Ubuntu Servers :: 9.10 - Web Connections And SSH Times Out
Jan 28, 2010
I 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.

while doing FTP through command prompt, connections times out after some time remaining idle, but doing ftp through browser, connection doesn't time out after some time remaining idle... why is it so?

I've done some searching around but can't find anything conclusive on this error. The tech at my remote site restarted the 9.04 server(not sure if it was accidental or planned) and when it started the boot process, an error like the following shows up...
"The display server has restarted 6 times in the past 90 seconds. This indicates that something bad is happening."

At work, we use two very powerful servers to host a series of VMs to do some heavy-lifting analytical work. Part of my job has been to evaluate a variety of different virtualization environments, including changing the host OS (or dom0 kernel for Xen), changing the platform (KVM, Xen, ESXI, etc.), and changing the guest OS types.
I noticed a number of behaviors that Ubuntu exhibited that set it apart (almost always in a positive way) from the other OSes. Most astounding though was that when an Ubuntu 10.04 AMD64 server VM was booted from an Ubuntu 10.04 AMD64 server host (that is, same version of Host OS and Guest OS) in KVM, the guest boots in roughly 2 seconds. At least, the guest boots faster than the VNC connection can initialize.
I'm certainly not complaining, but I can't for the life of me figure out how this could be possible. I understand that the Upstart init daemon is very good about startup times.

When ever i run ssh -p <port> <user>@<remote IP>, i get a connection has timed out error. (i use the -p <port> part because i'm using a custom port). does anyone know what could be causing this? i know of a few *possible* problems, but i don't know how to test them all.
- I am on the same network as the server (I'm trying to test using remote IP to make sure it works before i go out an try it somewhere else)
-The router could be blocking it (i'm using linksys)
-IPtables may not be set up right (i think it is though. the only thing i've run is "sudo iptables -A INPUT -p tcp --dport ssh -j ACCEPT". I have changed the port for the server since then. maybe i have to restart it or something for it to recognise the change? I know very little about IPtables though).
-maybe i have to change something in my client or server config files? (the only config file i've changed is the sshd_config file on the seerver, and that was to change the port to my custom port).
thats all i can think of for now. It may be none of those. I do have the sshd_config and port forwarding in my router set to the same port, so thats good.

I have an embedded server running Ubuntu which is on a network with a lot of wireless AP's. The AP's doesn't support SNMP or anything else, so I monitor if they are up or down by simply pinging them continuously.
My question is if there is anything I could install on the server that could provide me with a webpage where I could see the ping time to the AP's? So it just shows a list of the IP's I have told it to ping, and what their latest response time is. This is what I basically need, but if it were more advanced than that, and could give warnings if ping time were to high etc.

I changed over to U-Verse which means I have a new router, gateway and IPs. Took some doing but everything is working on my server with one exception.Outgoing SMTP mail.I get CONNECTION TIMEOUT when ever something from inside my network tries to hit an SMTP server outside.Any computer within my network does a Telnet (hostname or IP) 25 and I get a time out.Port 25 is open on the router.

I'm using Fedora 12 with Apache 2.2.14, and I was having this error on 2.2.13 as well.
Even when I connect to my server over LAN, Firefox times out occasionally while connecting. I can't figure out what is causing this. The error_log isn't showing anything. I even cleaned the error_log file, so that if something happened, it'd be a little easier to spot. But I'm still getting time outs, and nothing in the error_log.
Here is my httpd.conf [URL]
It's the default Fedora configuration, I've only changed the ServerName if I remember correctly. it's not the Timeout setting, because on LAN it should never time out.

I 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.

I 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?

My 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
auto eth4

I'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

i 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. System stats are: G31M-S2C; 2x2GB Kingston@920Mhz; E5200@3500Mhz; 500GB@7200 Seagate, all powered by Lucid x64. In a time i will migrate to a quad, mobo with raid support, etc. but at that point i'm want to know how much connections can xampp handle. Because of the forum nature, i think of auto deleting topics witn no new replys in 5 days for saving place (there will be minimum 1 and maybe max 5 photos per thread, maximum size 2Mb for each).

What am I missing?
Also I have installed Ngnix so what do I need to do for it to work?

OK, 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.

I 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?

I have slapd-server running but it seems to refuse connections in a very odd way. Wireshark shows that everytime JavaEE-client tries to connect, only 2 packages are sent. As I understand, in tcp/ip protocol, the first is just "hello, who's there". The last is just a message consisting of ACK and RST. I think RST means "we're done". At this point I don't think any credentials are checked so I don't know what could be wrong

I know Ubuntu can do amazing things, but I was wondering if it can use different Internet connections for different websites.
The Setup: We have 1x unshaped ADSL connection at 4MBPS (fastest available) that's used for office related things, Skype, General browsing etc. We have another ADSL connection, this time shaped and running at 4MBPS, I want to send all requests to facebook, twitter and downloading sites like fileserve, filesonic, hotfile etc. to the shaped connection. Can iptables be used to do this? The unshaped ADSL router is connected to eth0 and has an IP of 192.168.0.1 the shaped ADSL router is connected to eth2 and has an IP of 10.0.2.1 Local lan is connected to eth1 and has a range of 192.168.1.0/24 Can iptables send a certain webpage (*.facebook.*) to eth2 and other pages (*.google.*) to eth0 ?

I 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.

When 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?

I tried to set up vnc following the steps of this webpage:
[URL]
which did not work. I changed everything back the way it was, but when I tried to ssh in to my remote server, the connection timed out? It showed nothing in secure logs. I tried to ssh in through webmin, in asked for auth but did not connect. The logs said this:
Jul 30 12:05:10 server sshd[2829]: Did not receive identification string from 209.139.209.100
I tried to telnet port 22 through the shell in webmin and got this:
> telnet 209.139.209.100 22
Trying 209.139.209.100...
Connected to 209.139.209.100.
Escape character is '^]'.
Connection closed by foreign host.
I tried reinstalling ssh, but got the same errors...It worked fine before the howto. I can't imagine how it changed something in ssh...

I'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

I 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?

So 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.

Is 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?
