• SSH disconnects active session after 20 minutes

  - by Paramaeleon

  I’ve just set up a new Linux box (OpenSuSE 12.3 on VmWare). Now I stated that my SSH shell sessions are disconnected exactly after 20 minutes, clearly with activity. (Putty: “Network error: Software caused connection abort”) I already set Putty to send keep alives every 64 sec. In sshd_config, I set ClientAliveInterval 50 ClientAliveCountMax 2 and did a deamon reload. Didn’t help. About two minutes after the link breakdown, ssh reports to /var/log/messages: … … sshd[…]: Timeout, client not responding. … … sshd[…]: pam_unix(sshd:session): session closed for user root I don’t encounter this behaviour when connecting to other virtual machines, so I guess the problem isn’t in the network. Any help is appreciated.

• WLC 4400. Get IP

  - by Edward Connelly

  I have three SSID. one is a guest network and I'm having problems with lease times. Its set for web authentication so it passes IPs out even if someone doesn't try and authenticate. Is there a way to get that IP back and not hand another to that mac for a period of time? Poor planning and we didn't allocate enough address space, and we are sandwitched. We could go with another address, but we would have to reconfig lots. since its guest its vlan'd with no access to anthing but the firewalls. would have to change ACLs and routes and interfaces. if it isn't possible we will just have to go that route, just thought there might be an easier solution. session timeout is enabled with 1 hr lease time is set to 4 hrs. no helper DHCP and internal DHCP is set with the space split across three WLCs (60 waps split across those as well).

• DNS point to server on ISP and keep shared host too?

  - by Dwayne

  I know this is probably quite easy to do, but I might just have the right search sorted out... so here is the situation: We have example.com set up as a hosted server along with app1.example.com, app2.example.com and a few others. What I would like to do is set up the right zone file to also make our internal server addressable from the outside world as internalapp.example.com. This server sits behind a firewall (pfsense) and is hooked up to the world via a cable modem that is technically on DHCP from our ISP, but has had the same external IP for the past 15 months so far. What would be the best way to set this up?

• Log with iptalbes which user is delivering email to port 25

  - by Maus

  Because we got blacklisted on CBL I set up the following firewall rules with iptables: #!/bin/bash iptables -A OUTPUT -d 127.0.0.1 -p tcp -m tcp --dport 25 -j ACCEPT iptables -A OUTPUT -p tcp -m tcp --dport 25 -m owner --gid-owner mail -j ACCEPT iptables -A OUTPUT -p tcp -m tcp --dport 25 -m owner --uid-owner root -j ACCEPT iptables -A OUTPUT -p tcp -m tcp --dport 25 -m owner --uid-owner Debian-exim -j ACCEPT iptables -A OUTPUT -p tcp -m limit --limit 15/minute -m tcp --dport 25 -j LOG --log-prefix "LOCAL_DROPPED_SPAM" iptables -A OUTPUT -p tcp -m tcp --dport 25 -j REJECT --reject-with icmp-port-unreachable I'm not able to connect to port 25 from localhost with another user than root or a mail group member - So it seems to work. Still some questions remain: How effective do you rate this rule-set to prevent spam coming from bad PHP-Scripts hosted on the server? Is there a way to block port 25 and 587 within the same statement? Is the usage of /usr/sbin/sendmail also limited or blocked by this rule-set? Is there a way to log the username of all other attempts which try to deliver stuff to port 25?

• SATA Devices not showing up when in UEFI mode

  - by Dan Barzilay

  I'm trying to install Windows and the bios should be set to UEFI mode. The problem is that all SATA devices aren't showing up (shows as if there aren't any) so I can't boot from the installation CD (it's just not there). The weird thing is that when set to LEGACY mode they all show up.. SATA mode is set to AHCI and I'm on Lenovo Y510P. I have a Linux OS installed that is accessible only when BIOS is in LEGACY mode (otherwise the hard drive it's on is not available) I also tried reseting the BIOS settings which didn't help.. Comment please if more details needed Extra details: Computer model: Lenovo IdeaPad Y510P (not overcloacked) Installed Linux OS version: Linux 3.7-trunk-amd64 x86_64 Trying to install Windows: Windows 7 Ultimate 64bit BIOS Information: Vendor: LENOVO Version: 74CN26WW(V1.07) Update: Using user1608638 answer and suggestion of using the USB flash drive as the boot device instead of the CD/DVD method I succeeded in installing Windows 7! (Thanks alot user1608638)

• Fresh Apache install can't be connected to

  - by Wayne M

  I've got to be missing something here. I have a brand new CentOS server with a LAMP install on it. My domain host (GoDaddy) has the server's IP address configured as the "A Record". Since the server will host subdomains I have enabled NameVirtualHost and set up a virtual host pointing to the web app on the server. I haven't touched anything else in Apache, and it's listening on Port 80 like it should be. However, I can't connect to the server either by DNS or by IP address. I've set up several servers exactly like this one and never run into this before. What could be causing this? Did someone on the host set up a firewall or something that blocks port 80? As I said, I can't connect to the server via anything, but it's a barebones box with LAMP installed on it.

• DNS problems : correct nameserver, namserver working, but not resolving

  - by user1719624

  My problem is as follows. Any suggestions are welcome. [domain].org is not resolving whois and checking the registry information shows that the correct nameserver is set. The primary nameserver is also the server on which domain.org is hosted. The primary nameserver is also used for a number of other domains, and is working fine for those. Logging into the server, I can ping [domain].org and it resolves correctly. Setting the nameserver as my own DNS server on my laptop, and the URL resolves correctly. If the domain has the correct nameserver set, and the nameserver can resolve the URL to the correct IP address, and if I use the nameserver as my DNS then it resolves correctly, AND the nameserver is used for other domains which are resolving correctly, then why isn't it working? NB : this is a new domain registration and has been set up for around 10 days now, so it's not simple slow propagation. Any ideas? thanks

• Is Apache ReverseProxy to Passenger Standalone an acceptable production deployment?

  - by davetron5000

  I have the need to deploy Rails 3 apps, using RVM and gemsets, and am expecting “public” traffic (i.e. this is not an internal-only app). I also must use Apache as the public interface to my app. I understand that Passenger Standalone can help accomplish the rails/RVM end, and I have successfully set it up in my development environment. My question is how viable this setup is for a production deployment. Is deploying via Apache configured to ReverseProxy to my passenger-powered Rails app going to create problems? Since I'm designing the production deployment now, I want to understand if I should spend the additional time to set up Passenger connected to Apache and have that Passenger communicate with Passenger Standalone instance running my Rails app. So, I'm looking for one of I guess three answers: Apache Reverse Proxy to Passenger Standalone will be generally fine You should not use the Apache/Passenger Standalone configuration, but set up Passenger on the Apache side as well Your entire setup is just Wrong, please RTFM (and include link to "FM")

• How do I add an Approver to SharePoint 2010?

  - by CompGeekess

  I am still new to SharePoint and am learning so much, but have came in to a few hic-ups and here is one. I want to add an approver to SharePoint 2010 who has FULL CONTROL. My manager requested that I find out where the approval request are going and redirect them to him. (I have no idea where or how to find this out). Is this possible to do on the Central Administration or must I go into each site/subsite and set him to be the approver this way? Googled and the site was showing me how to approve workflows or how to create approvals, my other resources didn't give much help either. So far I had gone into a few individual sites and set my manager and I up as approvers with full control, but am uncertain if this is the correct procedure or if there is a better way to do this. For example, have the lower levels inherit from the higher level - set security at the highest level and cascade to the child levels. Thank You.

• X11 not sending windows to remote computer matlab

  - by MZimmerman6

  I am trying to set up my home desktop, running OS X Mountain Lion, to basically do a bunch of grunt work for me remotely. I have set up ssh, and am able to remotely control the computer fine, but the issue comes in when I try to run X11 apps, like MATLAB, remotely and get windows to pop up. Every time I try to bring up a new window it either opens that window on the remote computer (not the one I am using to control it), or it tells me it can't find a display. here is how I am setting up my ssh assume my matlab alias is set up properly, which it is. ssh -X [email protected] matlab -nodesktop figure; This will open the window on the computer I am SSHing into, and not on the remote one. Basically I want that window to open on the computer I am remoting from. I changed my SSH X11Forwarding and stuff to be yes in ssh_config and sshd_config. Any other suggestions?

• TB3.0.10: Messages being sent back to me

  - by punkinette64

  Hello, I don't know if this will make any sense to you; but here goes. When I send an email and I get a response, more often than not, in the 'to:' is my email address. However, my email address also ends up in the 'from' column.The 'reply-from' address is nowhere to be found;so I don't have any address with which I can send my reply, as both of them have just my email address. What am I doing wrong here? Is there some set-up in my TOOLOPTIONS set-up incorrectly? The set-up in OPTIONS is pretty difficult to understand and it doesn't offer any 'to' or 'reply-from' choices. This is critical because I just cannot answer my emails because there is no one I can send a reply to. Please, please try to help me. If you have the answer, please email me at: [email protected] Thank you. Blessings. Shiloh

• Migrating users and IIS settings from a workgroup win2k3 machine to a new win2k8r2

  - by amber

  I am retiring my old Windows Server 2003 Standard 32bit machine to a new machine with Windows Server 2008 R2 Standard. The two sticking points are migrating user accounts (and there are a lot of them) and IIS settings/websites (again, there are a lot). The new machine has not been provisioned yet. I'm at that point where I'm about install the OS on it. The old machibe is configured with a mirrored set for its OS and data partitions. I have broken the mirror set, replicated all of the data to an external drive, and then rebuilt the mirror set. In short, I have an image of the old machine to play with while safely leaving it up and running. Thanks!

• One subdomain is not working

  - by BFTrick

  Hello there, My main domain works just fine - www.example.com and a subdomain set up by another developer works as well - sub1.example.com. But when I try to set another subdomain up I go through the process everything seems to work. The software creates the default files where the subdomain files should go. But when I try to browse there it doesn't work. My host uses Plesk to do all of the hosting stuff. What do you think the problem is? I doubt it is some sort of cache issue because I had problems on my phone which I tried after problems on the pc. Maybe for some reason Plesk needs time to set this up? I have used Cpanel before and that works instantly.

• Is 10% too much for autogrow on a 4 GB sql server DB?

  - by ntsue

  I am getting the following error: 2011-03-07 21:59:35.73 spid64 Autogrow of file 'MYDB_DATA' in database 'MYDB' was cancelled by user or timed out after 16078 milliseconds. Use ALTER DATABASE to set a smaller FILEGROWTH value for this file or to explicitly set a new file size. I did some research, and I found that for large databases you should set autogrow to a fixed size (MB), and not to a percentage. I feel like this database is not large and I may not be addressing the correct issue by changing this value. Does anyone have any opinions? Thank you! EDIT: I should have specified SQL Server 2008 RC2 running on Windows Server 2008

• Setting up linux server with multiple access rights

  - by Mark

  I am a graduate student and want to set up a linux server (preferably Ubuntu) in my office. I also want to give my friends SSH access to that box. My question is can I set up my server such that I can give one of my friends rights to install software on my machine but he cannot brows around outside the directory he is allowed to? Can I set up multiple apache instances (on different ports) for different people? so each has access to their own apache instance?

• Group Policy for Setting Passwords: Server 2003 Domain

  - by user1236435

  In my 2003 domain, I am being requested to set a password policy to require passwords to expire every 4 months, and also require users to change their password on their next login, due to a security issue. In my domain, my OU's are setup by location, then drilled down to city, then the users and computers are in separate sub-domains. My question is, how do I set this up for my domain? Will I need to set the policy up for loop back? Can I configure this for just a specific OU? Any suggestions on how to move forward? Any advise is much appreciated, and thanks in advance!

• FTP Folder Permissions / IIS8

  - by raam030

  I am having trouble copying information from one folder on an FTP site to another folder. Accessing the FTP site from a windows explorer. I have set Full Control over the parent folder, and I double checked...I have full control over the two folders that is trying to copy information from and to. It actually lets you right click and copy. Then when you try to go to another folder and right-click and paste, the paste option is grayed out. I was able to do it before and no one has changed the IIS permissions. I believe it's a Windows issue. Is it possible that even though the permissions are set to give full control over that directory, that something else is interfering? I did double check the IIS permissions. I am not on a domain, using anonymous access, made sure the access control is set to read/write.

• asterisk outbound caller id

  I'm trying to set the caller id number for an outbound call. My asterisk .call file looks like this: Channel: SIP/flowroute/1234567890 Context: test Extension: 1234567890 Priority: 1 Here's my extensions.conf: [test] exten => _1NXXXXXXXXX,1,Set(CALLERID(num)=8005552222) exten => _1NXXXXXXXXX,n,Dial(SIP/${EXTEN}@flowroute) exten => _1NXXXXXXXXX,n,Playback(hello-world) When I receive the call, the caller id number is 1-206-445-6979, even though the CDR log has both src and clid set to 8005552222. I'm using flowroute as my carrier. Is there something wrong on their side?

• How do I start a cloud9 service

  - by Lord Loh.

  Cloud9 is a free IDE available from https://github.com/ajaxorg/cloud9/ under GPLv3. I would like to use this to set up a service like https://c9.io/. The Cloud9 documentations do not mention anything about it. The Cloud9 documentation assume a sing user on localhost or bind to another address without one hard set username and hard set password. How do I run cloud9 IDE on my computer allowing multiple users? Are there any documentations? This is the closest to what I found - https://github.com/avgp/cloud9hub (for multiple workspaces)

• Why are Rules not applied to additional mailboxes when using Outlook 2007 and Exchange?

  - by Clean

  Hi, I've set up a few rules in Microsoft Outlook 2007. Outlook 2007 is configured to use my Microsoft Exchange account. In the Microsoft Exchange settings, I've set up two additional mailboxes, Inbox1 and Inbox2. Thus, using Microsoft Exchange I now have three mailboxes: Inbox, Inbox1 and Inbox2. The rules I've set up all work fine for mails arriving in the Inbox. However, they do not work at all for mails arriving in either Inbox1 or Inbox2. Do anyone perhaps know why this is, and perhaps what I could to to solve this? Thanx in advance!

• When to run SYSPREP

  - by haxel

  I am attempting to set up a computer using an answer file created by the WAIK and resetting the settings with SYSPREP and had a quick question. We are wanting to use Norton GHOST for our deployments. When do I run the sysprep? I figure it is after I get the computer all set up with the proper updates/software/drivers but I have not been able to find a direct answer to this online. Do i run it after everything is set up and the system is ready to be captured?

• Windows services not starting automatically?

  - by Jeff Atwood

  We've had some nasty time sync problems on our Windows Server 2008 R2 servers lately. I traced this back to something very simple: the Windows Time Service was not started! The time can't possibly sync via NTP when the time service isn't running... The Windows Time Service was set to start "automatically" in the services control panel, which I double and triple checked. I also checked the event logs and I didn't see any service failures or anything like that. In fact, it looked a heck of a lot like the Windows Time Service never started up automatically after the weekly Windows Updates were installed and the servers were rebooted. (this is set to happen every Saturday at 7 PM.) The minute I started the Time Service, the time synced fine. So, then, the question: why would a service set to start "Automatically" ... not be started automatically? That seems sort of crazy to me.

• wmp12 refuses to convert files when syncing

  - by Carbonara

  I have quite a large music collection of MP3s at 320kbps and some WMA files at various bitrates. I'm trying to sync some of them to my HTC Desire and am quickly running out of space. WMP12 has options to set, per device you wish to sync, to auto convert to a lower bitrate whilst syncing. I have set this to auto convert files to a maximum bitrate of 192kbps, that way I can fit more music on the device but keep the files on my PC at the higher rate. See these screens to see that it's set up correctly. Only problem is, surprise surprise for a Microsoft product, it doesn't actually work. Any file that is greater than 192kbps, MP3 or WMA simply fails, doesn't get converted or copied to the device. The message in the sync log displays the rather unhelpful message "error" and that's it. Any help would be appreciated. I'm not really looking for alternative software solutions I'd like to get this working since that's what it's supposed to do.

• Zentyal Server : Setting up secure VPN Client

  - by JustShrey

  I have officially exhausted pretty much all my google-fu trying to set this up so I'm asking my question here. For the record, I am a mid level rookie who has played around with servers in his spare time but have never worked with Zentyal Server. Now, I have been able to set up the server as a gateway, with one Network card being external and the other facing the internal Network. The Internal network computers are able to access the internet without any issues. What I need to do is to setup a open-vpn client on the central server so that all Internet data goes though the secure VPN session. As far as I can see, I can't set up the vpn session through the web admin page. Could somebody point me in the right direction? How would I go about doing this? Regards Shreyas
