Home -> Community -> Mailing Lists -> Oracle-L -> UNIX Q: Tricky SCP between 3 boxes without creating transient fil
Hello gurus,
Env:
BoxA - outside the firewall. BoxB - inside the firewall BoxC - inside the firewall
BoxA has the file expdat.dmp size 1.9Gb. BoxA has no access to any of the
boxes inside the FW.
BoxB is the only box that can reach out to BoxA through the FW. BoxB has an
exception rule in the FW.
I wanted to copy (using scp) expdat.dmp from BoxA to BoxC. I could have
simply scp'd from BoxB then scp it again to BoxC, however, because of space
restrictions in BoxB, this is not an option.
I was thinking of using 'pipe file' using mkfifo in BoxB to scp (pull) the
file from BoxA then immediately scp (push) the same to BoxC. BoxB is kind of
like a middleman then.
I attempted using my script below but I got an error and core dump.
#!/bin/ksh
#This SCP script executed from BoxB
rm /home/oracle/tmp/fifo mkfifo /home/oracle/tmp/fifo scp -q /home/oracle/tmp/fifo BoxC:/home/oracle &scp -q BoxA:/oracle1/export/expdat.dmp /home/oracle/tmp/fifo
The error is:
/home/oracle/tmp/fifo: not a regular file
Segmentation Fault(coredump)
Are pipe files useable in scp's? How? I know I've used them before in EXPorts that pipes to a gzip but I can't seem to get it to work for scp. I'm only trying to avoid creating a transient copy of expdat.dmp in BoxB. Otherwise, I might have to clear out some space in BoxB (which I'm desperately trying to avoid).
Any suggestions?
Rgds,
Ross
