Squid proxy server (redhat) latency issues?

I need to deploy a proxy server on a network servicing about 200 machines.
If I virtualize redhat Linux to use squid, will the latency be too much? Bear in mind that the underlying OS and hardware (server 2008 on RAID-5 and 2GB of RAM) must also act as a WDS server. If it weren't for the necessity of WDS I would make
the whole machine a RHL box.
My boss thinks that there will be too much latency... I on the other hand don't have the experience to know or the time to build a prototype for testing it.

I would doubt that the latency will be an issue. Almost every kind of workload is being virtualized these days. Hypervisors in general, and Hyper-V in particular, offer synthetic devices such as NICs and storage controllers along with custom device
devices for those synthetic devices specifically so that performance and latency can get pretty close to what you would have with physical devices. Virtual appliances for various network functions such as proxies, firewall, and load balancers, have been
created specifically to run in virtual environments, and they are achieving the necessary performance and latency. I'm sure there might be specific situations that are particularly sensitive to latency and that could be a problem running virtual, but
all the mainstream scenarios are pretty much OK.

Squid proxy server request

sir
I installed squid proxy in our environment for making internet access fast.It works fine when browsing internet. But when we access the our internal webserver\
located in another location it provides the following error message
unable to determine ip address for host
The dnsserver returned:
Name Error: The domain name does not exist
the ip address of requested url is 10.0.0.23. We are using vpn to connect to that network.
please suggest solution for this problem

You will need to specify a DNS server that is the authority for your local network domain, which is also configured to forward your non-authoritative (public internet) requests to another or public DNS servers. When specifying multiple DNS servers, keep in mind that any response from the DNS server, unknown or successful, will satisfy the request and other DNS servers in your list will not be queried. Some implementations may allow you to attach DNS servers to DNS searchlists. If you have a small local network, it might be the easiest to add your local hosts to the /etc/hosts file. Depending on your network security you may also have to look into possible problems of denied requests to DNS servers outside your network. Is there a special reason why are you using a proxy?

Latency issue in Desktop Sharing

We are planning to develop a conferencing solution using LCCS. I am trying to evaluate the screen/desktop-sharing application. I am experiencing 5-10 seconds latency during the transfer of the screen data to the other end.
I am using the demo application(ScreenShareSubscriber and ScreenSharePublisher), provided in the SDK.
Some more details:
- Current OS is Windows 7 (32 bit).
- I am behind a proxy.
- I am running the applications in India.
- Using Flex builder 4.6 with Flash player 11.1.
- Using the developer account to test the application.
Questions:
- Can the delay be reduced programatically? If yes, then how?
- The final solution may be used by people distributed across the globe. Is there a possibility that, the latency is affected by your location?
- If the above is true, does Adobe provide cloud services (for commercial applications) that are distributed in different location, to reduce the latency?
- Can proxy server be an issue? We have port 443 open on the proxy server for TSL connections.
- If the above is true, then how can we avoid the issue? The final application may be used in a corporate network and we cannot ask everyone to change their network settings to connect LCCS services.
I have checked some posts on the forum, which say that, the performance is faster on Macs. We are currently not targetting the Mac platform.
Thanks,
Subrat

Hi,
Please double check the following firewall port between two subnets.
Front End Servers-Lync Server Application Sharing service 5065 TCP used for incoming SIP listening requests for application sharing.
Front End Servers-Lync Server Application Sharing service 49152-65535 TCP Media port range used for application sharing.
Clients 1024-65535* TCP Application sharing.
If the issue persists, you can use the Lync server logging tool on FE server to test the process of desktop sharing.
Here is the link of using the Lync logging tool:

Safari 3.x (Leopard) and Web Proxy Server Problems:

I have a Squid proxy server running on Linux. Users web traffic is directed through it via WPAD server which hosts a simple PAC file. The PAC files is very clean and small. It basically points all external (Internet) web traffic to our Proxy server. All of our Windows, Linux and Tiger clients work fine. However, Leopard (Safari 3.x) doesn't work quite right. Here's what happens:
Mac user logs into a Leopard 10.5 Mac. User launches Safari and tries to go to an external (Internet) site. The WPAD server is contacted and the Mac User is prompted to authenticate to the Proxy server. This is totally normal behavior thus far. Then, however, every few minutes the Leopard Mac user will be prompted to authenticate again (sometimes 2 or 3 times in a row!). Firefox 2.0.x, when configured to use the WPAD/PAC server and Proxy server, works fine in Leopard. Only Safari 3 in Leopard is having the problem.
All the Macs (Tiger and Leopard) are configured to use the Proxy server via OS X's Network Pref Pane (using the "Automatic Proxy Configuaration"). Reminder: Tiger works fine (even with the Safari betas), but Leopard's doesnt not.
I have attached our PAC file inline below (some things edited for privacy):
// SIMR automatic configuration for Mozilla and friends
// $Id: wpad.dat,v 1.8 2005/12/14 20:18:23 dct Exp $
// Edit carefully, since many may be relying on this...
function FindProxyForURL(url, host) {
// Bypass the proxy for internal addresses
if (!url.match("http:")
|| url.match("http://127.0.")
|| url.match("http://10.")
|| url.match("http://192.168.")
|| isPlainHostName(host)
return "DIRECT";
// These are exceptions given in the IE config for Windows.
if (host == "www.ncbi.nlm.nih.gov"
|| host == "chabry.caltech.edu"
|| host == "flybase.bio.indiana.edu"
|| host == "www.fedex.com"
|| host == "domain.org"
return "DIRECT";
return "PROXY <proxy server>:8080";
}

I think I have a similar problem. I am a Mac connecting to an otherwise all PC school network.
A new location with all correct proxies has been set up. However, Safari always crashes on first attempt to negotiate its way through our server to the internet. Internet explorer gets through because in its preferences it is possible to include the name of the school domain as well as my user name and password.
We have been unable to find any way of including the domain name into Location in Network or into Safari.
However, once Internet Explorer has negotiated with the server I can launch Safari and it works as normal.
Safari/Network seems to lack this option of including a domain name that my PC server requires.
Make sense to anyone?
Worth mentioning that my copy of Internet Explorer (5.2) often crashes, but usually it has done its job by then. I quite like the concept of Internet Explorer sacrificing itself to clear a path for Safari.

Messages with Server 3.1.2 behind a proxy server

Help ...
I am familiar with earlier iterations of the Mac OS X server software and set up a largish 16TB system in a UK hospital before I retired. I am now working for a charity in a remote location and testing the latest version running on a recycled MacBook Pro to see if it could be used in earnest to provide local services to support the volunteer community here. Access to the internet is very slow and heavily restricted by a Squid proxy server and I find the lack of a comprehensive OS X Server manual frustrating at times (if there is one please point me to it!).
I have File Sharing running fine, but I am struggling to find the workable settings for a cross platform local messaging service. I am trying AIM initially, but whatever settings at the user end I select I keep getting either 'server refusing connections' or 'unidentified AIM socket error' messages.
Any assistance would be really appreciated ... especially as this is my foray into the world of Messages!
Thanks in anticipation,
Ian
Test system: Server: MacBook Pro running Server 3.1.2 on Mac OS X 10.9.4 Client: MacBook Air running Mac OS X 10.9.4

Since posting this I have been able to download more information and also search the ASC threads - and see I should be using Jabber.
So - I may still need some advice but I am working towards the solution ... hopefully!

Mail Under Squid Proxy

I'm under a corporate proxy (squid) that only has port 80, and 443 available. However, it seems that mac's mail app cannot connect through only these ports.
Is there a way to make Mail connect through 80 or 443? I cannot make a ticket for other ports to be opened as they would only say to browse email through browsers.

If your Squid proxy server is setup only to do ports 80 and 443 it is only doing http and https protocols. If your trying to access an IMAP account you need ports 993 and/or 143 to be proxied. However this will mean you need Squid to be configured to also support that which is via a different type of proxy called a SOCKS proxy. Squid can do both SOCKS and http/https parodying at the same time.
If your connecting to an Microsoft Exchange Web Services (EWS) server then this as its name suggests it uses standard web i.e. http/https protocols and will work with ports 80/443.
It sounds therefore that you are trying to connect to an IMAP server, unless SOCKS is setup then you will be blocked.
If you are trying to access a corporate mail server then the IT department should set things up to enable this e.g. by setting up a SOCKS proxy server. If you are trying to access a personal email account e.g. Google Gmail then you are going to have to use webmail. Personally for personal email I far prefer using a webmail interface as then my personal emails are not stored on the companies computers.
If you are trying to access a corporate Microsoft Exchange server then it is possible EWS has been disabled as Windows clients do not use this protocol, again the IT department should ensure that they provide the services needed to support Macs if Macs are being supplied to users. If the company is providing Macs to users and the IT department is failing to set things up to allow those Macs to connect then the IT department is failing in their job and the person responsible should be replaced with someone better up to the job.

Outlook 2011 Connection Issue with Proxy Server after 10.8 Upgrade

Hello,
After upgrading my MBA to 10.8, my MS Outlook (Outlook Mac 2011) mail connection does not work for an exchange based mail account where a VPN/proxy server combination is involved. This was not an issue at all under 10.7. What's interesting is that it's not an issue with MS Outlook 2010 on my Parallels VM either under 10.8. There are no internet connectivity issues, I am able to connect to the internet using Safari and other browsers. Any help would be appreciated.
Thanks,
Manish

I was having a similar problem using Outlook 2011 running under Mountain Lion (10.8.2) on an MacBook Pro. When at work, behind our proxy server, I could not get Outlook to connect to a client's public Exchange server, but this worked fine without changing any settings when I was connected to our DMZ network or at home (no proxy server in these cases). My MacBook was configured to use "Auto Proxy Configuration", and Safari worked fine in all three locations (as did Apple mail)
Today, the Microsoft Office auto-updater downloaded an update, and since it was installed, the problem has been fixed and I've been able to connect to our client's external Exchange server event when behind our local proxy server (Outlook now reports that the latest installed update is 14.2.5)

This error message shows that its not able to get the socket connection to the server.Can anyone tell me the reason of it.
If you need any more info do let me know.

Somendra

First of all, is there a reason why you are using jRockit?
Since the issue appeared after upgrading the windows, the issue would potentially be in the interaction between JVM and OS.
Also, there were some issues related to memory leak that were fixed in AS 8.2.
May be you should try with a Sun JVM and AS 8.2.

ACE SSL initiation via Proxy server (squid)

Hi,
is it possible to configure ACE with SSL initiation if the connection goes via http/https proxy (squid) ?
I mean local host is requesting http://xyz.com, ACE doing SSL and requesting https://xyz.com, not directly but via http/https proxy server (squid).
Thanks

Hi Ryszard,
Yes, ACE can initiate SSL traffic and maintain SSL connection. So in SSL initiation ACE will act as a CLIENT receiving clear text HTTP traffic at the front end and sending traffic encrypted over the backend.
For more details please visit the below link and let me know if you have any questions.

SQUID Proxy cache issue in front of Oracle webcache & Oracle Portal 10g

We are having issue with our site designed on oracle portal front ended by webcache and squid proxy. Current our squid proxy is configure to cache site data which is causing the problem.
The problem is, we have website in multiple language (china english and china chinese), when you navigate the site in both the languages and once the navigation pages are cached in our squid proxy cache, the users see the cached data from the proxy cache(ie. they will see china chinese when navigating china english site and vice versa). Following are my questions?
1. I was wondering anyone of you had similar issues and what did you do to resolve it?
2. What proxy were you using, name, version etc would be helpful?
3. Did you have similar issues with Other proxys out there? besides squid? what was the fix?
Your response is appreciated.
Thanks,

Issue with binary attribute types through Directory Proxy Server 6.3.1

I'm having problems with DPS 6.3.1.1 on Solaris 10 with binary attribute types. From most LDAP servers, requesting an attribute such as userCertificate would return userCertificate;binary without any issues. However, DPS seems to consider these two separate attributes. In order to see userCertificate;binary, I have to ask for it in that exact format. This obviously is causing trouble for many clients as they shouldn't care about the binary type as it's the same attribute.
I've tried to correct this with a virtual data transformation (dpconf add-virtual-transformation 'PKI Tree' read add-attr-value userCertificate \${userCertificate\;binary}) but the end results are the same. Any ideas on how I can correct this one?
Thanks in advance.

Firewall/Proxy Server Issue

I'm testing a new Flex/CF app. From my location it runs well
on the production server. But from another location that is behind
a Symantec firewall/proxy server, it runs unusably slowly. I'm
using Flex remote object calls (Flash remoting) to communicate with
CF. I don't know if the problem is related to that or simply
something to do with Flash Player. Has anyone experienced this
problem? I'm not a network administrator and am not familiar with
Symantec firewalls so I'm not sure what to ask their network admin
to try. Any advice would be greatly appreciated. Thanks.

Did you add a new library in the project to include weblogic.jar from the WebLogic 6.1?
What kind of a client is it?
You can also try using the setting in the menu
Tools | Preferences | Web Browser/Proxy
to enable disable the proxy.

Running windows 7 firefox refuses to come up, proxy server is refusing connections network adminiastrater says proxy servers are correct and is issue with firefox what do I do/ do

I start up firefox and it says the proxy server is refusing connection. It is configured to use a proxy server that is refusing connections. To check the proxy servers and ask network administrater to make sure proxy server is correct They say the proxy server is correct and it is a firefox problem. So what to I do now?

Make sure that the Firefox connection settings are the same as in IE.
You can find the connection settings in "Tools > Options > Advanced : Network : Connection"
If you do not need to use a proxy to connect to internet then select No Proxy
In Firefox 3.6.4 and later the default connection settings have been changed to "Use the system proxy settings".
You can compare them with the IE settings in the Internet Options (Control Panel).
Control Panel > Internet Options > Connections: LAN Settings

Issue with using Sun Java Proxy Server

We are trying to access the WebService using the Sun Proxy Server.
When I access the WebService through proxy ,I find the error message in proxy error log as

and the access log is as follows:
POST http://localhost:1080/yodsoap/services/CobrandLogin HTTP/1.1" 400 147
But when i see the WebServer access log for the same WebService POST /yodsoap/services/CobrandLogin HTTP/1.1" 200 1783 "-" "Axis/1.1RC1"
This case is happening when the request is compressed for the webservice. and the request headers are as follows:

So ,we found out that if we dont use the proxy server,then the WebService is working properly,but if we start using the proxy server,we are encountering HTTP400 error.
Any ideas will help out to solve this problem..???
Thankz in advance.
