Synopsis
In
the following ASCII-figured environment, it seemed working in the beginning, but the next error message occurred (in unexpected/unknown timing), and
every time it occurs, I need to press nasty [ok] many times. That has been my headache.
Thanks
to yutakapon san, Tera Term's coming version 4.84 will also improve my experience of web browsing through SSH tunnel (under sshd + proxy server).
Environment
PC + Tera Term + forwarding (port 3128/tcp) + browser with proxy (my_PC:3128)

tunnel under low quality network)

Error
Message (English)
A
communications error occurred while sending forwarded data to a local
port. The forwarded connection will be closed.
Error
Message (Japanese)
ローカルポートに転送データを送信中、通信エラーが発生しました。転送接続を閉じます。

Cause and History
In case I open many sessions (for HTTP communication
through SSH tunnel) at a time,
a
certain kind of error {in the condition “if(!UTIL_sock_buffered_write
...)”} occurs, I guess.
Ref: http://sourceforge.jp/projects/ttssh2/scm/svn/blobs/head/tags/teraterm-4_82/ttssh2/ttxssh/fwd.c
1839th:
if(!UTIL_sock_buffered_write ...)
1845th:
notify_nonfatal_error(pvar, pvar->ts->UIMsg);
(It
doesn't occur when I use a single session in the different application like
POP3 and so on.)
The
error situation seems common in Tera Term 4.66, 4.76, 4.82.
So,
I requested to stop “notify_nonfatal_error” (partly), and then Tera Term project
person kindly corresponded that it will be implemented in the future
version 4.84.
unfortunately
the link becamse unavailable now.) ,
which doesn't cause error
message and doesn't require me nasty operation to press [ok].
In the
temporal cure version, {probably/mainly because of the continuing condition "!UTIL_sock_buffered_write ...",} browsing seems still slower than direct
connection to the internet without proxy, but I highly appreciate the fact that it doesn't require to press [ok] anymore.
I
hereby wrote rough translation in English, for the sake of English-speaking users, paying respect to the project people. Thank you all who are in the project for the great software, Tera Term.
