  1. Hi everybody, I am starting to dig into storage network. As a newbie, I have a small question. As we've known, WWN's length is 64 bits. Meanwhile, in Fibre Channel frame, we have only 24-bit addresses. There needs to be some relationship between this 24-bit address and the 64-bit address associated with World Wide Names. When the device with its WWN logs into the switch on a specific port, the switch will assign the port address to that port and the switch will also maintain the correlation between the port address and the WWN address of the device of that port. This function of the switch is implemented by using the Name Server. My question is that: If my storage network does NOT use SAN switch, how can we get the 24-bit address corresponding to the WWN? I hope receiving your reply soon. Thank in advance :-)
  2. Dear all, I have a practical case. My firm has 2 datacenter which are far away about 100km. I wanna build a cluster system (active-active) for these 2 sites in order to realize load balancing & failover idea. Each datacenter has a SAN storage HP P9500. For cluster installation, we need to synchronize data between 2 storages in bidirectional, real-time context. What's the best solution for this? I have ever heared about RecoverPoint technique. Is it possible to apply RecoverPoint to this case and how to do it?
  3. Dear all, When I sent my email from company to partners, they were sometimes marked as spam emails. I wonder how to avoid this problem? What solutions to trust our emails? Thank you very much
  4. I intend to download GeoIp from http://pkgs.org/download/geoip But I don't know which distribution should I choose because there is no download link for Scientific Linux. Can I use the package of other Linux distribution for Scientific Linux? Thank you in advance.
  5. Problem with Static NAT

    Oh, I resolved this problem. Thank you.
  6. About NIST Net installation

    I loaded NIST Net module successfully. This is my solution: NIST Net module was installed successfully. When I read some information from the Internet, some people said we can run NIST Net without RTC module. I am not sure for this. Anyway, we can bypass RTC and use NIST Net. Thank for your support.
  7. I found it. Sorry if disturbing you
  8. Problem with Static NAT

    Dear all, This is my topology: PC ------------ (eth0) LINUX router (eth1)--------Internet Please help me with the configuration of Static NAT. I have a server from local network (IP@: I wanna configure static NAT sothat someone from the Internet can connect to my server. On LINUX router: iptables -t nat -A POSTROUTING -s -o eth1 -j SNAT --to-source <Public IP> iptables -t nat -A PREROUTING -d <Public IP> -i eth1 -j DNAT --to-destination BUT It didn't work. Please point out my fault and how can I resolve it? Thank you very much.
  9. Dear all, I've just install Windows XP on my server - CARRI High Server SR1530AH but it doesn't detect driver for my ethernet card. From the Internet, I tried but I can't see where can I download this driver. I hope you share me the download URL. Thank you very much.
  10. About NIST Net installation

    Today, I tried to test with Scientifc Linux 4.0 (kernel version 2.6.9-5.0.5). With this distribution, I could compile and install NIST Net without errors. It seemed to be better but when I tried to load nistnet modulator by using the command "./Load.Nistnet", it raised an error about RTC Following the instruction from http://www.aimvalley.com/opensource/NistNet.htm?reload_coolmenus, I downloaded the source kernel and recompiled it with CONFIG_RTC=m, use some "make" commands. After restarting Linux, It still remained the same RTC error. I think the current problem now is how to load RTC module succesfully. Could you help in this case. How to load RTC module? Thank a lot for your support.
  11. About NIST Net installation

    I changed my OS. I installed Scientific Linux v5.0 (kernel 2.6.18-8.1.3.el5) on my server and tried to install NIST Net (http://snad.ncsl.nist.gov/nistnet/). First of all, I downloaded NIST Net package and kernel source, used "rpmbuild" and "make oldconfig" to appy the old kernel configuration. These tasks are OK. Then, I extracted NIST Net package into /root/NISTNet/ According to the instruction from this link http://www.aimvalley.com/opensource/NistNet.htm?reload_coolmenus, I downloaded nistnet-3.0a_aimsys.patch file and run it by using command: patch -Np1 -i ../nistnet-3.0a_aimsys.patch After that,. Then, I entered the NIST Net source folder, type. ./configure and make. But the result when I ran the command "make" had some errors althrough I used the patch file. I searched from the Internet, there were some people who also met this error but with another installation. Have you ever experienced this problem? If yes, how can I do? PS: Do I need recompile linux kernel in order to resolve this? Thank you very much. Wish you have a nice weekend
  12. About NIST Net installation

    I have one more small question. As I mentioned, Scientific Linux 5.0 run kernel 2.6.18-8.1.3 Could you tell me where I can download kernel source 2.6.18-8.1.3. I tried but I didn't see it. Thank you.
  13. About NIST Net installation

    I don't understand clearly your idea. What is insmod nistspy? You meaned I needn't type those commands? If I don't insert some modules in the running kernel , are there any issue later on? I have just installed Scientific Linux 5.0 which run kernel 2.6.18. Thank for your help
  14. About NIST Net installation

    Thank for your answer As the website mentioned, NIST Net can run on 2.6.xx kernel (up to around 2.6.11).I think your kernel (2.6.40) is so new. Actually, I haven't installed it on new Linux yet. But I will try.
  15. About NIST Net installation

    Dear all, Currently, I am trying to install NIST Net on Fedora Core 3 (kernel 2.6.9-1.667) following by the installation guide from http://snad.ncsl.nist.gov/nistnet/install.html At the very first step, I don't understand why we should type these following commands: I had installed Fedora Core 3, when I jumped to /usr/src/, I saw some folders without any file in side. I think, for my PC, the kernel was installed in binary. But for the above quote guide, do I need to download kernel source and re-compile it? If I don't follow that instruction, what's problem? Thank you very much
