Ubuntu Servers :: VPN Setup Peer Negotiation Failed

May 23, 2011

I've followed [URL] to set up vpns with some external networks. So far it worked like a charm on two of them. But when trying to connect to the third one I instantly get bumped off.

When running
pon dymka debug dump logfd 2 nodetach

I get this as part of my output
CHAP authentication succeeded
sent [CCP ConfReq id=0x1 <mppe +H -M +S -L -D -C>]
rcvd [IPCP ConfReq id=0x26 <addr> <compress VJ 0f 00>]

rcvd [CCP ConfReq id=0x3e <mppe -H -M +S -L -D -C>]

rcvd [CCP ConfNak id=0x1 <mppe -H -M +S -L -D -C>]

rcvd [LCP TermAck id=0x66]

Waiting for 1 child processes...
script pptp xxx.xxx.xxx.xxx--nolaunchpppd, pid 8920
Script pptp xxx.xxx.xxx.xxx --nolaunchpppd finished (pid 8920), status = 0x0

I've looked all over the internet but sollutions like adding mmpe-stateful to options.pptp doesn't work. Is this a problem with the client or with the server? Because the server is configured just like the other two and they work as intended. Seemed to be a problem on the firewall.

Networking :: TLS Error: TLS Key Negotiation Failed To Occur Within 60 Seconds

Jan 24, 2011

i set up openvpn on server and configure it then create license file for client and done the rest but when the client want to connect i got the following error :

TLS Error: TLS key negotiation failed to occur within 60 seconds

and now the strange part is if i connect my pptpd connection ( which runs on another server ) and then connect openvpn again i connect instantly without any problem or error in my country im sure there is heavy firewall on all outgoing traffic but currently i do not understand what can cause this problem
i ran tcpcump and seems server receive packets and send it back to client ( though im not sure if client can get the response ) this is my server.conf


local myserver ip #Replace with your server IP address
port 443 #Replace with the desired port
proto udp #Choose between tcp and udp (remove instructions in bold)

Ubuntu Networking :: Peer To Peer Filesharing Between PC's

Mar 2, 2010

I know I'm missing something absolutely basic here but when I search the forums for filesharing I only seem to get info referring to Windows filesharing/SAMBA etc.

We have 3 Ubuntu machines at home and a printer on a Windows machine. How can we best fileshare:

1) between Ubuntu machines
2) reliably between Ubuntu and the Windows machine

Printing across the network is ok except for the Karmic NBR machines but that's another thread.

Ubuntu Networking :: Ssh "Connection Reset By Peer" - Write Failed: Broken Pipe

Feb 9, 2010

which cropped up today after no changes to the system: I can successfully ssh into my ubuntu 64-bit 9.10 machine (via OS X with iTerm), but after about 30 seconds, the connection drops with the message "Connection reset by peer Connection to xx.xx.xx.xx closed".

If I then try to immediately ssh back in I get: "Write failed: Broken pipe". If I try to immediately ping the machine instead, I cannot ping it until the ~10th try. Eventually I can log back in again, only to be kicked off after between 5 and 60 seconds. I called the network people and their are no known issue right now with networking. The networking on the ubuntu machine is otherwise fine, it seems. In the /var/log/auth.log file, it simple says:

Feb 9 14:19:20 harriet sshd[4134]: Accepted password for xxx from xx.xx.xx.xx port 55105 ssh2
Feb 9 14:19:20 harriet sshd[4134]: pam_unix(sshd:session): session opened for user xxx by (uid=0)
Feb 9 14:19:28 harriet sshd[4046]: pam_unix(sshd:session): session closed for user xxx

The solution I come across to a similar problem is to add a "ClientAwakeInterval" number to sshdconfig, but this (as expected) doesn't fix my problem.

Fedora Networking :: Turning Off Auto Negotiation?

Aug 24, 2010

Im trying to maximize my network connectivity. To do this I have begun using the program ethtool. The first thing I did was run

#ethtool eth0
which informed me Im running 10BaseT mode. So i though, ok, that has to do with the autoneg right?
so I ran:
# ethtool -s eth0 speed 1000 duplex full autoneg off


LOLz, I got it now, This computer has 2 nics installed! Thats why the link stat was "Link detected: no"
I moded my code to pertain to eth1, the connected port. Eh, anyhow, Im still not sold on this problem being solved, the connection eth1 seems to work fine at 100BaseT/Full but I loose connectivity when trying to use 1000BaseT/Full despite the nic showing it as a supported mode.

Ubuntu Servers :: Setup New Remote Office - Setup Domain Trust Between Two Sites?

Mar 14, 2010

I ended up setting up a basic linux file server as a pdc for that office. Our main office is a windows 2000 ads domain. The two offices are connected with a vpn. I only have two users at the new location so I simply have the linux and samba usernames/passwords setup manually. I would like to know if it is possible to setup a domain trust between the two sites so I don't have to create a username/password in the remote site for every user at the main office to access. I did some searching but came up empty.

Ubuntu Networking :: GPRS - LCP Terminated By Peer

Nov 20, 2010

I am trying to get pppd/chat working with an internal Wavecom modem, but PPP terminates with message "LCP terminated by peer". But, same pppd/chat configuration is working on my own Linux OS with Huawei 3G modem. I tried several options to get it working, but no luck. The problem is happening during the PPP negotiation with the Modem:

rcvd [LCP TermReq id=0x2]
LCP terminated by peer

But this only mean that there was a failure during PPP setup between Linux and the Modem. I tested the modem with manual AT commands via minicom to further investigate to problem, but could not even activate the PDP context:

Modem is registered and attached to Vodacom's network:

+COPS: (2,"VodaCom-SA","VODA","65501"),(3,"MTN-SA","MTN","65510"),(3,"","","65502"),(3,"Cell C","C)

Ubuntu Networking :: Rdesktop Connection Reset By Peer

Jul 15, 2010

I've happily been using rdesktop to access my MS Vista desktop from Ubuntu (Hardy) for a few months until a couple of days ago when it stopped working. Now if I try connecting I get the following:


I don't believe anything's changed on the client (Ubuntu) side. The Vista box is occasionally connected to a corporate intranet via VPN and it was after such a session that rdesktop stopped working, so perhaps a Windows group policy was modified during the session. I've checked the basics - can ping from Ubuntu, can access port 3389. Have deleted ~/.rdesktop and ~/.tsclient.

Digging around the Vista client I noticed in Control Panel > System Properties > Remote that in the Remote Desktop sub-panel the Allow connections only from computers running Remote Desktop with Network Level Authentication setting is enabled and that the other two are greyed out. Now, I don't know whether this setting has been changed but I suspect that it might be the problem.

Unfortunately, I don't know enough about Windows to know how or even whether I can change this setting to Allow connections from computers running any version of Remote Desktop (less secure) I've poked around the group policy editor (gpedit.msc) but no joy.

Fedora Networking :: 3G USB Modem - LCP Terminated By Peer

Sep 7, 2009

I recently upgraded to Fedora 11, and am having an issue with the USB modem (Novatel USB720) disconnecting almost immediately after it is connected. Sometimes it disconnects 30 seconds after it is connected, sometimes 2-3 minutes. And other times it stays connected for hours without a problem. I know the card is good as it works using Verizon Connection Manager software under Windows and never had this problem.

And, I am able to get to the Internet while it is connected, so it is passing traffic OK. I'm using the NetworkManager to connect the "Auto Mobile Broadband" connection. I've seen other posts on this very same issue, and I verified that pppd is called using the "lcp-echo-failure 0" and "lcp-echo-interval 0" options. But it seems that when it does disconnect, in /var/log/messages it says "LCP terminated by peer".

Below is an example of /var/log/messages where we can connect, then it immediately disconnects.

OpenSUSE Network :: KDE Hangs When Peer On Nfs Is Offline?

May 27, 2011

I have a couple of nfs shares which I configured through the yast NFS client module. It entered these in my fstab file to start on bootup. A sample entry is: 0 0

As long as the foreign computer is online all is well. If the foreign computer is taken off line, soon after KDE applications such as Dolphin and the panel freeze, even if I am not using the shares. When the foreign computer comes online again, everything unfreezes on my computer and works fine. Likewise, if the other computer is not online when I boot, there is a long delay while the system waits for the share to come up. Is there something in my configuration that I can change to stop either or both of these problems? I am running 11.4 x86_64 on a wired network with static ip addresses.

Fedora :: YUM Freezes With Error - Peer Certificate Invalid

Sep 17, 2010

My organization just moved to using a zscaler proxy system. Basically, I have to use a .pac file in Firefox to get onto the proxy, which directs me to a series of two Flash pages, one to input my username, one for the password. After reading through the .pac file, I was able to get some command-line things to work by specifying the proxy given at the end. However, this server uses an SSL certificate that is not emitted by an authority, but rather directly by our organization. In Firefox, I had to import this certificate to enable https:// browsing.

Is there any way to "import" this certificate so that yum can use it? Because yum freezes with the error:
Could not get metalink [URL] error was
14: Peer cert cannot be verified or peer cert invalid

Ubuntu Servers :: Setup More Than 2 Sub Domains On 9.10?

Jan 29, 2010

I've built a web hosting server with ubuntu 9.10 desktop edition at home and it's up and running.how to get and set subdomains. What I mean is that I have a purchased domain [URL] and I want to add as many sub domains as I want such as [URL] so on. And more importantly every single subdomain must belong to each account.

sub domain      account name
sub1.example.com   john
sub2.example.com   steave
sub3.example.com   myname

In this case, there are three accounts for ubuntu and each account has a permission to the corresponding sub domain only. p.s My DNS is managed by my domain company and it provides a web page where I can forward(not sure, but there are fields that I can type my sub domains) subdomains and my external IP addresss up to 20(just in case this info matters).
