  • Ubuntu second static IP, ifconfig, /etc/network/interfaces

    - by Schmoove
    I would like to add a second static IP to my local Ubuntu 11.10 desktop machine and have it automatically available after rebooting. So far I am successfully using ifconfig to to temporarily set up an alias for my primary network interface: # ifconfig eth1:0 192.168.178.3 up # ifconfig eth1 Link encap:Ethernet HWaddr c8:60:00:ef:a3:d9 inet addr:192.168.178.2 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::ca60:ff:feef:a3d9/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:61929 errors:0 dropped:0 overruns:0 frame:0 TX packets:64034 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:45330863 (45.3 MB) TX bytes:28175192 (28.1 MB) Interrupt:42 Base address:0x4000 eth1:0 Link encap:Ethernet HWaddr c8:60:00:ef:a3:d9 inet addr:192.168.178.3 Bcast:192.168.178.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:42 Base address:0x4000 However, when I add the following to /etc/network/interfaces, the alias is not up and running as expected after a reboot: # vi /etc/network/interfaces auto eth1:0 iface eth1:0 inet static address 192.168.178.3 netmask 255.255.255.0 I would like to know what to configure to get this to work. As a side note, I am running gnome shell.

  • How does Windows 7 DNS client work?

    - by Mark Allison
    I am using a local DHCP and DNS server on my home network on a linux machine. It is running CentOS 6.3 with dnsmasq 2.48. It's all working fine except for local DNS lookups for Windows machines only. I have a mix of Ubuntu, CentOS and Windows machines on the network, some virtual, some physical. I have a machine called boron and the domain is called localdomain If I ping boron from any linux machine, I get [root@lithium lists]# ping -c3 boron PING boron.localdomain (10.0.0.5) 56(84) bytes of data. 64 bytes from boron.localdomain (10.0.0.5): icmp_seq=1 ttl=64 time=0.740 ms 64 bytes from boron.localdomain (10.0.0.5): icmp_seq=2 ttl=64 time=0.478 ms 64 bytes from boron.localdomain (10.0.0.5): icmp_seq=3 ttl=64 time=0.458 ms --- boron.localdomain ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2000ms rtt min/avg/max/mdev = 0.458/0.558/0.740/0.131 ms If I do it from my Windows 7 machine, I get: Ping request could not find host boron. Please check the name and try again. If I try ping boron.localdomain I get: Pinging boron.localdomain [67.215.65.132] with 32 bytes of data: Reply from 67.215.65.132: bytes=32 time=16ms TTL=57 Reply from 67.215.65.132: bytes=32 time=188ms TTL=57 Reply from 67.215.65.132: bytes=32 time=15ms TTL=57 Reply from 67.215.65.132: bytes=32 time=14ms TTL=57 Ping statistics for 67.215.65.132: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 14ms, Maximum = 188ms, Average = 58ms which is clearly wrong. Why is it going out to the internet? Why can't my windows machine resolve the boron hostname to a FQDN? My Windows machines and linux machines get their network config from DHCP.

It would be nice to get DNS working with the DNS client on, but I might be OK without it, what do you think?

  • How to use WPA2 client mode in the Linux-based Cisco WAP4410N access point

    - by joechip
    I have a Cisco WAP4410N access point that I want to use as a client to connect to a WPA2 wireless network (for WLAN service monitoring purposes). Supposedly this access point supports a "Wireless Client/Repeater" mode that allows to do this. The Repeater function is optional (I have that box unchecked so that nobody can connect to this access point wirelessly). I have verified through SSH that the access point gets configured as a client and not as a Master. But it never associates to the SSID I ask it to. This is what iwconfig shows: ath04 IEEE 802.11ng ESSID:"myownssid" Mode:Managed Channel:0 Access Point: Not-Associated Bit Rate:0 kb/s Tx-Power:14 dBm Sensitivity=1/3 Retry:off RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=0/94 Signal level=161/162 Noise level=161/161 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 Although I've never done this from the command line, I suppose I could use wpa_supplicant or wpa_client to associate it, but I don't know how to do that without editing configuration files and the filesystem is readonly. Besides, I would have to run those commands manually after every reboot. I'd like to know how to do this the Cisco way, if possible. If not, any trick to make this work would be useful. Edit: This is with the latest firmware, 2.0.4.2. And I found that not all of the filesystem is readonly, since /var and /tmp are mounted with type ramfs.

  • KVM error with device pass through

    - by javano
    I am running the following command booting a Debian live CD passing a host PCI device to the guest as a test and KVM errors out; kvm -m 512 -boot c -net none -hda /media/AA502592502565F3/debian.iso -device pci-assign,host=07:00.0 PCI region 1 at address 0xf7920000 has size 0x80, which is not a multiple of 4K. You might experience some performance hit due to that. No IOMMU found. Unable to assign device "(null)" kvm: -device pci-assign,host=07:00.0: Device 'pci-assign' could not be initialized lspci | grep 07 07:00.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 74) I shoved an old spare NIC into my motherboard to test PCI pass through. I have searched the Internet with Goolge and found that errors relating to "No IOMMU found" often mean the PCI device is not supported by KVM. Does KVM have to support the device being "passed-through"? I though the point was to pass the device through and let the guest worry about it? Ultimately I want to pass-through a PCI random number generator, is this not going to be possible with KVM? Thank you.

  • Routing subnet over GRE tunnel

    Hi, Im trying to configure a GRE over IPSec connection between two subnets. The IPSec tunnel is opened and now I want to add a GRE tunnel over it: ip tunnel add GRE01 mode gre remote 10.244.0.1 local 10.244.245.32 ttl 255 ip link set GRE01 up ip addr add 10.244.248.126 dev GRE01 ip route add 10.244.248.125 dev GRE01 Now I have an interface GRE01 (ifconfig): GRE10 Link encap:UNSPEC HWaddr <h_addr> inet addr:10.244.248.126 P-t-P:10.244.248.126 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MTU:1476 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) And the following routes (ip route list): 10.244.248.125 dev GRE10 scope link <pub_subnet> dev eth0 proto kernel scope link src <pub_ip> default via <pub_gw> dev eth0 metric 100 As a last step, I need now to route my subnet over the tunnel: ip route add 10.245.1.224/28 10.244.248.125 However, I am getting the error Error: either "to" is duplicate, or "10.244.248.125" is a garbage. So, what I didn't understand is why I can't route my subnet over the tunnel, once the only route I have there says that it should route the tunnel IP over the GRE01 interface. Any hint? Thanks.

  • Debian can't connect to internet using LAN

    - by tampe125
    I have a headless Raspberry Pi using Debian Wheezy. I have a wifi dongle and if I connect my Raspberry using it, everything works fine: I can connect to the Internet, I can ping, I can update. However, if I get down my wifi and set up the lan interface, I lost my internet connection. I still can connect locally, using my laptop, but the connection doesn't exit (ie ping is not working). Some useful info: cat /etc/network/interfaces auto lo auto eth0 iface eth0 inet static address 192.168.0.105 netmask 255.255.255.0 gateway 192.168.0.1 ping www.google.com (nothing request timed out) ifconfig eth0 Link encap:Ethernet HWaddr b8:27:eb:a2:b5:20 inet addr:192.168.0.105 Bcast:192.168.0.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1130 errors:0 dropped:0 overruns:0 frame:0 TX packets:1116 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:97223 (94.9 KiB) TX bytes:146140 (142.7 KiB) ping 192.168.0.1 PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data. ^C --- 192.168.0.1 ping statistics --- 19 packets transmitted, 0 received, 100% packet loss, time 18007ms cat /etc/resolv.conf nameserver 8.8.8.8 netstat -r Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface default 192.168.0.1 0.0.0.0 UG 0 0 0 eth0 192.168.0.0 * 255.255.255.0 U 0 0 0 eth0 well, I think that's all...

  • Connect linux server to VPN server via PPTP

    - by wowpatrick
    I'm trying to connect a Linux (Ubuntu 10.04 LST) server to a VPN server via the PPTP client to an VPN server. I configured the PPTP client as said in the documentation. The connection is correctly added as an interface, but somehow the connection dose not work. ping -I ppp0 google.com dose not return anything and traceroute -i ppp0 only shows the first hop, and then displays nothing. Any ideas of what is going wrong? Incorrect routing configuration? ifconfig output for the configured interface: ppp0 Link encap:Point-to-Point Protocol inet addr:xx.x.xxx.xxx P-t-P:10.0.0.1 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1496 Metric:1 RX packets:415 errors:0 dropped:0 overruns:0 frame:0 TX packets:468 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:31428 (31.4 KB) TX bytes:32394 (32.3 KB) route output Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface xx.x.x.1 * 255.255.255.255 UH 0 0 0 ppp0 xx.xxx.xxx.xx sp.ip 255.255.255.255 UGH 0 0 0 eth1 192.168.3.0 * 255.255.255.0 U 0 0 0 eth2 192.168.2.0 * 255.255.255.0 U 0 0 0 eth1 default sp.ip 0.0.0.0 UG 100 0 0 eth1

  • Only tunnel certain applications via OpenVPN

    - by jinjin
    Hi, I've purchased a VPN solution, it works correctly when I have "redirect-gateway def1" in the configuration file (routing all traffic through the VPN). However when I remove that line from the configuration file, I am still able to ping-out of the machine (ping -I tap0), however I cannot ping the IP assigned to the machine (it's a public ip), i get the error: Destination Host Unreachable. I only want to have certain applications sending traffic through the VPN tunnel (eg: ZNC, irssi), all of which i can select which IP they use. However they can't recieve any data, making the tunnel essentially useless to me when disabling redirect-gateway. Any ideas on how to allow specific applications use the tunnel, without of forcing everything to go through it? My configuration file is as follows: dev tap remote #.#.#.# float #.#.#.# port 5129 comp-lzo ifconfig #.#.#.# 255.255.255.128 route-gateway #.#.#.# #redirect-gateway def1 secret key.txt cipher AES-128-CBC The output of ifconfig -a when the tunnel is connected: tap0 Link encap:Ethernet HWaddr 00:ff:47:d3:6d:f3 inet addr:#.#.#.# Bcast:#.#.#.# Mask:255.255.255.255 inet6 addr: <snip> Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:612 errors:0 dropped:0 overruns:0 frame:0 TX packets:35 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:25704 (25.1 KiB) TX bytes:6427 (6.2 KiB) EDIT: the Bcast:#.#.#.# (ifconfig) is different from route-gateway #.#.#.# (openvpn) if that makes any difference.

I would like to implement a server - client software with the following security requirements: WCF-Services need to be secured with SSL and Certificates for both, the server and the client Client certificates need to be generated programmatically upon user registration Client-certificates are deployed via a an automatically generated installer-package Altough the client-certificates are self-signed (no authorized CA for the generation server) the end-user must not add the server-certificate to the trusted certificates in the local Certificate Store My problems: I cannot find any information regarding establishing such a two-way ssl-security for wcf, while the server-certificate is not signed by an authorized CA and instead is created programmatically with "makecert"... My question: Is it technically possible to implement this requirements? If yes - could you provide some hints how to get started? Thank you!

  • php email html link, but just showing up as html code

    - by Idealflip
    Hi everyone, I'm trying to e-mail a html table, that has links within it. But when I receive the e-mail, it just shows me the html code itself. I'm using PHP pear to send the email. I try constructing a string like so $body = "<table>"; $body = $body . "<tr><td><a href='http://google.ca'>Google</a></td></tr>"; $body = $body . "</table>"; then e-mailing it, but when I receive the e-mail, it comes like this <table><tr><td><a href='http://google.ca'>Google</a></td></tr></table> Any suggestions? Thanks!

  • Apple documentation incorrect about MKMapView -regionThatFits: ?

    - by jtrim
    In the Apple documentation for the -regionThatFits: method of the MKMapView, it says that this will return a new region centered on the same point as the region that's passed in, only with the regions bounds corrected for the iPhone screen aspect ratio. This seems to be incorrect in implementation...before the call to this method, my region shows up as: $5 = { center = { latitude = 37.322898864746094, longitude = -122.03209686279297 }, span = { latitudeDelta = 14.278411865234375, longitudeDelta = 1.5202401876449585 } } ..however, after the call to this method, I end up with: $6 = { center = { latitude = 36.973427342552824, longitude = -122.03209686279297 }, span = { latitudeDelta = 14.521333317196799, longitudeDelta = 14.0625 } } This is quite a big difference on the map - this translates to the distance between Cupertino, CA and Santa Cruz, CA. Anyone else experience this discrepancy?

  • HttpWebRequest Cookie weirdness

    - by Lachman
    I'm sure I must be doing something wrong. But can't for the life of me figure out what is going on. I have a problem where it seems that the HttpWebRequest class in the framework is not correctly parsing the cookies from a web response. I'm using Fiddler to see what is going on and after making a request, the headers of the response look as such: HTTP/1.1 200 Ok Connection: close Date: Wed, 14 Jan 2009 18:20:31 GMT Server: Microsoft-IIS/6.0 P3P: policyref="/w3c/p3p.xml", CP="CAO DSP IND COR ADM CONo CUR CUSi DEV PSA PSD DELi OUR COM NAV PHY ONL PUR UNI" Set-Cookie: user=v.5,0,EX01E508801E$97$2E401000t$1BV6$A1$EC$104$A1$EC$104$A1$EC$104$21O001000$1E31!90$7CP$AE$3F$F3$D8$19o$BC$1Cd$23; Domain=.thedomain.com; path=/ Set-Cookie: minfo=v.4,EX019ECD28D6k$A3$CA$0C$CE$A2$D6$AD$D4!2$8A$EF$E8n$91$96$E1$D7$C8$0F$98$AA$ED$DC$40V$AB$9C$C1$9CF$C9$C1zIF$3A$93$C6$A7$DF$A1$7E$A7$A1$A8$BD$A6$94c$D5$E8$2F$F4$AF$A2$DF$80$89$BA$BBd$F6$2C$B6$A8; expires=Sunday, 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Set-Cookie: accttype=v.2,3,1,EX017E651B09k$A3$CA$0C$DB$A2$CB$AD$D9$8A$8C$EF$E8t$91$90$E1$DC$C89$98$AA$E0$DC$40O$A8$A4$C1$9C; expires=Sunday, 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Set-Cookie: tpid=v.1,20001; expires=Sunday, 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Set-Cookie: MC1=GUID=541977e04a341a2a4f4cdaaf49615487; expires=Sunday, 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Set-Cookie: linfo=v.4,EQC|0|0|255|1|0||||||||0|0|0||0|0|0|-1|-1; expires=Sunday, 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Set-Cookie: group=v.1,0; expires=Sunday, 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Content-Type: text/html But when I look at the response.Cookies, I see far more cookies that I am expecting, with values of different cookies being split up into different cookies. Manually getting the headers seems to result in more wierdness eg: the code foreach(string cookie in response.Headers.GetValues("Set-Cookie")) { Console.WriteLine("Cookie found: " + cookie); } produces the output: Cookie found: user=v.5 Cookie found: 0 Cookie found: EX01E508801E$97$2E401000t$1BV6$A1$EC$104$A1$EC$104$A1$EC$104$21O00 1000$1E31!90$7CP$AE$3F$F3$D8$19o$BC$1Cd$23; Domain=.thedomain.com; path=/ Cookie found: minfo=v.4 Cookie found: EX019ECD28D6k$A3$CA$0C$CE$A2$D6$AD$D4!2$8A$EF$E8n$91$96$E1$D7$C8$0 F$98$AA$ED$DC$40V$AB$9C$C1$9CF$C9$C1zIF$3A$93$C6$A7$DF$A1$7E$A7$A1$A8$BD$A6$94c$ D5$E8$2F$F4$AF$A2$DF$80$89$BA$BBd$F6$2C$B6$A8; expires=Sunday Cookie found: 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Cookie found: accttype=v.2 Cookie found: 3 Cookie found: 1 Cookie found: EX017E651B09k$A3$CA$0C$DB$A2$CB$AD$D9$8A$8C$EF$E8t$91$90$E1$DC$C89 $98$AA$E0$DC$40O$A8$A4$C1$9C; expires=Sunday Cookie found: 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Cookie found: tpid=v.1 Cookie found: 20001; expires=Sunday Cookie found: 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Cookie found: MC1=GUID=541977e04a341a2a4f4cdaaf49615487; expires=Sunday Cookie found: 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Cookie found: linfo=v.4 Cookie found: EQC|0|0|255|1|0||||||||0|0|0||0|0|0|-1|-1; expires=Sunday Cookie found: 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ Cookie found: group=v.1 Cookie found: 0; expires=Sunday Cookie found: 31-Dec-2014 23:59:59 GMT; Domain=.thedomain.com; path=/ as you can see - the first cookie in the list raw response: Set-Cookie: user=v.5,0,EX01E508801 is getting split into: Cookie found: user=v.5 Cookie found: 0 Cookie found: EX01E508801E$.......... So - what's going on here? Am I wrong? Is the HttpWebRequest class incorrectly parsing the http headers? Is the webserver that it spitting out the requests producing invalid http headers?

  • How to make parameters optional when using Rails named routes?

    - by Jason
    I have a named route: map.find '/find/:category/:state/:search_term/:permalink', :search_term=>nil, :controller=>'find', :action=>'show_match' and the following URL matches it & works OK: http://localhost:3000/find/cars/ca/TestSeachTerm/bumpedupphoto-test but if I take out the 2nd last parameter i.e. "TestSearchTerm", then the route fails to get matched, even though I have :search_term=nil in the route. http://localhost:3000/find/cars/ca//bumpedupphoto-test Can anyone see what I am doing wrong? Being trying to solve this for a few days now. Thanks!

  • What is the best way to join/merge two tables by column cell matching in Excel?

    - by blunders
    I've found this excel add-in to buy that appears to do what I need, but I'd rather have code that's open to use as I wish. While a GUI is nice, it's not required. In an attempt to make the question more clear, I'm adding some two sample "input" tables in tab delimited form, and the resulting output table: SAMPLE_INPUT_TABLE_01 NAME<tab>Location John<tab>US Mike<tab>CN Tom<tab>CA Sue<tab>RU SAMPLE_INPUT_TABLE_02 NAME<tab>Age John<tab>18 Mike<tab>36 Tom<tab>54 Mary<tab>18 SAMPLE_OUTPUT_TABLE_02 NAME<tab>Age<Location> John<tab>18<tab>US Mike<tab>36<tab>CN Tom<tab>54<tab>CA Sue<tab>""<tab>RU Mary<tab>18<tab>"" If it matters, I'm using Office 2010 on Windows 7.
