The results could be useful to a lot of people, so I'm posting everything here. Maybe it can become part of a contrib/ dir in the distribution. mind you, none of this has been written with elegance or efficiency in mind. but it's a good basis for other work. Here's a python module that parses the XML pure-ftpwho data and returns a list of dicts, with each dict representing a connected client's attributes: #! /usr/bin/python2 import os from xml.sax import handler, make_parser class ftpwho_handler(handler.ContentHandler): def __init__(self): handler.ContentHandler.__init__(self) self.clear() def startElement(self, name, attrs): if name != 'client': return d = {} for (k, v) in attrs.items(): d[k] = v self.clients.append(d) def clear(self): self.clients = [] parser = make_parser() fh = ftpwho_handler() parser.setContentHandler(fh) def numberize(dicts): for c in dicts: for k in ('pid', 'time', 'localport', 'percentage', 'bandwidth'): if c.has_key(k): c[k] = int(c[k]) for k in ('current_size', 'resume', 'total_size'): if c.has_key(k): c[k] = long(c[k]) return dicts def clients(): fh.clear() parser.parse(os.popen('pure-ftpwho -x')) return numberize(fh.clients) Building on that, I wrote html_ftpwho.py, which turns the aforementioned client list into HTML output. The output resembles what you get with "pure-ftpwho -w", but you can choose which columns you want in which order, and sort the rows on multiple fields. You also can see bandwidth totals per account. #! /usr/bin/python2 # vim: sw=4 import getopt import pure_ftpwho import sys from string import capitalize, lower def range_idx(list, first = 1, cmp_func = cmp): for i in range(first+1, len(list)): if cmp_func(list[first], list[i]): return i return len(list) def dcmp(a, b, key): if a.has_key(key): if b.has_key(key): return cmp(a[key], b[key]) else: return 1 else: if b.has_key(key): return -1 else: return 0 def multisort(dicts, keys): if not keys: return dicts dicts.sort(lambda x, y, key=keys[0]: dcmp(x, y, key)) ret = [] first = last = 0 while last < len(dicts): last = range_idx(dicts, first, lambda x, y, k=keys[0]: dcmp(x, y, k)) add = multisort(dicts[first:last], keys[1:]) if(add): ret.extend(add) first = last return ret def col_heading(key): headings = {'pid' : 'PID'} if headings.has_key(key): return headings[key] else: return capitalize(lower(key)) def size_abbrev(num, order=-1): abbr = ['b', 'K', 'M', 'G', 'T'] if order == -1: q = 1 for i in range(len(abbr)): p = pow(1024, i+1) if num < p: return (float(num)/q, abbr[i], i) q = p else: return (float(num)/pow(1024, order), abbr[order], order) def celltext(dict, type): sizes = ['current_size', 'total_size', 'percentage', 'bandwidth'] align = '' ret = '' if type == 'stats': align = ' align="right"' if filter(lambda k, d=dict: d.has_key(k), sizes): bw, abbr, order = size_abbrev(dict['bandwidth']) if order == 0: format = '%d' else: format = '%.1f' sf = format + '/' + format sf += '&nbsp;%s&nbsp;(%d%%&nbsp;-&nbsp;' + format sf += '&nbsp;%s/s)' ret = sf % (size_abbrev(dict['current_size'], order)[0], size_abbrev(dict['total_size'], order)[0], abbr, dict['percentage'], bw, abbr) elif not dict.has_key(type): ret = '&nbsp;' elif type in sizes: ret = size_abbrev(dict[type]) elif type == 'time': align = ' align="right"' str = '' minutes, seconds = divmod(dict[type], 60) hours, minutes = divmod(minutes, 60) days, hours = divmod(hours, 24) if(days): str += '%dd' % days if(hours): str += '%02d:' % hours ret = str + '%02d:%02d' % (minutes, seconds) else: ret = dict[type] return '<td%s>%s</td>' % (align, ret) def html(dicts, order, headings, stream, totals): sorted = multisort(dicts, order) stream.write('''<!DOCTYPE html PUBLIC "-//W3C/DTD XHTML 1.0 Transitional//EN" "DTD/xhtml1-transitional.dtd"> <html> <title>Pure-FTPd server status</title> <body bgcolor="#ffffff" text="#000000"> ''') if(totals): stream.write('<table cellspacing="4" border="2" cellpadding="4">') stream.write('<tr><th>Account</th><th>Total Bandwidth</th></tr>') for k in totals.keys(): stream.write('<tr><td>%s</td>' % k) stream.write('<td>%d&nbsp;%s/s</td></tr>\n' % size_abbrev(totals[k])[:2]) stream.write('</table><BR>\n') stream.write('<div align="center">') stream.write('<table width="100%" cellspacing="4" border="2" cellpadding="4">') for k in headings: stream.write('<th>%s</th>' % col_heading(k)) stream.write('\n') for d in sorted: stream.write('<tr valign="middle">\n') for k in headings: stream.write('%s' % celltext(d, k)) stream.write('\n</tr>\n') stream.write('</table></div></body></html>\n') def arg_expand(list, opts): optmap = { 'A':'account', 'B':'bandwidth', 'C':'current_size', 'F':'file', 'H':'host', 'L':'localhost', 'O':'localport', 'P':'percentage', 'D':'pid', 'R':'resume', 'S':'state', 'T':'time', 'X':'stats', 'Z':'total_size' } for l in opts: if optmap.has_key(l): list.append(optmap[l]) else: print 'unrecognized column %s' % l sys.exit(1) def usage(): print '''usage: html_ftpwho.py [options] -c <orderstr> columns to output (default "AXTSHF") -o <orderstr> sort order (default "
