• Grails searchable plugin with hasMany

  - by user2624442

  I am using grails searchable plugin to search my domain classes. However, I cannot yet search by my hasMany (skills and interests) fields even though they are of the simple type String. This is my domain class: class EmpactUser { static searchable = [except: ['dateCreated','password','enabled','accountExpired','accountLocked','passwordExpired']] String username String password boolean enabled = true boolean accountExpired boolean accountLocked boolean passwordExpired String email String firstName String lastName String address String phoneNumber String description byte[] avatar byte[] resume Date dateCreated static hasMany = [ skills : String, interests : String, // each user has the ability to list many skills and interests so that they can be matched with a project. ] static constraints = { username blank: false, unique: true password blank: false email email: true, blank: false firstName blank: false lastName blank: false description nullable: true address nullable: true avatar nullable: true, maxSize: 1024 * 1024 * 10 resume nullable: true, maxSize: 1024 * 1024 * 10 phoneNumber nullable: true, matches: "/[(][+]d{3}[)]d+/", maxSize: 30 } } This is the code I am using to search: def empactUserList = EmpactUser.search( searchQuery, [reload: false, result: "every", defaultOperator: "or"]) Am I missing something? Thanks, Alan.

• c# .net MVC4 Model to represent table or form

  - by Matthew Chambers

  Hello I am a little confused with regards to models in mvc 4 and thought someone may be able to point me in the right direction. This would be most appreciated. For example if i have a table that has the following fields [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 5)] public string UserName { get; set; } [Required(ErrorMessage="Email Address is Required")] [StringLength(15, ErrorMessage = "Email Address must be between {0} and {1} in size",MinimumLength = 5 )] [DataType(DataType.EmailAddress)] [Display(Name="Email")] public string Email { get; set; } [MaxLength(25)] [Display(Name="Mobile Telephone Number")] public string Mobile {get;set;} [MaxLength(500)] [Display(Name="Headline")] public string Headline {get;set;} [Required] [StringLength(200)] [Display(Name = "First Name")] public string FirstName {get;set;} [Required] [StringLength(200)] [Display(Name="Surname")] public string Surname { get; set;} public virtual int? DayOfBirthId { get; set; } public virtual DayOfBirth DayOfBirth { get; set; } public virtual int? MonthOfBirthId { get; set; } public virtual MonthOfBirth MonthOfBirth { get; set; } public virtual int? YearOfBirthId { get; set; } public virtual YearOfBirth YearOfBirth{get;set;} This is my user profile table in the database. However I would like a form that the user registers to the site with. When they first register i do not need all the details such as telephone all i really need is there username, email address and password. Do i create another model for this. Or do i have one model and on the controller set the fields to null or empty string that are not required on registration. I have validation also so would this be set for data that has not been entered on the form. My question is ultimately should all forms represent models- should the database be redesigned to meet this required. Or should the controller set the values that are not required. Or should there be another model that represents the form be created which maps to this table. I am a little confused on this and clarification of anyone would be most appreciated.

• Obtaining Nearby Wifi In C Using VS2010

  - by WizardsSleeve

  Hi All, I am trying to identify a method for obtaining nearby wifi access points using C in Windows. I am coding in Visual Studio 2010. I have read the necessary documentation but am lacking in guidance on how to implement code that would accomplish this. I am specifically interested in obtaining the MAC address of nearby access points or at a minimum the MAC address of the currently connected Wifi access point. Is it possible to do this using WMI in Windows, specifically on Windows XP SP3 and later? Any pointers on how to do this are greatly appreciated.

• How to find the real problem line in my code with Application Verifier ?

  - by Newbie

  I am now trying to use this Application Verifier debugging tool, but i am stuck, first of all: it breaks the program at a line that is simple variable set line (s = 1; for example) Secondly, now when i run this program under debugger, my program seems to have changed its behaviour: i am drawing image, and now one of the colors has changed o_O, all those parts of the image that i dont draw on, has changed the color to #CDCDCD when it should be #000000, and i already set the default color to zero, still it becomes to #CDCDCD. How do i make any sense to this? Here is the output AV gave me: VERIFIER STOP 00000002: pid 0x8C0: Access violation exception. 14873000 : Invalid address causing the exception 004E422C : Code address executing the invalid access 0012EB08 : Exception record 0012EB24 : Context record AVRF: Noncontinuable verifier stop 00000002 encountered.

• Why hashCode() returns the same value for a object in all consecutive executions?

  - by Vijay Shanker

  Hi, I am trying some code around object equality in java. As I have read somewhere hashCode() is a number which is generated by applying the hash function. Hash Function can be different for each object but can also be same. At the object level, it returns the memory address of the object. Now, I have sample program, which I run 10 times, consecutively. Every time i run the program I get the same value as hash code. If hashCode() function returns the memory location for the object, how come the java(JVM) store the object at same memory address in the consecutive runs? Can you please give me some insight and your view over this issue?

• Performance problem on a query.

  - by yapiskan

  Hi, I have a performance problem on a query. First table is a Customer table which has millions records in it. Customer table has a column of email address and some other information about customer. Second table is a CommunicationInfo table which contains just Email addresses. And What I want in here is; how many times the email address in CommunicationInfo table repeats in Customers table. What could be the the most performer query. The basic query that I can explain this situation is; Select ci.Email, count(*) from Customer c left join CommunicationInfo ci on c.Email1 = ci.Email or c.Email2 = ci.Email Group by ci.Email But sure, it takes about 5, 6 minutes in execution. Thanks in Advance.

• Normalized class design and code first

  - by dc7a9163d9

  There are the following two classes. public class Employee { int EmployeeId { get; set; } public string FirstName { get; set; } public string LastName { get; set; } public string Street { get; set; } public string Street2 { get; set; } public string City { get; set; } public string State { get; set; } public string Zip { get; set; } } public class Company { int CompanyId { get; set; } public string Name { get; set; } public string Street { get; set; } public string Street2 { get; set; } public string City { get; set; } public string State { get; set; } public string Zip { get; set; } } In a DDD seminar, the speaker said the better design should be, class PersonName { public string FirstName { get; set; } public string LastName { get; set; } } class Address { public string Street { get; set; } public string Street2 { get; set; } public string City { get; set; } public string State { get; set; } public string Zip { get; set; } } public class Employee { int EmployeeId { get; set; } public PersonName Name { get; set; } [ForeignKey("EmployerAddress")] public int EmployerAddressId { get; set; } public virtual Address EmployerAddress { get; set; } } public class Company { int CompanyId { get; set; } public string Name { get; set; } [ForeignKey("CompanyAddress")] public int CompanyAddressId { get; set; } public virtual Address CompanyAddress { get; set; } } Is it the optimized design? How the code first generate the PersonName table and link it to Employee?

• Select_related() backwards relation - auto model population

  - by Nick

  Hi. If I have the following model: class Contact(models.Model) name = models.CharField(max_length=100) ... class ContactAddress(models.Model) line1 = models.CharField(max_length=100) line2 = models.CharField(max_length=100) ... contact = models.ForeignKey(Contact) I now want to grab all Contacts and for the address to be auto populated. What would be the best way to do this? The only way I have found so far is to filter out the Contacts I want and loop around each contact and assign this to Contact.addresses. I then use this for outputting each Contacts address within a template. Is there a better way of doing this? Select_related() almost does what I want, but doesn't seem to be able to work in the opposite direction. Thanks in advance for your help on this one!

• Problem with a large CSV file

  - by moustafa

  I have a very large CSV file. 51427 lines to be exact. I need to import the entire file into a MySQL database, however, the script times out due to server settings and slow connection (and maybe other reasons that I am not aware of). So - I am now passing parameters START and LIMIT via address bar to import, like this: http://my.server.address/import.php?...000&limit=1000 This reads the entire CSV file into an array, and starts at line 10000 of the array and inserts into the database until it reaches line 11000, and then terminates the script. This works very nicely, however, I am not happy having to reach the entire 51427 lines of the CSV file into an array before processing. Is there not a way where I can only read the required lines into an array? That would speed things up significantly.

• Respond to a UDP message

  - by JDCAce

  I have a pair of very simple C# programs (server and client). The client's user enters an IP address, and the client sends a UDP message to the server. The server uses UDPClient.Receive() to listen to IPAddress.Any, prints out the message it received and where it was sent from (the client's IP address), then sends a UDP message back to the client. The problem is in that last part: my client is not receiving any message. It listens only to the server, instead of IPAddress.Any. The SendUdpMessage() and WaitForMessage() methods are identical, except for the IPAddress.Any part. I cannot find what's wrong! I can post the code if I need to, but I don't know which part is relevant, and I don't want to post the entire program (about 150 lines combined).

• UIAlertView popups lock up keyboard actions

  - by TurbZ

  I have a strange behavior where if a UIAlert fires (like the one below) all subsequent keyboard or press behaviors are disabled / non responsive. Scrolling the screen still works but no action is fired from any button or keyboard presses. [[[[UIAlertView alloc] initWithTitle:@"Invalid Address" message:@"The email address you entered isn't valid. Please check and try again." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil] autorelease] show]; Anyone experienced this behavior before and can shed some light? Or maybe guide me in the right direction to debug it further to get to the root cause? Thank you heaps!

• Ubuntu 10.10 Ad-Hoc Setup (from Wireless Router, to Ubuntu Server/Desktop to Wireless Router)

  - by user60375

  Okay, so I know there are different approaches for this, but I will explain my story briefly before getting to the technical stuff. My fiancée and I are going through some financial issues (as I assume a lot of us are). We ended up having to move from our house and stay with some friends/family for 6 months, just to get ourselves caught up. (Medical bills, among other issues,etc). So this is where it gets fun. At our friends house, we are staying in the loft setup which is not near the cable modem and wireless router. I have a "hand-crafted" media center running XBMC, an Ubuntu 10.10 Server/Desktop (multi-purpose, very powerful and tons drive space), two working laptops, a between the two of us we have multiple wireless devices/phones. Now our friends Wireless router doesn't have any options for assigning IP addresses, but my router does. My current setup is: Friends Cable Modem -- Friend's Wireless Router -- Ubuntu 10.10 Server -- My Wireless Router (local-link from Friend's wireless (incoming) to sharing connection on ETH0 (outgoing)) -- to all devices. (Wireless Modem, Ubuntu Server that share's it's wireless incoming connection to the ethernet port my Wireless router share's with the rest of the devices). I setup my router to use default settings from my friend's router, using Google's DNS on my router (disabled DNS setup on Ubuntu Server), everything is assigned nicely and runs smooth. My Ubuntu server was given the address 10.42.43.1 (assuming standard from Network-Manager). (On the Ubuntu machine that shares to my wireless router; I have some server apps installed, but mainly just use Samba/NFS/Tangerine action. My problem/goal is that every device has no problem of accessing the internet from my router, the media-center has an assigned ip address, all services from all devices (ZeroConf, Avanhi, Bonjour, GIT, SSH, FTP, Apache2, etc) all work correctly except from my Ubuntu Server (which serves the wireless connection to ETH0 to another Wireless Router). The Ubuntu 10.10 Server/Desktop is not broadcasting anything (the Zeroconf Service Discovery 0.4 Gnome Applet shows the services from the Ubuntu server but no other computers can see them). I can access it from my Media-Center (Running Xbuntu 10.04) if I direct it to 10.42.43.1, no problem. But I cannot access Tangerine (Daapd) and the Samba shares do not show up on any computers for 10.42.43.1 (not in the WORKGROUP which Samba is setup simple and default but I can direct computers to that address and the shares will add except on a damn Windows 7 parition). Is this an issue with how I have my router setup and possible the gateway? An issue with Network-Manager? And issue with my Ubuntu Server/Desktop? I know there is a lot to that, but it's simpler than I probably have explained? Any help would be appreciated. If you need more details, I can provide them. If there is a better way of my attempting this home-network, please let me know. Thanks in advance for the help.

• Debian, 6rd tunnel, and connection troubles

  - by Chris B

  Long story short I am having issues with IPv6 using a 6rd tunnel with my ISP, charter business. They offer a 6rd tunnel that I think I have properly set up, but the server doesn’t reply to every ipv6 request. When the server has the network interfaces idle with no traffic for about 10 minutes, then IPv6 stops accepting inbound connections. to re-allow it, I must go into the server, and make it do a outbound ipv6 connection (normally a ping) to start it back up. Whats weird though i that if I run iptraf when its not working, it still shows a inbound ipv6 packet… the server is just not replying, and I can’t figure out why. Also, if I try to access my server over IPv6 from a house about 1 mile away on the same ISP, it is never able to connect. it always times out, but again the iptraf shows a ipv6 inbound packet. Again, it just does not reply. To test if my server is accessible through IPv6 I always have to use my vzw 4g phone (they use IPv6) or ipv6proxy dot net. Here is all of the configuration information my ISP gives on there tunnel server: 6rd Prefix = 2602:100::/32 Border Relay Address = 68.114.165.1 6rd prefix length = 32 IPv4 mask length = 0 Here is my /etc/network/interfaces for ipv6 (used x's to block real addresses) auto charterv6 iface charterv6 inet6 v4tunnel address 2602:100:189f:xxxx::1 netmask 32 ttl 64 gateway ::68.114.165.1 endpoint 68.114.165.1 local 24.159.218.xxx up ip link set mtu 1280 dev charterv6 here is my iptables config filter :INPUT DROP [0:0] :fail2ban-ssh – [0:0] :OUTPUT ACCEPT [0:0] :FORWARD DROP [0:0] :hold – [0:0] -A INPUT -p tcp -m tcp —dport 22 -j fail2ban-ssh -A INPUT -m state —state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p tcp -m multiport -j ACCEPT —dports 80,443,25,465,110,995,143,993,587,465,22 -A INPUT -i lo -j ACCEPT -A INPUT -p tcp -m tcp —dport 10000 -j ACCEPT -A INPUT -p tcp -m tcp —dport 5900:5910 -j ACCEPT -A fail2ban-ssh -j RETURN -A INPUT -p icmp -j ACCEPT COMMIT and last here is my ip6tables firewall config filter :INPUT DROP [1653:339023] :FORWARD DROP [0:0] :OUTPUT ACCEPT [60141:13757903] :hold – [0:0] -A INPUT -m state —state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p tcp -m multiport —dports 80,443,25,465,110,995,143,993,587,465,22 -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -p tcp -m tcp —dport 10000 -j ACCEPT -A INPUT -p tcp -m tcp —dport 5900:5910 -j ACCEPT -A INPUT -p ipv6-icmp -j ACCEPT COMMIT So Summary: 1.iptraf always shows IPv6 traffic, so its always making it to the server 2.server stops replying on ipv6 after no traffic for awhile (10 minutesish) until a outbound connection is made, then the process repeats. 3.server is NEVER accessable vi same ISP (yet iptraf still shows ipv6 request) Notes: When I try to access it from the same ISP from across town, even with iptables and ip6tables allowing ALL inbound traffic, this is what iptraf shows. IPv6 (92 bytes) from 97.92.18.xxx to 24.159.218.xxx on eth0 ICMP dest unrch (port) (120 bytes) from 24.159.218.xxx to 97.92.18.xxx on eth1 its strange, like its trying to forward to LAN? (eth1 is LAN, eth0 is WAN) even with the IPv6 address being set in the hosts file to the servers domain name. With iptables set up normally with the above configurations it only says this: IPv6 (100 bytes) from 97.92.18.xxx to 24.159.218.xxx on eth0 Im REALLY stuck on this, and any help would be GREATLY appreciated.

• Connecting debian and windows via IPsec VPN with Racoon and ipsec-tools

  - by Michi Qne

  I've some trouble with the IPsec configuration on my debian server (6 squeeze). This server should connect via IPsec VPN to an windows server, which is protected by an firewall. I've used racoon and ipsec-tools and this tutorial http://wiki.debian.org/IPsec. However, I am not quite sure, if this tutorial fits to my purpose, because of some differences: my Host and my gateway are the same server. So I don't have two different ip addresses. I guess, that's not a problem the other server is an windows system behind a firewall. Hopefully, not a problem the subnet of the windows system is /32 not /24. So I change it to /32. I worked through the tutorial step by step, but I wasn't able to route the ip. The following command didn't work for me: ip route add to 172.16.128.100/32 via XXX.XXX.XXX.XXX src XXX.XXX.XXX.XXX So I tried the following instead: ip route add to 172.16.128.100 .., which obviously not solved the problem. The next problem is the compression. The windows doesn't use a compression, but 'compression_algorithm none;' doesn't work with my racoon. So the current value is 'compression_algorithm deflate;' So my current result looks like this: When I am trying to ping the windows host (ping 172.16.128.100), I receive the following error message from ping: ping: sendmsg: Operation not permitted And racoon logs: racoon: ERROR: failed to get sainfo. After googling for a while I came to no conclusion, what's the solution. Does this error message mean that the first phase of IPsec works? I am thankful for any advice. I guess my configs might be helpful. My racoon.conf looks like this: path pre_shared_key "/etc/racoon/psk.txt"; remote YYY.YYY.YYY.YYY { exchange_mode main; proposal { lifetime time 8 hour; encryption_algorithm 3des; hash_algorithm sha1; authentication_method pre_shared_key; dh_group 2; } } sainfo address XXX.XXX.XXX.XXX/32 any address 172.16.128.100/32 any { pfs_group 2; lifetime time 8 hour; encryption_algorithm aes 256; authentication_algorithm hmac_sha1; compression_algorithm deflate; } And my ipsec-tools.conf looks like this: flush; spdflush; spdadd XXX.XXX.XXX.XXX/32 172.16.128.100/32 any -P out ipsec esp/tunnel/XXX.XXX.XXX.XXX-YYY.YYY.YYY.YYY/require; spdadd 172.16.128.100/32 XXX.XXX.XXX.XXX/32 any -P in ipsec esp/tunnel/YYY.YYY.YYY.YYY-XXX.XXX.XXX.XXX/require; If anyone has an advice, that would be awesome. Thanks in Advance. Greets, Michael It was a simple copy-and-paste error in an ip address.

• Postfix/SMTPD Relay Access Denied when sending outside the network

  - by David

  I asked a very similar question some 4 or 5 months ago, but haven't tracked down a suitable answer. I decided to post a new question so that I can ... a) Post updated info b) post my most current postconf -n output When a user sends mail from inside the network (via webmail) to email addresses both inside and outside the network, the email is delivered. When a user with an email account on the system sends mail from outside the network, using the server as the relay, to addresses inside the network, the email is delivered. But [sometimes] when a user connects via SMTPD to send email to an external address, a Relay Access Denied error is returned: Feb 25 19:33:49 myers postfix/smtpd[8044]: NOQUEUE: reject: RCPT from host-68-169-158-182.WISOLT2.epbfi.com[68.169.158.182]: 554 5.7.1 <host-68-169-158-182.WISOLT2.epbfi.com[68.169.158.182]>: Client host rejected: Access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<my-computer-name> Feb 25 19:33:52 myers postfix/smtpd[8044]: disconnect from host-68-169-158-182.WISOLT2.epbfi.com[68.169.158.182] Sending this through Microsoft Outlook 2003 generates the above log.

• Linux pptp client stops working after several hours

  - by Aron Rotteveel

  Here's the situation: Setup: 1 Windows Server 2008 machine acting as a Domain Controller and RRAS server 1 CentOS machine in a datacentre located elsewhere PPTP client running on CentOS machine, connected to the DC via When I connect to the DC, everything is working fine. I have set up a static IP for the dialup connection in my RRAS server so that the CentOS machine is automatically assigned the IP 192.168.1.240. Inside the VPN, it is not possible to access this machine on the local IP-address. Perfect. However, after several hours, it simply seems to stop working (IE: I cannot ping to or from this machine on the local network). The strange thing is, however: The DC shows the VPN client as still being connected The CentOS machine shows the network interface as being up There are no entries in my /var/log/messages that indicate a problem Output from ifconfig: ppp0 Link encap:Point-to-Point Protocol inet addr:192.168.1.240 P-t-P:192.168.1.160 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1396 Metric:1 RX packets:43 errors:0 dropped:0 overruns:0 frame:0 TX packets:58 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:4511 (4.4 KiB) TX bytes:15071 (14.7 KiB) Output from route -n: 192.168.1.160 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 ppp0 I have the following in my ip-up.local: route add -net 192.168.1.0 netmask 255.255.255.0 dev ppp0 The situation can be easily fixed by issueing a killall pppd and re-connecting.

• Exchange 2010 OWA - a few questions about using multiple mailboxes

  - by Alexey Smolik

  We have an Exchange 2010 SP2 deployment and we need that our users could access multiple mailboxes in OWA. The problem is that a user (eg John Smith) needs to access not just somebody else's (eg Tom Anderson) mailboxes, but his OWN mailboxes, e.g. in different domains: [email protected], [email protected], [email protected], etc. Of course it is preferable for the user to work with all of his mailboxes from a single window. Such mailboxes can be added as multiple Exchange accounts in Outlook, that works almost fine. But in OWA, there are problems: 1) In the left pane - as I've learned - we can open only Inbox folders from other mailboxes. No way to view all folders like in Outlook? 2) With Send-As permissions set, when trying to send a message from another address, that message is saved in the Sent Items folder of the mailbox that is opened in OWA, and not in the mailbox the message is sent from. The same thing with the trash can. Is there a way to fix that? Also, this problem exists in desktop Outlook when mailboxes are added automatically via the Auto Mapping feature, so that we need to turn it off and add the accounts manually. Is there a simpler workaround? 3) Okay, suppose we only open Inbox folders in the left pane. The problem is that the mailbox names shown there are formed from Display Name attributes. But those names are all identical! All the mailboxes are owned by John Smith, so they should be all named John Smith - so that letter recepient sees "John Smith" in the "from" field, no matter what mailbox it is sent from. Also, the user knows what's his name - no need to tell him. He wants to know what mailbox he works with. So we need a way to either: a) customize OWA to show mailbox email address instead of user Display Name, or b) make Exchange use another attribute to put in the "from" field when sending letters 4) Okay, we can switch between mailboxes using "Open Other Mailbox" in the upper-right corner menu. But: a) To select a mailbox we need to enter its name (or first letters). It there a way to show a list of links to mailboxes the user has full access to? Eg in the page header... b) If we start entering the first letters, we see a popup list with possible mailboxes to be opened. But there are all mailboxes (apparently from GAL), not only mailboxes the user has permission to open! How to filter that popup list? c) The same problem as in (3) with mailbox naming. We can see the opened mailbox email address ONLY in the page URL, which is insufficient for many users. In the left pane we see "John Smith" which is useless. 5) Each mailbox is tied with a separate user in AD. If one has several mailboxes, we need to have additional dummy AD accounts, create additional OUs to store them, etc. That's not very nice, is there any standartized, optimal way to build such a structure? We would really appreciate any answers or additional info for any of these questions. Thank you in advance.

• broadcom 5722 NIC not installed on Ubuntu Server, although driver present

  - by Bastien

  Hello, I just installed Ubuntu Server 10.04 LTS, running kernel 2.6.32-24-server, on a brand new Dell T110 server, supposedly fully compatible with Ubuntu Server. I have two NICs: one ONBOARD, the other additional on PCI. both of them are Broadcom netXtreme 5572. on the first boot of the system, I could see both cards as eth0 and eth1 (with ifconfig) I configured eth0 as static IP (as planned), and did not configure eth1. after rebooting, one of the two NICs "disappeared": it does not appear in ifconfig at all. the one that disappeared is the ONBOARD one. I investigated a bit and found the following things: the card is SEEN, but not "installed", it appears as "UNCLAIMED" in lshw: *-network UNCLAIMED description: Ethernet controller product: NetXtreme BCM5722 Gigabit Ethernet PCI Express vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:04:00.0 version: 00 width: 64 bits clock: 33MHz capabilities: pm vpd msi pciexpress cap_list configuration: latency=0 resources: memory:df9f0000-df9fffff *-network description: Ethernet interface product: NetXtreme BCM5722 Gigabit Ethernet PCI Express vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:05:00.0 logical name: eth0 version: 00 serial: 00:10:18:60:23:64 size: 100MB/s capacity: 1GB/s width: 64 bits clock: 33MHz capabilities: pm vpd msi pciexpress bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=tg3 driverversion=3.102 duplex=full firmware=5722-v3.09 ip=10.129.167.25 latency=0 link=yes multicast=yes port=twisted pair speed=100MB/s resources: irq:35 memory:dfaf0000-dfafffff so I checked my dmesg and found a few strange lines, showing, there actually is a problem bringing up this card: [ 3.737506] tg3: Could not obtain valid ethernet address, aborting.

I've researched everything I could on the net, and found out several people having slightly comparable issues, but they usually involve different HW, and do not provide a proper explanation / solution... I would appreciate if anyone around here has some info to share ! thanks

• Cisco ASA 5505 site to site IPSEC VPN won't route from multiple LANs

  - by franklundy

  Hi I've set up a standard site to site VPN between 2 ASA 5505s (using the wizard in ASDM) and have the VPN working fine for traffic between Site A and Site B on the directly connected LANs. But this VPN is actually to be used for data originating on LAN subnets that are one hop away from the directly connected LANs. So actually there is another router connected to each ASA (LAN side) that then route to two completely different LAN ranges, where the clients and servers reside. At the moment, any traffic that gets to the ASA that has not originated from the directly connected LAN gets sent straight to the default gateway, and not through the VPN. I've tried adding the additional subnets to the "Protected Networks" on the VPN, but that has no effect. I have also tried adding a static route to each ASA trying to point the traffic to the other side, but again this hasn't worked. Here is the config for one of the sites. This works for traffic to/from the 192.168.144.x subnets perfectly. What I need is to be able to route traffic from 10.1.0.0/24 to 10.2.0.0/24 for example.

• Windows Server 2003 RDP not listening on IPv6

  - by Ian Boyd

  i have a Windows Server 2003 machine; with IPv6 enabled: Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : newland.local IP Address. . . . . . . . . . . . : 192.168.1.244 Subnet Mask . . . . . . . . . . . : 255.255.0.0 IP Address. . . . . . . . . . . . : 2001:470:¦¦¦¦:¦¦¦¦:¦¦¦:¦¦¦¦:¦¦¦¦:¦¦¦¦ IP Address. . . . . . . . . . . . : fe80::224:1dff:fe86:fdf2%4 Default Gateway . . . . . . . . . : 192.168.1.1 fe80::250:bfff:fe91:955f%4 i can connect to IIS server using IPv, remotely and locally, using IPv4 and IPv6: > telnet 127.0.0.1 80 (connects) > telnet 192.168.1.244 80 (connects) > telnet ::1 80 (connects) > telnet fe80::224:1dff:fe86:fdf2 80 (connects) And TCPView shows that the server is listening on port 80: Note: This is useful to establish that Windows Server 2003 does have support for IPv6 services. And i can connect to terminal services, locally and remotely, using IPv4: > telnet 127.0.0.1 3389 (connects) > telnet 192.168.1.244 3389 (connects) But i cannot connect to RDP, locally or remotely, over IPv6: > telnet ::1 3389 (fails to connect) > telnet fe80::224:1dff:fe86:fdf2 3389 (fails to connect) We can see that the system is listening on 3389: Except why won't it listen on port 3389 (ipv6)? Unfortunately it's not the firewall. Aside from the fact that i'm connecting locally (in which case the firewall doesn't apply), the firewall doesn't apply:
