  • Prevent 'Run-time error '7' out of memory' error in Excel when using macro

    - by MasterJedi
    I keep getting this error whenever I run a macro in my excel file. Is there any way I can prevent this? My code is below. Debugging highlights the following line as the issue: ActiveSheet.Shapes.SelectAll My macro: Private Sub Save() Dim sh As Worksheet ActiveWorkbook.Sheets("Report").Copy 'Create new workbook with Sheets("Report"(2)) as only sheet.

  • What would cause my SendMail server not to acknowledge receiving a TCP Sequence?

    - by Mike B
    My TCP/IP Stack knowledge is a little rusty so please bear with me.... I have a CentOS 5.7 server with SendMail and am having seeing intermittent timeout issues sending email (particularly larger email) to other remote domains. It doesn't happen with all attachments or recipient domains. Just some. After some extended troubleshooting, I think I've narrowed it down to TCP Sequences not being acknowledged. Here's a breakdown of the TCP session from a packet capture I collected directly on my MTA (fooMTA): Packet 1 - 11: Standard TCP handshake followed by initial SMTP conversation. No errors. Packet #12 Recipient MTA: TCP sequence 231. Ack 91. Packet #13 FooMTA: TCP sequence 91. Ack 305. Packet #14 FooMTA: TCP sequence 1115. Ack 305. Packet #15 Recipient MTA: TCP sequence 305. Ack 2495. Packet #16 FooMTA: TCP sequence 2495. Ack 305. Packet #17 FooMTA: TCP sequence 5255. Ack 305. Packet #18: Recipient MTA: TCP sequence 305. Ack 5255. Packet #19: FooMTA: TCP sequence 6635. Ack 305. Packet #20: FooMTA: TCP sequence 8015. Ack 305. Packet #21: Recipient MTA: TCP Sequence 305. Ack 8015. Packet #22: FooMTA: TCP Sequence 10775. Ack 305. Packet #23: FooMTA: TCP Sequence 13535. Ack 305. Packet #24: Recipient MTA: TCP sequence 305. Ack 10775 Packet #25: FooMTA: TCP Sequence 14915. Ack 305 It keeps going like this with my server still thinking it hasn’t received sequence 305… in response the remote side eventually retransmits its prior data thinking that it never arrived. Eventually the gap gets so large that no new data is sent and the remote MTA keeps retransmitting old stuff. This contributes to an exponential backoff and eventually the remote side gives up. What’s strange to me is that I see the “missing” TCP sequence (305 in this case) arriving back to my server (via a packet capture collected directly from fooMTA) So I don’t get why my server keeps asking for it. Could this be firewall related? What would be the next step in troubleshooting?

  • How to setup Proxy Cache with Nginx and Passenger

    - by tiny
    I use Nginx and Passenger for my rails application. I want to use proxy cache to cache my pages. However, every request go direct to my rails application. I don't know what wrong with my configuration.

  • if I define `my_domain`, postfix does not expand mail aliases

    - by Norky
    I have postfix v2.6.6 running on CentOS 6.3, hostname priest.ocsl.local (private, internal domain) with a number of aliases supportpeople: [email protected], [email protected], [email protected] requests: "|/opt/rt4/bin/rt-mailgate --queue 'general' --action correspond --url http://localhost/", supportpeople help: "|/opt/rt4/bin/rt-mailgate --queue 'help' --action correspond --url http://localhost/", supportpeople If I leave postfix with its default configuration, then the aliases are resolved correctly/as I expect, so that incoming mail to, say, [email protected] will be piped through the rt-mailgate mailgate command and also be delivered (via the mail server for ocsl.co.uk (a publicly resolvable domain)) to [email protected], user2, etc. The problem comes when I define mydomain = ocsl.co.uk in /etc/postfix/main.cf (with the intention that outgoing mail come from, for example, [email protected]). When I do this, postfix continues to run the piped command correctly, however it no longer expands the nested aliases as I expect: instead of trying to deliver to [email protected], user2 etc, it tries to send to [email protected], which does not exist on the upstream mail server and generates NDRs. postconf -n for the non-working configuration follows (the working configuration differs only by the "mydomain" line. alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix debug_peer_level = 2 html_directory = no inet_interfaces = all inet_protocols = all mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = $myhostname, localhost.$mydomain, localhost mydomain = ocsl.co.uk newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES sample_directory = /usr/share/doc/postfix-2.6.6/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop unknown_local_recipient_reject_code = 550 We did have things working as we expected/wanted previously on an older system running Sendmail.

  • ntpdate works, but ntpd can't synchronize

    - by dafydd
    This is in RHEL 5.5. First, ntpdate to the remote host works: $ ntpdate XXX.YYY.4.21 24 Oct 16:01:17 ntpdate[5276]: adjust time server XXX.YYY.4.21 offset 0.027291 sec Second, here are the server lines in my /etc/ntp.conf. All restrict lines have been commented out for troubleshooting. server 127.127.1.0 server XXX.YYY.4.21 I execute service ntpd start and check with ntpq: $ ntpq ntpq> peer remote refid st t when poll reach delay offset jitter ============================================================================== *LOCAL(0) .LOCL. 5 l 36 64 377 0.000 0.000 0.001 timeserver.doma .LOCL. 1 u 39 128 377 0.489 51.261 58.975 ntpq> opeer remote local st t when poll reach delay offset disp ============================================================================== *LOCAL(0) 127.0.0.1 5 l 40 64 377 0.000 0.000 0.001 timeserver.doma XXX.YYY.22.169 1 u 43 128 377 0.489 51.261 58.975 XXX.YYY.22.169 is the address of the host I'm working on. A reverse lookup on the IP address in my ntp.conf file validates that the ntpq output is correctly naming the remote server. However, as you can see, it appears to just roll over to my .LOCL. time server. Also, ntptrace just returns the local time server, and ntptrace XXX.YYY.4.21 times out. $ ntptrace localhost.localdomain: stratum 6, offset 0.000000, synch distance 0.948181 $ ntptrace XXX.YYY.4.21 XXX.YYY.4.21: timed out, nothing received ***Request timed out This looks like my ntp daemon is just querying itself. I am thinking about the possibility that the router-I-don't-control between my test network timeserver and the corporate network timeserver is blocking on source port. (I think ntpdate sends on port 123, which gets it around that filter and is why I can't use it while ntpd is running.) I have email in to the network folks to check that. Finally, telnet XXX.YYY.4.21 123 never times out or completes a connection. The questions: What am I missing, here? What else can I check to try to figure out where this connection is failing? Would strace ntptrace XXX.YYY.4.21 show me the source port ntptrace is sending from? I can deconstruct most strace calls, but I can't figure out the location of that datum. If I can't directly examine the gateway router between my test network and the timeserver, how might I build evidence that it's responsible for these disconnections? Alternately, how might I rule it out?

  • Windows 7 & Virtual PC and Internet (gateway) problems on host PC

    - by Mufasa
    I upgraded to Windows 7 on a PC that is a few years old. The CPU was one revision away from having Hyper-V on it. So, I had to install Microsoft Virtual PC 2007 (v6.0.156.0) to run full XP instances instead of the seamless XP virtualization that is advertised so much. That's fine though; the 'older' version is useful since I use it to run different versions of the whole XP/IE stack for testing. (I'm a web developer.) ...And for the one 16-bit application we still use at the office for scheduling. * sigh * The virtual instances work fine, including networking. My issue is that after a reboot or coming out of sleep mode, my host Windows 7 won't connect to the Internet. It will connect to the local network fine. If I disable the "Virtual Machine Network Services" item (I'll call "VMNS" from here on) in the LAN Connection properties box, it starts working. But than the Virtual PC instances lose their network connectivity. If I re-enable VMNS again in the same instance, everything works (Internet on host and in the virtualized instances). But after the next reboot/sleep cycle this starts over. The route table gave me a clue though. When doing a cycle w/ VMNS enabled: IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 On-link 10.0.3.51 20 0.0.0.0 0.0.0.0 10.0.10.10 10.0.3.51 276 ... After VMNS is disabled, the first route goes away. I assume that is for VMNS to intercept virtualized instance's network connections and forward them correctly? Just a guess though. More info: I checked my Firewall settings and Services (because I'm sort of a control nazi and turn off a lot) but couldn't find anything that made sense and if turned on changed anything. So it might be something there I'm missing, but I don't know what. My current hacked solution: So, I figured I'd mess with the routes myself to see if that helped, it did. If I run a route delete 0.0.0.0 on the universal (0.0.0.0) gateway routes, and add back in just the 2nd line with route add 0.0.0.0 mask 0.0.0.0 10.0.10.10--the one that points to my actual gateway (10.0.10.10)--then I don't have to mess with the disable/enable cycle of VMNS, and everything works. Running those two commands is faster then bringing up connection options and disabling and re-enabling VMNS, but I still don't want to have use that hack script every boot either. (Oh, and I also tried messing with hard-coding TCP/IP settings in my network adapter, including setting high metrics, etc., but that didn't help either.) Any suggestions on the right way to fix this?

  • after building in more ram, bios/debian does nothing [closed]

    - by derty
    My private server has 2x1gb Ram working with a 64bit Debian and an Q6600 Intel. This runs 2 virtual mashines on it each one recives 512mb RAM. Which you can immagine is a bit tight for the hole system. Now i got 2x2gb ram from a friend. I'm not sure if thery are clocking at the same speed, but i'm sure my power adaptor is not on his limit and can handle that. So there are 2 ram sockets left at the mainboard. I shuted down the system and build in the 4 gigs and looked what happen. After pressing the start button, everything gets noisy as known BUT the screen shows nothing, not even the bios stuff it usally does. Why isn't the system booting? I can immagine that it does not direkt link between booting debian and the bios not showing a thing. Or is it Grub? I mounted the system disk, and i can see it, switch folders write stuff with "vim" it does not seems like there is a problem.

  • Need help troubleshooting highly variable ping times

    - by Elliot.Bradshaw
    I'm at work using Citrix (think Remote Desktop) to connect to client sites. With my job I have to write a fair bit of code while I'm connected remotely via Citrix, so the latency of my internet connection is important. If I'm getting ping times above 250ms, then it becomes almost impossible to scroll, click or type with accuracy. Recently my Comcast business internet has been exhibiting highly variable ping times. If I ping google.com, I'll get pings that range from 9ms all the way up to 1300ms. The problem seems to be at its worst during the hours of 1PM to 4:30PM. Outside of those hours and the variance in pings settles down, mostly between 9ms and 50ms. The signal to noise ratio and upstream power are both fine on my modem--the values are here: http://pastebin.com/D4hWGPXf I ran a trace route from my computer to google.com (the results of which are here: http://pastebin.com/GcdjYvMh) and did another test ping to the IP of the first hop outside of our local network (73.98.44.1)--the variance in ping times existed in exactly the same manner as if I were pinging Google. Connecting directly to the cable modem by CAT5 makes no difference. Here is a screenshot demonstrating the variance of the ping times: http://postimage.org/image/haocdeauv/full/ -- as you can see it can get pretty bad. Three Comcast techs have been out (two of them were here when the problem wasn't happening) and they as well as the regional tier 2 Comcast support were unable to diagnose the problem. I now have a ticket open with tier 3 support, but have yet to hear back from them. Does anyone know what could cause these sorts of problems or have any idea from the traceroute above where it could be originating? The regional tier 2 guy tried to tell me that what I'm seeing is normal--are highly variable ping times like that ever acceptable? Anything I should ask Comcast to do or look at to get this problem fixed? Any tips/advice much appreciated! Edit: This is Comcast cable internet at a small start-up, we've ruled out congestion in our private LAN as a cause (i.e., no one's watching YouTube when the pings become variable). Update: Tier 3 Comcast support advised swapping out the modem, a tech came here today and did that--same problem persists.

  • How intrusive is using VPN?

    - by Slade
    My company lets us work from home sometimes using VPN (during weather emergencies and stuff). When logging in a big window comes up that says the network is private and for employees only and that there's no right to privacy while using VPN. It makes sense that they don't want people poking around their network but I wonder if the company can use the connection to look around my computer while I'm connected. I'm not entirely computer-illiterate but I'm not a networks person at all so the technical documents I've found don't help me. Is that possible, and if so to what degree? UPDATE Thanks Mark. The funneling thing is what I was really asking about. Mostly I was worried that I would already have some IM conversation open or log into eBay forgetting that the VPN was open and that my company IT people would see it or that they would log my eBay password. Thanks again. ANOTHER UPDATE What if my son wants to play online poker or Warcraft etcetera while I have VPN on to work? Can my company think I'm the one playing if I am not typing often?

  • Viewing local websites on my iOS device over Wi-fi

    - by John
    Trying to view some local html/css/js files in a mobile browser on my iOS device. Thought maybe file-sharing would be an option, and is, but I'm not completely satisfied with it. Any time I try to do the following an error occurs. Web sharing is on and available at http://192.168.1.101/~user but I have to manually copy the files in. If I try to symlink a folder in so that the address could be viewed at ''~user/some_dir by issuing $ ln -s /Users/user/dev/some_dir ~/Sites/ then I get a 403 forbidden error. I've tried to remedy this by modifying a user.conf file in /private/etc/apache2/ and using the following syntax: <Directory "/Users/user/Sites/"> Options Indexes MultiViews SymLinks AllowOverride None Order allow,deny Allow from all </Directory> but nope, still doesn't work. I get a 403 error. If I try to symlink each individual file in instead of using a directory as a sub-directory, same error. Any help would be greatly appreciated! I'd just like to symlink directories into the ~/Sites one and browse them on my iOS device over wifi. I'm on OS X 10.7 Lion trying to connect with iOS 5.

  • Looking for a new, free firewall (Sunbelt has a huge hole)

    - by Jason
    I've been using Sunbelt Personal Firewall v. 4.5 (previously Kerio). I've discovered that blocking Firefox connections in the configuration doesn't stop EXISTING Firefox connections. (See my post here yesterday http://superuser.com/questions/132625/sunbelt-firewall-4-5-wont-block-firefox) The "stop all traffic" may work on existing connections - but I'm done testing, as I need to be able to be selective, at any time. I was using the free version, so the "web filtering" option quit working after some time (mostly blocking ads and popups), but I didn't use that anyway. I used the last free version of Kerio before finally having to go to Sunbelt, because Kerio had an unfixed bug where you'd eventually get the BSOD and have to reset Kerio's configuration and start over (configure everything again). So I'm looking for a new Firewall. I don't like ZoneAlarm at all (no offense to all it's users that may be here - personal taste). I need the following: (Sunbelt has all these, except *) - 1. Be able to block in/out to localhost (trusted)/internet selectively for each application with a click (so there's 4 click boxes for each application) [*that effects everything immediately, regardless of what's already connected]. When a new application attempts a connection, you get an allow/deny/remember windows. - 2. Be able to easily set up filter rules for 'individual application'/'all applications,' by protocol, port/address (range), local, remote, in, out. [*Adding a filter rule also doesn't block existing connections in Sunbelt. That needs to work too.] - 3. Have an easy-to-get-to way to "stop all traffic" (like a right click option on the running icon in the task bar). - 4. Be able to set trusted/internet in/out block/allowed (4 things per item) for each of IGMP, ping, DNS, DHCP, VPN, and broadcasts. - 5. Define locahost as trusted/untrusted, define adapter connections as trusted/untrusted. - 6. Block incoming connetions during boot-up and shutdown. - 7. Show existing connections, including local & remote ip/port, protocol, current speed, total bytes transferred, and local ports opened for Listening. - 8. An Intrusion Prevention System which blocks (optionally select each one) known intrustions (long list). - 9. Block/allow applications from starting other applications (deny/allow/remember window). Wish list: A way of knowing what svchost.exe is doing - who is actually using it/calling it. I allowed it for localhost, and selectively allowed it for internet each time the allow/deny window came up. Thanks for any help/suggestions. (I'm using Windows XP SP3.)

  • Mac OSX 10.8 Server DNS Domain Routing

    - by Oldek
    I just cant seem to figure out the logic in how to configure my Mac Server. So I have set up an DNS, which will take the domain and all subdomains and point towards an IP. File: db.mydomain.com (in /var/named/) mydomain.com. 10800 IN SOA mydomain.com. admin.mydomain.com. ( 2012110903 ; serial 3600 ; refresh (1 hour) 900 ; retry (15 minutes) 1209600 ; expire (2 weeks) 86400 ; minimum (1 day) ) 10800 IN NS mydomain.com. 10800 IN A 10.0.1.2 www.mydomain.com. 10800 IN A 10.0.1.2 So I want all of these requests to be requested to the 10.0.1.2 server, as I run 2 servers in my cluster. This one has always handled the requests, and now I want to add a server in between. So the server in between will get all the signals from my router which NAT the trafic coming from outside. So after setting this up and trying to point my port 80 towards my new server which will be the middle point, it doesn't work. Is it even possible to do it this way? First server: Mac Second server: Linux So what I try to achieve once more: 1. User goes to mydomain.com or www.mydomain.com 2. User request gets handled by my first server 3. First server refers to a local server, which is only available locally (it is configured to allow requests on port 80 and handle them) 4. Second server receives signal 5. Second server returns a request (either directly send to user or send through first server, whichever is most secure and configurable) I also want to be able to set up domains that lead to other servers in the future, and some that are only available within the VPN. (If that changes anything) I hope some kind soul could help me with this, it is really cumbersome for my mind to get the logic here. Do I have to configure my other server in any way? /Marcus

  • crontab not running on VirtualBox unless I'm logged in

    - by Mike
    I am running Ubuntu Server 9.04 in VirtualBox on my work PC as a development environment. I have some scripts that I've put in my user's crontab that run throughout the day while I'm SSHed into the VM. Last night, I closed PuTTy and all of my other running applications (except for VirtualBox and the VM) and went home. I came back this morning to discover that my cron jobs didn't run at all, yet when I SSHed into the VM, the next scheduled job ran. I set the schedule to 5min to test, disconnected again, and the jobs stopped running on schedule. They seem to only run if I'm logged in to the machine. Obviously, I want them to run on schedule even if I'm not logged in to the VM, otherwise there's no point. Is there something I've failed to configure correctly? New Information: There are now 3 entries in /var/log/cron.log saying the following "Mount of private directory return code [256]"... the entries correspond to when the cron job is supposed to run. I thought they are supposed to run as my userid? Why would my own userid be unable to run a script in my home directory?

  • My nameserver isn't registered?

    - by jflory7
    My problem is that I am trying to set my domain's nameservers to the nameservers of my dedicated server. My domain is hosted by Namecheap, and everytime I try to input the two nameservers for my private server, one of them is rejected for being unregistered. My dedicated server's control panel is managed through Parallels Plesk 11.5, and the nameservers provided to me are one from the actual provider, OVH (sdns1.ovh.ca), and the other is an actual unique nameserver that points directly to my specific dedicated server. Previously, for another domain I own, I was successfully able to get Namecheap to take the nameserver without an error, so I know this is possible. I know that it works for one of my other domains. After being redirected by Namecheap to contact the server provider, I called OVH and they said it was something I would have to do myself. One interesting detail the OVH representative mentioned was that he saw that my port 53 was closed, which is the port that handles DNS. The only problem is that I have no idea or knowledge as how to open this port back up. So, my final question is how can I get this nameserver working in Namecheap to point to my dedicated server? If you need any more details, feel free to ask for clarification.

  • GPG - why am I encrypting with subkey instead of primary key?

    - by khedron
    When encrypting a file to send to a collaborator, I see this message: gpg: using subkey XXXX instead of primary key YYYY Why would that be? I've noticed that when they send me an encrypted file, it also appears to be encrypted towards my subkey instead of my primary key. For me, this doesn't appear to be a problem; gpg (1.4.x, macosx) just handles it & moves on. But for them, with their automated tool setup, this seems to be an issue, and they've requested that I be sure to use their primary key. I've tried to do some reading, and I have the Michael Lucas's "GPG & PGP" book on order, but I'm not seeing why there's this distinction. I have read that the key used for signing and the key used for encryption would be different, but I assumed that was about public vs private keys at first. In case it was a trust/validation issue, I went through the process of comparing fingerprints and verifying, yes, I trust this key. While I was doing that, I noticed the primary & subkeys had different "usage" notes: primary: usage: SCA subkey: usage: E "E" seems likely to mean "Encryption". But, I haven't been able to find any documentation on this. Moreover, my collaborator has been using these tools & techniques for some years now, so why would this only be a problem for me?

  • How can I document and automate a system's configuration?

    - by Diomidis Spinellis
    Having a system's configuration represented by its current state is risky, inefficient, and opaque. At some point you may be left with an unsupported system and no upgrade path. Then configuring a new system compatible with the old is a process or trial and error. Furthermore, if at some point the system is damaged the only option is to go back to the most recent full backup, and try to remember what changes followed from that point. Also, the only way to create a system compatible with the original is through a complete dump/restore. Finally, in such a setup there's no way to know how you solved a particular problem; the only thing you can do is to look at the corresponding configuration files and try to guess what you changed to achieve the desired effect. Currently for each system I maintain, I keep a log file where I record all system administration activity, starting from the installation: installation options, added packages, changes in configuration files, updates, problem fixes etc. In theory this allows me to (manually) replay all changes to arrive at the current state, or to unroll an erroneous change by executing the reverse commands. However, this process is also inefficient, error-prone, and relies on human judgment. Another thing I've tried is to put /etc configuration files under version control with git. This helps me document the changes automatically and also apply them on a clean setup. But it's not without problems: git has to run under sudo, passwords and private keys may be stored in the repository, installed packages can't be meaningfully tracked, and git will have a fit if I try to extend this approach to all the system's directories. I've also thought about performing all changes through shell scripts or makefiles, but I think this process will require a lot of effort and will be fragile. Are there some better methods or tools that I'm missing?

  • unable to connect site to different port

    - by JohnMerlino
    I have a domain was registered at godaddy named http://mysite.com/. I logged into godaddy and I went to All Products Domains Domain Management. I clicked on the appropriate domain and it took me to the Domain Details page. I clicked Launch under DNS Manager and it took me to the Zone File Editor. I noticed that notify.mysite.com was pointing to an IP address pointing to a dead server, so I switched it to an operating server. Then I pinged the domain to see where it was pointing to and it was correctly pointing to the working server. So I copied the default configuration under sites-available: sudo cp default notify.mysite.com. And then I made some edits to it to have it point to a different document root to serve files at a different port: Listen 1740 Listen 64.135.xx.xxx:1740 #I also tried this as well: NameVirtualHost 64.135.xx.xxx:1740 <VirtualHost 64.135.xx.xxx:1740> ServerAdmin [email protected] ServerName notify.mysite.com DocumentRoot /var/www/test/public <Directory /var/www/test/public> Order allow,deny allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost> Then I enabled the virtual host. Then I went to the document root and added an index.html file with some text in it. Then I restarted apache. The restart gave no errors. Then I type the correct domain in URL: http://notify.mysite.com:1740/ and I get: Oops! Google Chrome could not connect to notify.mysite.com:1740 Somehow it took out all my other sites. Now even the ones that were responding on port 80 are no longe responding, even though I did not touch the virtual hosts for them. I get this message now: Oops! Google Chrome could not connect to mysite.com However, ping responds: ping mysite.com PING mysite.com (64.135.12.134): 56 data bytes 64 bytes from 64.135.12.134: icmp_seq=0 ttl=49 time=20.839 ms 64 bytes from 64.135.12.134: icmp_seq=1 ttl=49 time=20.489 ms The result of telnet: $ telnet guarddoggps.com 80 Trying 64.135.12.134... telnet: connect to address 64.135.12.134: Connection refused telnet: Unable to connect to remote host

  • Nginx config - serving index.html not working

    - by Bill
    I can't figure out how to redirect / to index.html. I've gone through the threads on serverfault and I think I've tried every suggestion including: rewrite statements within location / index index.html at the server level, within location / and within static content moving node.js proxy statements to location ~ /i instead of within location / Obviously something is wrong somewhere else in my configuration. Here is my nginx.conf: worker_processes 1; pid /home/logs/nginx.pid; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; error_log /home/logs/error.log; access_log /home/logs/access.log combined; include sites-enabled/*; } and my server config located in sites-enabled server { root /home/www/public; listen 80; server_name localhost; # proxy request to node location / { index index.html index.htm; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-NginX-Proxy true; proxy_pass http://127.0.0.1:3010; proxy_redirect off; break; } # static content location ~ \.(?:ico|jpe?g|jpeg|gif|css|png|js|swf|xml|woff|eot|svg|ttf|html)$ { access_log off; add_header Pragma public; add_header Cache-Control public; expires 30d; } gzip on; gzip_vary on; gzip_http_version 1.0; gzip_comp_level 2; gzip_proxied any; gzip_min_length 1000; gzip_disable "msie6"; gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; } Everything else is working just fine. Requests get proxied to node correctly and static content is served correctly. I just need to be able to forward requests made to / to /index.html.

  • OSX server setup suggestions

    - by Tom
    I am looking into the possibility to setup an OSX server for my employees, and would like some input on what is the best approach to meet my needs, and perhaps some suggestions if I am moving in the wrong direction. I am thinking of a Mac Mini OSX server, and are not sure if my needs will be met, and what possibilities are out there. I want these capabilities: - Groups/Users managed on server - Shared folders and private folders for users/groups - Access to activated services - Server hosting software for the users (developing tools ++) - Similar to Windows Terminal Server - Virtual desktop environment (both local and over internet/VPN) - Possible to access trough Mac and Windows The reason I am looking at OSX server is that my employees almost only work in OSX environment, and I want to offer the capabilities to logon to the server trough some kind of terminal software, and have full access to their work OSX environment and software on their mac or pc, from anywhere they might be. Instead of having to have multiple setups and need for spending alot of time installing and setting up needed software on every client. This is a small business, where some work on local network, and others from the internet, preferably trough VPN. But a terminal server solution, that are fast and easy to manage would be perfect for our needs. So if anyone have any experience with a similar setup, please let me know what you did, and your experiences with your setup.

  • ESX 3.5 refuses to update

    - by Speeddymon
    I have a set of ESX 3.5 servers in 2 different datacenters. One is DR, one is production. They are on the same vlan and so I can access any of them on the private network from my vCenter server. Last month, as a learning experience (I hadn't dealt with ESX much before), I updated the DR server. Other than finding out that a couple of bundles had to be installed manually in order to get the rest to install from vCenter, it went off without a hitch. Now, I'm trying to do the same for our production servers and it is not working. I've googled around for the error I get during scan, and investigate loads of different solutions (editing the integrity file, checking DNS, etc) -- I did install the 2 bundles that had to be installed manually already -- but scan from vCenter is just not working. Side note: I did just scan the DR server again and that scan works fine so shouldn't be a problem with vCenter that has cropped up recently -- it has to be something else. The error I get is: Patch metadata for (servername) missing. Please download updates metadata first. Failed to scan (servername) for updates. I'm all out of ideas on how to make this work, so any help would be hugely appreciated.

  • Serving protected files using Nginx's X-Accel-Redirect header

    - by andybak
    I'm trying to serve protected files using this directive in my nginx.conf: location /secure/ { internal; alias /home/ldr/webapps/nginx/app/secure/; } I'm passing in paths in the form: "/myfile.doc" and the file's path would be: /home/ldr/webapps/nginx/app/secure/myfile.doc I just get 404's when I access "http: //myserver/secure/myfile.doc" (space inserted after http to stop ServerFault converting it to a link) I've tried taking the trailing / off the location directive and that makes no difference. Two questions: How do I fix it! How can I debug problems like this myself? How can I get Nginx to report which path it's looking for? error.log shows nothing and access.log just tells me which url is being requested - this is the bit I already know! It's no fun trying things randomly without any feedback. Here's my entire nginx.conf: daemon off; worker_processes 2; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; server { listen 21534; server_name my.server.com; client_max_body_size 5m; location /media/ { alias /home/ldr/webapps/nginx/app/media/; } location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; fastcgi_pass unix:/home/ldr/webapps/nginx/app/myproject/django.sock; fastcgi_pass_header Authorization; fastcgi_hide_header X-Accel-Redirect; fastcgi_hide_header X-Sendfile; fastcgi_intercept_errors off; include fastcgi_params; } location /secure { internal; alias /home/ldr/webapps/nginx/app/secure/; } } } EDIT: I'm trying some of the suggestions here So I've tried: location /secure/ { internal; alias /home/ldr/webapps/nginx/app/; } both with and without the trailing slash on location. I've also tried moving this block before the "location /" directive. The page I linked to has ^~ after 'location' giving: location ^~ /secure/ { ...etc... Not sure what that signifies but it didn't work either!

  • Nginx Load Balancer 403 error

    - by user64473
    I am trying to install nginx as a load balancer with apache backends, so that when I point my sites to the nginx server it serves up the content from the apache backend. I have the apache configuration set up correctly on both (i.e when I go to the site on the apache servers it works great) but when I use the nginx load balancer as the site I get 403 error. I have no idea why as it isn't even accessing any files on the server, thusly there aren't any files to be forbidden access to. My virtual host is enabled and looks like this: upstream webs { server 10.0.0.30 weight=1; server 10.0.0.31 weight=1; } server { listen 80; server_name www.example.com example.com; access_log /var/log/nginx/access.log; location / { proxy_pass http://webs; include /etc/nginx/proxy.conf; } } and my nginx.conf looks like this: user www-data; worker_processes 4; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; events { worker_connections 1024; # multi_accept on; } http { include /etc/nginx/mime.types; access_log /var/log/nginx/access.log; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; tcp_nodelay on; gzip on; gzip_disable "MSIE [1-6]\.(?!.*SV1)"; include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffers 32 4k; } Can any geniuses out there tell me what I am doing wrong?

  • Determining how all memory is used in Windows Server 2008

    - by Mojah
    Hi, I have a Windows Server 2008 system, which has 12GB of RAM. If I list all processes in the Task Manager, and SUM() the memory of each process (Working Set, Memory (Private Working Set), Commit Size, ...), I never reach more than 4-5GB that should be "in use". However, task manager reports this server has 11GB in use via the "Performance" tab. I'm failing in determining where all that used RAM is going. It doesn't seem to be system cache, but I can not be sure. It might be a memory leak in one of the appliances, but I'm struggling to find out which one. The server's memory keeps filing up, and eventually forces us to reboot the device to clear it. I've been reading up on how RAM assignments work on Windows Server: RAM, Virtual Memory, Pagefile and all that stuff: http://support.microsoft.com/kb/2267427 What's the best way to measure? http://www.zdnet.com/blog/bott/windows-7-memory-usage-whats-the-best-way-to-measure/1786 Configure the file system cache in Windows: http://smallvoid.com/article/winnt-system-cache.html But I fear I'm stuck without ideas at the moment.
