• PuTTY/SSH: How to Prevent Auto-Logout?

  - by feklee

  My ISP's SSH server (Debian 2.0) logs me out after 35 minutes of inactivity, when connected with PuTTY (Windows XP). This is a big problem when I utilize the server for port-forwarding. The final messages displayed in the terminal: This terminal has been idle 30 minutes. If it remains idle for 5 more minutes it will be logged out by the system. Logged out by the system. PuTTY options that do not help: Sending of null packets to keep session active. Seconds between keepalives (0 to turn off): 30 [x] Enable TCP keepalives (SO_KEEPALIVE option) Any idea how to avoid the auto-log-out? Should I try another SSH client?

• How to set up memcached to use unix socket?

  - by alfish

  While I could use memcached on Debian to use the default 11211 port, but I've had great difficulty setting up unix socket, Form what I'v read, I know that I need to create a memcache.socket and add -s /path/to/memcache.socket -a 0766 To /etc/memcached.conf and comment out the default connection port and IP, i.e. -p 11211 -l 127.0.0.1 However, when I restart memcached I get internal server errors on Drupal site. I'm trying to implement unix sockets to avoid TCP/IP overhead and boost overal memcached performance, however not sure how much performance gain one can expect of this tweak. I appreciate your hints or possibly configs to to resolve this.

• How do I access an Ubuntu VirtualBox guest at a static IP from an OS X host?

  - by David Siegel

  How does one configure an Ubuntu guest to use a static IP that's visible to an OS X host, and ensure that the static IP is independent of the host's network configuration? I previously used bridged networking for my guest, but I'm constantly moving my host between networks so the guest IP is always different. First, I tried setting the guest network configuration to NAT and forwarding host port 1022 to guest port 22, so I could at least ssh to a fixed address (localhost:1022): $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/Protocol" "TCP" $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/GuestPort" 22 $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/HostPort" 1022 Then, $ ssh localhost -p 1022 ssh: connect to host localhost port 1022: Connection refused But this didn't work (guest has no network access with NAT and OS X refused the connection, as you can see). I'd love a general solution that would let me communicate with my guest at a fixed IP.

• Torrent, ISA Server 2006 and packet dropped due to TCP_NOT_SYNC

  - by Pascal

  Hi, I'm trying to get uTorrent 2.0.4 to work in a DMZ machine, protected by a ISA Server 2006. I've opened 1 inbound port (via publishing) and opened all the higher ports for that specific machine that runs uTorrent on my DMZ, and it's working almost fine. The problem is that I keep getting packets dropped with 0xc0040017 FWX_E_TCP_NOT_SYN_PACKET_DROPPED. Is there any way to disable this via registry? Is there any way around this? The download speed fluctuates a lot, and when I starts hitting the upper limit that I've defined in uTorrent, the errors start poping up a lot, and the download speed goes way down, and the process repeats on and on Tks Edit My outbound rules are: Port Range: TCP 10000-65535 Outbound Port Range: UDP 10000-65535 Send Edit It's probably a bug handling requests from Windows 7. When I installed the uTorrent on a XP machine, the problem went away

• MySQL on Windows - how do I set the wait_timeout for connections using named pipes?

  - by gustafc

  I use a MySQL database running on a Windows box, and for performance reasons I'm connecting to it using named pipes. The (Java) application using the database (through Hibernate) can let the connection lie idle for quite a long time, which causes the connection to fail with the following message: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 33 558 297 milliseconds ago. The last packet sent successfully to the server was 33 558 297 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem. autoReconnect unfortunately has no effect (and neither does autoReconnectForPools), but the wait_timeout docs state that wait_timeout only applies "to TCP/IP and Unix socket file connections, not to connections made via named pipes, or shared memory". How can I change the wait_timeout for named pipes?

• High availability for Windows Service under Windows Server 2003

  - by empi

  Hi. I have a following situation: I need to deploy a windows service that listens for incoming request on tcp port (basically WCF service). I have a High Availability requirement - the service must be deployed on two servers and if the service stops (only the service, not the whole server) on one server, all the requests must be redirected to the second one. For me it looks like a basic failover scenario. How can I achieve this on Windows Server 2003? Should I use Microsoft Cluster Service or Network Load Balancing? The important part is that the process of swapping the servers should not concern the clients (the client must see only single address / single host or domain name). Thanks in advance for help.

• UFW: force traffic thru OpenVPN tunnel / do not leak any traffic

  - by hotzen

  I have VPN access using OpenVPN and try to create a safe machine that does not leak traffic over non-VPN interfaces. Using the firewall UFW I try to achieve the following: Allow Access from LAN to the machine's web-interface Otherwise only allow Traffic on tun0 (OpenVPN-Tunnel interface when established) Reject (or forward?) any traffic over other interfaces Currently I am using the following rules (sudo ufw status): To Action From -- ------ ---- 192.168.42.11 9999/tcp ALLOW Anywhere # allow web-interface Anywhere on tun0 ALLOW Anywhere # out only thru tun0 Anywhere ALLOW OUT Anywhere on tun0 # in only thru tun0 My problem is that the machine is initially not able to establish the OpenVPN-connection since only tun0 is allowed, which is not yet established (chicken-egg-problem) How do I allow creating the OpenVPN connection and from this point onward force every single packet to go thru the VPN-tunnel?

• Ubuntu and mysql server. Something isnt allowing me to connect

  - by acidzombie24

  I have a question about mysql settings http://serverfault.com/questions/94054/remote-connections-and-mysql-on-ubuntu/94088#94088 now i want to figure out why i cannot connect. I made sure bind-address was commented out. I can ping the server within the VM but i cannot ping it from within the VM using mysqladmin --protocol=tcp --host=self_ip ping. I also followed along and check if my ports were open and they look like they are. I setup samba on that VM and can access that with no problem as well. It looks like ubuntu does not have a firewall either (i figured this out before) so i am stumped why the server isnt allowing my connection. Apparently the config file works on another person side http://www.pastie.org/742545 I am using Ubuntu 6.06 LTS just because of 'support' reasons. So hopefully this will be 'easy'?

• webmin not working on port 10000

  - by Ali

  Hi, I posted a similar question yesterday but can't seem to find that post. I have installed webmin on my server which has SSL and its service is running but I am unable to open it in browser. I thought may be the port is blocked by server's firewall so I entered port 10000 (TCP - inbound) in APF but still no luck. When I use https://localhost:10000 on server to access webmin then it works fine but not remotely. Why is such a simple thing so hard to run? Thanks

• routing traffic between two network cards through firewall

  - by RubyFreak

  I'm trying to test a network device (firewall) using a Linux box, with two network cards, one interface connected to the WAN zone and another interface to LAN zone. The configuration is similar with that |ETH0| <-> | FW | <-> ETH1 So from both interfaces I'm able to ping the respective firewall interface. But i'm not able to fire something like: ping -I eth0 ip.from.eth1 and to get any answer. Is that possible or should the linux network namespace solution or user level tcp stacks (VMs are out of question)

• Can't add printer on Windows XP

  - by SuperFurryToad

  I've added a HP 4250 printer to about half a dozen Windows XP PCs in our office without any problems whatsoever, but for some reason I haven't been able to add it to one particular PC today. I go through the Add Printer wizard to add a local printer attached to the PC, enter the new port number as a Standard TCP/IP Port, install the driver. At the end of the wizard I get the following error message: Full error message: "windows cannot connect to the printer. either the printer name was typed incorrectly, or the specified printer has lost its connection to the server." This doesn't make any sense as I am able to ping the printer from the PC. The print spooler is running, and any firewall software on the local PC is switched off.

• 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.

• how to limit upload bandwidth per user in linux?

  - by Gihan Lasita

  Can anyone provide the tc command to limit upload bandwidth per user in Debian Lenny? I found that to mark packets per user with iptables I can use the following command iptables -t mangle -A OUTPUT -p tcp -m owner --uid-owner testuser -j MARK --set-mark 500 but I have no idea how to use tc update by running following commands, i managed to limit testuser upload bandwidth to 10Mbit iptables -t mangle -N HTB_OUT iptables -t mangle -I POSTROUTING -j HTB_OUT iptables -t mangle -A HTB_OUT -j MARK --set-mark 30 iptables -t mangle -A HTB_OUT -m owner --uid-owner testuser -j MARK --set-mark 10 tc qdisc replace dev eth0 root handle 1: htb default 30 tc class replace dev eth0 parent 1: classid 1:1 htb rate 10Mbit burst 5k tc class replace dev eth0 parent 1:1 classid 1:10 htb rate 10Mbit ceil 10Mbit tc qdisc replace dev eth0 parent 1:10 handle 10: sfq perturb 10 tc filter add dev eth0 parent 1:0 prio 0 protocol ip handle 10 fw flowid 1:10 now the problem is, i do not want to limit testuser's FTP bandwidth but by running above commands FTP speed also limited to 10Mbit.

• UDP Reverse Proxy

  - by user180195

  I have found a way to make reverse-proxy to an external IP. Here is how someone making a request will see it's request being passed: Clients sends request Request reaches the Datacenter one in some place That datacenter, acting as a reverse proxy will redirect the same exact request to another datacenter. The datacenter will then process the request Although, this only works with TCP/HTTP (Looking currently at HaProxy). I am hosting game servers at the other datacenter (where the proxy is not) that are using UDP protocol. Do you know how can I setup a reverse proxy using the UDP protocol.

  Hello, At my home network I had a transparent proxy. This is the rule that forward all 80 traffic to my squid3.1 server at DMZ DNAT loc:!10.0.0.126 dmz:172.16.0.198:3128 tcp 80 - !172.16.0.198 Ok, I need to add more ips to avoid transparent proxy. I tried loc:!10.0.0.134,!10.0.0.126...but didnt work (also similars like [ip0,ip1]. I tried to google the answer cant find it (sorry no matches, not searching the right keywords) also I tried to read the docs, but they are really long (and indexes dont help me). Thanks!

• Accessing Windows 7 Printer from Ubuntu Linux via LPR/LPD or Samba

  - by nitbuntu

  Hi, I'm having difficulty printing from my Linux (Ubuntu 10.04) based PC to a printer connected to a Windows 7 machine. I was trying to connect using Samba (version 3.5.6) but this always brings up an authentication screen which never accepts any password I use. So I read somewhere that an alternative is to access the Windows printer via LPR/LPD. I added an LPR/LPD printer in Windows 7, but even within Windows 7, I am not able to print as the print que monitor shows as 'printer busy'. The printer in question is an Epson Stylus DX7400 and works fine when using the standard USB ports....but doesn't when I use with the LPR/LPD ports. I even opened up the TCP/IP port 515 in my McAfee firewall without any success. Any help with this would be highly appreciated. Additionally, does anyone have any idea how I can get Samba working for me?

• iptables NAT configuration

  - by Sarp Kaya

  Hello I am experiencing some issues with my iptables. Here's what I want to do: A(eth0)--------(eth0)B(eth2)---------------(eth2)C Brackets are interface names A,B and C are hosts. Now I would like to forward port number 80 of host C so that It would be accessed via host A. host A is 192.168.1.254 host C is 192.168.3.2 I intentionally ACCEPTed all FILTER chain options as the default policy because I wanted to make sure that NAT is working properly first. I enabled ip_forward. So here's what I have done: sudo iptables -A PREROUTING -t nat -p tcp - d 192.168.1.254 -j DNAT --to 192.168.3.2 However it is not working. What am I missing here?

• Error while setting up Anywhere Access on Windows Server 2012 Essential (personalized domain name from Microsoft)

  I am trying to setup Anywhere Access on a Windows Server 2012 Essential Release Candidate, but keep getting this error: "The domain name was not setup for your server. Wait a few minutes and run the wizard again. An unknown error occurred. Please wait a few minutes and then try again". These are the options that I selected in the Wizard: I want to set up a new domain name Get a personalized domain name from Microsoft Entered my Windows live id and password xxxx.remotewebaccess.com And on the next page the error is displayed. I have setup my router (Linksys WRT160N) to forward all TCP traffic to the Server. UPnP is also enabled. If I hit my public (dynamic) IP (http://188.182.194.182/) I get the Windows Server 2012 homepage. Any ideas?

• Hardware/Software inventory open source projects

  - by Dick dastardly

  Dear Stackoverflowers I would like to develop a Network Inventory application that works on any operating system. Reports on every possible resource attacehd to a network. Reports all pertinent details of hardware and software. Thats (and i hate to use the phrase) my "End Game". However I am running before i can crawl here. I have no experience of this type of development, e.g. discovering a computers hardware and software settings. I've spent almost two weeks googling and come up short! :-(. So I am turning to you to ask these questions:- My first step is to find an existing open source project i can incorporate into my own code that extracts the fine grained details i am after, e.g. EVERYTHING there is to know about the hardaware and software on a single machine. Does this project exist? or do i have to develop that first? Have i got to write all this in C? I am guessing getting this information about a computer is going to be easier than for printers, scanners, routers etc... e.g. everything else you would find attached to a network. Once i have access to a single computers details i then need to investigate how i can traverse an entire newtork of printers, scanners, routers, load balancers, switches, firewalls, workstations, servers, storeage devices, laptops, monitors, the list goes on and on One problem i have is i dont have a 1000 machine newtork to play on! Is there any such resource available on theinternet? (is that a silly question?) Anywho, if you dont ask you wont find out! One aspect iam really looking forward to finding out how to travers the entire network, should i be using TCP/IP for this? Whats a good site, blog, usergorup, book for TCP/IP development? How do i go about getting through firewalls? How many questions can i ask in one go? :-) My previous question on this topic ended up with PYTHON being championed as the language/script to go with to develop this application in. Having looked at a few PYTHON examples they all seemed to be related to WINDOWS networks and interrogating Windows Management Instrumentation (WMI). I had the feeling you cant rely on whats in WMI, and even if you can that s no good for UNIX netwrks. Surely there exist common code for extracting hardware and software details from a computer? Why cant i find it on the internet? Pease help? Theres no prizes though :-( Thanks in advance I would like to appologise if i have broken forum rules or not tried hard enough on my own before asking for assistance. I just would like to start moving forward with this as its one of the best projects i have been involved with. I am inspired by the many differnt number of challenges involved and that if i manage to produce a useful application at the end of it it would hopefully be extremely helpful to many people. That sit Thanks in advance DD

• vPopmail / xinetd.

  I'm attempting to setup vpopmail on my CentOS server (Media Temple). Everything is working like a charm, with the exception that I cannot login to the server from any pop3 client. Upon trying to login I get the following error: Sending of password did not succeed. Mail server mail.(mydomain).com responded: Login failed. I'm running qmail (of course) with xinetd (not tcpserver). I've placed a file called pop3 into the folder /etc/xinetd.d with the content: service pop3 { disable = no socket_type = stream protocol = tcp wait = no user = root server = /var/qmail/bin/qmail-popup server_args = mail.(mydomain).com /home/vpopmail/bin/vchkpw /var/qmail/bin/qmail-pop3d Maildir log_type = FILE /var/log/xinetd.log log_on_success = HOST log_on_failure = HOST RECORD } Can anybody offer any guidance here? I've been unsuccessfully trying to make this happen for over a week.

• How to correctly set up iWARP? Preferably on loopback

  - by ajdecon

  iWARP is a protocol for doing remote direct memory access (RDMA) on top of TCP/IP, so that it can work with Ethernet and other network types as opposed to Infiniband. It works with many of the standard IB interfaces - the IB verbs, for example - so it's all pretty transparent. I'm doing some IB-verbs programming (mostly for the sake of learning about how they work better), and it'd be wonderfully convenient for me if I could use iWARP to do RDMA over my loopback interface, so that I could test some of my code without getting on our IB-connected cluster. :-) But I cannot figure out how to get a "local development environment" set up: there are no tutorials I'm aware of for even setting up iWARP from scratch on a server or a network interface. Can anyone give me a tutorial or point me in the right direction? Environment is Fedora 16 running in VirtualBox.
