  • ports only available from the outside network

    - by ChrisJ
    This is a counter-intuitive problem for me. I have a new Win 2003 server on a static IP address w.x.y.z. Tomcat 7, PostgreSQL 9.1, and Subversion are installed. All of it appears to be working fine from the server itself. We can also access the Tomcat manager, web applications, and run "svn ls svn://w.x.y.z/" from outside our network. However, when I try from another machine in the office, phpPgAdmin and svn cannot establish connections with the server. http://w.x.y.z:5432/phppgadmin cannot connect. The svn command from above returns: svn: E730061: Unable to connect to a repository at URL 'svn://w.x.y.z/' svn: E730061: Can't connect to host 'w.x.y.z': No connection could be made because the target machine actively refused it. Tomcat manager and the other web apps we have deployed work fine. Netstat -a from the server shows this: Proto Local Address Foreign Address State TCP SERVERNAME:3690 SERVERNAME:0 LISTENING TCP SERVERNAME:5432 SERVERNAME:0 LISTENING Windows Firewall was off, but just in case I also tried to enable it and open ports 3690 (svn) and 5432 (postgres). No change. I don't have access to the router/switch because it just doesn't work that way in Port-au-Prince and our sysadmin is on R&R. Is there anything that might be causing the problem from the server side?

  • Using GUI ftp on Win7 and Vista without additional software

    - by Stephen Jones
    Goal: provide a 'no-software' method for 'less technical' users to access password protect ftp location from Win7 and Vista (existing approach for WinXP works). 'No software' method to mean without installing additional software (e.g. FileZilla, WinSCP) - the solution is supplied to external non-technical users. WinXP (works): Using Windows Explorer, WinXP supports non-technical ftp access by pasting: ftp://username:[email protected] into the address bar. The remote ftp site's files / directory structure becomes available and can be copied to / from easily (in the style of local file copy / paste) by a 'less technical' user. Win7 / Vista (doesn't work): Pasting the same URL into the Windows Explorer on Win7 or Vista causes an error: An error occurred opening that folder on the FTP server. Make sure you have permission to access that folder. Details: The connection with the server was reset. Notes: a) The same username/password/server typed from the (DOS) command line achieves access to the server, but this is a more 'technical' solution than desired. I am looking for a WinXP equivalent solution. b) Under 'Control Panel' / 'Internet options' / 'Advanced' tab - the boxes for 'Enable FTP folder view' and 'Use Passive FTP' are ticked (enabled) c) Adding an inbound firewall rule for local port 20 (TCP) was attempted with no difference in results (i.e. failure)

  • Using modem for sending voice recording

    - by ircmaxell
    I've got an interesting one for you. I've been going over my server monitoring and notification systems (Nagios based), and realized that if our internet connection goes down, there's no way for it to notify me. I already have a modem listening (Via CentOS 5) on a spare POTS line so that I can dial-in in case our internet goes down. I was wondering if I could come up with a script (Shell, Python, etc) that can dial out and play a recorded message (wave file I'm guessing) when it's picked up. I know Windows supports voice calls over a voice modem, I was wondering if a solution existed for Linux... I know asterisk can probably do it, but isn't that overkill (A full blown VOIP system just for a notification mechanism that will hopefully never be used)? And wouldn't it interfere with the modem's primary function as a backup network interface (PPP spawned via mgetty)? I've done some searching, and haven't really come up with much. I know how to dial out from the command line, but only as a modem (not as voice). Worst case, I could set it up to dial out as a modem, and then just realize that if I get a call with modem sounds from that number that it's the notification... Any insight would be appreciated...

  • WMI Sensors monitoring

    - by DmitrySemenov
    Monitoring tool Paessler stopped to monitor WMI Windows Sensors Paessler is Updated to version 12.4.5.3165. (10/30/2012 1:44:11 PM) Paessler windows sensors (against windows server 2008 R2 web edition) stopped to work (no changes have been made on server that we monitor) with the message Connection could not be established (80070005: Access is denied - Host: 192.168.2.10, User: Administrator, Password: **, Domain: ntlmdomain:) (code: PE015) However if I go to Virtual machine used to run Paessler and the following cscript runs successfully: strComputer = "192.168.2.10" Set objSWbemLocator = CreateObject("WbemScripting.SWbemLocator") Set objSWbemServices = objSWbemLocator.ConnectServer _ (strComputer, "root\cimv2", _ "Administrator", "pass") Set colProcessList = objSWbemServices.ExecQuery( _ "Select * From Win32_Processor") For Each objProcess in colProcessList Wscript.Echo "Process Name: " & objProcess.Name Next I'm getting output C:\>cscript test.vbs Microsoft (R) Windows Script Host Version 5.8 Copyright (C) Microsoft Corporation.

  • SSL wildcard certificates and trailing 'www'

    - by user173326
    I've got a wildcard SSL certificate for *.mydomain.com. I'm using nginx, and redirecting all traffic for http to https, and also rewriting the URLs without a trailing www (if there is one). So it has, 1) http://subdomain.mydomain.com ---> https://subdomain.mydomain.com 2) http://www.subdomain.mydomain.com ---> https://subdomain.mydomain.com 3) https://www.subdomain.mydomain.com ---> https://subdomain.mydomain.com 4) https://subdomain.mydomain.com ---> https://subdomain.mydomain.com However, since my cert is for *.mydomain.com, case 3 gets an SSL error in chrome ('This is probably not the site that you are looking for!'), but if you click through it gets redirected and all is well. I understand why, since the initial connection is for https with a www (2 levels of subdomains), which doesn't match what is on the wildcard certificate. I thought a solution would be to get an additional cert for *.*.mydomain.com to cover www.*.mydomain.com. But it seems like that won't work. I spoke to agents from namecheap and comodo, and both said *.*.mydomain.com was not possible. I also came across this: https://support.quovadisglobal.com/KB/a60/will-ssl-work-with-multilevel-wildcards.aspx Is there a solution to this? To be able to cover www.*.mydomain.com?

  • Installing xampp on system that already have mysql

    - by Charith
    I'm rather new to PHP and xampp. I have a computer that has installed MySQL server and MySQL workbench as I was working with Java and NetBeans. Now I want to use my computer for developing PHP and other web stuff too. I installed xampp successfully. But when I'm trying to access phpMyAdmin, it gives me an error saying mysql server rejected its connection Actually I tried stopping my current MySQL service and installing it again. However xampp have a its own mysql server in its installation path too. I tried configuring config.inc.php to use my existing installation of MySQL which is on a separate path. But I failed. Can anyone please instruct me how to configure this xampp to use my existing MySQL server to do everything and ignore the installed one with itself? I don't want two MySQL services to run on my system and clash in future. I'll be glad if anyone can explain to me what is best to use when you're developing Java, PHP, C and all the stuff on the same machine. P.S.: I have been given a password for my existing MySQL sever (user = root) as we do it usually when installing MySQL alone.

  • How to access Windows Server 2008 R2 file shares from a different subnet

    - by Lloyd Cotten
    We have a couple of severs that used to be Windows Server 2003 that we recently upgraded to Windows Server 2008 R2. A couple of details to set the situation up: We wiped the OS and re-installed. These servers are on one subnet (172.16.x.x) and we are trying to access some file shares on them from another subnet (10.34.x.x). Firewall is disabled on these servers. Trying to access with UNC "\172.16.x.x\sharename" and net use \172.16.x.x However, we're having problems doing this. We are getting "The network path was not found". Here's some of the things we've tried so far and the result: Tried accessing the share from other (non-2008) servers on the same subnet... Success! Ping servers from different subnet... Success! Telnet connection into port 139 from different subnet... Success! Took a scan through Local Security Policies to see if something obvious needed to be enabled / disabled / configured... Fail I'm not sure where to look next. I know that the router between the two subnets is locked down pretty good, but this did work for our 2003 servers. Has anything changed in the way of ports used for UNC / file share access in 2008? Maybe I'm missing some security policy setting? Hoping somebody can take pity on a poor programming guy that can't figure out something really simple. :-) Thanks!

  • If I partition a drive connected via eSata will it show different partitions when connected via USB?

    - by jeffreypriebe
    I have an odd problem with an external drive. I'm formatting it connected to my laptop prior to connecting it to my router. The HDD enclosure has both an eSata and USB connections. Generally, I connect it via eSata to my laptop. I created my partitions and connected it to the router, but I see partition information that is different than what I created. After chasing leads concerning large HDD size, I mindlessly connected the HDD to my laptop with USB. Lo! I see the same partitions as the router. Attached are screenshots using the same program and the HDD in question. The only difference is the connection. For the first, I connected via eSata and hit "refresh" on the partition program. Then, turned off the HDD, disconnected the eSata cable, and connected via USB. Power and refresh. eSata: reports a total HDD size of 2328 GB, with four partitions (the third being 1.96TB) USB: reports a total HDD size of 280 GB, with three partitions (the third being 279 GB) Any idea why this is happening? It looks like it clearly is an issue of the 4K sector size and not playing nice with the USB enclosure. I tried it eSata and USB in Windows and Linux and it appears consistently that eSata is reporting correctly, USB incorrectly.

  • Wireless disconnects at random after upgrade to Ubuntu 10.4

    - by Daniel Elessedil Kjeserud
    After upgrading my home server from Ubuntu 8.10 to 10.4 my wireless seemingly drops out, even though my IRC client keeps it's connection to the servers, so it looks like the machine just stops taking wireless requests. A ping will give a me this Request timeout for icmp_seq 27 ping: sendto: Host is down After a while the machine just starts responding again, without any interaction from me. When the machine comes back, this is what dmesg gives me [ 18.296288] wlan0: direct probe to AP 00:1b:63:22:a4:5f (try 1) [ 18.296350] wlan0: deauthenticating from 00:1b:63:22:a4:5f by local choice (reason=3) [ 18.296440] wlan0: direct probe to AP 00:1b:63:22:a4:5f (try 1) [ 18.298697] wlan0: direct probe responded [ 18.298706] wlan0: authenticate with AP 00:1b:63:22:a4:5f (try 1) [ 18.306836] wlan0: authenticated [ 18.306886] wlan0: associate with AP 00:1b:63:22:a4:5f (try 1) [ 18.309396] wlan0: RX AssocResp from 00:1b:63:22:a4:5f (capab=0x411 status=0 aid=2) [ 18.309402] wlan0: associated [ 18.310187] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready [ 18.447742] apm: BIOS version 1.2 Flags 0x03 (Driver version 1.16ac) [ 18.447748] apm: overridden by ACPI.

  • VSFTPD - FTP over TLS - Upload stops after exactly 82k?

    - by Redsandro
    I installed a VSFTP daemon on a CentOS server, using a RSA certificate for logging in using explicit TLS. Now, I cannot upload more than 82k. With files under that limit, there is no problem. The FTP works like a charm. But as soon as a file reaches 82k with FileZilla (81,952 bytes to be exact), the transfer will stop, and the FTP client hangs until time out is reached. FTP client console: 15:10:21 Command: STOR jquery-1.7.2.min.js 15:10:21 Response: 150 Ok to send data. 15:11:21 Error: Connection timed out 15:11:21 Error: File transfer failed after transferring 82 KB in 60 seconds /var/log/vsftpd.log FTP command: Client "x.x.x.x", "STOR jquery-1.7.2.min.js" FTP response: Client "x.x.x.x", "150 Ok to send data." OK UPLOAD: Client "x.x.x.x", "jquery-1.7.2.min.js", 81952 bytes, 1.32Kbyte/sec FTP response: Client "x.x.x.x", "226 File receive OK." // NOT okay, file is bigger // No mention of error here I cannot find relevant info about this problem, apart from a possible problem with trans_chunk_size (not mentioned in default config), but I tried different sizes and it has no impact on the problem. trans_chunk_size=4096 trans_chunk_size=8192 trans_chunk_size=9999 Ofcourse, after every configuration change, I restarted the server: /etc/init.d/vsftpd restart What else can cause this?

  • Persistent routes for DD-WRT PPTP VPN client

    - by Tim Kemp
    My home network in the USA is behind a Buffalo router (G300NH) running their version of DD-WRT. I use the built-in PPTP VPN client to connect to a VPN provider in the UK. I route certain traffic over the VPN (so it has a UK source address, for various entirely legal reasons) which I achieved by following the instructions in the DD-WRT docs and my VPN provider's own instructions. I placed two commands like this in the firewall script: route add -net xxx.xxx.0.0 netmask 255.255.0.0 dev ppp0 route add -net yyy.yyy.0.0 netmask 255.255.0.0 dev ppp0 I didn't put any of the iptables rules in since it my setup doesn't seem to need them. It works like a charm. Traffic to the xxx subnets goes over the VPN, everything else goes out over my ISPs own pipes. The problem comes when the VPN drops, which it does occasionally. DD-WRT does a fine job of reconnecting it automatically, but the routes are trashed every time that happens. How do I automate the process of re-establishing my routes? I thought about static routes, but the IP address of the VPN connection is dynamically assigned (which is why I'm using dev ppp0). Many thanks, Tim

  • Did a recent WinXP update break CD/DVD read speeds? SP2/SP3

    - by quack quixote
    I have two systems with fresh installations of Windows XP Pro SP3 (SP3 slipstreamed into the installer; fully updated after install). One's a refurbished 2.4GHz Pentium4 system; the other is a new 1.6GHz Atom330 build. Both have brand-new dual-layer CD/DVD burners (one's a LiteOn IDE, the other an LG SATA). Both take a really looooong time to read a single-layer DVD in Windows with Cygwin tools. Specifically, 40 minutes or more. I burn backup data to single-layer DVD+/-R and use MD5 hashes for data verification (made with the standard md5sum tool in Unix or Cygwin). The hashes are burned to disc with the data files, and I use this command to verify: $ cd /path/to/disc/mountpoint ; time md5sum -c < md5.txt Here's how long that takes to run on a full single-layer DVD+/-R disc: Old system (WinXP SP2, 1.8GHz Athlon 2500+, last summer): ~10 minutes Old system (Ubuntu 9.04, 1.8GHz Athlon 2500+): ~10 minutes Old system (Debian 5, dual 550MHz P3): ~10 minutes New Pentium4 system (running Ubuntu 9.04): ~5 minutes New Pentium4 system (running WinXP SP3, file copy from Win Explorer): ~6 minutes New Atom330 system (running WinXP SP3, file copy from Win Explorer): ~6 minutes Now the weird stuff: Old system (WinXP SP2, 1.8GHz Athlon 2500+, today): ~25 minutes New Pentium4 system (running WinXP SP3, read from Cygwin): ~40-50 minutes (?!!) New Atom330 system (running WinXP SP3, read from Cygwin): ~40 minutes (can do it in ~30 minutes ...if i have another program spin up the drive first) Since both systems will copy files in 6 minutes using Windows Explorer, I know it's not a hardware problem. Windows just never spins up the drive during the Cygwin read, so it stays super-slow the whole time. Other programs like EAC and DVD Decrypter seem to spin up the disc just fine during their processing. DMA is enabled on both systems. (Can confirm in Windows' Device Manager on the Atom330, not on the P4.) Nero's DriveSpeed tool doesn't seem to have any effect. Copy times are comparable from commandline with Windows' xcopy. Copying with Cygwin's cp looks more like the problem state -- it will spin up the drive for a short time, never reaches full speed, and lets it spin back down again for most of the copy. What I need is to get full read speeds from Cygwin. Is this a known issue with SP3 or some other recent Windows update? Any other ideas? Update: More testing; Windows will spin up the drive when data is copied with Windows tools, but not when read in place or copied with Cygwin tools. It doesn't make sense to me that Windows spins up the drive for copying, but not for other reads. Might be more of a Cygwin problem? Update 2: GUI activity is sluggish during the problem state -- during the Cygwin verifies, there's a slight but noticable delay when dragging windows or icons around on the desktop, switching windows, Alt-Tabbing through open applications, opening new windows, etc. It reminds me of the delay when opening a Windows Explorer window on My Computer just after inserting a DVD. I've tried updating Cygwin (from 1.5.x to 1.7.x), but no change in the problem behavior. I've also noticed this issue occurs on WinXP SP2, but it's not exactly the same -- some spin-up occurs, so the read happens in ~25-30 minutes instead of 40+. The SP2 system used to run the verifies in ~10 minutes, and when it first changed (not sure exactly when, maybe in late November or early December 2009) I thought it was dying hardware. This is why I suspect an official update of breaking this functionality; this has worked for years on that SP2 box.

Then I change it to "Output: ALSA Audio output" and a Device menu appears. I select the headphones. When I then save the prefs, the audio switch to the headphones! But here's what's weird: I go back to prefs, change it to "Output: Default" and the headphones keep working. Maybe the ALSA option is actually what is being chosen as the "Default" option, but the Device menu (whose selection is still being used) is still set to the headphones. Anyway, now I need to figure out how to make it work as the default for the whole system.

  • Computer makes hissing noise, turns off after few seconds

    - by Kaustubh P
    I have a problem similar to the questions posted here and here. This is my config: Asus M3N78-EM, with AMD Phenom X3 720 2800 Black Edition, 4GB Transcend DDR2 RAM, Nvidia 9400GT. HD is a 160 GB IDE, and a LG IDE DVD-ROM. The power button is a bit off, I have removed the cover of the switch, and the only way it turns on is just giving the "stick" under the cover a gentle press. It turns on sometimes, and at other times, I have to cut-off the power from the PSU, and try again. I will describe my problem in as detail as possible, please bear with me: The problem has started in the last week, a few months after I changed the to the powerswitch arrangement as described above. The PC makes a hissing noise, and I wasn't able to pin-point the noise source, because of the various other fans. At first, removing the HD, rebooting w/o the HD, turning it off, reconnecting and booting made the problem go away. But of late, it doesn't happen. As suggested in the other questions, I tried reducing the load by disconnecting both the IDE drives, and the problem (noise + turn-off) still occurs. I also connected another 80G IDE HD,today morning, adn it still made that noise, and turned off. I also opened up the PSU, but I couldn't see any fault in that, I tried rotating the fan by blowing into the blades, and with my fingers, but the hissing noise didn't come from there. Or maybe the speed wasn't enough to evoke that noise. A few weeks ago: I had cleaned the Cabinet and had repasted the processor and its fan using some thermal paste. Could that be at fault? I also used a vacuum to blow the dust out of the PSU, could the power have been too much, to maybe offset the fan or something? A label on the PSU says it uses a ball-bearing fan. That only leaves me with the Processor fan and the processor itself. I didn't try removing the processor fan and processor from the motherboard, and then turning the PC on, fearing damage. Will doing so cause any damage? What can I do to localize and pin-point the problem? Also, after a few tries, the Computer starts up. Sometimes it turns of within 2 seconds, sometimes after the POST. Once it turned off at the grub. Another time it booted completely and then turned off. The only way to ensure that the PC wont turn off, is if the hissing noise stops. EDIT: I suspect it to be the Processor/Processor fan, owing to the source of noise. All the config, except for the Cabinet, is just over a year old. EDIT2: I also just remembered, that I had set the "On-power resume" to turn on, i.e. If I supply he PC with power, it will turn itself on, w/o me needing to press the switch. I had done that to workaround the faulty power-switch, as noted above. EDIT3: I calculated the power my system needs, from the antec site, and I just arrived at 292W

  • Courier IMAP always disconnects since update

    - by Raffael Luthiger
    Since one of our customers updated their server courier does not handle IMAP connections properly any more. POP3 works without any problems. When I try to test IMAP with telnet then it is always like this: $ telnet domain.com 143 Trying 188.40.46.214... Connected to domain.com. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 UIDPLUS CHILDREN NAMESPACE THREAD=ORDEREDSUBJECT THREAD=REFERENCES SORT QUOTA IDLE ACL ACL2=UNION STARTTLS] Courier-IMAP ready.

There is no other message. And in no other log file I've checked I could find any other related message. The system was updated from Ubuntu 10.10 to 12.04. How could I get more information? Or does anybody have an idea what could go wrong here?

  • How can I debug a port/connectivity issue?

    - by rfw21
    I am running a simple WebSocket server on Amazon EC2 (Fedora Core). I've opened the relevant port using ec2-authorize, and checked that it's opened. Iptables is definitely not running. However I can't connect to the port from outside EC2. I've tried the following (my server is running on port 7000): telnet ec2-public-dns.xx.xx.xx.amazon.com 7000 (from within EC2: connects fine) nmap localhost (output includes line: 7000/tcp open afs3-fileserver) telnet ec2-public-dns.xx.xx.xx.amazon.com 7000 (this time from my local machine: I get "connection refused: Unable to connect to remote host") The strange thing is this: if I start Nginx on port 7000 then it works and I can connect from outside EC2! And the WebSocket server fails on port 80, where Nginx works fine. To me this suggests a problem with the WebSocket server, BUT I can connect to it successfully from within EC2. (And it works fine on a different VPS account). How can I debug this further? If anybody can stop me tearing my hair out, I'd be very grateful indeed :)

  • Motion - takes snapshot without motion detected

    - by Emmanuel Brunet
    I've been installed the standard motion 3.2.12 package on debian 7.5. I would like to get snapshot ONLY when motion is detected, but it still saves a picture every second without any activity in front of the camera. I'm using a TENVIS JPT3815W IP camera motion.conf here is my configuration file setup_mode off target_dir /media/videos/log/webcam netcam_url http://webcam/snapshot.cgi netcam_tolerant_check on netcam_userpass admin:alpha1237 # Output frames at 1 fps when no motion is detected and increase to the # rate given by webcam_maxrate when motion is detected (default: off) webcam_motion off output_all off # detection settings 1-255 default 32 noise_level 50 # Maximum framerate for webcam streams (default: 1) webcam_maxrate 25 pre_capture 0 framerate 25 gap 30 locate on mail [email protected] text_right "FRONT CAMERA %Y/%m/%d - %T" text_double on ffmpeg_cap_new on ffmpeg_cap_motion on ffmpeg_video_codec mpeg4 output_motion off snapshot_interval 0 # Quality of the jpeg (in percent) images produced (default: 50) quality 90 # Restrict webcam connections to localhost only (default: on) webcam_localhost off # Limits the number of images per connection (default: 0 = unlimited) # Number can be defined by multiplying actual webcam rate by desired number of seconds # Actual webcam rate is the smallest of the numbers framerate and webcam_maxrate webcam_limit 0 Issue when I start motion images are stored in /media/videos/log/webcam nearly every second. I hjust want to get images when a motion is detected and the according video clip Any idea where the configuration fails ?

  • Why am I unable to reach local network computers, but able to browse the web?

    - by Igor Zinov'yev
    I have a weird problem. Today after turning my Ubuntu 9.10 PC on I can't connect to my local network, but I can use the Internet. We have a single Windows 2003 server machine that acts as a local main DNS server, DHCP server and a domain controller. Although it seems to give me the local IP address, I can not ping it, as well as any other machine on the net. I have tried all of the below and it didn't help: Rebooting; Reconnecting to the network; Forcing the dhclient to renew the IP address; Deleting and creating new connection profiles; Plugging my machine into another network outlet; Maybe it has something to do with routing, because I have tampered with routing tables the day before, but the tables seem ok to me: $ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 vboxnet0 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0 Our LAN uses a D-Link DI-604 router, and it looks to me as if I am connected to the network outside the router. I can not even access its administration page. Please at least suggest what I can do to solve this. P.S. What seems strangest to me is that I can access the PC in question from outside the network by opening a port on the router. I have managed to ssh to it from outside, but I still can't ping nothing on the inside. P.P.S Today I tried reinstalling network-manager with --purge option, but it did no good. After that I created a new DCHP reservation for my PC in order to change my local IP, but that didn't change anything either. My PC is able to get a DHCP offer, but then it's unable to connect to any local computers. I am desperate.

  • Assistance on setup to Connect an offsite server to the LAN via RRAS VPN - Server 2008 R2

    - by Paul D'Ambra
    I have an office LAN protected using a Zyxel Zywall USG 300. I've set up an L2TP/ipsec VPN on that which accepts connections using a shared secret and I've tested this from multiple clients. I have a server offsite and want to set up RRAS to use a persistent connection to the VPN so that it can carry out network jobs even with no one logged in (I'm using it for Micorosft DPM secondary backup). If I create a vpn as if I were setting up a users laptop it can dial in no problem but if I set up a demand dial interface in RRAS it errors. I enable RRAS ticking only demand dial interface (branch office routing) Select network interfaces, right click and choose new demand dial interface Name the VPN ToCompany Select connect using VPN And then L2TP as the vpn type enter the IP address (double-checked for typos!) select Route IP packets on this interface specify static route to remote network as 10.0.0.0/24 with metric of 1 add dial out credentials (again double checked for typos and confirmed with other vpn connections click finish now I right-click on the new interface and choose properties and then the security tab I change Data encryption to optional select only PAP for Authentication (both as per manufacturer of Zywall) click advanced settings against type of vpn and set shared secret then I select the new interface, right-click and choose connect this dials and then errors with either 720 or 811 as the error codes. However, if I create a VPN by going to Network & Sharing center and setting up as if I was creating a VPN from my laptop to the office (say) it dials successfully so I know the VPN settings are correct and the machine can connect to the VPN. Suggests very strongly the problem is how I'm setting up RRAS. Can anyone help?

  • HTTPS and Certification for dummies

    - by Poxy
    I had never used https on a site and now want to try it. I did some research, but not sure that I understood everything. Answers and corrections are greatly appreciated. Here we go: To use https I need to generate ‘private’ and ‘public’ keys for the web server I use. In my case it’s apache (manual: http://httpd.apache.org/docs/2.0/ssl/ssl_faq.html) Https protocol should be bind to port 443. Q: How to do it? Is it done by default? Where can I check configuration? Aplying https. Q: If I see https in browser does it mean that the data traffic on the page IS encrypted? Any form on the page would submit data via https? Though all the data gonna be encrypted, the browsers would still show ugly red messages. This is just because they do not know anything about my certificate. They have about a hundred certificates pre-installed but mine is not one of them, obviously. But the data IS encrypted by https. If I want browsers to recognize my certificate, I would need to have it signed by one of the certification authorities (ca) that has its certificate pre-installed (e.g. thawte, geotrust, rapidssl etc). UPD: To reed about ssl/tsl: The First Few Milliseconds of an HTTPS Connection, I found it very informative. Examples for PHP (openssl.org) of how to make use of ssl/tsl on the server side are published here.

  • Windows 2012 RDS Temporary profile for Administrator

    - by Fabio
    I've configured a Windows 2012 RDS Farm with two virtual servers (VMWare - each one on a different ESX server). Both servers have Licensing, Web Access, Gateway, Connection Broker and Session Host roles. High Availability is set up and it works fine. Remote Apps are working and even Windows XP clients have access to the web interface. User profile path is \vmfiles1\UserProfileDisks\App\ and almost everyone has full right access to it. The problem I have is that I would like to be able to access both servers at the same time with the Administrator account (console), but each time I try, the second server that I logon to give me access with a temporary profile. I tried to enable/disable multiple sessions per user and forced Admin logoff with the GPO but nothing changed. Another thing is that the server pool is not saved, so each time I restart the RDS server or I logoff from it, I have to add a server in the server manager. Do you have any idea? Sorry if my english is not perfect.
