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.

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.

I have configured Sendmail client to send mail to outside network ( Within local domain ), but i am unable to send any mail as i am getting the following error,
[root@cclx10 mail]# cat test |sendmail -v abhilash-o.padmanabhan@hp.com
abhilash-o.padmanabhan@hp.com... Connecting to [127.0.0.1] via relay...
abhilash-o.padmanabhan@hp.com... Deferred: Connection refused by [127.0.0.1]
I have the following configuration in my "/etc/sendmail.cf" file
# SMTP daemon options
O DaemonPortOptions=Port=smtp,Addr=15.146.237.113, Name=MTA
And netstat is showing that sendmail is listening on Port 25 on the IP address which is mentioned.
[root@cclx10 mail]# netstat -an |grep 25

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.

the sendmail packages on my f15 server were updated from 8.14.4-20 to 8.14.5-1 yesterday. since then, every attempt to send mail via a smart relay have failed with :
Jun 25 14:05:10 server sendmail[23512]: p5PD59jr023512: from=root, size=208, class=0, nrcpts=1, msgid=<201106251305.p5PD59jr023512@server.{fromdom ain}>, relay=root@localhost
Jun 25 14:05:10 server sendmail[23513]: p5PD5A8l023513: from=<root@server.{fromdomain}>, size=480,
[code]....
i've tried using various different smtp relays and they all now throw the same error. without going through all my sendmail config, i have the following entries in /etc/mail/sendmail.mc :
define(`SMART_HOST', `{smtp server}')dnl
FEATURE(`authinfo', `hash /etc/mail/authinfo')dnl
and the /etc/mail/authinfo file contains :
AuthInfo:{incoming mail server} "U:{user}" "P:{password}"

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 2.6.32.11+drm33.2) (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.

My company email server has been working flawlessly for the last 5+ years. Recently, one of our clients put their email server behind a firewall (an assumption on my part; details below). Ever since, email sent from within the company (192.168.xxx.xxx internal address; all computers and server is behind a NAT firewall [Netgear FVX538]) is either being sent to the client after some delay (if email is sent using Outlook) or is being deferred until the messages expire (Thunderbird, Squirrelmail, etc.). Email sent to the client from anywhere outside the company (using Thunderbird, Outlook or any other email client) is also delivered without any problems (usually after a short delay).
All other emails to the World are being sent without any problems at all (both inside and outside the company; using any email client or webmail). I did contact the client's postmaster, but the client, being a large government agency, will probably not address the problem (if it is on their side) anytime soon. I am not sure if I can do anything from my end to solve the problem. Ever since the problem with the client began, I added two statements to the postfix configuration file (smtp_pix_workaround_delay_time = 20s and smtp_pix_workaround_threshold_time = 0s); this seemed to a bit - it reduced the delay for emails sent via Outlook to a few minutes (as opposed to 30+ minutes); emails sent using Thunderbird/webmail are still being deferred.
Server details: Dual quad-core processor machine, 32 GB RAM, dual 1 gbps network, running Fedora 14 (64-bit; loosely modeled along the lines of Perfect Server (with ISPConfig2) as described on the howtoforge website). Running Postfix (v. 2.7.1), Dovecot (v. 2.0.9).
Postfix details:
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
body_checks = regexp:/etc/postfix/mbl-body-deny
broken_sasl_auth_clients = yes
command_directory = /usr/sbin
[code]....
I emailed the client's postmaster suggesting they disable smtp fixup. But still, what bothers me now is that Outlook works (both within and outside the company) while Thunderbird, webmail, etc. (used by ~90% of the users) do not. In addition, all email clients from outside the company can send email (authenticated via the company server) to the client without any problems. Is there anything I can do on my end to make non-Outlook clients work within the company (webmail is hosted on the company server; so, it would have an internal address as well)?

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.

I have software with a newsletter system - but because I have 16 clients per server they are currently all sending emails from the same (eth0) IP address DESPITE having a DEDICATED ip address per client account for their WEB address. If one spams (or gets spam complaints) then they all suffer - and I'd love to send their email via their unique IP address to stop this problem and to make the IP match their domain which has to be better at getting through spam filters anyway I'd have thought...

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.
