To all members,
If you have encountered the "Can't communicate with IIIM Server" error,
please give Descender's solution a try, and if the feedback is positive,
I'll put it up as an FAQ's solution. Also note that after making changes
in the hosts.allow, restore the htt.conf file back to the original form
and see if the error persists. I look forward to your feedback.
Great work Descender!
Thanks,
Lawrence

Hi everyone.
It seems that I'm not the only one getting the 'Can't communicate with
IIIM server' error. It turns out that in my case, the /etc/hosts.allow
and /etc/hosts.deny configuration was overly restrictive.
From /var/log/messages:
Mar 1 15:34:02 dreamerbox htt_server[3563]: started.
Mar 1 15:34:04 dreamerbox htt_server[3563]: Denied the access from
localhost.localdomain.
Mar 1 15:34:16 dreamerbox htt_server[3563]: Denied the access from
localhost.localdomain.
According to the comments in /usr/lib/im/htt.conf, htt_server uses
libwrap (tcp_wrappers) for access control. I took a look at /etc/hosts.
allow and /etc/hosts.deny, and this revealed the cause:
/etc/hosts.deny:
ALL:ALL
/etc/hosts.allow:
(empty)
To get it to work, I simply added this line to /etc/hosts.allow:
htt_server: 127.0.0.1
Next, I restarted the server (may not be necessary as htt_server could
reread /etc/hosts.allow on an connection attempt) with:
service IIim restart
From then on, I no longer get the error. IIIM input works as far as I'm
concerned.
Take note that htt_server now runs as user htt (iiimf-server-11.4-21).
If you get the following message in /var/log/messages, modify the
permissions of /etc/hosts.allow and /etc/hosts.deny such that user htt
can access them:
Mar 1 18:15:47 dreamerbox htt_server[5971]: warning: cannot open /etc/
hosts.allow: Permission denied
That's all.
I hope this works for other folks experiencing the same problem.

P.S. I hope the Simplified Chinese LE gets as good as SCIM's.
