I don't know if you guys ever encontered this problem while using sshfs. I set up a virtual machine to do some PKGBUILD makepking stuff, because some dependcies need bo be installed and I do not want messed up my host machine. So, I set up a sshfs filesystem connect from a virtualbox arch guest to my arch host. Every thing works fine, but each time I ran to following command, the sshfs just hangs up with the same error bellow. Then, I have to remount it again to get it working. command: find . -name Makefile -print | xargs sed -i "s:/usr/bin/install:/bin/install:g" error: sed: cannot remove ./maintscripts/sedP7sQnH: Transport endpoint is not connected Here is my sshfs mount command: sshfs -o sshfs_sync,no_readahead,sshfs_debug,port=64,idmap=user,reconnect,allow_other,workaround=all techlive@home:/home/abs /home/abs I have tested both following, they are all failed. sshfs -o port=64,idmap=user,reconnect,allow_other,workaround=all techlive@home:/home/abs /home/abs sshfs -o port=64,idmap=user,allow_other techlive@home:/home/abs /home/abs I have googled a lot, but none of them could help. So, What do you guys say, is there a known bug or something?
