  • Virtual Wifi Issue Windows 7

    - by Matt
    Lately I've been trying to use my laptop as a wireless router in my room. I have it connected to my school's network through ethernet, and I want to set up wireless so that I can use Wifi on my Android phone and iPod Touch. In the past, I used Connectify, but I started having an issue where my phone would find the network, connect, attempt to get the IP, and then suddenly the network would disappear. Then it'd pop up again, and the same process would happen over and over. I decided that I'd totally uninstall Connectify, but after that, neither Virtual Router Manager nor the command prompt could create a viable network either. My phone and even my iPod now encounter the same problem. Neither can successfully connect. So evidently there is something wrong with the laptop's virtual wifi feature, and I have no idea what that could be. I've tried enabling certain services that virtual wifi supposedly relies on, but some of them don't start, namely Remote Access Connection Manager. But I also have read that these enable on their own and that if they are normally not enabled it's fine. Furthermore, I even uninstalled and reinstalled the drivers for my wireless card. Any ideas as to why my virtual wifi won't function? Anything? I really would love to get this working...

  • Which ports are needed for NTLM (Windows Authentication) to connect to SQL Server?

    - by Adam Bellaire
    I've got SQL server running on a machine which is not in a domain, and which is not operating in mixed mode (it's running with "Windows Authentication"). I'm trying to connect to it from a Linux web server running freetds via TCP/IP, using NTLM to authenticate. The firewall on the SQL server is very restrictive. 1433 is open to my web server, but I'm getting conflicting information from the web on what additional ports (TCP/UDP) are needed for NTLM to succeed. It is currently fail; I can talk on 1433 to request NTLM, but the actual authentication always fails. One source says 137, 138, 139, but those are just the NetBIOS ports. Do I really need those? Another source says 135. Still others seem to say 1434... I can't make heads or tails of it. Dammit Jim, I'm a programmer, not a network administrator! EDIT: The exact error message: Msg 18452, Level 14, State 1, Server , Line 0 Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection. Msg 20002, Level 9, State -1, Server OpenClient, Line -1 Adaptive Server connection failed I am attempting to connect with a remote machine username, i.e. 'servername\username'. Some sources recommend that I set up mirrored accounts on the local and remote machines, but the local machine is running Linux, not IIS under Windows.

  • Problems with X11GraphicsDevice on Suse 11

    - by Daniel
    Hi, On servers running Suse 11 I'm experiencing hangups in sun.awt.X11GraphicsDevice.getDoubleBufferVisuals(Native Method) when connecting via Citrix (and setting DISPLAY to localhost:11.0). Running exactly the same code in exactly the same environment, excepth through Exceed (with DISPLAY set to my workstation's IP) it runs like clockwork. The error is not intermittent, it happens every time Reinstalling the OS does not help Can not reproduce it on Suse 10 This is what the main thread stack looks like: [junit] "main" prio=10 tid=0x0000000040112000 nid=0x6acc runnable [0x00002b9f909ae000] [junit] java.lang.Thread.State: RUNNABLE [junit] at sun.awt.X11GraphicsDevice.getDoubleBufferVisuals(Native Method) [junit] at sun.awt.X11GraphicsDevice.makeDefaultConfiguration(X11GraphicsDevice.java:208) [junit] at sun.awt.X11GraphicsDevice.getDefaultConfiguration(X11GraphicsDevice.java:182) [junit] - locked <0x00002b9fed6b8e70 (a java.lang.Object) [junit] at sun.awt.X11.XToolkit.(XToolkit.java:92) [junit] at java.lang.Class.forName0(Native Method) [junit] at java.lang.Class.forName(Class.java:169) [junit] at java.awt.Toolkit$2.run(Toolkit.java:834) [junit] at java.security.AccessController.doPrivileged(Native Method) [junit] at java.awt.Toolkit.getDefaultToolkit(Toolkit.java:826) [junit] - locked <0x00002b9f94b8ada0 (a java.lang.Class for java.awt.Toolkit) [junit] at java.awt.Toolkit.getEventQueue(Toolkit.java:1676) [junit] at java.awt.EventQueue.invokeLater(EventQueue.java:954) [junit] at javax.swing.SwingUtilities.invokeLater(SwingUtilities.java:1264) ...

  • ASA Slow IPSec Performance with Inconsistent Window Size

    - by Brent
    I have a IPSec link between two sites over ASA 5520s running 8.4(3) and I am getting extremely poor performance when traffic passes over the IPSec VPN. CPU on the devices is ~13%, Memory at 408 MB, and active VPN sessions 2. The load on both of the the devices is particularly low. Latency between the two sites is ~40ms. Screenshot of wireshark file transfer between the two hosts over the firewall IPSec VPN performing at 10MBPS. Note the changing window size. http://imgur.com/wGTB8Cr Screenshot of wireshark file transfer between the two hosts over the firewall not going over IPSec performing at 55MBPS. Constant window size. http://imgur.com/EU23W1e I'm showing an inconsistent window size when transferring over the IPSec VPN ranging in 46,796 to 65535. When performing at 55+MBPS, the window size is consistently 65,535. Does this show a problem in my configuration of the IPSec VPN in the ASA or a Layer1/2 issue? Using ping xxxxxx -f -l I finally get a non-fragment at 1418 bytes so 1418+28 for IP/ICMP headers = 1446. I know that I have 1500 set on the ASA and Ethernet. I do have "Force Maximum segment size for TCP proxy connection to be" "1380" bytes set under Configuration Advanced TCP Options on the ASA. Using IPERF, I am getting a "TCP Window Full" every few seconds and ~3 MBPS performance. http://imgur.com/elRlMpY Show Run on the ASA http://pastebin.com/uKM4Jh76 Show cry accelerator stats http://pastebin.com/xQahnqK3

  • Amazon VPC NAT not working

    - by rpkelly
    I'm trying to create a NAT instance for my VPC to allow instances on private subnets connect to the internet (most importantly, S3). I tried following the instructions here: http://docs.amazonwebservices.com/AmazonVPC/2011-07-15/UserGuide/index.html?VPC_NAT_Instance.html . Unfortunately, the instances in the private subnet (call it 10.10.2.0/24) cannot reach the internet. I have done the following: Create a NAT instance (Amazon's ami-vpc-nat-1.0.0-beta.i386-ebs (ami-d8699bb1)) in public subnet (call it 10.10.1.0/24). Changed "Source / Dest Check" to disabled. Created a new entry in the default routing table (which is used by 10.10.2.0/24) and had it point to the ID of the newly created instance. Associated an Elastic IP address with the NAT instance. Allowed all outbound traffic on the security group of the NAT instance. Ensured that all traffic could pass between the two subnets. I've tried also doing this with an existing instance using iptables, but had no luck. And I have verified that sys.net.ipv4.ip_forward is 1, just in case anyone was wondering. And I still have no internet connectivity from the instances on 10.10.2.0/24. Does anyone have any suggestions?

  • Using "route add" to tell my computer to use a direct ethernet connexion instead of wifi ?

    - by TheSamFrom1984
    2 PCs are involved. Both are connected to the internet via Wifi on the same router. I can ping to/from each other and share folders flawlessly, but I'd like to be able to set a direct Ethernet link between them to speed up file transfers AND keep the Wifi connections (no gateway). So I plugged my RJ45 cable, and set up the connection. It works, but the PCs are only using this connection if one of them if disconnected from the Wifi. PC1 local address is 192.168.0.7 on its ethernet interface, and 192.168.1.21 on the wifi one. PC2 local address is 192.168.0.6 on its ethernet interface, and 192.168.1.22 on the wifi one. My question is : I'd like to using the route add command to tell PC1 to use the Ethernet interface when it needs to connect with PC2, by specifying "IF 2" at the end of the route add command. How can I do this ? I don't know what to put in the "gateway" parameter of the command, and everything I tried returns "the parameter is incorrect" (i don't know which one). ipconfig /all on PC1 : Windows IP Configuration Host Name . . . . . . . . . . . . : Sam-PC Primary Dns Suffix . . . . . . . : Node Type . . . . . . . . . . . . : Hybrid IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No Wireless LAN adapter Wireless Network Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : NETGEAR WG111v3 54Mbps Wireless USB 2.0 Adapter Physical Address. . . . . . . . . : 00-22-3F-DA-51-56 DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes Link-local IPv6 Address . . . . . : fe80::1d33:60b:476c:d396%12(Preferred) IPv4 Address. . . . . . . . . . . : 192.168.1.21(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Lease Obtained. . . . . . . . . . : vendredi 27 novembre 2009 15:38:48 Lease Expires . . . . . . . . . . : dimanche 29 novembre 2009 07:33:04 Default Gateway . . . . . . . . . : 192.168.1.1 DHCP Server . . . . . . . . . . . : 192.168.1.1 DHCPv6 IAID . . . . . . . . . . . : 301998655 DHCPv6 Client DUID. . . . . . . . : 00-01-00-01-12-7E-58-EA-00-1A-4D-59-B2-71 DNS Servers . . . . . . . . . . . : 192.168.1.1 NetBIOS over Tcpip. . . . . . . . : Enabled Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Realtek PCIe GBE Family Controller Physical Address. . . . . . . . . : 00-1A-4D-59-B2-71 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes Link-local IPv6 Address . . . . . : fe80::f598:c3a0:df8d:706e%11(Preferred) IPv4 Address. . . . . . . . . . . : 192.168.0.7(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : DHCPv6 IAID . . . . . . . . . . . : 234887757 DHCPv6 Client DUID. . . . . . . . : 00-01-00-01-12-7E-58-EA-00-1A-4D-59-B2-71 DNS Servers . . . . . . . . . . . : fec0:0:0:ffff::1%1 fec0:0:0:ffff::2%1 fec0:0:0:ffff::3%1 NetBIOS over Tcpip. . . . . . . . : Enabled

  • DNS, subdomain, and IPv6 -- possible to add subdomain.example.com NS record to an IPv6 host?

    - by mpbloch
    example.com is listed with a registrar -- specifically, answerable.com. I want to host a subdomain in-house, specifically home.example.com. I am using an ipv6 gateway, specifically gogo6, to have a public IPv6 address. The IP address looks like 2001:xxxx:xx47. Then http://[2001:xxxx:xx47] goes to my test site (an instance of IIS7). I can add a quad-A record for my primary site -- home.example.com AAAA 2001:xxxx:xx47. Then http//home.example.com loads correctly. Must I add an A or quad-A record for all sub.home.example.com to my answerable.com DNS manager for example.com? Or can I delegate DNS queries to *.home.example.com to the machine at [2001:xxxx:xx47]? I have tried to add a AAAA record for tunnel.example.com to [2001:xxxx:xx47], and then add an NS entry for home.example.com to tunnel.example.com, but browsing then results in "DNS lookup error" from my browser. Is this a configurable scenario? Can DNS for subdomain only be delegated to IPv4 addresses?

  • Subdomains and address bar

    - by Priednis
    I have a fairly noob question about how subdomains work. As I understand at first the DNS server specifies that a request for certain subdomain.domain.com has to go to the IP address of domain.com, and the webserver at domain.com further processes the request and displays the needed subdomain page. It is not entirely clear to me how (for example Apache) server does it. As I understand there can be entries in vhosts.conf file which specify folders that contain the subdomain data. Something like: <VirtualHost *> ServerName www.domain.com DocumentRoot /home/httpd/htdocs/ </VirtualHost> <VirtualHost *> ServerName subdomain.domain.com DocumentRoot /home/httpd/htdocs/subdomain/ </VirtualHost> and there also can be redirect entries in .htaccess files like rewritecond %{http_host} ^subdomain.domain.com [nc] rewriterule ^(.*)$ http://www.domain.com/subdomain/ [r=301,nc] however in this case the user gets directed to the directory which contains the subdomain data but the user gets "out" of the subdomain. I would like to know - how, when going to subdomain.domain.com the subdomain.domain.com, beginning of address remains visible in the address bar of the explorer? Can it be done by an alternate entry in .htaccess file? If a VirtualHost entry is specified in the vhosts.conf file, does it mean, that a new user account has to be specified for access to this directory?

  • debian VM refusing all traffic apart from http

    - by james lewis
    I've got a VM with a fresh install of Debian (wheezy) and I've installed node and mongo on it. The VM is using a bridged network connection so I was expecting to be able to point my host machines browser at the ip address of the Debian VM (port 1337 for my node example or port 28017 for my mongo status page) and see one of the two services (node or mongo). My requests are refused though. As far as I can tell Debian allows all traffic by default and you have to manually configure iptables to drop traffic. I've checked iptables and it says it's setup to allow anything through. It looks like this: root@devbox:/home/jlewis# iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination As a test I setup nginx and I was able to get to the nginx landing page from my host no problems so obviously http traffic is allowed. I then set nginx up to forward all traffic upstream to mongo - no problems there, I was able to see the status page. I then did the same for my example node server and again, no problems. So http traffic is fine, but all other traffic is blocked. Anyone know why debian might be refusing all other traffic other than iptables being setup to drop it?

  • Postfix Whitelist before recipient restrictions

    - by GruffTech
    Alright. Some background. We have an anti-spam cluster trucking about 2-3 million emails per day, blocking somewhere in the range of 99% of spam email from our end users. The underlying SMTP server is Postfix 2.2.10. The "Frontline defense" before mail gets carted off to SpamAssassin/ClamAV/ ect ect, is attached below. ...basic config.... smtpd_recipient_restrictions = reject_unauth_destination, reject_rbl_client b.barracudacentral.org, reject_rbl_client cbl.abuseat.org, reject_rbl_client bl.mailspike.net, check_policy_service unix:postgrey/socket ...more basic config.... As you can see, standard RBL services from various companies, as well as a Postgrey service. The problem is, I have one client (out of thousands) who is very upset that we blocked an important email of theirs. It was sent through a russian freemailer who was currently blocked in two of our three RBL servers. I explained the situation to them, however they are insisting we do not block any of their emails. So i need a method of whitelisting ANY email that comes to domain.com, however i need it to take place before any of the recipient restrictions, they want no RBL or postgrey blocking at all. I've done a bit of research myself, http://www.howtoforge.com/how-to-whitelist-hosts-ip-addresses-in-postfix seemed to be a good guide at first, almost fixing my problem, But i want it to accept based on TO address, not originating server.

  • setting up subdomain wildcard: configured A record, VirtualHost... still does not work

  • DNS NAmeserver Aname and cname records

    - by David
    Hi - I am inexperienced in the configuration of DNS and have an issue with dominan hosting set up. I have two domains 'www.mydomain1.com' and 'www.mydomain2.com', with mydomain2 pointed at the same place as mydomain1. The domains were passed to me recently by the person who previoulsy controlled them. I have an account with fasthosts in the uk. When I accepted the domains I could not access the DNS settings and enquired with fasthosts as to why. The replied saying 'The delegate hosting option for both domains were enabled and this is the reason why you were unable to find the option to edit the advanced DNS records. I have now disabled the delegate hosting option so you can now edit the advanced DNS records for both domains in your account.' When i log into the fasthost control panel now i can access the DNS controls but both domains have no A Record of Cname record set up. I am concerned that fasthosts have blatted the previous Nameserver entries and set me up on theirs but not added any record. 'www.mydomain1.com' currently still works but 'www.mydomain2.com' does not find the site anymore. i am worried i will lose mydomain1 to as teh dns changes filter through the system. my webhosting is at 'xxx.xxx.xxx.xxx/mydomain1.com/' and this is where I want both domains to point. Any advice would be much appreciated. one thing which is confusing me is that because I am on a shared server I have to put 'xxx.xxx.xxx.xxx/mydomain1.com/' to get to my site rather than just 'xxx.xxx.xxx.xxx'. The form on fasthosts for the aname record only allows an IP to be entered - does it add the mydomain1.com/ onto the end itself? Thanks for any help given - I'm quite worried about this David

  • Why am I seeing MailSlot Browse messages on unrouted ports of my Linux box?

    - by nmichaels
    I have a Linux box (Debian squeeze) with several NICs. The ones of interest are: eth3 - my main link to the network (dhcp on 10.20.30.0/24) eth0 - the first connection to my test network (static: 192.168.1.2) eth4 - the second connection to my test network (static: 192.168.1.1) My routing table looks like this: $ sudo route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.20.30.0 * 255.255.255.0 U 0 0 0 eth3 default 10.20.30.254 0.0.0.0 UG 0 0 0 eth3 I have the 2 test net ports connected to each other with a crossover cable and an instance of wireshark running on each port. Every once in a while, I'll see a packet like the following show up. Who could be doing this, and how do I convince them to stop? I do have Samba running on the machine (for a cifs mount) but don't see why it would be sending packets out to unrouted ports. I had a Windows VM running in VMWare Client and thought that might be causing it, but it still happens without it. What I want is totally silent interfaces so I can run some tests with Scapy over them.

  • OpenBSD logins via SSH seem to be ignoring my configured radius server

    - by Steve Kemp
    I've installed and configured a radius server upon my localhost - it is delegating auth to a remote LDAP server. Initially things look good: I can test via the console: # export user=skemp # export pass=xxx # radtest $user $pass localhost 1812 $secret Sending Access-Request of id 185 to 127.0.0.1 port 1812 User-Name = "skemp" User-Password = "xxx" NAS-IP-Address = 192.168.1.168 NAS-Port = 1812 rad_recv: Access-Accept packet from host 127.0.0.1 port 1812, id=185, Similarly I can use the login tool to do the same thing: bash-4.0# /usr/libexec/auth/login_radius -d -s login $user radius Password: $pass authorize However remote logins via SSH are failing, and so are invokations of "login" started by root. Looking at /var/log/radiusd.log I see no actual log of success/failure which I do see when using either of the previous tools. Instead sshd is just logging: sshd[23938]: Failed publickey for skemp from 192.168.1.9 sshd[23938]: Failed keyboard-interactive for skemp from 192.168.1.9 port 36259 ssh2 sshd[23938]: Failed password for skemp from 192.168.1.9 port 36259 ssh2 In /etc/login.conf I have this: # Default allowed authentication styles auth-defaults:auth=radius: ... radius:\ :auth=radius:\ :radius-server=localhost:\ :radius-port=1812:\ :radius-timeout=1:\ :radius-retries=5:

  • Tell postfix to merge three Authentication-Results:-Lines into one?

    - by Peter
    I am running a postfix mta with debian wheezy. I am using postfix-policyd-spf-python, openkdim and opendmarc. When receiving e-mails from google (google apps with own domain) for example, the header looks like this: [...] Authentication-Results: mail.xx.de; dkim=pass reason="1024-bit key; insecure key" header.d=yyy.com [email protected] header.b=OswLe0N+; dkim-adsp=pass; dkim-atps=neutral<br> [...] Authentication-Results: mail.xx.de; spf=pass (sender SPF authorized) smtp.mailfrom=yyy.com (client-ip=2a00:1450:400c:c00::242; helo=mail-wg0-x242.google.com; [email protected]; [email protected]) [...] Authentication-Results: mail.xx.de; dmarc=pass header.from=yyy.com<br> [...] This means any of these programs creates it's own Authentication-Results:-Line. Is it possible to tell postfix to merge this into one single Authentication-Results:-Line? When I send an e-mail to google, it says: [...] Authentication-Results: mx.google.com; spf=pass (google.com: domain of [email protected] designates xxx.xxx.xxx.xxx as permitted sender) [email protected]; dkim=pass [email protected]; dmarc=pass (p=NONE dis=NONE) header.from=xxx.com [...] And this is exactly what I want. Just one Authentication-Results-Header. How can I do this? Thanks. Regards, Peter

  • Hubs/switches taking out switches?

    - by Bart Silverstrim
    Here's the issue...we have a network with a lot of Cisco switches. Someone plugged in a hub on the network, and then we started seeing "weird" behavior; errors in communication between clients and servers, or network timeouts, dropping network connections, etc. It seemed that somehow that hub (or SOHO switch) was particularly freaking out our Cisco 3700 series switches. Disconnect that hub or netgear-type SOHO switch and things settled down again. We're in the process of trying to get a centralized logging server for SNMP and management, etc., to see if we can trap errors or narrow down when someone does this sort of thing without our knowledge because things seem to work, for the most part, without issue, we just get freaky oddball incidents on particular switches that don't seem to have any explanation until we find out someone decided to take matters into their own hands to expand available ports in their room. Without getting into procedure changes or locking down ports or "in our organization they'd be fired" answers, can someone explain why adding a small switch or hub, not necessarily a SOHO router (even a dumb hub apparently caused the 3700's to freak out) sending DHCP request out, will cause issues? The boss said it's because the Cisco's are getting confused because that rogue hub/switch is bridging multiple MAC's/IP's into one port on the Cisco switches and they just choke on that, but I thought their routing tables should be able to handle multiple machines coming into the port. Anyone see that behavior before and have a clearer explanation of what's happening? I'd like to know for future troubleshooting and better understanding that just waving my hand and saying "you just can't".

Below is the filesystem of server A and server B - server A [root@AVDVD-Filer ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_avdvdfiler-lv_root 16T 14T 1.5T 91% / tmpfs 3.0G 0 3.0G 0% /dev/shm /dev/cciss/c0d0p1 194M 23M 162M 13% /boot /dev/mapper/vg_avdvdfiler-test 2.3T 201M 2.1T 1% /test /dev/sr0 3.3G 3.3G 0 100% /mnt server B [root@localhost ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup-LogVol00 20G 2.5G 16G 14% / tmpfs 3.0G 0 3.0G 0% /dev/shm /dev/cciss/c0d0p1 194M 23M 162M 13% /boot /dev/mapper/VolGroup00-LogVol00 16T 133M 15T 1% /xiangao/lv1 /dev/mapper/VolGroup00-LogVol01 4.7T 190M 4.5T 1% /xiangao/lv2 I want to copy LVM volume /dev/mapper/vg_avdvdfiler-lv_root on server A to LVM volume /dev/mapper/VolGroup00-LogVol00 on server B . The server A and server B is in the same IP segment. IN the LVM volume on server A , there is all average 500M avi wmv mp4 etc. I tried mount /dev/mapper/vg_avdvdfiler-lv_root on server A to server B through NFS , then use cp command copy. It is clear I faild . Because the LVM volume is too big , I do not have good idea . I hope a good solution here. I'm a chinese, my english is very pool. sorry thanks everyone!

  • Loop through several servers, find specific dlls , get the dll version, internal filename and path?

    - by Graham
    I am a newby to Powershell, and using PS v2. I can see the massive potential it has, but I just can't get the following code to work fully. I am trying to end up with a csv file that contains the wild carded required dlls in the GAC_MSIL or sub-directory, get the dll version, internal filename and path, and the server IP address. The code is below, and it is in single line format because it appears easier to remote onto one of the servers in the server farm and run the single line from that console, ue to security log-ins etc. The code has produced a set of results, but only for the last server, it probably does the first server, then overwrites it but I am not sure about that. I have done a lot of reading about using arrays, and custom objects, and had a go at doing that, but my scripting skills in PS are not yet up to it. Code: $out = "Ouput_dll_ver_results.csv";foreach ($server in '11.222.33.123', '11.222.33.124') {$VersionInfo = (Get-ChildItem \$server\C$\windows\assembly\GAC_MSIL -recurse -Include abc*.dll,def*.dll,ghi*.dll,jkl*.dll | Where-Object { $.FullName -notmatch "\windows\assembly\temp\" })}; $VersionInfo | %{Get-Command $.FullName} | select -expand File* |Export-Csv $out Can you please advise if/how the above code can be corrected, and if not, what alternatives do I have to get the information I need. Many thanks in advance. Graham

  • Running git-svn with cron results in garbage in .git

    - by Paul
    I've setup a git-svn repo with cron to fetch from the svn repo daily. I have a script to do the fetching, and this is what is invoked by cron. Everything is fine with the repo, and the script works fine when executed manually. However, when it runs under cron, empty files get dropped into the .git directory. The files have names that look like they are some base64 output, e.g. juTrvjP6m8 and kcKf3hu3b4. Two of these files show up for every cron run. I thought these might be commit hashes, but they're not, git-show says it's an unknown revision. I set-up the repo as follows: git svn init http://svn.ip.addr/repo git svn fetch svn-remote My script looks like this: cd /gitsvn/dir git svn fetch svn-remote git svn push pub The last line pushes the repo to a separate (bare) public repo from which others can clone. I'm piping the output from the cron job to a file, which looks like this: fatal: unable to run 'git-svn' Counting objects: 21, done. Delta compression using up to 2 threads. Compressing objects: 100% (10/10), done. Writing objects: 100% (11/11), 59.08 KiB, done. Total 11 (delta 8), reused 0 (delta 0) To /gitpub/repo.git 360faf5..a153b0d trunk -> trunk The line "fatal: unable to run 'git-svn'" is alarming, but the fetch seems to go ahead anyway. Any suggestions? Where are these empty garbage files coming from, and how to stop them? Am I in for bigger problems in the future? BTW, I'm using git 1.6.3.3.

  • Specific DNS sometimes resolves to wildcard, incorrectly

    - by Mojo
    I have an intermittent problem, and I'm not sure where to start trying to troubleshoot it. In our dev environment, we have two visible IP addresses on load balancers, one to the front-end, and one to a number of back-end service machines. The front-end is configured to take a wildcard DNS name to support generic "portals." dev.example.com A 10.1.1.1 *.dev.example.com CNAME dev.example.com The back-end servers are all specific names within the same space: core.dev.example.com A 10.1.1.2 cms.dev.example.com CNAME core.dev.example.com search.dev.example.com CNAME core.dev.example.com Here's the problem. Periodically a developer or a program trying to reach, say, cms.dev.example.com will get a result that points to the front-end, instead of the back-end load balancer: cms.dev.example.com is an alias to core.dev.example.com core.dev.example.com is an alias to dev.example.com (WRONG!) dev.example.com 10.1.1.1 The developers are all on Mac OS X machines, though I've seen the problem occur on an Ubuntu machine as well, using a local cloud host DNS resolver. Sometimes the developer is using a VPN, which directs the DNS to its own resolver, and sometimes he's on the local net using a DNS resolver assigned by the NAT router. Sometimes clearing the Mac OS X DNS cache, logging into the VPN, then logging out of the VPN, will make the problem go away. The origin authoritative server is on zerigo, and a dig directly to their name servers always seems to give the correct answer. The published DNS cache time for these records is 15 minutes, but the problem has been intermittent for about a week. Any troubleshooting suggestions?

  • Windows XP can use a wired network port, but MacBook (OS X) fails on the same port

    - by Dean Hill
    I wired the Cat5 in my house seven years ago. The wired ports have worked fine with both my Windows XP laptop and MacBook. My wireless network also works fine, but I like to use wired occasionally. One of the Cat5 runs wasn't terminated with a jack, so I recently terminated this wire with a port/jack on the wall end and a standard Cat5 plug on the end that plugs into my router. This is the same setup as my other runs. Unfortunately, the MacBook isn't working well with the new wired port. The OS X Network System Preferences show the IP, Subnet, Router, etc., and everything looks fine. A "netstat -ibd" shows no errors or dropped packets. However, when I open a page in Safari, the status says "Contacting 'www.google.com'" and appears to hang. If I wait for a couple minutes, part of the Google page starts to display, but it is still not the full page load. When I use a Windows XP laptop on the same wired port, everything works fine. An internet speed test shows good results and all web pages load fine. A "netstat -e" under Windows shows no errors. I've used a Cat5 tester, and the cable tests fine (wires 1-8 light up in sequence). I've replaced both the port/jack and the connector twice to make sure I wired things correctly. I'd really like this Cat5 to work with the MacBook (and I'm trying to avoid running a new length of cable). Any ideas what the problem could be?

  • arp requests are sent continuously and my linux machine disconnected to the world

    - by sees
    I have the following problem and really need your help I'm implementing a small server to receive request from client on port 18999(just sample) using TCP socket. When I tested my server by using a lot of requests from a tablet through a router, I got the ARP problem(?) My net work just like: TABLET <------- WIRELESS ROUTER <------- MY SERVER (LINUX) Problems: 1. Can not connect to my Linux any more ( telnet, ping v.v...unreachable) 2. I use serial cable to connect to my Linux machine and use Wiresharp (from Windows) to catch the send message from Linux. It says that Linux keeps sending out continuously every 3 seconds ARP messages like the following: xx:xx:99:77:ff:69 ff:ff:ff:ff:ff:ff ARP 60 Who has 192.168.10.2? Tell 192.168.10.3 In the above message: xx:xx:99:77:ff:69 my Linux MAC address 192.168.10.2 my Tablet address 192.168.10.3 my Linux IP address Can you help me figure out the problem? Or tell me the way to detect the problem and reset the network back to normal (maybe restart Linux but I want to detect problem and restart automatically) UPDATE: 1. The above network works normally if tablet sends messages to my LINUX in normal speed (but also down after 48 hours) 2. The router works again after I unplugged my Linux ethernet cable (RJ45) from router. 3. The wireless network still works ( I can browser the router page from tablet) 4. When I use: ifconfig down then ifconfig up , the Linux restarts (?????????)

  • Host spreads wrong MAC Adress of router on the WIFI

    - by JavaIsMyIsland
    Strange things are going on our network. Since yesterday a host which is actually not on our subnet spreads wrong ARP Replys on our network. To be precise, only on the WIFI. If I connect my Laptop to the cable ethernet, it gets the right MAC adress of the router. Also my Android phone and my Ubuntu system do get the right MAC Adress. So I took a look at wireshark. When I clear the ARP cache of the windows machine, the first ARP response is correct and comes from the router. But like 10 ms later another ARP response comes from another host in the WIFI. The host changes its IP Adresses from time to time and they look like they are not on our subnet. So I can not use the internet because DNS is not working anymore. Sometimes the router wins the race condition and the mac adress is set correctly in the arp cache. I first thought, this is an arp-poisoning mitm attack but it does not make sense if the packets get not routed correctly?! I restarted the router but it didn't help. I have no access to the router, else I would change the shared key to make sure there is no intruder on the wifi.

  • Throughput; capacity planning help for C10K like design

    - by z8000
    I am designing a network service in which clients connect and stay connected -- the model is not far off from IRC less the s2s connections. I could use some help understanding how to do capacity planning, in particular with the system resource costs associated with handling messages from/to clients. There's an article that tried to get 1 million clients connected to the same server [1]. Of course, most of these clients were completely idle in the test. If the clients sent a message every 5 seconds or so the system would surely be brought to its knees. But... How do you do less hand-waving and you know, measure such a breaking point? We're talking about messages being sent by a client over a TCP socket, into the kernel, and read by an application. The data is shuffled around in memory from one buffer to another. Do I need to consider memory throughput ("5 GT/s" [2], etc.)? I'm pretty sure I have the ability to measure the basic memory requirements due to TCP/IP buffers, expected bandwidth, and CPU resources required to process messages. I'm a little dim on what I'm calling "thoughput". Help! Also, does anyone really do this? Or, do most people sort of hand-wave and see what the real world offers, and then react appropriately?
