I have just spent a few hours on this :(
What I wrote initially is correct: ssh doesn't crash when the ssh
lines are removed from the services file.
But neither having a CR nor shortening the line have much
to do with the problem.
The only reason they made a difference is that I had the services
file opened in Word. In that case the getservbyname call fails
cleanly and ssh uses the default.
The real problem is that the s_proto pointer of the struct servent
returned by the Windows getservbyname on Win95 is invalid.
That didn't matter before dup_ent was introduced.
The problem concerns all services, not only ssh, and also
affects getservbyport.

I attach the getserv.c program, in case others want to experiment.
A solution would be to use IsBadStringPtr (or wincap) in dup_ent.
A workaround is to delete lines in the services file.

Ok, so how do you suggest to react in the script if that happens?
Should the script just emit a warning or should it append the ssh lines
at the end of the services file? The new script will just emit a
warning for now.

Ouch. How many spaces do I emit currently... hmm, 27. This matches
the file layout on NT. A quick look on a 98 machine... yes, only
18 spaces. Oh boy...
> Please send the next version, just to be sure.
I've created a new script and attached it to this mail.
Changes:
- Emit a warning if ssh couldn't be added to services file.
- Accomodate different service file layout on 9x and NT.
- On NT: Only ask for installing sshd as service if it's not
already installed.
Please give it a try,
Corinna

I receive a similar stackdump on XP Home, but only when I use the user under which sshd has been installed. When I use root, ssh works fine.

Ouch. I see why that happens. I'll have to modify the ssh-host-config script. This is no problem on 98/Me and NT, though. Did you also test with ssh/22 lines with CRLF?

I observed a ssh crash on Win95 too, but only after running ssh-host-config It went away after deleting the two ssh 22/ lines in c:\windows\services They don't seem to end with CRNL. I am not equipped to do serious debugging on my Win95 machine, strace shows nothing of interest, the stackdump points to cygwin_getservbyname and dup_ent. ~: cat ssh.exe.stackdump Exception: STATUS_ACCESS_VIOLATION at eip=610DF651 eax= ebx=00530740 ecx= edx=0053 esi=0010 edi=0053 ebp=0085F678 esp=0085F674 program=\\WORLDNET\C\SSH.EXE cs=0137 ds=013F es=013F fs=4227 gs= ss=013F Stack trace: Frame Function Args 0085F678 610DF651 (0053, 7E2E3D84, 0032, ) 0085F6C8 61060914 (, 00530732, 0002, A2038AB0) 0085F718 6106215A (0040B221, 0040B225, F48CC23C, C59AB5C7) 0085FBB8 0040B5EE (616966CC, 00438FD0, , 0002) ~: addr2line -e /bin/cygwin1.dll -f 0x610DF651 ?? ../../../../../../src/newlib/libc/machine/i386/strlen.S:27 ~: addr2line -e /bin/cygwin1.dll -f 0x61060914 _Z7dup_entPvS_11struct_type /eroot/obj/i586-pc-cygwin/winsup/cygwin/../../../../src/winsup/cygwin/net.cc :387 ~: addr2line -e /bin/cygwin1.dll -f 0x6106215A cygwin_getservbyname /eroot/obj/i586-pc-cygwin/winsup/cygwin/../../../../src/winsup/cygwin/net.cc :954 Pierre -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
