• Proxy authentication box not showing (sometimes)

  - by zerologiko

  I'm behind a proxy that require authentication by means of user/pass. I'm using Ubuntu 11.04, I think the proxy is "Squid". Usually everything works fine, that means that the browser shows me the window to insert proxy user/pass and I can navigate. The problem: Sometimes the browser refuse to show the authentication windows and if I wait enough it gives me an error like: Errore 130 (net::ERR_PROXY_CONNECTION_FAILED) Even if I restart, disconnect, the situation doesn't change. BUT on Windows the network (and the proxy) works.. So, bottomline what I know is: the network is working (though only on Windows) the Ubuntu configuration is ok (because i can navigate most days) The problems resolves itself in a few hours but I don't understand why. Some hints? Thanks in advance! Andrea

• atheros ar8161 not recognized

  - by Paul

  Apparently I am not the only one with this problem. This was my solution, but it did not work, of course. I downloaded the tar from another computer. I found the file of the atheros driver that I needed which is apparently atl1c. I put that file on my ubuntu desktop. I ran the following in the terminal: cd ~/Desktop atl1c make sudo make install I am sure that some of you will find this code laughable, but isn't there a simple code I could use once I have the atl1c folder on the desktop?

• How to set up router with DSL?

  - by NightwishFan

  I have a Verizon DSL connection. I am new to being the one who has to maintain the net. We have the Verizon modem and plugged into it is a belkin router. I did not alter the configuration on either of the devices. We get a net connection, though I have issues joining any form of online game. Some refuse to connect, others are slow. I have read that perhaps I need to use the modem in "bridge mode" to the wireless router? Would that fix my issues? Or do I just have to open ports or something similar. I really have no clue what could be the problem. Could someone advice me how to get this working with Ubuntu?

• How to direct a Network Solutions domain name to an html website hosted on Google Drive? [on hold]

  - by Air Conditioner

  To begin with, I'd wanted to take advantage of HTML, CSS, and so on to build a website that looks and works just as I'd like it to. I took a look around on how I could make that work, and I soon saw a lifehacker article showing that its possible to host website files on google drive. I then made sure that the folder containing the files was shared publicly throughout the web, and I now have a working 'google drive hosted' domain for the website. However, I did want to have the custom domain, and so I registered one with network solutions. So now, I'm curious on how I should direct my Network Solutions domain to the index.html I'm hosting on google drive. Would anyone have an Idea?

• Lag compensation with networked 2D games

  - by Milo

  I want to make a 2D game that is basically a physics driven sandbox / activity game. There is something I really do not understand though. From research, it seems like updates from the server should only be about every 100ms. I can see how this works for a player since they can just concurrently simulate physics and do lag compensation through interpolation. What I do not understand is how this works for updates from other players. If clients only get notified of player positions every 100ms, I do not see how that works because a lot can happen in 100ms. The player could have changed direction twice or so in that time. I was wondering if anyone would have some insight on this issue. Basically how does this work for shooting and stuff like that? Thanks

• How can I use smbclient to connect to Windows shares by hostname when a firewall is enabled?

  - by skyblue

  I can't connect to file shares on Windows computers using smbclient -L //hostname when the firewall is enabled. This occurs whether I'm using ufw (which allows outgoing traffic and replies back in with the default configuration) or iptables (where I'm allowing outgoing traffic and replies back in with iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT). However, smbclient -L //ip-address works whether the firewall is enabled or not. I also tested this against a Samba server running on Ubuntu and again smbclient -L //hostname does not work when the firewall is enabled, but smbclient -L //ip-address works whether the firewall is enabled or not. For reference, here are the iptables rules I used during testing: *filter :INPUT DROP [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -d 224.0.0.251/32 -p udp -m udp --dport 5353 -j ACCEPT COMMIT

• Cannot access windows share

  - by Wrigley

  I have an accounting program specifically tailored to the IT industry, its called Fincon (exe based). It basically works on a client to server directory base system. the server is currently running on a windows 7 machine with a NTFS partition. I have installed Wine. Have the shared Windows directory mounted with what I assume is the correct command for such being (mount -tsmbfs //servername/sharedir /mnt/fincon -0 usename=username,password=password). I can see the shared dir although it does take a bit long to access it on the Ubuntu machine via the mapped directory but instant via normal network browsing. I have also set up the mapped directory to my D: drive in Wine and have pointed the fincon.ini to read server field from D: directly. Here's my issue, it seems that for some odd reason I cant write to the mapped directory from Ubuntu, yet I can with my Windows machines, the permissions are set correct on the Windows 7 share and I really dunno what I'm missing. I'm quite a Linux noob just switched yesterday. Thanks guys for any help in this would be quite appreciated. As I'm pulling out my hair here and really want to migrate my work PCs to a Linux OS as it just gives less issues than Windows does ever.

• Network programming under windows: is WSA functions can be more complete than pSock functions [on hold]

  - by Kane

  I plan to make a set of classic socket functions to simplify their usages. Since i work under windows and linux indifferently i usually make it portable (it's not my first version of this set of functions), but i want to do something different this time and dedicate one version to windows, and one other to linux. With that i wonder for the windows version, if the WSA* functions can have any interest using them instead of the psock ones. I have found nothing about a comparison between them, so if any of you have any idea, suggestion, link or benchmark ?

• How do I fix my ethernet card losing network connection every few minutes with kernels 3.8.x?

  - by igoryonya

  I'm using Ubuntu 13.04. My laptop is Acer Aspire one 722-c58rr, and my ethernet card works for a few seconds at a time with kernels 3.8.x, however, kernels 3.5.x and below worked fine. On kernels 3.8.x, it works fine after boot for about a minute, then it looses network connection. When pinging to some address, it says: network address is unreachable, but it can ping it's own address. The address is statically configured. Everything was working fine before. I went to vacation, where I used WiFi and 3G connections, so I didn't notice that the problem occurred. Came back home, plugged in into the ethernet. It worked for a minute then stopped. Rebooting commutator fixed the problem. Tried to connect to a different commutator, same problem. Unplugging and plugging the cable fixes the problem for another minute. Disconnecting eth in Network manager and reconnecting it again, does the same thing. WiFi has no such problem. Tried to use a different cable that works fine on another computer, the same problem. Tried to boot with the lower kernel version, the same problem was happening until I got to the version 3.5 of the kernel series. Everything works fine on the kernel 3.5.x, but I don't want to miss out on the new kernel's features. Executing commands, when booted with 3.8 kernel series, give the following results: lspci| grep -i eth: 06:00.0 Ethernet controller: Qualcomm Atheros AR8152 v2.0 Fast Ethernet (rev c1) dmesg| grep eth1: [ 89.548291] atl1c 0000:06:00.0: atl1c: eth1 NIC Link is Up How do I fix it, while staying in the new kernel version?

• Cannot connect to wireless network

  - by smr

  I am quite new to using Ubuntu 12.10. All I remember while installing Ubuntu 12.10 was that I didn't check any box specifically to enable wireless connectivity. I tried looking into the various questions posted here - most of them refer to certain commands (redundantly sudo) and things of that sort. I am quite new and wasn't sure of understanding what those commands were trying to do (the network configuration settings - showed up different options, like 'Wireless', 'Wired', 'IPv4', 'IPv6' etc -- I am not sure of what sort of settings are to be made - like for example what sort of 'WEP' settings etc are to be made. Although I wasn't able to connect to the wireless network, I was able to connect to the internet, once I plugged in the ethernet cable. Can someone help me with: 1) Understandng a way to see if Ubuntu is configured to connect to a wireless network. 2) If so - Getting to configure to a wireless network (setting up a new one). 3) Where in ubuntu, should I look for seeing if there are any hardware devices (such as the Broadcom wireless adapter or things of that sort - like the way we use the 'Device manager' in Windows to look into the adapter settings). 4) Reference material to learn and understand the various ubuntu commands. (things like the -lshw etc).

• How often should multiplayer games communicate with the server?

  - by Bane

  I once heard that Runescape "ticks" every 0.3s, and that seemed like a very long period of time, although Runescape is kind of a slow game. I'm building a more dynamic top-down shooter game, and I'm wandering, how often should I communicate with the server? ASAP, or every 0.1s? How do shooter games usually do it? Both the server and the client are written in Javascript, node.js and socket.io are being used.

  This question already has an answer here: Correct way of mounting a Windows share 1 answer I hope someone can help me.. I'm trying to connect with my university remote filestore, but I can't make it work.. Here is explained what to do on Windows or Mac, and here I found a guide about how to do it with ubuntu, but it's not working to me (at the end of all the steps, I can't access to the mounted folder). I can access to the storage through Konqueror (I'm using KDE), but I would like to access to it also without it. Any suggestion?

• Adding a 'network' USB printer

  - by AndrewK

  I have a HP Deskjet 1050a printer, hence the 'network' in the title. Its a bog standard USB home printer. I have it attached to my router (has a USB port in it). I have got it connected and working to with Win8 PC and also a MacBook Air. Can't seem to get it to add as a printer to my Xubuntu laptop(s). It doesn't get detected automatically (not an actual network printer) and i've tried multiple options to get it working. It seems to add it but when printing a test page its saying the printer isn't connected. Ping works fine so it can see it, just can't add it as a printer. With Win8 I had to create a port with the IP of the printer (192.168.1.253 in this case), is there an Ubuntu alternative to do this?

• Windows recv method usage

  - by vandamon taigi

  I'm making a multiplayer game and I have an issue with the recv function ( or the send one , not sure ). Server side code : char* UserName = new char[256]; ZeroMemory(UserName,256); recv(sConnect,UserName,256,0); // works char* Password = new char[256]; ZeroMemory(Password,256); recv(sConnect,Password,256,0); // works users[ ++usercount ] = new Client(UserName,Password,sConnect); if( users[usercount] ->GetLogInSuccesful() ) send(sConnect,"0x0001",6,0); // debugging shows it gets here and sends the data. Client side code : send(server->getsConnect(),User,256,0); // works send(server->getsConnect(),Pass,256,0); // works char* Response = new char[6]; ZeroMemory(Response,6); recv(server->getsConnect(),Response,6,0); // gets stuck here. Any ideea why does it get stuck on that recv ? I also tried by making response [256] or such.

• Can't access some websites using Ubuntu 13.10

  - by Adame Doe

  Something's wrong with Ubuntu. Since I've upgraded to 13.10, I can't access some websites for no apparent reason. I've tried everything imaginable to solve this problem : Made sure that MTUs are the same, Disabled IPv6 in both the network manager and used browsers, Deactivated my network keys, DMZed my computer, Used other DNS like Google and OpenDNS, Checked that no firewall was running my computer ... And it's the same result. I even tried to reinstall Ubuntu a couple of times, but no luck. The most annoying thing about it is I can't access wordpress.org! So, there's no way it could be an ISP restriction of some kind. When I use a VPN, I can access pretty much anything. I'm really frustrated because I have to use wordpress.org very often. Any clue? ifconfig adame@adame-ws:~$ ifconfig eth0 Link encap:Ethernet HWaddr 00:26:18:3d:b0:7c inet addr:10.42.0.1 Bcast:10.42.0.255 Mask:255.255.255.0 inet6 addr: fe80::226:18ff:fe3d:b07c/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:8024 errors:0 dropped:0 overruns:0 frame:0 TX packets:7966 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:684480 (684.4 KB) TX bytes:616608 (616.6 KB) 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:65536 Metric:1 RX packets:8222 errors:0 dropped:0 overruns:0 frame:0 TX packets:8222 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:568269 (568.2 KB) TX bytes:568269 (568.2 KB) wlan0 Link encap:Ethernet HWaddr 00:19:70:40:85:eb inet addr:192.168.2.3 Bcast:192.168.2.255 Mask:255.255.255.0 inet6 addr: fe80::219:70ff:fe40:85eb/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1464 Metric:1 RX packets:123705 errors:0 dropped:0 overruns:0 frame:0 TX packets:98141 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:94963545 (94.9 MB) TX bytes:10387470 (10.3 MB) /etc/hosts 127.0.0.1 localhost 127.0.1.1 adame-ws ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters tracepath wordpress.org 1: adame-ws.local 0.092ms pmtu 1500 1: 192.168.2.1 1.300ms asymm 2 1: 192.168.2.1 1.060ms asymm 2 2: no reply 3: no reply 4: no reply 5: no reply 6: no reply 7: no reply 8: no reply ... keep on going like that ping wordpress.org adame@adame-ws:~$ ping wordpress.org PING wordpress.org (66.155.40.250) 56(84) bytes of data. --- wordpress.org ping statistics --- 10 packets transmitted, 0 received, 100% packet loss, time 9071ms

• Can't access windows 7 shared files on Ubuntu 11.10

  - by Corey

  I just set up ubuntu 11.10 and Samba. I got it to access shares on a Vista machine, but when I try to access the shares on a windows 7 machine it asks for a Username, Domain, and Password. I have no password set up on the windows 7 machine so I put in the username, and domain try to connect and the password prompt keeps appearing...also tried guest and admin with no luck...I've tried many different fixes(modifying registry entries & advanced securities on the win 7 machine) with no luck. Thanks

• Twitter "Authentication Error" Turpial & Choqok (latest versions)

  - by PineMarten

  I use Turpial a lot, but Turpial isn't connecting at all. I can still connect to Twitter thru the OS app (no issues signing in through Online Accounts) and of course I can still sign in using the browser, but Turpial gives me an "Authentication Error" and Choqok fails to do anything. I've tried changing my password, revoking the Turpial and Ubuntu apps in Twitter and re-enabling them, but then it gives me an "Invalid Credentials" message. I've even removed and installed Turpial multiple times, still nothing. I can't find any information or resources for this type of error from Turpial online. I think it may be something recent after finding this message elsewhere: (article related to "Birdie") It looks promising i'm currently using it atm, since all the other twitter clients no longer work due to the API 1.0 shutdown (posted today) I've never used Choqok before today, so I don't even know if I've set it up properly. It's failing to retrieve or send Tweets it just blank screens, but at least it signs in. I've figured that this isn't an issue with Ubuntu, or Turpial or Choqok, or the router (already replaced it today), so I don't really know what I'm dealing with here. I hope it's not another API issue, Facebook did something similar just a few weeks ago

• Ubuntu 12.04 - no wireless network recognized

  - by Itai

  I just installed Ubntu 12.04 along with WIN7 on the same laptop - Dell Vostro-3560. Now, on Win7 i can access to different wi-fi networks. However, when i am logging onto the Ubuntu section (after re-starting my laptop) - an error message appears: "Disconnected - you are now offline". When i take a look at my network menu (in the upper bar on the screen), i see that no network is found (and i have a few of them in the area...). I tried to look around but really could not find a concrete practical solution to this specific problem, would appreciate any solution from anyone out there that had this problem and solved it. Thanks... Itai

• Need a few reboots to connect to wireless

  - by Debajyoti Nandi

  I am running xubuntu 12.10 on my msi wind U100 netbook. I have a problem with the wireless connection. Whether the wireless connects automatically to a known wifi hotspot (both at home and starbucks) is temperamental. Sometimes I need to reboot one or more times to get it connected. Otherwise, it tries and keep asking me to enter the password (which is saved and when it works it does, so the problem is not with the password). Every time my computer awakes up from sleep the same problem. I have to do a reboot to connect to wireless. I searched everywhere but found no solution. I would greatly appreciate if someone has any solution. I will gladly share the hardware/software or config info, if asked, but I don't know exactly what to share and where to find them. Thanks you for any help.

• What data-structure/algorithm will allow me to send a list of key/value dictionaries using the least amount of bits?

  - by user12365

  I have server objects that have corresponding client objects. The data to be kept in sync is inside the server object's key/value dictionary. To keep the client objects in sync with the sever objects, I want the server to send the key/value dictionary every frame for each object. What data-structure/algorithm will allow me to send a list of key/value dictionaries using the least amount of bits? Bonus constraint 1: For each type of object, the values of some keys change more often than others. Bonus constraint 2: Memory usage on the server side is relatively expensive.

• Unstable wireless connection on Ubuntu only (router config problem?)

  - by crunch

  so I'm using Ubuntu 14.04 and I could connect to all Wi-Fi's that I've tried and it worked fine... Except for this router that I have at home. This connection seems to be unstable, it just randomly disconnects and reconnects. On the same machine I have Ubuntu 13.10 (same problem) and Windows 8 (no problem). Also there are no Wi-Fi problems when I connect with my Android phone. So I figured it must be some config issue. I tried tweaking some settings/restoring default on the router but I don't really know what I'm doing so, unsurprisingly, it didn't fix the problem.
