• A Domain Admin user doesn't have effective Administrative rights on a Domain Computer

  - by rwetzeler

  I am a developer who is setting up a virtual domain environment of testing purposes and am having trouble with the setup. I have created a new DC on a new Forest... call it dev.contoso.com. I have setup a virtual internal network for all machines that are going to be apart of this virtual test environment and have given each machine a static IP address in the 192.169.150.0 subnet. I have added machine1.dev.contoso.com to the domain dev.contoso.com. I have also provisioned a user account (adminuser) in the domain and made that user a member of Domain Admins group. Upon logging into machine1 using my newly created Domain Admin account, I cannot access/run any files on machine1. When I go into the advanced permissions for the c:\ folder and goto properties - Security Tab - Advanced - Effective Permissions and search for the dev\adminuser (mentioned above), I get an error saying: Windows can't calculate the effective permissions for admin user What do I need to do to get Administrative rights on Machine1? I am using Server 2008 R2 for both the AD controller and machine1.

• Googlebot repeatedly looks for files that aren't on my server

  - by John at CashCommons

  I'm hosting a site for a volunteer organization. I've moved the site to WordPress, but it wasn't always that way. I suspect at one point it was hacked badly. My Apache error log file has grown to 122 kB in just the past 18 hours. The large majority of the errors logged are of this form -- it's repeated hundreds of times today alone in my log files: [Mon Nov 12 18:29:27 2012] [error] [client xx.xxx.xx.xxx] File does not exist: /home/*******/public_html/*******.org/calendar.php [Mon Nov 12 18:29:27 2012] [error] [client xx.xxx.xx.xxx] File does not exist: /home/*******/public_html/*******.org/404.shtml (I verified that xx.xxx.xx.xxx was a Google server.) I suspect there was a security hole somewhere before, likely in calendar.php, that was exploited. The files don't exist anymore, but there may be many backlinks that exist that reference here, hence why googlebot is so interested in crawling them. How do I fix this gracefully? I still would like Google to index the site. I just want to tell it somehow not to look for these files anymore.

• ssh keys rejected each day

  - by EddyR

  I've had OpenSSH server running on my debian server for a couple weeks and all of a sudden now when I go to login the next day it rejects my ssh key and I have to manually add a new one each time. Not only that but I have the "tunneling with clear-text passwords" option enabled and the non-root (login with root is disabled) account for that is rejected too. I'm at a loss why this is happening and I can't find any ssh options that would explain it. --update-- I just changed debug level to DEBUG. But before that I'm seeing a lot of the following in auth.log Feb 1 04:23:01 greenpages CRON[7213]: pam_unix(cron:session): session opened for user root by (uid=0) Feb 1 04:23:01 greenpages CRON[7213]: pam_unix(cron:session): session closed for user root ...

• Package upgrade on Ubuntu raid server and grub setup issue

  - by RecNes

  I have remote Ubuntu 10.10 server running on raid system. I did package upgrade yesterday night for security reasons. During the upgrade, grub installation screen appeared and asked me which partition I wanted to install grub. Options are sda,sdb,md1 and md2. I decide to install them on both sda and sdb partitions. I wondering, was I make true decision? If machine get reboot is it can be boot up safely? You can find fdisk output and fstab mount points below: Fstab: proc /proc proc defaults 0 0 none /dev/pts devpts gid=5,mode=620 0 0 /dev/md0 none swap sw 0 0 /dev/md1 /boot ext3 defaults 0 0 /dev/md2 / ext3 defaults 0 0 Fdisk: Disk /dev/sda: 750.2 GB, 750156374016 bytes 255 heads, 63 sectors/track, 91201 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00029bb5 Device Boot Start End Blocks Id System /dev/sda1 1 262 2102562 fd Linux raid autodetect /dev/sda2 263 295 265072+ fd Linux raid autodetect /dev/sda3 296 91201 730202445 fd Linux raid autodetect Disk /dev/md0: 2152 MB, 2152923136 bytes 2 heads, 4 sectors/track, 525616 cylinders Units = cylinders of 8 * 512 = 4096 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/md0 doesn't contain a valid partition table Disk /dev/md1: 271 MB, 271319040 bytes 2 heads, 4 sectors/track, 66240 cylinders Units = cylinders of 8 * 512 = 4096 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/md1 doesn't contain a valid partition table Disk /dev/md2: 747.7 GB, 747727224832 bytes 2 heads, 4 sectors/track, 182550592 cylinders Units = cylinders of 8 * 512 = 4096 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/md2 doesn't contain a valid partition table Disk /dev/sdb: 750.2 GB, 750156374016 bytes 255 heads, 63 sectors/track, 91201 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00088969 Device Boot Start End Blocks Id System /dev/sdb1 1 262 2102562 fd Linux raid autodetect /dev/sdb2 263 295 265072+ fd Linux raid autodetect /dev/sdb3 296 91201 730202445 fd Linux raid autodetect

• How do I install the main repositories for RHEL6

  - by eisaacson

  We've setup RHEL6 on a new server. As far as we can tell, our subscription is all setup properly. However, when I run yum repolist, it doesn't show any repositories. /etc/yum.repos.d/redhat.repo is empty. I tried pasting in the content from another RHEL6 server's redhat.repo but as soon as I run yum, it wipes it out again. I just need to get the basic RedHat repositories setup so I can install packages. EDIT: Using the GUI, I went to System Administration Red Hat Subscription Manager. Under the 'Products' tab, it did not show any products. EDIT: When I run yum update, here's what I get: # yum update Loaded plugins: product-id, refresh-packagekit, security, subscription-manager This system is receiving updates from Red Hat Subscription Management. Setting up Update Process No Packages marked for Update When I log in to RedHat customer portal, it shows that subscription as active. EDIT: To make sure I wasn't having a subscription issue. I re-registered and re-subscribed. I get all the same results. # subscription-manager register --force # subscription-manager subscribe --pool=*redacted* EDIT: contents of /etc/yum.conf [main] cachedir=/var/cache/yum/$basearch/$releasever keepcache=0 debuglevel=2 logfile=/var/log/yum.log exactarch=1 obsoletes=1 gpgcheck=1 plugins=1 installonly_limit=3 contents of /etc/yum/pluginconf.d/rhnplugin.conf: [main] enabled = 0 gpgcheck = 1

• IIS 6 ASP.NET default handler-mappings and virtual directories

  - by mlauter

  I'm having a problem with setting a default mapping in IIS 6. I want to secure *.HTML files with ASP.NET forms authentication. The problem seems to have something to do with using virtual directories to hold the html files. Here's how it's setup: sample directory tree c:/inetpub/ (nothing in here) d:/web_files/my_web_apps d:/web_files/my_web_apps/app1/ d:/web_files/my_web_apps/app2/ d:/web_files/my_web_apps/html_files/ app1 and app2 both access the same html_files directory, so html_files is set as a virtual directory in the web apps in IIS... sample web directory tree //app1/html_files/ (points to physical directory: d:/web_files/my_web_apps/html_files/) //app2/html_files/ (points to physical directory: d:/web_files/my_web_apps/html_files/) If I put a file called test.html in the root of //app1/ and then add the default mapping to the asp.net dll and setup my security on the root folder with deny="?", then accessing test.html works exactly as expected. If I'm not authenticated, it takes me to the login.aspx page, and if I am authenticated then it displays test.html. If I put the test.html file in the html_files directory I get a totally different behavior. Now the login.aspx page loads and I stuck some code in to check if I was still authenticated: <p>autheticated: <%=User.Identity.IsAuthenticated%></p> I figured it would say false because why else would it bother to load the login page? Nope, it says true - so it knows i'm authenticated, but it won't give me access to the test.html file. I've spent several hours on this and haven't been able to solve it. I'm going to spend some more time on google to see if I've missed something. Fingers crossed.

• 0 connected nodes in datastax opscenter

  - by gansbrest

  Installed opscenterd on the separate node outside of the cluster, but within firewall ( aws security group ). Tested all possible ports between agents and opcenter server. No errors in the log.. 2013-10-30 01:07:23+0000 [FC_Cluster] INFO: Initializing event storage. 2013-10-30 01:07:23+0000 [FC_Cluster] INFO: Attempting to load all persisted alert rules 2013-10-30 01:07:23+0000 [FC_Cluster] INFO: Done loading persisted alert rules 2013-10-30 01:07:23+0000 [FC_Cluster] INFO: Done initializing event storage. 2013-10-30 01:07:23+0000 [FC_Cluster] INFO: Done loading persisted scheduled job descriptions 2013-10-30 01:07:23+0000 [FC_Cluster] INFO: OpsCenter starting up. 2013-10-30 01:07:23+0000 [] INFO: Finished starting new cluster services for FC_Cluster 2013-10-30 01:08:04+0000 [FC_Cluster] INFO: Agent for ip 10.34.10.185 is version u'3.2.2' 2013-10-30 01:08:04+0000 [FC_Cluster] INFO: Agent for ip 10.32.37.251 is version u'3.2.2' 2013-10-30 01:08:04+0000 [FC_Cluster] INFO: Agent for ip 10.82.226.252 is version u'3.2.2' The most interesting part that I can see some data in the opscenter UI, when I stop agents, there is no data displayed, when I start - it show up again, but at the same time it shows 0 connected nodes. Storage capacity is even funnier - 3 of 0 nodes.. Any ideas why that could be happening?

• Remote Desktop access Windows 7 system from Windows 8

  - by Prabhat

  I have 2 systems; Windows 7 & Windows 8. Both are connected to WiFi router. They have been assigned address 192.168.2.8 & 192.168.2.9 respectively. I have added them to home group. I am able to ping and connect Windows 8 system from Windows 7. I am having trouble connecting Windows 7 system from Windows 8 system. I can't even ping Windows 7 system. Windows 7 system's user is administrator (default administrator account from secpol.msc). File sharing, Remote Access, network discovery are all enabled. Someone please help me connect. EDIT : I found that this is the issue of Kaspersky Internet Security 2012. If I disable firewall, it works. I tried opening port 3389 in Kaspersky. It is still blocking access.

• ssh timeout issue connecting to an EC2 instance on OS X

  - by mamusr

  I am new to AWS and not a networking expert but curious to know more about it. I created a VPC with a public subnet only. Then i created an EC2 instance using an Ubuntu 14.04 64-bit pv AMI image (ami-e84d8480) as well generating the key pair needed to connect to it through ssh. I followed amazon's instructions to connect to an EC2 instance via ssh which did not work. Here is my attempted input and debug log: Running on OS X 10.9.4 user$ ssh -vvv -i key.pem [email protected] OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011 debug1: Reading configuration data /etc/ssh_config debug1: /etc/ssh_config line 20: Applying options for * debug1: /etc/ssh_config line 102: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to xxx.xxx.xxx.xxx [xxx.xxx.xxx.xxx] port 22. debug1: connect to address xxx.xxx.xxx.xxx port 22: Operation timed out ssh: connect to host xxx.xxx.xxx.xxx port 22: Operation timed out To attempt to resolve the issue: I enabled the SSH port. Tried different usernames other than ubuntu, like ec2-user and root. Initially set an inbound ssh rule in the security group to connect to only my ip address. When that did not work, i changed it to allow any ip to connect. But those actions did not fix the problem. Here are my guesses as to what i am missing in getting the EC2 instance connection to work. My etc/ssh_config file may be preventing the connection from taking place. I may have missed an important networking detail when setting up the VPC. I do not have a public ip address specified for the instance. I am connecting through the private ip address. My questions for the community: Am i going about it the wrong way connecting to the instance through the private ip address? if so, do i need to specify a public ip address for it to connect or some other method?

• GlusterFS on VMWare ESXi 5

  - by Dharmavir

  I want to build network file system on top of my VMWare ESXi based virtual nodes which are running Ubuntu 12.04 LTS. I am evalaluating options and found that GlusterFS (http://www.gluster.org/) can turn out to be a good choice. Purpose: I have about 2 dozen VM nodes with different configurations, on 2 physical nodes which has following configuration: 16 core Intel Xeon 1 TB 48 GB RAM Now as I said earlier each Physical server has about 1TB hdd and I can increase if I want additional so for now I have 2TB disk space available, these space is distributed in VM nodes I have created on which about 2 dozen VM nodes live. Now some of them being application server and mgmt server, they have plenty of free disk space which I want to utilize for some heavy storage which I can not design if I do that individually on single VM node. This way if my storage is distributed between dozens of VM nodes and about 2 or more physical nodes I have some sort of backup as well. I do not mind if data gets stored redundently but per my knowledge it might hapeen that individual VM nodes will not be able to store all of the data because complete data size for example if we take 100GB will exceed VM disk size of 70GB and then VM will also have system and program files on it. I need some suggestion that will GlusterFS be the solution for which I am looking forward to or I should go with something like hadoop? I am not too sure. But yes, I would like to utilize my free space on each VM node and while doing that if I get store data redundently I am okay because it will give me data security.

• attach / detach mssql 2008 sql server manager [SOLVED]

  - by Tillebeck

  An external consult wrote a guide on how to copy a database. Step two was detach the database using Sql Server Manager. After the detach the database was not visible in the SQL Server Manager... Not much to do but write a mail to the service provider asking to have the database attached again. The service porviders answer: Not posisble to attach again since the SQL Server security has been violated". Rolling back to last backup is not the option I want to use. Can any one give feedback if this seems logic and reasonable to assume that a detached database in a SQL Server 2008 accessed through SQL Server Manager cannot be reattached. It was done by rightclicking the database and choosing detach. -- update -- Based on the comments below I update the question with the server setup. There are two dedicated servers: srv1: Web server with remote desktop and an Sql Server Manager srv2: Sql server that can be accessed through the Sql Server Manager on the web server -- update2 -- After a restart of the server the DBA could suddenly do the attachment of the database. And I guess that after the restart it was a simple task. So all of your answer were rigth! It seems that I can only mark one as a correct answer so I marked the first answer correct. But all are correct answer. Thanks a lot. Without posting the link to this thread then we might had so suffer while watching our database beeing restored by a backup :-) Thanks a lot. BR. Anders

• What breaks in a Windows domain if a member has a high time skew?

  - by Ryan Ries

  It's taken for granted by most IT people that in a Windows domain, if a member server's clock is off by more than 5 minutes (or however many minutes you've configured it for) from that of its domain controller - logons and authentications will fail. But that is not necessarily true. At least not for all authentication processes on all versions of Windows. For instance, I can set my time on my Windows 7 client to be skewed all to heck - logoff/logon still works fine. What happens is that my client sends an AS_REQ (with his time stamp) to the domain controller, and the DC responds with KRB_AP_ERR_SKEW. But the magic is that when the DC responds with the aforementioned Kerberos error, the DC also includes his time stamp, which the client in turn uses to adjust his own time and resubmits the AS_REQ, which is then approved. This behavior is not considered a security threat because encryption and secrets are still being used in the communication. This is also not just a Microsoft thing. RFC 4430 describes this behavior. So my question is does anyone know when this changed? And why is it that other things fail? For instance, Office Communicator kicks me off if my clock starts drifting too far out. I really wish to have more detail on this. edit: Here's the bit from RFC 4430 that I'm talking about: If the server clock and the client clock are off by more than the policy-determined clock skew limit (usually 5 minutes), the server MUST return a KRB_AP_ERR_SKEW. The optional client's time in the KRB-ERROR SHOULD be filled out. If the server protects the error by adding the Cksum field and returning the correct client's time, the client SHOULD compute the difference (in seconds) between the two clocks based upon the client and server time contained in the KRB-ERROR message. The client SHOULD store this clock difference and use it to adjust its clock in subsequent messages. If the error is not protected, the client MUST NOT use the difference to adjust subsequent messages, because doing so would allow an attacker to construct authenticators that can be used to mount replay attacks.

• Wordpress Directory Permission to allow uploads, plugin folders, etc

  - by user1015958

  I have a wordpress pre-made site which were developed on my localmachine, and i uploaded it too a vps running on debian6, using nginx, mysql, php. Following this guide: 1) Create an unprivilaged user, this could be say 'karl' or whatever, and make them belong to the www-data group. So that if I were to login as karl and create a web root in say /home/karl/www/ , all the files will be owned by karl:www-data 2) Set up nginx as the user www-data in nginx.conf 3) Set up PHP-FPM to run as www-data 4) Place your files in /home/karl/www/[domain name maybe]/public_html/, upload as 'karl' so you don't have to chown everything again. when i type ls -l inside public_html/ it shows that all the files inside are owned by karl:karl. But the public_html directory is owned by karl:www-data. I chmod 0755 the folder wp-content but i still get the error: ERROR: Path ../wp-content/connection_images does not seem to be writeable. I know i shouldn't set it too 777 due to security reason, how should i set it too proper permission? and what should i set also to allow my users to upload,write posts,edit articles? Sorry for my english by the way.

• Java Deployment Ruleset not working

  - by adbertram

  I've created a Java Deployment Ruleset that looks like this: <ruleset version="1.0+"> <rule> <id location="http://hpfweb.mydomain.com/" /> <action permission="run" version="1.6.0_20" /> </rule> <rule> <id location="http://*.mydomain.com" /> <action permission="run" /> </rule> <rule> </ruleset> I've created a self-signed cert, added it into the keystore as well as Trusted Certification Authorities. I have an app at http://hpfweb.mydomain.com that requires Java v1.6.20 and will error out if any other version is attempted. When only this version is installed on the computer the application works. However, if a newer version is installed, it does not. As you can see, I've attempted to force the version to 1.6.0_20 in the ruleset. I've confirmed the deployment rule set is being applied successfully by going into the Java Control Panel -- Security and "view the active deployment rule set". It is exactly as you see here. I've also looked at the web source for the application and all references point to http://hpfweb* links. When the applet is launched I've brought up task manager and have confirmed the java.exe launched is coming from the jre6 directory. When the newer version is installed, I'm getting the error "accesscontrolexception - access denied (java.awt.AWTPermission.accessEventQueue".

• IIS 7 URL Rewrite to GeoServer running on Apache

  - by Maxim Zaslavsky

  I'm building a mapping application based on OpenLayers that uses GeoServer to serve up mapping data. The problem I'm having is that besides the map images I'm requesting through WMS, I'm using jQuery AJAX to get information from GeoServer. As GeoServer is running on a different port, my requests are being blocked due to cross-site scripting security policies in JavaScript. As a Java application, GeoServer runs on Apache on port 8080, while my IIS instance is running on port 80. Instead of building a proxy, I've decided to use URL Rewriting in IIS7 to fix this problem. I'm following this guide, but it's still not working. Here are my URL Rewrite rule settings: Matches URL: (.*) Condition: {HTTP_URL} matching /geoserver Action: rewrite to http://localhost:8080/{R:1}, appending query string When I request http://localhost/geoserver/wms?QUERY_LAYERS=SanDiego:FWSA_sandiego&LAYERS=SanDiego:FWSA_sandiego&SERVICE=WMS&VERSION=1.1.1&FEATURE_COUNT=20&REQUEST=GetFeatureInfo&EXCEPTIONS=application/vnd.ogc.se_xml&BBOX=-13009123.590156,3862057.2905992,-13006066.109025,3865114.7717302&INFO_FORMAT=text/html&x=20&y=20&width=40&height=40&srs=EPSG:900913, however, all I get is a 404, although the same request on port 8080 returns the proper result. What am I doing wrong? Thanks in advance.

• Authenticating Linked Servers - SQL Server 8 to SQL Server 10

  - by jp2code

  We have an old SQL Server 2000 database that has to be kept because it is needed on our manufacturing machines. It also maintains our employee records, since they are needed on these machines for employee logins. We also have a newer SQL Server 10 database (I think this is 2008, but I'm not sure) that we are using for newer development. I have recently learned (i.e. today) that I can link the two servers. This would allow me to access the employee tables in the newer server. Following the SF post SQL Server to SQL Server Linked Server Setup, I tried adding the link. In our SQL Server 2000 machine, I got this error: Similarly, on our SQL Server 10 machine, I got this error: The messages, though worded different, probably say the same thing: I need to authenticate, somehow. We have an Active Directory, but it is on yet another server. What, exactly, should be done here? A guy HERE<< said to check the Security settings, but did not say what else to do. Both servers are set to SQL Server and Windows Authentication mode. Now what?

• ISA 2006 SP1 - SSL Client Certificate Authentication in Workgroup Environment

  - by JoshODBrown

  We have an IIS6 website that was previously published using an ISA 2006 SP1 standard server publishing rule. In IIS we had required a client certificate be provided before the website could be accessed... this all worked fine and dandy. Now we wish to use a web publishing rule on ISA 2006 SP1 for this same website. However, it seems the client certificate doesn't get processed now, so of course the user can't access the website. I've read a few articles stating the CA for the certificate needs to be installed in the trusted root certificate authorities store on the ISA Server (i have done this), as well as installing the client certificate on the ISA Server (done as well). I have also verified that the ISA Server is able to access the CRL for our CA no problem... In the listener properties for the web publishing rule, under Authentication, and Client Authentication Method, there is an option for SSL Client Certificate Authentication... i select this, but it appears the only Authentication Validation Method selectable is Windows (Active Directory).... there is no Active Directory in this environment. When i configure the rule with the defaults, I then try to hit my website and it prompts for my certificate, i choose it and hit ok... then I'm given the following error Error Code: 500 Internal Server Error. The server denied the specified Uniform Resource Locator (URL). Contact the server administrator. (12202) I check the event logs on the ISA Server and in Security Logs, i see Event ID 536, Failure Aud. The reason: The NetLogon component is not active. I think this is pretty obvious since there is no active directory available. Is there a way to make this web publishing rule work using client certificates in this workgroup environment? Any suggestions or links to helpful documents would be greatly appreciated!

• Matlab computations done over Apple Filing Protocol (AFP) depend on POSIX permissions, ignores ACLs

  - by flumignan

  I'm a system administrator and have never used Matlab, so forgive my general ignorance of the program. My users have encountered problems when executing scripted Matlab actions over AFP to a Mac OS X Server 10.6.7 where the access control list (ACL) should allow actions, but the POSIX-style permissions disallow the activity. It seems as if Matlab, run locally on the Mac workstations on datasets on the remote server, ignores the ACLs entirely. This is the only application I've ever seen behave this way. The server's filesystem is HFS+J and all other activity is performing as expected. These users cannot use CIFS because of our integration with external directory systems. In this example, the directory bxdata, the members of the group cibturner should be able to modify the files. Indeed, they can using any other method except via Matlab scripts. When the Matlab script hits these files, the POSIX permissions of 644 disallow modification. It's as if the ACLs are irrelevant.

• Samba and Windows 7

  - by John Gaughan

  I built a new computer with the intention of it being primarily a home file server. Here is my setup: one desktop with Windows 7 64 HP one laptop with Windows 7 64 HP one desktop with Kubuntu 11.10 (server) The two desktops use static IPs, and I have hostnames mapped in the HOSTS files on all three systems. I have the same username/password combo on all three systems. I have been trying for a while now to set up Samba so the Windows 7 systems can see and use it. Even if I can get the server to show up, Windows is unable to log in. One of the first things I did was to enable LMv2 authentication, which this version of Samba (3.5.11) supports. The workgroup is set correctly. I can normally see the server, but cannot authenticate. Windows homegroup is turned off. Pinging between machines works fine, and the two Windows 7 systems work together flawlessly. What I am trying to do is set up Samba to use peer to peer networking using NTLM security and user-mode authentication. According to the documentation this is possible, but there are no examples that I could find. In all the googling I have done, I see a lot of people asking how to set this up but it either works for someone else and not for me (no idea what I'm missing), or it doesn't work. Has anyone gotten this to work? Is there a place I could download a smb.conf that is set up to work in this environment?

• Cisco Catalyst 3750 connected to Cisco ASA 5505 and dropping packets

  - by Bo102010

  (Cross posted from Super User per suggestion there) At the office, I have inherited a network that I am still trying to fully comprehend. I have a problem today with a new connection between: A port on a Cisco Catalyst 3750 [WS-C3750G-48TS-S running C3750-IPSERVICESK9-M version 12.2(53)SE1] A port on a Cisco ASA 5505 [ASA Software version 8.3(2)] The 3750 is home to a Vlan that has a few ports assigned to it. interface Vlan3 description Internal network (172.18.160.0/24) ip address 172.18.160.1 255.255.255.0 I have a host (outside of my control) that needs to be in this VLAN (i.e it must have an address 172.18.160.something/24) that also needs to access the Internet. To accomplish this, I ran a link from the Catalyst (Gi1/0/13) to the ASA (Ethernet 0/5). I configured the Catalyst port like so: interface GigabitEthernet1/0/13 description To ASA, 172.18.160.69 switchport access vlan 3 switchport mode access speed 100 duplex full I configured the ASA like so: interface Vlan1 nameif inside security-level 100 ip address 172.18.160.69 255.255.255.0 interface Ethernet0/5 speed 100 duplex full Then I plugged the host into Ethernet 0/4 on the ASA and instructed its owner to make its default gateway 172.18.160.69. I made a NAT rule in the ASA and set up some rules, and it's able to access the Internet without issue. However, I noticed that the Catalyst reports a ton of packets being dropped toward the ASA. Catalyst3750#show interfaces GigabitEthernet 1/0/13 | include counters|drops Last clearing of "show interface" counters 00:28:13 Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 136909347 This is a huge number of drops, since there's not much traffic on this VLAN at all. I tried these things: Make sure speed and duplex agree on both sides (100 Mbps / Full) Set no cdp enable on the Catalyst Gi10/13 Set no keepalive on the Catalyst Gi10/13 Checked for excessive CPU usage on both Checked for excessive traffic on both Am I missing something? Any help would be appreciated.

• Launch synergy client on boot in Mac OS X

  - by Herms

  I have a mac as a secondary machine at work. Currently I use synergy on my main machine to share its keyboard and mouse with the mac. I created a launch agent for my user to launch synergy when I log in, and that's working. However, this means I still have to pull out the mac's keyboard and mouse in order to log in. I tried making a user daemon so that it would launch on boot, but I get the following errors in the console: LaunchSynergy[52] Tue Jul 14 12:41:44 testmacpro.local synergyc[52] <Warning>: 3891612: (CGSLookupServerRootPort) Untrusted apps are not allowed to connect to or launch Window Server before login. LaunchSynergy[52] Tue Jul 14 12:41:44 testmacpro.local synergyc[52] <Error>: kCGErrorRangeCheck : On-demand launch of the Window Server is allowed for root user only. LaunchSynergy[52] Tue Jul 14 12:41:44 testmacpro.local synergyc[52] <Error>: kCGErrorRangeCheck : Set a breakpoint at CGErrorBreakpoint() to catch errors as they are returned LaunchSynergy[52] _RegisterApplication(), FAILED TO establish the default connection to the WindowServer, _CGSDefaultConnection() is NULL. Is there a way to get this to work? Looks like the Mac's security doesn't want to allow anything to take control of the window while at the login screen. I can understand that, but I'd like a way to override it, as it would make my life a lot easier.

• cannot log into mysql locally

  - by Lostsoul

  When I try to log into mysql locally using the command: mysql -u root -p I get this error: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) I can access the server remotely(not as root) and my web pages are using the mysql fine, but locally I cannot log on(which I need because I need to create some users). Only change I made was to attach another drive to the server and move the sql data there. Here's my.cnf [mysqld] datadir=/media/ephemeral0/data/mysql socket=/media/ephemeral0/data/mysql/mysql.sock user=mysql # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 # adding more config skip-external-locking long_query_time=1 slow_query_log slow_query_log_file=/var/log/log-slow-queries.log log-bin=mysql-bin server-id= 1 [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid myisam_recover_options I read I need to edit the socket info in my.cnf to make sure it points to the right socket file..I double checked and the file exists(although it starts with an S when I do ls -l "srwxrwxrwx 1 mysql mysql 0 Jun 21 03:43 mysql.sock"). I'm not really sure how to resolve this. I have tried to reboot and ran yum update to make sure I was running the latest packages. Please help!
