• Forward all tracif from one IP to another Ip on OS X

  - by Josh

  This is related to this question I just asked... I have two IP address on my iMac I want to "bridge". I'm not sure what the proper terminology is... here's the situation. My iMac has a firewire connection to my laptop and an ethernet connection to the rest of my office. My laptop has an ip of 192.168.100.2 (on the firewire interface). My iMac has an IP of 192.168.100.1 on the firewire interface, and two IPs, 10.1.0.6 and 10.1.0.7, on it's ethernet interface. If I wanted to forward all traffic coming in from 192.168.100.2 on my OS X machine to go out on IP 10.1.0.7, and vice-versa, can this be done? I assume I would use the ipfw command. Essentially I want to "bridge" the firewire network to the ethernet network so my laptop can see all the machines on the 10.1 network, and all those machines can see my laptop at 10.1.0.7. Is this possible?

• SSH into Fedora 17 will not work with new users

  - by psion

  I just deployed a new Fedora 17 server on the Amazon EC2. I was able to log in as ec2-user with my generated keypair, but I cannot log in under normal circumstances as a user I created. This is just a normal ssh: ssh user@ip-address Any ideas on what is going on here? EDIT: This is a snippit from my sshd_config file # To disable tunneled clear text passwords, change to no here!

• Nokia 5800 v50, getting "Invalid server name" with ad-hoc wlan with Windows 7

  - by Krunal

  After upgrading to v50 firmware in my Nokia 5800 xpress music phone. I am not able to connect to ad-hoc wlan network in my laptop(Windows 7 OS). I have a dialup internet connection and created wireless ad-hoc network to access the internet in my phone. But I am getting "invalid server name" in the phone and my wireless network access type in Windows 7 shows "no internet access". I am able to connect to wlan infrastructure network using 5800 in my office. So my phone is working with wlan and I m able to access internet on it. BUT The problem is "dial up with ICS enabled" and "AD-HOC wlan network" in Windows 7. Can anyone give some solution on it. Or can you provide a guide/tutorial to connect 5800 with adhoc network and dialup internet in Windows 7. System: Windows 7 Dial up internet connection with ICS enabled. Ad-Hoc wireless network with WEP Nokia 5800 Xpress Music phone Note: I have read other posts also and tried their solutions but didn't worked for me. the first solution is to bridge the network and access it. but how can I bridge the dialup and wlan netwok? second solution is manually configure IP and DNS addresses in phone. But what should I add as IP and DNS as my dial up and adhoc network have automatic addresses.

• 1000Base-X layer 2/MAC address details

  - by user69971

  A layer 2 Ethernet frame is sent with a source and destination MAC address. Given a 100Base-TX (copper) trunk between two Cisco switches, I can do a "show interface fa 0/0" on S1 to see the MAC address assigned to the trunking interface, then go to Switch2 and do a "show mac address-table" and find the MAC address of the S1 fa 0/0 interface as a dynamically learned MAC in the table. Given a similar setup with a 1000Base-X (fiber GBIC) trunk, the MAC address shown in "show interface gi 0/0" on S1 does not show up in the MAC address-table of S2. Everything I can find online indicates that 1000Base-X uses largely the same layer 2 format as copper connections. There's some slight alterations - minimum frame size is slightly larger - but the fundamentals of the frame structure appear to be the same, including transmission with a source and destination L2 address. Why doesn't the address of gi 0/0 show up in the MAC address table of the connection switch? The only thing which seems to make sense would be that the GBIC has its own MAC address, almost as if its acting as a mini 2-port switch or hub, with the switch-assigned MAC address showing up on the interface connection and a different MAC address assigned to the fiber side. If this is the case, is there any way to see the GBIC MAC address on the switch? (I've tried to look up the details in IEEE 802.3z but it doesn't seem to be available without an IEEE membership or purchasing the standard. I find the base 802.3 PDFs for download, but not 802.3z.)

• INFORMIX - listener thread err 25582

  - by Samuel Lao

  I´ve been digging different forums in the last 7 days looking for a possible solution.... Our database is based on informix running in a Linux server (LINUX SUSE 11). Suddenly, last saturday informix began to show an error message: listener-thread err=-25582 oserr=0, network connection is broken End users started to call reporting about slow network performance to this server, moments where the database application lost connection with server...so we proceeded doing a ping to the db server, getting good responses (1ms) without losing packets. I tried typing telnet (ipserver) 1526 which is informix's port for the application, it works. We had to disconnect the server and enable a backup db server which is located on another branch. It has been working in a regular way because the backup server hasn´t good specs (it is an old dell server model). So, I scanned the main server looking for viruses using Trend Micro Server Protect, it didn´t find anything (0 viruses and spywares). I revised the switches and routers, but I haven´t find anything strange... What else could be ? Thanks in advanced for your time and help with this issue.....I would really appreciate any advice...

• Understanding what needs to be in place for a server to send outgoing email from a linux box

  - by Matt

  I am attempting to configure an openSuse 11.1 box to send outgoing email for a domain that the same server is hosting. I don't understand enough about smtp servers and the like to know what needs to be in place and working. The system already had Postfix installed, and I confirmed it was running via a > sudo /etc/init.d/postfix status I examined the Postfix config file in /etc/main.cf and configured a couple of items regarding the domain/host name and such, but left it largely default. I attempted to send an email from the command line with the following command: > echo "test 123" | mail -s "test subject" [email protected] Where differentdomain.com was not the same domain as the one best hosted on the server. However, the email never reaches the target account. Any suggestions? EDIT: In the postfix log, (/var/log/mail.info, there's nothing in .err) I see that postfix is trying to connect to what appears to be a different smtp server on our network, with a connection refused: connect to ourdomain.com.inbound15.mxlogic.net[our ip address]:25: Connection refused However, I can't figure out why it is 1) trying to connect to that server and 2) not just sending the messages itself... I mean, isn't postfix an smtp server? I did a grep -ri on ourdomain from /etc and see no configuration files anywhere telling it to do this. Why is it?

• Tool to sync bookmarks between devices in the local network

  - by Daps0l

  I'm looking for a tool to sync my bookmarks locally, without uploading them to any website (like xmarks does.) Example: i currently use 1Password to sync my logins/passwords. They are not uploaded to any website. The program simply syncs between devices (Mac OSX, iPad, Windows) on the local network, without the need of any remote server/database. Now i'm looking for a tool that does (kind of) the same thing, for bookmarks.

• Default route not on LAN

  - by jarmund

  I have a network that in principle looks like this: H1---\ /----Inet1 H2---->---GW1---< H3---/ \----GW2-----Inet2 H1 and H2 = Hosts that need access to internet with GW1 Inet1 = Internet link over 3G connection Inet2 = 5GHz link to Internet (not always up) GW1 = Works as a router, automatically picking the "best" connection between Inet1 and Inet2 (the latter via GW2). GW2 = 5GHz wifi router And here's the problem: H3 only needs internet access when Inet2 is up. What i was thinking of doing was a routing table that looks like this: route to GW2 via GW1 default route is via GW2 I first set the route to GW2 via GW1 without a problem. But when i try route add default gw 1.2.3.4 (1.2.3.4 being the IP of GW2), it complains "SIOCADDRT: No such device" Is the problem that the default gw i'm trying to set is not reachable directly? Is there a different approach that would allow me to achieve this? An alternative (and hypothetical) approach: Since H3 will be using a static IP, is it possible to do some magic with iptables on GW1 to forward any packets from H3 to GW3, thereby "tricking" H3 into using GW2 as its default router?

• Cannot establish a network connect to VMWare Fusion VM

  - by twolfe18

  I am running Snow Leopard 10.6.2 (not the server edition) with VMWare Fusion 3.0.0 and I trying to get my Ubuntu 9.10 x86_64 VM working. I am using a bridged connection, and I have an internet connection FROM the Ubuntu VM (I can download updates, ping websites, etc), but I cannot connect TO the Ubuntu box from any other device on my network. I am trying to get Mongrel up on the Ubuntu VM for some Rails stuff, but it's not working. I know Mongrel/Rails is not the problem because if I start the server on the Ubuntu VM, background the process, and then wget the index page, it works. I just cannot connect to the site from another IP. I have tried using a static IP and a DHCP IP configuration on the Ubuntu VM, neither work (for incoming connections, both work for outwards). I have port scanned the Ubuntu VM, and it appears that all ports are closed. However, the Ubuntu VM does respond to pings. I noticed a similar question here: http://serverfault.com/questions/99757/setting-up-a-bridged-network-with-vmware-fusion, but no answer. Any ideas?

• Linksys WAP54G v3.1 no access, power and link LED solid

  - by user142113

  I'm managing the Network of a small enterprise. A Linksys WAP54G v3.1 used to provide the WiFi network. I was called, because the device did not provide a WiFi network anymore. I first of all tried to ping the device via LAN, but there was no reaction. I've frequently reconnected the AP to the mains and always the POWER and the LINK LED keep solid, even if no network cable is connected. What I've done yet: Reset as documented: Pressed the RESET button for 10 seconds. After that I have tried to access the AP with a direct cable connection to my computer, that I've set to a static ip of 192.168.1.240, but i got no ping response on the default IP 192.168.1.245. Furthermore ipconfig reports "media disconnected". More complex reset method as described here http://bruceshankle.blogspot.de/2005/12/how-to-reset-linksys-wap54g.html as well had no effect. also tried to ping 192.168.1.1 without success Tried this method: http://www.daniweb.com/hardware-and-software/networking/threads/142437/linksys-wireless-access-point-problem#post680245 but there was no ping response when powering up. As well the tftp transfer timed out Finally tried to short pin 15 and 16 of the flash chip on the bottom side of the AP mainboard while booting to provoke a Checksum error. This should lead to the possibility to upload a firmware with tftp, as the AP stops booting and waits for a tftp connection on 192.168.1.1. But I've had no success. As well i've put pin 15 and 16 to ground while booting, also without an effect. After all that I still can't ping the AP, ipconfig still tells me "media disconnected". The POWER and LINK LED are solid. I would appreciate your answers

• Cannot connect on TFS 2012 server through SSL with invalid certificate

  - by DaveWut

  I saw the problem on some forums and even here, but not as specific as mine. So here's the thing, So I've configured a TFS 2012 server, on one of my personnel server at home, and now, I'm trying to make it available through the internet, with the help of apache2 on a different UNIX based, physical server. The thing is working perfectly, I don't have any problem accessing the address https://tfs.something.com/tfs through my browser. The address can be pinged and I do have access to the TFS control panel through it. How does it work? Well, with apache2 you can set a virtual host and set up the ProxyPass and ProxyPassReserver setting, so the traffic can externally comes from a secure SSL connection, through a specified domain or sub-domain, but it can be locally redirect on a clear http session on a different port. This is my current setup. As I already said, I can access the web interface, but when I'm trying to connect with Visual Studio 2012, it can't be done. Here's the error I receive: http://i.imgur.com/TLQIn.png The technical information tells me: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. My SSL certificate is invalid and was automatically generated on my UNIX server. Even if I try to add it in the Trusted Root Certification Authorities either on my TFS server or on my local workstation, it doesn't work. I still receive the same error. Is there's a way to completely ignore certificate validation? If not, what's have I done? I mean, I've added the certificate in the trusted root certificates, it should works as mentioned on some forums... If you need more information, please ask me, I'll be pleased to provide you more.

• Socket options for a tcp server with 3G clients & frequent disconnections

  - by Joel

  I have a TCP server, written in java, sending and receiving many short messages, from 500 bytes to 100 KB long. It's a chess game and chat server, to make it simple. The server is running Debian 6. Half of the clients are connecting from 3G networks, and half over standard DSL. A portion of the 3G clients lose connection pretty often. The error I get on the server and on the client socket is Connection reset. I have come across this page at Oracle documentation: socketOpt. I am wondering what I could tune there to lower the number of disconnections from 3G clients. I don't mind about the ping or transfer rate, but just about the TCP disconnections. I am not skilled enough to understand the impact of each setting, but I sort of understood that the TCP window was important, although I don't know exactly how. So I'm asking if anyone here has an idea ? Thanks if you can help.

• Mac OS X L2TP VPN won't connect

  - by smokris

  I'm running Mac OS X Server 10.6, providing an L2TP VPN service. The VPN works just fine when connecting from all computers except one --- this one computer stays at the "Connecting..." stage for a while, then says "The L2TP-VPN server did not respond". In the console, I see this: 6/7/10 10:48:07 AM pppd[341] pppd 2.4.2 (Apple version 412.0.10) started by jdoe, uid 503 6/7/10 10:48:07 AM pppd[341] L2TP connecting to server 'foo.bar.baz.edu' (256.256.256.256)... 6/7/10 10:48:07 AM pppd[341] IPSec connection started 6/7/10 10:48:07 AM racoon[342] Connecting. 6/7/10 10:48:07 AM racoon[342] IKE Packet: transmit success.

(Phase1 Retransmit). 6/7/10 10:48:17 AM racoon[342] IKE Packet: transmit success. (Phase1 Retransmit). ...and the "retransmit" messages continue until the error message pops up. So far I've unsuccessfully tried: rebooting deleting the VPN profile and recreating it verifying the client's internet connection (it is able to reach the VPN server) connecting through several different networks (in case a router was blocking VPN packets) disabling the Mac OS X Firewall on the client making sure that the VPN settings exactly match those of other working computers running software update (the client is on 10.6.3) Any ideas?

• Certain SFTP user cannot connect

  - by trobrock

  I have my Ubuntu Server set up so users with the group of sftponly can connect with sftp, but have a shell of /bin/false, and they connect to their home directories. This is working fine with three of the user accounts I have. But I added a new user account today the same way that I added the others and it will not successfully connect. sftp -vvv user@hostname debug1: Next authentication method: password user@hostname's password: debug3: packet_send2: adding 48 (len 73 padlen 7 extra_pad 64) debug2: we sent a password packet, wait for reply debug1: Authentication succeeded (password). debug2: fd 5 setting O_NONBLOCK debug3: fd 6 is O_NONBLOCK debug1: channel 0: new [client-session] debug3: ssh_session2_open: channel_new: 0 debug2: channel 0: send open debug1: Requesting [email protected] debug1: Entering interactive session. debug1: channel 0: free: client-session, nchannels 1 debug3: channel 0: status: The following connections are open: #0 client-session (t3 r-1 i0/0 o0/0 fd 5/6 cfd -1) debug3: channel 0: close_fds r 5 w 6 e 7 c -1 debug1: fd 0 clearing O_NONBLOCK debug3: fd 1 is not O_NONBLOCK Connection to hostname closed by remote host.

• BES 5.0 SSL Certificate

  - by Superfly

  I have recently installed BES 5.0 on a Hyper-V (i know it's not officially supported) 64-bit Server 2008 box with a remote SQL 2005 database. I successfully installed and was able to access the Blackberry Administration Service but was getting untrusted certificate errors so I followed the documentation for importing CA and BAS certificates with the Java keytool. They imported successfully but now the BAS webpage shows a "page cannot be displayed" error. TSupport is no help at all. Any ideas?

• Detecting upload success/failure in a scripted command-line SFTP session?

  - by Will Martin

  I am writing a BASH shell script to upload all the files in a directory to a remote server and then delete them. It'll run every few hours via a CRON job. My complete script is below. The basic problem is that the part that's supposed to figure out whether the file uploaded successfully or not doesn't work. The SFTP command's exit status is always "0" regardless of whether the upload actually succeeded or not. How can I figure out whether a file uploaded correctly or not so that I can know whether to delete it or let it be? #!/bin/bash # First, save the folder path containing the files. FILES=/home/bob/theses/* # Initialize a blank variable to hold messages. MESSAGES="" ERRORS="" # These are for notifications of file totals. COUNT=0 ERRORCOUNT=0 # Loop through the files. for f in $FILES do # Get the base filename BASE=`basename $f` # Build the SFTP command. Note space in folder name. CMD='cd "Destination Folder"\n' CMD="${CMD}put ${f}\nquit\n" # Execute it. echo -e $CMD | sftp -oIdentityFile /home/bob/.ssh/id_rsa [email protected] # On success, make a note, then delete the local copy of the file. if [ $? == "0" ]; then MESSAGES="${MESSAGES}\tNew file: ${BASE}\n" (( COUNT=$COUNT+1 )) # Next line commented out for ease of testing #rm $f fi # On failure, add an error message. if [ $? != "0" ]; then ERRORS="${ERRORS}\tFailed to upload file ${BASE}\n" (( ERRORCOUNT=$ERRORCOUNT+1 )) fi done SUBJECT="New Theses" BODY="There were ${COUNT} files and ${ERRORCOUNT} errors in the latest batch.\n\n" if [ "$MESSAGES" != "" ]; then BODY="${BODY}New files:\n\n${MESSAGES}\n\n" fi if [ "$ERRORS" != "" ]; then BODY="${BODY}Problem files:\n\n${ERRORS}" fi # Send a notification. echo -e $BODY | mail -s $SUBJECT [email protected] Due to some operational considerations that make my head hurt, I cannot use SCP. The remote server is using WinSSHD on windows, and does not have EXEC privileges, so any SCP commands fail with the message "Exec request failed on channel 0". The uploading therefore has to be done via the interactive SFTP command.

• Multiple cable adapter setup not working - VGA to smartphone. All cables tested and work

  - by Christopher Rucinski

  Issue Pictured overhead projector setup does not work. #1 - #2 - #3 - Phone. All cables are tested and work! The issue is the HDMI connection between cable #2 and #3. With all other cables, the screen will automatically be displayed onto the projector screen. No extra work needed. With the pictured setup, the smartphone screen is not displayed onto the projector screen. What is the issue with the HDMI connection?? Background We recently had to do presentations at work (school), but the administration only provided VGA means of hooking up to it. Mostly likely reason probably dealt with cost. Anyways, there are several teachers that have brand new Samsung Series 9 ultrabooks (or similar). You know, the ones without VGA support. So I bought an adapter for those ultrabooks. Cable #5 in the picture below. However, both my coworker and I have been wanting to just display our phone screens on the projector. This I knew would require some extra work. What I have VGA cable to projector (cables go through the wall) For laptops HDMI to VGA cable For laptops MHL adapter For 11-pin microUSB phones microHDMI to VGA cable For ultrabooks 11-pin to 5-pin microUSB adapter For older 5-pin microUSB phones) Equipment Projectors 1 projector with VGA and HDMI input (issue is coworkers forget to switch sources) 1 projector with VGA only input Laptops 2 new Samsung ultrabooks w/o VGA or HDMI support 1 ultrabook with VGA and HDMI support several other laptops with at least VGA support 1 tablet with 11-pin microUSB at least 1 new phone with 11-pin microUSB at least 1 old phone with 5-pin microUSB Tested VGA cable (#1) to laptop Good VGA cable (#1) to HDMI adapter (#2) to laptop Good VGA cable (#1) to microHDMI adapter (#5) to laptop Good Projector to HDMI cable (not shown) to MHL adapter (#3) to Galaxy Note 3 smartphone Good VGA cable (#1) to HDMI adapter (#2) to MHL adapter (#3) to Galaxy Note 3 smartphone Does not work!! Extra Notes The 11-pin MHL adapter will not fit inside the 11-pin to 5-pin microUSB adapter so older phones can be displayed on the screen.
