Essentially all of the top, tier-2, tier-3, etc providers have some type of online network status web site. How well they use it to keep users of their network informed varies greatly. Abovenet - Web site with MRTG graphs, and copies of messages from their tech contact mailing list about problems, outages, and scheduled maintenance. AGIS - no more. Closed access to their network status web site years ago. AOL - I don't know, I haven't found anything on their public web site. AT&T - Network status web site with red, yellow, green city to city matrix. Outage portion of the web site is never updated. Worldnet only newsgroups frequently updated with detailed problem reports. C&W - Traffic web site (red, yellow, green), but I've noticed they seem to only have "green" dots on the front map. You have to dig to find the problem sites. Has an outage mailing list, but it never has any mail and even C&W employees seem unsure of its purpose. Exodus - BENGI web site with major trouble tickets available. Genuity/GTEI/BBN - customer only network status web site. "Finger" access to trouble tickets, including master tickets. Good proactive notification of customers of problems. Globalcenter - customer only web site. Mindspring - Mindspring has a public network status web site with current trouble tickets. PSI - used to have a detailed "finger" and web site network status page, starting last month I get an access denied message. SBC/PBI - Web site with current network status. Frequently updated and includes resolution or reason for outage. Sprint - Has a web site describing scheduled and emergency maintenance mailing lists. Scheduled maintenance mailing list has some messages, but I've never seen a message about an outage on the emergency maintenance list. UUNET - web site updated for some major outages. Says details will follow, but usually the entire web page is "refreshed" to all systems normal message every few hours whether or not the problem is fixed. Some customers reportly received mail messages about outages.

I have looked at it but it does not fit my needs at all. The system I'm developing (which _is_ based on qmail tho), has several advantages. Also, I don't need 'user-less' stuff, because all customers already have a hosting-account for FTP and shell. The big advantage is that users own and control their own mailinglists, popoboxes, forwards and all that and normally don't need _any_ intervention from us to get anything done. This also allows for easy quota-enforcing and accounting - all stuff from one customer is under 1 UID. With that user-less stuff, AFAICS the admin needs to do work for each popbox created. This ofcourse can be automated, but is still a centralized process. We are moving towards decentralization as far as possible while still keeping a grip.

Are you sure that you have only 1MB RAM, or is that a typo? Did you mean to say 1GB? > Roeland, you mentioned in your email about XTND XMIT, may I > know what is that ? It is the means where a client can send mail via the POP3 channel, rather than SMTP. Some clients can do this, if it is available. We have tested Netscape messenger and Eudora for this feature. There are some serious benefits to this, like being able to lock clients into a single POP host, forbidding them to see other SMTP hosts, or ANY SMTP hosts. Thus, keeping all email internal connections, internal. It is part of en extended POP specification that is part of the POP3 RFCs. Do a search through the IETF database for XTND XMIT. Only two servers implement this however, qpopper is one of them. Also, look in the qpopper source code. It is fully documented there. That's where I found it the first time. > And about HA for Qpopper, are you saying that you have HA > agent for Qpopper ? It is much more complex than that. We wrote a lot of code. But, we are also a software development house. We did a fully distributed architecture that apportioned users over a large number of hosts, allowing us to keep the user load limited, dependent on host capacity and expected load. I have heuristics that calculate that. It is a front-end application system, similar to what AOL has to run.

pop server in an ISP environment
by Muljawan Hendrianto 29 May '00

29 May '00

Hello all, I would like to have your opinions regarding pop server set-up in an ISP environment, what would be the common software used, authentication type etc. I am thinking about using QPOPPER+procmail, but some people say that it is not scalable because its authentication is based on /etc/passwd. And in Unix environment there is certain recommendation not to have more than 5000 users in /etc/passwd file. Another issue is high availability, does any body use server clustering in an ISP environment? I am thinking about having a Sun Cluster for these pop servers, but will I need a special HA agent ? AFAIK, the qpopper daemon will be initiated by the users (via inetd) when they are accessing their mailbox. Hence a Sun cluster will not need a special agent because, if one of the servers crashed, the clustering software should manage to redirect any traffic to the second server, so that the users will connect transparently to that qpopper daemon in the second server. Does clustering in the real world can do the above scenario? What about LDAP for user's authentication ? Is it recommended to use ? Any suggestions/hints will be greatly appreciated. ps: the system should be able to accomodate about 20000 users. regards, Muljawan

It seems 12.0 not, because I can't find the discription of tha command. pls help, thanks!
