• Domain Controller died, now get authentication boxes in IE for SDL Tridion 2009

  - by Rob Stevenson-Leggett

  We had a major network issue where our secondary domain controller (responsible for Win2k3 boxes) died and had to be rebuilt (I beleive this is what happened, I am a developer not network admin). Anyway, I am working remotely via VPN at the moment and since this happened, I am getting an authentication box when trying to access certain areas of SDL Tridion via IE (Tridion 2009 SP1 is IE only) it seems like somewhere my credentials are not being passed correctly or the ones cached on my laptop do not match the ones the Domain Controller has. This only seems to affect Windows 2003 servers. Our IT support thinks that the only way to sort it out is to connect my laptop directly to the network. I am not planned to go to the office for a few weeks at least and this issue means I have to work with Tridion via Remote Desktop. We thought changing the password on my account might work but this didn't help. So basically my question is, is there any way I can reset my credential cache without having to reconnect to the network? Or is it IE that is causing the problem perhaps, since I can RDP to servers and use Tridion 2011 instances in other browsers fine? I am on Windows 7 using SonicWall VPN client.

• Network to network VPN Centos 5

  I am trying to follow "http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-vpn.html#s1-ipsec-net2net" I have come up with the following On local router machine: in my ifcfg-ipsec0: ONBOOT=yes IKE_METHOD=PSK DSTGW=10.5.27.1 SRCGW=10.6.159.1 DSTNET=10.5.27.0/25 SRCNET=10.6.159.0/24 DST=205.X.X.X TYPE=IPSEC I have /etc/sysconfig/network-scripts/keys-ipsec0 file in place.

• How to enabled Printer Sharing on Web Server 2008?

  - by FarrEver

  I am installing Web Server 2008 for my home network. I have 2 USB printers that I am connecting to this machine and want to share these printers so that my other machines can print to these 2 USB printers. (I previously had Win Server 2003 on this machine and was able to share both printers fine.) File and Printer sharing Inbound Role for my Private network is enabled, when I go into Network and Sharing Center and try to turn ON Printer Sharing, it never sticks. It always stays on OFF. I go to my installed printers and try to Share them and get the following error message: Printer Settings could not be saved. Remote connections to the Print Spooler are blocked by a policy set on your machine. I have not been able to find a policy on my machine that is preventing this. I have searched a lot over the past few days and most of the results say what I have done should work and there are also a number of search results that say Printer Sharing on Web Server 2008 is not allowed and you have to hack it. Has anyone installed Web Server 2008 and shared printers before? If so, what are the detailed steps you took to get this to work?

• Is there a way to do something like LVM over NFS?

  - by warren

  I realize that since NFS is not block-level, LVM can't be used directly. However: is there a way to combine multiple NFS exports (from, say, 3 servers) into one mount point on a different server? Specifically, I'd like to be able to do this on RHEL 4 (or 5, and re-export the combined mount to my RHEL 4 server). expansion The reason I pegged lvm is that I want a bunch of exported mounts (servera:/mnt/export, serverb:/mnt/export, serverc:/mnt/export, etc) to all mount at /mnt/space so that my /mnt/space on this server (serverx) as one large filesystem. Yes, I know that re-exporting is generally a Bad Thing™ but thought it might work, if there was a way to accomplish this on a newer release as opposed to an older one From reading the unionfs docs, it appears that I can't use it over a remote connection - have I misread it? More accurately, since Union FS merges the contents of multiple branches, but makes them appear as one, it doesn't seem to go in reverse: I'm trying to mount a bunch of NFS points in a merged fashion, then write to them - not caring where data goes, a la LVM .

• Sharepoint (WSS 3.0) on SBS 2008 broken.

  - by tcv

  I recently ran the Sharepoint Products and Technologies Wizard. I had hoped this would bring up Sharepoint and allow me to access it so I could begin to learn. But it's not working. Here is some data that I hope is relevant. I am doing all my testing on the SBS 2008 server itself. I changed the hostheader in IIS to reflect an external FQDN I plan to deploy. The SBS server is remote and there are no domain-connected workstations. If I browse "localhost" SSL, I can get to the site, albeit with a self-signed cert warning. If I attempt to connect via SSL using either the internal FQDN (.local), the External FQDN (.net) or any other permutation thereof, I am prompted for credentials three times but am not allowed access. My account is a domain admin. The site is inaccessible using port 80 whether using localhost, internal FQDN (.local), and external FQDN (.net) Right now, I suspect my problem is within IIS, but I don't know. My plan to publish the sharepoint site to the web so my partner and I can check documents in/out. Can someone help me get started in current direction?

• Can MS Services for Unix be deployed and accessed from a shared drive?

  - by Ian C.

  I'm interested in experimenting with replacing our dependency on MKS with MS' Sevices for Unix toolset. I was wondering if anyone has any experience with deploying SFU on a shared drive? We like to, wherever possible, host our dev tools on one central NAS and call to the NAS to access the tools instead of rolling stuff out to each and every desktop. I'm not interested in the NFS support or ActiveState Perl. Really, none of the daemon technology is required here. I'm looking for replacements for the coreutils/binutils stuff you find in Linux (and MKS on Windows): sed, awk, csh, bash, grep, ls, find -- the meat-and-potates command line apps that our build and test scripts are built around. If I limit the install to just the Interix GNU Components (and maybe the Remote Connectivity components) will is run nicely from a shared location? To head off some questions: Yes, I've looked at Cygwin. Unfortunately it's performance in our build and test environment is poor. It runs considerably slower than MKS and it's not a direct drop-in replacement for MKS (thanks to its internal pathing and limitations with commands like 'ps'), so it's a tougher sell. Yes, I'm looking at the MinGW offering in parallel to this.

• WSS Search fills 10 GB limit on SBS server 2011

  - by Kactus

  I've got a SBS Server 2011 Standard SP1 that isn't very busy. 2 Users local and 2 remote. We have sharepoint that has maybe a dozen small documents at most. I've just started getting the following two error occur Could not allocate space for object 'dbo.MSSBatchHistory'.'IX_MSSBatchHistory' in database 'WSS_Search_SERVER' because the 'PRIMARY' filegroup is full. Create disk space by deleting unneeded files, dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup. And CREATE DATABASE or ALTER DATABASE failed because the resulting cumulative database size would exceed your licensed limit of 10240 MB per database. Digging around in SQL manager I see that WSS Search DB file size is 10241MB, the log file is only 147 MB Firstly, why is WSS Search taking up so much space? How can I stop it from doing so, and what can I do now to get things running ok. I know about log file truncating and this isn't the case here since the log is tiny. Any help is appreciated. There is plenty of free space on the disk (791GB free) Thanks Kactus

• Cannot establish XMPP server-to-server connection to gmail

  - by v_2e

  My jabber-server fails to connect to gmail.com giving the error: outgoing s2s stream myserver.com.ua-bot.talk.google.com closed: undefined-condition (myserver.com.ua is a Google Apps Domain with Talk service enabled.) I am using the Prosody XMPP server. It works just fine with other jabber-servers I tested so far (e.g. jabber.ru). However, when some of my clients tries to add a gmail contact to his contact-list, the subscription request lasts forever, and the Prosody gives the following sequence of messages in its log: Oct 21 22:57:16 s2sout95897f8 info Beginning new connection attempt to gmail.com ([173.194.70.125]:5269) Oct 21 22:57:16 s2sout95897f8 info sent dialback key on outgoing s2s stream Oct 21 22:57:16 s2sout95897f8 info Session closed by remote with error: undefined-condition (myserver.com.ua is a Google Apps Domain with Talk service enabled.)

Oct 21 22:57:16 s2sout95897f8 info sending error replies for 2 queued stanzas because of failed outgoing connection to gmail.com Here for the domain name of my server I use myserver.com.ua I found a similar problem described in this thread, but there is no detailed description of the solution there. As for the Google services, I did have a google account where I added the domain name under question to the Webmasters tools page. However, I deleted my account long ago, so now it is unclear, how any of the Google services can relate to my domain name. So my question is: What is the real cause of this problem (my jabber-server configuration or imaginary Google account or something else) and how can I make my Prosody server connect to gmail.com jabber service?

• Copying compressed files from Server 2008 R2 network share to XP client via VPN fails

  - by Dejan Janjuševic

  At the first sight the question looks similar to this one. I have experienced an odd behavior while trying to copy a certain file from Windows Server 2008 R2 network share to Windows XP Professional client via VPN. The VPN was set up using RRAS on the server machine. I will try to provide as much informations as possible in order to make the issue more clear. When trying to copy the compressed file sized ~2.5 MB (via Explorer or CMD, doesn't matter), the process stalls after some 20%, producing an error message after few seconds: Cannot copy filename: The specified network name is no longer available. If i start the command ping -t 192.168.2.1 (where the IP address specified belongs to the server) side by side with the copy command, I can clearly see that the ping command times out for few seconds as the copy process stalls. When this happens all network activities are frozen. After a few seconds, the network recovers, ping continues to run normally, however the copy process stands still before it displays the above error message. Copying other files (I tried 4-5 files), of which some are larger and some are smaller, succeeds. Seems to me that I can copy all uncompressed files. As soon as I try to copy an archive, the process freezes. Even a 707 KB large archive can't be copied. I can only reproduce this behavior on 2 machines, both Windows XP Professional, one is w/ SP2 and the other w/ SP3. Other XP clients don't have this problem, neither do Windows 7 clients. If I connect to the server using Remote Desktop Connection without using VPN from either of these 2 machines (using the same user account), I can copy anything I want normally, even these "problematic" files. Does anyone have any clue about what could possibly be going on?

• XP SP2 Event log not logging events

  - by Weedfreer

  I have a problem whereby a terminal appears not to be logging events correctly and occasionally appears to have problems communicating accross the network.The terminal has previously been infected with a virus which apears to have 'played' with the default group policy in the standard user profile. Although, outwardly, the terminal appears to be working normally I still have a nagging feeling that it isn't quite back to the way it was. It was infected by a user plugging in a USB Stick while the company was using the older version of the AV software...typically a week or so before it was updated.I have configured the Event logs to Overwrite as required and to be 5056KB in Maximum size. I have also attempted:- Disabling the Event Log service & restarting Renewing the EVT files in Windows\system32\config directory Restarting the event log service and restarting Clearing the event log in the Services MMC Resetting the Filters to Default in the services MMC Using the EVENTCREATE command remotely from a CMD window on the server to force an event creation event. So far the only operation to have any sort of success is the remote computer EVENTCREATE command from a CMD window on the server. As it stands, the only other time that the computer has managed to create events is while it is being restarted.Has anyone gotany ideas on how to proceed? I'm thinking that possibly a refresh of the 'Windows\system32\config\SystemProfile' folder. I'm also thinking about running a tool such as Malwarebytes but this could be slightly controvertial as the system needs to be running on 'up-time' for as long as possible. I'm also wonderign whether anyone knows of any Windows admin tools that allow me to control the event logging options or default security options so that i could get it back to some sort of standard.What I'm trying to avoid is a complte re-imaging of the terminal. Although this is an option, I dont really want to have to take it if i dont need to.Many thanks in advance for any suggestions anyone may be able to provide.

• Ubuntu karmic, chroot, Ubuntu server 8.04 LTS and Plesk

  - by morpheous

  I am pretty new to the Linux environment, and although I have been using Ubuntu Karmic desktop for development work, I have always prefered the GUI tools and very rarely use the terminal. I am about to launch a site (a VPS) which will be running Ubuntu server 8.04 LTS and Plesk. I want to install both the server (8.04 LTS) and Plesk in a 'chroot' on my Karmic desktop. I also want to test install some packages I have written for the server, and generally familiarize myself with the environment before I signup to the hosting service. I will be running a streamline server (no GUI), with only the following software: PHP Python mySQL PostgreSQL Apache Plesk Third party packages I developed In terms of mail, I think the hosting provider provides a mail service, so I dont know if I will need to run my own mail server. I will like some advice on the following: How can I install Ubuntu 8.0.4 server LTS in a chroot? How can I install Plesk in Ubuntu 8.0.4 server LTS (from the command line) Can anyone recommend how I back up the remote server when I go live (i.e. what tools to use)?. I will need to back up both databases, as well as some config data and installation packages

• How to unblacklist an IP at Google?

  - by DJRayon

  I own a small business with two servers for webhosting. When setting up the primary (CentOS 5.5 + WHM, secondary is WHM DNS Only) server I kinda messed up the firewall, so the hackers could send stuff from my server. My primary IP is x.y.29.218. Anyway - I got blacklisted in several places, but now those blacklistings are gone. For a week or so, but Google still has my IP blacklisted. I handling serious damages because of that. Many clients want to switch from my hosting, etc. I've fixed the hole with CSF firewall SMTP_BLOCK option and enabled also the WHM SMTP TEAK Currently all I see from the Main Email View Mail Statistics (Errors section) in WHM is rows and rows of the following message removed-the-email-address-for-security R=lookuphost T=remote_smtp: SMTP error from remote mail server after end of data: host aspmx.l.google.com [a.b.39.27]: 550-5.7.1 [x.y.29.218 1] Our system has detected an unusual rate of\n550-5.7.1 unsolicited mail originating from your IP address.

Please someone, who has any knowledge how to deal with the current situation, please give me some kind of help - any help, suggestions, etc. I've tried everything I know, and I still don't know much, because this is the first time (I just started to webhost, etc) I deal with real physical servers not some kind of pre-setup VPS solution. Many - many thanks, whoever has time to offer some help.

• Windows 8 folder to folder sync software

  - by Danny

  I'm looking for direct folder to folder synchronization in Windows 8. I was previously using Live Mesh to accomplish this, but now it looks like that is no longer an option. Note that I'm talking about direct folder to folder sync between different computers, not syncing to the cloud. I'm aware of products like Google Drive, SkyDrive, Dropbox, etc. The problem with them is the space limitation. Basically, I was syncing important files before between my desktop and all of my laptops. One folder for example is My Pictures. This folder has almost 40 gigs of files, which is why the options listed above are not going to work for me. Just need direct syncing, nothing stored on the cloud. I was told by a Microsoft employee that SkyDrive would be replacing Mesh and would provide all the same functionality. So far this looks to be completely false, since the ability to remote desktop is gone along with folder to folder sync. Unless I'm just missing something?

• LVM and cloning HDs

  - by jcea

  Using Linux, I have several backup levels. One of them is a periodical sector by sector copy (using dd) of my laptop harddisk to an external USB disk. Yes, I have other backups too, like remote rsync. This approach (the disk dd) is OK when cloning a HDD with no LVM volumes, since I can plug the external disk anytime and mount the partitions simply mounting /dev/sdb* instead of /dev/sda*. Trivial and handy. Today I moved ALL my harddisk (including the /boot) to LVM. Everything works fine. I will stress it for a couple of days, and then I will do a sector by sector copy to my external harddisk. Now I have a problem, I guess. If in the future I plug the external USB HDD to recover any file, the OS will detect a duplicate LVM configuration, with the same name and the same UUID. Even doing a vgrename (which LVM would be renamed, the internal HDD or the external HDD?), the cloned UUID will not change. Is there any command to change name and UUID? Ideally I would clone the HDD and then change the LVM group name and its UUID, but I don't know how to do it. Another related issue would be... In the past I have booted my laptop using the external disk, using the BIOS boot menu and changing GRUB entries manually to boot from /dev/sdb instead of /dev/sda. But now my current GRUB configuration boots directly from a LVM logical volume, something like: set root='(LVM-root)' in my grub.cfg. So... What is going to happen with duplicated volumes? Any suggestion? I guess I could repartition my external harddisk and change backup strategy from dd to rsync, but this disk has windows installed too, and I really would like to have a physical "real" copy.

• Scroll wheel causes browsers + Windows explorer to go back

  - by KaptajnKold

  I use Windows 7 on a VirtualBox VM on a Mac. Lately, when I'm using any browser (IE9, Chrome or FireFox or even Windows Explorer), use of the scroll wheel followed by any movement of the mouse cursor causes the browser to go back. Very annoying. This happens when I use the scroll wheel on a USB connected mouse (brand/model unknown, since I don't have it in front of me as I write this) or when I use two-finger scrolling on the trackpad when no mouse is connected. When I connect from my VM to a remote Windows box (Windows Server 2008), I experience the same problem. I have tried rebooting the VM to no avail. I am not sure when the problem started exactly. It may or may not have been after I connected the USB mouse for the first time, but trying to unplug it and then rebooting didn't help. I have tried to google for a solution, but all I've found are people who accidentally pressed the shift key while scrolling, which will cause the browser to go backward or forward in the browser history. This however is not the problem I'm having. To be clear, in my case the browser only goes back when I move the mouse after I've used the scroll wheel. I'm at my wits end :(

• Multiple static WAN IP addresses to single LAN subnet

  - by Jessy Houle

  Below is my home network topology. I currently have 5 static IP addresses, 3 of which are in use by 3 routers. These routers in-turn subnet internal networks and port forward. I use my SSL VPN appliance to remote home from work or on the road. At this point I can remotely administer my Windows Server. I know the network is setup wrong, I was matching existing hardware the best I knew how. http://storage.jessyhoule.com.s3.amazonaws.com/network_topology.jpg Ok this said, here is the problem... One of my websites on my Windows Server now needs to be secure (SSL using port 443). However, I'm already port forwarding port 443 to my VPN appliance. Furthermore, if I'm going to have to reconfigure the network, I would really like to be able to use the SSL VPN to remotely administer all machines. I mentioned this to a friend of mine, who said that what I was looking for was a firewall. Explaining that a firewall would take in multiple static (WAN) IP addresses, and still allow all internal devices to be on the same network. So, basically, I could supply my SSL VPN appliance it's very own static (WAN) IP address routing, and yet have it on the same internal network (192.168.1.x) as all my other devices. The first question is... Does this sound right? Secondly, would you suggest anything different? And, finally, what is the cheapest way to do this? I am started down the road of downloading/installing untangle and smoothwall to see if they will do the job, hoping they take multiple static (WAN) IP addresses. Thank you in advance for your answers. -Jessy Houle

I've tried the various scripts mentioned in the links below but to no avail: http://simplygenius.com/2010/08/jconsole-via-socks-ssh-tunnel.html http://gabrielcain.com/blog/2010/11/02/using-ssh-proxying-to-connect-jconsole-to-remote-cassandra-instances/ I'm running ssh -f -ND 8123 myuser@mymachine and verified that at least Firefox goes through it as a proxy. I then run jconsole -J-DsocksProxyHost=localhost -J-DsocksProxyPort=8123 service:jmx:rmi:///jndi/rmi://ec2-XX-XX-XXX-XXX.compute-1.amazonaws.com:8080/jmxrmi I run netstat -n on my EC2 instance and I see a connection created by my machine. However, the connection eventually disappears and I get a 'channel 2: open failed: connect failed: Operation timed out' from my ssh tunnel. I've opened the jmx port through the security group and I've checked the port on the EC2 instance to make sure it's open (by telnet-ing to it). I'm not sure where to look next. Are there some properties in sshd_config or ssh_config I need to enable for tunneling? Or anything in Mac OS X? I feel like a serious noob but sys administration is really not my strong point. I've spent several hours and can't get this to work.

• Vlans and subinterfaces

  - by Adeodatus

  I've inherited a moderate size network that I'm trying to bring some sanity to. Basically, its 8 public class Cs and a slew of private ranges all on one vlan (vlan1, of course). Most of the network is located throughout dark sites. I need to start separating some of the network. I've changed the ports from the main cisco switch (3560) to the cisco router (3825) and the other remote switches to trunking with dot1q encapsulation. I'd like to start moving a few select subnets to different vlans. To get some of the different services provided on our address space (and to separate customers) on to different vlans, do I need to create a subinterface on the router for each vlan and, if so, how do I get the switch port to work on a specific vlan? Keep in mind, these are dark sites and geting console access is difficult if not impossible at the moment. I was planning on creating a subinterface on the router for each vlan then setting the ports with services I want to move to a different vlan to allow only that vlan. Example of vlan3: 3825: interface GigabitEthernet0/1.3 description Vlan-3 encapsulation dot1Q 3 ip address 192.168.0.81 255.255.255.240 the connection between the switch and router: interface GigabitEthernet0/48 description Core-router switchport trunk encapsulation dot1q switchport mode trunk show interfaces gi0/48 switchport Name: Gi0/48 Switchport: Enabled Administrative Mode: trunk Operational Mode: trunk Administrative Trunking Encapsulation: dot1q Operational Trunking Encapsulation: dot1q Negotiation of Trunking: On Access Mode VLAN: 1 (default) Trunking Native Mode VLAN: 1 (default) Administrative Native VLAN tagging: enabled Voice VLAN: none Administrative private-vlan host-association: none Administrative private-vlan mapping: none Administrative private-vlan trunk native VLAN: none Administrative private-vlan trunk Native VLAN tagging: enabled Administrative private-vlan trunk encapsulation: dot1q Administrative private-vlan trunk normal VLANs: none Administrative private-vlan trunk private VLANs: none Operational private-vlan: none Trunking VLANs Enabled: ALL Pruning VLANs Enabled: 2-1001 Capture Mode Disabled Capture VLANs Allowed: ALL Protected: false Unknown unicast blocked: disabled Unknown multicast blocked: disabled Appliance trust: none So, if the boxen hanging off of gi0/18 on the 3560 are on an unmanaged layer2 switch and all within the 192.168.0.82-95 range and are using 192.168.0.81 as their gateway, what is left to do, especially to gi0/18, to get this working on vlan3? Are there any recommendations for a better setup without taking everything offline?

• Msg 10054, Level 20, State 0, Line 0 Error when altering a stored procedure to add a couple of curso

  - by doug_w

  We have a home-rolled backup stored procedure that uses xp_cmdshell to create and clean up database backups. We have an instance that is 2005 sp3 that we are trying to deploy this script to. I am at a bit of a loss for why it is not working. When I execute the create it runs for about 30 seconds and yields the following error: Msg 10054, Level 20, State 0, Line 0 A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.) In my tinkering I discovered that by removing the cursors that actually do the work it will allow me to create the stored procedure (not very helpful for me though). If I add the cursors back in using an alter the error returns. I would be curious if someone has experienced this problem and knows of a solution or work around. I am not opposed to posting the source, it is just lengthy. Things I have checked: Error Logs No dump files in the log directory Thanks in advance for the help.

• pppd disconnects from 3G, doesn't reconnect, w/ persist set

  - by bytenik

  I am trying to configure pppd to connect to a 3G network (Sprint, in this case) and then stay connected, reconnecting automatically if the remote connection is terminated. I have enabled the persist option. My configuration file is as follows: hide-password noauth connect "/usr/sbin/chat -v -f /etc/chatscripts/cellular" debug /dev/cell 921600 defaultroute noipdefault user " " persist maxfail 0 lcp-echo-failure 10 lcp-echo-interval 60 holdoff 5 However, when the peer disconnects the connection, pppd often waits a long time (substantially more than my holdoff) to reconnect the modem -- if it ever reconnects at all! An example log showing this: May 23 05:17:24 00270e0a8888 pppd[2408]: rcvd [LCP TermReq id=0x26] May 23 05:17:24 00270e0a8888 pppd[2408]: LCP terminated by peer May 23 05:17:24 00270e0a8888 pppd[2408]: Connect time 60.1 minutes.

May 23 06:08:10 00270e0a8888 pppd[2500]: using channel 11 The disconnect at the request of the peer occurs at 5:17, but the reconnect didn't happen until 6:08. I had a friend monitoring the server so I'm not certain that this wasn't a manual reconnection. Either way, it either took almost an hour to reconnect or never reconnected. Shouldn't persist + holdoff 5 cause this to automatically reconnect after 5 seconds of the link terminating?

• "Safe" personal router use on apartment-wide network

  - by noisetank

  I recently moved into an apartment with internet included in my rent. This was a boon at first, but now I'm feeling limited. To get devices connected (wired or wireless), I have to whitelist the MAC addresses on mycampusnet.com. This is annoying (considering I'm well over the 10 device limit including my roommate's stuff), but what's really driving me mad is that I don't seem to have any semblance of a "local" network. I've relied heavily on static IPs and port forwarding in the past (accessing NAS and remote desktop) and (as far as I can understand), that functionality is nonexistent without my router set up. Also, as my wired and wireless devices don't always seem to make it onto the same subnet, I'm unable to use any of my iDevices with my Apple TV (I can, however, mirror to no less than four strangers' Apple TVs at any moment, which is a whole other level of discomforting). I've talked to the head of the apartment complex and she told me that they personally don't have any issue with my using a router, but the provider (CampusConnect) does not currently allow it. Apparently, enough people have put in complaints/requests about the restriction (the apartments are for graduate students and University staff, many of which need to set up things like VPNs for work reasons) to open up some sort of ticket to get the functionality in place, but all the calls I've made to get status updates have been a waste of time. My question is: If I plugged my router into the apartment network, what would happen? I've been told already that personal routers would "interfere with the wireless" and that they would shut my port down if I used one, but is that a legitimate thing or just something made up that sounds real to keep the average Joe from pushing it further? I'm guessing there's some way of configuring my router to keep it from disrupting the rest of the network, but it's not something they want to tell me for obvious reasons. Am I right? And if so, what are the chances that they'd notice the difference in traffic or whatever and shut off my port?

• port forwarding with socks over proxy

  - by Oz123

  I am trying to browse a wiki that runs on a server inside one domain from another domain. The wiki is accessible only on the LAN, but I need to browse it from another LAN to which I connect with an SSH tunnel ... Here is my setup and the steps I did so far: ~.ssh/confing on wikihost: Host gateway User kisteuser Port 443 Hostname gateway.companydomain.com ProxyCommand /home/myuser/bin/ssh-https-tunnel %h %p # ssh-https-tunnel: # http://ttcplinux.sourceforge.net/tools/stunnel Protocol 2 IdentityFile ~/.ssh/key_dsa LocalForward 11069 localhost:11069 Host server1 User kisteuser Hostname localhost Port 11069 LocalForward 8022 server1:22 LocalForward 17001 server1:7100 LocalForward 8080 www-proxy:3128 RemoteForward 11069 localhost:22 from wikihost myuser@wikihost: ssh -XC -t gateway.companydomain.com ssh -L11069:localhost:22 server1 on another terminal: ssh gateway.companydomain.com Now, on my companydomain I would like to start firefox and browse the wiki on wikihost. I did: [email protected] ~ $ ssh gateway Have a lot of fun... kisteuser@gateway ~ $ ssh -D 8383 localhost user@localhost's password: user@wikiserver:~> My .ssh/config on that side looks like that: host server1 localforward 11069 localhost:11069 host localhost user myuser port 11069 host wikiserver forwardagent yes user myuser port 11069 hostname localhost Now, I started firefox on the server called gateway, and edited the proxy settings to use SOCKSv5, specifying that the proxy should be gateway and use the port 8383... kisteuser@gateway ~ $ LANG=C firefox -P --no-remote And, now I get the following error popping in the Terminal of wikiserver: myuser@wikiserver:~> channel 3: open failed: connect failed: Connection refused channel 3: open failed: connect failed: Connection refused channel 3: open failed: connect failed: Connection refused Confused? Me too ... Please help me understand how to properly build the tunnels and browse the wiki over SOCKS protocol. update: I managed to browse the wiki on wikiserver with the following changes: host wikiserver forwardagent yes user myuser port 11069 hostname localhost localforward 8339 localhost:8443 Now when I ssh gateway I launch Firefox and go to localhost:8339 and I hit the start page of the wiki, which is served on Port 8443. Now I ask myself is SOCKS really needed? Can someone elaborate on that ?
