AleME proxy problems

 [1/7] from: ale870:gmai:l at: 22-Jun-2006 8:15


Hello, I noticed I cannot use Alems using proxy. Inside my company we have a proxy and firewall to access to internet. I can use browser web, but I cannot use AltMe. Does altme use port 80?

Altme doesn't use port 80, and does not work behind squid. On 6/22/06, Alessandro Manotti <ale870-gmail.com> wrote:

Guys, I am not sure, really. The port 5400 does not have anything in common with proxy imo. Proxy is proxy, and rebol supports it. You can set your proxy port, often 1080 or 3128, or ... whatever. The port 5400 requirement is there to look-up the world. It simply returns you domain or IP adress of the server, particular world runs on. I don't understand such a move, it can be done via web, cgi imo. I can see it as SafeWorld's marketing protection, so that it is not used by everyone in corporate sphere? :-) Well, maybe I am wrong, but you are on the same boat as me - our admins will not open FW port for me to use AltME, they are strict and paranoid about that. AltME is not knows as IRC and ICQ, which are enabled to use in our company. So, at my work I have notebook with GPRS connection, fast enough for AltME .... Petr

No Petr, proxy is not a proxy... Ok... I'll be more clear... A server is waiting for client coming from a specific port (e.g.: HTTP servers usually expect the clients (brwser web) on port 80; FTP server on port 21; etc...); Client browser send the request to the server to a specific port. CLient browser "allocates" a client port that is different from server port. Look at this: FireFox browser -------> server apache (port 3300) (port 80) It means, if I want to use Firefox to reach server apache I must walk within port 80. My proxy should let me use such port: FireFox browser -------> PROXY ------------> server apache (port 3300) (enabled: 80 (port 80) (disabled:5400 Only the requests direct to server port 80 can continue their travel, the other ones cannot. Proxy setup used in Altme is used since a proxy can create a map from incoming and outgoing connections: IN:8080 ---> OUT:80 (typical configuration) On 6/22/06, Petr Krenzelok <petr.krenzelok-trz.cz> wrote:

Hi Alessandro, On Thursday, June 22, 2006, 9:53:22 AM, you wrote: AM> FireFox browser -------> PROXY ------------> server apache AM> (port 3300) (enabled: 80 (port 80) AM> (disabled:5400 If you put it this way, then it's a firewall, not a proxy. (NAT is somewhat in between, although it is usually referred to as proxy .) What Petr was referring to is - to make the HTTP example - something like Squid. In this scenario the client connects to the proxy which in turn connects to the server; all three must be using the same protocol, or at least understand each other's protocol. But Petr is wrong in that AltMe can work with all proxies, since AltMe does not use HTTP or any other standard protocol that a proxy could understand. (It can work with proxies that allow plain TCP connections using the SOCKS protocol, though.) So, if you are under a firewall, that only allows certain ports out, the only way is to ask the admins to enable AltMe's port. (It would be nice if the AltMe server would also listen on additional common ports, like 80 or so; however this can confuse many proxies, firewalls and IDS because it would be using a custom protocol on the HTTP port.) If you need to pass thru a HTTP proxy then you are completely out of luck, because AltMe does not use HTTP. If you are under a SOCKS proxy then AltMe should work.
