  • SQL Management Studio external database only

    - by Robuust
    I'm trying to speed up my PC, and I figured out that a full version of SQL Management Studio 2012 is installed including localhost server. I only need to connect to remote hosts, so running a local server by default should be disabled. Is there an easy way to disable certain parts so I can speed up my PC and booting time? Thanks in advance. I really have no clue what processes I can disable without ruining everything.

  • Proper SSH keys location for a system user ?

    - by Thibaut Barrère
    I have a system account with which I run a database (namely mongodb). By default it has no home. Now I'd like to trigger scp commands from that account, with ssh keys authentication to a remote server, to export backups. Should I just create a /home/mongodb and /home/mongodb/.ssh folders manually to store the SSH keys, like the default for regular users ? Is it still considered a system account after that ? Thanks!

  • 20GB+ worth of emails in my /home what is a better solution for that?

    - by Skinkie
    My email storage requirements are outgrowing anything reasonable with respect to local mail storage. As we speak 99% of my home partition is filled with personal mail in Thunderbirds mail dirs. Needless to say, this is just painful, badly searchable and as history has proven me that backups work, but Thunderbird is capable of loosing a lot of mail very easily. Currently I have an remote IMAPS server (Dovecot) running for my daily mail, accessible from anywhere, which from my own practice works efficiently up to about 1000 emails. Then some archive directories should be used to move mail around. I have been looking into DBMail, but I wonder if I make my case worse or better which such solution. None of the supported database employ string deduplication or string compression out of the box, so is this going to help me with 20GB+ mail? What about falling back to a plain old IMAP server? A filesystem like ZFS would support stuff like GZIP transparently, which could help. Could someone share their thoughts? The 20GB mostly consists of mailinglists, and normal mail. Not things like attachments. To add some clarifications; As we speak, my mail is not server side indexed at all - only my new mail arrives at a remote IMAP server. It is all local storage from former POP3 accounts, local mirrored Gmail and IMAP accounts. In my perspective it is not Thunderbird that sucks, its fileformat that sucks. Regarding the 1000 mails. On the road I am using Alpine and MobileMail, quite happy with both of them, but some management is required to actually manage the mail. Sieve helps a lot with that, but browing through 10.000 e-mails is not fun, especially not on a mobile client. I am quite happy with Dovecot, never had any issues with it. I just wonder if this is the way to go. Or if there are any other better solutions. What my question is: what is the best practice solution that allows 20GB+ mails and is -on demand remotely accessible, easy to backup and archive worthy. It doesn't need to be available 24x7. The final approach I took was installing a local IMAP server (Dovecot), configured it for being my archive, using the following guide: http://en.gentoo-wiki.com/wiki/Dovecot/InstallThunderbird

  • How to give Apache access to files in my home directory?

    - by Mark Smith
    I'm a Ubuntu Linux user (Lucid Lynx) who is running Apache. I have a collection of zip files in a folder in my home directory (~/zip_files) which I would like to be able to link to through apache, such that when somebody who visits my website which I'm using Apache to host clicks a link to one of the zip files, he can download it through the web. How can I provide Apache with access to the files and set the permissions? Thanks, I'm new to linux!

  • Exchange 2007 Receive E-Mail for other Domains

    - by Loop
    My organisation has Exchange 2007 e-mail server, and now, we want to host e-mail service for other organisation (neworg.com) I added new Authoritative Active Domain neworg.com, but when adding a new mailbox, there is no option to chose new SMTP domain name neworg.com, and I can't add new user with SMTP domain [email protected]. Probably I misunderstood something while reading posts on Internet, but can someone help please?

  • How do you protect your <appid>.appspot.com domain from DDOS attack?

    - by jacob
    If I want to use CloudFlare to help protect my GAE app via it's custom domain, I still am vulnerable to attacks directly on the .appspot.com domain. How do I mitigate that? I could force redirect appspot.com host requests, such as discussed here: http://stackoverflow.com/questions/1364733/block-requests-from-appspot-com-and-force-custom-domain-in-google-app-engine/ But I would still suffer the load of processing the redirect in my app. Are there any other solutions?

  • VirtualBox Port Forward not working when Guest IP *IS* specified (while doc says opposite)

    - by Patrick
    Trying to port forward from host (Mac OS X) 127.0.0.1:8282 - guest (CentOS)'s 10.10.10.10:8080. Existing port forwards include 127.0.0.1:8181 and 9191 to guest without any IP specified (so whatever it gets through DHCP, as explained in the documentation). Here is how the non-working binding was added: VBoxManage modifyvm "VM name" --natpf1 "rule3,tcp,127.0.0.1,8282,10.10.10.10,8080" Here is how the working ones were added: VBoxManage modifyvm "VM name" --natpf1 "rule1,tcp,127.0.0.1,8181,,80" VBoxManage modifyvm "VM name" --natpf1 "rule2,tcp,127.0.0.1,9191,,9090" And by "non-working", I of course mean not listening (as a prerequisite to forwarding): $ lsof -Pi -n|grep Virtual|grep LISTEN VirtualBo 27050 user 21u IPv4 0x2bbdc68fd363175d 0t0 TCP 127.0.0.1:9191 (LISTEN) VirtualBo 27050 user 22u IPv4 0x2bbdc68fd0e0af75 0t0 TCP 127.0.0.1:8181 (LISTEN) There should be a similar line above but with 127.0.0.1:8282. Just to be clear, this port is listening perfectly fine on the guest itself. And when I remove the guest IP (i.e., clear the 10.10.10.10) the forward works fine, albeit to eth0 (not eth1 where I need it). I can tcpdump and watch the traffic flow back and forth. And yes, I've disabled iptables entirely while testing -- it's not getting blocked anywhere on the guest. As VirtualBox writes in their documentation, you are required to specify the guest IP if it's static (makes sense, no DHCP record it keeps): "If for some reason the guest uses a static assigned IP address not leased from the built-in DHCP server, it is required to specify the guest IP when registering the forwarding rule:". However, doing so (as I need to), seems to break the port forward with nary a report in any log file I can find. (I've reviewed everything in ~/Library/VirtualBox/). Other notes: While I used the above command to add the third rule, I've also verified it showed up correctly in GUI and then removed/re-added from there just to make sure). This forum link -- while very dated -- looks somewhat related in that a port forward to a static IP was not appearing (perhaps they think due to lack of gratuitous arp being sent for host to know IP is there/avail?). Anyway, what gives? Is this still buggy? Any suggestions? If not, easy enough workarounds? What's interesting is that this works perfectly fine on another user's Mac, however he's running a slightly older version (4.3.6 v. 4.3.12).

  • get the list of open applications on windows

    - by noam
    I want to have a script that does the following thing: connect to a remote windows machine get the list of applications that are currently open on the machine, e.g exactly what I would get in the "applications" tab in the task manager, and print it. Is it possible to do that in batch? If not, what other options do I have?

  • Troubleshooting Network Speeds -- The Age Old Inquiry

    - by John K
    I'm looking for help with what I'm sure is an age old question. I've found myself in a situation of yearning to understand network throughput more clearly, but I can't seem to find information that makes it "click" We have a few servers distributed geographically, running various versions of Windows. Assuming we always use one host (a desktop) as the source, when copying data from that host to other servers across the country, we see a high variance in speed. In some cases, we can copy data at 12MB/s consistently, in others, we're seeing 0.8 MB/s. It should be noted, after testing 8 destinations, we always seem to be at either 0.6-0.8MB/s or 11-12 MB/s. In the building we're primarily concerned with, we have an OC-3 connection to our ISP. I know there are a lot of variables at play, but I guess I was hoping the experts here could help answer a few basic questions to help bolster my understanding. 1.) For older machines, running Windows XP, server 2003, etc, with a 100Mbps Ethernet card and 72 ms typical latency, does 0.8 MB/s sound at all reasonable? Or do you think that slow enough to indicate a problem? 2.) The classic "mathematical fastest speed" of "throughput = TCP window / latency," is, in our case, calculated to 0.8 MB/s (64Kb / 72 ms). My understanding is that is an upper bounds; that you would never expect to reach (due to overhead) let alone surpass that speed. In some cases though, we're seeing speeds of 12.3 MB/s. There are Steelhead accelerators scattered around the network, could those account for such a higher transfer rate? 3.) It's been suggested that the use SMB vs. SMB2 could explain the differences in speed. Indeed, as expected, packet captures show both being used depending on the OS versions in play, as we would expect. I understand what determines SMB2 being used or not, but I'm curious to know what kind of performance gain you can expect with SMB2. My problem simply seems to be a lack of experience, and more importantly, perspective, in terms of what are and are not reasonable network speeds. Could anyone help impart come context/perspective?

  • Sendmail yields "user unkown" errors even after (wrongly) setting up a catch-all account

    - by user59240
    I was trying to follow the instructions found here to set up a catch-all account, but still I get the following message for mails sent to non-existent users: The error that the other server returned was: 550 550 5.1.1 [email protected]... User unknown (state 14). Everything else works, though... /etc/mail/local-host-names and /etc/mail/virtusertable were set up as instructed. Any advice? Thanks!

  • Nginx https rewrite turns POST to GET

    - by x7311
    My proxy server runs on ip A and this is how people access my web service. The nginx configuration will redirect to a virtual machine on ip B. For the proxy server on IP A, I have this in my sites-available server { listen 443; ssl on; ssl_certificate nginx.pem; ssl_certificate_key nginx.key; client_max_body_size 200M; server_name localhost 127.0.0.1; server_name_in_redirect off; location / { proxy_pass http://10.10.0.59:80; proxy_redirect http://10.10.0.59:80/ /; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } server { listen 80; rewrite ^(.*) https://$http_host$1 permanent; server_name localhost 127.0.0.1; server_name_in_redirect off; location / { proxy_pass http://10.10.0.59:80; proxy_redirect http://10.10.0.59:80/ /; 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; } } The proxy_redirect was taken from how do I get nginx to forward HTTP POST requests via rewrite? Everything that hits the public IP will hit 443 because of the rewrite. Internally, we are forwarding to 80 on the virtual machine. But when I run a python script such as the one below to test our configuration import requests data = {'username': '....', 'password': '.....'} url = 'http://IP_A/api/service/signup' res = requests.post(url, data=data, verify=False) print res print res.json print res.status_code print res.headers I am getting a 405 Method Not Allowed. In nginx we found that when it hit the internal server, the internal nginx was getting a GET request, even though in the original header we did a POST (this was shown in the Python script). So it seems like rewrite has problem. Any idea how to fix this? When I commented out the rewrite, it hits 80 for sure, and it went through. Since rewrite was able to talk to our internal server, so rewrite itself has no issue. It's just the rewrite dropped POST to GET. Thank you! (This will also be asked on Nginx forum because this is a critical blocker...)

  • can symbolic links be used within App-V packages

    - by user765827
    We use the stats package SPSS through App-V however although it allows use of custom dialogs and macros, these must be placed in a sub folder within the app installation and so this means that users cannot add new macros. Is it possible to have an App-V package include a symbolically linked folder to point to a different place so that this remote folder could be updated easily without necessitating a rebuild and redeployment of the package? Thanks

  • Monitor number of bytes transferred to/from IP address on port.

    - by Mike
    Can anyone recommend a linux command line tool to monitor the number of bytes transferred between the local server and a specified IP address/port. The equivalent tcpdump command would be: tcpdump -s 0 -i any -w mycapture.trc port 80 host google.com which outputs : 46 packets captured 131 packets received by filter 0 packets dropped by kernel I'd like something similar that outputs: 54 bytes out, 176 bytes in I'd like it to work on RHEL and be free/open-source. It would be good if there was an existing tool which I was just missing too!

  • Monitors go to sleep and come back blue

    - by TahoeWolverine
    Recently, my displays have been turning blue when they wake up from sleep. This has hapeened on my Macbook and on my 2nd monitor on my PC (which I use for VM and remote desktop). It's possible that part of it might be my eyes, but seeing the blue monitor next to my other monitor on my PC has convinced me that something is probably out of place. What might that be?

  • Creating a Linux cluster/cloud to act as a server.

    - by Kavon Farvardin
    I have about four or five machines in the Pentium 3-4 era and I'm interested in creating a Linux server comprised of these machines. The server's main purposes would be to host several low-medium traffic websites/services (voice and game), and share terabytes of data on a local network. I could probably throw together one modern computer as a server and call it a day, but I'm interested in using these machines to do it instead. Where would I get started in this cluster/cloud setup?
