  • I can't add PPA repository behind the proxy (with @ in the username)

    - by kenorb
    I'm trying to add the ppa repository (as a root) with the following command: export HTTP_PROXY="http://[email protected]:[email protected]:8080" add-apt-repository ppa:nilarimogard/webupd8 Traceback (most recent call last): File "/usr/bin/add-apt-repository", line 125, in <module> ppa_info = get_ppa_info_from_lp(user, ppa_name) File "/usr/lib/python2.7/dist-packages/softwareproperties/ppa.py", line 84, in get_ppa_info_from_lp curl.perform() pycurl.error: (56, 'Received HTTP code 407 from proxy after CONNECT') Unfortunately it doesn't work. Looks like curl is connecting to the proxy, but the proxy says that Authentication is Required. I've tried with .curlrc, http_proxy env instead, but it doesn't work. strace -e network,write -s1000 add-apt-repository ppa:nilarimogard/webupd8 socket(PF_INET6, SOCK_DGRAM, IPPROTO_IP) = 4 socket(PF_INET, SOCK_STREAM, IPPROTO_TCP) = 4 connect(4, {sa_family=AF_INET, sin_port=htons(8080), sin_addr=inet_addr("165.x.x.232")}, 16) = -1 EINPROGRESS (Operation now in progress) getsockopt(4, SOL_SOCKET, SO_ERROR, [0], [4]) = 0 getpeername(4, {sa_family=AF_INET, sin_port=htons(8080), sin_addr=inet_addr("165.x.x.232")}, [16]) = 0 getsockname(4, {sa_family=AF_INET, sin_port=htons(46025), sin_addr=inet_addr("161.20.75.220")}, [16]) = 0 sendto(4, "CONNECT launchpad.net:443 HTTP/1.1\r\nHost: launchpad.net:443\r\nUser-Agent: PycURL/7.22.0\r\nProxy-Connection: Keep-Alive\r\nAccept: application/json\r\n\r\n", 146, MSG_NOSIGNAL, NULL, 0) = 146 recvfrom(4, "HTTP/1.1 407 Proxy Authentication Required\r\nProxy-Authenticate: BASIC realm=\"proxy\"\r\nCache-Control: no-cache\r\nPragma: no-cache\r\nContent-Type: text/html; charset=utf-8\r\nProxy-Connection: close\r\nSet-Cookie: BCSI-CS-91b9906520151dad=2; Path=/\r\nConnection: close\ Maybe it's because there is @ sign in the username?

  • How to increase signal/range of your Wi-Fi antenna-less repeater/booster over the network?

    - by kenorb
    I've BT Home Hub in the upper flat (2-3 walls behind) and I'm using WPS Wireless-N Wifi Range Router Repeater Extender in my flat where I'm using my laptop. These are antenna-less devices. Are there any life-hack tricks to increase signal/range of my repeater without buying the new more powerful repeater? I've tried already to move my repeater closer to the ceiling or putting the aluminium foil underneath, but it didn't help. Are there any methods, specific plates or materials which can boost the signal? Specification: Model: WN518W2 Frequency range: 2.4-2.4835GHz Wireless transmit power: 14 ~17 dBm (Typical) Wireless Signal Rates With Automatic Fallback: 11n: Up to 300Mbps(dynamic), 11g: Up to 54Mbps(dynamic), 11b: Up to 11Mbps(dynamic) Modulation Technology: DBPSK, DQPSK, CCK, OFDM, 16-QAM, 64-QAM Receiver Sensitivity: 300M: -68dBm@10% PER / 150M: -68dBm@10% PER / 108M: -68dBm@10% PER / 54M: -68dBm@10% PER / 11M: -85dBm@8% PER / 6M: -88dBm@10% PER / 1M: -90dBm@8% PER Product dimensions: 11 * 6 * 7cm
