Networking :: Cannot Get A Response From Server As Get A Unauthorised Message
Aug 4, 2010
Have a Java program which simply connects to a server and gets back the response from the website.
When I use it under Windows environment it runs fine and i receive a Response Code: 200,
Response Message: OK but in UNIX i get Response Code 401, Response Message Unauthorized
In Unix I tried to ping the website using the ping command.
I use putty to connect to a Unix m/c. I don't have any permissions to install any programs so could not install any s/w so i could check if i were able to reach the website.
Is it a Proxy Server related issue ? If yes how do i configure it ?

Whenever I make an ssh connection to my Fedora 14 server, the echo of my keyboard strokes are very jerky. It will echo a few, then stop for a moment, then it echos all the keyboard entries from the time it stopped responding all at once. Anyone have any ideas on why this started happening? This happens from any computer I use to connect. It happens with Putty and SSH Secure Shell.

I can connect to the internet and browse. I'm wired and using DHCP on a Windows network. Updating Ubuntu or downloading programs takes hours for 52MB of updates. Why? I read some articles that mention Network Manager needs to be enabled at the .conf file. Can I edit this using GUI or command line only?

I have followed this guide [URL] to setup a diskless cluster based on ubuntu server. Every thing is fine in the boot process except this:
After the client boots vmlinuz and init.rd, I see some information and after a minute I see:
Code:
IP-Config: no response after 60 secs - giving up
/init: .: line 3: can't open /tmp/net-eth0.conf
kernel panic - not syncing: Attempted to kill init!
It is strange since it gets an ip address when it want to boot. I don't know what is wrong with it.

I have installed Centos 5.4 with Sendmail 8.13.8, i have modified sendmail.mc file and compiled to sendmail.cf with following lines
1. TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')
2. Define define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
3. DAEMON_OPTIONS(`Port=smtp, Name=MTA')dnl
My problem is that when i try to open port 25 with telenet it takes lot of time like more than 1 minute to open session and another 30 - 40 seconds to respond to "ehlo" command.
Also when i try to open telnet session on port 25 in another server it hardly takes 1-2 seconds open session.

For example when i use nslookup or dig command to query Yahoo.com the response from server maybe deliver about 5 Sec or become timed out , but sometimes response time less than 1 sec!
I don't know why, perhaps kernel works week so i decided to do the following :
But the problem didn't solved
I previously had Freebsd with same version of bind and same configuration and everything worked fine.

I try to connect to my server (whose IP is x.x.x.x below) from my laptop. I have no idea why openvpn client won't work this time. It works fine in win7 before. I re-installed openvpn but it doesn't work neither. Then I searched for this issue, find that it is possibly caused by disabled DHCP Client service. I checked, and found it was enabled. Still won't work after restarting dhcp client service.
Basic Info:
OS: Windows 7
OpenVPN client: openvpn-2.2.0
DHCP Client Service started.
The following is the log during connecting:
Code:

I have a perfectly working installation of nginx / PHP / fastcgi on the latest stable Debian distribution. No problems at all, apart from this one: When a PHP script (script A) is written to request a PHP script on the same web server (script B), nginx takes several minutes to respond and finally the connection times out. And it happens only when invoking script A through nginx. Calling it from command line works fine � I get a normal output of script B.
Literally, the test case is as simple as:
Script A:
PHP Code:
[code]....
I suppose the root of the problem may be some obstacle occurring when php5-cgi ends up invoking itself. And this is what happens when script A is called through nginx. But I have no ideas yet how to address the problem. One of my PHP applications checks itself during installation, that's why I need to request a PHP script from a PHP script on the same server.

I have a problem concerning the vacation(auto response). I got a mailserver(smtp.mydomain.com), pop3/imap-server(mail.mydomain.com) webserver(www.mydomain.com, with postfixadmin on it). I use Debian 5.0 So it's like this, I receive mail to smtp.mydomain.com, it get checked for spam with amavisd-maia(Maia Mailguard), then delivered to the pop3/imap-server. I'm guessing there's something wrong with my postfix setup. I activate auto response for my account, when I get a mail it says this at smtp.mydomain.com:

We're having an issue with HTTP POST file uploads on our two Ubuntu PCs. For some reason, whenever one of our users attempts to submit a file in an HTML form, the request times out, usually with a 500 Internal Server Error message. This problem is not limited to one site, but occurs on all sites that use file uploads. Also, the problem does not appear to be with our network, as a Windows 7 PC on the same network can upload files to the same sites without any difficulties. The problem is not browser-specific; we have tested with Firefox, Epiphany, and Google Chrome and all produce the same results. The issue is relatively new, and was first observed within the last month; before this time, both machines had no problems uploading files.
Does anyone have ANY idea what could be causing this? I've tried a number of things, including rebooting the PCs, rebooting the network, disabling IPv6, etc. I'm not very experienced in Linux system administration, but I can use the terminal and am familiar with some terminal-based diagnostic tools, so if you need any additional info or want me to try something, please let me know! I've exhausted my own computer knowledge with regards to finding a solution to this problem.

I am a new user of Ubuntu...I am trying to use if for a University project. I have installed Ubuntu under a nice new partition and install was smooth. I am using my Belkin F5D8055 v1 USB adapter to connect to my router. The router registers that the IP 192.168.0.3 has connected (thats the IP assigned to the adapter) however even when trying to ping the router (192.168.0.1), I get no response.

icmp request from an ip that is in the same network as one of the local interfaces is not responded to, if the ping request is received via an interface in a different network. Is this some security feature?
Consider the below network
x.1|RTR1|-y.1---------y.2-|RTR2|-z.2------z.3-|LNX|-x.3
RTR - Router
x.1 -> 192.168.x.1
LNX - Linux machine

I cannot get either sendmail or postfix to send a 220 response, nor respond with details. See below for sample telnet output. Details: I have a server that requires email, but only for light use. I'm definitely not an expert, but I have set up a sendmail configuration on a previous server. I tried to configure sendmail first and then postfix later, when I couldn't get sendmail working. I'm not sure exactly what the problem is, but I have a feeling the following might yield some important information. Note: this is the result for Postfix, but virtually the same thing happened with sendmail, too. That is, initially the telnet connection would close immediately. Afterwords, I could connect a second time but then it never responded with a 220 banner nor any 250's.

I have been able (with some hair pulling and gnashing of teeth) to print from outside the LAN to the printer connected via USB to the desktop computer at home, until the last upgrade. The laptop will forst say the printer may not be connected, but eventually (usually) after a while says the job was sent to the printer. The log files on the desktop - serving as the printer server have an error message in cups/error_log that I am not familiar with, and don't believe I have seen before. I am sure if I could decipher that error and figure out how to change the behavior to get rid of it, it would once again work. Printing from within the LAN is a no-brainer as it has been for the last several releases. The error that I get when trying to print outside the LAN (via the internet) is:
cupsdAcceptClient: 12 from <WAN IP>:631 (IPv4) Unable to encrypt connection from <WAN IP> - GnuTLS internal error. I am missing something as far as authentication from the laptop to the desktop. how to fix it.

I was also having a problem with the Shutdown / Reboot sequence taking ages due to using WiFi, WPA2 and mounting SMB shares. I wasted about 4 hours digging around before I finally realised that the solution involved Upstart. 1. Open a terminal and enter:
Code: sudo gedit /etc/init/network-manager.conf 2. Just below the description line add the following:
Code:
pre-stop script
/etc/init.d/umountnfs.sh
end script
3. Save the script and attempt a restart. I don't know if this will work for everyone, or even what version of Upstart you need for it to work, but it cuts my shutdown time from about 2 mins to about 30 seconds.
Note: This has been working for me about 90% of the time. Occasionally though I see that the script ends prematurely due to the TERM signal and I end up with the 2 minute wait again. I've added the following to the /etc/init/network-manager.conf file:

I'm a little stumped on this one so I reaching out to see if anyone here has any idea. I just changed my ISP to Surewest as they're doing fiber straight to the house in my area so I have 8Mbps up and down.
I have my linux box running openssh and I have no problems SSHing into it from my remote laptop at work. I use putty to connect to it and create a tunnel so I can configure my firefox to use it as a SOCKS proxy. The problem is my response time for page loads in firefox is atrocious now. It'll take over a minute to load yahoo.com. The only real differences in my setup now are my ISP and router hardware at home. Previously, I was using the firewall that was built into my AT&T Uverse gateway. Now, I'm using my old Linksys WRT54G v5.0 router with the latest firmware. My linux box is wired directly into it with ethernet. When I run the speed tests from that box I get my correct speeds of 8Mbps up and down with <15ms ping. From what I can tell, all of my router settings are correct.

So I just changed my network card settings recently, and I'm now getting no response when I ping the broadcast address for them... the cards are all connected through a switch with IP addresses 192.168.0.x, broadcast 192.168.0.255... ifconfig on all of them shows UP BROADCAST RUNNING MULTICAST, but nobody responds to a broadcast packet. Any thoughts?
EDIT: Pinging each machine individually works fine.
