. However, I cannot not simply change the page size now as it messes up font and object sizes. Also, copying it into a smaller page and then saving as EMF doesn't do the trick. Maybe it is not related to the page size after all. Cropping every figure individually would be a lot of work, so I hope there is a different solution. I found the origin of the problem: the text label in the left bottom corner of each image (0s, 8s, 16s). I still do not understand why it is happening though, since the text label does not expand over the edge of the image (it was aligned using the align left function). It would still be great if there was an easy way to fix this, especially as I want to keep the text where it is.

  • Very strange networking problem in all computers in my house

    - by Anthony
    I have three computers in my house: One desktop (wired), and two laptops (wireless). I'm using Cox Communications (yes they suck), and yesterday they had a major outage. I know it was them because I called them up when I started losing connection to the internet. All the computers can connect just fine, but they don't have internet access. It just says "local only". The weird thing is, some of them work occasionally. For the first day my laptop was working perfectly, while all the other computers couldn't connect. Later on in the day it got reversed, and the desktop was the one with internet access. By the second day the problem on Cox's end was fixed, but we still had no access. I called them up and they reset my modem, and did the usual troubleshooting stuff. It never fixed the problem, but we found out that the problem had to do with conflicting IP addresses. My router was a Linksys WRT54G and it was about 5 years old. I figured it might have gotten damaged from the outage since it was so old, and now it's having trouble "fixing itself" and giving out the proper IP addresses. So I bought a new router, a Cisco Linksys E1000. I set everything up, and still the same problem. My computer has access right now (that's how I'm writing this), but no other computers seem to be able to get access. Is there possible damage to the modem? Can someone help me please? Sorry for this being so long.

  • APACHE - PHP - Bounce emails

    - by user1179459
    I want to improve our mail server lists by handling all the bounces we get in our websites. I have a website which has over 8000+ users and another website which as over 1500+ users, they are emailed various notifications every second, ie. job alerts, email alerts, I am using POP connections with EXIM on APACHE server, most scripts are based on PHP language generates email on the fly. Problems i have But some users has registered long time ago and now quite few has bounce email address Some users register with dummy emails like [email protected] which never existed but a valid email address, any chance of stopping this without asking them login to the email account and clicking links which dont work most times.. (too annoying to the end user) Server is sending unnecessary emails can be avoided if i know they dont exists ? Solutions i need to have Is there a way i can download the bounce email list somewhere (WHM/Cpanel), i know exim mail has it but its not readable (i need a file like CSV or something similar to scan them over and write a php script to delete the users from the database ?) I need to know if there is any function in the PHP that can check the existence of the email address on the fly ? so that i can set the email send function in the mailer class to check before it sends out. On the server will bouncing emails are going to eatup lots of server resources ? like memory/cpu on processing them ? or are they are minimal where we dont have to worry about this at all ? May be a opensoruce or linux software to capture them and view them in a report basis and cleaning them up ? I am not a linux expert or server admin but i do lot of PHP coding, so please be descriptive of the solutions specially if they are linux commands Thank you!

  • Why am I seeing MailSlot Browse messages on unrouted ports of my Linux box?

    - by nmichaels
    I have a Linux box (Debian squeeze) with several NICs. The ones of interest are: eth3 - my main link to the network (dhcp on 10.20.30.0/24) eth0 - the first connection to my test network (static: 192.168.1.2) eth4 - the second connection to my test network (static: 192.168.1.1) My routing table looks like this: $ sudo route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.20.30.0 * 255.255.255.0 U 0 0 0 eth3 default 10.20.30.254 0.0.0.0 UG 0 0 0 eth3 I have the 2 test net ports connected to each other with a crossover cable and an instance of wireshark running on each port. Every once in a while, I'll see a packet like the following show up. Who could be doing this, and how do I convince them to stop? I do have Samba running on the machine (for a cifs mount) but don't see why it would be sending packets out to unrouted ports. I had a Windows VM running in VMWare Client and thought that might be causing it, but it still happens without it. What I want is totally silent interfaces so I can run some tests with Scapy over them.

  • Apache2/mod_fcgid/PHP Process Limits Not Respected

    - by Daniel
    I've recently moved to Apache2 / mod_fcgid / PHP from nginx / php_fpm. This is the second server on which I've made this migration, but it's used much less frequently than the first, which is working like a charm. The problem is in the PHP processes that it's spawning. In looking at the mod_fcgid documentation, it appears that the default for killing idle processes is 300 seconds; I've changed that to 20. At this point, I'd be fine if 300 would work - but it's not happening. It's been running for nearly a day now, and server-status shows 12 active processes: Process name: php5 Pid Active Idle Accesses State 19243 84879 14420 11 Ready Process name: php5 Pid Active Idle Accesses State 20954 82143 149 22 Ready 20947 82149 149 22 Ready 20953 82143 149 13 Ready Process name: php5 Pid Active Idle Accesses State 20589 82765 23644 72 Ready Process name: php5 Pid Active Idle Accesses State 17663 86103 2034 117 Ready Process name: php5 Pid Active Idle Accesses State 19862 83961 1976 91 Ready Process name: php5 Pid Active Idle Accesses State 18495 85825 5164 18 Ready Process name: php5 Pid Active Idle Accesses State 25463 75109 23948 24 Ready Process name: php5 Pid Active Idle Accesses State 2466 60019 60016 2 Ready Process name: php5 Pid Active Idle Accesses State 20729 82541 12592 23 Ready Process name: php5 Pid Active Idle Accesses State 22135 80616 46361 6 Ready PHP applications are not being served at this point - Apache is returning a 503. However, it is still serving the server-status module, and mod_mono/Mono 2.10 applications are still being served. The problem is with the PHP. /etc/apache2/mods-available/fcgid.conf... <IfModule mod_fcgid.c> AddHandler fcgid-script .fcgi FcgidConnectTimeout 10 FcgidMaxRequestsPerProcess 500 FcgidIdleTimeout 20 FcgidFixPathinfo 1 FcgidMaxProcesses 10 </IfModule> (heh - Max Processes isn't being respected either...) Of course, fcgid.conf is smylinked in mods-enabled.

  • 2nd instance of mysql closes/doesnt start no warnings/errors?

    - by acidzombie24
    I have an external HD and i'd like to run a 2nd mysql instance on it. I used the windows installer to install/configure mysqld as a service on windows7. I took the my.ini from C:\Program Files\MySQL\MySQL Server 5.5\my.ini Then edited the port (client and mysqld), datadir and innodb_data_home_dir. After running this command "C:\Program Files\MySQL\MySQL Server 5.5\bin\mysqld" --defaults-file="f:/dev/my.ini" I found an error which was all about the innodb_data_home_dir directory not existing. After that I ran the command again. Mysqld simply starts up for a second then immediately closes. I see no message in my command prompt. I know this command line args are correct as i see the mysqld service using the same one except a different my.ini path. Also it did tell me about the directory not existing so i know it is reading the new ini file. How do i figure out why this 2nd instance of mysqld is closing? How do i get 2 instance running? I'm using v 5.5

  • SVNParentPath directory authorization

    - by James
    The question is a bit stupid but I can't get it sorted. I have a server with SVN that uses the SVNPath directive in httpd.conf and all works fine with path authorizations. Now I'm installing a second serer where I'm going to use SVNParentPath directive and I've got it all running except I can't get the authorization part quite right. From what I understand it's the same as when you use SVNPath but you need to specificy the repo name before the folder name.. My SVNParentPath is /srv/svn/ and I created a directory /srv/svn/testproj and then ran svnadmin create /srv/svn/testproj Now i'm configuring my authorization file: [/] * = svnadmin = rw adusgi = rw [testproj:/svn/testproj] demada = rw degari = rw scarja = rw Now if I try to commit /svn/testproj using user svnadmin or adusgi all is fine. If I try for example demada it doesn't work... (I've run the htpasswd2 commands for the user obviously. The directory is correct or atleast thats how I use the directory with the SVNPath server thats already running, the part I think I'm getting wrong is the repo name, I just used the directory name but what am I really supposed to put there?? Thank you, James

  • Windows errors, how do I find root cause and fix it? Getting several errors

    - by Eric Martin
    My server is having issues and not responding to customer's https requests. I checked the event viewer and found several errors. These two are listed a couple of times: WINS encountered a database error. This may or may not be a serious error. WINS will try to recover from it. You can check the database error events under 'Application Log' category of the Event Viewer for the Exchange Component, ESENT, source to find out more details about database errors. If you continue to see a large number of these errors consistently over time (a span of few hours), you may want to restore the WINS database from a backup. The error number is in the second DWORD of the data section. And this one: An error occured while using SSL configuration for socket address 0.0.0.0:444. The error status code is contained within the returned data. SQL Server is not ready to accept new client connections. Wait a few minutes before trying again. If you have access to the error log, look for the informational message that indicates that SQL Server is ready before trying to connect again. [CLIENT: xxx.xxx.xxxx.xxx] I also found this in the event viewer but the computer has been restarted since this message and I have not seen it again. Configuring the Page file for crash dump failed. Make sure there is a page file on the boot partition and that is large enough to contain all physical memory. This is my virtual memory settings: I'm not familiar with WINS so I wasn't sure if that is where I start or how to resolve it. Is the WINS error causing the other problems or should I be looking somewhere else?

  • I am under DDoS. What can I do?

    - by Falcon Momot
    This is a Canonical Question about DoS and DDoS mitigation. I found a massive traffic spike on a website that I host today; I am getting thousands of connections a second and I see I'm using all 100Mbps of my available bandwidth. Nobody can access my site because all the requests time out, and I can't even log into the server because SSH times out too! This has happened a couple times before, and each time it's lasted a couple hours and gone away on its own. Occasionally, my website has another distinct but related problem: my server's load average (which is usually around .25) rockets up to 20 or more and nobody can access my site just the same as the other case. It also goes away after a few hours. Restarting my server doesn't help; what can I do to make my site accessible again, and what is happening? Relatedly, I found once that for a day or two, every time I started my service, it got a connection from a particular IP address and then crashed. As soon as I started it up again, this happened again and it crashed again. How is that similar, and what can I do about it?

  • Password-protected sharing allows access to users who have no account?

    - by romkyns
    Running Win7 on two computers in my LAN. Computer A has password-protected sharing enabled, and shares a folder. It has a single user account "Bob", and the Guest account is turned off. The network is workgroup-based. According to the descriptions of the "password-protected sharing" I could find, the only people who can access the shared folder via the LAN are those who know the username+password for the "Bob" account. However a second computer on the LAN is able to view this shared folder by simply browsing to Computer A. They don't need to enter any passwords or anything. The only user account registered on that PC is called "Jim", and has a different password from "Bob". How on earth is computer B able to view this shared folder? Is the popular description of the "password-protected sharing" feature inaccurate / did I misunderstand it big time? P.S. There is a possibility that the password for "Bob" has been entered on that PC once, and possibly the "remember password" box was checked. I've looked in the "Credential Manager" on both computers and there is nothing saved anywhere.

  • Apache / PHP Begins to Deny SQL Requests after about 2000

    - by Daniel Stern
    We have a web page on our server that we use to run administrative scripts. For example, we might run the script "unenrolStudents()" which runs 5,000 SQL SET commands one after another and sets 5000 student entries in an SQL database to unenrolled. However, we are finding that after running a few thousand queries (it is not totally consistent) we will be "locked out" by our server. SYMPTOMS OF LOCKING OUT: - unable to connect to server with winSCP - opening putty with that connection shows a blank screen (no login / pass) - clearing cookies / cache in chrome does NOT fix locking out - other computers in the office ALSO become locked out - locking out can be triggered with a high frequency of requests (10000 in 1 second) or by less over time (10000 in 500 seconds - this will still cause a lockout even though the frequency is much less) We believe this is a security feature of our own Apache. I know we are using Suhosin but I didn't configure it so I don't know. How can I disable this locking effect so that I can confidently run all my SQL requests and they will go through? Has anyone else dealt with this and found workarounds? Thanks DS

  • sysctl.conf not running on boot

    - by Brian
    At what point is sysctl.conf supposed to be read during boot, and why might it not be running? I have the following settings which are not being applied when I reboot: net.bridge.bridge-nf-call-arptables = 0 net.bridge.bridge-nf-call-ip6tables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-filter-pppoe-tagged = 0 net.bridge.bridge-nf-filter-vlan-tagged = 0 fs.nfs.nlm_udpport = 32768 fs.nfs.nlm_tcpport = 32768 The first section is needed for KVM bridging, and the second is to run the NFS lock manager on a known port. However, after booting, these values have not taken effect. If I run sysctl -p, then they do. This wouldn't be a huge issue, except that I can't figure out how to restart the lock manager without rebooting. I would really like to know why sysctl.conf isn't working at boot, but I'd settle for just being able to restart the lock manager. This is on Ubuntu server 10.04.2, kernel 2.6.32-31-server. I know some daemons check the permissions on their config files and refuse to work if they're too permissive, but sysctl.conf is 644 root:root, which I'm pretty sure is the default.

  • Setting up Apache with multiple virtual host when using Plone 4.1

  • Using AT on Ubuntu to Background Downloads (w/ Queue)

    - by Nicholas Yost
    I am writing a PHP script, but I want to use the AT command in Ubuntu to fetch a remote file via WGET. I'm basically looking to background the process, so PHP can finish fairly quickly. I cannot find any questions on here about how to use both, but I basically want to do the following pseudo-code: <?php exec('at now -q queuename wget http://path.to/remote/file.ext'); ?> Additionally, I'd like to queue this between providers. I'd like to have each path.to have its own queue, so I only download one file from each provider at a time. Meaning: <?php exec('at now -q remote wget http://path.to/remote/file.ext /local/path'); exec('at now -q vendorone wget http://vendor.one/remote/file.ext /local/path'); exec('at now -q vendortwo wget http://vendor.two/remote/file.ext /local/path'); exec('at now -q vendorone wget http://vendor.one/remote/file.ext /local/path'); ?> This should download the files from path.to, vendor.one, vendor.two immediately, and when the first file is finished downloading from vendor.one, it starts the second file. Does that make sense? I can't find anything like this anywhere on the web, much less on SO/SF. If we can use the crontab to run a one-off wget command, thats fine too.

  • Outlook error-'Can't open e-mail folders.You must connect to Exchange w/ current profile before you can sync folders w/ your Outlook data file'

    - by Emilio
    Note that the error message I put in the title of this question is abbreviated. The actual error message is below. I have an Exchange account and using Outlook 2010 as the client. I run in Cached Exchange Mode and have an .OST file locally. Recently I uninstalled and reinstalled office. I set up a new mail profile when prompted by Outlook 2010 upon first execution of the program. In my initial attempt, I pointed the data file at my existing OST file. In my second attempt, I had Outlook create a fresh empty file. In both cases I'm getting the error 'Cannot open your default e-mail folders. You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with your Outlook data file (.ost).', also shown in this screenshot -- http://drop.io/4rc9v9o/asset/outlook-error-png. I don't know how to connect with the current profile - that's what I thought I did when I created a new .OST file? I've had this problem for several days so my OST file is now out of date. Once I get things running I obviously want my active mailbox to update the OST, not the other way around.

  • Load Sharing Regarding Large Websites

    - by JHarley1
    Hello, I have a question regarding Load Sharing for large websites. My Understanding: So if you have a website that has millions of fits a day you will need to have an architecture that can support this sort of pressure. You can either do one or two things: Invest in a single large server that has huge amounts of processing power, memory and storage (such as Microsoft's TerraServer). Spread the load of your website across a number of machines. Let me tackle the second approach, so you have a collection of machines all running Web Server Software and all having access to identical copies of the websites pages. You can either spread the load across these machines using a cyclic pattern in a DNS or you can use a Load Ballancing Switch. The advantages of this approach is: - Redundancy - servers can fail and the others would "pick up the slack" - Incremental - the ability to easily add new machines to this set-up. My Question's Is there a Virtual approach to this issue of load balancing now? If the website runs from a database - is there still only a single copy of the database? If a user had a session running on one Server (e.g. they had gone to www.example.org and had been assigned to Server 2 - were they had created a session) if they refreshed the website (and were allocated Server 3) would they still have their session? What are the other disadvantages associated with Load Balancing? Many Thanks, J

  • Samba PDC share slow with LDAP backend

    - by hmart
    The scenario I have a SUSE SLES 11.1 SP1 machine as Samba master PDC with LDAP backend. In one share there are Database files for a Client-Server application. I log XP and Windows 7 machines to the local domain (example.local), the login is a little slow but works. In the client computers have an executable which opens, reads and writes the database files from the server share. The Problem When running Samba with LDAP password backend the client application runs VERY SLOW with a maximum transfer rate of 2500 MBit per second. If disable LDAP the client app speed increases 20x, with transfer rate of 50Mbit/sec and running smoothly. I'm doing test with just two users and two machines, so concurrency, or LDAP size shouldn't be the problem here. The suspect LDAP, Smb.conf [global] section configuration. The Question What can I do? I've googled a lot, but still have no answer.

  • BTrFS crashhhh?

    - by bumbling fool
    I create a new BTrFS raid10 file system using two 250GB drives and the second partition on a third 80GB drive. I create a subvol and snapshot. I mount the snapshot and start copying 8GB of data to it. It gets to around 1GB and the Desktop disappears and what looks like a non interactive terminal comes up with dump/crash information. I don't have a camera handy or I'd take a picture and post it. It basically looks like stack trace info. CTRL-ALT F7 will eventually bring back the Desktop though but the entire BTrFS portion of the OS is hung and non responsive until I reboot. I've reformated and reproduced this problem 3 times now and I'm about to give up :( I realize it is possible this problem is not entirely BTrFS' fault because I'm on natty which is still alpha. More granular details in case I'm an idiot: 1) Create FS: sudo mkfs.btrfs -m raid10 -d raid10 /dev/sda2 /dev/sdb /dev/sdc 2) Initial temporary mount: mkdir /btrfs && sudo mount -t btrfs /dev/sda2 /btrfs 3) Create subvol btrfs s c /btrfs/vm 4) Create initial snapshot: (optional) btrfs s sn /btrfs/cantremember.snap.something 5)unmount /btrfs and mount /btrfs/vm sudo mount -t btrfs -o subvol=vm /dev/sda2 /btrfs/vm 6) Copy data to subvolume. 7) Balance data across drives: (optional) btrfs f bal <path> (never get to this step 7...) Am I doing something wrong?

  • Apache server configuration name resolution (virtual host naming + security)

    - by Homunculus Reticulli
    I have just setup a minimal (hopefully secure? - comments welcome) apache website using the following configuration file: <VirtualHost *:80> ServerName foobar.com ServerAlias www.foobar.com ServerAdmin [email protected] DocumentRoot /path/to/websites/foobar/web DirectoryIndex index.php # CustomLog with format nickname LogFormat "%h %l %u %t \"%r\" %>s %b" common CustomLog "|/usr/bin/cronolog /var/log/apache2/%Y%m.foobar.access.log" common LogLevel notice ErrorLog "|/usr/bin/cronolog /var/log/apache2/%Y%m.foobar.errors.log" <Directory /> AllowOverride None Order Deny,Allow Deny from all </Directory> <Directory /path/to/websites/> Options -Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> </VirtualHost> I am able to access the website by using www.foobar.com, however when I type foobar.com, I get the error 'Server not found' - why is this? My second question concerns the security implications of the directive: <Directory /path/to/websites/> Options -Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> in the configuration above. What exactly is it doing, and is it necessary?. From my (admitedly limited) understanding of Apache configuration files, this means that anyone will be able to access (write to?) the /path/to/websites/ folder. Is my understanding correct? - and if yes, how is this not a security risk?

  • Webservice randomly dropping connections - possibly due to firewall nonevent data?

    - by adam
    I have a hosted webapp which requests data from a REST webservice in our office. Each page calls one (or several) webservices, which go from our host, via our firewall (a Watchguard Firebox) to a server in our office. All of a sudden, the app has dramatically slowed. We have determined that the webservice is timing out at random when called externally (it's fine when called within the office network). I'm pretty certain it's our connection which is dropping the webservice call, so I've written a quick php/curl script which calls the webservice over many iterations and shows the various timings. Below is an example output, showing both a failed and a successful call (with a 5 second timeout): http_code namelookup_time connect_time pretransfer_time starttransfer_time total_time 1 0 0.000096 0.0342 0.0000 0.0000 0.0342 2 200 0.000052 0.0332 0.1327 0.1751 0.1752 As per iteration #1 above, failed requests seem to be failing between connect and pretransfer. I'm not sure if this shows that the connection is successfully past the firewall, or could the firewall still cause an issue? Our firewall is showing a series of nondata event log messages for the relevant access rule. Our IT team tells me these are routine, although I can find no mention of these in Google. I'm not sure if this fits in between connect and pretransfer. Having elinated the webservice server (by testing internally) and the live webapp (by testing different code on different external servers, I am left suspecting the connection to the office. Could the firebox nondata events be causing a problem between connect and pretransfer?

  • Unable to ping domain.local, but can ping server.domain.local

    - by Force Flow
    I have a single windows 2008 server running active directory, group policy, and DNS. DHCP is running from the firewall (this is because there are multiple branch locations, and each location has its own firewall supplying DHCP. But, for this problem, the server and workstation are at the same location). On an XP workstation, if I try to visit \\domain.local or ping domain.local, the workstation can't find it. A ping returns Ping request could not find host domain.local. If I try to visit \\server or \\server.domain.local or ping server or server.domain.local, I'm able to connect normally. If I ping or visit domain.local on the server, I'm able to connect normally. A-Records are in place in the DNS service for server, domain.local, and server.domain.local. A reverse lookup zone also is enabled and PTR records are in place. If I wait 20-30 minutes, I am eventually able to ping and visit domain.local--but, when attempting to ping, it takes 30 second to return an IP address. I am also unable to join a new workstation to the domain during this wait period. If I try, the error message returned is "network path not found". Is there something I'm missing?

  • Slow File Copy observed copying 40GB files across network to iSCSI device

    - by Rick
    Here's a curious ones for the gurus: Setup: Source Machine: Windows Server 2003 R2 machine with local hard drive. VHD file of 40GB. 1 x 1Gbps network card, Cat6 cable, switch. Target Machine: Windows Server 2008 R2 machine with iSCSI connection to iSCSI target on separate machine (1TB, RAID5). 1 x 1Gbps network card, Cat6 cable, connected to same switch as for Source Machine. Second 1Gbps network card, Cat6 cable, connected via isolated switch to the iSCSI target. Switches are Netgear JGS524 model (web managed). If I copy from the Win2003R2 machine to Win2008R2 machine local drive I get 40GB in 45 minutes, 36 seconds. If I copy from the Win2008R2 machine to the iSCSI target (local drive to iSCSI target) I get 40GB in 37 minutes 56 seconds. If I copy from the Win2003R2 machine to the iSCSI target via the Win2008R2 machine I get 40GB in 3 hours, 50 minutes, 24 seconds. All copies were done via the following command issued on the Win2008R2 box: XCOPY <source> <target> /J XCOPY /J - Copies using unbuffered I/O. Recommended for very large files. So, what's the bit I'm missing here? Why does a back-to-back copy take in total 1 hour, 23 minutes, 32 seconds when a "straight through" copy take almost 3 times as long? Switches show no errors, network hovers around the 3% utilisation mark for the duration of the copy (whereas the "back-to-back" copies are around the 25% utilisation mark). What have I missed?
