Ubuntu Servers :: Differentiate Between Connections From Windows And Computers
May 21, 2010I have a question about connections with an ubuntu server. Is there a way to know if the terminal computer (which is connected to my linux server) is using WinSCP to connect (on a Windows platform) or a linux system? It seems they are using the same port (22) and I think the exact same protocol (SSH / SFTP), is there a way to differentiate between the two though? And going farther there, is it possible to limit the connections only to linux terminal computers and reject requests coming from Windows computers?

View 1 Replies View RelatedNetworking :: WAN Connections To Servers ?
Mar 1, 2011OK, so, basically, not so long ago I had a modem + LAN cable kind of internet setup, and my friends and colleagues had no problem connecting to my Apache, ircd, etc.
But a few months ago my ISP changed it's policy, and now I have a single cable, plugged directly into the 'eth0' port, which connects to WAN (static IP) and, through PPPoE, to the net (dynamic IP). (Sorry, my knowledge in networking is close to nonexistent)
So, now there is a problem. My friends CAN still connect to my FTP and httpd on Windows XP, through both the external, dynamic IP, as well as the static WAN IP, but my Slackware (WAN IP is set up with DHCP, PPPoE - through pppoe-setup, with firewall at '0') is refusing access. No sings of connection is shown in the /var/log/access_log.
Also, VoiceChatter server DOES log the connection attempt, but it refuses connection, sending a 'Auth challenge', and then cutting connection. (The 'challenge' bit was never there before the new net setup)
All connections are done through WAN static IP (though test with netwide dynamic IP yield the same results =)
I run Slackware 13.1, didn't touch the firewall settings at all, and, as mentioned, pppoe firewall is set to '0' value.
Ubuntu Servers :: 9.10 - Web Connections And SSH Times Out
Jan 28, 2010I am noticing really odd behaviour after upgrading from 8.10 to 9.10 (via 9.04). My server frequently becomes unreachable. I am using it as an application server, running Apache, JBoss and MySql. Once the server goes idle, all web connections time out. SSH also times out. Usually the server wakes up on second SSH attempt and then everything: Web, SSH etc seems to run fine.
This is a server machine with no GUI. Can anyone point me to power management or other such settings I can tune from commandline? I have disabled power management by adding kernel parameter acpi=off. I still have the problem. The first network connection after the machine has gone idle takes a long time. All later connections run pretty smoothly.
Ubuntu Servers :: Proxy For SSL Connections?
Mar 11, 2010I have a small business that I run Squid and Dansguardian on Ubuntu for network proxy filtering, among other things. This works great, but does not block SSL connections on Port 443, such as https proxies. I understand that this is because this type of configuration is a "transparent proxy".
Is there a way to set one up "non-transparent" and, would that filter https?
I cannot blanket block 443, because some sites need it.
I have read that one can re-compile Squid to work with SSL, but not being a super guru, not sure of the implications of doing that.
Fedora Servers :: F10 - Max / Unlimited Internet Connections
Mar 22, 2009When setting up my server I noticed that I could control the amount of connections; the maximum seems to be 256. My server is currently windows 2003 server which is unlimited connections - before I change the server to F10 I need to be able to have unlimited connections (I often go over 256 connections, I have 25 web sites hosted). How do I do this on F10 or is there a better distro for web servers that have thousands of Internet connections at the one time?

Ubuntu Servers :: Allowing Connections From The Outside World Through SSH?
Jan 9, 2010I want to set up my laptop to allow connections to certain users with passwords from anywhere over the internet via SSH but I'm unsure about how I would go about doing this. I only thought it would be the case of setting up the open-ssh server on the laptop then, using my external IP and PuTTY on another PC outside of the network, connect to the external IP through port 22 so I tried this and wait 3 or 4 minutes or so and it says the connection times out.
I have also configured my router to use port forwarding but this doesn't seem to help much either and I have LAMP setup to allow connections to external IP : 80. The only thing I am able to do is access the laptop through the local network by using its internal IP's like 127.198.0.1:22 or something. I was wondering if anybody knows if and could tell me how I would do this as I really want to be able to access my home computer/laptop from my work sometimes, especially if I have work at home which is not with me at work or something.
I know this is possible but I'm quite new to this type of thing and don't know what is going wrong. Have I missed something or do I need to change any .conf files or anything?
Ubuntu Servers :: Samba On Karmic With Two NIC - Connections?
Feb 24, 2010My setup:
Ubuntu Karmic Server Edition 64 bit
Dell PowerEdge T610
4 internal NIC RJ45
1 add-on NIC Fibre 1 Gb
Samba 3.4.0
two shares intended for WIN clients
Connections: eth0 (the first internal NIC) is part of a private network of 4 servers connected to a Gb switch. this connections serves as a fast link among these servers to regularly transfer (backup) large quantities of data. Only I can utilise it from within the server room (among those servers, obviously).
eth0: 192.168.0.AA1 eth4 is the Intel add-on NIC with 1 GB fibre connections to the public network of our institution. This is the link/IP my WIN clints have to use to access their shares. eth4: 134.XXX.YYY.ZZ1
My Problem: Despite having including both interfaces in my smb.conf only the internal connection via eth0 lives up to my expectation and delivers up to 50 MB/s. All clients trying to connect via eth4 will be able to see and access the shares, but file transfers commence with speeds severely below 0,5 MB/s with lots of aborts and warnings from the WIN file explorer.
So I experimented with the setting "interfaces" in the global section of smb.conf --- to no avail. I even set samba only to eth4: same problem. Only way to get flawless & fast transfers is the way through eth0. The samba log files of the clients I tried do show some errors, but I fear I am unable to interpret them properly.
/etc/network/interfaces
Code:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface Intel Gb link via fibre

Ubuntu Servers :: Multiple Connections To SMB Server
May 25, 2010I'm curious how I can use a Windows client with two separate accounts to connect, at the same time, to a SMB server hosting two shares. (Provided permissions and accounts are all in order)
Scenario:User1 is always logged onto a Windows client mapped to a Public share on a Linux SMB server.I need a way to keep User1 connected to the Public share and then when needed, allow User1 to provide User2's credentials to connect to a Restricted share.The only way I've been able to do this is to disconnect from the Public Share then reconnect to the Restricted share using User2's credentials. (This is the issue because I need to keep User1 connected to the Public share).Is this a limitation of SMB? Or am I missing a configuration? Please point me in the right direction
Ubuntu Servers :: How Many Connections Can XAMPP Handle
Jul 23, 2010i would like to know how many connections per sec/min/hour, xampp can handle. I'm going to run SMF forum on my box, because i'm not ready yet with real server solution.

Ubuntu Servers :: Server Can't Make Outgoing Connections
Jul 17, 2011I have a ubuntu 10.04 dedicated server that I am having problems with. It intermittently cannot connect to any other servers outside its network.
Code:
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
^C
--- 8.8.8.8 ping statistics ---
8 packets transmitted, 0 received, 100% packet loss, time 7008ms
(I have tried a bunch of other ips too and none outside its network are pingable) I'm not sure if this is a problem with my server or a problem with the networking outside the server. I have been emailing my server provider and they keep on insisting the problem is with the server and that their network is working fine. Apparently all of their other servers work and they can login into the gateway and ping 8.8.8.8 from there. So they just want to reinstall the OS, but I thought I'd post here to see if anyone has any ideas.
Here is some info I have gained while troubleshooting: I haven't changed any settings at all on the server for months. I haven't done any updates for about a week. The strangest thing is that this is intermittent, there have been a few times in the last 24 hours where I have been able to ping 8.8.8.8 or other ips, but 98% of the time I can't. I have also tried rebooting the server, which had no effect. I can ping the gateway, and I can ping other servers on the same subnet. I can ssh onto the server from my home internet connection, and I can view webpages on apache, so incoming connections work.
Servers :: Ubuntu 10.4 Server Stops Accepting Connections After A Period Of Time / Fix It?
Apr 24, 2011I'm not sure if this belongs in the Server or Networking section of the forums. Anyway, last month I upgraded my server to Ubuntu 10.04 LTS. Since then, I've had a recurring problem wherein after a certain period of time, the server stops accepting network connections. Ubuntu 10 will continue to reject network connections until someone logs into the server locally, after which time network connectivity is restored and the cycle begins anew. Essentially, the server goes into a "half sleep mode". I say half because the computer is still on and the fans are running.
I've done some searching around various forms and initially figured this issue was related to problems with the Network Manager service (https://bugs.launchpad.net/ubuntu/lu...er/+bug/524454), so I removed the service altogether. However, this problem is still occurring.
I've poured over /var/log/messages and /var/log/syslog, but have noticed no irregular behavior. Has anyone else experienced this issues? I'd rather not resort to downgrading back to Gusty Gibbon if I can help it.
I am happy to provide more information if its needed
Networking :: Failed Http And Telnet Connections To Dns Round Robin Servers
Dec 2, 2008So we have DNS round robin set up for 4 servers. If we ping dns name (basically an alias) server_connect it resolves with different IP address in round robin format. I.E. x.x.x.1 x.x.x.2 for the 4 different server IP addresses. When we do nslookup server_connect it will come back first time as server1_connect server2_connect through server4_connect so the server is able to resolve through ping and nslookup resolving the initial dns name (alias) to the dns name associated in the round robin. Problem is when we try to connect with http or telnet it comes back host unrecognized. I can put one of the 4 round robin servers in /etc/hosts and it connects fine so I'm thinking that either one of three things.
1) ttl
2) It does double connection first to identify itself to the round robin server and then handshake but second time it hits for the handshake the IP and dns name is different than what it expected so it fails.
3) Since we are trying to telnet to dns alias and it is returning different dns name it fails.
2 and 3 seem most promising but now I'm at a stand still.Anyone else come across this issue and if so how did you resolve.
OpenSUSE Install :: Unable To Use Remote Connections Like RDP And VNC To Both Windows Machines?
Aug 12, 2010The geek-in-me won and I bought a spiffy little Acer Aspire One netbook, windows 7 starter installed. Now I take it to clients' workplaces instead of my 19" laptop (that I also bought because the geek-in-me won that time too).
So what do I install in the Suse/openSUSE range? I want a lightweight Linux, like Meego or openSUSE with a light Desktop. I need to be able to use remote connections like RDP and VNC to both Linux and windows machines, so maybe Meego can't do that? But maybe openSUSE with a very light Desktop will. I'll use gmail from the netbook, no need for Thunderbird etc. I like to have multimedia.
Ubuntu Servers :: Slow Failure Of Network Connections In Server (as Compared To Desktop)?
Jan 13, 2010I have two ubuntu boxes. One is a 9.04 desktop edition and the other is a 9.10 server edition I am working on some code that needs to be highly tolerant of bad network connections. It sends transactions to a central database, but when the network is not available, it caches them locally to retry later.
I have the code working beautifully on my desktop box. but when I test it on this other box (the one running server edition) there is a HUGE DELAY every time it tries and fails to send a transaction to the database when the network is down.
I tested a little further, and I found that if i unplug my network cable and run ping somehost on the desktop, it fails instantly saying "ping: unknown host somehost" But if I unplug the cable on the server box and run the same ping command it lingers for about 40 seconds before the ping fails.
Does anybody have any idea why this might be happening? Is this a 9.04 vs 9.10 difference? Is this a desktop vs server difference? Is there some package I can install, or some config setting I can change that will make the server box insta-fail just like the desktop does?
Security :: Policy That Limits Connections On Port - Encapsulates Total Sum Of All Connections From Hosts?
Jan 21, 2011Is it fair to say that connLimit and hashlimit are very similiar on Linux i.e. while hashlimit caters to limits for groups of ports, they both set the connection rate limit per host? How in IPTables, do I configure a policy that limits connections on a port that encapsulates the total sum of all connections from all hosts? i.e. I do not want to allow more than 6000conn/minute for port range that is the sum of all connecting hosts?

Apr 1, 2011I'm curious if anybody can shed some light for me in this department. We're in a large environment with a Windows DHCP Server. We have been tinkering with LTSP on Edubuntu as thin and fat clients. It works great, but right now we just have 1 server handling the lab, which works fine unless we want to expand, which may be very possible.
These are the instructions I received:
Login to your windows server and load the DHCP configuration screen
Create a DHCP reservation for the MAC address you obtained
Add the configuration options below to enable the machine to boot from the LTSP server
017 Root Path: /opt/ltsp/i386
066 Boot Server Host Name: <ip address>
067 Bootfile Name: ltsp/arch/pxelinux.0 # Specify CPU architecture in place of 'arch', for instance 'i386'

I'm curious, what if I want to have multiple Ubuntu servers on the network that I want to have bootable? For example, let's say I have 3 labs, and 3 servers. Server A to Lab A, Server B to Lab B, and Server C to Lab C. I want all C's computers to boot to C, and B to B, A to A, etc.
1 - How would I add multiple entries on the Windows DHCP Server to allow all 3 (A B C) servers to boot?
2 - How would I be able to isolate the clients so ONLY Lab A clients boot to Server A, etc?

Ubuntu Servers :: Set Up A Backup Of The Windows 7 Pc?
May 16, 2010I have been hassling with this for several days now. I have 64-bit Ubuntu Server 10.04 running on an Acer Aspire EasyStore H340. I have windows 7 running on a 64-bit desktop pc and on a laptop. I mainly wanted to use the Ubuntu server for a file server, so I installed Samba and created three shares. These do show up in Windows explorer, and I can read and write to them. My windows applications seem to be able to see the shares and open & save files.
My next step was to try and set up a backup of the Windows 7 pc to the Ubuntu server. Windows integrated backup sees the shares and sub-directories within the shares, and the initial part of the backup seems to run OK, but when it tries to save an image of the 'C:" drive it works for a long time and then ends with an error (cannot complete backup).
So, I looked for some free backup programs to try, but these do not allow me to select the shares as a destination (invalid destination). The dialogue sees the drives I have mapped the shares to in Windows, but does not show any sub-directories, and selecting the mapped drive letter does not take as a destination. If I try to browse down through "Network" in the destination dialogue, it selects "Network," but does not expand it or accept it as a destination.
So, I partitioned, formatted as ext3, and mounted my 2nd 1TB SATA drive on the server, and mounted it as "storage." I set this up as share in Samba and gave everyone read-write access, but still no luck selecting it for a backup destination. After some Googling, I downloaded and installed Ext2Fsd-0.48 (a windows 'driver' for Ext2/Ext3). This installed correctly, but when I open the program, neither "Network," the shares, or the mapped drives show up anywhere.
