  • Logging communication between two VMs

    - by sYnfo
    Hi, I'm trying to set up "malware lab" described in this paper. So far, I've set up Windows guest system, adding one Host-only Network adapter, and setting this (sorry if the names aren't exactely correct, I don't have an english language version): - IP Address - 10.0.0.3 - Subnet mask - 255.255.255.0 - Default gateway - not set - Preferred DNS - 10.0.0.4 - Alternate DNS - not set And a Linux guest system - Ubuntu 9.04 - with two Network adapters - Bridged (eth0) and Host-only (eth1), and setting eth1 IP Address to 10.0.0.4, leaving the eth0 to be set by DHCP. Then, I have configured iptables as described in the paper, ie.: iptables -F -t nat iptables -F -t mangle iptables -t mangle -P PREROUTING ACCEPT iptables -t mangle -P OUTPUT ACCEPT iptables -t nat -P PREROUTING ACCEPT iptables -t nat -P POSTROUTING ACCEPT iptables -t nat -P OUTPUT ACCEPT iptables -t mangle -A PREROUTING -i eth0 -j ACCEPT iptables -t mangle -A PREROUTING -p udp -i eth1 -d 10.0.0.3 --dport 53 -j ACCEPT iptables -t mangle -A PREROUTING -p tcp -i eth1 --dport 80 -j ACCEPT iptables -t mangle -A PREROUTING -p tcp -i eth1 -d 10.0.0.3 --dport 6000:7000 -j ACCEPT iptables -t mangle -A PREROUTING -i eth1 -j ULOG iptables -t mangle -A PREROUTING -i eth1 -j DROP Now, when I try to ping the windows system from within the Linux system, it does not reply, I guess thats perfectly normal, because iptables is blocking ping responce. Same when I try to ping the Linux system from within the Windows. But when I try to access any web page from within the Windows system, I would expect that this action should get logged by iptables. But thing is, I don't see any of that kind of lines in log file (If I am looking in the right place, that is. :) It is at /var/log/messages, isn't it?). So, what do you think might be the problem here? I should note, that this is the first time I'm using linux, so don't expect ANY working knowledge of Linux at all... :) Also, since english is not my mother tongue, feel free to point out any gramatical mistakes... :) Thanks for any advice.

  • Why does pulling the power cord then pressing the power button fix a non-booting PC?

    - by sidewaysmilk
    I've been working at this institution for about 6 years. One thing thing that I've always found curious is that sometimes—especially after a power outage—we find a PC that won't boot when the power button is pressed. Usually, the fans will spin up, but it won't POST. Our solution is to pull the power cord, press the power button with the computer unplugged, then plug it in and turn it on. It seems more common with Gateway brand PCs than the Dells or HPs that we have around. Does anybody know what pressing the power button does when the computer is unplugged? I have some vague notion that closing the power button circuit allows some capacitors to discharge or something, but I'd like a firmer answer to offer my users when they ask me what I'm doing. My best guess as to why fans can spin but it can't POST is that the BIOS is in some non-functional state. I don't know how BIOS stores state, but my best guess is that there is some residual garbage in its registers or something, like the stack pointer isn't starting at 0 maybe?

  • How can I determine the IP addresses allocated by DHCP on a router that I'm connected to?

    - by user234831
    This "router" is not a typical situation. I'm using my phone as a hotspot and can only configure a select number of DHCP options. I can manage the limit on how many devices/clients can use my phone as a hotspot. I have to select from a radio-button list with the options: 2,3,4,5, or 8 I can specify the DHCP starting IP address. In this case, it begins at 192.168.6.106 When I'm connected via WIFI to my phone, an ipconfig /all command shows me that the default gateway is 192.168.6.1 and my IPv4 address is 192.168.1.148. I have the luxury of connecting another device to the phone and that device was assigned 192.168.1.121. I've tried connecting to 192.168.6.1, hoping for some sort of router setup page that I'm used to seeing, but there is no such thing or maybe it's just a matter of incompatable operating systems. In summary, the "router" (phone) has an IP address of 192.168.6.1 and a DHCP server that begins at 192.168.6.106 and allows up to 8 connections. Normally, I would assume a range of 192.168.6.106 - 192.168.6.113, but connected clients are showing otherwise. How can I figure out which IP addresses are set aside by DHCP for clients?

  • Different subnets routing with just one layer 3 switch

    - by GustavoFSx
    Our current network looks like this: Location 1: 2 Layer 2 switches | subnet 192.168.1.0/24 | Firewall for our VPN Location 2: 1 Layer 2 switch | subnet 192.168.3.0/24 | Firewall for our VPN Location 3: 1 Layer 2 switch | subnet 192.168.5.0/24 | Firewall for our VPN We just got a direct fiber connection between location 1 and 2, we also got a new HP V1910 24G layer 3 switch. I tried to follow the instructions on this site, but I can't get it to work. I think our network should look like this: Location 1: HP Switch FIBER to L2 | subnet 192.168.1.0/24 | Firewall for our VPN Location 2: 1 Layer 2 switch | subnet 192.168.3.0/24 | FIBER to L1 Location 3: 1 Layer 2 switch | subnet 192.168.5.0/24 | Firewall for our VPN So, how can I get routing working on our location 2? It's old gateway was a firewall device on ip 192.168.3.1. I'm thinking on creating a VLAN Interface on 192.168.3.1 on the switch for the Location 2. But how will I handle that on the HP switch that has a direct fiber connection with that switch? Please help, I'm not very good with networking.

  • Receiving and processing SMS messages through a script?

    - by ShankarG
    I am attempting to setup a system to receive and process SMS messages automatically. The system is intended for use in a context (an unfunded migrant workers' union in India) where both finances and sysadmin skills are extremely constrained (I would be the only person, in the near future, who would be administering the system). The intention is to make some functions - registration of members, generation of ID cards, communication of alerts and other information - easier. However, for receiving and sending SMS, I have not been able to find any email to SMS or other kind of gateway that functions in India. Perhaps there is one (edit: apparently Clickatell does have an India service, but the prices appear astronomical). If not, can one rely on a USB mobile modem (such as those provided by many mobile providers in India)? It seems like, with utilities such as gammu or bitpim, SMS operations on such a modem could be scripted. Is this actually feasible, though? Thanks in advance for your thoughts and suggestions. edit: Original first question removed since the two questions had little to do with each other. The original first question has been asked separately here

  • Designing a persistent asynchronous TCP protocol

    - by dogglebones
    I have got a collection of web sites that need to send time-sensitive messages to host machines all over my metro area, each on its own generally dynamic IP. Until now, I have been doing this the way of the script kiddie: Each host machine runs an (s)FTP server, or an HTTP(s) server, and correspondingly has a certain port opened up by its gateway. Each host machine runs a program that watches a certain folder and automatically opens or prints or exec()s when a new file of a given extension shows up. Dynamic IP addresses are accommodated using a dynamic DNS service. Each web site does cURL or fsockopen or whatever and communicates directly with its recipient as-needed. This approach has been suprisingly reliable, however obvious issues have come up and the situation needs to be addressed. As stated, these messages are time-sensitive and failures need to be detected within minutes of submission by end-users. What I'm doing is building a messaging protocol. It will run on a machine and connection in my control. As far as the service is concerned, there is no distinction between web site and host machine -- there is only one device sending a message to another device. So that's where I'm at right now. I've got a skeleton server and a skeleton client. They can negotiate high-quality authentication and encryption. The (TCP) connection is persistent and asynchronous, and can handle delimited (i.e., read until \r\n or whatever) as well as length-prefixed (i.e., read exactly n bytes) messages. Unless somebody gives me a better idea, I think I'll handle messages as byte arrays. So I'm looking for suggestions on how to model the protocol itself -- at the application level. I'll mostly be transferring XML and DLM type files, as well as control messages for things like "handshake" and "is so-and-so online?" and so forth. Is there anything really stupid in my train of thought? Or anything I should read about before I get started? Stuff like that -- please and thanks.

  • Trying to diagnose network problem: ping 127.0.0.1 (or any address) results in error code 1

    - by Mnebuerquo
    NIC seems to be working, as windows detects the hardware and has a driver and reports success. DHCP seems to have gotten an ip address, 192.168.1.101. I released and renewed it and it seemed to work normally. I tried ping 127.0.0.1 as first step of testing network configuration. Pinging 127.0.0.1 with 32 bytes of data: PING: transmit failed, error code 1. I read somewhere that net helpmsg [error code] would give a human readable name for the error code. net helpmsg 1 says "Incorrect function" I've tried disabling the firewall and antivirus in McAfee SecurityCenter and I still get the same error. Could the firewall/antivirus be breaking it even if disabled? Broadcom Advanced Control Suite 2 is installed, and its network test passes all tests, including ping 192.168.1.1 which is the default gateway. If I try ping 192.168.1.1 from the command prompt I get the error code 1 again. So does anyone have any theories that would explain this problem? Other tests I should try? Thanks!

  • How can I ensure that my static ip address is read from /etc/network/interfaces rather than dhcp?

    - by jonderry
    This is a follow up to the following question. I'm trying to set a static IP by changing /etc/network/interfaces to the following: # interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.2.133 netmask 255.255.255.0 gateway 192.168.2.1 dns-nameservers 8.8.8.8 and then running /sbin/ifdown eth0; /sbin/ifup eth0. However, the change in IP address doesn't appear to take effect without editing /etc/dhcp/dhclient.conf and commenting out the following before running ifdown; ifup: request subnet-mask, broadcast-address, time-offset, routers, domain-name, domain-name-servers, domain-search, host-name, dhcp6.name-servers, dhcp6.domain-search, netbios-name-servers, netbios-scope, interface-mtu, rfc3442-classless-static-routes, ntp-servers, dhcp6.fqdn, dhcp6.sntp-servers; Strangely, after commenting out this line, running ifdown; ifup works, but when I uncomment it, the behavior does not revert to the previous behavior of ignoring changes to my settings in /etc/network/interfaces (this doesn't seem like a problem, but I really need to be able to repeat this problem so that I can be confident that my solution is robust) Also, I'd rather not have to edit /etc/dhcp/dhclient.conf to change my static IP since it seems I should be able to do this by only editing interfaces. Can anyone explain the issues I'm seeing above and suggest the best way of making changes to static IP addresses take effect that admits reproducibility so that I can be sure that my approach works?

  • Are two periods allowed in the local-part of an email address?

    - by Mike B
    A third-party email gateway relay is refusing to process a message for an email address we're sending to. The address is in the format of [email protected] (note the two periods). Is this allowed by RFC guidelines? RFC 2822 seems to object to this in section 3.4.1: The locally interpreted string is either a quoted-string or a dot-atom. If the string can be represented as a dot-atom (that is, it contains no characters other than atext characters or "." surrounded by atext characters), then the dot-atom form SHOULD be used and the quoted-string form SHOULD NOT be used. Comments and folding white space SHOULD NOT be used around the "@" in the addr-spec. Furthermore, in that same section, it references this: addr-spec = local-part "@" domain local-part = dot-atom / quoted-string / obs-local-part I interpret this to mean that the localpart can have content separated by dots but there cannot be two successive dots, and it cannot start or end with a dot. That being said, I'm not familiar with dot-atom syntax so maybe I'm mistaken here. Can someone please confirm and explain?

  • Using a second Wifi Router (in order to use a LAN port)

    - by Sledge81
    Problem: Connecting a TV decoder via Internet. It doesn't have inbuilt wifi so wired LAN is the only option. I bought a second Wifi Router so I could use its LAN port to create a wired internet connection to my decoder. What I want to achieve: The second Wifi Router should basically pick up the signal from the main wifi router. I would then use the LAN port to connect (with a wire) to the TV decoder. In other words have my secondary Wifi Router act as an access point, which will enable me to use a wired LAN connection to the decoder. What i've done so far: Connected the second Wifi Router to my laptop via the LAN ports. Access 192.168.1.1 and went into my second router. 1) SSID set to the same one as the main Wifi Router 2) Tried disabling DHCP and enabling DHCP (with the DNS and default gateway configured the same as the main router). When I check my network connections, I see the LAN connection too but it says 'Not connected to the internet' while the Wifi (main router) shows connected. Can someone please advise on how to use my second Wifi Router to connect to the main Wifi Router (and thus the Internet). Thanks. main wifi router: Zyxel secondary wifi router: TP Link

  • Local traffic through VPN, global traffic through WAN

    - by ikonoma
    I have an issue with my internet connection. I am using VPN (Aventail Client) to access the local resources. When connected to VPN the Internet traffic passes through it, not through my LAN or Wi-Fi network. I would like to change the routing table to use the Wi-Fi adapter of the PC for WAN traffic. I have routing file, which works very well and routes the traffic in this way, but only when I am physically connected to the local network through LAN. But I can't set it to work with the VPN connection, because I have no gateway when I am connected to it. Etc this in bold is missing. What to do? route change 0.0.0.0 mask 0.0.0.0 172.16.76.1 metric 200 if 12 route change 0.0.0.0 mask 0.0.0.0 10.44.2.1 metric 400 if 11 route add 150.251.0.0 mask 255.255.0.0 10.44.2.1 metric 100 if 11 route add 10.0.0.0 mask 255.0.0.0 10.44.2.1 metric 100 if 11 pause

  • How to prevent response to who-has requests on virtual eth interface?

    - by user42881
    Hi, we use small embedded X86 linux servers equipped with a single physical ethernet port as a gateway for an IP video surveillance application. Each downstream IP cam is mapped to a separate virtual IP address like this: real eth0 IP address= 192.168.1.1, camera 1 (eth0:1) =192.168.1.61, camera 2 (eth0:2) =192.168.1.62, etc. etc. all on the same eth0 physical port. This approach works well, except that a specific third-party windows video recording application running on a separate PC on the same LAN, automatically pings the virtual IPs looking for unique who-has responses on system startup and, when it gets back the same eth0 MAC address for each virtual interface, freaks out and won't allow us to subsequently manually enter those addresses. The windows app doesn't mind, tho, if it receives no answer to the who-has ping. My question - how can we either (a) shut off the who-has responses just for the virtual eth0:x interfaces while keeping them for the primary physical eth0 port, or, in the alternative, spoof a valid but different MAC address for each virtual interface? Thanks!

  • Xen HVM Windows 2008 network bridge

    I have a problem with the Windows Server 2008 guest (hvm). I can't get a network interface running for him. I also have a Debian guest and it's working ok, but I can't do it with the Win2k8 guest.

  • Lenovo Thinkpad T430 not booting from HDD if there is a USB modem connected

    - by user93353
    I have a T430 Levono Thinkpad running Win7. I use a ZTE USB modem (something like this) for my internet connection. I usually keep the modem plugged into the USB drive even when the laptop is shutdown or hibernating. This worked fine on my earlier laptops. But with the Lenovo, my laptop doesn't boot if the modem is in the USB drive. It shows the initial character based screen where it gives the Thinkpad message & BIOS details and then waits. If I pull out the modem, it goes ahead. I have disabled USB as a boot option in my BIOS settings, but even then this happens sometimes (but not all the times). Likewise while resuming from hibernation. The USB modem also has drivers & ISP connection client which getting installed the first time you use it on any machine. I have used multiple laptops (HP, DELL, Acer, Gateway) but never faced this problem before. I have friends who use other Thinkpad models but haven't faced this issue. Any resolutions, workarounds for this?

  • Formatting a former RAID 0 drive through USB

    - by EXC
    I'll try to be as specific as possible here: I was using two Hitachi 2.5" 500 gb HDDs in my Gateway P-7805u laptop in a RAID 0 configuration. The array was causing the laptop to run extremely hot, however, so I removed them and deleted the RAID array through Intel Matrix HDD manager. I did a clean install of Windows 7 on the original 320 gb HDD that came with the laptop. I never did format the original RAID array HDDs before taking them out of the computer. Now, I am attempting to format the Hitachi 500 gb RAID array HDDs externally through a USB external enclosure. The external HDD drivers install on my clean install OS, but when I go into 'My Computer' there is no external drive available. I cannot format in CMD Prompt because my computer will not designate a drive letter to the external HDD. The drivers install and the HDD is recognized as a Hitachi external drive, but nothing seems to show up in my computer window. I need to know if there is a way to format these drives to NTFS externally.

  • OpenVPN / iptables restrict some access

    - by RitonLaJoie
    I want to create an openvpn service on a dedicated server I have, for some friends so that they are able to play online games faster. Is there an easy way to restrict which traffic I allow them with iptables ? It seems iptable is not very easy to maintain and we can easily get kicked out of our own server. Rebooting on a rescue mode every time I would get kicked out because of bad iptable rules would just be a pain. As far as I understand, the tun interface would be providing the access. Which kind of rule in iptables would I have to implement to restrict their access to only 1 ip ? Also, I don't want this vpn to be the default gateway for all the traffic. I guess I should go with the option of pushing a route to the clients so that they connect to the IP of the game server through the VPN and use their regular routes through their ISP for all the other traffic ? As a side not, it seems Openvpn AS is not very robust. Is there some other (commercial is ok) product that would give me the same administration options through a web interface ? Is Webmin the only other solution ? Thanks !

  • Using iptables to make a VPN router

    - by lost_in_the_sauce
    I am attempting to make a VPN connection to a third party VPN site, then forward traffic from my internal computers (ssh and ping for now) out to the VPN site using IPTables. 3rd Party <- (tun0/eth0)Linux VPN Box(eth1) <- Windows7TestBox I am running on CentOS 6.3 Linux and have two network connections eth0-public eth1-private. I am running vpnc-0.5.3-4 which is currently connecting to my destination. When I connect I am able to ping the destination IPAddresses but that is as far as I can get. ping -I tun0 10.1.33.26 success ping -I eth0 10.1.33.26 fail ping -I eth1 10.1.33.26 fail I have my private network Windows 7 test box set up to have the eth1 (private) network of my VPN Server as its gateway and can ping him fine. I need IPTables to send the Windows 7 traffic out the VPN tunnel. I have tried for a few days many different IPTables configurations from this site and others, either the other examples are too simple or overly complicated. The only thing this server is doing is connecting to the VPN and forwarding all traffic. So we can "flush" everything and start from scratch here. It is a blank slate. #!/bin/bash echo "Define variables" ipt="/sbin/iptables" echo "Zero out all counters" $ipt -Z $ipt -t nat -Z $ipt -t mangle -Z echo "Flush all active rules, delete all chains" $ipt -F $ipt -X $ipt -t nat -F $ipt -t nat -X $ipt -t mangle -F $ipt -t mangle -X $ipt -P INPUT ACCEPT $ipt -P FORWARD ACCEPT $ipt -P OUTPUT ACCEPT $ipt -t nat -A POSTROUTING -o tun0 -j MASQUERADE $ipt -A FORWARD -i eth1 -o eth0 -j ACCEPT $ipt -A FORWARD -i eth0 -o eth1 -j ACCEPT $ipt -A FORWARD -i eth0 -o tun0 -j ACCEPT $ipt -A FORWARD -i tun0 -o eth0 -j ACCEPT Again I have done many variations of the above and many other rules from other posts but haven't been able to move forward. It seems like such a simple task, and yet....

  • Windows 7 computer apparently connected to working wireless network but can't access router page or internet

    - by Hemmer
    I can consistently connect successfully to both the router and the internet using both my phone and two different computers which strongly suggests that the issue is at the desktop end. Only my Windows 7 desktop machine has stopped getting internet connectivity. It manages to connect to the router's network using the Windows 7 wireless dialog, but can't access either the router configuration page (192.168.1.1) or the internet in general once connected. The strange thing is the wireless network icon in the notification bar shows a full strength signal, sometimes with the yellow warning triangle. The output of ipconfig /all is: Wireless LAN adapter Wireless Network Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Broadcom 802.11g Network Adapter Physical Address. . . . . . . . . : 00-12-17-94-98-90 DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes IPv4 Address. . . . . . . . . . . : 192.168.1.102(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Lease Obtained. . . . . . . . . . : 08 June 2011 10:32:16 Lease Expires . . . . . . . . . . : 08 June 2011 12:32:16 Default Gateway . . . . . . . . . : 192.168.1.1 DHCP Server . . . . . . . . . . . : 192.168.1.1 DNS Servers . . . . . . . . . . . : 194.168.4.100 194.168.8.100 NetBIOS over Tcpip. . . . . . . . : Enabled I've tried renewing DCHP settings disabling IPv6 resetting TCP stack uninstalling and reinstalling WLAN card drivers I've not installed anything new or made any changes to my knowledge, this just happened out of the blue. The only possible change is my friend connected his macbook to the network, but that has gone now and shouldn't have any lasting effects? TCP/IPv4 is set to automatically find an IP address. Antivirus is MSE (up to date) and doesn't detect anything unusual. Any ideas where to go next? Any help is greatly appreciated. For reference, the results of ipconfig /all on one of the working computers is: Ethernet adapter Wireless Network Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Broadcom 802.11g Network Adapter Physical Address. . . . . . . . . : 00-16-CF-67-E5-97 Dhcp Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes IP Address. . . . . . . . . . . . : 192.168.1.100 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.1.1 DHCP Server . . . . . . . . . . . : 192.168.1.1 DNS Servers . . . . . . . . . . . : 194.168.4.100 194.168.8.100 Lease Obtained. . . . . . . . . . : 08 June 2011 10:26:38 Lease Expires . . . . . . . . . . : 08 June 2011 12:26:38 UPDATE: Still not working, but I've managed to find a temporary workaround by tethering my Android phone, effectively becoming a new wifi adapter. Will be moving to a new flat so will test if it is a network specific thing - maybe the card has got damaged somehow? Also will see if the card is working with Linux soon.

  • How to route 1 VPN through another on OS X?

    - by Eeep
    Hi everyone. Thanks a lot for your help! I've been tinkering with this for a while and have read many posts along with Googling for help, but my knowledge of TCP/IP is really weak... I have access to two different VPN servers. 1 Is set up in Network Settings and connects through PPP 2 Is set up through Tunnelblick and uses OpenVPN. I can connect to either tunnel #1 or tunnel #2, but not both one after the other... One of my major to-do's this year is study TCP/IP, but for now, would you be super-helpful and help me fix this really clearly? I have no experience with routing, DNS, gateways or any of that. If you tell me, "Set your gateway to XXX.XXX.XX.XXX" can you specify how I get that IP, off of what interface so I don't get messed up? I can figure out the terminal just fine if you let me know what to type, and I WILL read the man pages on everything you help me with. Thanks a million!

  • Iptables state tracking

    - by complexgeek
    Hi there. I've just taken over administration of a fairly complex firewall ruleset for a firewall box running Fedora Core 12, and there's one thing about it that is puzzling me. When I run nmap on the gateway from outside the network, I see all the expected services, but also sunrpc on port 111. The INPUT chain has DEFAULT DROP set, and there is no rule allowing port 111. As best I can tell (watching the packet counters before/during/after the scan) it's being allowed by the rule: "-m state --state RELATED,ESTABLISHED -j ACCEPT" but I don't understand why a brand new TCP connection would be considered RELATED or ESTABLISHED. Any suggestions would be greatly appreciated.

There are a variety of tools available to help you and Support diagnose SOA Suite issues in 11g but it can be confusing as to which tool is appropriate for a particular situation and what their relationships are. This blog post will introduce the various tools and attempt to clarify what each is for and how they are related. Let's first list the tools we'll be addressing: RDA: Remote Diagnostic Agent DFW: Diagnostic Framework Selective Tracing DMS: Dynamic Monitoring Service ODL: Oracle Diagnostic Logging ADR: Automatic Diagnostics Repository ADRCI: Automatic Diagnostics Repository Command Interpreter WLDF: WebLogic Diagnostic Framework This overview is not mean to be a comprehensive guide on using all of these tools, however, extensive reference materials are included that will provide many more details on their execution. Another point to note is that all of these tools are applicable for Fusion Middleware as a whole but specific products may or may not have implemented features to leverage them. A couple of the tools have a WebLogic Scripting Tool or 'WLST' interface. WLST is a command interface for executing pre-built functions and custom scripts against a domain. A detailed WLST tutorial is beyond the scope of this post but you can find general information here. There are more specific resources in the below sections.In this post when we refer to 'Enterprise Manager' or 'EM' we are referring to Enterprise Manager Fusion Middleware Control. read the full blog post here.

For access to the Oracle demo systems please visit OPN and talk to your Partner Expert DSS is pleased to announce the availability of the demo “Business Driven Development“. This innovative demonstration uses a case-study approach to show business users how they can easily streamline their Business Processes - delivering greater efficiency, agility, visibility and collaboration with Oracle BPM and WebCenter. The BDD demonstration uses a case study-based approach to highlight a business problem at a fictional company, Avitek Corporation, and uses Oracle BPM and Oracle WebCenter to solve the business problem. This holistic approach has specifically been used to appeal to a non-technical business analyst user. This demo is NOT focused on product features, but aims to guide users through a complete BPM lifecycle. The scenario is based on improving a simple order process (scenario details are in the demo script). Avitek Corporation is sufferinng from a manual email-driven ordering process. Sales reps don’t know where the customer orders are stuck (no visibility) and finance users are unable to manually approve every order (no automation). There are several areas where this process can be improved with Business Process Management technology. This demo shows how improving following areas will ignificantly help resolve the business problems Avitek Corporation is facing. Areas for improvement include: Utilizing BPM for process management, rather than an unregulated, email-based process. Utilizing automated services, rather than requiring a human to key into a system. For example, Finance checking the customer’s credit rating is something that could be automated. Centralizing business rules that can be integrated into a business process, rather than requiring a human to process them. For example, Finance must determine when orders can be automatically approved. Provide insight and visibility into the process. For example, Sales Rep needs to know the status of their customer’s orders. The BDD Demo uses the following products.

These new, reusable usability solutions and best-practices, which will join the Oracle dashboard patterns and guidelines that are already available online, are used by Oracle to artfully bring to life a new standard in the user experience, or UX, of enterprise applications. Now, the Oracle applications development community can benefit from the science behind the Oracle Fusion Applications user experience, too. These Oracle Fusion Applications UX Design Patterns, or blueprints, enable Oracle applications developers and system implementers everywhere to leverage professional usability insight when: tailoring an Oracle Fusion application, creating coexistence solutions that existing users will be delighted with, thus enabling graceful user transitions to Oracle Fusion Applications down the road, or designing exciting, new, highly usable applications in the cloud or on-premise. Based on the Oracle Application Development Framework (ADF) components, the Oracle Fusion Applications patterns and guidelines are proven with real users and in the Applications UX usability labs, so you can get right to work coding productivity-enhancing designs that provide an advantage for your entire business. What’s the best way to get started? We’ve made that easy, too. The Design Filter Tool (DeFT) selects the best pattern for your user type and task. Simply adapt your selection for your own task flow and content, and you’re on your way to a really great applications user experience. More Oracle applications design patterns and training are coming your way in the future. To provide feedback on the sets that are currently available, let me know in the comments!

  • Linux router: ping doesn't route back

    - by El Barto
    I have a Debian box which I'm trying to set up as a router and an Ubuntu box which I'm using as a client. My problem is that when the Ubuntu client tries to ping a server on the Internet, all the packets are lost (though, as you can see below, they seem to go to the server and back without problem). I'm doing this in the Ubuntu Box: # ping -I eth1 my.remote-server.com PING my.remote-server.com (X.X.X.X) from 10.1.1.12 eth1: 56(84) bytes of data. ^C --- my.remote-server.com ping statistics --- 13 packets transmitted, 0 received, 100% packet loss, time 12094ms (I changed the name and IP of the remote server for privacy). From the Debian Router I see this: # tcpdump -i eth1 -qtln icmp tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth1, link-type EN10MB (Ethernet), capture size 65535 bytes IP X.X.X.X > 10.1.1.12: ICMP echo reply, id 305, seq 7, length 64 IP 10.1.1.12 > X.X.X.X: ICMP echo request, id 305, seq 8, length 64 IP X.X.X.X > 10.1.1.12: ICMP echo reply, id 305, seq 8, length 64 IP 10.1.1.12 > X.X.X.X: ICMP echo request, id 305, seq 9, length 64 IP X.X.X.X > 10.1.1.12: ICMP echo reply, id 305, seq 9, length 64 IP 10.1.1.12 > X.X.X.X: ICMP echo request, id 305, seq 10, length 64 IP X.X.X.X > 10.1.1.12: ICMP echo reply, id 305, seq 10, length 64 IP 10.1.1.12 > X.X.X.X: ICMP echo request, id 305, seq 11, length 64 IP X.X.X.X > 10.1.1.12: ICMP echo reply, id 305, seq 11, length 64 ^C 9 packets captured 9 packets received by filter 0 packets dropped by kernel # tcpdump -i eth2 -qtln icmp tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth2, link-type EN10MB (Ethernet), capture size 65535 bytes IP 192.168.1.10 > X.X.X.X: ICMP echo request, id 360, seq 213, length 64 IP X.X.X.X > 192.168.1.10: ICMP echo reply, id 360, seq 213, length 64 IP 192.168.1.10 > X.X.X.X: ICMP echo request, id 360, seq 214, length 64 IP X.X.X.X > 192.168.1.10: ICMP echo reply, id 360, seq 214, length 64 IP 192.168.1.10 > X.X.X.X: ICMP echo request, id 360, seq 215, length 64 IP X.X.X.X > 192.168.1.10: ICMP echo reply, id 360, seq 215, length 64 IP 192.168.1.10 > X.X.X.X: ICMP echo request, id 360, seq 216, length 64 IP X.X.X.X > 192.168.1.10: ICMP echo reply, id 360, seq 216, length 64 IP 192.168.1.10 > X.X.X.X: ICMP echo request, id 360, seq 217, length 64 IP X.X.X.X > 192.168.1.10: ICMP echo reply, id 360, seq 217, length 64 ^C 10 packets captured 10 packets received by filter 0 packets dropped by kernel And at the remote server I see this: # tcpdump -i eth0 -qtln icmp tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes IP Y.Y.Y.Y > X.X.X.X: ICMP echo request, id 360, seq 1, length 64 IP X.X.X.X > Y.Y.Y.Y: ICMP echo reply, id 360, seq 1, length 64 IP Y.Y.Y.Y > X.X.X.X: ICMP echo request, id 360, seq 2, length 64 IP X.X.X.X > Y.Y.Y.Y: ICMP echo reply, id 360, seq 2, length 64 IP Y.Y.Y.Y > X.X.X.X: ICMP echo request, id 360, seq 3, length 64 IP X.X.X.X > Y.Y.Y.Y: ICMP echo reply, id 360, seq 3, length 64 IP Y.Y.Y.Y > X.X.X.X: ICMP echo request, id 360, seq 4, length 64 IP X.X.X.X > Y.Y.Y.Y: ICMP echo reply, id 360, seq 4, length 64 IP Y.Y.Y.Y > X.X.X.X: ICMP echo request, id 360, seq 5, length 64 IP X.X.X.X > Y.Y.Y.Y: ICMP echo reply, id 360, seq 5, length 64 IP Y.Y.Y.Y > X.X.X.X: ICMP echo request, id 360, seq 6, length 64 IP X.X.X.X > Y.Y.Y.Y: ICMP echo reply, id 360, seq 6, length 64 IP Y.Y.Y.Y > X.X.X.X: ICMP echo request, id 360, seq 7, length 64 IP X.X.X.X > Y.Y.Y.Y: ICMP echo reply, id 360, seq 7, length 64 IP Y.Y.Y.Y > X.X.X.X: ICMP echo request, id 360, seq 8, length 64 IP X.X.X.X > Y.Y.Y.Y: ICMP echo reply, id 360, seq 8, length 64 IP Y.Y.Y.Y > X.X.X.X: ICMP echo request, id 360, seq 9, length 64 IP X.X.X.X > Y.Y.Y.Y: ICMP echo reply, id 360, seq 9, length 64 18 packets captured 228 packets received by filter 92 packets dropped by kernel Here "X.X.X.X" is my remote server's IP and "Y.Y.Y.Y" is my local network's public IP. So, what I understand is that the ping packets are coming out of the Ubuntu box (10.1.1.12), to the router (10.1.1.1), from there to the next router (192.168.1.1) and reaching the remote server (X.X.X.X). Then they come back all the way to the Debian router, but they never reach the Ubuntu box back. What am I missing? Here's the Debian router setup: # ifconfig eth1 Link encap:Ethernet HWaddr 94:0c:6d:82:0d:98 inet addr:10.1.1.1 Bcast:10.1.1.255 Mask:255.255.255.0 inet6 addr: fe80::960c:6dff:fe82:d98/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:105761 errors:0 dropped:0 overruns:0 frame:0 TX packets:48944 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:40298768 (38.4 MiB) TX bytes:44831595 (42.7 MiB) Interrupt:19 Base address:0x6000 eth2 Link encap:Ethernet HWaddr 6c:f0:49:a4:47:38 inet addr:192.168.1.10 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::6ef0:49ff:fea4:4738/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:38335992 errors:0 dropped:0 overruns:0 frame:0 TX packets:37097705 errors:0 dropped:0 overruns:0 carrier:1 collisions:0 txqueuelen:1000 RX bytes:4260680226 (3.9 GiB) TX bytes:3759806551 (3.5 GiB) Interrupt:27 eth3 Link encap:Ethernet HWaddr 94:0c:6d:82:c8:72 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:20 Base address:0x2000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:3408 errors:0 dropped:0 overruns:0 frame:0 TX packets:3408 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:358445 (350.0 KiB) TX bytes:358445 (350.0 KiB) tun0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:10.8.0.1 P-t-P:10.8.0.2 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:2767779 errors:0 dropped:0 overruns:0 frame:0 TX packets:1569477 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:3609469393 (3.3 GiB) TX bytes:96113978 (91.6 MiB) #
