  • Cisco ASA - Enable communication between same security level

    - by Conor
    I have recently inherited a network with a Cisco ASA (running version 8.2). I am trying to configure it to allow communication between two interfaces configured with the same security level (DMZ-DMZ) "same-security-traffic permit inter-interface" has been set, but hosts are unable to communicate between the interfaces. I am assuming that some NAT settings are causing my issue. Below is my running config: ASA Version 8.2(3) ! hostname asa enable password XXXXXXXX encrypted passwd XXXXXXXX encrypted names ! interface Ethernet0/0 switchport access vlan 400 ! interface Ethernet0/1 switchport access vlan 400 ! interface Ethernet0/2 switchport access vlan 420 ! interface Ethernet0/3 switchport access vlan 420 ! interface Ethernet0/4 switchport access vlan 450 ! interface Ethernet0/5 switchport access vlan 450 ! interface Ethernet0/6 switchport access vlan 500 ! interface Ethernet0/7 switchport access vlan 500 ! interface Vlan400 nameif outside security-level 0 ip address XX.XX.XX.10 255.255.255.248 ! interface Vlan420 nameif public security-level 20 ip address 192.168.20.1 255.255.255.0 ! interface Vlan450 nameif dmz security-level 50 ip address 192.168.10.1 255.255.255.0 ! interface Vlan500 nameif inside security-level 100 ip address 192.168.0.1 255.255.255.0 ! ftp mode passive clock timezone JST 9 same-security-traffic permit inter-interface same-security-traffic permit intra-interface object-group network DM_INLINE_NETWORK_1 network-object host XX.XX.XX.11 network-object host XX.XX.XX.13 object-group service ssh_2220 tcp port-object eq 2220 object-group service ssh_2251 tcp port-object eq 2251 object-group service ssh_2229 tcp port-object eq 2229 object-group service ssh_2210 tcp port-object eq 2210 object-group service DM_INLINE_TCP_1 tcp group-object ssh_2210 group-object ssh_2220 object-group service zabbix tcp port-object range 10050 10051 object-group service DM_INLINE_TCP_2 tcp port-object eq www group-object zabbix object-group protocol TCPUDP protocol-object udp protocol-object tcp object-group service http_8029 tcp port-object eq 8029 object-group network DM_INLINE_NETWORK_2 network-object host 192.168.20.10 network-object host 192.168.20.30 network-object host 192.168.20.60 object-group service imaps_993 tcp description Secure IMAP port-object eq 993 object-group service public_wifi_group description Service allowed on the Public Wifi Group.

  • Share the DVB card on windows 7

    - by Bashar Kernel
    I have 2 computers connected to a router and I have a DVB card in one of them. I want to use the one DVB card to feed both of them. I read about it and I know that I want to share the DVB adapter with the Internet Connection Sharing on the LAN network. But when I use the connection sharing, I lose my internet access I tried to use "Bridge Connection", but then I also lost my internet access too. Can any one tell me how to fix this problem? And how to view the channels (for example how to use the VLC)?

  • Linux bcm43224 wifi adapter slows down a couple minutes after boot

    - by Blubber
    I just installed Ubuntu on my mid 2012 MacBook Air. Everything worked out of the box, but the wifi is showing some weird behavior. When I first login it's really fast, loading google.com is near instant, and browsing in general feels at least as smooth as it did on Mac OS. However, after a couple minutes the connection slows down dramatically, sometimes it takes over 5s to load google.com, a simple reboot fixes the problem for another couple minutes. Specs: Wifi: 02:00.0 Network controller: Broadcom Corporation BCM43224 802.11a/b/g/n (rev 01) Driver: open-source brcmsmac driver Kernel: Linux wega 3.8.0-21-generic #32-Ubuntu SMP Tue May 14 22:16:46 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux Distro: Ubuntu 13.04 (uptodate) I tried a number of things, none of which actually helped Use proprietary sta driver from broadcom Installed firmware into /lib/firmware/brcms (which, as far as I can tell from logs, does not get loaded at all) Switch router to only use 2.4 OR 5 GHz Set router to only use a OR g OR n Set router to use AES encryption only Turned off power management on the adapter Set regulatory region to the correct value (NL) on both router and laptop Disable ipv6 Nothing seems to help, the slowdown always occurs. I did notice that the latency (ping google.com) stays roughly the same (around 9ms). Below is some more information that might be of use. $ lspci -nnk | grep -iA2 net 02:00.0 Network controller [0280]: Broadcom Corporation BCM43224 802.11a/b/g/n [14e4:4353] (rev 01) Subsystem: Apple Inc.

  • Ping isn't acting accurate?

    - by Earlz
    I've been trying to diagnose some latency issues with my internet connection. I've been lagging out of online video games and such, which of course could be their server's fault. So, I've been running ping some. It doesn't indicate anything unusual, but it does act a bit strange. I can start it with something like ping internethost -i 0.1 so that it will send a ton of packets, and every 10-20 seconds it will appear to just freeze for 2 or 3 seconds. The packets are still being received in the right order though, and there is no packet loss. The weirdest thing is that after the little freeze up, it will usually just report a ping time that is about 10-30ms higher than the average. How does this happen? Is ping still being accurate? I'm using Arch Linux. The host I'm pinging is my website, which shouldn't be doing any kind of ping slowing or filtering.

  • Running DNS locally for home network

    - by Roy Rico
    I have a small home network that just got larger ( New roommate, My existing roommate got a laptop (on top of her computer)j, my friends coming over with laptop, etc ). I'd like to run a local DNS server for lookups of my local network stuff (fileserver.local, windowsTV.local, machineA.local, machineB.local, appletv.local). I used to have a business line with a static IP, and run bind/named internally. However, now, I have a normal account. My ISP's DNS servers are constantly changing (for whatever reasons my ISP doesn't like to keep the same IP range for long). I need my local DNS to be automatically updated to use my ISP's DNS for external traffic, but be able to maintain an internal DNS server (getting to update the hosts file is being a hassle with every new machine on top of rebuilding existing machines with win7 or Ubuntu 9.04). Additionally, My ISP's DNS servers often crash or become unresponsive. Are there any open DNS servers that are reliable (i don't want to reconfig every day) that I could use as my primary, then if those fail, then use my ISP's? UPDATE: Also looking for each workstation to be able to use dhcp to connect, but instead of getting ISP dns servers, getting my internal one.... Thanks

  • Can't ping devices by IP address for devices allocated IPs by DHCP

    - by GiddyUpHorsey
    I have a home network with a Trendnet wireless router and a Windows Domain. The Domain Controller/DNS server is a Windows 2000 Server and is configured to forward queries to DNS servers provided by the ISP. The router provides DHCP and is configured with the Windows 2000 Server as the DNS server. The network has been set up for a couple of years and usually works fine. When I connect iPhones to the network over WiFi, the router can ping the iPhones through its browser based admin interface, but Windows machines that are part of the Windows Domain cannot. A laptop was connected to the network over WiFi that wasn't joined to the domain and it could see the iPhones. The router UI shows that the laptop has a reserved IP allocated via DHCP. All machines either have a static or DHCP allocated IP on the 192.168.0.* subnet. Router - 192.168.0.1 - Static - Wired Windows Domain Controller - 192.168.0.8 - Static - Virtual Windows 7 Workstation - 192.168.0.200 - DHCP Auto - Wired VMWare ESXi Host - 192.168.0.201 - Static? - Wired iPhone 1 - 192.168.0.202 - DHCP Auto - WiFi iPhone 2 - 192.168.0.203 - DHCP Auto - WiFi Windows Vista Laptop - 192.168.0.204 - DHCP Reserved - WiFi Using the Windows 7 machine (200), I try to ping each machine and the only DHCP machine that responds is itself. The other DHCP machines fail with Reply from 192.168.0.200: Destination host unreachable.. Using nslookup fails with *** domain.controller.name can't find 192.168.0.203: Non-existent domain. Using the Windows 2000 Domain Controller (8), I try to ping each machine and the only DHCP machine that responds is the Windows 7 machine (200). Pinging the other DHCP machines fails with Request timed out.. Using nslookup also fails with *** domain.controller.name can't find 192.168.0.203: Non-existent domain. Using the iPhone 2 (203), I try to ping (Network Ping Lite) the machines with static IP addresses and that works fine. When I try to ping the Windows 7 machine (200) it is unable to get a response. How do I configure the DNS server/Windows Domain/Router properly so that the Windows Domain machines can see the IPs allocated via DHCP?

  • Slow internet using Arch Linux

    - by GZaidman
    after a week or so of using Arch Linux I cant access the internet - it takes around 5 mins to load google (most of the other websites just give me a timeout), pacman's downloading speed range between 5-2Kbs, and pinging google takes around 9Kms. I'm connected using wireless network (wifi card is Intel Ultimate 6300 and router is Edimax 6524n). Every other Windows machine that's connected to the network (and even the T410 running Windows) is fine, so the problem lies in Linux. So far, i checked the resolv.conf file (my router ip address is listed), and the hosts file (pretty much default), and I disabled the ipv6 module. None of that helped. PS: i'm using NetworkManager (but the problem still occurs when connecting using wicd) running on Gnome3. Thanks in advance for any help you can provide! EDIT: something really strange happens whenever I ping google: i get an unknown host 'google.com', but the bit rate from the card jumps at the exact second I ping google (so far, the bit rate jumped to 54Mb/s from 1Mb/s over the course of 4 pings).

  • How to eliminate the downtime when a dynamic IP address changes?

    - by xenon
    We currently have a number of client computers linked up to a database server (MS SQL 2008) for replication. The database server recognises the computers based on their Windows hostname. We are using dynamic IP addresses at this time because we tend to change the computers’ hardware quite frequently, and so the MAC address may be different. Unless static IP has a good way for us to manage frequent changing of MAC addresses, we are keeping it to dynamic IP. The problem with dynamic IP addresses, however, is that when a client fetches an new IP from the DHCP, ie, there is a change in the IP address, there is going to have a downtime for the hostname to reflect the new IP address, the client’s DNS cache of the hostname to reload, and also the server’s DNS cache to reload to see the new IP from the hostname. All of these have different timings and the delay can be really bad at times. Restarting the computer doesn't work all the time too. The clients are on Windows 7. How can I eliminate the amount of downtime required when there is a change in IP in the case of dynamic IP addresses?

  • WD my cloud 4th is Super Slow

    - by Saduser
    I am using a WD my cloud 4Tb and I have read other posts about users complaining about getting only 10Mb per second. My problem is that I am getting about 100kb/s to transfer a 125gb iPhoto library. Estimated time is 11 days to transfer this file. This is unacceptable. On the back of the WD cloud I am getting a solid green light and from what I read this means that I am on a gigabyte network. I have mac book pro running Mac OS Mavericks. I have tried 4 different cables and turned off my router firewall. I don't run anti-virus nor any firewall on the mac. Other things I have checked: direct connection to both router and WD cloud device. Tried wireless but it is even slower. Previously I was able to transfer a 55Gb iPhoto library in 14 hours which I felt was acceptable. I figured it would take approximately double the time to transfer the 125gb file but 11 days is ridiculous. Any other suggestions? Anything else I can check (how to check it) what is the bottle neck?

  • Set up router to vpn into proxy server

    - by NKimber
    I have a small network with a single LinkSys router connected to broadband in US via Comcast. I have a VPN proxy server account that I can use with a standard Windows connection, allowing me to have a geographic IP fingerprint in Europe, this is useful for a number of purposes. I want to setup a 2nd router that automatically connects via VPN to this proxy service, so any hardware that is connected to router 2 looks as though it is originating network requests in Europe, and any hardware connected to my main router has normal Comcast traffic (all requests are originating from USA). My 2nd router is a LinkSys WRT54G2, I'm having trouble getting this configured. Question, is what I'm trying to do even feasible? Should the WRT54G2 be able to do this with native functionality? Would flashing it with DD-WRT allow me to achieve my objectives? Any help/suggestions much appreciated. Neil

  • Troubleshooting web timeouts with a Belkin router

    - by rexzilla
    I have a Belkin FSD7632-4 ADSL wifi router. Ever since I got it, I've faced this problem of websites timing out. For example, I go to flickr.com, and the images won't load because they come from farm1.static.flickr.com. Either I wait 10 minutes or so until the timed out sockets are closed and retry (with variable results) or I reboot the router. This happens irrespective of whether I use wired or wifi network. I'm in India, using Airtel Broadband, and if I use my ISP supplied Beetel 220BX ADSL router (which has no wifi and only one LAN port), everything works fine. I copied over the broadband settings from my old router: VPI/VCI values=1/32 Encapsulation=LLC MTU=1492 I have not enabled any firewall on the router. Is there anything else I can try? Or is it a defect with the router and should I take it back for a replacement? I bought it just 2 months ago.

  • applescript: establish PPPoE connection

    - by user26700
    how would an Applescript look like that connects to a specific PPPoE configuration? i want to trigger this via Launchbar. (or a more fancy script which checks if the current chosen network location is the right one and if an ethernet cable is plugged in, then connect to the PPPoE service automatically. i'd be completely satisfied with the simpler version though)

  • outgoing DNS flood targeted to non-ISP hosts

    - by radudani
    Below is the specific traffic monitored at the network perimeter and originating from a user PC on Vista platform. My question is not about the effects of the flood, but about the nature of the source of it. Is this some known infection, or just an application went out of control? a standard NOD32 scan didn't find anything, as the user told me. Thank you for any hint. 14:40:10.115876 IP 192.168.7.42.4122 > 67.228.0.181.53: S 2742536765:2742536765(0) win 16384 <mss 1460,nop,nop,sackOK> 14:40:10.115943 IP 192.168.7.42.4124 > 67.228.181.207.53: S 3071079888:3071079888(0) win 16384 <mss 1460,nop,nop,sackOK> 14:40:10.116015 IP 192.168.7.42.4126 > 67.228.0.181.53: S 3445199428:3445199428(0) win 16384 <mss 1460,nop,nop,sackOK> 14:40:10.116086 IP 192.168.7.42.4128 > 67.228.181.207.53: S 2053198691:2053198691(0) win 16384 <mss 1460,nop,nop,sackOK> 14:40:10.116154 IP 192.168.7.42.4130 > 67.228.0.181.53: S 2841660872:2841660872(0) win 16384 <mss 1460,nop,nop,sackOK> 14:40:10.116222 IP 192.168.7.42.4132 > 67.228.181.207.53: S 3150822465:3150822465(0) win 16384 <mss 1460,nop,nop,sackOK> 14:40:10.116290 IP 192.168.7.42.4134 > 67.228.0.181.53: S 1692515021:1692515021(0) win 16384 <mss 1460,nop,nop,sackOK> 14:40:10.116358 IP 192.168.7.42.4136 > 67.228.181.207.53: S 3358275919:3358275919(0) win 16384 <mss 1460,nop,nop,sackOK> 14:40:10.116430 IP 192.168.7.42.4138 > 67.228.0.181.53: S 930184999:930184999(0) win 16384 <mss 1460,nop,nop,sackOK> 14:40:10.116498 IP 192.168.7.42.4140 > 67.228.181.207.53: S 1504984630:1504984630(0) win 16384 <mss 1460,nop,nop,sackOK> 14:40:10.116566 IP 192.168.7.42.4142 > 67.228.0.181.53: S 546074424:546074424(0) win 16384 <mss 1460,nop,nop,sackOK> 14:40:10.116634 IP 192.168.7.42.4144 > 67.228.181.207.53: S 4241828590:4241828590(0) win 16384 <mss 1460,nop,nop,sackOK> 14:40:10.116702 IP 192.168.7.42.4146 > 67.228.0.181.53: S 668634627:668634627(0) win 16384 <mss 1460,nop,nop,sackOK> 14:40:10.116769 IP 192.168.7.42.4148 > 67.228.181.207.53: S 3768119461:3768119461(0) win 16384 <mss 1460,nop,nop,sackOK> 14:40:10.117360 IP 192.168.7.42.4111 > 67.228.0.181.53: 12676 op8 Resp12*- [2128q][|domain] 14:40:10.117932 IP 192.168.7.42.4112 > 67.228.181.207.53: 44190 op7 NotAuth*|$ [29103q],[|domain] 14:40:10.118726 IP 192.168.7.42.4113 > 67.228.0.181.53: 49196 inv_q [b2&3=0xeea] [64081q] [28317a] [43054n] [23433au] Type63482 (Class 5889)?

  • Does a router have a receiving range?

    - by Aadit M Shah
    So my dad bought a TP-Link router (Model No. TL-WA7510N) which apparently has a transmitting range of 1km; and he believes that it also has a receiving range of 1km. So he's arguing with me that the router (which is a trans-receiver) can communicate with any device in the range of 1km whether or not that device has a transmitting range of 1km. To put it graphically: +----+ 1km +----+ | |------------------------------------------------->| | | TR | | TR | | | <----| | +----+ 100m+----+ So here's the problem: The two devices are 1km apart. The first device has a transmitting range of 1km. The second device only has a transmitting range of 100m. According to my dad the two devices can talk to each other. He says that the first device has a transmitting and a receiving range of 1km which means that it can both send data to devices 1km away and receive data from devices 1km away. To me this makes no sense. If the second device can only send data to devices 100m away then how can the first device catch the transmission? He further argues that for bidirectional communication both the sender and the reciver should have overlapping areas of transmission: According to him if two devices have an overlapping area of transmission then they can communicate. Here neither device has enough transmission power to reach the other. However they have enough receiving power to capture the transmission. Obviously this makes absolutely no sense to me. How can a device sense a transmission which hasn't even reached it yet and go out, capture it and bring it back it. To me a trans-receiver only has a transmission power. It has zero receiving power. Hence for two devices to be able to communicate bidirectionally, the diagram should look like: Hence, from my point of view, both the devices should have a transmission range far enough to reach the other for bidirectional communication to be possible; but no matter how much I try to explain to my dad he adamantly disagrees. So, to put an end to this debate once and for all, who is correct? Is there even such a thing as a receiving range? Can a device fetch a transmission that would otherwise never reach it? I would like a canonical answer on this.

  • wmware fusion 5.0.1, LAN, disconnecting from server [closed]

    - by Maxim
    Currently I am using : OSX 10.7.5 VMWare:5.0.1 with windows 7 professional Problem: Getting disconnected from LAN game. Description: 4 of us are trying to play frozen throne on the same network. The thing is, they are all running windows computers, and I am running W7 on VMware. I haven't made any adjustments other than changing from "sharing internet with my mac" to Bridged network "autodetect". When we start to play, everything works then all of a sudden I get disconnected. This happens every once in a while, the timing differs from time to time. None of the others ever disconnects. What could be the problem? Thanks for the help!

  • Are there any wireless webcams/cameras that Windows will recognize as a capture device?

    - by Keithius
    I'd like to have a webcam in a different room from my computer, and the distance means USB is out of the question. I know there are many wireless cameras, but what I can't seem to find out is if any of them would be recognized by Windows as a capture device (just like a locally connected USB webcam). Most of the wireless cameras I can find (e.g., D-Link DCS920; Cisco-Linksys WVC54GCA, etc.) can all stream video directly from the camera itself, which is fine if you're using the camera as a "security" camera (for private use only), but not for other uses (say, sending the video to an online video streaming service, e.g., Ustream). It seems like this should be possible; after all, wireless (WiFi) printers with scanners are recognized by Windows. Are there any wireless (WiFi) cameras out there that would be recognized by Windows as a capture device in the same way as a USB webcam would? Alternatively, a camera that's not wireless (e.g., connects via Ethernet) would do the trick too - but I imagine if anyone is going to make a remote camera like this, they'd go the extra step and make it wireless, too.

  • Redundant OpenVPN connections with advanced Linux routing over an unreliable network

    - by konrad
    I am currently living in a country that blocks many websites and has unreliable network connections to the outside world. I have two OpenVPN endpoints (say: vpn1 and vpn2) on Linux servers that I use to circumvent the firewall. I have full access to these servers. This works quite well, except for the high package loss on my VPN connections. This packet loss varies between 1% and 30% depending on time and seems to have a low correlation, most of the time it seems random. I am thinking about setting up a home router (also on Linux) that maintains OpenVPN connections to both endpoints and sends all packets twice, to both endpoints. vpn2 would send all packets from home to vpn1. Return trafic would be send both directly from vpn1 to home, and also through vpn2. +------------+ | home | +------------+ | | | OpenVPN | | links | | | ~~~~~~~~~~~~~~~~~~ unreliable connection | | +----------+ +----------+ | vpn1 |---| vpn2 | +----------+ +----------+ | +------------+ | HTTP proxy | +------------+ | (internet) For clarity: all packets between home and the HTTP proxy will be duplicated and sent over different paths, to increase the chances one of them will arrive. If both arrive, the first second one can be silently discarded. Bandwidth usage is not an issue, both on the home side and endpoint side. vpn1 and vpn2 are close to each other (3ms ping) and have a reliable connection. Any pointers on how this could be achieved using the advanced routing policies available in Linux?

  • How do I Ban/un-ban users in Hamachi2?

    - by Paige Watson
    I was using Hamachi (v1) and banned a couple of users for a week. During this time, Hamachi auto-updated to Hamachi2, and now I can't find the ban/un-ban function. Any idea where this is and how to un-ban a user? I tried re-installing the Hamachi (v1) client, but when I started it, it auto-updated to v2.

  • Problems with RDC into Win2008 Server

    - by Jason
    I'm having the same problem with a variety of new machines that I have built. When I RDC into the machine, the display does not update correctly. I get partial images, or refreshes only every 20-30 seconds. It is completely unusable. Eventually, it will even disconnect even though I am logged in. From RDCing into the machine, it looks like the machine is down, but it is fine. I can connect to it with an monitor and the problem is not visible. I think it is a problem with my network configuration. What should I look for to resolve this?

  • hadoop: port appears open locally but not remotelly

    - by miguel
    I am new to linux and hadoop and I am having the same issue as in this question. I think I understand what is causing it but I don't know how to solve it (Don't know what they mean by "Edit the Hadoop server's configuration file so that it includes its NIC's address."). The other post that they link says that the configuration files should refer to the machine's externally accessible host name. I think I got this right as every hadoop configuration file refers to "master" and the etc/hosts file lists the master by its private IP address. How can I solve this? Edit: I have 5 nodes: master, slavec, slaved, slavee and slavef all running debian. This is the hosts file in master: 127.0.0.1 master 10.0.1.201 slavec 10.0.1.202 slaved 10.0.1.203 slavee 10.0.1.204 slavef this is the hosts file in slavec (it looks similar in the other slaves): 10.0.1.200 master 127.0.0.1 slavec 10.0.1.202 slaved 10.0.1.203 slavee 10.0.1.204 slavef the masters file in master: master the slaves file in master: master slavec slaved slavee slavef the masters and slaves file in slavex has only one line: slavex

  • How can I use Windows Firewall to only permit the Windows Update service to make an outbound connection?

    - by microsmash
    I'm trying to tailor my Windows Firewall settings (using the Windows Firewall with Advanced Security console) to only permit programs that need to access the Internet with an outbound connection to do so. This works fine for normal applications as I can just allow the program, but services that load in the svchost.exe process are a problem. The only services I actually need to give access to are Windows Update and the Background Intelligent Transfer Service (and even that, I would only like Windows Update to be able to submit jobs to, but that's another issue.) Is there a method to only allow these to be permitted an outbound connection, and not any of the other services loaded in svchost?
