Networking :: BSD Super User 4015
Mar 18, 2011
I have an old Toshiba Satellite 4015CDT, with Pentium II MMX, 32MB RAM, 4GB HDD. It also has one USB 1.0 port, parallel and serial ports, a 3.5" floppy drive and a CD-ROM drive (probably almost dead). I've installed NetBSD on this machine (full install) and now I want to connect it to the Internet. Although it has one PCMCIA modem card in it, it is obviously not an option.
I've narrowed down my available options to the following:
Connect a USB wireless adapter. I have a Realtek RTL8192U adapter, but although the system gives me the device's name (through dmesg) it fails to recognize it as a network adapter. Connect the laptop to another machine through a serial connection, so that the other machine will serve as a bridge to the Internet. Here is the page from the NetBSD documentation on serial connections. Unfortunately, I was not able to find anything on bridging there.
Status update: tried installing a driver for my adapter using NDISulator on NetBSD. However, the kernel compilation failed. See here.
Status update #2: tried installing using NDISwrapper on Damn Small Linux (kernel 2.4.31). Although the driver installs and ndiswrapper -l shows hardware is present, I cannot configure the network interface (doesn't show up in ifconfig -a and iwconfig). It seems like this adapter is not supported by NDISwrapper (at least it's not mentioned on their wiki.

I just got a new laptop, and for the most part have left its settings alone. Today I was trying to get some sharing going between my desktop and the laptop. Both machines are connected to the same wireless network and both machines consider that network to be a Home network. Both are running Win7 Home Premium. It seems like my laptop is aware of my desktop on the network. It can ping it by IP or by computer name. When I go to Network from the laptop, I can see the desktop in the list of computers. However, my desktop cannot ping the laptop, nor can it see it within Network. My desktop has a Homegroup set up, but my laptop says "There is currently no homegroup on the network". I do have network discovery turned on for both machines. Why can my desktop not "talk" to my laptop but it works the other way around?
Update: Disabling the Windows Firewall on the laptop somewhat fixes the problem. With it disabled, my desktop can ping my laptop, but still my laptop can't see the homegroup. Also, it can ping via hostname, which resolves to IPv6, but can't ping via the IPv4 address. Obviously I'd rather not leave my firewall disabled, so I need a more specific fix.
Update 2: Aha! It is the Cisco VPN software I was running to connect to work computers. Once I disconnected and exited from that, the two PCs seemed to be talking normally and the homegroup was visible to the laptop. So now my question has morphed: how can I prevent Cisco VPN from interrupting my home networking?

I'm building my own home server based on Ubuntu with 4 drives in RAID 10. Its primary purpose will be NAS and backup.Would I be making a terrible mistake by building a NAS Server with a single Gigabit NIC?
I know the absolute max I can get out of a single Gigabit port is 125MB/s, and I want this NAS to be able to handle up to 6 computers accessing files simultaneously, with up to two of them streaming video.
With Ubuntu NIC-bonding and the performance of RAID 10, I can theoretically double my throughput and achieve 250MB/s (ok, not really, but it would be faster). The drives have an average read throughput of 83.87MB/s according to Tom's Hardware.
The unit itself will be based on the Chenbro ES34069-BK-180 case. With my current hardware choices, it'll have this motherboard with a Core i3 CPU and 8GB of RAM. Overkill, I know, but this server will be doing other things as well (like transcoding video).Unfortunately, the only Mini-ITX boards I can find with dual-gigabit and 6 SATA ports are Intel Atom-based, and I need more processing power than an Atom has to offer.
I would love to find a board with 6 SATA ports and two Gigabit LAN ports that supports a Core i3 CPU. So far, my search has come up empty. Thus, my dilemma.Should I hold out for such a board, go with an Atom-based solution, or stick with my current single-gigabit configuration?
I know there are consumer NAS units with just one gigabit interface (probably most of them), but I think I will demand a lot more from my server than the average home user.

Is this a good price *NEW* for this unit...325.00
NEW SEALED* Cisco ASA5505-BUN-K9 Firewall 10-User
I assume 10-user means this device comes with a 10 user VPN license? Is there anything else I should be looking for when purchasing an ASA? Mainly looking to use my NetGear WNDR3700 as just a WiFi AP and not my edge device.

Internet VERY choppy on one computer, has happened on more than one network, both wireless and wired. I've even reinstalled Windows 7 on the machine from scratch the problem is still there.The internet goes VERY slow like 10 minutes a page sort of slow. Almost feels like its being choked but from what i can see theres no programs taking bandwidth etc.I've searched all over the net and can't find anything. I can give any information needed.The machine is currently on wireless but the wireless signal is great as i use other device on it in the same area and there perfect.

Normally use internet explorer 9, but I've tried Firefox and Chrome also.For some weird reason the Wi-Fi on my computer is super slow. My roommate has no problems at all. Same issue when only one of us are connected. What's really weird is that it's only on my home network the speed is a problem. At school and at other family members houses everything is working perfectly. I now use wired internet connection, and when I take a speedtest it is around 13MB, so the speed is pretty good.
I can mention that sometimes if my computer has been closed and the cable is taken out, when I turn the computer back on the Wi-Fi is suddenly working perfectly. Only for a while though, and then it's not working anymore. Has happened more rarely recently.I've been having this problem for around 7weeks now. When I first discovered the problem I tried to uninstall the latest updates (among windows updates), and it actually worked. But I want my computer to be up to date, so it's not a go to use those settings.
I have tried to reset the router to factory settings, but that did not work.We share internet with our landlord, so to privatize what we do, it's set up like this: Landlords modem -> switch in our apartment -> wireless router But that should not be problem. It's working on everyone else's computers. My mobile phone as no issues either;I've tried to update the driver on the wireless card, but it's up to date.

I had my Dir-655 router for over a year & this is is a first.My firmware is 1.21 & I only use my router for gaming when I'm not on my PC for home use. I have only one PC in the house that is not shared, I have also not downloaded any virus or maleware.So the past month I decided to buy a wired ethernet cord to connect to my gaming systems rather than using the wireless option to get an extra bit of speed. That has been working fine up till yesterday when all of a sudden my download speeds dropped from around 20Mb down to barely 1Mb down (I can't even get the speed test site to fully load anymore). The upload & ping remains unchanged though. Only my Download speed is being affected. This is both when I'm on the PC & when I'm online gaming.
I unplugged my D-Link router & plugged my modem directly to my PC & I got back the 20+Mb speed, so the modem or cable company are not at fault (I even called them to see if there were any problems on there end).
-I tried turning off my Firewall on my PC.
-Resetting & rebooting both my modem/router/PC.
-using different DNS numbers.
-using /flushdns.
-using /Iprenew.
-Messing around with my router configurations such as:
turning off QoS Engine.
turning off wireless.
turned of MAC filtering.
unchecked "Add DHCP Reservation".
unchecked SIP.
None of it worked. I'm still browsing at around 56k dial up speed for the past day+!I read up on the internet for similar problems, but the only solutions I saw was turning off the firewall on the PC, but that hasn't worked at all.

I used the ASA 5510 and in these days, facing the problem is internet is very slow. When i check in real-time log viewer debugging, i found the following logs 6|Jun 29 2011|15:47:53|106015|123.123.123.123|416|111.222.111.222|80|Deny TCP (no connection) from 123.123.123.123/416 to 111.222.111.222/80 flags ACK on interface Inside 4|Jun 29 2011|15:47:53|106023|123.123.123.123|852|111.222.111.222|80|Deny tcp src Inside:123.123.123.123/852 dst Outside: 111.222.111.222/80 by access-group "Internal_access_in" [0x0, 0x0] a lot of log message are come out and I notice that 111.222.111.222 ip is try to attack my network. In that moment, my network is very slow and nearly to be down. When I block with that ip by access list, network is up again. But after a few moment, attack from other ip, it's so terrible and so tired to block a lot of ip by acl.

Been catching wind of an upcoming super fast router....the Asus RT-66U.Currently their RT-N56U has been the fastest router tested at smallnetbuilder....at over 800 megs throughput.The new RT-66U has a 600MHz processor, and 1 gig of RAM. State table size (concurrent sessions) at over 300,000.
Supposed to be based on the Broadcom chipset..so it'll probably support DD-WRT...but to be honest, I saw some screenies of the Asus firmware for this unit...and holy crap what cool features.url...

My E1500 worked perfectly before. Today CiscoConnect notified me to upgrade my router. After I've done that, the wifi connection speed is super slow. But when I use hardwire to connect, the speed is as fast as before

Just upgraded my E4200 to firmware 1.0.03 (from 1.0.01). I have some new issues, questions, and some outstanding issues.
1) Web interface over https is now painfully slow.
2) Does DDNS work in bridge mode? DynDNS allows the sending of an update without an IP address, so it should be able to work.
3) Does accessing the management interface in bridge mode count as local or remote?
4) I'd really like to be able to get WOL working through the router. I managed to create a static DHCP reservation for 192.168.1.254 to ff:ff:ff:ff:ff:ff, but I don't think the router added that entry to the ARP table, is there any way to do this.
(I think have WOL forwarded to 192.168.1.254). 5) Should the router be providing some local dns hostnames? For example I have the device name set up in the local network setup, but it won't resolve. Similar for connected devices, especially those with with a DHCP reservation. 6) In bridge mode, does it matter which port is used to connect to the other network device? Does it have to be the WAN port?

For the past year my wireless has been working great and I have being playing games/doing homework with no hassle. Yestetday my internet connection became very slow. After countless restarts, router/modem resets nothing has changed and I only get like 5kb of download speed. Since my internet connection was lost naturally I unplugged the wireless card and re-plugged it, didn't change anything. After that I restarted my computer, but nothing changed. AFTER THAT I unplugged my router, then reset my router to factory settings, which did not change anything. Since everything was backed up I thought I would reinstall Windows 7 to nuke any hidden problems. After 2 reinstalls of Windows 7, nothing has changed. Next I had Comcast reset my connection with them which did not work. Though it did work with my brothers desktop. After some more time just fiddling around my connection went back to lightning speeds. no.....4 hours later my connection went dead.At all times my computer will see my network but it either will not connect to it or it is really really slow now.

Two computers (XP and Win7) connected on office LAN, cisco 2960, not same switches, but all in the same rack, and link togeter, same IP subnet, tried to copy some kind of 26G files from one to another, using Windows share folders, and it showed need 23 hours to finish the copying.It's not the first time, actually we always experienced very slow speed when copying files on Windows share folders. Did not see any particualler message on the switch. ports are all full/100m.

I recently installed a very basic version of XP on my old laptop (Gateway MT3707).After hours of searching for the correct drivers, I found them, and installed them. After installing the correct drivers for wireless internet I was able to pull up the list and find my network on it.When double clicking on our wireless network it asks for a network key (also called WEP key or WPA key).Now we have a password for our network, but after an exhausting amount of tries that won't work. I not sure if that is what its looking for. In our apartment we run mac OSX, windows vista, etc., but usually the password for the network is satisfactory. I have never ran into this problem.I hate to be a noob, but I don't know where to go from here.

We are using an ASA 5510 and remote access (SSL VPN) using the AnyConnect client.
Is it possible to display a user message when a user connects using the AnyConnect client, matching a specific dynamic access policy? Can the message be displayed when the action is "Continue" rather than "Terminate"? I can't seem to get this to work and wondered if there was a LUA function to do this.
We have a DAP which gives a restricted ACL when the user's anti-virus is out of date, and I wanted to notify the user to update their anti-virus and reconnect.

Having some serious problems on the networking front here at home. I have 3 PC's and 2 Xbox's that run constantly. Our Internet bandwidth is Insight's 50.0 which is 50Mb download speed 5Mb upload speed. The problem we're having is this. Ever since we upgraded from dual 20Mb lines on a Cisco RV042 to a 50Mb on a DIR-655 we've been having latency issues. I have everything turned off in the router. It's basically there to give out IP numbers and thats it. All security is handled from the PC's themselves. Bandwidth tests are fine, I sustain download speeds above 7MB/s using download managers. But pings are terrible. Xbox live is terrible, PC online gaming is terrible. Pingtest.com is terrible. Only when behind routers. I've tried it behind 3 seperate routers. The DIR-655, the Belkin f5d8236 that insight provided me, and the cisco rv042 originally used for dual wan routing. all of which are met with serious failure.
If I plug directly in to the modem pings are fine. Add a router and pings go to shit.

My laptop (Win 7 x64) can currently access all the shares on the XP computers in my home network but,although I can see it, I cannot access the laptop from my main xp computer. I haven't tried to access it from the other xp computers downstairs. I have read the guide on this site as well as 3 or 4 other threads on this subject but am unable to resolve the issue. Completing the network setup so that I can look into my laptop from this main xp computer. My laptop has a wireless internet connection but I also have it plugged into my wired home network for sharing. I will provide other details as needed. I suspect that some essential services for file sharing may not be running on the laptop, but I'm not sure.

I have been looking at ways of networking my printer in my office. The problem being that my printer does not have any kind of inbuilt networking capacity.So I thought I could connect it via USB to my router as it has a USB port on it.The router is an Orange Bright Box - In the specs for the router it says that the USB port is for file sharing, mentions nothing of connecting a printer to it

Trying to network between a Windows 7 computer and a Windows XP computer is possibly the hardest thing I have ever done.I have googled for hours and hours and none of the solutions seem to be working.I will try to explain what I have already done. Although I have done loads and I am sure I am missing some things.I have a Windows 7 laptop and for this exercise I shall call it WIN7. I have a Windows XP computer and for this exercise I shall call it WINXP.Both computers are in the same network which I have called SAMNETWORK. I have enabled permission to Everyone in folder sharing settings on WIN7. I have turned on Sharing and I have made myself discoverable with no password set on Network and Sharing Advanced Settings. Both user accounts on the XP and 7 machines are the same and both passwords are the same. I have turned all firewalls off. The WINXP computer has sharing enabled.
I have done a lot more things including installing LLTP (sp.?) and changing registry entries like Lsa/anonymous something like that (can't remember the actual directory) but I have changed registry entries as I have read elsewhere on the web and I have changed the network from home to work but that did nothing etc. etc. But everything that everyone suggests is just not working and I have been looking for about 4 hours now so you can imagine I have tried everything I have found!Anyway, my 7 laptop can see WINXP but when I click on it, it states that Windows cannot access \WINXP. The WINXP computer can see shared folders from WIN7 but it also states that it is not accessible. However, I did once get the WINXP computer to access the WIN7 shared folders. However, that doesn't even work now. I need the WIN7 to access the WINXP files. [code]

Running Windows XP Im a bit Dizzy as i can't seem to workout what's going wrong or what im doing wrong lol!!!8 Pc's on the network, all can view files etc.apart from one Pc Lets just call this "Bob1"It keeps asking for user name and password, now there's no user name or password on the giving pc, file and sharing is open and all the right ports giving. what i can't understand is that the reaming 7 pc's on the network has the same setup and files permissions, on the same subnet and can ping each other to my knowledge.So just to prove myself wrong i made a password for the pc that was asking for one on the network and this still did not work.so to cut the story short 7 pc's can search each other fine but on "Bob1" keeping asking for user name and password.

networking error which seems to make no sense to me, i have computer 1 (tower computer) computer 2 (laptop computer 3 (tower computer1 & 2 have networked happily together for 4-5 years, sharing files and printers both ways. 3 was connected and happily joined the network but only with 2. 1 can see files on both 2 & 3, have now disconnected 3, have reset and rebooted router and both computers are up to date with software patches, i can not work out why 2 (or 3 before it was disconnected) can see 1 on the workgroup but can not access 1 in any way. i can, however, copy a shortcut from 1 through metwork places into 2 and access those files from 2. but network wizard or manual setting can not get full sharing.

I am the CEO of a small company with 5 divisions, 2 of which are remote. There is also my home office that I wish to be on the company VPN.We can't afford an IT department, so it is up to me to ask for a network diagram (as specific as possible) that lays out all the hardware required.My plan is to eventually have an intranet web server, file server, and database server all for internal use. Our external webserver is hosted by a well-known company. Growth must be considered both in hardware and network.

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.

this is crazy - when i came back from out of town i tried to see if my problem still existed. it did - the win 7 laptop still could not "see" the win xp computers on the home network but all of the xp computers could see the win 7 laptop. just before sending this reply, i tried it "one more time". wa-lah, the laptop can see the other computers. this happened once before, it was seeing them, i had to leave the system and come back the next day - when i came back, the problem had returned. i did notice when i came back from out of town, my power had gone off and came back on- but this was b4 i checked it only to find the problem was still there, as just mentioned, i tried it just b4 writing this reply and the problem was no longer there. i just rebooted the laptop and as we speak, i can see all 3 of the xp computers from the win 7 laptop. i really can't make any sense out of what's going on but am beginning to think its in the modem.
