Even on local system, I have 11(13 if elevated) groups attached to my userid. Perhaps, the execution of the id -G has been influenced by your current (at that moment) /etc/group file. > To create a bash terminal window (from cmd) takes about 5-6 minutes. > cmd /v:on /c "echo !TIME! & C:\cygwin64\bin\mintty.exe /bin/echo "test" & echo !TIME!" > 11:01:20.27 > 11:06:59.78 = 5:39.51 > Starting cygserver: > 11:08:31.55 > 11:08:31.62 = 0:00.07 > Stopping it again: > 11:09:19.02 > 11:15:04.45 = 05:45.43 > With the 'db' entry excluded as a control: > 11:15:56.80 > 11:15:56.90 = 00:00.10 > I reverted back to use files+db and my larger passwd and group files, turned on cygserver: > 11:19:34.31 > 11:19:34.38 = 00:00.07 Could you please do me a favor and repeat the test with a little deviation of my previous suggestion? 1. Remove /etc/{nsswitch.conf,passwd,group} files. (Rename, move away - by your choice.) 2. Stop cygserver, if it is running, and any other Cygwin-related programs. 3. Start the mintty (elevated, if need) with write access to /etc. Supposedly, this will be slow. 4. Make sure id -G lists all the groups you're member of. The `id -znG | tr "\0" "\n"` would probably be more visible. 5. Repeat the steps from previous suggestion. getent passwd $(id -u) > /etc/passwd getent group $(id -G) > /etc/group printf "%s\n" "passwd: files db" "group: files db" > /etc/nsswitch.conf 6. Close and restart mintty -- WBR, Andrey Repin (anrdaemon AT yandex DOT ru) 17.02.2015, <13:35> Sorry for my terrible english... -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
