[Serusers] What are aliases for?
by Dan Austin 05 Dec '02

05 Dec '02

My guess based on reading the developers and admin guides is that an account could be aliased to a DID number, or internal extension. In testing it doesn't seem to work that way. With two accounts, on a Cisco IP phone and the other on MSN client, calls can be placed based on the SIP account name, but not the alias. Thanks, Dan

Re: [Serusers] Softphone that has STUN or built-in NAT support?
by Jiri Kuthan 05 Dec '02

05 Dec '02

I think kphone (Linux) has STUN support. I heard some rumours about SJPhone, but have never tried it out. Out of hard-phones, snom is probably a very cheap alternative right now, and it has STUN support too. Their old version might have been about $200, but many folks found its physical design inconvenient. There is a new version out now, which should be better in this respect. -Jiri At 06:28 AM 12/5/2002, Dan Austin wrote: >I thought this bit would be easy, ask a few friends to register on my server and >test IM and voice calls.

[Serusers] Softphone that has STUN or built-in NAT support?
by Dan Austin 05 Dec '02

05 Dec '02

I thought this bit would be easy, ask a few friends to register on my server and test IM and voice calls. It turns out each and everyone of them has NAT. A quick run around google tells me if I can find a softphone that supports STUN, or can be configured to use the IP address of the NAT gateway and I'll be set. Unfortunately I cannot find any *free* packages that offer these features. Has anyone come across I hate to think I'll have to acquire Cisco phones for my friends to continue testing. While I'm at it, I also was looking to find the least expensive SIP phone on the market. All I've found so far are links geared to large enterprises or OEMs, nothing a tinkerer could buy. Thanks, Dan

The log was overwritten, but the general format was along these lines: ser (error reading communications packet) serro (error reading communications packet) repeated 3~6 times per attempt to logon with a client, or make changes through SERWeb.

I don't have docbook, but I can look into it. One of my concerns about attempting to write this is that I'm still learning the process. Another is that I only have the one server running RedHat, so the steps will be oriented that way, at least to start. I will integrate you're suggestions and provide another update shortly. My last question/issue is about dependancies. When I started working with SER I already had MySQL install, version 3.23.36 I believe. I could not get the MySQL portion integration to work, and found that permissions were not correctly granted. After manually correcting the permissions, I had errors about the communications between SER and MySQL. I updated MySQL to the latest stable release and client programs, and the integration worked with no manual intervention. This prompts me to want to include a section about software that SER depends on, or can leverage, and identify the minimum revision known to work. For this section I would need feedback about what has worked for others, as it failed for me with MySQL 3.23.36 and worked with 3.23.56, but I am sure there is a version inbetween. It may have also been a problem with the client programs and libraries. I unfortunately do not have the resources to test all combinations, so if people care to send me a note with what versions they have installed, I can digest it into a recommendation section.

Hello, I like the document. Documentation is one of our biggest issues right now and I think that a description (or howto) written by someone who is not involved in development of SER can better describe problems that real users have. Are you familiar with docbook ? We write all the documentation in docbook because it is easy then to convert it to other formats like html, ps, pdf, rtf and so on. If not, then just plaintext will be fine. Some comments are inline. Thank you very much for your effort ! Keep up the good work. regards, Jan.

As long as your text describes what you had to do to make ser and serweb work and describes your problems with the software, you are certainly on the right track. > I'm considering an addition section on client configuration, but I'm > not sure how valuable that will be.

Yes, it will be imho valuable, you can consider also kphone which is a free softphone for linux - http://www.wirlab.net/kphone Content-Description: Ser.htm > 1.2 Why SER > > SER is an open-source project that aims to make available a fully > functional and scalable Session Initiated Protocol suite.

If you don't have the script, you have no ser-mysql package installed.

You can store them as plaintext passwords, which is easier to maintain for ser beginners. Or you can store HA1 strings. HA1 string is a hash that contains username, password and realm hashed using MD5. Advantage of this approach is that passwords are not stored in plaintext and can be seen easily. This is similar to to /etc/passwd in unix, the server doesn't know passwords, it can only use HA1 to verify responses. If you decide to to use plaintext passwords, uncomment the "calculate_ha1" parameter. If you decide to use HA1, make sure that HA1 strings contain correct realm (the default HA1 string for admin user which comes with ser contains iptel.org as the realm). If you change your realm, you must also change all HA1 strings. > Uncomment this line: modparam("auth", "password_column", > "password") Uncomment this line if you use "calculate_ha1" parameter. By default, ser looks into ha1 column for HA1 strings. If you use plaintext passwords, you must tell ser to look into password column for plaintext passwords, this is what this parameter is for. > Basic account manipulation can be performed with the serctl script, > located in /usr/local/sbin. > Once you get familiar with serctl command, it would be handy if you could write a description what this command can do and what it can be used for.
