  • How to configure IIS for SVG and web testing with Visual Studio?

    - by macias
    Let's say I have a simple web page with svg image in it: <img src="foobar.svg" alt="not working" /> If I make this page as static html page and view it directly svg is displayed. If I type the address of this svg -- it is displayed. But when I make this as .aspx page and launch it dynamically from Visual Studio I get alt text. If I type the address of this svg (from localhost, not as a local file) -- browser tries to download it instead of displaying. I already defined mime type in IIS (for entire server -- "image/svg+xml") and restarted IIS. Same effect as before. Question: what should I do more? Update WireShark won't work (it is in documentation), I tried also RawCap, but it cannot trace my connection (odd), luckily Fiddler worked: From client: GET http://127.0.0.1:1731/svg/document_edit.svg HTTP/1.1 Host: 127.0.0.1:1731 User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:10.0.1) Gecko/20100101 Firefox/10.0.1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip, deflate Connection: keep-alive Answer from server: HTTP/1.1 200 OK Server: ASP.NET Development Server/10.0.0.0 Date: Thu, 16 Feb 2012 11:14:38 GMT X-AspNet-Version: 4.0.30319 Cache-Control: private Content-Type: application/octet-stream Content-Length: 87924 Connection: Close <?xml version="1.0" encoding="UTF-8" standalone="no"?> <!-- Created with Inkscape (http://www.inkscape.org/) --> <svg xmlns: *** FIDDLER: RawDisplay truncated at 128 characters.

  • Managing per-user rc.d init scripts

    - by Steve Schnepp
    I want to delegate SysV init scripts to each user. Like the SysV init, each item in ${HOME}/rc.d starting with S will be launched on server start-up with the start argument. The same for the server shut-down with the one starting with K and with the stop argument. I thought about scripting it myself, but maybe there is already some kind of implementation out there1. In summary it would be a script in /etc/init.d/ that iterates through all the users and launches runparts as the user on the relevant scripts. The platform here is a Linux (Debian flavour), but I think the solution would be quite portable among various Unix-like platforms. Update: The point here is for users to be able to create their own init scripts that should be launch on their behalf when the system boots up. As Dan Carley pointed out, the services won't be able to access any system asset (priviledged ports, system logs, ...). 1. This way I don't have to think that much about all the subtle security implications such as script timeouts for example...

  • Vagrant doesn't detect chef-solo unless re-installed

    - by nightowl
    I am using Vagrant to test my Chef recipes in Amazon AWS, and I am encountering an irritating issue: I initially assumed that Vagrant would install chef itself (as it does when using Virtual Box as the provider) but it seems that this needs to be done using the cloud-init script. However, even after I successfully installed the chef gem via cloud-init I was still getting the following error: The chef binary (eitherchef-soloorchef-client) was not found A quick google of this error suggested three probable causes: Chef had failed to install It had installed, but the directory was not in the $PATH environment variable It had installed and in the $PATH but with incorrect permissions I logged in and double checked; chef-solo and chef-client were installed; The path variable for the user, sudo and root all included /usr/local/bin and permissions were all fine. I managed to solve this problem by uninstalling and reinstalling the gem using sudo gem install chef. I don't understand why this should resolve the issue and it is a bit of a problem if I have to ssh into a test box and manually install the gem every time. Does anyone have any suggestions why this might be happening?

  • Exchange Connector Won't Send to External Domains

    - by sisdog
    I'm a developer trying to get my .Net application to send emails out through our Exchange server. I'm not an Exchange expert so I'll qualify that up front!!

  • Configure IIS Web Site for alternate Port and receive Access Permission error

    - by Andrew J. Brehm
    When I configure IIS to run a Web site on Port 1414, I get the following error: --------------------------- Internet Information Services (IIS) Manager --------------------------- The process cannot access the file because it is being used by another process. (Exception from HRESULT: 0x80070020) However, as according to netstat the port is not in use. Completely aside from IIS, I wrote a test program (just to open the port and test it): TcpListener tcpListener; tcpListener = new TcpListener(IPAddress.Any, port); try { tcpListener.Start(); Console.WriteLine("Press \"q\" key to quit."); ConsoleKeyInfo key; do { key = Console.ReadKey(); } while (key.KeyChar != 'q'); } catch (Exception ex) { Console.WriteLine(ex.Message); } tcpListener.Stop(); The result was an exception and the following ex.Message: An attempt was made to access a socket in a way forbidden by its access permissions The port was available but its "access permissions" are not allowing me access. This remains after several restarts. The port is not reserved or in use as far as I know and while IIS says it is in use, netstat and my test program say it is not and my test program receives the error that I am not allowed to access the port. The test program ran elevated. The IIS Site is running MQSeries, but the MQ listener also cannot start on port 1414 because of this issue. A quick search of my registry found nothing interesting for port 1414. What are socket access permissions and how can I correct mine to allow access?

  • OS X borked; need to backup outside of Time Machine

    - by rlbgator
    Quick Background: iMac G5 (the white one; 4 years old?) Running Leopard 10.5.something. Time Machine started failing on me; and every time I touch the Finder, things beachball like crazy. Booting from install disk then using Disk Utility to "Repair Disk" also fails. I'm left with the conclusion that I have a corrupt file somewhere important, that's (i) keeping TM from working and (ii) messing with basic functionality. I am not (yet) savvy enough in OS X to know what logs to look in, or how to decipher them - but 'corrupt file' seems to be the likely case, based on my readings of apple.com forum threads. So I think I need to backup, outside of Time Machine, then install fresh OS X on a new drive (or maybe SpinRite the current drive?). I'm able to put a (non-Time Machine) external USB drive on, so I dragged all 3 Users' folders to that... am I done backing up? Am I going to have a massive Permissions problem, trying to put things back together after a re-install? Thanks for reading.

  • Apache stops responding to http requests -- https continues to work

    - by Apropos
    Okay. Very strange problem that I'm having here. I just recently updated to Apache 2.4.2 from 2.2.17, mostly to try to get name-based SSL VirtualHosts working (although they should have been working on 2.2.17). Server is Win2008 R2 (so x64 by definition) running with PHP 5.4.3 and MySQL 5.1.40 (outdated, I know). When I launch the server, it initially works fine. Responds to all requests, VirtualHosts all in order. However, after an uncertain amount of time (appears to only take a few minutes for the most part, but sometimes takes hours), it stops responding to regular HTTP requests (on any VirtualHost). HTTPS continues to work. No errors in the log, and nothing in the access logs when I attempt to connect. I'm having a hard time finding the source of this error given its intermittent nature. When removing all SSL-based VirtualHosts, it seemingly increased stability (still responding to HTTP requests twelve hours later). This could be mere coincidence, though. Entirety of SSL VirtualHost is as follows, should there happen to be a problem with it. <VirtualHost *:443> DocumentRoot "C:\Server\www\virtualhosts\mysite.net" ErrorLog logs/ssl.mysite.net-error_log CustomLog logs/ssl.mysite.net-access_log common env=!dontlog SSLEngine on SSLProtocol all -SSLv2 SSLCipherSuite ALL:!ADH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:+MEDIUM SSLCertificateFile C:/Server/bin/apache/apache2.4.2/conf/ssl/server.crt SSLCertificateKeyFile C:/Server/bin/apache/apache2.4.2/conf/ssl/server.key SSLCertificateChainFile C:/Server/bin/apache/Apache2.4.2/conf/ssl/sub.class1.server.ca.pem SSLCACertificateFile C:/Server/bin/apache/Apache2.4.2/conf/ssl/ca.pem </VirtualHost> Any ideas what I'm missing?

  • Fixed Resource Monitor Graph Scale in Windows Server 2008 R2

    - by Clever Human
    In Windows Server 2008 R2's Resource Monitor, is there a way to set the scale of the various graphs to be constant values instead of variable based on data? It seems to me that the utility of a graph is to get a quick overview glance at the values those graphs are showing. So if I look at the CPU graph and the line is up near the top, I can know immediately that something is using all my CPU and go investigate what. I don't really care if the CPU is jumping between .01% and 2%. Or if the network usage monitor is up near the top, I will know that all my bandwidth is being used up, and go figure out what. But the way things are now, the graphs are meaningless because the scales constantly shift. If you look at the network usage graph in one second it might have a scale out of 100kbps, and the next second have a scale based on 1mbps! So... is there a registry key or something that will peg the scale of these graphs to logical maximums?

  • Restricting Access to Application(s) on Point of Sale system

    - by BSchlinker
    I have a customer with two point of sale systems, a few workstations and a Windows 2003 SBS Server. The point of sale systems are typically running QuickBooks Point of Sale and are logged in with a user who has restricted permissions / access (via Group Policy). Occasionally, one of the managers needs to be able to run a few additional applications -- including some accounting software. I have created an additional user for this manager, allowing them to login and access the accounting software. The problem is, it can be problematic to switch users on the system, as QuickBooks takes a few minutes to close (on POSUser) and then reopen (on ManagerUser). If customers are waiting, this slows things down drastically. Since the accounting software is stored on a network drive, it would be easiest if the manager could simply double click something, authenticate against the network drive / domain controller and then the program would launch. When they close the program, the session to the network drive would be lost and the program would no longer be accessible. Is there any easy way to do this? Both users are on a domain and the system is Windows 7. I just don't want to require the user to switch back and forth. In a worst case scenario, they forget to switch back and leave the accounting software wide open.

  • Completely remove and freshly install MySql on XP?

    - by Corey Ogburn
    I have read this question and have not found it as a solution and I have even attempted much more. I've uninstalled MySql 5.5.18 and deleted: C:\Program Files\MySql C:\Documents and Settings\All Users\Application Data\MySql After uninstalling, I restart the computer. When I reinstall, in the MySql Server Instance Configuration Wizard I leave everything to their defaults except: I add a firewall exception I check Launch MySQL Server Automatically I check Include BIN directory in windows path Enable root access from remote machines (I'll lock that down later, just debugging for now, I have also tried installing without this option to no avail) I've tried Typical and Complete while installing, as well as with and without strict mode. No combination shows a difference. After all this, it cannot Apply Security Settings and I get a 10061 error (it also said error number 2003) and this article didn't help. I've tried everything I can to completely uninstall and successfully reinstall so I can start from scratch. I've uninstalled and reinstalled about a dozen times with minor changes (including turning off the firewall at times), each time deleting the above folders and any proper registry entries with no success. Note by success, applying security settings and a working remote connection. I can connect locally every time, but it's remotely that counts. I have tried to look for exterior problems such as port forwarding in the router and (even though the installer should add it) I do double check the firewall settings, which have always allowed the default port. I'm out of ideas.

  • Issues with VPN functionality

    - by Xorandor
    I've been working on setting up VPN connectivity to our office location. We bought a Cisco WRV210 which have a builtin VPN server. Cisco has some software QuickVPN, which is not as quick and easy as I had thought. I've had mixed experiences on different machines with connecting. Instead I configured an IPSec VPN tunnel following a guide from TheGreenBow here http://www.thegreenbow.com/doc/tgbvpn_cg_linksys_wrv200_en.pdf I followed their instructions and tried out an evaluation of their software, and VPN connection should be working ok. I'm able to do RDP to a machine on the network (using IP address, not machine name) and ping the router etc. What I'm trying to solve are two things: It's not like I'm "really" on the network. Or at least I'm restricted to some degree when going through the VPN. I can't access a machine on the network using machine name, only IP. I can't ping a machine, but the router just fine. Could this be that something is not set up properly? If so, I can ofcourse supply additional information. Second, when I log onto the VPN, I would really like my outgoing connection to go through the internet connection of the remote location. Basically if I connect to the VPN I want my outgoing IP to be that of the remote location's (needed for some IP resctrictions on some of our servers). At a previous work location it worked like this when we connected to our office VPN over PPTP and the builtin windows VPN client. I'm not a huge expert on the topic, so any hints will be appreciated.

  • Are there any custom keyboard available for laptops

    - by Ahe
    My work laptop is a HP elitebook 8560w which I mainly use for programming. Usually I have a external keyboard but recently I have been working out of office and therefore have been using the laptops own keyboard. One thing has really started to bug me. The keyboard layout of this 15.6" laptop contains numpad but the arrow keys are really bad (too small). Also when programming, I really miss a standard inverted T-arrow keys and the home/end/PgUp/PgDn buttons. Then it occurred to me; I would rather give up a numpad than a standard arrow keys. (The keyboard real estate in 15.6" laptop would allow this, and I really have to agree with Jeff Atwood here http://www.codinghorror.com/blog/2009/02/have-keyboard-will-program.html) Which brings me to my question. Do any laptop manufacturers make custom keyboards for their laptops or is there some third party manufacturer who could supply these kind of special keyboards? Quick googling on this doesn't give any meaningful results. Looks like that I have to carry an external keyboard with me if someone here can't give any pointers.

  • Network latency and speed of light

    - by James
    This was kinda of covered by the following Is minimum latency fixed by the speed of light? , but i would like to add the follow up a bit. The scenario is as follows; we have two opposing sites one on the West Coast of the US and one in Ireland. The customer is in central Europe, and has requested a latency test. Ireland gives responses of ~65-70ms. However the West Coast guys claim to be faster with a response of 60ms. Now a quick check says that light in fiber would take about 42ms to make the trip to the States and 8.5ms to Ireland. So obviously this is a single hop and does not include routers, switches, firewalls, protocol overhead etc. Would I be right to call BS on their figures? As a final note I tested a ping to Google IP address that was allegedly on the west coast from a site that covered a similar distance and was amazed to get a response time of 20ms. Suggesting ICMP packets that travel twice the speed of light. So A) what am I missing B) Am I right to suspect shenanigans? UPDATE: Guys thanks so far for your help and I have been reading various previous questions on this. About 5 years I had an issue where the hop from the UK to Ireland added 10ms of latency no matter what we did. In the end I moved the servers; So imagine my surprise when I have guys that claim they are 5ms faster with a transatlantic trip. So again should I call BS? Oh and assume both sites are normal mortals that don't have access to Google magical routing, warp dives or flux capacitors. :)

  • Bypassing SQUID on freebsd with PF

    - by epema
    I have PF+SQUID31 on FREEBSD-9.0, and I want to have some hosts(aka goodguys) to bypass the proxy, so that torrents are not logged. Also, I am not sure about transparent. It means that I dont have to configure proxy settings on the client side right? I have tried doing a redirect no rdr on $int_if inet proto {tcp,udp} from 192.168.1.233/32 to any However, no luck :( Here is a quick look of my conf files: SQUID /usr/local/etc/squid/squid.conf http_port 192.168.1.1:8080 transparent RC /etc/rc.conf: gateway_enable="YES" pf_enable="YES" pf_rules="/usr/local/etc/pf.conf" pflog_enable="YES" squid_enable="YES" I have squid31 installed from ports with SQUID_PF "Enable transparent proxying with PF" on PF /usr/loca/etc/pf.conf: int_if="re0" ext_if="bge0" localnet="{ 192.168.1.0/24 }" table <goodguys> const { "192.168.1.219", "192.168.1.233" } set block-policy drop set skip on lo0 scrub in all fragment reassemble scrub out all random-id max-mss 1440 block in on $ext_if pass out on $ext_if keep state block in on $int_if pass in on $int_if inet proto tcp from $int_if:network to $int_if port 8080 keep state pass in on $int_if inet proto udp from $int_if:network to $int_if port 21 keep state pass in on $int_if inet proto udp from $int_if:network to $int_if port 22 keep state pass in on $int_if inet proto udp from $int_if:network to $int_if port 53 keep state pass in on $int_if inet proto tcp from $int_if:network to any port { smtp, pop3 } keep state pass in on $int_if inet proto icmp from $int_if:network to $int_if keep state pass out on $int_if keep state What lines should I add in conf files? I am assuming that the problem is on the firewall(pf).

  • How can I make XAnalogTV fill my screen?

    - by Breakthrough
    I recently installed xscreensaver, as well as the additional/extra screensavers. Many of the OpenGL ones function correctly, going fullscreen as expected. However, for some reason, the XAnalogTV screensaver leaves two "blank" spots on the edges of my screen. If I manually launch XAnalogTV, it displays a window, which it fills correctly. When I maximize the window, the same effect occurs: the window maximizes, but the two edges of the screen are literally "transparent". This effect also occurs when the screensaver is set to fullscreen. For these reasons, I believe the problem may be related to the aspect ratio of the screen. The edges of the screen are literally "ignored", with nothing being drawn there. Specifically, note the transition between the maximized and full-screen screenshots (with the un-drawn whitespace shrinking as the vertical height has been increased). For reference, I am running Xubuntu 12.04 on a Dell Vostro 1520 (Intel P8600, Nvidia 9300M) with a 1440 x 900 display (16:10). I have also set the GetViewPortIsFullOfLies preference to true. Is there any way to force XAnalogTV to fill my entire screen? Relevant screenshots (windowed, maximized, and full-screen, respectively):

  • Piecing together low-powered hardware for an RS-232 terminal server

    - by Fred
    I'm working on reconstructing my Cisco lab for training/educational purposes and I found that the actual terminal server I have is dead. I have a couple of 8-port PCI serial cards which would be more than ample for my lab, but I don't want to leave my personal computer running to be able to access the console ports. Ideally I would access the terminal server remotely, either by SSH/RDP to the box (depending on what OS I go with) or by installing a software package that allows me to telnet directly to a serial port. I know I've found a program that does this under Linux in the past but its name escapes me at the moment. I'm thinking about scavenging for some old hardware, on eBay or something, to put together a low-powered PC. Needs to be something that: Has Low-power consumption Has at least 2 PCI slots (though I certainly wouldn't complain about having more) Has onboard Ethernet (or, if not, another PCI or ISA slot (not shared)) Can be headless once an OS installed (probably Linux) I'm currently leaning towards an old fashioned Pentium (sub-133MHz era) but I am wondering if anybody else knows of another platform/mobo that would suit these needs. Alternatively, I've been considering buying a Raspberry Pi and a big USB hub along with a bunch of USB-Serial adapters but this sounds like it'd get messy quick with cables and adapters all over the place, and I may not even have the same ttyS#'s between boots.

  • Homebrew large data cluster access for 2 user levels?

    - by Yegor
    The title probably makes little sense, so here is an example. I have a file hosting site, that serves a large amount of semi-randomly accessed files. The setup is as follows: High horsepower front-end +DB server that also does encoding for files that need encoding Fresh file server, which stores newly uploaded content, thats probably (and usually) rapidly accessible, which has 500GB of raided SSD storage, that can push over 3GBit of traffic. 3 cheap node servers, containing 2 x 750GB SATA drives in raid1, where files older than 2 weeks are archived, from the SSD server (mentioned above). Files on each server are accessed via subdomains (via modsec) in a straight forward fashion (server1.domain.com, server2.domain.com, etc) Where I have the problem is this. I introduced a "premium" service where people pay a small fee every month, and get ad-free, quick accesses to stuff on the site. Once they are logged in, they access same files via premium.server1.domain.com via a different modsec script, with a different pass phrase. That all works fine and dandy.... except the cheap node servers are all IO bound, so accessing the files on them via a different, unsaturated network makes no difference, since it cannot read off the drive fast enough. What would be a good way to make files on the site be accessible via 2 different network routes, 1 of which will be saturated (the "free network") while all other files are on an un-saturated "premium" network?

  • .tex file remains in use by process when batch file is triggered by .Rnw Sweave processing.

    - by drknexus
    This is a pretty specialized question. I'm using the Eclipse IDE in a Windows XP environment with the StatET plug-in so I can write R code as an R/Sweave document. This produces a .tex file that is then post processed by pdflatex.exe. When I create the file as normal everything works great (except maybe my file named russfnc2.Rnw seems to result in russfnc.pdf even though pdflatex.exe on the console window correctly says that the output is being writen to russfnc2.pdf). The big problem is when I trigger a batch file from within my Rnw code. My goal here is to spawn a side process that waits for the PDF to be made and uploads it to the server. So the Rnw contains: if(file.exists("rsp.finalize.bat")) {system("rsp.finalize.bat",wait=FALSE,invisible=FALSE)} The batch file calls Rterm.exe to run a script: setwd("C:/theprojectdirectory") while(!file.exists("russfnc.pdf")) { Sys.sleep(1) } Sys.sleep(60) At the end of that script, I use a shell call to launch psftp.exe and upload the files. All of this works fine, when I use my Eclipse profile to trigger Sweave... that is unless I have that batch file at the end of the .Rnw. When it is located there, I get the error message pdflatex.exe: Permission denied: c:\thepath\thetexfile.tex. After that, the .tex file (as far as XP is concerned) is in use by another process and I have to reboot in order to delete it (and, of course, the pdf is not made). If I manually trigger the batch file after pdflatex.exe has done its things, everything works fine. How can I make this work correctly using the tools I'm familiar with vis., R and Dos-style batch files? I'm not sure if this is a SuperUser question or a StackOverflow question, so I'm starting here.

  • RAID6 mdraid -> LVM -> EXT4 root with GRUB2?

    - by Rotonen
    2012-03-31 Debian Wheezy daily build in VirtualBox 4.1.2, 6 disk devices. My steps to reproduce so far: Setup one partition, using the entire disk, as a physical volume for RAID, per disk Setup a single RAID6 mdraid array out of all of those Use the resulting md0 as the only physical volume for the volume group Setup your logical volumes, filesystems and mount points as you wish Install your system Both / and /boot will be in this stack. I've chosen EXT4 as my filesystem for this setup. I can get as far as GRUB2 rescue console, which can see the mdraid, the volume group and the LVM logical volumes (all named appropriately on all levels) on it, but I cannot ls the filesystem contents of any of those and I cannot boot from them. As far as I can see from the documentation the version of GRUB2 shipped there should handle all of this gracefully. http://packages.debian.org/wheezy/grub-pc (1.99-17 at the time of writing.) It is loading the ext2, raid, raid6rec, dosmbr (this one is in the list of modules once per disk) and lvm modules according to the generated grub.cfg file. Also it is defining the list of modules to be loaded twice in the generated grub.cfg file and according to quick Googling around this seems to be the norm and OK for GRUB2. How to get further by getting GRUB2 to actually be able to read the content of the filesystems and boot the system? What am I wrong about in my assumptions of functionality here? EDIT (2012-04-01) My generated grub.cfg: http://pastie.org/3708436 It seems it first makes my /usr logical volume the root and that might be source of the failure? A grub-mkconfig bug? Or is it supposed to get access to stuff from /usr before / and /boot? /boot is on / for me - no separate boot logical volume.

  • Monitoring memcached with plink

    - by kojiro
    I need a telnet client that can take commands from a file or stdin so I can do some quick-and-dirty automatic monitoring of memcached. I thought plink would be good for this, but it seems to be doing something beyond what I need: If I telnet into localhost 11211 and write stats, I get the memcached stats, like so: $ telnet localhost 11211 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. stats STAT pid 25099 STAT uptime 91182 STAT time 1349191864 STAT version 1.4.5 STAT pointer_size 64 STAT rusage_user 3.570000 STAT rusage_system 2.740000 STAT curr_connections 5 STAT total_connections 23 STAT connection_structures 11 STAT cmd_get 0 STAT cmd_set 0 STAT cmd_flush 0 STAT get_hits 0 STAT get_misses 0 STAT delete_misses 0 STAT delete_hits 0 STAT incr_misses 0 STAT incr_hits 0 STAT decr_misses 0 STAT decr_hits 0 STAT cas_misses 0 STAT cas_hits 0 STAT cas_badval 0 STAT auth_cmds 0 STAT auth_errors 0 STAT bytes_read 82184 STAT bytes_written 7210 STAT limit_maxbytes 67108864 STAT accepting_conns 1 STAT listen_disabled_num 0 STAT threads 4 STAT conn_yields 0 STAT bytes 0 STAT curr_items 0 STAT total_items 0 STAT evictions 0 STAT reclaimed 0 END But with plink, I get an odd error. I'm using this command: watch -n 30 plink -v -telnet -P 11211 127.0.0.1 <<< $'\nstats' The first time through I get: Looking up host "127.0.0.1" Connecting to 127.0.0.1 port 11211 client: WILL NAWS client: WILL TSPEED client: WILL TTYPE client: WILL NEW_ENVIRON client: DO ECHO client: WILL SGA client: DO SGA ERROR STAT pid 25099 STAT uptime 91245 STAT time 1349191927 STAT version 1.4.5 … END But when watch repeats the command I just get: Looking up host "127.0.0.1" Connecting to 127.0.0.1 port 11211 client: WILL NAWS client: WILL TSPEED client: WILL TTYPE client: WILL NEW_ENVIRON client: DO ECHO client: WILL SGA client: DO SGA Failed to connect to 127.0.0.1: Connection reset by peer Connection reset by peer FATAL ERROR: Connection reset by peer What is plink doing here that is different from normal telnet? How should I be going about this? (I'm not married to plink, but I need a way to continuously send simple telnet commands to memcached without writing a full-fledged perl script.)
