Ubuntu :: Cisco - Firefox - HTTP Post ?

Aug 7, 2010

I am using the following software stack:Linux version 2.6.32-21-generic (buildd@yellow) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) #32-Ubuntu SMP Fri Apr 16 08:09:38 UTC 2010 (Ubuntu 2.6.32-21.32-generic (Kubuntu) cisco anyconnect vpn client 2.3.2016, Mozilla Firefox 3.6.8

The problem I have is that once I join my company vpn, I have full access to corporate services confluence, jira, servers, etc. However when I use firefox to try and resolve a jira and post a body of text the connection timesout.

If i use any other browser it works fine, if slow, if i transition workflows it works fine, and if i use windows and firefox with the same cisco client it works fine.

This appears to be a specific issue with Firefox. I have noticed that in general firefox is slower on ubuntu than on any other platform.

Software :: Firefox And Http Post ?

Sep 10, 2010

There are a few web databases (also including my own php-based pdf manipulator), where I need to fill a html form, and upload file attachments.

About one year ago, these sites stopped to work correctly, when using Firefox (but they work from Internet Explorer). The problem concerns file upload.
Other users here also experienced this, and no firefox update corrected the problem in the past year (I am using Firefox 3.6.9 now, and the problem is still there).

When debugging my pdf creator, I found that the attachment-type of any file upload made by firefox is "text/html", irrespectively of what is the type of the uploaded file. Whilst files uploaded by IE have the correct attachment-type.

General :: Using Curl And WGet To Send HTTP Post

Oct 11, 2010

I would like to find out how I would use both curl and wget to sent an http post to get the hostnames of a few servers. I know am not even given any work of anything I have done, but the reason is that I am really lost, and I do not even know how to start it.

Server :: Lighttpd - Slow HTTP POST Attack

Jan 31, 2011


I ran across the above article, which described a DoS attack in which requests are sent very slowly to the Web server. I'm running lighttpd 1.4.28 on a Gentoo Linux server, and I'm wondering if there is anything I could do in preparation to defend against such an attack.

A bug report [url] seems to indicate that there was a patch in place already against this sort of attack, but I wanted to be sure that was the same thing and if there was anything else I needed to do.

Ubuntu Networking :: Cannot POST Http - Unable To Send Mail Via Squirrelmail

Nov 23, 2010

I have a really weird (but consistent) problem with my Kubuntu 10.10 install: I cannot post some HTTP forms.

First off, this is a client PC problem. My squirrelmail on the server works fine. I just use squirrelmail 1.4.17 to troubleshoot the ubuntu desktop problem

I used an old (07.04) Ubuntu install which worked fine. Then I wiped the disk and installed Kubuntu 10.10 on the same hardware. Everything works but **some** HTTP post does not work (I can log in but not send mail or save draft). I noticed I cannot log in to Yahoo, for example.

My webhosting account can display the apache access_log. When I hit the <Send> button the POST request never arrives to the web server.

I use a router (Dlink DL-604) behind a DSL modem and ooma box. There is a Windows 7 PC and a Kubuntu PC connected to the router. I can use squirrelmail just fine from the Windows PC.

I tried several steps:
- reinstalled Kubuntu
- installed Firefox and Chromium (on top of reconq)
- ran from a CD on my other (Windows 7) PC
- installed Wireshark and compared the traffic (but was unable to pinpoint a problem)

The result was the same: the <Send> button just keeps waiting; the POST request never makes it to the web server.

This sounds (and is) scary and suspect. The fact that the "demo" Kubuntu install (from the CD on my other Windows PC) using the reconq exhibits the same problem on a totally different hardware leads me to believe this may be related to Kubuntu. For example, I had to type this very message on the Windows PC as I could not post it on the forum from my Kubuntu box.

Ubuntu Networking :: HTTP POST File Uploads On PCs - Getting 500 Internal Server Error Message

Sep 23, 2010

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.

Software :: CURL Post Data Command From Shell - HTTP Error Code 408

Jan 29, 2011

I am trying to connect to the web interface found at [URL] using curl. This first requires login information to be entered at [URL], but I am having an issue with the login process. I am trying to submit the following form via POST:

<form action="j_security_check" method="post" id="login_form" name="login_form">
<center> <table style="background: #cac1cf;FONT-SIZE: 12px;">
<tr> <td align="center" colspan="2">Please enter your username and password:</td>
</tr> <tr> <td align="right">Username</td>
<td> <input name="j_username" style="width: 250px" id="j_username" type="text"/> </td>
</tr> <tr>
<td align="right">Password</td>
<td> <input style="width: 250px" name="j_password" id="j_password" type="password"/> </td>
</tr> <tr> <td colspan="2" align="center">
<input value="Enter" name="enter" type="submit"/>
<input value="Clear" name="Clear" type="reset"/>
</td> </tr> </table> </center> </form>
The command that I am using for this is the following:

curl -c cookies -b cookies -L -d "j_username=user%40domain.com&j_password=pass" [URL]
The command is properly formatted as far as I can tell. I tested it with another website using a similar authentication scheme using different POST variables specific to the form and it worked fine.

When I run the above command with the -v tag, it reveals this:
* Connected to lcl.uniroma1.it ( port 80 (#0)
> POST /sso/j_security_check HTTP/1.1
> User-Agent: curl/7.21.0 (i686-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/ libidn/1.18

> Accept: */*

} [data not shown]
< HTTP/1.1 408 The time allowed for the login process has been exceeded. If you wish to continue you must either click back twice and re-click the link you requested or close and re-open your browser

Closing connection #0

I cannot tell why the login timeout is expired when I try to do this, and my investigation toward this end has been fruitless. I saw a brief snippet on Google that vaguely suggested that the underscores in the domain name were at fault, but replacing these with their encoded counterparts did nothing to resolve the issue (that, and underscores should be fine when sent unencoded according to the standards). I have extensively perused the man pages and have come up with nothing to adequately explain this behavior. I also talked to a friend who has worked with curl in his line of work, but he mostly has experience in the context of PHP and has not dealt with this issue before. I am running GNU/Linux 2.6.35-22-generic-pae.

Ubuntu Networking :: Unable To Access Http:// In Firefox 3.6.18?

Aug 2, 2011

In ubuntu 10.04 LTS I am currently unable to access the location I have accessed it earlier. This is necessary for modem configuration. I am at a loss why this is inaccessible at present. Can anybody please advise what to do? I am configuring firewall but I doubt if that has anything to do with my problem. Or in case this may be due to faulty firewall configuration, please indicate denial of possible service/program which may cause this. Also ping reports 100% packet loss.

Fedora :: Try To Go Back To Add The Bug Report To This Post, Firefox Crashes, Every Single Time?

I'm running F 13 and today's updates included updates to Xorg, so I logged out and back in to let them take effect. Ever since then, Firefox has been repeatedly crashing, especially on certain sites. I managed to get the crash reporting tool to report it to Bugzilla, but when I try to go back to add the bug report to this post, Firefox crashes, every single time. Has anybody else found this? If somebody can get to bugzilla.redhat.com and find the report (The email address I use there is joe@zeff.us if it helps.)

Fedora :: Open Firefox - Get Really Strange HTTP And HTTPS Connections Showing Up In Firestarter

Oct 22, 2009

I've noticed that when I open firefox I get really strange HTTP and HTTPS connections showing up in firestarter (which as I understand it is just a GUI for IPtables). They connect to various bits of a site listed as 1e100.net (when you use "lookup hostnames") such as wy-in-f18.1e100.net, they stay connected all the time as far as I can see unless I close firefox. I've heard people say they are connected to Google, but I can close all tabs after loging out of google and still see them... it's very odd.

Ubuntu Servers :: Nagios On 10.04 Server Using Apt-get - HTTP WARNING: HTTP/1.1 404 Not Found

Aug 4, 2010

I installed Nagios on my Ubuntu 10.04 server using apt-get and when I accessed the web console, everything was OK. I made some changes to apache (creating some new virtual sites) and since then Nagios gives me a warning message for HTTP with the message, HTTP WARNING: HTTP/1.1 404 Not Found. The sites that I created are working perfectly. I noticed that the attemps are 4/4. Does this need to be reset or does Nagios automatically reset that once it detects the issue is resolved?

Networking :: Craft A Valid Http/1.1 Request For Getting Http Headers (not The Html File Itself)

Sep 27, 2010

Using netcat, nc(1), craft a valid http/1.1 request for getting http headers (not the html file itself!) for the main index page of www dot aalto dot fi. What request method did you use? Which headers did you need to send to the server? What was the status code for the request? Which headers did the server return? Explain the purpose of each header.

nc -v www dot aalto dot fi 8080
host: www dot aalto dot fi
And it returns:
200 OK
Content-Length: 858
Content-Type: text/html
Last-Modified: Thu, 02 Sep 2010 12:46:01 GMT

I really don't know what does it mean. Question 2: Using netcat, nc(1), start a bogus web server listening on the loopback interface port 8080. Verify with netstat(, that the server really is listening where it should be. Direct your browser to the bogus server and capture the User-Agent: header "Direct your browser to the bogus server and capture the User-Agent: header" I don't understand this question.

When I click on "submit" to post a thread, the page will just say "loading..." and nothing happens for a really long time. Does anyone know what is up?

Ubuntu :: Cannot Uninstall Cisco AnyConnect VPN Client

Mar 4, 2010

In order to gain access to my university network remotely I was asked to open a website that would act as a gateway. Upon opening the site I was asked to run a Java application, which installed a Cisco AnyConnect VPN client on the system. However, now I do not need this, but I cannot find a way to uninstall it. It does not appear in the Synaptic Manager or the the ubuntu Software centre, so I cannot find the package to uninstall it. The software does appear in the 'Internet' section in the Application drop down menu and runs without the need of Firefox. I read the Cisco release notes but I could not find a way to uninstall the software.

If I execute ls -la => connection stalls. I think it stalls every time it is supposed to return more content (top, ls /etc).

If I do scp from my end to server => works. If I do scp from server to my end => connection stalls.
