CentOS 5 :: Unable To Use Outlook/thunderbird Behind Squid Proxy
Jan 7, 2010
I am not able to use outlook or any other email client on my computer(to access gmail account) I am also not able to forward port to my computer for a bit torrent client
I can access the internet using proxy settings
I have just installed CentOS 5 as a server with 2 NIC's for my home network.
My set up is something like this
adsl wireless router(static ip from ISP) - (192.168.0.1/24) Cent os server (10.1.1.1/8) - switch/hub - clients(windows XP/Vista,Linux)
the linux server acts as a Web Server,DHCP and Squid proxy server
Will installing an email server resolve my problem?
I am using FEDORA 11 and Squid 3. Squid configured and working perfectly but some Win XP users unable to access their mails through outlook express. can anybody guide me what should i do to enable pop/smtp ports via through nating / MASQUERADE etc..
I would like to ask some help and tutorial for setting up and how to configure squid proxy server in my (Home PC Server). I am a newbie in Linux Centos. I already installed in my system the CentOS 5.5 . Now, I want to configure it as my internet server, all of my 4 system running in Windows including the laptop I want to connect through my CentOS pc with username authentication. I assign all IP address by static. see tthe attachement in my set up. [url] I just want to know what I need to change and add in my squid config file. And how can I configure properly my CentOS with 2 LAN card as internet server.
I've set up Ubuntu 9.04 (desktop) at home in a lab environment (workgroup rather than domain) and have configured Squid. Everything works fine but, when I took it to the next level and made the proxy transparent, my problems began. I can still access sites (having pointed the XP Pro client to the squid box as the DG) and the sites are logged in /var/log/squid/access.log but I am unable to use Outlook to access my SMTP and POP3. I guess that the setup is blocking ports 25 and 110 and I'll need to configure iptables to forward packets destined for these ports directly to the "real" DG, rather than the Squid box. Here's the set up:
A single NIC (eth0) on 172.19.0.250 / 16 (static) ADSL router ("real" DG) on 172.19.0.1 I executed iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3128 My squid.conf:
Code: acl all src all acl manager proto cache_object acl localhost src 127.0.0.1/32 acl to_localhost dst 127.0.0.0/8 acl localnet src 10.0.0.0/8# RFC1918 possible internal network acl localnet src 172.16.0.0/12# RFC1918 possible internal network acl mynet src 172.19.0.0/16 [Code]....
i have a proxy server up and running but one server using port 8181 cannot be accessed.how i can open that port!...i tried adding it in the safe ports but it still isn't working...
today i encountered centos 5.5 final server with a squid configured to block facebook from 9am to 4pm. i have tried to follow up the steps but am stack where time restriction is done and there is no proxy configuration done in the browser. the ip address of the server is being used as the default gateway.
Here is my network diagram ADSL router----firewall--LAN inside the LAN my squid is running. currently all users are working with out proxy server. I installed the proxy server inside the LAN. now all users can access web browsing ,but no other ports are working , like POP3, smtp, then some other TCP port based applications are not working. My firewall ( juniper) is created and tested the rules to allow the POP3 and smtp and selected poprts which is working , but I redirected through squid proxy server the clients are not able to access. where do I have to create rules?
** in squid proxy( i already did in safe port list stillnot working) ** IP tables?
I'm trying to setup a Centos 5.6 Squid Proxy Server with Content Filtering & Antivirus Scanning Incoming HTTP Traffic from the Internet
I then proceeded to setup an configure the Proxy Server, i was able to test and confirm that Squid and Dansguardian Content Filter is working, however i dont know if Clamav is scanning HTTP traffic before it hits the client/server. Is there a way i can check if the Antivirus scanning is working.. is there some log file or real world test i can i can do to confirm that Clamav is scanning incoming traffic or even blocking potential viruses ??
Anyone who has squid proxy server with Clamav configured and its working can share there settings/setup with me and how they tested it ??
Currently my DHCP Server is working now what i want to have is auto detection of squid proxy in any browser but I still got an error in my dhcp server when I restart it.
My Config:
# DHCP configuration generated by Firestarter ddns-update-style interim; ignore client-updates;
I searched in forums but I couldnt solve my problem. I copy my pst files of outlook on windows then I completely remove windows and set up ubuntu. I made all my configuration on thunderbird. I can send and recieve mails but I could not import my old mails from outlook to thunderbird.
We recently upgraded to Microsoft Exchange 8.2.176.0 for our web mail. I've never had it setup for my desktop, I've always had to rely on a browser and access webmail. I'm trying to set it up on my Thunderbird 3 on Debian but it doesn't seem intuitive. I've also tried various ways in Evolution.
A client of mine has a 7.7G .pst file, every time I try and import it into outlook so I can import to Thunderbird, it breaks due to the size, as Outlook can't handle files bigger than 2G. Is there anyway I can import this file into Thunderbird without having to use Outlook?
I have an Outlook 2007 PST file that iam trying to import into Thunderbird/IceDove. Based on what google told i tried readpst, it gave me the following error
Code:
$readpst -o PSTfolder/ -r Outlook.pst
Opening PST file and indexes...unknown index structure. Could this be a new Outlook 2003 PST file? Error opening File I did have a look at outport, but it hasnt been updated since 2008(?) i doubt it would work with outlook 2007
i have a squid proxy on a centos 5.4 64 Bit machine. i can share internet on my other boxes hosting centos 32 bit and windows by entering the proxy server IP in the network proxy (centos) internet explorer (windows). but i cannot get mails on my thunderbird client behind the proxy even though i have included ports 110 and 25 in the squid. i v heard it cannot do it as squid is not imap proxy.
i want to setup squid proxy server at my home. my service provider has ISA server install on its machine. in windows as a client we have to enter proxy settings manually to IE and firefox. but now in squid where i have to define to use this proxy settings. and what about /etc/resolv.conf . my service provider's connection settings are stated as under.:
IP ADDR= 192.168.1.x subnet mask=255.255.255.0 Proxy= 192.168.1.1 port= 8080
I have to use squid proxy server on fedora14 to develop the application/ software based on the Proxy sever analysing and count number of user and downloaded file size... .My main problems are, I'm not able to configure the access.log file in "Common Logfile Format" and how to develop the application
we having more than 5000 users and will have 7 squid proxy servers with high end configuration upto 4gb ram n 320*5 HD in rhel4&5 most of them complaining that at peak hours their browsing speed is slow but we are having 1gbpgs link at peak hours i.e when established connections r flowing more than 550 browsing gets slow how to do fine tuning are squid is only responsible to access upto 600 connections
I'm trying to set up squid proxy as a replacement for a cgiproxy perl script.I would like to be able to hit it with a url, and have it pass everything back to the browser, something like URL... much the same way the cgiproxy script works.
This is my first time messing with squid, and I am completely lost. Does anyone have a link to some very detailed step by step instructions on how to do this?Can someone please tell me *which* kind of proxy I'm looking for? I see "interception proxy" or "transparent proxy" and a bunch of other terms thrown around in the docs, but nothing I have seen tells me which of those I'm actually looking for, or if what I'm trying to do is even possible with squid.
I need to setup a squid 3 proxy with https bumping. Unfortunately I'm not very familiar with squid and https in general.
I already perfomed the following steps:
1.) compile from source
Code: Select all./configure --with-openssl --enable-ssl-crtd make make install
2.) configuration (http) I used this guide: [URL]
3.) configuration (https) [URL]
The server is now working for http and https, but is the server secure, too? Is the default config already secure or do I need to configure additional security features? (e.g. things like cert validation, cert pinning, [dont know what's importend], ...)
I have 4 servers running squid/3.1.1 proxy server. Since the latest version I can no longer FTP. I have posted this problem in multiple places but have received almost no response. I've found several other post to this problem throughout the Internet which have also gone unanswered. So, once again, I thought I'd give it a try. As I said "I have 4 servers running the newest version of Squid". When I try to access an ftp, any ftp, I receive an error (check attached image). This was never a problem until just recently. Squid should work perfectly find with ftp, it is not a strictly http proxy.
I turned my firewall off just to make sure, still had the same issue. If I jump directly on the server itself with no proxy settings set in the browser it will work fine. As soon as I set the browser setting to access the Squid software I get the same error. I've included my squid config (which is unchanged from the default settings), maybe somebody better versed than myself can point out an obvious flaw. Everything else seem to work just fine, it's only FTP that's a problem.
I have a reverse proxy set up with squid. I'm going to try and explain what it's doing and I apologize for it being confusing, I'll do the best I can to describe my problem. First, it's for our phone system. We run a ShoreTel Voip system. The owner has decided he wants me to setup MCM (Mobile Call Manager), which from what I can see is an under developed, and almost impossible to get help with Shoretel software. But he's convinced he needs it for his Iphone. It's supposed to, in a nutshell, turn his Iphone into his work phone with all the advantages and doodads that come with it. Apparently, "they have an app for that". On the server side, I need to setup a reverse proxy back into the network on our phone server. Simple enough, I did this with squid. I used the following lines:
always_direct allow all It most definitely is allowing traffic back to the phone server, the problem is, it hands out my internal server address to the outside client. So for instance, if I connect to the outside routable address with my phone, it will immediately change the url to http://172.17.137.7 which is the inside nat address of my phone server. Which of course doesn't work, since I couldn't browse to that address from the outside. It does however work from the inside of the network, obviously because 172.17.137.7 is accessible from the inside.
I am trying to set up squid to make switching proxies easier. I have a laptop which I use at work and at home. At work, I need to connect to the internet via a authenticated proxy. At home, I connect directly to via mobile broadband. So I end up switching proxy settings twice daily, which is just irritating! To solve this I want to set up a system whereby I never have to worry about a proxy - my browser sees a direct internet connection which squid (on my computer) intercepts and forwards either to the mobile broadband connection or to the work proxy (along with the required authentication) depending on which is available. I've read various articles on how to do clever things with iptables and squid, but I don't understand enough of the networking jargon or concepts to know when I need to change to make it work in my situation, or if it is even possible.
I need to block some of my sites with SQUID Proxy. I added following lines to my SQUID configuration file but still the site remains unblocked.How to block it?
I have set up squid3 and dhcp server on my Ubuntu 10.04 box with IP address of 192.168.0.160. Single network card.Squid runs on port 3148. Everything works fine for the users provided that I set up the proxy details manually on each client pc.I want to set up the Squid to run as a transparent proxy and after reading around I have done the following.In the Squid3 conf file I have entered http_port 3148 transparent.Dropping to Root ( sudo -i )However the transparent proxy does not work and if I enter iptables -L I can see that the rule above has not been retained. The default rules in iptables only show up.
