• Require TLS on RDP for all connections

  - by MarkM

  I have a 2008 DC and a 2008 AD CS server and a Windows 7 client. What I would like is to require the certificate to be used when RDPing to the server. The certificate is valid, and if I connect using the FQDN I am shown that i was authenticated by both the certificate and Kerberos as expected. When I connect with just the hostname I am allowed to connect and am only authenticated by Kerberos, even though I have Require TLS 1.0 set on the server that I am RDPing to. I fully understand that the certificate will not be valid unless the server is accessed by FQDN, what I want to do is disallow connections that do not use the certificate AND Kerberos. I thought that setting Require TLS 1.0 would do it. What am I missing?

• LVS TCP connection timeouts - lingering connections

  - by Jon Topper

  I'm using keepalived to load-balance connections between a number of TCP servers. I don't expect it matters, but the service in this case is rabbitmq. I'm using NAT type balancing with weighted round-robin. A client connects to the server thus: [client]-----------[lvs]------------[real server] a b If a client connects to the LVS and remains idle, sending nothing on the socket, this eventually times out, according to timeouts set using ipvsadm --set. At this point, the connection marked 'a' above correctly disappears from the output of netstat -anp on the client, and from the output of ipvsadm -L -n -c on the lvs box. Connection 'b', however, remains ESTABLISHED according to netstat -anp on the real server box. Why is this? Can I force lvs to properly reset the connection to the real server?

• Firewall software that can block access to certain applications on certain internet connections

  - by webmasters

  I have two internet connections, a LAN and a 3G modem on a Windows 7 machine. The LAN is connected to a Edimax router which is conneted to the ISP (with their own modem). Now, the Edimax router is set to auto assign IP adresses in the range: 168.192.2.100 and 192.168.2.200 I wanted to block internet explorer to access the LAN. I entered my AVG firewall, selected iexplorer and added a "block" rule which blocked all ports, TCP and UDP protocols for the above IP range. The problem is it did not work, not matter what rules I have tried. Can you recommend a firewall that can easily accomplish this? Ty

• How do I bridge connections in windows 7?

  - by Wolfgang Haak

  At work, our ISP has gone down, 3 days running. A company next door has kindly provided us with access to their wireless network, and I'd like to get our internal mail server (win 7) to become online via that wireless connection, while being accessible from within the LAN, but I'm struggling with the windows configuration. Our company's LAN subnet (wired interface) sits on 192.168.0. Neighbour's wireless subnet 192.168.1. I've tried bridging the connections but that disconnects the mail server from the Internet connection and the LAN. what do I have to do achieve this networking configuration? Kind regards, Wolfgang

• ssh port forwarding freezes after 10 simultaneous connections

  - by Marko Kevac

  Hello. I am using port forwarding to utilize proxy server which is on remote machine. Remote machine hostname is remotemachine. Proxy is listening on 8118 port. I am translating this port to local port 5223. ssh -vvv -N remotemachine -L 5223:localhost:8118 Everything is fine if I don't use more than 10 simultaneous connections, when ssh just freezes. It no longer send data trough port forwarding. I.e. ab -c 10 -t 5 -X 'localhost:5223' 'http://www.google.ru/' works, but ab -c 20 -t 5 -X 'localhost:5223' 'http://www.google.ru/' causes ssh to freeze MaxSessions 30 parameter in /etc/ssh/sshd_config didn't helped at all. What can I do to remove this 10 connection limit? Nothing interesting in -vvv output =(

• Using multiple wifi connections simultaneously on Windows

  - by Salman A

  My office PC has a one wireless network card and there are three available wifi connections: primary, backup and backup of a backup (grin). Is it possible for me to use all three simultaneously. If this results in an increase in bandwidth that's well and good, but primary reason is every now and then one of the network fails and i have to switch back and forth between the available networks by disconnecting, viewing available networks and connecting to next one hoping its running. Do i need more than one network card or a software e.g. a proxy.

• Dovecot ignoring maximum number of IMAP connections

  - by Michelle

  I have a single mailbox mail server running Dovecot/Postfix and I have two IMAP clients, Thunderbird on the PC and K9 on Android. I keep on receiving this error in my logs even after I change the 'mail_max_userip_connections' variable to 50. puppet dovecot: imap-login: Maximum number of connections from user+IP exceeded (mail_max_userip_connections=10): user=<[email protected]>, method=PLAIN, rip=62.242.90.2, lip=198.29.31.229, TLS Why does it say that it is set to 10 in the log? Is that hardcoded? grep -r "mail_max_userip_connections" /etc/dovecot /etc/dovecot/conf.d/20-managesieve.conf: #mail_max_userip_connections = 10 /etc/dovecot/conf.d/20-pop3.conf: #mail_max_userip_connections = 3 /etc/dovecot/conf.d/20-imap.conf: mail_max_userip_connections = 50 I've restarted dovecot after making the changes but this error is still logged and I can't access the mailbox. Can anyone help me understand why I can't seem to raise the maximum limit?

• What ports do I need open for IMAP connections

  - by iamjonesy

  I'm developing a web application that connects to an IMAP mailbox and fetches emails as part of it's functionality. The application is PHP and I'm connecting like this: public function connect() { /* connect to gmail */ $hostname = '{imap.gmail.com:993/imap/ssl}INBOX'; $username = $this->username; $password = $this->password; /* try to connect */ $this->inbox = imap_open($hostname,$username,$password) or die('Cannot connect to Gmail: ' . imap_last_error()); } Developing locally on my mac this was fine, I was able to connect and get emails. However now that I've put the app on my web hosts server I'm getting the following error: Cannot connect to Gmail: Can't connect to gmail-imap.l.google.com,993: Connection timed out After checking with my hosting provider they told me outgoing connections on port 993 are blocked. Is there anyway around this? Otherwise I need to upgrade to a dedicated server :S

• How to configure Windows 2008 R2 server for LAN and wireless internet connections

  - by Alchemical

  For special testing purposes, we need a Windows server to allow the following: A team member can log in remotely to the server. When remotely logged in, they can disconnect the wireless connection, perform a few tests, and then reconnect the wireless connection. In general, the LAN connection would just be used for the remote login, the wireless connection would be used for performing tests including using a web browser to test certain web sites, etc. How can we successfully configure the server to support 2 network connections like this? (A regular LAN connection + a wireless connection). And also make sure that the tests we perform using the browser utilize the wireless connection for the outgoing internet activity.

• LAN speeds and firewall/switch connections

  - by microchasm

  I have a small network with about ten users. All workstations flow into a Dell PowerConnect 3424 which then has a single link to a SonicWALL firewall and from there to a cable modem. More important than internet connectivity is speed between machines (specifically a Windows Server box on the LAN which everyone uses simultaneously). I believe the 3424 has gigabit connections, but they look like they're for stacking. Is there a way to test the speeds on the LAN to see where the speeds are at? Is there any low-hanging fruit insofar as increasing speeds?

• Virus blocking incoming connections ?

  - by Benoît

  Hello, on my windows 2003 server, all incoming connections are dropped. I can see them getting in using Wireshark, but even a single ping from another computer fails. All locally initiated connection work fine (i'm asking from the server). This server is the DC/DHCP/DNS/File server, so computer clients are in the dark. I've run varius antivirus and removal tools without any luck. The Windows Firewall is disabled. I'm wild-guessing at some virus/worm. How can i check why these incoming ICMP/TCP SYN/etc are dropped ? Anyone has any knowledge about such situations ? Thanks.

• MySQL too many connections

  - by Webnet

  On my server I have 7 databases. Our server has 512 MB of RAM which I'm getting upgraded this evening to 2GB and has a 2.4 single processor. I've gotten an error about the connection limit exceeded. With increasing my RAM, is it ok to increase the number of connections? Currently it's set to 200 but a single page may connect to 3-4 databases considering JOINs and things. We've setup so many databases for mere organization. We have a total of about 250-300 tables in all of the databases. Any advice would be appreciated :)

• Google Chrome suspicious connections

  - by Poni

  I'm using Chrome at Windows and with TCPView (of the SysInternals freeware suit) I see that chrome.exe establish connections to these IPs: 173.194.37.104 209.85.146.138 Using http://www.ipaddresslocation.org/ I check about these IPs and see they're related to Google. Now, in order to clarify, these are the exact things I do: Open up chrome, the default page is set to BLANK (i.e no homepage whatsoever). Then I get into my website which has a blank page, so no "other" http requests are made. Right from this point there is a persistent connection, usually to '173.194.37.104'. What are these?? Very suspicious.. Edit #1: - I'm in 'incognito' mode right from start, when launching Chrome, using a shortcut with the '-incognito' switch. - I've turned off all phishing protections and other "advance" features in order to reduce Chrome's network activity.

• Two VPN (internet) connections rounting (win2003)

  - by tmp3128

  Here is my setup: - win2003 server (ISA installed) with 3 NICs:   1) internal network   2) ISP 1 (default) network (DHCP enabled)   3) ISP 2 (backup) network (DHCP enabled) - several "normal" PC within internal net - one "special" PC within internal net Both ISP 1 and ISP 2 provide access to internet and their resources thru their VPN connections. The goal is to enable all "normal" PCs to use internet from ISP_1's VPN connection and "special" should use only ISP_2's VPN connection. Futhermore all "normal" and "special" PCs should have access to several servers accesible only thru ISP_2's VPN connection. I have some thoughts how to achieve this but I want to be certain because everything should be configured as quickly as posible, avoiding significant downtime. windows-server-2003 isa routing vpn

• Limit maximum incoming connections to a port using iptables

  - by Harley

  I have a server that has apache listening on a number of ports. Some ports are used for configuring the server, and another is used to download large files. My problem is that when I have a large number of clients downloading files, the web interface is uncontactable. I would like to limit the number of clients connecting on the "large file" port so that apache always has available connections to configure the server. A REJECT is fine, the client trying to download the file will back off and retry later. Each client only has one connection open to the server at a time, so limiting by IP won't work. I know I could put something in front of apache to manage this, but I'd really like to do it in iptables, without adding more software.

• Set nginx.conf to deny all connections except to certain files or directories

  - by Ben

  I am trying to set up Nginx so that all connections to my numeric ip are denied, with the exception of a few arbitrary directories and files. So if someone goes to my IP, they are allowed to access the index.php file, and the phpmyadmin directory for example, but should they try to access any other directories, they will be denied. This is my server block from nginx.conf: server { listen 80; server_name localhost; location / { root html; index index.html index.htm index.php; } location ~ \.php$ { root html; fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /srv/http/nginx/$fastcgi_script_name; include fastcgi_params; } } How would I proceed? Thanks very much!

• Barring connections if VPN is down.

  - by Majid

  I have a VPN account and use it for sensitive communication. However the VPN connection sometimes is dropped while my main connection to the internet is still alive. The pages I visit through VPN are on HTTP (not secure) and have javascript code which pings the host every minute or so on a timer. So it happens sometimes that the VPN connection is dropped and yet js sends a request to the server (with the cookies). How could I restrict connections so they only happen if the VPN is live? Edit - Some required details were missing OS: Windows XP SP2 Browser (mostly used): Google Chrome Firewall: Windows default Sites to filter: not all traffic but all in a list of sites like abc.com, xyz.com

• RDP connections keep dropping

  - by Shaul

  I have an odd problem on my notebook (HP Pavilion dv7). My Internet connection seems OK for the most part. But lately I've been having trouble with Remote Desktop connections. While I can connect to remote computers, the connection is very flaky, and usually drops after a few seconds. Sometimes it'll successfully reconnect automatically, and sometimes not. But even after successful reconnection, it'll just drop again after a few seconds. This appears to be independent of which RDP host I'm connecting to, and which network I'm connected to locally, whether wireless or wired. Other remote control apps like TeamViewer and Ammyy seem to work fine. Any ideas?

• Tomcat's connection pool opens only 20 connections to mysql

  - by stck

  I have a java application with following line in context.xml <Resource driverClassName="com.mysql.jdbc.Driver" maxActive="100" maxIdle="30" initialSize="10" maxWait="7000" name="jdbc/app" password="pass" type="javax.sql.DataSource" url="jdbc:mysql://dbhost:3306/dbname?autoReconnect=true" username="user" validationQuery="SELECT 1" removeAbandoned="true" removeAbandonedTimeout="30" logAbandoned="true" /> In mysql 'show variables' tells me that max_connections is 151. Still, use information_schema; select count(*) from processlist where User = 'user'; never shows me more than 20 connections. On tomcat's catalina.out -log I get Caused by: org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot get a connection, pool exhausted at org.apache.tomcat.dbcp.dbcp.PoolingDataSource.getConnection(PoolingDataSource.java:103) at org.apache.tomcat.dbcp.dbcp.BasicDataSource.getConnection(BasicDataSource.java:540) at org.springframework.jdbc.datasource.DataSourceUtils.doGetConnection(DataSourceUtils.java:113) at org.springframework.jdbc.datasource.DataSourceUtils.getConnection(DataSourceUtils.java:79) What should I check for to find the problem?

• Remove Windows 7's limitation on number of concurrent tcp connections (http web requests)

  - by Ghita

  I have an application that tries to open as many http requests as possible (in order to stress test a proxy implementation) It seems to me that Win7 (SP1) may have a limitation on number of concurrent opened connection (it may be the so called half-open state if I'm not wrong). Is there something I can do for client ? and also I test using a vista PC that acts as a proxy server. It would be great if I could configure it to sustain at least 50 new connections initiated / second on client side and many more on server. I made the modification according to this technet article by setting TcpNumConnections = 150 but it doesn't make a difference. I still only see about 20 tcp sockets associated with my http client by using tcpview.

• Windows 2003 Server Suddenly Drops Connections to everything but PING and port 80 (webserver)

  - by Urda

  Hi, I'm running a Windows 2003 Dedicated server, and the box has been rock solid for more than 2 years now. Just recently, I have had an issue where after a certain ammount of time the server will just stop accepting connections on all ports except 80, and still responds to pings. If you surf to a static HTML page on the box, you can display it. If you pull up a PHP file that has an outside database connection, it fails. RDP refuses to connect, and LogMeIn reports that "The connection was reset" The only fix at this time is to have the provider physically reboot my box to correct the issue. The event log doesn't seem to be leaving helpful messages, and I am at a lost to what is causing this error since I have not installed any new software in months on it. Any tips or help would be appreciated to tracking down this issue. I don't mind updating the question as responses come in, I just do not know where to start troubleshooting because it seems random at this time.

• Iptables - Open Port Only for one Server IP (allow connections from a specific range)

  - by user1015314

  My server has multiple IPs, 1.1.1.1 1.1.1.2 and i have a service which listens to a port e.g. 88 Now i want, when somebody from outside, wants to connect to the port, that he can only connect, to that port, if he connects to the ip 1.1.1.2:88 but if he tries to connect to 1.1.1.1:88 it should not react and it should look like that it dont exists and drops all connections. Ok, than i need for 1.1.1.2:88 that only allows a specific ip range outside connecters. for example only 9.*.*.* can connect to that port and ip. I'm using Centos. Thank you for your help.

• Two VPN connections from the same IP address

  - by Tayles

  I have set up a server running Windows Server 2008 which two remote users can dial into using a VPN connection. It works fine unless they are both in the same location, in which case only one of them can connect. I understand this is because the PPTP protocol cannot cope with two VPN connections from the same IP address. Is this correct? If so, what can I do about it? Please note that the remote location in question is a serviced office, so we're not in a position to change or play around with their router. Thanks!
