I have connected fax machine with line card, line card with Modem (MT5656SMI), and with modem is connected to PC UART. i want to pause the fax machine from PC, while scanning. i gave AT+FTS=10 command. but it did not worked.
I am having issue on my 3750G gig interface, it is not passing data more than 200M.Some how its giving me lots of input Pause on both sides,can some one explain if there is congesstion issue,do I need to enable flow control on both sides? [code]
I have a strange error on my home network that I cannot find a solution to.I have an Huawei SmartAX MT882 from TalkTalk acting as a modem connected to a D-Link DSL-G624T acting as a router/switch. Connected to the D-Link I have a Windows 7 Pro machine (64-bit, SP1) and an XP (home i think) machine (sp 2 i think).The SmartAX modem is set up to perform DHCP and DNS relaying and the D-Link has DHCP turned off and DNS relay turned off.The Win7 machine can access the network, get an IP address and access the internet without problems, regardless as to the status of the XP machine.The XP machine can access the network, get an IP address and access the internet with no problems ONLY of the win7 is powered up. When the win7 machine is off, the XP machine seems to drop about 25% of the ping packets between it and the D-Link router and has no internet access (because of this i assume). [code]
New Win-7 machine set up. I used the printer set-up wizard to install a networked printer in the new machine with absolutely no problem. Proved it would print from that machine.Now, I get a call informing me that her old XP machine, which had been printing to the network printer with no problems, will no longer print.Documents go into the print queue, but they don't get printed.No error messages show up.I did some messing around via remote access, and finally removed the printer with the intention of reinstalling it.Scanning for network printers turned up several redundant instances of the same printer with different names. Some are identified as "invalid" some a "access denied". Bottom line. I can't get any of the selections to install.On the Win-7 machine I did find a window that indicated that the printer is designated as being shared, but I didn't explicitly set it for sharing when I installed it. Also, I somehow got to a window that told me that for printers that were to be shared with other versions of windows I could optionally install drivers to support such machines. Didn't have the driver disk handy and took the window down. Now I can't even find it again.I need sorting this all out.Part of the problem is that out there in "network land" there are redundant remnants of previous installations that are being remembered inappropriately.
There are three Win 7 laptops on the LAN trying to connect to the ASA5500 Firewall. They generate a Severity Level 3 alert and try the same port three times then move to the next numerical port and try that three times. Is this a malicious Hack.
My company deals in a video conference software which requires certain ports to be open to work correctly, including tcp and udp ports. Clients who want to test / purchase have different kind of network setup. I usually tell them to open those ports require by the software on their end. How do i ensure if the port range required by my software is open once I am at their location. I have installed a few network scan tools but not sure what ip do i scan. Should I scan my server's ip once I am at their location and connected ? or should I scan their gateway ?
i have a Edimax usb adapter Ew 7612HPn which is brand new, & its not scanning any networks though the light flashes fast, i tried on both my & my dad's laptop, & same problem.Also tried different Usb cables still the same, but sometimes it worked, but mostly dosn't work.Kindly note that i am using this on my vaio Cr 354 windows vista 32 bit SP2 home premium.From day1 it was like kind of faulty, i mean it worked but kind of disconnected in between, but now it dosn't work at all just keeps flashing the blue light.
the setup is as follow: I have two separate network.192.168.90.xx and 10.10.xx.xx the two boxes being connected via an ethernet cable. How would I go about having a 192.(...) machine speak to a 10.(...) box? My boss tells me that via a UDP call the 192.(...) machine can get the IP of a 10.(...) box. Isn't UDP dependant on a subnet mask to limit the # of queries, and in that case would it even be feasable? I was thinking instead of spoofing the 192.(...) IP to an unoccupied 10.(...) IP. Of course to do this would require knowing what IPs are unoccupied on the other network, and I cannot assume the would respond to pings.
I am running a DIR-825 I believe one of the original's no updates or anything. I run it mixed mode. The 2.4 shows up and I can connect to but the 5 ghz (n) speed says it's enabled but I can never see it when I scan on any of my wireless n products (laptops and other computers). Dlink support told me to change to mixed mode g and n. I was running it in mixed mode (a, g and n). D link told me to change to mixed mode g and n and to make sure they stay on channel 6 and 11. Is this correct. Which firmware should I upgrade to and is there any easy way to do this?
I have a network problem. My windows 7 machine is not detecting win xp machine whereas win xp machine is detecting win 7 machine. They are in the same workgroup named Home. And the networking system is set to work. I have left the homegroup I was previously in. I enabled file sharing for devices that use 40 bit and 50 bit encryption. On XP I have enabled NetBios over TCP/IP. File sharing is enabled on both computers. I think it's something obvious as both instalations on different computers are really fresh and both windows haven't been tampered with.
url...I discovered that it would be possible to be protected from portscan, i mean when someone scan our nework/host from outside, the attacker will see all the 65535 ports as "open" (in that way it will be more difficult for an attacker to perform customized attacks...)So I have follow the setup in that link: policy-map global_policy class class-defaults set connection embryonic-conn-max 15 per-client-embryonic-max 3 service-policy global_policy global . The problem is that I don't have the exepected result..If i do a portscan over Internet from an external host to my hosts the portscan is successfully working and I can view my open ports...I have also tried to set this through a "match" in an access-list but without any sucess.
I want to install a windows operating system in my machine but my machine dont have a CD-ROM. so i want to install an OS from using my another PC(Laptop)'s CD-ROM. So is it possible to install OS into my one machine from another different machine(windows-7) via sharing the drive .
I am trying to configure a NIC IPv4 with IPv6 disabled on a virtual machine (win server 2008)The instructions I got say that I need to use IP 192.168.210.0/24.However when I enter this IP and use subnet mask 255.255.255.0 I get the following error. Why this is and if there is a way to resolve the error?
I am working on a project at my company. In short, there is one PC in the office to which other user must remotely connect to perform certain tasks. The stuff they do must be done from the machine with the specific IP, the IP of that machine, as this is specified in agreements with the companies we work with. So far, we have been using Remote Desktop (our machines are Windows-XP-based PC's), but this is quite annoying when more than one person needs to use the machine at the same time
I am trying to link a Windows 7 machine with a laptop running Windows XP. The workgroup on both computers is the same. On the Win7 machine, I have a couple of folders set to be shared. The first is the C Drive and the share name is C-drive. The second is Quickbooks that I have named Quickbooks. On the XP machine, I went to map network drive and in the blank typed \Remote1C-drive. It asked for username and password and just like that we were connected. But I can't see all of the files on this drive. I don't even see all of the folders - one of which is Quickbooks. So I tried \Remote1Quickbooks and Windows XP couldn't find that path even though I'm positive that folder is shared on Win7. So no matter what I try, I can't see this folder on the XP machine, I even tried copying this folder to other locations around the computer and setting up shares in hope that something would work, but it never did. So I went back to the C Drive share on the XP machine. I tried to go in reverse, creating a file and putting it on the root of the c drive (I did this on the XP machine, but the file should have actually been located on the Win7 machine. When I check Win7, the file didn't exist. So I tried the other way. I right clicked on the c drive in Win7 and created a new bitmap image file. Back to the XP laptop, that file doesn't show. But if I look at the c-drive on Win7 from the xp machine, I see several other folders and some of them like Program Files contains actual files. But some of them are just empty such as \Remote1C.
I have two routers in my office, each one having wireless extensions and its own DSL connection.I want machine on A subnet communicate with machine on B,I'll need some sort of physical connection (a cable? a new device?).Router A and B are typical home router with wifi extension: they only have a WAN port,I won't be able to let them talk to each other simpy by plugging an Ethernet cable between two LAN ports, since the two routers are on different subnets.
Basically, I am swapping my Atom/ION nettop (that I use as a file server, game server, torrent server etc. etc.) for one that has no fans and no mechanical HDD. I control it primarily via RDP, so I don't need to plug a keyboard or display into the nettop itself.
The new one I'm getting should be a step up due to the whole no moving parts thing, as well as the much faster CPU. But Intel, in their infinite wisdom, have not provided (and don't plan on providing) a 64bit graphics driver for the GMA 3650.
If I were to install 64bit Windows on this new machine without installing a driver for the graphics, would I have any issues using RDP? I'm not sure if the visuals are generated on the host or the client and whether it would matter either way.
I have two Win XP machines and a Linux Mint. I can access the shared folders of my Win machines from Linux but Win machines, in the Workgroup, shows the Linux connection as "MyMint server (Samba, Linux Mint)(MyMint)" but I can't access files on that machine. "MyMint" is the computer name.
I have a Windows 7 machine connected to my TV set. I want this machine to act as much as an appliance and as little as a PC as possible. To that end, I want it to be able to access my NAS disk, but not the Internet. Internet = annoying update messages (think Adobe), viruses, crap.I don't know if this is a setting that I can do in Win7 or in the DI-Link AirPlusG router thing
I have 2 NIC cards on the same machine running Redhat 9.I need to setup the machine in such a way that both cards are in the same subnet but card on port eth1 can be reached through card on port eth0.I tried modifying the iptables (with the limited knowledge that I have on it,used google) and even tried turning it off.I also tried setting files /proc/sys/net/ipv4/ip_forward and /proc/sys/net/ipv4/conf/all/proxy_arp to 1 but was unable to ping from IP address on port 0 to IP address on port 1 and vice-versa
Everything in the house can connect to the internet aside from my windows 7 machine. It was working fine acouple days ago. it was connecting via a wireless network adapter through a USB. I tried switching the USB ports, hardwiring, re-ownloading/installing the drivers and even reformatting the machine. i still cannot get an internet connection. Only logical thing to do would be to replace the NIC ?
I have set up an ACS (5.2) to do EAP-TLS Machine and User Authentication.I am getting intermittent results with the machine authentication using the same laptop as a test client.When the machine authentication succeeds the RADIUS name shows as host/xxx-yyy.When the machine authentication fails the RADIUS name shows as xxx-yyy without the host/.
I know a ip from a thing without being connected? I'm working yhe.. now I can't access physical to pc because its implanted in some officce wall but i knwo its log on in net service... the only thing i want its to find the ip from it like magic I dont know
I am running 802.1x using a cluster of ACS 5.2 appliances and Windows XP hosts using EAP-MSCHAPv2 over a PEAP tunnel.The PC are set to perform machine authentication and if authentication is successful,they are mapped to a specific VLAN based on their AD group memberships.The problem that I am encountering is when the machine password expires while a user has their laptop off the LAN. When they bring the laptop back to work and put it on the LAN, authentication fails and the laptop does not run through the authorization policy to determine what action to take. Looking at the microsoft site, I found this:
This basically states that Microsoft is aware that Windows XP is not able to change machine passwords on login after the expiry period. They offer two solutions for a workaround:
1. Use EAP-TLS - I don't want to use certificates for machine authentication due to PCs dropping off the network when they are renamed due to the PC name on the certificate not matching the PCs actual name
2. Perform user based auth - Windows XP doesn't pause the netlogon process during bootup, therefore if the user VLAN changes when user authentication is performed, all statup scripts will fail.
This brings me to trying to perform a workaround directly on the ACS appliances after authentication fails.I have an access service setup that matches any machine authentication packets from PCs configured for machine based authentication.This service then maps the VLAN upon successful authentication. Since the authentication will not be successful, the process will fail before getting to the authorization policy.I have looked into forcing the policy to continue upon failure, however this advanced option is not available for PEAP authentication.Now,I am trying to determine if there is anyway to perform VLAN mapping for a host that fails machine authentication using a rule based result selection on my identity policy for the machine authentication, but this is not working. There really needs to be a way to force a policy to continue processing even when authentication to the domain fails for PEAP authentication.
I manage the network of a small (120 users) network spread out over 5 sites within a 10 mile radius (for normal ops- extended ops can expand to include other cities).I think I'd call that a Campus LAN, perhaps it's just a really small MAN (for normal ops)...I am starting my CCENT/CCNA track so this may be blazingly obvious to some of you- but I'm sure to learn something either way...Every now and again we have to go find "hostname "X"" for an update that won't roll out by way of our (Server Sr SysAdmin's) tools, so we actually have to put hands on it. Unfortunately the prior admins didn't document the inventory to such a level that we know "laptop_015" is in the building down by the college.
I DO have documentation on my equipment (I'm the Network Sr SysAdmin) that I have rolled together over the last 9 months being here...I have a Cisco 5520 ASA, and use ASDM to manage it. What would be extremely handy would be the ability to put a query in the system to report back what switch a given hostname is plugged intoBetter yet, if it could tell me switch and switchport.I imagine this would be simple if I had the MAC address- there's got to be a way to grep the switches for a given MAC- but not sure if it'll work in a similar fashion for ARP lookups.
I have a PC behind a DSL router. In my PC (WinXP SP3) I have a virtual machine also running WinXP SP3. I would like to access the VM via remote desktop. Since I have a dynamic IP, I use the(url)tool to solve the problem. I installed the no-ip sync tool in the VM. Now when I write my no-ip address in the remote desktop from my office, I will access my host system, and not the hosted VM. Does any knows how I should configure things in order to get access to the virtual machine and not to the host machine
My home network, consists of a bunch of Win 7 computers and 2 XP machines. One XP machine is a netbook, it's rarely on and presents no issues.Here's the problem I'm having with the other XP machine:-My Win XP PC does not show up in the list of networked computers on any of the other machines on my home network.-But I can still access the shared folders by going to start and typing in \computer name.Win 7 will open a folder containing all the shared folders and I have no problem accessing (and modifying) any of its contents.-I also can access the PC via a VNC client set up on another machine and even have ports properly configured to access it from out of the house-I use this PC as a server to stream music to my iPhone via subsonic. No problem here either-I can access all the other computers from the XP machine in question.Since I can still get to the files this wouldn't be a big deal, except:-I can't map a network drive to the XP machine from the other PCs and I need to-I have an HTPC computer whose software can't find this XP machine because it's not there
