• How to retrieve connection details of CheckPoint SSL Network Extender?

  - by amoe

  My workplace uses a Java-based VPN tool named CheckPoint SSL Network Extender. I would like to configure the VPN connection myself using stock OS tools, because I find the applet to be rather unstable. How would I go about getting all of the connection details needed to manually connect to the VPN? My workplace only supports the official client. When I am connected with the Java applet, if I run ipconfig /all I can see that a hidden network connection is created named Check Point Virtual Network Adapter For SSL Network Extender - Packet Scheduler Miniport. I can see the various IP and DNS details there as well. However, because I need to log in to the applet-based tool, I presume I need to export some kind of key in order to use OS tools to configure this. Is this even possible? Answers for any OS are great although I am using Windows XP to test, and also want to use Linux clients.

• linux static ip problem

  - by out_sider

  I have a serve running centOS and I'd like to have the following setup: The server needs to have a static ip and be accessible by name. What I want is independently of the network being able to connect the server to the network and access it by name on Firefox as it will be running a web page. I tried setting the ip manually but while the inet addr is set as I want it the Bcast isn't. And I only can ping the server on the Bcast ip and because it is 192.168.2.255 ssh says it's not valid.

• SMTP 25 blocked externally

  - by Jeff

  not sure how to title this question... we run an exchange server with around 80 internal users, all outgoing mail is relayed off a smart host (ISP smtp server) so nothing is actually sent to the world via our server. i wanted to check the server, locally i can telnet to port 25 with no issues and receive the esmtp service ready reply. whenever i do it from an external address (off our local network) i receive unable to connect error 10060. can this cause problems with SPF records, and reverse DNS ? should my exchange server be able to accept smtp requests, requiring authentication before i am able to send from external addresses? if so how... also the exchange server is behind a NAT (asa) device, more than likely thinking that the nat is not configured to route the smtp 25 request to the exchange server.. thanks

• Changed domain A records for new static ip, but no mail

  - by Tim the Enchanter

  We have recently changed our ISP, I have changed the mail and mailserver DNS A records for our domain name to point to the new external static IP address assigned to the router by the new ISP (the MX record points to mail.<mydomain> as always) but I am not getting any email (though sending email works). Do I just have to wait will the change propagates? I am slightly concerned because I can connect to the web email service made visible through the new router which suggests that the mail.<mydomain> static I.P. address change has happened. Have I missed something?

• How can I access my desktop computer from my Android phone?

  - by Qurben

  Is it possible to access a computer connected to the internet through an Android phone? (the internet goes through the phone by tethering) I want to use ssh to connect to the computer (from a different computer in the same network), but I am not able to access the computer. Is it possible to portforward, use some kind of transparent proxy or to use DMZ? My phone is rooted and I have Cyanogenmod installed and I can use iptables. EDIT: The changed title completely changed the question! My setup is the following: I have an android phone connected to a computer through the usb cable tethering internet from the phone, I wanted to ssh into the computer behind the android phone from another computer in the same network as the android phone. This was not possible, because the android phone creates a separate network for the connected computer, effectively shielding it from any incoming signals. It turned out to be quite simple to fix by just using iptables.

• Opensolaris, ZFS shares

  - by Random

  I've recently updated to OpenSolaris 2010.05 from 2009.06. Its currently set up to share one of the the ZFS zpools to the other machines on my network. However, only a single account is able to access these shares. My other accounts get refused when attempting to connect. File permissions are all correct - When logging into the machine directly with the other logins, I can see, and play with the files and directories as normal - Its just the share that gets refused. The interesting thing is, I could access the shares prior to upgrading. Nothing else was changed other than the straight upgrade. I am pretty sure there is no user specific sharing going on. What could be preventing others from accessing this zpool?

• Why can't I access a webserver through a load balancer on my local network?

  - by Karptonite

  When I try to use curl (or wget, lynx, etc) to connect from a server on our local network to our website, which is on a local server behind a CoyotePoint load balancer, curl fails. Ping does not have this problem. When I curl directly to any of the servers behind that load balancer (from and to the same local network), I also have no problem. It doesn't matter whether the local server I'm curling from is behind the load balancer or not. Does anyone have any idea why I can't access my webserver through the load balancer on my local network?

• How do I set up a proxy server for home with bandwidth control, download limit options?

  - by Quakeboy

  3 room mates share a single 2 Mbps connection. Have a 40GB per month download limit beyond which speed drops to 256Kbps which is annoying. One of the roommates abuses the connection by downloading beyond his quota limit. I have a Netgear WNR1000v2 Wireless router + ADSL Modem to connect to the internet. We all access internet via Wireless router which connects to ADSL Modem. I need a free proxy solution which can help me set 40GB / 3 (13 GB) limit for each person (every person has 2 devices - a PC and a phone with Wifi) Uniform Bandwidth control - when 2 people browse the internet they should get 1 Mbps each, and when 3 people access, they should get 2Mbps divided by 3. After each person crosses their monthly download limit, they should be able to access the internet with 256Kbps speed only or lesser. Can I have a custom firmware on my wireless router do this (or) Do I need a proxy server ? Please point me to any relevant tutorials (for example with Squid).

• OOMK kills mysql and apache when there is still a lot[?] of mem

  - by Flyer

  let me first say that I'm pretty new ti *nix systems and even more to server management. Anyway, I've got a little problem. I got VPS with 1gb mem, system is debian 6. I have few sites running on it, though some load can only be caused by one of them. Recently, OOMK started to kill mysql, causing wp and phpbb giving error that it can't connect to mysql server. Error itself is not good, especially if it happens at night and site becomes unavailable until I wake up and restart mysql. I have probably bad line in my cron which can be cause of it all (again, I'm new to it) */20 * * * * sync; echo 3 > /proc/sys/vm/drop_caches Well, if you need any information, let me know, since I don't really know which information can be useful here. Also, I'd like to know if it's not too bad to have above cron task.

• sendmail error "Relaying denied. Proper authentication required. (state 14)."

  - by renevdkooi

  I am an absolute newB on sendmail, now I installed sendmail, configured it (as far as i know) added localhost-names, added access entries added virtuser entry, opened port 25 in iptables. Now when I connect from another location on the internet, and use telnet server.com 25 and use manual SMTP commands (HELO, MAIL From etc) the mail goes and arrives and gets put to the right user. but When I use another client and it's relayed by (for example google) I get this error back: Relaying denied. Proper authentication required. (state 14). What setting did I forget? Any config files I need to post so you can help me? I use CentOS 5.5 and the latest sendmail rpm

• Copying large file from SD to HDD via USB failing on Ubuntu

  - by Kent Boogaart

  Hi, I'm attempting to copy some large files from my camera (Canon EOS 500D) to my laptop, which is running 64 bit Ubuntu 9.04. I am using USB to connect the two devices. For most files, it is simply a matter of control-C and control-V. I have done this successfully many times with both photos and small movies (eg. 180MB). However, when I attempt to do this with very large files (eg. 3GB), the copy seems to start with a lot of activity both on the camera and laptop, but after 10 minutes or so the camera is automatically unmounted and the copy fails to complete. I have read that this might be due to the device not mounting as a mass storage device, but I cannot see any obvious way for me to change this behavior. Can anyone offer any direction here? I'll get a USB card reader if necessary, but I'd prefer to be able to just plug my camera in. Thanks

• Web-Server directory permissions

  - by MLS

  Hello All, I would like some help understanding web-server directory permissions. Apache, CentOS, PHP, Mysql Example, I have multiple sites in /var/www/html They are in paths like: /var/www/html/www_domainname_com inside each site I might have a path like /lib/mysql/ like PHP connect stuff, database config, etc. What should me permissions be so that someone cannot just browse to that directory? Should I just .htaccess them? I have apache:apache as the owner of all my web directories. Can I prevent someone from crawling certain directories of my web-server? I have a robots.txt, but what is to say the crawler obeys it? So to sum up: 1. What is the best owner/permission set for my sensitive files that the web-server or php or mysql needs, but I dont want people browsing to? Can I prevent straight out crawling of portions?

• Cannot Access Server from External IP (Router)

  - by mindoftea

  We have an Ubuntu 10.04 LAMP server running on site (Apache is on port 80). It is running fine through the LAN, but I cannot access it using its external IP address through the Netopia 3000 Series modem by which it is connected to the internet. I have tried using what Netopia calls "Pinholes" (Port Forwarding) to make the server accessible, but a telnet to the external address just gives me "connect to address x.x.x.x: Operation timed out." I have also tried enabling "Services" and "IP Passthrough" on the router, but it gives the same result as above. How can I enable the server to be accessed through its external IP address? Because it connects fine locally, it would seem to be a problem with the Netopia router. Update: Booting the server in GUI mode instead of text mode solved the problem instantly. Any ideas why?

When i am on R2 and i do enter the ip of the camera then it will work without a problem. However i want to acces the camera from the outside. So in R2 i forwarded a port (done this one other networks without problems). However I can't connect from the outside. Can R1 blocking the port? I cant log in on R1 as long as it is in bridged mode.

• SQL Server 2005 transactional replication break before a configured number of retries

  - by ti2

  We have a SQL Server 2000 Standard database with some tables being replicated (continuous transactional replication) to dozens of SQL Server 2005 Express and MSDE computers. The step 2 of the replication agent job (Run agent) is configured by default to retry every 1 minute for 10 times if some problem ocurr. Because the client machines get shut down at night (they are POS machines), we changed the number of retries to 5760 (4 days), so replication would not be broken at night and would not need to be restarted manually. But the problem is that every other day we have at least one machine with broken replication, with this error: The process could not connect to Subscriber 'POS986'. NOTE: The step was retried the requested number of times (5760) without succeeding. The step failed. It seems that SQL Server is not respecting the number of retries or the interval between retries as we configured. PS: I have restarted the replication job after changing the number of retries from 10 to 5760.

• How can I get Windows 7 to switch audio from a monitor (with built-in speakers) to headphones when t

  - by tnorthcutt

  I have an HP dv5t laptop running Windows 7 64 bit with an Acer H235H monitor connected to it via an HDMI cable. The monitor has built-in speakers, which are a huge improvement over the laptop's speakers. However, when I want to use headphones, right now, I have to connect them to the laptop, then right-click the sound icon in the task bar, select Playback Devices, right click the monitor, and disable it. Is there any way to get Windows 7 to automatically switch the output to the headphones when they're plugged in? That's the behavior that happens without the monitor attached (i.e. it will switch from the laptop speakers to headphones when headphones are plugged in). I have the same issue with a Sony Vaio laptop running Windows 7 64-bit and an identical monitor, for reference.

• Is it possible to access internet on smart-phone through usb (no wi-fi) using Laptop as the modem?

  - by Prahlad Yeri

  One of my relatives has a nokia 5235 smartphone. It is good, but the only limitation is - there is no wifi. bluetooth & usb are the only connectivity options. His laptop has an unlimited broadband but no support for bluetooth, so basically usb is the only method by which he can connect the mobile with laptop. Now, he can do a file-transfer between these two devices, but by any chance, is there a way by which we can share the Laptop's internet connection through usb to the smart-phone? So, bascially its like this: Broadband-modem = Laptop =usb= smart-phone -(want to use internet here) Are there any software or utilities available to achieve this ?

• Is it possible to restrict the connection duration per client on the router (say with OpenWRT)?

  - by static

  How to limit the connection duration per client per period (say, one MAC-address can connect only for 3 hours per week to the network). Where could be defined such a rule? In the firewall? So the rule should define not statically times (this is simple), when the client is allowed to access the network, but the duration of the connection per day/week/month, etc. How/where to implement such rules? Is it possible to do so with OpenWRT/DD-WRT?

• designing solution to dynamically load class

  - by dot

  Background Information I have a web app that allows end users to connect to ssh-enabled devices and manipulate them. Right now, i only support one version of firmware. The logic is something like this: user clicks on a button to run some command on device. web application looks up the class name containing the correct ssh interface for the device, using the device's model name. (because the number of hardware models is so small, i have a list that's hardcoded in my web app) web app creates a new ssh object using the class loaded in step 2. ssh command is run and session closed. command results displayed on web page. This all works fine. Now the end user wants me to be able to support multiple versions of firmware. But the catch is, they don't want to have to document the firmware version anywhere becuase the amount of overhead this will create in maintaining the system database. In other words, I can't look up the firmware version based on the device. The good news is that it sounds like at most, I'll have to support two different versions of firmware per device. One option is to name the the classes like this: deviceX.1.php deviceX.2.php deviceY.1.php deviceY.2.php where "X" and "Y" represent the model names, and 1 and 2 represent the firmware versions. When a user runs a command, I will first try it with one of the class files, if it fails, i can try with the second. I think always try the newer version of firmware first... so let's say in the above example, I would load deviceX.2.php before deviceX.1.php. This will work, but it's not very efficient. But I can't think of another way around this. Any suggestions?

• Secondary fallback/failover network on Cisco ASA

  - by tyranitar

  In my network there is a Cisco ASA 55x0 with "inside" interface (network 192.168.79.0/24) and "outside" interface (network 89.x.x.48/29) There is this nat rule: object network NAToutside nat (inside,outside) dynamic interface and the static route route outside 0.0.0.0 0.0.0.0 89.x.x.49 1 and all ACL rules. Now I have another new outside network by another ISP called "outside2", this network is already natted and the Cisco ASA in in the network 192.168.70.0/24. I would use this network as a fallback one. So I set the nat rule: object network NAToutside2 nat (inside,outside2) dynamic interface and the static route with a different metric route outside2 0.0.0.0 0.0.0.0 192.168.70.1 2 Clearly it doesn't work: when I disconnect the outside ethernet cable no workstation can connect to the Internet throught the outside2 network... What do I need more?
