I’m on a tight deadline and the last thing I need right now is kernel/Asterisk/Zaptel/Sangoma issues… This post may just help someone else save some time:

When running Sangoma’s Setup script from their wanpipe-2.3.4-7 release, the following error occurs when it tries to patch the latest zaptel (version 1.4 checked from SVN revision 2399):

Enable TDMV DCHAN Native HDLC Support & Patch Zaptel ? (y/n) y

Did NOT find the seached str:chan->writen\[chan->inwritebuf\] = amnt;
search_and_replace(zaptel-base.c) failed

Applying the following diff to Setup should solve the problem:

1c1
< #!/bin/sh
---
> #!/bin/bash
6128c6128
< ZAPTEL_C_SEARCH_STR="chan->writen\[chan->inwritebuf\] = amnt;"
---
> ZAPTEL_C_SEARCH_STR="chan->writen\[res\] = amnt;"
6134c6134
<                       chan->writen[chan->inwritebuf] = amnt;"
---
>                       chan->writen[res] = amnt;"

The change from sh to bash was to overcome the following error:

./Setup: 1014: Syntax error: Bad substitution

Finally, it looks like Sangoma’s current wanpipe will not work with linux-2.6.20.x:

/usr/src/wanpipe/kdrvtmp/sdla_xilinx.c:636:62: error: macro "INIT_WORK" passed 3 arguments, but takes just 2
/usr/src/wanpipe/kdrvtmp/sdla_xilinx.c: In function ‘wp_xilinx_init’:
/usr/src/wanpipe/kdrvtmp/sdla_xilinx.c:636: error: ‘INIT_WORK’ undeclared (first use in this function)
/usr/src/wanpipe/kdrvtmp/sdla_xilinx.c:636: error: (Each undeclared identifier is reported only once
/usr/src/wanpipe/kdrvtmp/sdla_xilinx.c:636: error: for each function it appears in.)

It works fine with linux-2.6.19.x.

I have let Sangoma’s support team know of these issues so hopefully they’ll be resolved before anyone has to actually use this post.

In reviewing the agenda from UKNOF which I was regrettably unable to attend, three talks of an Irish origin stood out.

• The realities of LLU in Ireland from Colin Whittaker of Magnet (the title says it all). There was also a British view offered: LLU in the UK;
• NOC Tools from Donal O’Cearbhaill where he discussed the many tools they use at HEAnet to manage, provision and monitor the Broadband for Schools project; and
• Network Architecture of Joost by Colm MacCarthaigh. This one is really interesting in terms of how they plan to manage the massive data transmission requirements of on-demand video and the design of a fault tolerant network service. I really like the way they their code is prefix aware and are planning AS-level awareness. Nice. Actually an interesting thread broke out about this on NANOG at the start of the year.
