• Setting up Edimax EW-7206APg as Universal Repeater

  - by Ondra Žižka

  Hi, I've troubles setting up Edimax EW-7206APg as a Universal Repeater. I've read few manuals, but they are unclear on certain points. I've managed the repeater to get to a state when it's in a "connected" state. I've set the same WPA passphrase as the router has because I haven't seen any other place to set it at. These are my settings: System Uptime 0day:1h:33m:11s Hardware Version Rev. A Runtime Code Version 1.32 Wireless Configuration Mode Universal Repeater ESSID edimax Channel Number 6 Security WPA-shared key BSSID 00:c0:9f:40:bd:38 Associated Clients 0 Wireless Repeater Interface Configuration ESSID Dusan Security WPA BSSID 00:4f:62:23:8f:7e State Connected LAN Configuration IP Address 192.168.0.10 Subnet Mask 255.255.255.0 Default Gateway 192.168.0.1 MAC Address 00:c0:9f:40:bd:37 This is ipconfig /all: Prípona DNS podle pripojení . . . : riomail.cz Popis . . . . . . . . . . . . . . : Intel(R) PRO/Wireless 2200BG Network Connection Fyzická Adresa. . . . . . . . . . : 00-0E-35-3D-77-68 Protokol DHCP povolen . . . . . . : Ano Automatická konfigurace povolena : Ano Adresa IP . . . . . . . . . . . . : 192.168.0.5 Maska podsíte . . . . . . . . . . : 255.255.255.0 Výchozí brána . . . . . . . . . . : 192.168.0.1 Server DHCP . . . . . . . . . . . : 192.168.0.1 Servery DNS . . . . . . . . . . . : 94.74.192.252 94.74.192.244 I can ping the repeater, I can ping the root AP, but not a DNS server or any other IP beyond the root AP. Anyone has an idea what's wrong? Thanks, Ondra

• Issue in setting up VPN connection (IKEv1) using android (ICS vpn client) with Strongswan 4.5.0 server

  - by Kushagra Bhatnagar

  I am facing issues in setting up VPN connection(IKEv1) using android (ICS vpn client) and Strongswan 4.5.0 server. Below is the set up: Strongswan server is running on ubuntu linux machine which is connected to some wifi hotspot. Using the steps in this guide link, I generated CA, server and client certificate. Once certificates are generated, following (clientCert.p12 and caCert.pem) are sent to mobile via mail and installed on android device. Below are the ip addresses assigned to various interfaces Linux server wlan0 interface ip where server is running: 192.168.43.212, android device eth0 interface ip address: 192.168.43.62; Android device is also attached with the same wifi hotspot. On the Android device, I uses IPsec Xauth RSA option for setting up VPN authentication configuration. I am using the following ipsec.conf configuration: # basic configuration config setup plutodebug=all # crlcheckinterval=600 # strictcrlpolicy=yes # cachecrls=yes nat_traversal=yes # charonstart=yes plutostart=yes # Add connections here. # Sample VPN connections conn ios1 keyexchange=ikev1 authby=xauthrsasig xauth=server left=%defaultroute leftsubnet=0.0.0.0/0 leftfirewall=yes leftcert=serverCert.pem right=192.168.43.62 rightsubnet=10.0.0.0/24 rightsourceip=10.0.0.2 rightcert=clientCert.pem pfs=no auto=add      With the above configurations when I enable VPN on android device, VPN connection is not successful and it gets timed out in Authentication phase. I ran wireshark on both the android device and strongswan server, from the tcpdump below are the observations. Initially Identity Protection (Main mode) exchanges happens between device and server and all are successful. After all successful Identity Protection (Main mode) exchanges server is sending Transaction (Config mode) to device. In reply android device is sending Informational message instead of Transaction (Config mode) message. Further server is keep on sending Transaction (Config mode) message and device is again sending Identity Protection (Main mode) messages. Finally timeout happens and connection fails. I also capture Strongswan server logs and below are the snippets from the server logs which also verifies the same(described above).

• ASA 5505 stops local internet when connected to VPN

  - by g18c

  Hi I have a Cisco ASA router running firmware 8.2(5) which hosts an internal LAN on 192.168.30.0/24. I have used the VPN Wizard to setup L2TP access and I can connect in fine from a Windows box and can ping hosts behind the VPN router. However, when connected to the VPN I can no longer ping out to my internet or browse web pages. I would like to be able to access the VPN, and also browse the internet at the same time - I understand this is called split tunneling (have ticked the setting in the wizard but to no effect) and if so how do I do this? Alternatively, if split tunneling is a pain to setup, then making the connected VPN client have internet access from the ASA WAN IP would be OK. Thanks, Chris names ! interface Ethernet0/0 switchport access vlan 2 ! interface Ethernet0/1 ! interface Vlan1 nameif inside security-level 100 ip address 192.168.30.1 255.255.255.0 ! interface Vlan2 nameif outside security-level 0 ip address 208.74.158.58 255.255.255.252 ! ftp mode passive access-list inside_nat0_outbound extended permit ip any 10.10.10.0 255.255.255.128 access-list inside_nat0_outbound extended permit ip 192.168.30.0 255.255.255.0 192.168.30.192 255.255.255.192 access-list DefaultRAGroup_splitTunnelAcl standard permit 192.168.30.0 255.255.255.0 access-list DefaultRAGroup_splitTunnelAcl_1 standard permit 192.168.30.0 255.255.255.0 pager lines 24 logging asdm informational mtu inside 1500 mtu outside 1500 ip local pool LANVPNPOOL 192.168.30.220-192.168.30.249 mask 255.255.255.0 icmp unreachable rate-limit 1 burst-size 1 no asdm history enable arp timeout 14400 global (outside) 1 interface nat (inside) 0 access-list inside_nat0_outbound nat (inside) 1 192.168.30.0 255.255.255.0 route outside 0.0.0.0 0.0.0.0 208.74.158.57 1 timeout xlate 3:00:00 timeout conn 1:00:00 half-closed 0:10:00 udp 0:02:00 icmp 0:00:02 timeout sunrpc 0:10:00 h323 0:05:00 h225 1:00:00 mgcp 0:05:00 mgcp-pat 0:05:00 timeout sip 0:30:00 sip_media 0:02:00 sip-invite 0:03:00 sip-disconnect 0:02:00 timeout sip-provisional-media 0:02:00 uauth 0:05:00 absolute timeout tcp-proxy-reassembly 0:01:00 timeout floating-conn 0:00:00 dynamic-access-policy-record DfltAccessPolicy http server enable http 192.168.30.0 255.255.255.0 inside snmp-server enable traps snmp authentication linkup linkdown coldstart crypto ipsec transform-set ESP-AES-256-MD5 esp-aes-256 esp-md5-hmac crypto ipsec transform-set ESP-DES-SHA esp-des esp-sha-hmac crypto ipsec transform-set ESP-3DES-SHA esp-3des esp-sha-hmac crypto ipsec transform-set ESP-DES-MD5 esp-des esp-md5-hmac crypto ipsec transform-set ESP-AES-192-MD5 esp-aes-192 esp-md5-hmac crypto ipsec transform-set ESP-3DES-MD5 esp-3des esp-md5-hmac crypto ipsec transform-set ESP-AES-256-SHA esp-aes-256 esp-sha-hmac crypto ipsec transform-set ESP-AES-128-SHA esp-aes esp-sha-hmac crypto ipsec transform-set ESP-AES-192-SHA esp-aes-192 esp-sha-hmac crypto ipsec transform-set ESP-AES-128-MD5 esp-aes esp-md5-hmac crypto ipsec transform-set TRANS_ESP_3DES_SHA esp-3des esp-sha-hmac crypto ipsec transform-set TRANS_ESP_3DES_SHA mode transport crypto ipsec security-association lifetime seconds 28800 crypto ipsec security-association lifetime kilobytes 4608000 crypto dynamic-map SYSTEM_DEFAULT_CRYPTO_MAP 65535 set transform-set ESP-AES-128-SHA ESP-AES-128-MD5 ESP-AES-192-SHA ESP-AES-192-MD5 ESP-AES-256-SHA ESP-AES-256-MD5 ESP-3DES-SHA ESP-3DES-MD5 ESP-DES-SHA ESP-DES-MD5 TRANS_ESP_3DES_SHA crypto map outside_map 65535 ipsec-isakmp dynamic SYSTEM_DEFAULT_CRYPTO_MAP crypto map outside_map interface outside crypto isakmp enable outside crypto isakmp policy 10 authentication pre-share encryption 3des hash sha group 2 lifetime 86400 telnet timeout 5 ssh timeout 5 console timeout 0 dhcpd auto_config outside ! threat-detection basic-threat threat-detection statistics access-list no threat-detection statistics tcp-intercept webvpn group-policy DefaultRAGroup internal group-policy DefaultRAGroup attributes dns-server value 192.168.30.3 vpn-tunnel-protocol l2tp-ipsec split-tunnel-policy tunnelspecified split-tunnel-network-list value DefaultRAGroup_splitTunnelAcl_1 username user password Cj7W5X7wERleAewO8ENYtg== nt-encrypted privilege 0 tunnel-group DefaultRAGroup general-attributes address-pool LANVPNPOOL default-group-policy DefaultRAGroup tunnel-group DefaultRAGroup ipsec-attributes pre-shared-key ***** tunnel-group DefaultRAGroup ppp-attributes no authentication chap authentication ms-chap-v2 ! class-map inspection_default match default-inspection-traffic ! ! policy-map type inspect dns preset_dns_map parameters message-length maximum client auto message-length maximum 512 policy-map global_policy class inspection_default inspect dns preset_dns_map inspect ftp inspect h323 h225 inspect h323 ras inspect rsh inspect rtsp inspect esmtp inspect sqlnet inspect skinny inspect sunrpc inspect xdmcp inspect sip inspect netbios inspect tftp inspect ip-options ! service-policy global_policy global prompt hostname context : end

• Cisco 678 Will Not Work using PPPoE - Possibly Because I Configured it Incorrectly..?

  - by Brian Stinar

  I am attempting to configure a Cisco 678 because I am totally sick on my Actiontec. However, I am running into some problems. It seems as though the Cisco is able to train the line, but I am unable to ping out. I am all right at programming, but still learning a lot when it comes to being a system administrator. I apologize in advance if I did something ridiculous, or am attempting to configure this device to do something it was not designed to do. It is almost like I am not correctly configuring the device to grab it's IP using PPPoA (like my Actiontec.) The output from "show running" (below) makes me think this too. Below are the commands I ran in order to configure this: # en # set nvram erase # write # reboot # en # set nat enable # set dhcp server enable # set PPP wan0-0 ipcp 0.0.0.0 # set ppp wan0-0 dns 0.0.0.0 # set PPP wan0-0 login xxxxx // My actual login # set PPP wan0-0 password yyyyy // My actual password # set PPP restart enabled # set int wan0-0 close # set int wan0-0 vpi 0 # set int wan0-0 vci 32 # set int wan0-0 open # write # reboot Here is the output from a few commands I thought could provide some useful information: cbos#ping 74.125.224.113 Sending 1 8 byte ping(s) to 74.125.224.113 every 2 second(s) Request timed out cbos#show version Cisco Broadband Operating System CBOS (tm) 678 Software (C678-I-M), Version v2.4.9 - Release Software Copyright (c) 1986-2001 by cisco Systems, Inc.

• Cannot connect to website - SSL handshaking fails

  - by ravenspoint

  So I cannot connect to certain websites. Just a few, most are OK. The one I really care about is paypal.com. I have done the usual things. Let's see: Checked my etc/hosts Flushed the DNS cache Checked firewall Switched on & off virus protection Switched on and off ad blocking pinged the sites Eventually, I decided to look at what curl is saying in detail == Info: About to connect() to www.paypal.com port 443 (#0) == Info: Trying 66.211.169.2... == Info: connected == Info: SSLv3, TLS handshake, Client hello (1): => Send SSL data, 110 bytes (0x6e) 0000: 01 00 00 6a 03 01 4f 6c aa 8c 57 2b 3d 1e 74 64 ...j..Ol..W+=.td 0010: c1 27 25 a5 3a 12 7f 3f 41 0a 17 15 2e c9 67 7c .'%.:.?A.....g| 0020: b3 e1 f6 9a db a9 00 00 2a 00 39 00 38 00 35 00 ........*.9.8.5. 0030: 16 00 13 00 0a 00 33 00 32 00 2f 00 07 00 05 00 ......3.2./..... 0040: 04 00 15 00 12 00 09 00 14 00 11 00 08 00 06 00 ................ 0050: 03 00 ff 01 00 00 17 00 00 00 13 00 11 00 00 0e ................ 0060: 77 77 77 2e 70 61 79 70 61 6c 2e 63 6f 6d www.paypal.com (hangs here for ever) This looks to me like paypal is refusing to reply to the first SSL handshake. I don't know much about SSL, but compaing to the output from a site that works for me seems to make it obvious == Info: About to connect() to www.cibc.com port 443 (#0) == Info: Trying 159.231.80.200... == Info: connected == Info: SSLv3, TLS handshake, Client hello (1): => Send SSL data, 108 bytes (0x6c) 0000: 01 00 00 68 03 01 4f 6c ad 6a 1f 67 d5 84 c4 4b ...h..Ol.j.g...K 0010: 0d 49 ae d6 b9 5b c3 63 f9 48 aa 18 da 43 d1 32 .I...[.c.H...C.2 0020: 47 ae 17 e5 cd e9 00 00 2a 00 39 00 38 00 35 00 G.......*.9.8.5. 0030: 16 00 13 00 0a 00 33 00 32 00 2f 00 07 00 05 00 ......3.2./..... 0040: 04 00 15 00 12 00 09 00 14 00 11 00 08 00 06 00 ................ 0050: 03 00 ff 01 00 00 15 00 00 00 11 00 0f 00 00 0c ................ 0060: 77 77 77 2e 63 69 62 63 2e 63 6f 6d www.cibc.com == Info: SSLv3, TLS handshake, Server hello (2): <= Recv SSL data, 74 bytes (0x4a) 0000: 02 00 00 46 03 01 00 00 58 cf 26 e2 e1 65 db 11 ...F....X.&..e.. 0010: bc 6f 26 7b 3b 6d eb 14 5f ad 47 dd 86 ea 4d a3 .o&{;m.._.G...M. 0020: fb 9f b7 2a 54 3e 20 5f 6b 04 5a 12 38 64 5d 18 ...*T> _k.Z.8d]. 0030: 65 9e e9 cd 61 eb 91 c1 16 25 61 30 bb 08 2a 78 e...a....%a0..*x 0040: b8 ee b8 7e f2 65 6a 00 04 00 ...~.ej... == Info: SSLv3, TLS handshake, CERT (11): ... and so on - working nicely eventually get some nice HTML Now I am reaaly stuck. This has been going on for five days, so I am pretty sure that the problem is not with paypal. But what on my system could be interfering with the SSL handshaking done by curl with this particular site? I suppose I could not be offering any certificates that PayPal accepts, but wouldn't I get a reply telling me so, or at least giving an error?

  I have a server and the postfix client on it. Since several days, I noticed a lot of processes running there. When checked, there are a lot of emails sent. Here is an example from the mail log: Aug 18 11:54:56 mem postfix/smtpd[9963]: connect from dslb-188-096-082-167.188.096.pools.vodafone-ip.de[188.96.82.167] Aug 18 11:54:56 mem postfix/smtpd[9301]: connect from unknown[186.113.45.4] Aug 18 11:54:56 mem postfix/smtpd[9963]: 525E7114012D: client=dslb-188-096-082-167.188.096.pools.vodafone-ip.de[188.96.82.167] Aug 18 11:54:56 mem postfix/cleanup[9970]: 525E7114012D: message-id=<B55835C9027BFA9D16CCBB556DB2F48BB82DF004000480BA-db0c3ce8aa74446411898d0d2feb3001@email.filmforthoughtinc.com> Aug 18 11:54:56 mem postfix/qmgr[2581]: 525E7114012D: from=<[email protected]>, size=10702, nrcpt=1 (queue active) Aug 18 11:54:56 mem postfix/smtpd[9301]: EC52711401DC: client=unknown[186.113.45.4] Aug 18 11:54:57 mem postfix/smtpd[9963]: disconnect from dslb-188-096-082-167.188.096.pools.vodafone-ip.de[188.96.82.167] Aug 18 11:54:57 mem postfix/cleanup[8597]: EC52711401DC: message-id=<4C905D97606B436FE50C6F738DE014D9D84F2185BA815D81-1a4dbe6fc2bfcc8183f5faf901cfa15e@email.manguerasespecializadas.com> Aug 18 11:54:57 mem postfix/smtp[9971]: 525E7114012D: to=<[email protected]>, relay=mail.mdpi.com[209.237.236.228]:25, delay=1.2, delays=0.55/0/0.45/0.16, dsn=5.1.1, status=bounced (host mail.mdpi.com[209.237.236.228] said: 550 5.1.1 <[email protected]>: Recipient address rejected: mdpi.com (in reply to RCPT TO command)) Aug 18 11:54:57 mem postfix/cleanup[10067]: 8B1E11140268: message-id=<[email protected]> Aug 18 11:54:57 mem postfix/bounce[10001]: 525E7114012D: sender non-delivery notification: 8B1E11140268 Aug 18 11:54:57 mem postfix/qmgr[2581]: 8B1E11140268: from=<>, size=12693, nrcpt=1 (queue active) Aug 18 11:54:57 mem postfix/qmgr[2581]: 525E7114012D: removed Aug 18 11:54:57 mem postfix/qmgr[2581]: EC52711401DC: from=<[email protected]>, size=10978, nrcpt=1 (queue active) Aug 18 11:54:57 mem postfix/smtp[10013]: connect to aspmx.l.google.com[2607:f8b0:400d:c03::1b]:25: Network is unreachable Aug 18 11:54:57 mem postfix/smtpd[9301]: disconnect from unknown[186.113.45.4] Aug 18 11:54:58 mem postfix/smtp[10013]: 8B1E11140268: to=<[email protected]>, relay=aspmx.l.google.com[74.125.22.26]:25, delay=0.5, delays=0.06/0/0.28/0.16, dsn=5.1.1, status=bounced (host aspmx.l.google.com[74.125.22.26] said: 550-5.1.1 The email account that you tried to reach does not exist.

• Solaris 10 branded zone VM Templates for Solaris 11 on OTN

  - by jsavit

  Early this year I wrote the article Ours Goes To 11 which describes the ability to import Solaris 10 systems into a "Solaris 10 branded zone" under Oracle Solaris 11. I did this using Solaris 11 Express, and the capability remains in Solaris 11 with only slight changes. This important tool lets you painlessly inhaling a Solaris Container from Solaris 10 or entire Solaris 10 systems ("the global zone") into virtualized environments on a Solaris 11 OS. Just recently, Oracle provided Oracle VM Templates for Oracle Solaris 10 Zones to let you create Solaris 10 branded zones for Solaris 11 even if you don't currently have access to install media or a running Solaris 10 system. To use this, just download the Oracle VM Template for Oracle Solaris Zone 10 from OTN at http://www.oracle.com/technetwork/server-storage/solaris11/downloads/virtual-machines-1355605.html. This page contains images of Oracle Solaris 10 8/11 (the recent update to Solaris 10) in SPARC and x86 formats suitable for creating branded zones. The same page also has a VirtualBox image you can download for a complete Solaris 10 install in a guest virtual machine you can run on any host OS that supports VirtualBox. Both sets of downloads provide a quick - and extremely easy - way to set up a virtual Solaris 10 environment. In the case of the Oracle VM Templates, they illustrate several advanced features of Solaris 11. To start, just go to the above link, download the template for the hardware platform (SPARC or x86) you want, and download the README file also linked from that page. Install prerequisites The README file tells you to install the prerequisite Solaris 11 package that implements the Solaris 10 brand. Then you can install instances of zones with that brand. # pkg install pkg:/system/zones/brand/brand-solaris10 Packages to install: 1 Create boot environment: No Create backup boot environment: Yes DOWNLOAD PKGS FILES XFER (MB) Completed 1/1 44/44 0.4/0.4 PHASE ACTIONS Install Phase 74/74 PHASE ITEMS Package State Update Phase 1/1 Image State Update Phase 2/2 That took only a few minutes, and didn't require a reboot. Install the Solaris 10 zone Now it's time to run the downloaded template file. First make it executable via the chmod command, of course. I found that (unlike stated in the README) there was no need to rename the downloaded file to remove the .bin. When you run it you provide several parameters to describe the zone configuration: -a IP address - the IP address and optional netmask for the zone. This is the only mandatory parameter. -z zonename - the name of the zone you would like to create. -i interface - the package will create an exclusive-IP zone using a virtual NIC (vnic) based on this physical interface. In my case, I have a NIC called rge0. -p PATH - specifies the path in which you want the zoneroot to be placed. In my case, I have a ZFS dataset mounted at /zones, and this will create a zoneroot at /zones/s10u10. Kicking it off, you will see a copyright message, and then messages showing progress building the zone, which only takes a few minutes. # ./solaris-10u10-x86.bin -p /zones -a 192.168.1.100 -i rge0 -z s10u10 ... ...

Zone s10u10 booted The zone's root password has been set using the root password of the local host. You can change the zone's root password to further harden the security of the zone: being root, log into the zone from the local host with the command 'zlogin s10u10'. Once logged in, change the root password with the command 'passwd'. The nifty part in my opinion (besides being so easy), is that the zone was created as an exclusive-IP zone on a virtual NIC. This network configuration lets you enforce traffic isolation from other zones, enforce network Quality of Service, and even let the zone set its own characteristics like IP address and packet size. Independence of the zone's network characteristics from the global zone is one of the enhancements in Solaris 10 that make it easier to consolidate zones while preserving their autonomy, yet provide control in a consolidated environment. Let's see what the virtual network environment looks like by issuing commands from the Solaris 11 global zone. First I'll use Old School ifconfig, and then I'll use the new ipadm and dladm commands. # ifconfig -a4 lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1 inet 127.0.0.1 netmask ff000000 rge0: flags=1004943<UP,BROADCAST,RUNNING,PROMISC,MULTICAST,DHCP,IPv4> mtu 1500 index 2 inet 192.168.1.3 netmask ffffff00 broadcast 192.168.1.255 ether 0:14:d1:18:ac:bc vboxnet0: flags=201000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,CoS> mtu 1500 index 3 inet 192.168.56.1 netmask ffffff00 broadcast 192.168.56.255 ether 8:0:27:f8:62:1c # dladm show-phys LINK MEDIA STATE SPEED DUPLEX DEVICE yge0 Ethernet unknown 0 unknown yge0 yge1 Ethernet unknown 0 unknown yge1 rge0 Ethernet up 1000 full rge0 vboxnet0 Ethernet up 1000 full vboxnet0 # dladm show-link LINK CLASS MTU STATE OVER yge0 phys 1500 unknown -- yge1 phys 1500 unknown -- rge0 phys 1500 up -- vboxnet0 phys 1500 up -- vnicZBI13379 vnic 1500 up rge0 s10u10/vnicZBI13379 vnic 1500 up rge0 s10u10/net0 vnic 1500 up rge0 # dladm show-vnic LINK OVER SPEED MACADDRESS MACADDRTYPE VID vnicZBI13379 rge0 1000 2:8:20:5c:1a:cc random 0 s10u10/vnicZBI13379 rge0 1000 2:8:20:5c:1a:cc random 0 s10u10/net0 rge0 1000 2:8:20:9d:d0:79 random 0 # ipadm show-addr ADDROBJ TYPE STATE ADDR lo0/v4 static ok 127.0.0.1/8 rge0/_a dhcp ok 192.168.1.3/24 vboxnet0/_a static ok 192.168.56.1/24 lo0/v6 static ok ::1/128 Log into the zone The install step already booted the zone, so lets log into it. Notice how you have to be appropriately privileged to log into a zone. This is my home system so I'm being a bit cavalier, but in a production environment you can give granular control of who can login to which zones. Voila! a Solaris 10 environment under a Solaris 11 kernel.

• SSH new connection begins to hang (not reject or terminate) after a day or so on Ubuntu 13.04 server

  - by kross

  Recently we upgraded the server from 12.04 LTS server to 13.04. All was well, including after a reboot. With all packages updated we began to see a strange issue, ssh works for a day or so (unclear on timing) then a later request for SSH hangs (cannot ctrl+c, nothing).

• How to set up spf records to send mail from google hosted apps to gmail addresses

  - by Chris Adams

  Hi there, I'm trying to work out why email I send from one domain I own is rejected by another that I own, and while I think it may be related to how I've setup spf records, I'm not sure what steps I need to take to fix it. Here's the error message I receive: Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550-Verification failed for <[email protected]> 550-No Such User Here 550 Sender verify failed (state 14).

• T38modem manuals?

  - by Brian Postow

  Are there any T38modem users here? I'm trying to figure out how to call T38modem with SIP. I've got everything except the --route option for receiving. I know my own phone number, but I am not sure how to set it up. Currently, I have: --route "modem:0.*"="sip:<dn>@64.136.174.30" --route "modem:1.*=sip:[email protected]" I've also tried: --route "modem:*.*"="sip:<dn>@64.136.174.30" --route"sip:*@74.94.184.154"="modem:<dn>@127.0.0.1" what amI doing wrong? And where (other than t38modem --help) can I find some documentation on how to use it? thanks.

• installed openstack using devstack install shell script but getting 500 error when i try opening dashboard

  - by Arvind

  I followed the instructions at http://devstack.org/guides/single-machine.html to install OpenStack. I first installed Ubuntu on my Windows 7 PC using the officially supported Windows installer for Ubuntu 12.04 LTS. And after that I followed the instructions at above page to install OpenStack. As per instructions, I should be able to access the dashboard aka Horizon, at http://192.168.1.4/ (thats the IP of the PC on which I installed Ubuntu-OpenStack). However I am getting a 500 error web page when I open that. How do I resolve this error? I want to set up a dev environment for OpenStack.

• Running a simple integration scenario using the Oracle Big Data Connectors on Hadoop/HDFS cluster

  - by hamsun

  Between the elephant ( the tradional image of the Hadoop framework) and the Oracle Iron Man (Big Data..) an english setter could be seen as the link to the right data Data, Data, Data, we are living in a world where data technology based on popular applications , search engines, Webservers, rich sms messages, email clients, weather forecasts and so on, have a predominant role in our life. More and more technologies are used to analyze/track our behavior, try to detect patterns, to propose us "the best/right user experience" from the Google Ad services, to Telco companies or large consumer sites (like Amazon:) ). The more we use all these technologies, the more we generate data, and thus there is a need of huge data marts and specific hardware/software servers (as the Exadata servers) in order to treat/analyze/understand the trends and offer new services to the users. Some of these "data feeds" are raw, unstructured data, and cannot be processed effectively by normal SQL queries. Large scale distributed processing was an emerging infrastructure need and the solution seemed to be the "collocation of compute nodes with the data", which in turn leaded to MapReduce parallel patterns and the development of the Hadoop framework, which is based on MapReduce and a distributed file system (HDFS) that runs on larger clusters of rather inexpensive servers. Several Oracle products are using the distributed / aggregation pattern for data calculation ( Coherence, NoSql, times ten ) so once that you are familiar with one of these technologies, lets says with coherence aggregators, you will find the whole Hadoop, MapReduce concept very similar. Oracle Big Data Appliance is based on the Cloudera Distribution (CDH), and the Oracle Big Data Connectors can be plugged on a Hadoop cluster running the CDH distribution or equivalent Hadoop clusters. In this paper, a "lab like" implementation of this concept is done on a single Linux X64 server, running an Oracle Database 11g Enterprise Edition Release 11.2.0.4.0, and a single node Apache hadoop-1.2.1 HDFS cluster, using the SQL connector for HDFS. The whole setup is fairly simple: Install on a Linux x64 server ( or virtual box appliance) an Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 server Get the Apache Hadoop distribution from: http://mir2.ovh.net/ftp.apache.org/dist/hadoop/common/hadoop-1.2.1. Get the Oracle Big Data Connectors from: http://www.oracle.com/technetwork/bdc/big-data-connectors/downloads/index.html?ssSourceSiteId=ocomen. Check the java version of your Linux server with the command: java -version java version "1.7.0_40" Java(TM) SE Runtime Environment (build 1.7.0_40-b43) Java HotSpot(TM) 64-Bit Server VM (build 24.0-b56, mixed mode) Decompress the hadoop hadoop-1.2.1.tar.gz file to /u01/hadoop-1.2.1 Modify your .bash_profile export HADOOP_HOME=/u01/hadoop-1.2.1 export PATH=$PATH:$HADOOP_HOME/bin export HIVE_HOME=/u01/hive-0.11.0 export PATH=$PATH:$HADOOP_HOME/bin:$HIVE_HOME/bin (also see my sample .bash_profile) Set up ssh trust for Hadoop process, this is a mandatory step, in our case we have to establish a "local trust" as will are using a single node configuration copy the new public keys to the list of authorized keys connect and test the ssh setup to your localhost: We will run a "pseudo-Hadoop cluster", in what is called "local standalone mode", all the Hadoop java components are running in one Java process, this is enough for our demo purposes. We need to "fine tune" some Hadoop configuration files, we have to go at our $HADOOP_HOME/conf, and modify the files: core-site.xml hdfs-site.xml mapred-site.xml check that the hadoop binaries are referenced correctly from the command line by executing: hadoop -version As Hadoop is managing our "clustered HDFS" file system we have to create "the mount point" and format it , the mount point will be declared to core-site.xml as: The layout under the /u01/hadoop-1.2.1/data will be created and used by other hadoop components (MapReduce = /mapred/...) HDFS is using the /dfs/... layout structure format the HDFS hadoop file system: Start the java components for the HDFS system As an additional check, you can use the GUI Hadoop browsers to check the content of your HDFS configurations: Once our HDFS Hadoop setup is done you can use the HDFS file system to store data ( big data : )), and plug them back and forth to Oracle Databases by the means of the Big Data Connectors ( which is the next configuration step). You can create / use a Hive db, but in our case we will make a simple integration of "raw data" , through the creation of an External Table to a local Oracle instance ( on the same Linux box, we run the Hadoop HDFS one node cluster and one Oracle DB). Download some public "big data", I use the site: http://france.meteofrance.com/france/observations, from where I can get *.csv files for my big data simulations :). Here is the data layout of my example file: Download the Big Data Connector from the OTN (oraosch-2.2.0.zip), unzip it to your local file system (see picture below) Modify your environment in order to access the connector libraries , and make the following test: [oracle@dg1 bin]$./hdfs_stream Usage: hdfs_stream locationFile [oracle@dg1 bin]$ Load the data to the Hadoop hdfs file system: hadoop fs -mkdir bgtest_data hadoop fs -put obsFrance.txt bgtest_data/obsFrance.txt hadoop fs -ls /user/oracle/bgtest_data/obsFrance.txt [oracle@dg1 bg-data-raw]$ hadoop fs -ls /user/oracle/bgtest_data/obsFrance.txt Found 1 items -rw-r--r-- 1 oracle supergroup 54103 2013-10-22 06:10 /user/oracle/bgtest_data/obsFrance.txt [oracle@dg1 bg-data-raw]$hadoop fs -ls hdfs:///user/oracle/bgtest_data/obsFrance.txt Found 1 items -rw-r--r-- 1 oracle supergroup 54103 2013-10-22 06:10 /user/oracle/bgtest_data/obsFrance.txt Check the content of the HDFS with the browser UI: Start the Oracle database, and run the following script in order to create the Oracle database user, the Oracle directories for the Oracle Big Data Connector (dg1 it’s my own db id replace accordingly yours): #!/bin/bash export ORAENV_ASK=NO export ORACLE_SID=dg1 . oraenv sqlplus /nolog <<EOF CONNECT / AS sysdba; CREATE OR REPLACE DIRECTORY osch_bin_path AS '/u01/orahdfs-2.2.0/bin'; CREATE USER BGUSER IDENTIFIED BY oracle; GRANT CREATE SESSION, CREATE TABLE TO BGUSER; GRANT EXECUTE ON sys.utl_file TO BGUSER; GRANT READ, EXECUTE ON DIRECTORY osch_bin_path TO BGUSER; CREATE OR REPLACE DIRECTORY BGT_LOG_DIR as '/u01/BG_TEST/logs'; GRANT READ, WRITE ON DIRECTORY BGT_LOG_DIR to BGUSER; CREATE OR REPLACE DIRECTORY BGT_DATA_DIR as '/u01/BG_TEST/data'; GRANT READ, WRITE ON DIRECTORY BGT_DATA_DIR to BGUSER; EOF Put the following in a file named t3.sh and make it executable, hadoop jar $OSCH_HOME/jlib/orahdfs.jar \ oracle.hadoop.exttab.ExternalTable \ -D oracle.hadoop.exttab.tableName=BGTEST_DP_XTAB \ -D oracle.hadoop.exttab.defaultDirectory=BGT_DATA_DIR \ -D oracle.hadoop.exttab.dataPaths="hdfs:///user/oracle/bgtest_data/obsFrance.txt" \ -D oracle.hadoop.exttab.columnCount=7 \ -D oracle.hadoop.connection.url=jdbc:oracle:thin:@//localhost:1521/dg1 \ -D oracle.hadoop.connection.user=BGUSER \ -D oracle.hadoop.exttab.printStackTrace=true \ -createTable --noexecute then test the creation fo the external table with it: [oracle@dg1 samples]$ ./t3.sh ./t3.sh: line 2: /u01/orahdfs-2.2.0: Is a directory Oracle SQL Connector for HDFS Release 2.2.0 - Production Copyright (c) 2011, 2013, Oracle and/or its affiliates.

• My IIS server won't serve SSL sites to some browsers

  - by sbleon

  (Update: This is now cross-posted at http://stackoverflow.com/questions/3355000. This is the more appropriate forum, but StackOverflow gets a lot more traffic.) I've got an IIS 6.0 server that won't serve pages over SSL to some browsers. In Webkit-based browsers on OS X 10.6, I can't load pages at all. In MSIE 8 on Windows XP SP3, I can load pages, but it will sometimes hang downloading images or sending POSTs. Working: Firefox 3.6 (OS X + Windows) Chrome (Windows) Partially Working: MSIE 8 (works sometimes, but hangs up, especially on POSTs) Not Working: Chrome 5 (OS X) Safari 5 (OS X) Mobile Safari (iOS 4) On OS X (the easiest platform for me to test on), Chrome and Firefox both negotiate the same TLS Cipher, but Chrome hangs on or after the post-negotiation handshake.

• How do I obtain a valid DNS resolution given just an IP address?

  - by Dee Newcum

  Is there a publicly-available DNS server somewhere that will respond to requests like: 74_125_225_50.anyip.com And will return 74.125.225.50 for the above request? That is, every single possible IP address can queried by name instead of number. http://ipq.co/ is close to what I'm looking for, but it requires you to first register an IP address before you can query its DNS name. I want a service that does a straightforward mapping from domain name to IP address. Why do I want to do this? I have a program that we use at work that requires a DNS lookup, but I need to be able to give it bare IP addresses. (long story... it's a server that I don't control, so I can't work around it using /etc/hosts)

• scalability with nginx, passenger, ruby on rails setup

  - by Dani Cela

  Hey guys I had a question regarding scalability for my RoR application. We have been optimizing our application over the last few days and after running blitz.io, notice that our application times out after maybe 1000 hits in 30 seconds we experienced massive timeouts. In the 1 minute test apparently 74% of users would have timed out. Look at the performance of my website: http://blitz.io/report/1c8eb2f395a5eadeabd62fd831ada9e5 Not saying that our website will in any way experience this now, but I wish to design the infrastructure to handle this. What is normally done in this situation? Currently we have one web server and one database server. Would load balancing be the route to go?

• Use a Free Tool to Edit, Delete, or Restore the Default Hosts File in Windows

  - by Lori Kaufman

  The hosts file in Windows contains mappings of IP addresses to host names, like an address book for your computer. Your PC uses IP addresses to find websites, so it needs to translate the host names into IP addresses to access websites. When you enter a host name in a browser to visit a website, that host name is looked up in DNS servers to find the IP address. If you enter IP addresses and host names for websites you visit often, these websites will load faster, because the hosts file is loaded into memory when Windows start and overrides DNS server queries, creating a shortcut to the sites. Because the hosts file is checked first, you can also use it to block websites from tracking your activities on the internet, as well as block ads, banners, third-party cookies, and other intrusive elements on webpages. Your computer has its own host address, known as its “localhost” address. The IP address for localhost is 127.0.0.1. To block sites and website elements, you can enter the host name for the unwanted site in the hosts file and associate it with the localhost address. Blocking ads and other undesirable webpage elements, can also speed up the loading of websites. You don’t have to wait for all those items to load. The default hosts file that comes with Windows does not contain any host name/IP address mappings. You can add mappings manually, such as the IP address 74.125.224.72 for www.google.com. As an example of blocking an ad server website, you can enter the following line in your hosts file to block doubleclick.net from serving you ads.

• How do I send traffic from my Mac's wifi to my VPN client?

  - by Heath Borders

  I need to connect my Android to a Juniper VPN. Unfortunately, Juniper doesn't support Android on our VPN version. We've already put in a feature request for it, but we have no idea how long it will take to be complete. Right now, I connect to the Juniper VPN with a Juniper Mac OSX VPN client that uses Java to install kernel extensions to start and stop the VPN. Thus, I can't use the Network panel in System Preferences to create a VPN device, which means it won't show up in the 'Sharing' panel's Internet Sharing Share your connection from: menu, as suggested here. I used newproc.d to see what /usr/libexec/InternetSharing did when it ran, and it runs the following processes: 2013 Nov 1 00:26:54 5565 <1> 64b /usr/libexec/launchdadd 2013 Nov 1 00:26:55 5566 <1> 64b /usr/libexec/InternetSharing 2013 Nov 1 00:26:56 5568 <5566> 64b natpmpd -d -y bridge100 en0 2013 Nov 1 00:26:56 5569 <1> 64b /usr/libexec/pfd -d 2013 Nov 1 00:26:56 5567 <5566> 64b bootpd -d -P My Juniper VPN client creates the following devices (output of ifconfig): jnc0: flags=841<UP,RUNNING,SIMPLEX> mtu 1400 inet 10.61.9.61 netmask 0xffffffff open (pid 920) jnc1: flags=841<UP,RUNNING,SIMPLEX> mtu 1450 closed So, it seems like I should just be able to do this and have everything work: sudo killall -9 natpmpd sudo /usr/libexec/natpmpd -y bridge100 jnc0 My android connected fine and could hit public internet sites, but it couldn't hit private VPN sites.

Is that possible? Because in the processors ratings these processors are about the same. Is it possible that this is because of cache or something? And if so which processor I better to buy to decode messages two more times faster?
