Здравствуйте
Использую VisIt для разглядывания результатов МГД-симуляции. Данные сидят на машине trunk (ubuntu 12 LTS; версии VisIt пробую разные - 2.8.2, 2.9.1, 2.9.2), смотрю их с различных машин.
Пока работало, оно работало так: запускаю VisIt локально, в нем создаю профиль удаленной машины trunk. В меню открытия файлов указываю trunk, оно чего-то там пыщь-пыщь, возможно пароль ssh, «launch metadata server» ... и вижу данные на ней.
Теперь, с обновлением версии VisIt локально и, видимо, с обновлением ubuntu зависает на стадии «launching metadata server»
В процессах так:
31838 ? Ss 0:00 | \_ /usr/local/visit/bin/../current/linux-x86_64/bin/python /usr/local/visit/bin/frontendlauncher.py /usr/local/visit/bin/visit -v 2.9 -vcl -debug 5 -noloopback -sshtunneling -host localhos
31847 ? S 0:00 | \_ /usr/local/visit/2.9.1/linux-x86_64/bin/vcl -debug 5 -noloopback -sshtunneling -host localhost -port 28806 -key 2accd4caf640
31848 ? Z 0:00 | \_ [vcl] <defunct>
При этом на сервере появляется такой лог:
/usr/local/visit/2.9.1/linux-x86_64/bin/vcl -noloopback -sshtunneling -host localhost -port 28806 -key 2acc267d4cbe455af640

Все это получается при работе из виртуалки+Ubuntu14LTS с рабочего компа. Однако, виртуалка не при чем, тот же эффект с других машин с нативной убунтой. На ноуте стоит VisIt 2.8.0 и все работает, боюсь на него дыхнуть; при использовании 2.8.0 локально появляются другие проблемы, поэтому тож не вариант.
Официальный FAQ (from here https://wci.llnl.gov/simulation/computer-codes/visit/faqs/faq16) читал, но не помогло. В интырнетах забанили.
Какие-нибудь идеи? Прошу по существу.
Спасибо.
