Qpopper 4.0.16 Upgrade on a Solaris 5.7 System

For anyone who might be encountering problems building Qpopper or other software on a Solaris system and seeing a checking size of unsigned long int... configure: error: cannot compute sizeof (unsigned long int), 77 error message at the configure stage or seeing ld: fatal: Symbol referencing errors at the make stage, try running configure with CFLAGS=-gstabs+, i.e. try ./configure CFLAGS=-gstabs+. Since Solaris uses shadow passwords, you should also use the --enable-specialauth option as well, i.e. use the following configure command:

./configure --enable-specialauth CFLAGS=-gstabs+

Otherwise, Qpopper won't likely accept an account's password when you try to download email. Using those options at the configure step allowed me to resolve issues I was having installing Qpopper 4.0.16 on a Solaris 5.7 system.

I've included everything I did while working on the problem below for my own future reference and in case it might help someone else encountering the same or similar problem who is searching for webpages with information on the problem.

I was notified of a security vulnerability related to Qpopper on a Sun SPARC system running Solaris 5.7, which was detected during Foundstone security scanning of the network on which the system resided. I checked the version of qpopper currently on the system by connecting to the POP3 port, which is port 110, on the server. I saw a banner indicating the version was 4.0.5

# telnet 127.0.0.1 110 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. +OK Qpopper (version 4.0.5) at taiyou1.example.com starting. <27561.1238007666@example.com>

I wasn't sure where the executable files for qpopper were on the hard drive for qpopper or what other files associated with the software were on the system. I found popper and popauth in /usr/local/sbin.

# ls -l /usr/local/sbin/pop*
-rwsr-xr-x   1 pop      root       35968 Mar 26  2003 /usr/local/sbin/popauth
-rwxr-xr-x   1 root     other     143336 Mar 26  2003 /usr/local/sbin/popper
# /usr/local/sbin/popper -v
Qpopper version 4.0.5 (non-standalone)
# /usr/local/sbin/popauth -version
/usr/local/sbin/popauth v4.0.5

I also found a popauth file in /usr/local/lib.

# ls -l /usr/local/lib/pop*
-rwsr-xr-x   1 pop      other     195716 Apr  5  2001 /usr/local/lib/popauth

I found the man files in /usr/local/man/man8.

# ls -l /usr/local/man/man8/pop*
-rw-r--r--   1 root     other       2211 Mar 26  2003 /usr/local/man/man8/popaut
h.8
-rw-r--r--   1 root     other      21370 Mar 26  2003 /usr/local/man/man8/popper
.8

I found popauthd in /usr/local/libexec/popauthd. 

# ls -l /usr/local/libexec/popauthd
-rwxr--r--   1 root     other       2411 Mar 19  2003 /usr/local/libexec/popauth
d

The popauthd daemon is being run from /etc/init.d/popauthd. 

# ls -l /etc/init.d/pop*
-rwxr--r--   2 root     other        122 Aug 14  2002 /etc/init.d/popauthd

The file contains the following lines:

pauthd.sh

[ -x /usr/local/libexec/popauthd ] && { 
        /usr/local/libexec/popauthd &
        echo -n ' popauthd'
}

I had also placed the following lines in /etc/inetd.conf back in 2001 when I set up the system.

# Post Office Protocol - added 4/05/01 by JMC
# The "-s" option enables statistics logging.  After each session ends,
# a statistics record is written to the log, which contains the username,
# deleted msgs, deleted octets, msgs left on server, octets left on server,
# the name of the client machine, and the IP address of the client machine.
# The "-p 2" option specifies the clear text handling option when APOP
# is available.  The "2" indicates that clear text passwords are always
# permitted (even if an APOP entry exists).
pop3 stream tcp nowait root /usr/local/sbin/popper qpopper -s -p 2

There are also files in /etc associated with APOP authorization. 

# ls -l /etc/pop*
-rw-------   1 pop      other          0 Apr  5  2001 /etc/pop.auth
-rw-------   1 pop      pop            0 Apr  5  2001 /etc/pop.auth.dir
-rw-------   1 pop      pop         1024 Jul  6  2007 /etc/pop.auth.pag
-rw-------   1 pop      other         15 Apr  5  2001 /etc/pop.noauth
To address the security vulnerability, I downloaded the latest version of Qpopper from Qualcomm's ftp site or from a mirror site.

I decompressed the downloaded file and extracted its contents.

At first, before I encountered problems installing the software, I was going to create a Solaris package to use for the installation, so I created a temporary installation directory, in this case /usr/local/pkg.

# mkdir /usr/local/pkg

I specified the temporary installation directory when I ran configure.

# ./configure --prefix=/usr/local/pkg

When I ran make install, I received an error message regarding a missing directory. I then created that directory.

# make install

Again, an error occurred. I tried running ./configure without specifying the installation directory. I then ran make, but got the same results as before.

I downloaded an older version, 4.0.13, to see if I would have the same problem installing it. 

# wget -q ftp://ftp.qualcomm.com/eudora/servers/unix/popper/qpopper4.0.13.tar.gz
# gunzip qpopper4.0.13.tar.gz
# tar -xvf qpopper4.0.13.tar
# cd qpopper4.0.13

I then ran configure for that version.

See `config.log' for more details.

Since I got an error message when attempting to run configure for that version, I downloaded an even older version.

# wget -q ftp://ftp.qualcomm.com/eudora/servers/unix/popper/old/qpopper4.0.7.tar
.gz
# gunzip qpopper4.0.7.tar.gz
# tar -xvf qpopper4.0.7.tar
# cd qpopper4.0.7

I then ran configure for that version. But, I received an error message for that version as well, though it was a different error message.

In the configure.in file, I found the following:

    AC_CHECK_LIB(dl, dlopen, LIBS="$LIBS -ldl")
    AC_CHECK_LIB(pam, pam_authenticate, LIBS="$LIBS -lpam",
                 AC_MSG_RESULT([Can't use PAM: can't find libpam]);exit 1)
fi

I found someone else complaining at qpopper won't compile without PAM that "qpopper won't compile on systems without PAM anymore."

I tried recompiling with the --without-pam option, but that only got me to the same checking size of unsigned long int... configure: error: cannot compute sizeof (unsigned long int), 77 error message I had with version 4.0.13.

# cd qpopper4.0.14

I ran ./configure. Again, I received the checking size of unsigned long int... configure: error: cannot compute sizeof (unsigned long int), 77 error.

I tried compiling the 4.0.16 version again. I ran make realclean first.

# cd qpopper4.0.16
# make realclean
I saw a warning, but no error messages when I ran ./configure

I thought the problem might be related to some library file needed by popper not being present or just being out-of-date, so I checked on the dependencies of the current version of popper on the system with ldd

# ldd /usr/local/sbin/popper
        libnsl.so.1 =>   /usr/lib/libnsl.so.1

I checked on the current value for LD_LIBRARY_PATH, also.

# echo $LD_LIBRARY_PATH

I also checked on the package to which /usr/lib/libnsl.so.1 belonged.

I didn't understand why I saw the following lines output when I ran configure.

checking for gethostname... no
checking for gethostbyname... no
checking for gettimeofday... no
checking for getusershell... no

Nor did I understand why I saw the following lines when I afterwards ran make.

The gethostbyname and gethostbyaddr functions seemed to be in /usr/lib/libnsl.so.1.

I checked the config.log file produce when I ran configure. The first sign of a problem I found in it was on the following lines:

configure:2905: checking for library containing strerror
configure:2946: gcc -o conftest -g -O2 conftest.c >&5
ld: fatal: relocation error: R_SPARC_32: file /var/tmp//ccatA7Kv.o: symbol <unknown>: offset 0xff0a131f is non-aligned

configure: failed program was:

| #define PACKAGE_NAME ""
| #define PACKAGE_TARNAME ""
| #define PACKAGE_VERSION ""
| #define PACKAGE_STRING ""
| #define PACKAGE_BUGREPORT ""
| /* end confdefs.h. */

Later in the log, I saw the following:

configure:10382: checking for gethostname
configure:10438: gcc -o conftest -g -O2 -fpcc-struct-return conftest.c >&5
ld: fatal: relocation error: R_SPARC_32: file /var/tmp//ccS99rIb.o: symbol : offset 0xff0a12fe is non-aligned

collect2: ld returned 1 exit status

At Getting around smartmontools linker errors, I found someone reporting on ld: fatal: relocation error: R_SPARC_32 errors when trying to build smartmontools on a Solaris system. Someone reported there that using CFLAGS=-gstabs+ resolved the problem.

At Debugging Options - Using the GNU Compiler Collection (GCC), I found the following information for the -g option:

On most systems that use stabs format, -g enables use of extra debugging information that only GDB can use; this extra information makes debugging work better in GDB but will probably make other debuggers crash or refuse to read the program. If you want to control for certain whether to generate the extra information, use -gstabs+, -gstabs, -gxcoff+, -gxcoff, or -gvms (see below).

The information for the -gstabs+ option is as follows:

-gstabs+

Produce debugging information in stabs format (if that is supported), using GNU extensions understood only by the GNU debugger (GDB). The use of these extensions is likely to make other debuggers crash or refuse to read the program.

So I ran make realclean then configure with CFLAGS=-gstabs+.

This time I saw the following output by the configure process:

checking for gettimeofday... yes
checking for getusershell... yes

During previous executions of configure for qpopper 4.0.16, I had seen the following for those same lines:

checking for gethostname... no
checking for gethostbyname... no
checking for gettimeofday... no
checking for getusershell... no
<text snipped>
checking for library containing gethostbyname... no

I then ran make again, without errors this time.

Installed popper as /usr/local/sbin/popper

I then connected to the POP3 port, i.e. port 110, to check the Qpopper banner.

# telnet 127.0.0.1 110
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
+OK Qpopper (version 4.0.16) at taiyou1.example.com starting.

Connection closed by foreign host.

I also checked the version with popper -v.

# /usr/local/sbin/popper -v
Qpopper version 4.0.16 (non-standalone)

So, at last, the upgrade was successful. But, when I then tried checking email for my account with Outlook, I kept getting prompted for my password, though I knew I was entering the correct password. I tried connecting to the POP3 port by telnet and checking that way as well to see what error messages I might see that way. But there was no error message displayed other than one indicating the password was incorrect, which was not the case.

Since qpopper was being started through /etc/inetd.conf, I killed the inetd.conf process, just to see if there would be any change in results, and tried again. I got the same -ERR [AUTH] Password supplied for "jsmith" is incorrect message. I wasn't really expecting that stop to make a difference, since I hadn't changed /etc/inetd.conf.

I checked /var/log/poplog to see if there might be any clue regarding the problem there. There was nothing of use to me there, either.

Mar 27 14:43:08 taiyou1 qpopper[12877]: jsmith at localhost (127.0.0.1): -ERR [AUTH] Password supplied for "jsmith" is incorrect. Mar 27 14:43:08 taiyou1 qpopper[12877]: [AUTH] Failed attempted login to jsmith from host (localhost) 127.0.0.1

After checking postings I found online regarding login problems, I decided to rebuild the software and use the following option with configure, since Solaris is using shadow passwords.

 --enable-specialauth     Enable secure crypt or shadow passwords

I then issued the commands below:

# make realclean
# ./configure --enable-specialauth CFLAGS=-gstabs+
# make
# make install

That resolved the problem.
